over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
A bunch of CFLAGS had gone missing, so the build failed with errors like:
../../../../../hw/xfree86/os-support/linux/lnx_ev56.c:7:19: error: input.h: No such file or directory
../../../../../hw/xfree86/os-support/linux/lnx_ev56.c:8:24: error: scrnintstr.h: No such file or directory
The outport is most likely unnecessary on any currently used hardware,
the byte copy is necessary from what I know on IA64 and friends so leave it.
Add a new API entry point which lets a driver select the old behaviour if
such a needs is ever found.
This gives me ~20% speed up on startup on 945 hardware.
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.
