xorg/driver/xf86-video-vga - [PATCH] Add libpciaccess support to generic vga driver.

[pcpa at mandriva.com.br]

Quoting pcpa at mandriva.com.br:

  I am a bit unsure if the proper implementation of
generic.c:GenericPciProbe() would be more like:

--
vgaHWPtr vgahw = VGAHWPTR(pScrn);
...
vgahw->dev = dev;
--

instead of the patch I posted where I added the field
struct pci_device *pciInfo;
to GenericRec, and used code like:

--
GenericPtr pGeneric = GenericGetRec(pScrn);
...
pGeneric->pciInfo    = dev;
--

but generic.c doesn't use the pci_device information, while
xorg/xserver/hw/xfree86/vgahw/vgaHW.c
intializes the field in function vgaHWGetHWRec() in code like:
hwp->dev = xf86GetPciInfoForEntity(scrp->entityList[0]);

and uses it in function vgaHWMapMem():
hwp->Base = xf86MapDomainMemory(scr_index, VIDMEM_MMIO_32BIT, hwp->dev,
				    hwp->MapPhys, hwp->MapSize);

In either case, the vga driver doesn't work in my computer, but
an older version doesn't lock the computer, just doesn't show anything
resembling a desktop...
