cherry | We reorganise definitions for XEN source support as follows:
XEN - common sources required for baseline XEN support.
XENPV - sources required for support of XEN in PV mode.
XENPVHVM - sources required for support for XEN in HVM mode.
XENPVH - sources required for support for XEN in PVH mode.

cherry | make
options NO_PCI_MSI_MSIX
work again for arch/x86/
|
| 1.47 |
| 27-Nov-2018 |
jdolecek | actually allow pci_intr_alloc() with NULL count with MSI-X
|
| 1.46 |
| 27-Nov-2018 |
jdolecek | make pci_intr_alloc() try also MSI-X by default (with NULL count);
there are boards/emulators which only have MSI-X and no MSI, and
so far there is no evidence there are devices which support both
and don't work in MSI-X mode
this change is supposed to reduce amount of needed cut&paste code in drivers
discussed briefly with jmcneill@

cherry | Revert:
http://mail-index.netbsd.org/source-changes/2018/09/10/msg098995.html
It is incorrect to infer semantics from usage.
the problem for which the original commit was intended should be fixed
within the callee intr_establish_xname() and not the caller:
pci_intr_find_intx_irq()
This was accomplished via:
http://mail-index.netbsd.org/source-changes/2018/09/20/msg099286.html

cherry | In the NIOAPIC case, we do not need to support "legacy" irqs,
ie; We don't need to simultaneously pass back the irq in the
range 0 < irq < 16 (which are sometimes described as "legacy"
in src
This was non-obvious, until the semantics of "legacy" were
used in inconsistent ways in Xen (to also mean interrupts in
the 0 < irq < 256 range) which causes problems with attempting
to unify the sys/arch/x86/isa/isa_machdep.c:isa_intr_establish_xname()
function between XEN and !XEN
This commit should not affect current functionality on any
either native or Xen. It is needed for future code reorg, and
published now as a preview.

jdolecek | branches: 1.43.2;
provide pci_intr_establish_xname() on x86 independantly from MSI,

symbol instead #ifdef

remove checks for failure after memory allocation calls that cannot fail:
kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

Use a loop instead of tail-recursion for the pci_intr(9) overrides.
This is the same change that I just made to the pci(9) overrides. While
I am here, fix a bug: use PCI_OVERRIDE_INTR_DISESTABLISH instead of
PCI_OVERRIDE_INTR_ESTABLISH for the pci_intr_disestablish(9) override.
|
| 1.22 |
| 17-Aug-2011 |
dyoung | In pci_msi_establish(), replace several anonymous constants with IOAPIC_
symbols. No change in the generated assembly.
|
| 1.21 |
| 17-Aug-2011 |
dyoung | Redefine PCI_MSI_* and PCI_PCIE_* constants in terms of bits(3).
Use named constants and more conventional variable names in
pci_msi_establish() and pci_msi_disestablish(). Fix a couple of bugs:
pci_msi_establish() returned a pointer to the struct intrhand instead of
to the struct msi_hdl as it was intended to, and pci_msi_disestablish()
did not free(9) the msi_hdl.
|
| 1.20 |
| 01-Aug-2011 |
drochner | add an experimental implementation of PCI MSIs (Message Signaled
Interrupts). Successfully tested with hdaudio and "wpi" wireless
ethernet.
notes:
-There seem to be buggy chips around which announce MSI support
but don't correctly implement it. Thus the final word whether MSIs
can be used should be by the driver.
-Only a single vector is supported. For multiple vectors, the IDT
allocation code would have to be changed. (And we would possibly
run into problems due to the limited number of vectors supported
by the current code.)
-The code is "#if NIOAPIC > 0" because it uses the ioapic_edge
interrupt stubs. These actually don't touch any ioapic, so this
is somewhat a misnomer.
-MSIs can't be identified by a "pin" but only by a cpu/vector
pair. Common intr code soesn't deal well with this yet.
-Drivers need to take care of saving/restoring MSI data in the device's
config space on suspend/resume.

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.
