1.5	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.4	24-Apr-2021	thorpej	branches: 1.4.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.3	12-Dec-2018	is	branches: 1.3.14; Added support for AMD family 16h cpu sensors - (just like 10h-14h). (Tested on netbsd-8.0 release.)
1.2	16-Apr-2012	cegger	branches: 1.2.2; 1.2.4; 1.2.36; 1.2.42; 1.2.44; Add rescan support. Re-fixes PR 45268.
1.1	13-Apr-2012	cegger	Replace amdtempbus with amdnb_miscbus. This allows us to have independent drivers on the same device (northbridge f3) each coming with a certain functionality/feature. This way we do not need to mess with amdtemp(4) to utilize other features.
1.2.44.1	10-Jun-2019	christos	Sync with HEAD
1.2.42.1	26-Dec-2018	pgoyette	Sync with HEAD, resolve a few conflicts
1.2.36.1	15-Dec-2018	martin	Pull up following revision(s) (requested by is in ticket #1137): sys/arch/x86/pci/amdnb_misc.c: revision 1.3 sys/arch/x86/pci/amdtemp.c: revision 1.22 Added support for AMD family 16h cpu sensors - (just like 10h-14h). (Tested on netbsd-8.0 release.)
1.2.4.2	29-Apr-2012	mrg	sync to latest -current.
1.2.4.1	16-Apr-2012	mrg	file amdnb_misc.c was added on branch jmcneill-usbmp on 2012-04-29 23:04:43 +0000

1.2.2.1	16-Apr-2012	yamt	file amdnb_misc.c was added on branch yamt-pagecache on 2012-04-17 00:07:05 +0000
1.3.14.7	05-Apr-2021	thorpej	config_match() -> config_probe() for the straight-forward indirect config cases. There are still a few odd balls using config_match() which should be sorted out later.
1.3.14.6	04-Apr-2021	thorpej	CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
1.3.14.5	03-Apr-2021	thorpej	Give config_attach() the tagged variadic argument treatment and mechanically convert all call sites.
1.3.14.4	28-Mar-2021	thorpej	These devices have only one interface attribute and no locators, so simplify: - config_attach_loc() -> config_attach(). - Don't pass CFARG_IATTR, or CFARG_LOCATORS to config_search().
1.3.14.3	21-Mar-2021	thorpej	In "rescan" routines, always pass locators and the interface attribute straight through to config_search(). Also, for devices that carry only one interface attribute, no need to do an ifattr_match(), because rescan_with_cfdata() will have already validated that the parent is eligible, which includes an interface attribute check.
1.3.14.2	21-Mar-2021	thorpej	CFARG_IATTR usage audit: If a device carries only one interface attribute, there is no need to specify it when calling config_search(); that specification is meant only to disambiguate which interface attribute (which is a proxy for "what kind of attach args are being used") is having children attached. cfparent_match() will take care of ensuring that any potential children can attach to one of the parent's iterface attributes, and if the parent only carries one, no disambiguation is necessary.
1.3.14.1	20-Mar-2021	thorpej	The proliferation if config_search_() and config_found_() combinations is a little absurd, so begin to tidy this up: - Introduce a new cfarg_t enumerated type, that defines the types of tag-value variadic arguments that can be passed to the various config_() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS, for now, plus a CFARG_EOL sentinel). - Collapse config_search_() into config_search() that takes these variadic arguments. - Convert all call sites of config_search_*() to the new signature. Noticed several incorrect usages along the way, which will be audited in a future commit.
1.4.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
1.5	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.4	24-Apr-2021	thorpej	branches: 1.4.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments.

1.6.6.1	25-Apr-2020	bouyer	Sync with bouyer-xenpvh-base2 (HEAD)
1.10.4.6	05-Apr-2021	thorpej	config_match() -> config_probe() for the straight-forward indirect config cases. There are still a few odd balls using config_match() which should be sorted out later.
1.10.4.5	04-Apr-2021	thorpej	CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
1.10.4.4	03-Apr-2021	thorpej	config_attach_loc() -> config_attach() with CFARG_LOCATORS argument.
1.10.4.3	28-Mar-2021	thorpej	These devices have only one interface attribute and no locators, so simplify: - config_attach_loc() -> config_attach(). - Don't pass CFARG_IATTR, or CFARG_LOCATORS to config_search().
1.10.4.2	21-Mar-2021	thorpej	In "rescan" routines, always pass locators and the interface attribute straight through to config_search(). Also, for devices that carry only one interface attribute, no need to do an ifattr_match(), because rescan_with_cfdata() will have already validated that the parent is eligible, which includes an interface attribute check.
1.10.4.1	20-Mar-2021	thorpej	The proliferation if config_search_() and config_found_() combinations is a little absurd, so begin to tidy this up: - Introduce a new cfarg_t enumerated type, that defines the types of tag-value variadic arguments that can be passed to the various config_() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS, for now, plus a CFARG_EOL sentinel). - Collapse config_search_() into config_search() that takes these variadic arguments. - Convert all call sites of config_search_*() to the new signature. Noticed several incorrect usages along the way, which will be audited in a future commit.
1.11.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().

Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.27	12-Apr-2023	riastradh	ichsmb(4), tco(4): Add support for TCO on newer Intel chipsets. TCO (`Total Cost of Ownership', Intel's bizarre name for a watchdog timer) used to hang off the Intel I/O platform controller hub's (ICH) low-pin-count interface bridge (LPC IB), or ichlpcib(4). On newer devices, it hangs off the ICH SMBus instead. Tested on INTEL 100SERIES_SMB (works) and INTEL 100SERIES_LP_SMB (doesn't work, still not sure why). XXX kernel revbump: This breaks the module ABI -- tco(4) modules older than the change to make ta_has_rcba into ta_version will incorrectly attach at buses they do not understand. (However, the tco(4) driver is statically built into GENERIC, so maybe it's safe for pullup since the module wouldn't have worked anyway.)

Tested on Intel SS4200-E (ICH7), and Acorp 6A815EPD (ICH2) motherboards, on amd64 and i386 ports respectively. It should be noted that the majority of boards with ICH chips do not expose the GPIO pins for off-board use. For instance, aside from the three exposed-on-a-header pins on the 6A815EPD, another pin is also used to control write protect on the FWH. The SS4200 exposes the GPIO on a header that connects to the 10 LEDs on the front panel, as well as a tact switch on the back panel.

1.26.16.1	01-Aug-2023	martin	Pull up following revision(s) (requested by riastradh in ticket #282): sys/dev/pci/ichsmb.c: revision 1.82 sys/arch/amd64/conf/GENERIC: revision 1.602 sys/arch/x86/pci/tco.c: revision 1.10 sys/arch/x86/pci/tco.h: revision 1.5 sys/arch/x86/pci/ichlpcib.c: revision 1.59 sys/dev/ic/i82801lpcreg.h: revision 1.17 sys/arch/x86/pci/files.pci: revision 1.27 sys/dev/pci/files.pci: revision 1.446 ichsmb(4), tco(4): Add support for TCO on newer Intel chipsets. TCO (`Total Cost of Ownership', Intel's bizarre name for a watchdog timer) used to hang off the Intel I/O platform controller hub's (ICH) low-pin-count interface bridge (LPC IB), or ichlpcib(4). On newer devices, it hangs off the ICH SMBus instead. Tested on INTEL 100SERIES_SMB (works) and INTEL 100SERIES_LP_SMB (doesn't work, still not sure why). XXX kernel revbump: This breaks the module ABI -- tco(4) modules older than the change to make ta_has_rcba into ta_version will incorrectly attach at buses they do not understand. (However, the tco(4) driver is statically built into GENERIC, so maybe it's safe for pullup since the module wouldn't have worked anyway.)

