Subject: Oops when reading /proc/dri/0/vm with r128 on Inspiron 4000
Date: Sun, 9 Sep 2001 14:39:32 +0200 [thread overview]
Message-ID: <20010909143932.A500@ilm.nlc.no> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 5016 bytes --]
Hi,
DRI won't work on my Dell Inspiron 4000 with an ATI Rage Mobility M3 graphics
chip. I've tried both 2.4.9 and -ac6, both the stock DRM and from CVS today.
The kernel seems to find the card just fine, according to dmesg, but
/dev/dri/0/ is not created (I'm running devfs).
The dmesg output for the card is:
[drm] AGP 0.99 on Intel 440BX @ 0xf0000000 64MB
[drm] Initialized r128 2.1.6 20010405 on minor 0
X on the other hand, says:
(II) R128(0): Direct rendering disabled
When cat'ing /proc/dri/0/vm I get a NULL pointer dereference oops, after which all
reading from any file (except name) in /proc/dri/0/ hangs in uninterruptible
sleep until I reboot. On 2.4.9-ac6 with drm from cvs (no agpgart loaded), the
decoded oops is as follows (I ran ksymoops immediately after the oops, so the
warnings can be ignored):
ksymoops 2.4.2 on i686 2.4.9-ac6. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.9-ac6/ (default)
-m /boot/System.map-2.4.9-ac6 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Warning (compare_maps): mismatch on symbol zeroes , ipsec says d09144c0, /lib/modules/2.4.9-ac6/kernel/net/ipsec/ipsec.o says d09143c0. Ignoring /lib/modules/2.4.9-ac6/kernel/net/ipsec/ipsec.o entry
