thorpej | Remove unnecessary #include <sys/malloc.h>
|
1.49 |
| 04-Jul-2021 |
thorpej | Reduce code duplication when setting up the interrupt handler data structures: - alpha_shared_intr_alloc() no longer takes a "string length" argument, and just uses kmem_asprintf() to create an "irq %u" string by default. This is suitable for nearly every caller. - Add a alpha_shared_intr_set_string() that allows callers to override the default IRQ description string. - Related: make alpha_shared_intr_string() return a const char *, since no callers should need to modify the string directly now. - Re-factor PCI shared interrupt structure allocation / initialization into a new alpha_pci_intr_alloc(), which is suitable for nearly every Alpha PCI platform. Callers are expected to first have initialized the interrupt hardware to the quiescent state.
Adjust various call sites of above functions to account for changes, even if they are not able to use the newly re-factored code.
|
1.48 |
| 25-Jun-2021 |
thorpej | Tweak how the IRQ description strings are generated to enable additional duplicated code re-factoring.
|
1.47 |
| 19-Jun-2021 |
thorpej | Don't use a bunch of switch() statements in the core logic drivers to select the PCI interrupt initialization routine. Instead, register said routines by systype in a link set, and look them up and invoke them in a new function alpha_pci_intr_init().
|
1.46 |
| 22-Sep-2020 |
thorpej | branches: 1.46.6; Changes to make MPSAFE interrupts work on Alpha:
- Remove the ipl argument to scb_set() and the associated array of "mpsafe" booleans initialized based on the ipl. It was bogus anyway; all IPL_{BIO,NET,TTY}, etc. values are aliases of IPL_VM, and for all practical purposes, there is really only one device interrrupt level on Alpha anyway. Intead, we now treat all dispatches from the SCB vector table as MP-safe, and it is now the handler for that vector who is responsible for acquiring the KERNEL_LOCK if needed.
- Update the direct interrupt vector handlers in jensenio and TURBOchannel to acquire the KERNEL_LOCK.
- Introduce a new ALPHA_INTR_MPSAFE flag, and add a flags argument to alpha_shared_intr_establish(). When it is set, indicate that the handler is MP-safe. Update alpha_shared_intr_dispatch() to pay attention and acquire the KERNEL_LOCK (or not) as indicated.
- Re-factor all of the PCI interrupt handling, providing "generic PCI" "PCI interrupts through ISA IRQs" implementations to significantly reduce code duplication. Supplement the PCI chipset tag with more info to facilitate this, and make the PCI interrupt-related routines take a pci_chipset_tag_t argument rather than a void * argument.
- Because PCI interrupts on KN8AE are dispatched directly from the SCB, provide a wrapper for non-MPSAFE interrupt handlers that acquires the KERNEL_LOCK.
- Change the pci_intr_handle_t type to be a struct rather than an integer type in order to catch any direct use of it as a value. Add a set of functions to interact with pci_intr_handle_t, including setting interrupt flags.
- Implement pci_intr_setattr() so that the PCI_INTR_MPSAFE attribute can be set on a pci_intr_handle_t.
- While I'm here, make all of the MI PCI back-end operations call through real functions rather than hopping directly through function pointers in the chipset tag.
This change looks a lot bigger than it really is because of the re-factor in the plethora of model-specific PCI interrupt back-ends. The KN8AE, KN300, and T2/T3/T4 (Sable) are largely un-changed.
|
1.45 |
| 21-Mar-2014 |
christos | gc sprintf; reduce local static usage of interrupt strings that are only used once for autoconf printing.
|
1.44 |
| 06-Feb-2012 |
matt | branches: 1.44.6; 1.44.10; Do a minor cleanup of alpha (this will make applying pullups post branching easier). u_int{8,16,32,64}_t -> uint{*}_t Change all old-style definitions to C89 prototypes. Whitespace cleanup. Constification in db_disasm.c
|
1.43 |
| 14-Jun-2011 |
matt | branches: 1.43.2; 1.43.6; Major cleanup of alpha device drivers. Switch to CFATTACH_DECL_NEW. struct device * -> device_t struct cfdata * -> cfdata_t Use of device_xname. No direct access to struct device members. Use aprint* (not complete).
|
1.42 |
| 04-Apr-2011 |
dyoung | branches: 1.42.2; 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.