1.8	16-Nov-2014	ozaki-r	branches: 1.8.2; Replace callout_stop with callout_halt In order to call callout_destroy for a callout safely, we have to ensure the function of the callout is not running and pending. To do so, we should use callout_halt, not callout_stop. Discussed with martin@ and riastradh@.

1.6	17-Oct-2013	christos	branches: 1.6.2; remove set but unused variables
1.5	02-Feb-2012	tls	branches: 1.5.2; 1.5.6; 1.5.10; Entropy-pool implementation move and cleanup. 1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev. 2) Remove use of NRND as test for presence of entropy-pool code throughout source tree. 3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit. 4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources. 5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each. ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.
1.4	19-Nov-2011	tls	branches: 1.4.2; First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following: An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time. A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available. The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time. An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm. A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream. An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice. In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve. The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component. The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run. A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl. The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet. Manual pages for the new kernel interfaces are forthcoming.

1.61	09-May-2023	riastradh	branches: 1.61.6; ichlpcib(4): Use config_detach_children. Delete a lot of unnecessary code with broken error branches involving config_detach which have probably seldom if ever been exercised. No substantive functional change intended. Low risk because ichlpcib(4) is not a removable device, so you have to go out of your way to exercise detach.
1.60	09-May-2023	riastradh	ichlpcib(4): KNF. No functional change intended.
1.59	12-Apr-2023	riastradh	ichsmb(4), tco(4): Add support for TCO on newer Intel chipsets. TCO (`Total Cost of Ownership', Intel's bizarre name for a watchdog timer) used to hang off the Intel I/O platform controller hub's (ICH) low-pin-count interface bridge (LPC IB), or ichlpcib(4). On newer devices, it hangs off the ICH SMBus instead. Tested on INTEL 100SERIES_SMB (works) and INTEL 100SERIES_LP_SMB (doesn't work, still not sure why). XXX kernel revbump: This breaks the module ABI -- tco(4) modules older than the change to make ta_has_rcba into ta_version will incorrectly attach at buses they do not understand. (However, the tco(4) driver is statically built into GENERIC, so maybe it's safe for pullup since the module wouldn't have worked anyway.)
1.58	22-Sep-2022	riastradh	branches: 1.58.4; ichlpcib(4), tco(4): Rename iot -> pmt, ioh -> pmh. Makes it clearer that this is specifically about the power management controller (PMC) registers relative to PMBASE.
1.57	22-Sep-2022	riastradh	ichlpcib(4), tco(4): Take `lpcib_' off various names. For PMC-specific ones, change `lpcib_' to `pmc_'. These are in a separate PCI device in newer chipsets. For TCO-specific ones, which may live in different places, whether at their own base address or as an offset from PMBASE, just leave it as `tco_' or `tcotimer'. No functional change intended.
1.56	22-Sep-2022	riastradh	tco(4): Rename lpcib_tco_attach_args -> tco_attach_args. No longer hangs off LPC bus, newer devices hang it off SMBus.
1.55	22-Sep-2022	riastradh	tco(4): Change has_rcba bit into version number. Will be useful for newer Intel platform controller hubs. No functional change intended. Module ABI is unchanged, although older modules will do something nonseneical when confronted with versions above 1 -- that will require a revbump (but with any luck, it will make life easier for versions above 2 easier once we do that).
1.54	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.53	24-Apr-2021	thorpej	branches: 1.53.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

The GPIO lines on an ICH are usually connected to opaque platform- defined functionality, and may be manipulated by the ACPI DSDT or other mechanisms behind our backs. In one instance, it was found this in combiation with gpio_resume() sabotaged repeated suspend/resume cycles. GPIO functionality can be enabled by setting ichlpcib_gpio_disable to 0, for instance with `gdb -write`.

1.46	13-Jan-2015	msaitoh	As I wrote in the last commit, The PMBASE and GPIOBASE registers are not compltible with the PCI spec and the map sizes are fixed to 128bytes. The pci_mapreg_submap() function has a code to check the range of the BAR. The PCI_MAPREG_IO_SIZE() macro returns lower than 128bytes on some machines. It makes impossible to use pci_mapreg_submap(). Use pci_conf_read() and bus_space_map() directly. Observed and tested with my Thinkpad X61.
1.45	26-Dec-2014	msaitoh	Fix a bug that ichlpcib(4) maps I/O area incorrectly and then fails to attach gpio. It might also fix ACPI related problem described in PR#48960: - The LPCIB_PCI_PMBASE and LPCIB_PCI_GPIO register are alike PCI BAR but not completely compatible with it. It's ok because the registers' addresses are out of BAR0-BAR5(0x10-0x24) and are located in the device-dependent header. The PMBASE and GPIO registers define the base address and the type but not describe the size. The size is fixed to 128bytes. So use pci_mapreg_submap(). - Make pci_mapreg_submap() extern again. - Fix the calculation of the map size in pci_mapreg_submap().

1.29	04-Apr-2011	dyoung	branches: 1.29.2; Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9), pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match predicate passed to pciide_compat_intr_establish() should ever modify their pci_attach_args argument, so make their pci_attach_args arguments const and deal with the fallout throughout the kernel. For the most part, these changes add a 'const' where there was no 'const' before, however, some drivers and MD code used to modify pci_attach_args. Now those drivers either copy their pci_attach_args and modify the copy, or refrain from modifying pci_attach_args: Xen: according to Manuel Bouyer, writing to pci_attach_args in pci_intr_map() was a leftover from Xen 2. Probably a bug. I stopped writing it. I have not tested this change. siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args. Probably a bug. I use a temporary variable. I have not tested this change. slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args. Probably a bug. Use a local pci_attach_args. I have not tested this change. viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the caller's pci_attach_args. Probably a bug. Make a local copy of the caller's pci_attach_args and modify the copy. I have not tested this change. While I'm here, make pci_mapreg_submap() static.

1.28	06-Sep-2010	christos	branches: 1.28.2; make it compile.
1.27	17-Aug-2010	jakllsch	Match ichlpcib(4) on ICH0 (82801AB_LPC).
1.26	23-Jul-2010	jakllsch	Finish cleaning up pchb from recent change. Use fewer magic numbers in ichlpcib. Slightly improve style conformance. Update paths in cpp re-inclusion guards.
1.25	23-Jul-2010	jakllsch	Almost entirely rework Intel Firmware Hub random number generator support. This introduces fwhrng(4) which attaches via ichlpcib(4), replacing the rnd(4) support in pchb(4).
1.24	24-Feb-2010	dyoung	branches: 1.24.2; A pointer typedef entails trading too much flexibility to declare const and non-const types, and the kernel uses both const and non-const PMF qualifiers and device suspensors, so change the pmf_qual_t and device_suspensor_t typedefs from "pointers to const" to non-pointer, non-const types.
1.23	08-Jan-2010	dyoung	branches: 1.23.2; Expand PMF_FN_* macros.
1.22	08-Jan-2010	dyoung	Move all copies of ifattr_match() to sys/kern/subr_autoconf.c.
1.21	27-Sep-2009	jakllsch	Make this build without gpio(4).
1.20	27-Sep-2009	jakllsch	gpio(4) support for Intel ICH southbridges. Tested on Intel SS4200-E (ICH7), and Acorp 6A815EPD (ICH2) motherboards, on amd64 and i386 ports respectively. It should be noted that the majority of boards with ICH chips do not expose the GPIO pins for off-board use. For instance, aside from the three exposed-on-a-header pins on the 6A815EPD, another pin is also used to control write protect on the FWH. The SS4200 exposes the GPIO on a header that connects to the 10 LEDs on the front panel, as well as a tact switch on the back panel.
1.19	18-Aug-2009	dyoung	Let us detach ichlpcib(4) and its children. XXX More testing is needed. I've tested this on a Dell Dimension 3000, XXX but that system does not attach every possible device that I try to XXX detach with this code: ichlpcib0 at pci0 dev 31 function 0 ichlpcib0: vendor 0x8086 product 0x24d0 (rev. 0x02) timecounter: Timecounter "ichlpcib0" frequency 3579545 Hz quality 1000 ichlpcib0: 24-bit timer ichlpcib0: TCO (watchdog) timer configured. isa0 at ichlpcib0
1.18	11-Aug-2009	bouyer	Fix watchdog code: - the timer bound constants are in tick, so convert period to tick before checking it against the bounds - for ICH5 or older, fix code that would have always written a 0 period to the register.
1.17	29-Apr-2009	njoly	Attach 82801IEM LPC Interface Bridge too.
1.16	04-Apr-2009	joerg	Restore SpeedStep settings on shutdown. Some BIOSes don't like it, if SpeedStep is enabled and powerdown fails otherwise. Fixes PR kern/40487.

