Spiritual revert of 1fa4de80fc. Intel's C
compiler claims to be gcc-compatible; if they're not defining the same
macros as gcc then that's their bug, not ours. Even if we were to do
this aliasing we should do it once and for all in servermd.h.
xserver and libpciaccess both need to open /dev/xf86, which can only
be opened once. I implemented pci_system_init_dev_mem() like Ian
suggested. This requires some minor changes to the BSD-specific
os-support code. Since pci_system_init_dev_mem() is a no-op on
FreeBSD this should be no problem.
FindPCIVideoInfo() function isn't need anymore.
xf86scanpci() is being called only once so we don't need permanent
(static) variables there.
restorePciState() is not used for now (until we find why multiple
cards aren't working).

Fixes compiler errors:
"ix86Pci.c", line 194: too many struct/union initializers
"ix86Pci.c", line 204: too many struct/union initializers
"ix86Pci.c", line 214: too many struct/union initializers
Note that pciaccess doesn't yet have Net/OpenBSD support, but the relevant
code should go there instead of disconnected code in the X Server.
While here, remove the now-disabled INCLUDE_XF86_NO_DOMAIN from the headers,
and un-disable xf8StdAccResFromOS for those OSes without domain support which
will need it.
This was a bunch of poorly defined resource ranges per OS/platform combination
which were supposed to represent what regions could potentially have resources
allocated into them.
The code in hw/xfree86/os-support/bus/sparcPci.c:simbaCheckBus()
is trying to mimmick VGA routing by disabling I/O space responses
behind the Simba PCI-PCI controller.
Unfortunately, doing this also happens to disable access to the
IDE controller I/O space registers, thus crashing the system. The
granularity of the I/O disabling in the Simba controller is not
fine enough to disable VGA without also disabling the IDE controller
registers.
Formerly we sized an array with a compile time constant, then initialized
its size to the same constant, but the Linux PCI init code would increase
that "constant". So if you happened to have more than 128 PCI devices,
you'd happily scribble into whatever variables happened to be in .bss
after that array.
Only really fixed for Linux atm. Other OSes will simply (still) fail to
work on video devices above the 128th PCI device.
/sys/devices reflects the bus topology, and we don't care that much.
Easier (and more reliable) to just look in /sys/bus/pci/devices, which
is a flat view.
Currently, the call to linuxPciOpenFile() is always made for read
only access which causes the subsequent mmap call to fail when the
memory is mapped read/write.
Xorg #9692
xf86ReadLegacyBIOS is only used by one function in int10/generic.c.
Move a generic implementation of that function there, rename it to
read_legcay_BIOS, and delete all remnants of it from all other places.
Convert xf86GetPciHostConfigFromTag to a new function called
get_parent_bridge. This name better represents what
xf86GetPciHostConfigFromTag is used for: walking up the lists of PCI
bridges from a device.
Eliminate xf86GetPciDomain. The domain from libpciaccess is the
domain. Period. This means that 0 is a valid domain. Make sure that
INCLUDE_XF86_NO_DOMAIN is *not* set. Always run in "domain mode,"
even if the only domain possible is 0.
Convert all uses of PCITAG in int10 and vgaHW to 'struct pci_device'.
This allows the conversion of xf86ReadLegacyVideoBIOS and
xf86MapDomainMemory to 'struct pci_device' from PCITAG.