With these changes in place, I have tested the compilation of these kernels:

1.41 |
| 15-Dec-2010 |
matt | branches: 1.41.2; Remove unneeded includes of <uvm/uvm_extern.h>
|
1.40 |
| 16-Mar-2009 |
dsl | branches: 1.40.4; ANSIfy functions with function-pointer arguments
|
1.39 |
| 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.
|
1.38 |
| 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.)
|
1.37 |
| 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.
|
1.36 |
| 28-Apr-2008 |
martin | branches: 1.36.8; 1.36.14; Remove clause 3 and 4 from TNF licenses
|
1.35 |
| 03-Dec-2007 |
ad | branches: 1.35.14; 1.35.16; 1.35.18; 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.
|
1.34 |
| 11-Dec-2005 |
christos | branches: 1.34.30; 1.34.48; 1.34.50; 1.34.56; merge ktrace-lwp.
|
1.33 |
| 29-Mar-2005 |
thorpej | branches: 1.33.2; - Add a alpha_shared_intr_reset_strays() function that resets the stray interrupt counter for a given shared interrupt descriptor. - When an interrupt is successfully handled, reset the strays counter, thus preventing a "slow leak" from eventually shutting off the interrupt vector. Idea taken from pci_kn300.c (which was changed to use the new alpha_shared_intr_reset_strays() function).
|
1.32 |
| 27-Sep-2002 |
provos | branches: 1.32.6; 1.32.12; 1.32.14; 1.32.20; remove trailing \n in panic(). approved perry.
|
1.31 |
| 15-May-2002 |
thorpej | Rename alpha_pci_decompose_tag() to pci_decompose_tag(). There *is* some MI PCI code that uses it, and soon there will be more. (The rationale for not making it available previously was that it could be mis-used, but that's true of a lot of things.)
|
1.30 |
| 27-Jul-2001 |
thorpej | branches: 1.30.2; Rework the interrupt code, shaving some cycles off in the process. Rather than an "iointr" routine that decomposes a vector into an IRQ, we maintain a vector table directly, hooking up each "iointr" routine at the correct vector. This also allows us to hook device interrupts up to specific vectors (c.f. Jensen).
We can shave even more cycles off, here, and I will, but it requires some changes to the alpha_shared_intr stuff.
|
1.29 |
| 28-Dec-2000 |
sommerfeld | branches: 1.29.4; Change pci_intr_map to get interrupt source information from a "struct pci_attach_args *" instead of from four separate parameters which in all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI interrupt mapping schemes, such as one using the tables described in the Intel Multiprocessor Spec which describe interrupt wirings for devices behind pci-pci bridges based on the device's location rather the bridge's location.
Tested on alpha and i386; welcome to 1.5Q
|
1.28 |
| 29-Jun-2000 |
mrg | remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
|
1.27 |
| 06-Jun-2000 |
thorpej | Report which compatibility IRQ the PCI IDE gets.
|
1.26 |
| 05-Jun-2000 |
thorpej | Switch to the new `evcnt' mechanism for counting interrupts. Maintain a per-CPU interrupt counter for clock, device, and interprocessor interrupts.
|
1.25 |
| 04-Jun-2000 |
cgd | Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
|
1.24 |
| 12-Feb-1999 |
thorpej | branches: 1.24.8; 1.24.16; Fix printf format problems on Alpha.
|
1.23 |
| 01-Aug-1998 |
thorpej | Implement pci_intr_disestablish().
|
1.22 |
| 07-Jul-1998 |
thorpej | On second thought, call that like the rest of the shared intr functions.
|
1.21 |
| 07-Jul-1998 |
thorpej | Fix typi.
|
1.20 |
| 07-Jul-1998 |
thorpej | The Pyxis core logic in the 164SX and 164LX seems to have problems with stray interrupts. Do what Digital UNIX (formerly DEC OSF/1) does; just ignore strays.
