thorpej | Reduce code duplication among platforms that use the i82378 SIO to
route PCI interrupts to the ISA PIC by refactoring it into a new
sio_pirq_intr_map() function.

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().

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.

Do a minor cleanup of alpha (this will make applying pullups post branching
easier).

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.
With these changes in place, I have tested the compilation of these

ANSIfy functions with function-pointer arguments
|

| 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.
|
| 1.34 |
| 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.)
|

Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

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.)

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

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.
|
| 1.15 |
| 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.
|
| 1.14 |
| 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.)

cgd | update for new bus.h macros. bus_io_* and bus_mem_* integrated into
single bus_space_* framework. Unfortunately, bus_space_{read,write}_*
operations still imply barriers. That will change soon.

-current, as well as machine-dependant code.
