Description Marcin Kurek 2008-04-08 08:42:21 UTC 
As I wanted to test is libpciaccess fixed bug #7248 I upgraded my xorg-server to recent git snapshot. The bug was fixed, but it seems that DRI stops to work here at all (mesa was upgraded to git too of coz).

I tired with both XAA and EXA using drm modules from 2.6.24 and from git with same results. Starting any GL app cause server crash (glxinfo command produce this crash too)

Looking in the logs I see:

(II) RADEON(0): [drm] failure adding irq handler, there is a device already using that irq
[drm] falling back to irq-free operation

I remember there was a similar problem before (I mean the symptoms of coz)

Also I wonder why card0 is opened so many times ?

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device or address)
drmOpenDevice: open result is -1, (No such device or address)
drmOpenDevice: Open failed
drmOpenByBusid: Searching for BusID pci:0001:01:08.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
drmOpenByBusid: drmOpenMinor returns 7
drmOpenByBusid: drmGetBusid reports pci:0000:01:08.0

It seems it opens card0 twice and the second one is successfull, but later:

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
drmOpenByBusid: Searching for BusID pci:0001:01:08.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 7, (OK)
drmOpenByBusid: drmOpenMinor returns 7
drmOpenByBusid: drmGetBusid reports pci:0000:01:08.0

And later:

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 8, (OK)
drmOpenByBusid: Searching for BusID pci:0001:01:08.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 8, (OK)
drmOpenByBusid: drmOpenMinor returns 8
drmOpenByBusid: drmGetBusid reports pci:0000:01:08.0
...
(EE) AIGLX error: drmOpenOnce failed (Operation not permitted)

Also I forgot to mention that my machine is Pegasos 2 1GHz G4 with 1GB of ram running kernel 2.6.24.

Not sure is this important in this case.
