1.5	14-Dec-2007	chris	Fix for PR cats/18026. cats was never able to dump a kernel core dump because reading from VGA addresses (0xb8000) was causing the system to hang. To workaround this reprogram the footbridge to map the memory to appear on the PCI bus at 0x20000000, rather than at 0x0. Also configure the pci bus to have a DMA range so that data is mapped correctly. Note that -current kernels seem to hang when unmounting the fs. This is a seperate issue, and appears to be because interrupts need to be enabled to unmount filesystems. So using reboot 0x104 does work, as it does a sync without unmounting the filesystems. Also arm savecore doesn't do anything with the memroy dump, as on arm we currently just dump the raw memory, there's no header block to indicate memory sizes or other useful information.

1.3	03-Nov-2002	chris	Checkin new interrupt handling code for the footbridge. This is based upon Jason's work on xscale. Most of the interrupt handling code is now written in C using an asm stub to call into the C code. spl* now only updates a software mask, and does not update the hardware, this should be much faster. The new code works well on cats, it's untested on netwinder, but should work. The code implements generic soft interrupts. More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future.
1.2	28-Sep-2002	chris	branches: 1.2.2; Interrupt 19 does actually do something: 19 PMCSR written by host (all to do with power management)

1.30	27-Sep-2022	skrll	Remove unnecessary sys/malloc.h include
1.29	13-Aug-2021	skrll	Trailing whitespace
1.28	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.27	24-Apr-2021	thorpej	branches: 1.27.8; 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?).
1.26	10-Oct-2012	skrll	branches: 1.26.52; Update comments to reflect the real function prototypes. From chuq.
1.25	01-Jul-2011	dyoung	branches: 1.25.2; 1.25.12; #include <sys/bus.h> instead of <machine/bus.h>.
1.24	17-May-2011	dyoung	PCI_FLAGS_IO_ENABLED and PCI_FLAGS_MEM_ENABLED changed their functional role in NetBSD (drivers are no longer supposed to write these to pa_flags) without changing name. 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. This patch produces no binary changes in this set of PCI kernels when they are compiled w/o 'options DIAGNOSTIC' and w/ -V MKREPRO=yes: algor P4032 P5064 P6032 alpha GENERIC amd64 GENERIC XEN3_DOM0 arc GENERIC atari HADES MILAN-PCIIDE bebox GENERIC cats GENERIC cobalt GENERIC evbarm-el ADI_BRH ARMADILLO9 CP3100 GEMINI GEMINI_MASTER GEMINI_SLAVE evbarm-el GUMSTIX HDL_G IMX31LITE INTEGRATOR IQ31244 IQ80310 IQ80321 evbarm-el IXDP425 IXM1200 KUROBOX_PRO evbarm-el LUBBOCK MARVELL_NAS NAPPI NSLU2 SHEEVAPLUG SMDK2800 TEAMASA_NPWR evbarm-el TEAMASA_NPWR_FC TS7200 TWINTAIL ZAO425 evbmips-el AP30 DBAU1500 DBAU1550 MALTA MERAKI MTX-1 OMSAL400 RB153 WGT624V3 evbmips64-el XLSATX evbppc EV64260 MPC8536DS MPC8548CDS OPENBLOCKS200 OPENBLOCKS266 evbppc OPENBLOCKS266_OPT P2020RDB PMPPC RB800 WALNUT hp700 GENERIC i386 ALL XEN3_DOM0 XEN3_DOMU ibmnws GENERIC iyonix GENERIC landisk GENERIC macppc GENERIC mvmeppc GENERIC netwinder GENERIC ofppc GENERIC prep GENERIC sandpoint GENERIC sbmips-el GENERIC sgimips GENERIC32_IP2x GENERIC32_IP3x sparc GENERIC_SUN4U KRUPS sparc64 GENERIC
1.23	18-Nov-2010	skrll	branches: 1.23.2; Comment KNF.
1.22	18-Nov-2010	skrll	Remove commented out setting of SDRAM_MEMORY_ADDR - it's set later on.
1.21	21-Jul-2009	skrll	branches: 1.21.4; device_t/softc split CFATTACH_DECL -> CFATTACH_DECL_NEW struct device * -> device_t struct cfdata * -> cfdata_t Use aprint*
1.20	14-Mar-2009	dsl	Change about 4500 of the K&R function definitions to ANSI ones. There are still about 1600 left, but they have ',' or /* ... */ in the actual variable definitions - which my awk script doesn't handle. There are also many that need () -> (void). (The script does handle misordered arguments.)
1.19	14-Mar-2009	dsl	Remove all the __P() from sys (excluding sys/dist) Diff checked with grep and MK1 eyeball. i386 and amd64 GENERIC and sys still build.