1.13	14-Aug-2008	yamt	revert some parts of the following commit. (given that it reverted other developers' changes saying "misc/cosmetic changes", i assume that it was unintentional.) this makes a watchdog on my box (8086:24d0) work again. ---------------------------- revision 1.1 date: 2007/08/26 16:49:47; author: xtraeme; state: Exp; branches: 1.1.2; Some changes for the ichlpcib driver: - Moved to x86/pci, so that EM64T systems running NetBSD/amd64 can use it. - Added support for the TCO on ICH6 or newer chipsets, adapted from FreeBSD. - Added timecounter support for the power management timer, adapted from OpenBSD. - Plus some misc/cosmetic changes. Thanks to yukonbob on irc@freenode for testing the TCO part on ICH4-M. Tested by me with ICH7 too.

1.5	23-Nov-2007	xtraeme	branches: 1.5.2; 1.5.4; tcotimer_setmode: convert seconds to ticks after the value has been checked with the limits. We can use now the max timeout value on ICH6 or newer (i.e 613 seconds and not the half of it as previously).
1.4	03-Sep-2007	xtraeme	branches: 1.4.2; 1.4.4; 1.4.6; 1.4.10; 1.4.14; Improve some comments.
1.3	01-Sep-2007	ober	Attach to ICH8M LPC. Tested watchdog and it works. ok xtraeme@
1.2	29-Aug-2007	xtraeme	Attach to the ICH9 LPC Interface Bridges. The datasheet doesn't mention any difference in the TCO part (compared to ICH[678]).

1.4.6.15	12-Nov-2007	joerg	GC unused softc field.
1.4.6.14	06-Nov-2007	joerg	Refactor PNP API: - Make suspend/resume directly a device functionality. It consists of three layers (class logic, device logic, bus logic), all of them being optional. This replaces D0/D3 transitions. - device_is_active returns true if the device was not disabled and was not suspended (even partially), device_is_enabled returns true if the device was enabled. - Change pnp_global_transition into pnp_system_suspend and pnp_system_resume. Before running any suspend/resume handlers, check that all currently attached devices support power management and bail out otherwise. The latter is not done for the shutdown/panic case. - Make the former bus-specific generic network handlers a class handler. - Make PNP message like volume up/down/toogle PNP events. Each device can register what events they are interested in and whether the handler should be global or not. - Introduce device_active API for devices to mark themselve in use from either the system or the device. Use this to implement the idle handling for audio and input devices. This is intended to replace most ad-hoc watchdogs as well. - Fix somes situations in which audio resume would lose mixer settings. - Make USB host controllers better deal with suspend in the light of shared interrupts. - Flush filesystem cache on suspend. - Flush disk caches on suspend. Put ATA disks into standby on suspend as well. - Adopt drivers to use the new PNP API. - Fix a critical bug in the generic cardbus layer that made D0->D3 break. - Fix ral(4) to set if_stop. - Convert cbb(4) to the new PNP API. - Apply the PCI Express SCI fix on resume again.
1.4.6.13	01-Oct-2007	joerg	Extend device API by device_power_private and device_power_set_private. The latter is a temporary mean until the pnp_register API itself is overhault. This functions allow a generic power handler to store its state independent of the driver. Use this and revamp the PCI power handling. Pretty much all PCI devices had power handlers that did the same thing, generalize this in pci_generic_power_register/deregister and the handler. This interface offers callbacks for the drivers to save and restore state on transistions. After a long discussion with jmcneill@ it was considered to be powerful enough until evidence is shown that devices can handle D1/D2 with less code and higher speed than without the full save/restore. The generic code is carefully written to handle device without PCI-PM support and ensure that the correct registers are written to when D3 loses all state. Reimplement the generic PCI network device handling on top of PCI generic power handling. Introduce pci_disable_retry as used and implemented locally at least by ath(4) and iwi(4). Use it in this drivers to restore behaviour from before the introduction of generic PCI network handling. Convert all PCI drivers that were using pnp_register to the new framework. The only exception is vga(4) as it is commonly used as console device. Add a note therein that this should be fixed later.

1.4.6.6	05-Sep-2007	joerg	Push the mapping of the HPET register window into the attach function. This should prevent DIAGNOSTIC from complaining when hpet is attached via ACPI.
1.4.6.5	04-Sep-2007	joerg	Don't use a global variable to decide whether this is a ICH6+, use a variable in the softc to determine whether the RCBA is supported. Add generic HPET support for ICH5 and ICH6+. This is not (yet) enabled by default, until someone adds the code to not use the direct attachment if hpet was configured via ACPI.

The GPIO lines on an ICH are usually connected to opaque platform- defined functionality, and may be manipulated by the ACPI DSDT or other mechanisms behind our backs. In one instance, it was found this in combiation with gpio_resume() sabotaged repeated suspend/resume cycles. GPIO functionality can be enabled by setting ichlpcib_gpio_disable to 0, for instance with `gdb -write`.

1.43.4.2	26-Jan-2015	martin	Pull up following revision(s) (requested by msaitoh in ticket #455): sys/arch/x86/pci/ichlpcib.c: revision 1.46 The PMBASE and GPIOBASE registers are not compatible with the PCI spec and the map sizes are fixed to 128bytes. The pci_mapreg_submap() function has a code to check the range of the BAR. The PCI_MAPREG_IO_SIZE() macro returns lower than 128bytes on some machines. This makes it impossible to use pci_mapreg_submap(). Use pci_conf_read() and bus_space_map() directly.
1.43.4.1	08-Jan-2015	martin	Pull up following revision(s) (requested by msaitoh in ticket #394): sys/dev/pci/pcivar.h: revision 1.101 sys/dev/pci/pci_map.c: revision 1.32 sys/dev/ic/i82801lpcreg.h: revision 1.12 sys/arch/x86/pci/ichlpcib.c: revision 1.45 Fix a bug that ichlpcib(4) maps I/O area incorrectly and then fails to attach gpio. It might also fix ACPI related problem described in PR#48960: - The LPCIB_PCI_PMBASE and LPCIB_PCI_GPIO register are alike PCI BAR but not completely compatible with it. It's ok because the registers' addresses are out of BAR0-BAR5(0x10-0x24) and are located in the device-dependent header. The PMBASE and GPIO registers define the base address and the type but not describe the size. The size is fixed to 128bytes. So use pci_mapreg_submap(). - Make pci_mapreg_submap() extern again. - Fix the calculation of the map size in pci_mapreg_submap().

TCO (`Total Cost of Ownership', Intel's bizarre name for a watchdog timer) used to hang off the Intel I/O platform controller hub's (ICH) low-pin-count interface bridge (LPC IB), or ichlpcib(4). On newer devices, it hangs off the ICH SMBus instead. Tested on INTEL 100SERIES_SMB (works) and INTEL 100SERIES_LP_SMB (doesn't work, still not sure why). XXX kernel revbump: This breaks the module ABI -- tco(4) modules older than the change to make ta_has_rcba into ta_version will incorrectly attach at buses they do not understand. (However, the tco(4) driver is statically built into GENERIC, so maybe it's safe for pullup since the module wouldn't have worked anyway.)