|
1.19 |
| 07-Jul-1998 |
thorpej | Use ALPHA_SHARED_INTR_DISABLE() to test if a shared interrupt should be disabled after a stray.
|
1.18 |
| 05-Jun-1998 |
thorpej | Don't attempt to map the PCI IDE interrupt at bus 0 device 11 on the AlphaPC 164 and AlphaPC 164LX - these are wired to compatibility mode.
|
1.17 |
| 24-May-1998 |
matt | Only disable stray interrupts if there is no interrupt handler attached
|
1.16 |
| 11-May-1998 |
thorpej | Rework PCI interrupt mapping on the EB164 systype. Rather than computing interrupt routing directly, use the interrupt routing information provided in the PCI "line" register. The previous scheme did not work properly on AlphaPC 164SXs. Also, be silent about the fact that 0/8/x does not have its interrupt mapped; this is to be expected on the 164SX (this is the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions 1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).
|
1.15 |
| 25-Apr-1998 |
thorpej | Fix some whitespace lossage.
|
1.14 |
| 18-Apr-1998 |
thorpej | First cut at PCI IDE compat interrupt support for the EB164 systype. PCI IDE is found on the AlphaPC 164SX's Cypress PCI-ISA bridge.
|
1.13 |
| 16-Apr-1998 |
thorpej | Make function names in printfs and panics consistent.
|
1.12 |
| 16-Apr-1998 |
thorpej | Allow device 8 (the SIO) to have its interrupt mapped; there might be a PCI IDE controller on one of the PCI-ISA bridge's functions (e.g. AlphaPC 164SX).
|
1.11 |
| 14-Apr-1998 |
thorpej | Pass the pci_chipset_tag_t to sio_intr_setup(). XXX This code should be rearranged so that other non-PCI-but-in-all-other-ways-ISA-PIC-like devices can share code.
|
1.10 |
| 02-Sep-1997 |
thorpej | Adjust for changes to bus space tag initialization.
|
1.9 |
| 02-Sep-1997 |
thorpej | Nuke the idea of <machine/options.h>. It completely defeats the purpose of fine-grain option dependencies.
|
1.8 |
| 19-Jul-1997 |
cgd | branches: 1.8.2; don't expect/provide pci_decompose_tag to be a MI, public function. It wasn't intended to be to begin with, and uses of it (e.g. the one in the 'de' driver) are quite likely to be incorrect.
|
1.7 |
| 31-May-1997 |
cgd | Adjust gcc -Wuninitialized warning initializers (or add them) so that compliation without DEBUG and/or DIAGNOSTIC happens without errors. Note that all such initializations in the Alpha port are marked with "XXX gcc -Wuninitialized". As far as I'm concerned, the one or two times -Wuninitialized has saved me from problems are worth the (very minor) cost involved with the initializations, esp. if it's noted why the initializations are done. This was prompted by PR#3690, from Ted Lemon.
|
1.6 |
| 07-Apr-1997 |
cgd | by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries. This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS options, which is present but commented out in the ALPHA config file. In ELF-format kernels, these strings are present in the kernel binary but are not loaded into memory. (In ECOFF-format kernels, there's no easy way to keep them from being loaded, so they _are_ loaded into memory.)
|
1.5 |
| 07-Apr-1997 |
cgd | clean up NetBSD RCS ID strings, include machine/options.h
|
1.4 |
| 25-Nov-1996 |
cgd | branches: 1.4.2; make eb164 interrupts actually work.
|
1.3 |
| 17-Nov-1996 |
cgd | implement interrupt enable/disable and mapping as described in the Digital Semiconductor AlphaPC 164 Motherboard Technical Reference Manual. This may not work, but it's the best i can do with the documentation I have.
|
1.2 |
| 13-Nov-1996 |
cgd | compile cleanly with: -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual
|
1.1 |
| 11-Nov-1996 |
cgd | preliminary support for the EB164. The EB164 is more or less a 'normal' 21164 + 21172 box, with Yet Another Way of doing interrupts. The interrupt mapping and handling code hasn't been written yet, and none of this code has been tested. (Checkpoint of work in progress.)