1.16	11-Dec-2005	christos	branches: 1.16.20; 1.16.24; merge ktrace-lwp.
1.15	30-Aug-2004	drochner	branches: 1.15.12; Phase out the use of a string as first "attach args" member to control which bustype should be attached with a specific call to config_found() (from a "mainbus" or a bus bridge). Do it for isa/eisa/mca and pci/agp for now. These buses all attach to an mi interface attribute "isabus", "eisabus" etc., and the autoconf framework now allows to specify an interface attribute on config_found() and config_search(), which limits the search of matching config data to these which attach to that specific attribute. So we basically have to call config_found_ia(..., "foobus", ...) where such a bus is attached. As a consequence, where a "mainbus" or alike also attaches other devices (eg CPUs) which do not attach to a specific attribute yet, we need at least pass an attribute name (different from "foobus") so that the foo bus is not found at these places. This made some minor changes necessary which are not obviously related to the mentioned buses.
1.14	15-Jun-2003	fvdl	branches: 1.14.2; 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.
1.13	23-Mar-2003	chris	Add __KERNEL_RCSID tags to footbridge files.
1.12	01-Jan-2003	thorpej	Use aprint_normal() for cfprint routines.

1.10	02-Oct-2002	thorpej	branches: 1.10.2; Use CFATTACH_DECL().
1.9	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.8	27-Sep-2002	provos	remove trailing \n in panic(). approved perry.
1.7	16-May-2002	thorpej	* Add "pcitag_t pba_bridgetag" to pci_attach_args. This is set to NULL for root PCI busses. For busses behind a bridge, it points to a persistent copy of the bridge's pcitag_t. This can be very useful for machine-dependent PCI bus enumeration code. Implement a machine-dependent pci_enumerate_bus() for sparc64 which uses OFW device nodes to enumerate the bus. When a PCI bus that is behind a bridge is attached, pci_attach_hook() allocates a new PCI chipset tag for the new bus and sets it's "curnode" to the OFW node of the bridge. This is used as a starting point when enumerating that bus. Root busses get the OFW node of the host bridge (psycho). * Garbage-collect "ofpci" and "ofppb" from the sparc64 port.
1.6	04-May-2002	chris	branches: 1.6.2; Implement a proper delay routine for footbridge based systems. Note that until the footbridge is attached we still have to rely on a loop. This uses TIMER_3 running at 100Hz. Sadly this doesn't appear to fix the tlp problems, which either means that this delay routine is not as accurate as it should/could be or tlp is still broken.
1.5	12-Apr-2002	thorpej	Centralize ARM CPU configuration information by adding a new header file, <arm/cpuconf.h>, which pulls in "opt_cputypes.h" and then defines the following: * CPU_NTYPES -- now many CPU types are configured into the kernel. What you really want to know is "== 1" or "> 1". * Defines ARM_ARCH_2, ARM_ARCH_3, ARM_ARCH_4, ARM_ARCH_5, depending on which ARM architecture versions are configured (based on CPU_* options). Also defines ARM_NARCH to determins how many architecture versions are configured. * Defines ARM_MMU_MEMC, ARM_MMU_GENERIC, ARM_MMU_XSCALE depending on which classes of ARM MMUs are configured into the kernel, and ARM_NMMUS to determine how many MMU classes are configured. Remove the needless inclusion of "opt_cputypes.h" in several places. Convert remaining users to <arm/cpuconf.h>.
1.4	05-Jan-2002	chris	Make some of the arm32 files build with LOOSE_PROTOTYPES not set in the makefile. Turned up a few mismatched functions. Note that this isn't all of the arm32 files. Aim will be to get arm32 kernels built with LOOSE_PROTOTYPES not set.
1.3	23-Nov-2001	thorpej	Use <arm/cpufunc.h>, not <machine/cpufunc.h>.
1.2	05-Sep-2001	matt	branches: 1.2.6; Change <machine/irqhandler.h> to <machine/intr.h> since the latter always includes the former and is a standard include file.

