Summary: i915 driver broken after ttm-cleanup-branch merge
Product: DRI
Version: DRI CVS
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: critical
Priority: medium
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
I am tring to use the mesa drm i915 driver from git master
current commit 7e6d08f670a55d79ee037144aa29104e4e8fc700
with Mesa 7.0 i915tex_dri.so and xserver 1.3 and the git master
current xf86-video-intel driver compiled with the git version of
libdrm from the same above commit.
I run the xserver with xterm as the only client and run glxinfo
# glxinfo
name of display: :0.0
libGL warning: 3D driver claims to not support visual 0x73
Failed to initialize batch pool - possible incorrect agpgart installed
Segmentation fault
I get the following in dmesg:
Linux agpgart interface v0.102 (c) Dave Jones
agpgart: Detected an Intel 915GM Chipset.
agpgart: Detected 7932K stolen memory.
agpgart: AGP aperture is 256M @ 0xc0000000
[drm] Initialized drm 1.1.0 20060810
ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 169
PCI: Setting latency timer of device 0000:00:02.0 to 64
[drm] Initialized i915 1.9.0 20070209 on minor 0
[drm:drm_lookup_buffer_object] *ERROR* Could not find buffer object 0x6c635f54
Using the setup described above works perfectly with git drm driver