1.59	24-Mar-2020	knakahara	fix vmx(4) cannot link up at boot time. reviewed by msaitoh@n.o, thanks. vmx(4) could call if_link_state_change(ifp, LINK_STATE_UP) from vmxnet3_init() before ifp->if_link_cansched was set, because dp->dom_if_up() (in6_if_up() for INET6) could call ifp->if_init(). And then, workqueue_enqueue() was not called at that time. As the result, the last LQ_ITEM was stuck LINK_STATE_UP, so if_link_state_change_work_schedule() was never called until if_link_state_change(ifp, LINK_STATE_DOWN) was called. To fix this issue, vmx(4) avoid calling if_link_state_change() before ifp->if_link_cansched is set.
1.58	15-Mar-2020	thorpej	Define and implement a locking protocol for the ifmedia / mii layers: - MP-safe drivers provide a mutex to ifmedia that is used to serialize access to media-related structures / hardware regsiters. Converted drivers use the new ifmedia_init_with_lock() function for this. The new name is provided to ease the transition. - Un-converted drivers continue to call ifmedia_init(), which will supply a compatibility lock to be used instead. Several media-related entry points must be aware of this compatibility lock, and are able to acquire it recursively a limited number of times, if needed. This is a SPIN mutex with priority IPL_NET. - This same lock is used to serialize access to PHY registers and other MII-related data structures. The PHY drivers are modified to acquire and release the lock, as needed, and assert the lock is held as a diagnostic aid. The "usbnet" framework has had an overhaul of its internal locking protocols to fit in with the media / mii changes, and the drivers adapted. USB wifi drivers have been changed to provide their own adaptive mutex to the ifmedia later via a new ieee80211_media_init_with_lock() function. This is required because the USB drivers need an adaptive mutex. Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv. mcx also now calls ifmedia_init_with_lock() because it needs to also use an adaptive mutex. The mcx driver still needs to be fully converted to NET_MPSAFE.

1.15	28-Dec-2016	ozaki-r	Protect ec_multi* with mutex The data can be accessed from sysctl, ioctl, interface watchdog (if_slowtimo) and interrupt handlers. We need to protect the data against parallel accesses from them. Currently the mutex is applied to some drivers, we need to apply it to all drivers in the future. Note that the mutex is adaptive one for ease of implementation but some drivers access the data in interrupt context so we cannot apply the mutex to every drivers as is. We have two options: one is to replace the mutex with a spin one, which requires some additional works (see ether_multicast_sysctl), and the other is to modify the drivers to access the data not in interrupt context somehow.
1.14	27-Dec-2016	hikaru	Use the correct number of multicast addrs
1.13	15-Dec-2016	ozaki-r	Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input The benefits of the change are: - We can reduce codes - We can provide the same behavior between drivers - Where/When if_ipackets is counted up - Note that some drivers still update packet statistics in their own way (periodical update) - Moved bpf_mtap run in softint - This makes it easy to MP-ify bpf Proposed on tech-kern and tech-net

1.7	10-Jun-2016	ozaki-r	branches: 1.7.2; Introduce m_set_rcvif and m_reset_rcvif The API is used to set (or reset) a received interface of a mbuf. They are counterpart of m_get_rcvif, which will come in another commit, hide internal of rcvif operation, and reduce the diff of the upcoming change. No functional change.
1.6	09-Feb-2016	ozaki-r	Introduce softint-based if_input This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work.

1.1	10-Dec-2017	bouyer	Add support for I2C designware controllers (as found in Intel PCH devices), with a pci front-end. The pci front-end is tied to ACPI and Intel-specific, so it's in arch/x86/pci and not dev/pci. Core driver from OpenBSD, PCI front-end by me.
1.27	24-May-2022	bouyer	- msipic_construct_msix_pic(): set mp_table_base to memaddr (without table_offset), this is what Xen wants while there use pci_conf_write16() in msi_set_msictl_enablebit() too, for consistency (it seems that Xen accepts the 32bit write at this point, but this may change). - xen_map_msix_pirq(): don't forget to set map_irq.table_base in the MSI-X case, otherwise Xen maps it as MSI - call pic_hwunmask() after pirq_establish() in msi/msix case, to make sure the msi-x vector is unmasked. Now MSI-X works with Xen so stop disabling it in pci_attach_hook().
1.26	23-May-2022	bouyer	Work in progress on MSI/MSI-X on Xen (MSI works on my hardware, more work needed for MSI-X): - Xen silently rejects 32 bits writes to MSI configuration registers (especially when setting PCI_MSI_CTL_MSI_ENABLE/PCI_MSIX_CTL_ENABLE), it expects 16 bits writes. So introduce a pci_conf_write16(), only available on XENPV (and working only for mode 1 without PCI_OVERRIDE_CONF_WRITE) and use it to enable MSI or MSI-X on XENPV. - for multi-MSI vectors, Xen allocates all of them in a single hypercall, so it's not convenient to do it at intr_establish() time. So do it at alloc() time and register the pirqs in the msipic structure. xen_pic_to_gsi() now just returns the values cached in the msipic. As a bonus, if the PHYSDEVOP_map_pirq hypercall fails we can fail the alloc() and we don't need the xen_pci_msi*_probe() hacks. options NO_PCI_MSI_MSIX still on by default for XEN3_DOM0.
1.25	11-Dec-2020	knakahara	Fix build failure when XNEPV is defined.
1.24	11-Dec-2020	knakahara	Not pic->pic_addroute but pic->pic_hwunmask should enable interrupts for MSI-X. pic->pic_addroute should not enable interrupt, because callers expect interrupts have been disabled until they call pic->pic_hwunmask. By the way, the old implement writes zero to Vector Control for MSI-X Table Entries, howerver it must be read and updated. Because, there are not only Mask Bit but also ST lower and ST upper.
1.23	04-May-2020	jdolecek	branches: 1.23.2; add support for using MSI for XenPV Dom0 use PHYSDEVOP_map_pirq to get the pirq/gsi for MSI/MSI-X, switch also INTx to use it instead of PHYSDEVOP_alloc_irq_vector MSI confirmed working with single-vector MSI for wm(4), ahcisata(4), bge(4) XXX added some provision for MSI-X, but it doesn't actually work (no interrupts delivered), needs some further investigation; disable MSI-X for XENPV via flag in x86/pci/pci_machdep.c

1.20	02-Dec-2019	msaitoh	branches: 1.20.6; Use PCI_MSIX_"TBL"BIR_MASK instead of PCI_MSIX_"PBA"BIR_MASK for MSI-X table. This is not a real bug because both macros have the same value.