1.17.24.1	11-Aug-2007	chris	Initial check-in of reworked arm interrupt routines. Main things to note on this branch: * spl routines are inlined, less complex, and small (kernel drops in size) * interrupts are handled in priority order (for most things it doesn't matter, but pending ipls are used to determine if there is any work to do) * arm_irqhandler.c is derived from footbridge_irqhandler.c, which was based on work by thorpej. * The code tries to touch hardware as little as possible. * spl masks are no longer tracked, as the system is based on pending ipls The shared code uses global ipl lists to track which interrupt handlers are attached to which ipl (arm_iplq[]). Interrupt sources register with the common code to indicate: * how many irq lines they have * a function to set the hardware mask. * call arm_intr_claim and arm_intr_disestablish to setup handlers When an interrupt occurs the ipl is flagged as pending, in ipls_pending. If it can be handled at the current_ipl_level the code does so. If it can't be handled it's left until the current_ipl_level drops. As the ipl level changes down a quick test is made of the new ipl level against the ipls_pending value. If an ipl is pending arm_intr_splx_lifter is called to handle the pending ipls. It should be noted that all interrupts are left enabled at the hardware level, interrupts are only masked when they occur. They are only re-enabled after it's interrupt handler is called. Hardware masks are not changed at any other time. Soft interrupts are treated the same as hardware interrupts, they register as a provider, and do not get treated specially. All the soft interrupt handlers are placed onto the relevant global ipl queue, the same as hard interrupts handlers. At the moment only footbridge within a cats has been updated to use the new handling. Todo: * change the handling of interrupts, so that the hardware doesn't register a routine to fetch the hardware status. Instead is makes a call which provides the mask. This removes the primary flag when registering an interrupt provider. It also makes more sense with multiple interrupt sources. * Arm v5 has the clz asm, which could be used instead of the carefully hand rolled arm_intr_fls function. * switch cats isa support to use this framework. * switch iomd and acorn32 to use this framework. * switch shark to use this framework. * port any other arm platforms that are interested * examine overlaps between this code and ppcoea-renovation branch. * add support for different trigger types (Edge, level, pulse, etc) (note that iomd and shark currently touch hardware on every spl change, hence why they're targets to port)

1.1	05-Jan-2002	chris	branches: 1.1.2; 1.1.4; Make some of the arm32 files build with LOOSE_PROTOTYPES not set in the makefile. Turned up a few mismatched functions. Note that this isn't all of the arm32 files. Aim will be to get arm32 kernels built with LOOSE_PROTOTYPES not set.

1.25	20-Sep-2008	chris	Fix kernel boot issue on cats. The delay(9) loop, used before the clock device is probed and a hardware timer is available, was out by a factor of 625. This wasn't an issue until revision 1.45 of sys/dev/ic/pckbc.c which switched to using delay(9) when polling the keyboard controller. Cats attaches the console (and pckbc) before the clock has been probed, and so the delay loop code is used causing issue with the keyboard polling.
1.24	03-Dec-2007	ad	branches: 1.24.14; 1.24.18; 1.24.20; 1.24.24; Interrupt handling changes, in discussion since February: - Reduce available SPL levels for hardware devices to none, vm, sched, high. - Acquire kernel_lock only for interrupts at IPL_VM. - Implement threaded soft interrupts.

