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().

thorpej | branches: 1.16.6; 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.

christos | gc sprintf; reduce local static usage of interrupt strings that are only used once for autoconf printing.

| 1.14 |
| 01-Jul-2011 |
dyoung | branches: 1.14.2; 1.14.12; 1.14.16; #include <sys/bus.h> instead of <machine/bus.h>.
|
| 1.13 |
| 14-Jun-2011 |
matt | 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).
|
| 1.12 |
| 04-Apr-2011 |
dyoung | branches: 1.12.2; 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:

| 1.11 |
| 15-Dec-2010 |
matt | branches: 1.11.2; Remove unneeded includes of <uvm/uvm_extern.h>
|
| 1.10 |
| 28-Apr-2008 |
martin | branches: 1.10.22; Remove clause 3 and 4 from TNF licenses
|

| 04-Mar-2007 |
mrg | branches: 1.9.40; 1.9.42; 1.9.44; avoid unused variable warnings in pci_up1000_pickintr().
|
| 1.8 |
| 15-May-2002 |
thorpej | branches: 1.8.26; 1.8.64; 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