1.9	23-May-2017	nonaka	x86: Add preliminary x2APIC support. x2APIC is used only when x2APIC is enabled in BIOS/UEFI. LAPIC ID is not supported above 256.
1.8	17-Nov-2015	msaitoh	No functional change: - Add comments. - Remove obsolete comment. - Move definitions to better location. - Rename bit definition. - KNF. - Indent.
1.7	13-Aug-2015	msaitoh	Add workaround for PCI prefetchable bit in msipic_construct_msix_pic(). Some chips (e.g. Intel 82599) report SERR and MSI-X interrupt doesn't work. This problem might not be the driver's bug but our PCI common part or VMs' bug. See fxp(4), bge(4) and ixgbe(4). All of them has the same workaround related to prefetchable bit. For the MSI-X table area, it should not have side effect by prefetching. Until we find a real reason, we ignore the prefetchable bit.
1.6	13-Aug-2015	msaitoh	- Don't take pci_attach_args as an argument in pci_msi[x]_count(). - Move prototypes of pci_msi[x]_count() from x86/x86/pci_machdep_common to sys/dev/pci/pcivar.h. - Move pci_msi[x]_count() from x86/pci/pci_msi_machdep.c to sys/dev/pci/pci.c

1.37	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.36	24-Apr-2021	thorpej	branches: 1.36.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

XXX The amdtemp device currently does not seem to provide correct sensor values. XXX The amdnb_misc device does not currently have a rescan capability, so the amdtemp module will not instantiate any devices (PR kern/45268 reappears). XXX The agp attachment at the same pci device and function (which was the motivation for attaching amdtemp at pchb) probably ought to also be moved to attach at amdnb_miscbus.
1.33	30-Jan-2012	drochner	Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive} where it looks straightforward, and pci_aprint_devinfo_fancy in a few others where drivers want to supply their own device names instead of the pcidevs generated one. More complicated cases, where names are composed at runtime, are left alone for now. It certainly makes sense to simplify the drivers here rather than inventing a catch-all API. This should serve as as example for new drivers, and also ensure consistent output in the AB_QUIET ("boot -q") case. Also, it avoids excessive stack usage where drivers attach child devices because the buffer for the device name is not kept on the local stack anymore.
1.32	20-Aug-2011	jakllsch	branches: 1.32.2; 1.32.6; Add rescan support for 'amdtempbus' to x86 pchb(4). Maybe finally fixes PR#45268.

Correct that. Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names consistent with the other PCI flags and poisoning 3rd-party driver sources that use the flags in the old bad way.

1.22	16-Jun-2010	riz	Add AGP support for a number of Intel onboard devices, including 82G41, 82B43, E7221, 82965GME, and "Iron Lake". Device types (i915, i965, G33, and G4X variants) from the Linux Intel AGP driver, and (for 82G41) from Henry Bent in PR#42906. There are a few more varieties that should be relatively low-hanging fruit ("Pineview" and "Sandy Bridge"), but will require a little bit of rejiggering of the "chiptype". OK mrg@
1.21	24-Feb-2010	dyoung	branches: 1.21.2; A pointer typedef entails trading too much flexibility to declare const and non-const types, and the kernel uses both const and non-const PMF qualifiers and device suspensors, so change the pmf_qual_t and device_suspensor_t typedefs from "pointers to const" to non-pointer, non-const types.
1.20	08-Jan-2010	dyoung	branches: 1.20.2; Expand PMF_FN_* macros.

1.1	26-Oct-2007	xtraeme	branches: 1.1.2; 1.1.4; - Share pchb(4) between i386 and amd64; one copy is enough for both. - Move some of the x86 PCI devices into x86/pci/files.pci. - Add more x86 stuff into x86/conf/files.x86. ok joerg.
1.1.4.7	08-Dec-2007	jmcneill	Rename pnp(9) -> pmf(9), as requested by many.
1.1.4.6	27-Nov-2007	joerg	Sync with HEAD. amd64 Xen support needs testing.
1.1.4.5	06-Nov-2007	joerg	Refactor PNP API: - Make suspend/resume directly a device functionality. It consists of three layers (class logic, device logic, bus logic), all of them being optional. This replaces D0/D3 transitions. - device_is_active returns true if the device was not disabled and was not suspended (even partially), device_is_enabled returns true if the device was enabled. - Change pnp_global_transition into pnp_system_suspend and pnp_system_resume. Before running any suspend/resume handlers, check that all currently attached devices support power management and bail out otherwise. The latter is not done for the shutdown/panic case. - Make the former bus-specific generic network handlers a class handler. - Make PNP message like volume up/down/toogle PNP events. Each device can register what events they are interested in and whether the handler should be global or not. - Introduce device_active API for devices to mark themselve in use from either the system or the device. Use this to implement the idle handling for audio and input devices. This is intended to replace most ad-hoc watchdogs as well. - Fix somes situations in which audio resume would lose mixer settings. - Make USB host controllers better deal with suspend in the light of shared interrupts. - Flush filesystem cache on suspend. - Flush disk caches on suspend. Put ATA disks into standby on suspend as well. - Adopt drivers to use the new PNP API. - Fix a critical bug in the generic cardbus layer that made D0->D3 break. - Fix ral(4) to set if_stop. - Convert cbb(4) to the new PNP API. - Apply the PCI Express SCI fix on resume again.

1.6	17-Oct-2007	garbled	branches: 1.6.2; 1.6.8; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.5	16-Oct-2007	joerg	Make the check for a working RNG a bit more aggressive. Try to read 10 samples and bail out if there was a timeout to get either of those within 10ms or if they are all 0xff. Both are good indicators of a missing RNG.
1.4	16-Oct-2007	joerg	Exploit that only Intel devices are matched and all devices do the same. This saves two levels of indentation for the main body, making it more readable. Don't hide the error for disabling the RNG under DIAGNOSTIC, verbose is enough. Use aprint_*_dev.

1.49	11-Feb-2019	cherry	We reorganise definitions for XEN source support as follows: XEN - common sources required for baseline XEN support. XENPV - sources required for support of XEN in PV mode. XENPVHVM - sources required for support for XEN in HVM mode. XENPVH - sources required for support for XEN in PVH mode.

1.47	27-Nov-2018	jdolecek	actually allow pci_intr_alloc() with NULL count with MSI-X
1.46	27-Nov-2018	jdolecek	make pci_intr_alloc() try also MSI-X by default (with NULL count); there are boards/emulators which only have MSI-X and no MSI, and so far there is no evidence there are devices which support both and don't work in MSI-X mode this change is supposed to reduce amount of needed cut&paste code in drivers discussed briefly with jmcneill@
1.45	23-Sep-2018	cherry	Revert: http://mail-index.netbsd.org/source-changes/2018/09/10/msg098995.html It is incorrect to infer semantics from usage. the problem for which the original commit was intended should be fixed within the callee intr_establish_xname() and not the caller: pci_intr_find_intx_irq() This was accomplished via: http://mail-index.netbsd.org/source-changes/2018/09/20/msg099286.html
1.44	10-Sep-2018	cherry	In the NIOAPIC case, we do not need to support "legacy" irqs, ie; We don't need to simultaneously pass back the irq in the range 0 < irq < 16 (which are sometimes described as "legacy" in src This was non-obvious, until the semantics of "legacy" were used in inconsistent ways in Xen (to also mean interrupts in the 0 < irq < 256 range) which causes problems with attempting to unify the sys/arch/x86/isa/isa_machdep.c:isa_intr_establish_xname() function between XEN and !XEN This commit should not affect current functionality on any either native or Xen. It is needed for future code reorg, and published now as a preview.
1.43	24-Jun-2018	jdolecek	branches: 1.43.2; provide pci_intr_establish_xname() on x86 independantly from MSI, so it's available on XEN too; change also the stub to use weak symbol instead #ifdef

1.38	11-Jul-2016	knakahara	branches: 1.38.2; pci_intr_type() is required pci_chipset_tag_t argument by other than x86. pointed out by nonaka@n.o.