1.16	17-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.15	03-Nov-2002	chris	Checkin new interrupt handling code for the footbridge. This is based upon Jason's work on xscale. Most of the interrupt handling code is now written in C using an asm stub to call into the C code. spl* now only updates a software mask, and does not update the hardware, this should be much faster. The new code works well on cats, it's untested on netwinder, but should work. The code implements generic soft interrupts. More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future.
1.14	29-Oct-2002	tsutsui	Initialize statprev in setstatclockrate().
1.13	10-Oct-2002	chris	branches: 1.13.2; Fix thinko from this morning, delay is reentrant, so resetting the timer to 0 on entry will confuse any already running delay.
1.12	10-Oct-2002	chris	Minor tweaks to footbridge's delay, always reset the timer when starting delay run (and set last to the counter value). When the read value is 0, reset the timer (don't wait till the next loop round to reset it) Add a bit of debug to the calibration stuff to make sure its working ok.
1.11	05-Oct-2002	chris	Add random jitter to stat clock, the random jitter is +- 511 usec's, so we should average the nominal clock rate. stathz now runs at hz (the hard clock hz), without getting high amounts of time in interrupt handling.
1.10	02-Oct-2002	thorpej	Use CFATTACH_DECL().
1.9	28-Sep-2002	chris	Enable the use of a seperate statclock. Currently statclock runs at 64hz, maybe it should be faster or slower, I did try it being the same as hz, but that just made it look like we spent 10% of time handling interrupts, rather than the 3% that this gives. Also fix the IPL_LEVELS for netwinder.
1.8	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.7	27-Sep-2002	provos	remove trailing \n in panic(). approved perry.

1.25	17-Oct-2007	garbled	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	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.4	17-Mar-2002	atatat	branches: 1.4.4; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.

1.2	03-Nov-2002	chris	Checkin new interrupt handling code for the footbridge. This is based upon Jason's work on xscale. Most of the interrupt handling code is now written in C using an asm stub to call into the C code. spl* now only updates a software mask, and does not update the hardware, this should be much faster. The new code works well on cats, it's untested on netwinder, but should work. The code implements generic soft interrupts. More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future.
1.1	28-Sep-2002	chris	branches: 1.1.2; 1.1.4; 1.1.6; cats and netwinder can share a common footbridge_intr.h file, so install and share a common file.

1.10.20.3	18-Aug-2007	chris	Rework registration call, so that it no longer takes a status paramater. Rework dispatch routines, so no implicit ordering is required in the irq groups. This removes the primary flag, and also makes hardware dependant dispatch routines again. Update arm_intr_queue_irqs to disable interrupts. This is necessary when child buses are present, eg isa bus, as the isa interrupt handler is called with interrupts enabled, and I believe that the footbridge handler was trampling on the isa handler setting up pending flags. cats can now install using the update irq code (previously it would randomly hang)
1.10.20.2	12-Aug-2007	chris	Switch footbridge isa to use common code. This required changes to the arm code: * intr_claim now takes a type to indicate edge, level or pulse. It has isa level understanding of types and uses a callback to set the hardware type. * slightly adjust how pending interrupts are queued up. * switch the ICU setup code to make use the defines in i8259reg.h, rather than using magic numbers.
1.10.20.1	11-Aug-2007	chris	Initial check-in of reworked arm interrupt routines. Main things to note on this branch: * spl routines are inlined, less complex, and small (kernel drops in size) * interrupts are handled in priority order (for most things it doesn't matter, but pending ipls are used to determine if there is any work to do) * arm_irqhandler.c is derived from footbridge_irqhandler.c, which was based on work by thorpej. * The code tries to touch hardware as little as possible. * spl masks are no longer tracked, as the system is based on pending ipls The shared code uses global ipl lists to track which interrupt handlers are attached to which ipl (arm_iplq[]). Interrupt sources register with the common code to indicate: * how many irq lines they have * a function to set the hardware mask. * call arm_intr_claim and arm_intr_disestablish to setup handlers When an interrupt occurs the ipl is flagged as pending, in ipls_pending. If it can be handled at the current_ipl_level the code does so. If it can't be handled it's left until the current_ipl_level drops. As the ipl level changes down a quick test is made of the new ipl level against the ipls_pending value. If an ipl is pending arm_intr_splx_lifter is called to handle the pending ipls. It should be noted that all interrupts are left enabled at the hardware level, interrupts are only masked when they occur. They are only re-enabled after it's interrupt handler is called. Hardware masks are not changed at any other time. Soft interrupts are treated the same as hardware interrupts, they register as a provider, and do not get treated specially. All the soft interrupt handlers are placed onto the relevant global ipl queue, the same as hard interrupts handlers. At the moment only footbridge within a cats has been updated to use the new handling. Todo: * change the handling of interrupts, so that the hardware doesn't register a routine to fetch the hardware status. Instead is makes a call which provides the mask. This removes the primary flag when registering an interrupt provider. It also makes more sense with multiple interrupt sources. * Arm v5 has the clz asm, which could be used instead of the carefully hand rolled arm_intr_fls function. * switch cats isa support to use this framework. * switch iomd and acorn32 to use this framework. * switch shark to use this framework. * port any other arm platforms that are interested * examine overlaps between this code and ppcoea-renovation branch. * add support for different trigger types (Edge, level, pulse, etc) (note that iomd and shark currently touch hardware on every spl change, hence why they're targets to port)

