Bug #: 52950
Summary: [r200] piglit glean/blendFunc test fails
Classification: Unclassified
Product: Mesa
Version: 8.0
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/r200
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: mister.free...@laposte.net
System configuration :
- radeon 9000 AGP ( M9, rv250 )
- laptop pentium 4 2.4 Ghz 1.25 Gb ram
- archlinux 32 bits
Step to reproduce the bug
- mesa 8.0.4 release ( but the bug occurs also with the git version )
- a graphic card who uses the r200 driver
- install piglit ( git version )
- run the glean test "blendFunc" in piglit :
./piglit-run.py -t "glean/blendFunc" tests/quick.tests results/quick
the glean/blendFunc will fail with these error messages :