1.23	29-Aug-2011	dyoung	branches: 1.23.2; Use a loop instead of tail-recursion for the pci_intr(9) overrides. This is the same change that I just made to the pci(9) overrides. While I am here, fix a bug: use PCI_OVERRIDE_INTR_DISESTABLISH instead of PCI_OVERRIDE_INTR_ESTABLISH for the pci_intr_disestablish(9) override.
1.22	17-Aug-2011	dyoung	In pci_msi_establish(), replace several anonymous constants with IOAPIC_ symbols. No change in the generated assembly.
1.21	17-Aug-2011	dyoung	Redefine PCI_MSI_* and PCI_PCIE_* constants in terms of bits(3). Use named constants and more conventional variable names in pci_msi_establish() and pci_msi_disestablish(). Fix a couple of bugs: pci_msi_establish() returned a pointer to the struct intrhand instead of to the struct msi_hdl as it was intended to, and pci_msi_disestablish() did not free(9) the msi_hdl.
1.20	01-Aug-2011	drochner	add an experimental implementation of PCI MSIs (Message Signaled Interrupts). Successfully tested with hdaudio and "wpi" wireless ethernet. notes: -There seem to be buggy chips around which announce MSI support but don't correctly implement it. Thus the final word whether MSIs can be used should be by the driver. -Only a single vector is supported. For multiple vectors, the IDT allocation code would have to be changed. (And we would possibly run into problems due to the limited number of vectors supported by the current code.) -The code is "#if NIOAPIC > 0" because it uses the ioapic_edge interrupt stubs. These actually don't touch any ioapic, so this is somewhat a misnomer. -MSIs can't be identified by a "pin" but only by a cpu/vector pair. Common intr code soesn't deal well with this yet. -Drivers need to take care of saving/restoring MSI data in the device's config space on suspend/resume.
1.19	04-Apr-2011	dyoung	Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9), pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match predicate passed to pciide_compat_intr_establish() should ever modify their pci_attach_args argument, so make their pci_attach_args arguments const and deal with the fallout throughout the kernel. For the most part, these changes add a 'const' where there was no 'const' before, however, some drivers and MD code used to modify pci_attach_args. Now those drivers either copy their pci_attach_args and modify the copy, or refrain from modifying pci_attach_args: Xen: according to Manuel Bouyer, writing to pci_attach_args in pci_intr_map() was a leftover from Xen 2. Probably a bug. I stopped writing it. I have not tested this change. siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args. Probably a bug. I use a temporary variable. I have not tested this change. slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args. Probably a bug. Use a local pci_attach_args. I have not tested this change. viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the caller's pci_attach_args. Probably a bug. Make a local copy of the caller's pci_attach_args and modify the copy. I have not tested this change. While I'm here, make pci_mapreg_submap() static.

This change iterates on all devices on bus 0 to find the host bridge.

Now MSI-X works with Xen so stop disabling it in pci_attach_hook().
1.90	23-May-2022	bouyer	Work in progress on MSI/MSI-X on Xen (MSI works on my hardware, more work needed for MSI-X): - Xen silently rejects 32 bits writes to MSI configuration registers (especially when setting PCI_MSI_CTL_MSI_ENABLE/PCI_MSIX_CTL_ENABLE), it expects 16 bits writes. So introduce a pci_conf_write16(), only available on XENPV (and working only for mode 1 without PCI_OVERRIDE_CONF_WRITE) and use it to enable MSI or MSI-X on XENPV. - for multi-MSI vectors, Xen allocates all of them in a single hypercall, so it's not convenient to do it at intr_establish() time. So do it at alloc() time and register the pirqs in the msipic structure. xen_pic_to_gsi() now just returns the values cached in the msipic. As a bonus, if the PHYSDEVOP_map_pirq hypercall fails we can fail the alloc() and we don't need the xen_pci_msi*_probe() hacks. options NO_PCI_MSI_MSIX still on by default for XEN3_DOM0.

Let us think of the kernel operating the registers in two steps: 1) Select: enable configuration cycles and select a range of configuration-space addresses. 2) Access: read or write a word in PCI configuration space. To make the steps more explicit, extract some helper subroutines from pci_conf_read(9) and pci_conf_write(9): pci_conf_selector(tag, reg): from a pcitag_t and a register offset, create a word that enables configuration cycles and selects a configuration address range. pci_conf_select(w): for `w' a word created by pci_conf_selector(), enable configuration cycles and select the address range indicated by `w'. pci_conf_select(0): disable configuration cycles. pci_conf_port(tag, reg): map a pcitag_t and a register offset to an I/O port where the configuration access should occur.

TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.27	29-Aug-2007	dyoung	Use __arraycount().
1.26	22-Jul-2007	mjf	branches: 1.26.4; 1.26.6; Remove newline from format string of aprint_normal. Thanks to pooka@ for pointing it out.

1.24	19-Jul-2007	mjf	Change printf to aprintf_normal and add a newline as requested by Christoph Egger on port-xen.
1.23	09-Jul-2007	ad	branches: 1.23.2; 1.23.4; Merge some of the less invasive changes from the vmlocking branch: - kthread, callout, devsw API changes - select()/poll() improvements - miscellaneous MT safety improvements
1.22	22-Feb-2007	matt	branches: 1.22.4; 1.22.6; 1.22.12; Add missing initializer for _tag_needs_count
1.21	21-Feb-2007	mrg	add a pair of new bus_dma(9) functions: int _bus_dmatag_subregion(bus_dma_tag_t tag, bus_addr_t min_addr, bus_addr_t max_addr, bus_dma_tag_t *newtag, int flags) void _bus_dmatag_destroy(bus_dma_tag_t tag) that allow a (normally broken/limited) device to restrict the bus address range it can talk to. this is used by bce(4) to limit DMA addresses to 1GB range, the maximum the chip can address. all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several people on tech-kern. XXX: bus_dma(9) needs an update still.
1.20	06-Feb-2007	jmcneill	branches: 1.20.2; On Xbox, disallow pci_conf_read/pci_conf_write calls for bus 0 device 0 functions 1 and 2.

1.18	16-Nov-2006	christos	__unused removal on arguments; approved by core.
1.17	12-Oct-2006	christos	- sprinkle __unused on function decls. - fix a couple of unused bugs - no more -Wno-unused for i386
1.16	04-Jul-2006	christos	branches: 1.16.4; 1.16.6; Apply fvdl's acpi pci interrupt configuration code. - MPACPI is no more. - MPACPI_SCANPCI -> ACPI_SCANPCI
1.15	25-Jun-2006	soren	Add quirk for the not quite standard PCI bus in Parallels Desktop for Mac.
1.14	07-Feb-2006	bouyer	branches: 1.14.2; 1.14.10; Add back proper MPBIOS/MPACPI handling.
1.13	03-Feb-2006	bouyer	branches: 1.13.2; Split move interrupt-related PCI functions from pci_machdep.c to pci_intr_machdep.c. In Xen-3 registers access is done the normal way but interrupts need custom setup. Proposed on port-amd64, port-i386 and port-xen a week ago.
1.12	16-Nov-2005	christos	branches: 1.12.2; 1.12.4; PR/31885: Stephane Witzmann: Force pci mode 1 on SIS 741.
1.11	20-Jun-2005	sekiya	branches: 1.11.2; 1.11.8; pci_device_foreach(), pci_device_foreach_min(), pci_bridge_foreach(), and pci_bridge_hook don't actually have any dependancies on PCIBIOS-specific code, and they can be used to fixup PCI bus numbering in the absence of the BIOS. To that end, decouple them from PCIBIOS.
1.10	16-Apr-2005	yamt	tweak x86 bus_dma code so that it can be used by xen port. - distinguish paddr_t and bus_addr_t. for xen, use bus_addr_t in the sense of machine address. - move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h. - remove special handling of xen_shm. we can always grab machine address from pte.
1.9	30-Oct-2003	fvdl	branches: 1.9.8; 1.9.14; * keep track of PCI buses that aren't known by firmware, but are found by NetBSD * use this info in in intr_find_mpmapping * get rid of the last argument to intr_find_mpmapping, it was redundant
1.8	16-Oct-2003	fvdl	Add hooks and structures to allow the MP table intr mapping code a better shot at finding a mapping. For PCI interrupts, if a bus has no mappings, try its parent, with the swizzled pin, and the bridge's device number.
1.7	06-Sep-2003	fvdl	Move the bulk of pci_intr_string into a seperate intr_string function. Use that new function to print the pciide compat interrupt in pciide_machdep.c. Share pciide_machdep.c between amd64 and i386.
1.6	06-Sep-2003	fvdl	If possible, put the device name of the APIC used into the interrupt string, not "apic N". This makes it easier to match vmstat output with dmesg output.
1.5	15-Jun-2003	fvdl	branches: 1.5.2; Handle 64bit DMA addresses on PCI for platforms that can (currently only enabled on amd64). Add a dmat64 field to various PCI attach structures, and pass it down where needed. Implement a simple new function called pci_dma64_available(pa) to test if 64bit DMA addresses may be used. This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>, and there is more than 4G of memory.
1.4	29-May-2003	fvdl	Add the options MPBIOS_SCANPCI and MPACPI_SCANPCI to configure PCI roots with the MPBIOS/ACPI bus information, by walking through the buses, and descending down every bus that hasn't been marked configured yet.
1.3	07-May-2003	fvdl	Generalize bounce buffers, and use them for 32 bit PCI if needed. Make ALLOCNOW the default iff bouncing might be needed (this has no effect on i386 because ISA DMA devices already had to use ALLOCNOW, and PCI isn't bounced (yet), since we don't do > 4G at this point for i386.
1.2	28-Apr-2003	fvdl	Include "eisa.h" in order to get the NEISA value; without it EISA-only MP intr routing tables wouldn't be searched.
1.1	27-Feb-2003	fvdl	Moved here from i386/pci.

