Summary: DRI stops to work after libpciaccess enable xorg-server
upgrade
Product: DRI
Version: XOrg CVS
Platform: PowerPC
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: General
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
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)
