The BIOS doesn't contain this setting? (I've yet to meet a laptop
without a BIOS setup.) I checked /proc here, and /proc/pci does change
when I modify the BIOS 'assign IRQ to VGA' setting by adding a IRQ
number to the end of the device line (like this example, from a laptop):
Bus 0, device 8, function 0:
VGA compatible controller: Neomagic Corporation [MagicMedia 256AV]
(rev 32).
IRQ 9.
When the BIOS setting is off, the only difference seems to be removal of
the 'IRQ 9' part.
However, /proc/interrupts is not an indicator. It shows no change.
Only devices which are tied to kernel drivers are listed here.
If you want to really cut back the virge driver, try the following; you
listed:
---
Section "Device"
Identifier "S3 ViRGE/MX"
VendorName "S3"
Driver "s3virge"
BoardName "ViRGE/MX"
Option "fifo_aggressive"
Option "pci_burst"
Option "pci_retry"
EndSection
---
Comment out the options:
Option "fifo_aggressive"
Option "pci_burst"
Option "pci_retry"
and add
Option "noaccel"
then try your test again. Also, verify again that an IRQ doesn't appear
in /proc/pci. If you do run this, I'd be interested in seeing the log
file again. Don't know if anyone else cares, so feel free to send it to
me privately.