Support non-VGA framebuffers for Xen dom0. This is mandatory for graphic console on EFI-only hardware. Add a xen_genfb_getbtinfo() function which will return a btinfo_framebuffer structure, filled in with parameters provided by Xen when runing as a Xen dom0, call xen_genfb_getbtinfo() instead of lookup_bootinfo(BTINFO_FRAMEBUFFER) when adding properties to the PCI graphic device (when genfb is attached) and in x86_genfb_init() when genfb is used as console. x86/x86/consinit.c: If running as a Xen dom0, use xen_genfb_getbtinfo() to check if we have a genfb console xen/x86/consinit.c: support genfb as possible console xen/x86/consinit.c: use the hypervior IO as console until a better one is found. If the hypervisor is using a serial port for boot messages, we'll get NetBSD's boot message on the serial port too until the real console takes over. xen/x86/autoconf.c: rework device_register() to be closer to the x86 version. Especially make sure that device_pci_register() is called. Make sure to always fall back to xen_early_console, even for dom0 Enable genfb in DOM0 kernels Add ext_lfb_base to dom0_vga_console_info, from recent Xen. We know if it's present or not by checking dom0.info_size Add XENPF_get_dom0_console, which gets a dom0_vga_console_info stucture from the hypervisor. To be used by PVH dom0 kernels. XENPVH option is not used. Fix consinit.c to use XENPVHVM as intended and XENPVH from defflag for a dom0 PVH, the dom0_vga_console_info structure has to be retrieved using a platform hypercall; do so in the XENPVHVM case. Now genfb works in a PVH dom0 running on Xen 4.18 (Xen 4.15 doesn't support this platoform op, so no way to make it work here).

1.17	23-May-2022	bouyer	Work in progress on MSI/MSI-X on Xen (MSI works on my hardware, more work needed for MSI-X): - Xen silently rejects 32 bits writes to MSI configuration registers (especially when setting PCI_MSI_CTL_MSI_ENABLE/PCI_MSIX_CTL_ENABLE), it expects 16 bits writes. So introduce a pci_conf_write16(), only available on XENPV (and working only for mode 1 without PCI_OVERRIDE_CONF_WRITE) and use it to enable MSI or MSI-X on XENPV. - for multi-MSI vectors, Xen allocates all of them in a single hypercall, so it's not convenient to do it at intr_establish() time. So do it at alloc() time and register the pirqs in the msipic structure. xen_pic_to_gsi() now just returns the values cached in the msipic. As a bonus, if the PHYSDEVOP_map_pirq hypercall fails we can fail the alloc() and we don't need the xen_pci_msi*_probe() hacks. options NO_PCI_MSI_MSIX still on by default for XEN3_DOM0.

1.20	24-Apr-2021	thorpej	branches: 1.20.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.15	06-Apr-2012	plunky	device_pmf_is_registered() is not required
1.14	30-Jan-2012	drochner	Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive} where it looks straightforward, and pci_aprint_devinfo_fancy in a few others where drivers want to supply their own device names instead of the pcidevs generated one. More complicated cases, where names are composed at runtime, are left alone for now. It certainly makes sense to simplify the drivers here rather than inventing a catch-all API. This should serve as as example for new drivers, and also ensure consistent output in the AB_QUIET ("boot -q") case. Also, it avoids excessive stack usage where drivers attach child devices because the buffer for the device name is not kept on the local stack anymore.

For now, bus_space_tag's only member is bst_type, the type of space, which is either X86_BUS_SPACE_IO or X86_BUS_SPACE_MEM. In the future, new bus_space_tag members will refer to override-functions installed by a new function, bus_space_tag_create(9). Add pointers to constant struct bus_space_tag, x86_bus_space_io and x86_bus_space_mem. Use them to replace most uses of X86_BUS_SPACE_IO and X86_BUS_SPACE_MEM. Add an x86-specific bus_space_is_equal(9) implementation that compares the two tags' bst_type.

1.8	02-Apr-2009	dyoung	During shutdown, detach devices in an orderly fashion. Call the detach routine for every device in the device tree, starting with the leaves and moving toward the root, expecting that each (pseudo-)device driver will use the opportunity to gracefully commit outstandings transactions to the underlying (pseudo-)device and to relinquish control of the hardware to the system BIOS. Detaching devices is not suitable for every shutdown: in an emergency, or if the system state is inconsistent, we should resort to a fast, simple shutdown that uses only the pmf(9) shutdown hooks and the (deprecated) shutdownhooks. For now, if the flag RB_NOSYNC is set in boothowto, opt for the fast, simple shutdown. Add a device flag, DVF_DETACH_SHUTDOWN, that indicates by its presence that it is safe to detach a device during shutdown. Introduce macros CFATTACH_DECL3() and CFATTACH_DECL3_NEW() for creating autoconf attachments with default device flags. Add DVF_DETACH_SHUTDOWN to configuration attachments for atabus(4), atw(4) at cardbus(4), cardbus(4), cardslot(4), com(4) at isa(4), elanpar(4), elanpex(4), elansc(4), gpio(4), npx(4) at isa(4), nsphyter(4), pci(4), pcib(4), pcmcia(4), ppb(4), sip(4), wd(4), and wdc(4) at isa(4). Add a device-detachment "reason" flag, DETACH_SHUTDOWN, that tells the autoconf code and a device driver that the reason for detachment is system shutdown. Add a sysctl, kern.detachall, that tells the system to try to detach every device at shutdown, regardless of any device's DVF_DETACH_SHUTDOWN flag. The default for kern.detachall is 0. SET IT TO 1, PLEASE, TO HELP TEST AND DEBUG DEVICE DETACHMENT AT SHUTDOWN. This is a work in progress. In future work, I aim to treat pseudo-devices more thoroughly, and to gracefully tear down a stack of (pseudo-)disk drivers and filesystems, including cgd(4), vnd(4), and raid(4) instances at shutdown. Also commit some changes that are not easily untangled from the rest: (1) begin to simplify device_t locking: rename struct pmf_private to device_lock, and incorporate device_lock into struct device. (2) #include <sys/device.h> in sys/pmf.h in order to get some definitions that it needs. Stop unnecessarily #including <sys/device.h> in sys/arch/x86/include/pic.h to keep the amd64, xen, and i386 releases building.