1.4	03-Nov-2002	chris	Checkin new interrupt handling code for the footbridge. This is based upon Jason's work on xscale. Most of the interrupt handling code is now written in C using an asm stub to call into the C code. spl* now only updates a software mask, and does not update the hardware, this should be much faster. The new code works well on cats, it's untested on netwinder, but should work. The code implements generic soft interrupts. More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future.
1.3	14-Oct-2002	bjh21	branches: 1.3.2; Continue the " - . - 8" purge. Specifically: add rd, pc, #foo - . - 8 -> adr rd, foo ldr rd, [pc, #foo - . - 8] -> ldr rd, foo Also, when saving the return address for a function pointer call, use "mov lr, pc" just before the call unless the return address is somewhere other than just after the call site. Finally, a few obvious little micro-optimisations like using LDR directly rather than ADR followed by LDR, and loading directly into PC rather than bouncing via R0.
1.2	19-Aug-2001	matt	branches: 1.2.6; Change local offset/label for irqhandlers to Lirqhandlers. Because in ELF _C_LABEL(irqhandlers) == irqhandlers so we were getting self-referential pointer which causes the IRQ to fall on itself.

1.17.24.3	18-Aug-2007	chris	Rework registration call, so that it no longer takes a status paramater. Rework dispatch routines, so no implicit ordering is required in the irq groups. This removes the primary flag, and also makes hardware dependant dispatch routines again. Update arm_intr_queue_irqs to disable interrupts. This is necessary when child buses are present, eg isa bus, as the isa interrupt handler is called with interrupts enabled, and I believe that the footbridge handler was trampling on the isa handler setting up pending flags. cats can now install using the update irq code (previously it would randomly hang)
1.17.24.2	12-Aug-2007	chris	Switch footbridge isa to use common code. This required changes to the arm code: * intr_claim now takes a type to indicate edge, level or pulse. It has isa level understanding of types and uses a callback to set the hardware type. * slightly adjust how pending interrupts are queued up. * switch the ICU setup code to make use the defines in i8259reg.h, rather than using magic numbers.
1.17.24.1	11-Aug-2007	chris	Initial check-in of reworked arm interrupt routines. Main things to note on this branch: * spl routines are inlined, less complex, and small (kernel drops in size) * interrupts are handled in priority order (for most things it doesn't matter, but pending ipls are used to determine if there is any work to do) * arm_irqhandler.c is derived from footbridge_irqhandler.c, which was based on work by thorpej. * The code tries to touch hardware as little as possible. * spl masks are no longer tracked, as the system is based on pending ipls The shared code uses global ipl lists to track which interrupt handlers are attached to which ipl (arm_iplq[]). Interrupt sources register with the common code to indicate: * how many irq lines they have * a function to set the hardware mask. * call arm_intr_claim and arm_intr_disestablish to setup handlers When an interrupt occurs the ipl is flagged as pending, in ipls_pending. If it can be handled at the current_ipl_level the code does so. If it can't be handled it's left until the current_ipl_level drops. As the ipl level changes down a quick test is made of the new ipl level against the ipls_pending value. If an ipl is pending arm_intr_splx_lifter is called to handle the pending ipls. It should be noted that all interrupts are left enabled at the hardware level, interrupts are only masked when they occur. They are only re-enabled after it's interrupt handler is called. Hardware masks are not changed at any other time. Soft interrupts are treated the same as hardware interrupts, they register as a provider, and do not get treated specially. All the soft interrupt handlers are placed onto the relevant global ipl queue, the same as hard interrupts handlers. At the moment only footbridge within a cats has been updated to use the new handling. Todo: * change the handling of interrupts, so that the hardware doesn't register a routine to fetch the hardware status. Instead is makes a call which provides the mask. This removes the primary flag when registering an interrupt provider. It also makes more sense with multiple interrupt sources. * Arm v5 has the clz asm, which could be used instead of the carefully hand rolled arm_intr_fls function. * switch cats isa support to use this framework. * switch iomd and acorn32 to use this framework. * switch shark to use this framework. * port any other arm platforms that are interested * examine overlaps between this code and ppcoea-renovation branch. * add support for different trigger types (Edge, level, pulse, etc) (note that iomd and shark currently touch hardware on every spl change, hence why they're targets to port)

