| 1.20 |  | 25-Jun-2021 | thorpej | Remove pointless warning. 
 | 
| 1.19 |  | 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().
 
 | 
| 1.18 |  | 22-Sep-2020 | thorpej | branches:  1.18.6; 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.
 
 | 
| 1.17 |  | 21-Mar-2014 | christos | gc sprintf; reduce local static usage of interrupt strings that are only used once for autoconf printing.
 
 | 
| 1.16 |  | 06-Feb-2012 | matt | branches:  1.16.6;  1.16.10; 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

| 1.15 |  | 04-Apr-2011 | dyoung | branches:  1.15.4;  1.15.8; 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

 | 
| 1.14 |  | 15-Dec-2010 | matt | branches:  1.14.2; Remove unneeded includes of <uvm/uvm_extern.h>
 
 | 
| 1.13 |  | 16-Mar-2009 | dsl | branches:  1.13.4; ANSIfy functions with function-pointer arguments
 
 | 
| 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 | 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.)
 
 | 
| 1.10 |  | 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.
 
 | 
| 1.9 |  | 28-Apr-2008 | martin | branches:  1.9.8;  1.9.14; Remove clause 3 and 4 from TNF licenses
 
 | 
| 1.8 |  | 15-May-2002 | thorpej | branches:  1.8.112;  1.8.114;  1.8.116; 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.)
 
 | 
| 1.7 |  | 27-Jul-2001 | thorpej | branches:  1.7.2; 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.
 
 | 
| 1.6 |  | 28-Dec-2000 | sommerfeld | branches:  1.6.4; 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
 
 | 
| 1.5 |  | 29-Jun-2000 | mrg | remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h> 
 | 
| 1.4 |  | 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.
 
 | 
| 1.3 |  | 04-Jun-2000 | cgd | Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
 
 | 
| 1.2 |  | 19-Nov-1998 | ross | branches:  1.2.10;  1.2.18; #include <machine/intrcnt.h>
 
 | 
| 1.1 |  | 26-Jun-1998 | thorpej | Very preliminary support for the Tadpole/DEC AlphaBook.  These are basically AXPpci33 machines + power management and a Cirrus PCI-PCMCIA controller.
 
 There is currently no support for the power management facilities, and
 the PCI-PCMCIA controller driver needs some work, but this should boot
 and run from disk.

 (will be updated later). i386 IDE/ATAPI and ncr work, as well as
 sparc/esp_sbus. alpha should work as well (untested yet).
 siop, ahc and bha will be updated once I've updated the branch to current
 -current, as well as machine-dependant code.