1.1.4.3	06-Nov-2007	joerg	Refactor PNP API: - Make suspend/resume directly a device functionality. It consists of three layers (class logic, device logic, bus logic), all of them being optional. This replaces D0/D3 transitions. - device_is_active returns true if the device was not disabled and was not suspended (even partially), device_is_enabled returns true if the device was enabled. - Change pnp_global_transition into pnp_system_suspend and pnp_system_resume. Before running any suspend/resume handlers, check that all currently attached devices support power management and bail out otherwise. The latter is not done for the shutdown/panic case. - Make the former bus-specific generic network handlers a class handler. - Make PNP message like volume up/down/toogle PNP events. Each device can register what events they are interested in and whether the handler should be global or not. - Introduce device_active API for devices to mark themselve in use from either the system or the device. Use this to implement the idle handling for audio and input devices. This is intended to replace most ad-hoc watchdogs as well. - Fix somes situations in which audio resume would lose mixer settings. - Make USB host controllers better deal with suspend in the light of shared interrupts. - Flush filesystem cache on suspend. - Flush disk caches on suspend. Put ATA disks into standby on suspend as well. - Adopt drivers to use the new PNP API. - Fix a critical bug in the generic cardbus layer that made D0->D3 break. - Fix ral(4) to set if_stop. - Convert cbb(4) to the new PNP API. - Apply the PCI Express SCI fix on resume again.

1.11	04-Apr-2011	dyoung	branches: 1.11.4; 1.11.14; 1.11.18; Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9), pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match predicate passed to pciide_compat_intr_establish() should ever modify their pci_attach_args argument, so make their pci_attach_args arguments const and deal with the fallout throughout the kernel. For the most part, these changes add a 'const' where there was no 'const' before, however, some drivers and MD code used to modify pci_attach_args. Now those drivers either copy their pci_attach_args and modify the copy, or refrain from modifying pci_attach_args: Xen: according to Manuel Bouyer, writing to pci_attach_args in pci_intr_map() was a leftover from Xen 2. Probably a bug. I stopped writing it. I have not tested this change. siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args. Probably a bug. I use a temporary variable. I have not tested this change. slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args. Probably a bug. Use a local pci_attach_args. I have not tested this change. viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the caller's pci_attach_args. Probably a bug. Make a local copy of the caller's pci_attach_args and modify the copy. I have not tested this change. While I'm here, make pci_mapreg_submap() static.

1.10	12-Apr-2023	riastradh	ichsmb(4), tco(4): Add support for TCO on newer Intel chipsets. TCO (`Total Cost of Ownership', Intel's bizarre name for a watchdog timer) used to hang off the Intel I/O platform controller hub's (ICH) low-pin-count interface bridge (LPC IB), or ichlpcib(4). On newer devices, it hangs off the ICH SMBus instead. Tested on INTEL 100SERIES_SMB (works) and INTEL 100SERIES_LP_SMB (doesn't work, still not sure why). XXX kernel revbump: This breaks the module ABI -- tco(4) modules older than the change to make ta_has_rcba into ta_version will incorrectly attach at buses they do not understand. (However, the tco(4) driver is statically built into GENERIC, so maybe it's safe for pullup since the module wouldn't have worked anyway.)
1.9	22-Sep-2022	riastradh	branches: 1.9.4; tco(4): Nix PMC_TCO_BASE offset in TCO register definitions. This just uses a subregion with PMC_TCO_BASE automatically applied. No functional change intended.
1.8	22-Sep-2022	riastradh	tco(4): Use a subregion of the PMC registers for TCO registers. This is an intermediate step that will let us decouple it from access via PMBASE.
1.7	22-Sep-2022	riastradh	ichlpcib(4), tco(4): Rename iot -> pmt, ioh -> pmh. Makes it clearer that this is specifically about the power management controller (PMC) registers relative to PMBASE.
1.6	22-Sep-2022	riastradh	ichlpcib(4), tco(4): Take `lpcib_' off various names. For PMC-specific ones, change `lpcib_' to `pmc_'. These are in a separate PCI device in newer chipsets. For TCO-specific ones, which may live in different places, whether at their own base address or as an offset from PMBASE, just leave it as `tco_' or `tcotimer'. No functional change intended.
1.5	22-Sep-2022	riastradh	tco(4): Rename lpcib_tco_attach_args -> tco_attach_args. No longer hangs off LPC bus, newer devices hang it off SMBus.
1.4	22-Sep-2022	riastradh	tco(4): Change has_rcba bit into version number. Will be useful for newer Intel platform controller hubs. No functional change intended. Module ABI is unchanged, although older modules will do something nonseneical when confronted with versions above 1 -- that will require a revbump (but with any luck, it will make life easier for versions above 2 easier once we do that).
1.3	21-Sep-2022	riastradh	tco(4): Fix whitespace. No functional change intended.

Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.2	15-Mar-2018	maya	branches: 1.2.6; 1.2.16; Provide a default case also when building imc as builtin. Fixes ALL kernel build. ok pgoyette.
1.1	01-Mar-2018	pgoyette	branches: 1.1.2; Move the imc(4) and imcsmb(4) sources into architecture-specific directory (for previous CVS history see the sys/dev/pci/imcsmb/ Attic)
1.1.2.1	22-Mar-2018	pgoyette	Synch with HEAD, resolve conflicts
1.2.16.2	28-Mar-2021	thorpej	- The third argument passed to the rescan function is a locs array, not a pointer to flags. - imc and imcsmb each carry only a single interface attribute, so no need to be explicit.
1.2.16.1	23-Mar-2021	thorpej	Convert config_found_ia() call sites where the device only carries a single interface attribute to bare config_found() calls.
1.2.6.1	11-Oct-2022	martin	Pull up following revision(s) (requested by msaitoh in ticket #1537): sys/arch/x86/pci/imcsmb/imc.c: revision 1.5 sys/dev/pci/pcidevs: revision 1.1461-1.1468 add several samsung nvme entries Add more Alder Lake devices. Jasper Lake Intel Trace Hub on Compute Die is not 0x4da6 but 0x4e29. Add Intel Core 8G (8core, H, Halo) Host Bridge, DRAM. Sort by number. No functional change. Add AMD 19h/6xh Root Complex. Add AMD FCH SATA Controller D add NVIDIA GeForce GTX 770 Fix compile error.
1.3.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
1.7	15-Sep-2025	thorpej	Encapsulate what's needed to attach an I2C bus into a iicbus_attach() inline.
1.6	10-May-2023	riastradh	x86/imc(4): Use config_detach_children.
1.5	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.4	24-Apr-2021	thorpej	branches: 1.4.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.3	22-Dec-2019	thorpej	branches: 1.3.10; Cleanup i2c bus acquire / release, centralizing all of the logic into iic_acquire_bus() / iic_release_bus(). "acquire" and "release" hooks no longer need to be provided by back-end controller drivers (only if they need special handling, e.g. powering on the i2c controller). This results in the removal of a bunch of rendundant code from each back-end controller driver. Assert that we are not in hard interrupt context in iic_acquire_bus(), iic_exec(), and iic_release_bus().
1.2	03-Mar-2018	pgoyette	branches: 1.2.4; Fix the attach message - needs a ": "
1.1	01-Mar-2018	pgoyette	Move the imc(4) and imcsmb(4) sources into architecture-specific directory (for previous CVS history see the sys/dev/pci/imcsmb/ Attic)
1.2.4.1	08-Apr-2020	martin	Merge changes from current as of 20200406
1.3.10.2	28-Mar-2021	thorpej	- The third argument passed to the rescan function is a locs array, not a pointer to flags. - imc and imcsmb each carry only a single interface attribute, so no need to be explicit.
1.3.10.1	23-Mar-2021	thorpej	In imcsmb_rescan(), no need to explcitly check that we're being asked to rescan on the "i2cbus" interface attribute. The autoconfiguration machinery will not request a rescan of an interface attribute that a device does not carry, and imcsmb only carries "i2cbus".
1.4.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
1.1	01-Mar-2018	pgoyette	Move the imc(4) and imcsmb(4) sources into architecture-specific directory (for previous CVS history see the sys/dev/pci/imcsmb/ Attic)