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.

1.15	10-May-2008	chris	branches: 1.15.6; 1.15.12; Fix 9.5 year old buffer overflow. It wasn't noticed till now as it wasn't overflowing onto anything important (or was overwritten by the correct data). Recent changes meant irqstr was placed just before footbridge_intrq and so it trashed the interrupt linked list, and so caused an alignment fault. Note that cats still doesn't boot even with the change, as it hangs when starting userland, I suspect an interrupt issue.
1.14	14-Dec-2007	chris	branches: 1.14.6; 1.14.8; 1.14.10; 1.14.12; Fix for PR cats/18026. cats was never able to dump a kernel core dump because reading from VGA addresses (0xb8000) was causing the system to hang. To workaround this reprogram the footbridge to map the memory to appear on the PCI bus at 0x20000000, rather than at 0x0. Also configure the pci bus to have a DMA range so that data is mapped correctly. Note that -current kernels seem to hang when unmounting the fs. This is a seperate issue, and appears to be because interrupts need to be enabled to unmount filesystems. So using reboot 0x104 does work, as it does a sync without unmounting the filesystems. Also arm savecore doesn't do anything with the memroy dump, as on arm we currently just dump the raw memory, there's no header block to indicate memory sizes or other useful information.
1.13	25-Feb-2007	chris	branches: 1.13.18; 1.13.22; 1.13.24; 1.13.32; 1.13.36; Make this file compile with PCI_DEBUG defined. Needed to figure out why the latest ABLE firmware was causing an interrupt mapping issue on cats. It seems that the latest ABLE firmware is using native-PCI mode, rather than compatibility mode, but doesn't setup an irq for us to use, so we fail to map the interrupt handler.

1.8	03-Nov-2002	chris	Checkin new interrupt handling code for the footbridge. This is based upon Jason's work on xscale. Most of the interrupt handling code is now written in C using an asm stub to call into the C code. spl* now only updates a software mask, and does not update the hardware, this should be much faster. The new code works well on cats, it's untested on netwinder, but should work. The code implements generic soft interrupts. More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future.

1.6	27-Sep-2002	provos	remove trailing \n in panic(). approved perry.
1.5	17-Aug-2002	thorpej	Use separate function pointers for dmamap_sync pre- vs post- operations. Change the bus_dmamap_sync() macro to test the ops argument against pre- and post- constants. The compiler will optimize out dead code because of the constants. Since post- operations are not needed on ARM (except for ISA bounce buffers), this eliminate a large number of function calls which are noops, each of which cost at least 6 cycles just in the call and return overhead (not to mention whatever other useless work the compiler decides to do in the callee).
1.4	05-Sep-2001	matt	branches: 1.4.6; 1.4.14; Change <machine/irqhandler.h> to <machine/intr.h> since the latter always includes the former and is a standard include file.

