Re patch 4.6.99.17-4.6.99.18.diff.bz2 breaks i810 driver on Dell machines

Okay, more investigation on this error.

I noticed the same message (****INVALID IO ALLOCATION****) in the logfile
for another chipset (ATI Technologies Inc RS480 [Radeon Xpress 200G 
Series])
on a Nec VL350 computer. I noticed a beep when starting XFree86, which 
this
time doesn't fail. This beep probably comes from the BIOS. I tested again
on the Dell GX270 and Dell GX280 and, indeed, they emit the beep too (but, 
as said,
XFree86 fails on the computers).

I looked deeper into the patch 4.6.99.17-4.6.99.18.diff.bz2 and found that 
this
file modified by the patch is the culprit :

xc/programs/Xserver/hw/xfree86/os-support/bus/linuxPci.c (1.14)

bugfixes :

111. Various PCI-related changes (Marc La France):
     [...]

So it has to be reworked, I think.

patch 4.6.99.17-4.6.99.18.diff.bz2 breaks i810 driver on Dell machines







Hello, 

I'm building XFree86 4.6+patches for a selection of computers with various 
video chipsets. 
The kernel is a 2.4.34. 

I found that the patch 4.6.99.17-4.6.99.18.diff.bz2 breaks the i810 driver 
for the Intel 
graphic chipset on these two Dell computers : 

- Dell Optiplex GX270 / i865G 
- Dell Optiplex GX280 / i915G 

But note that this computer works well : Dell Optiplex GX260 / i845G 

The syndrome : as soon as X startx, the screen becomes dark and the text 
consoles become unusable too 
(but the system doesn't crash). I can see this in /var/log/XFree86.0.log 
(this example is for the i915G) : 

[...] 
(--) Chipset 915G found 
(II) resource ranges after xf86ClaimFixedResources() call: 
[...] 
(II) Found conflict at: 0x3df 
(II) Found conflict at: 0x3bb 
(WW) ****INVALID IO ALLOCATION**** b: 0xe898 e: 0xe89f correcting^G 
(II) window: 
        [0] -1  0       0x00000000 - 0x0000ffff (0x10000) IX[B] 
(II) resSize: 
        [0] -1  0       0x00000000 - 0xffffffff (0x0) IX[B] 
(II) window fixed: 
        [0] -1  0       0x00000000 - 0x0000ffff (0x10000) IX[B] 

and the log file stops here. 

Moreover, I have the same graphic chipsets (i865G and i915G) on non-Dell 
motherboards 
(MSI or Intel motherboards) and they work perfectly here. So I suspect 
that the problem comes from 
the Dell BIOS. Dell BIOSes are mostly not configurable, as you may know, 
and I didn't find a parameter 
which could be related to the problem. 

There are some pci-related files which are altered by the patch, the error 
probably comes from there.