1.3	23-Mar-2003	chris	Add __KERNEL_RCSID tags to footbridge files.
1.2	03-Nov-2002	chris	Checkin new interrupt handling code for the footbridge. This is based upon Jason's work on xscale. Most of the interrupt handling code is now written in C using an asm stub to call into the C code. spl* now only updates a software mask, and does not update the hardware, this should be much faster. The new code works well on cats, it's untested on netwinder, but should work. The code implements generic soft interrupts. More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future.
1.1	12-Oct-2002	chris	branches: 1.1.2; 1.1.4; 1.1.6; Merge isa_machdep.c from netwinder and cats into footbridge/isa (where it joins other machdep files) Saves maintaining multiple copies of the same thing, the only differences were: IRQ line used on the footbridge (made that a define in include/isa_machdep.h) name of a dma_ranges variable contained arch name, so just made it generic.

1.6.50.2	18-Aug-2007	chris	Rework registration call, so that it no longer takes a status paramater. Rework dispatch routines, so no implicit ordering is required in the irq groups. This removes the primary flag, and also makes hardware dependant dispatch routines again. Update arm_intr_queue_irqs to disable interrupts. This is necessary when child buses are present, eg isa bus, as the isa interrupt handler is called with interrupts enabled, and I believe that the footbridge handler was trampling on the isa handler setting up pending flags. cats can now install using the update irq code (previously it would randomly hang)
1.6.50.1	12-Aug-2007	chris	Switch footbridge isa to use common code. This required changes to the arm code: * intr_claim now takes a type to indicate edge, level or pulse.

1.16	21-Sep-2012	matt	Switch to the generic bounce buffer support.
1.15	12-Feb-2012	matt	branches: 1.15.6; Change old-style function defintions to C89 prototypes. Approved by releng.
1.14	01-Jul-2011	dyoung	branches: 1.14.2; 1.14.6; #include <sys/bus.h> instead of <machine/bus.h>.
1.13	18-Mar-2009	cegger	Ansify function definitions w/o arguments. Generated with sed.
1.12	14-Mar-2009	dsl	ANSIfy another 1261 function definitions. The only ones left in sys are beyond by sed script! (or in sys/dist or sys/external) Mostly they have function pointer parameters.
1.11	14-Mar-2009	dsl	Remove all the __P() from sys (excluding sys/dist) Diff checked with grep and MK1 eyeball. i386 and amd64 GENERIC and sys still build.

1.4	23-Mar-2003	chris	Add __KERNEL_RCSID tags to footbridge files.
1.3	17-Aug-2002	thorpej	Use separate function pointers for dmamap_sync pre- vs post- operations. Change the bus_dmamap_sync() macro to test the ops argument against pre- and post- constants. The compiler will optimize out dead code because of the constants. Since post- operations are not needed on ARM (except for ISA bounce buffers), this eliminate a large number of function calls which are noops, each of which cost at least 6 cycles just in the call and return overhead (not to mention whatever other useless work the compiler decides to do in the callee).
1.2	31-Jul-2002	thorpej	Overhaul how DMA ranges work in the ARM bus_dma implementation. A new "arm32_dma_range" structure now describes a DMA window, with a system address base, bus address base, and length. In addition to providing info about which memory regions are legal for DMA, the new structure provides address translation support, as well. As before, if a tag does not list any ranges, then all addresses are considered valid, and no DMA address translation is performed. This allows us to remove a large chunk of code which was duplicated and tweaked slightly (to do the address translation) from the stock ARM bus_dma in the XScale IOP and ARM Integrator ports. Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.
1.1	10-Feb-2002	chris	branches: 1.1.2; 1.1.10; 1.1.14; Following the demise of arch/arm32 update cats, and restore the isa files to a more sane location. Also fix build break on GENERIC cats kernel, seems that conf.h should have been including arm/conf.h. This completes the removal of arch/arm32.

1.2	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
