Summary: No hardware rendering for "SuperSavage/IXC 64" and "Xorg
7.2 RC3"
Kernel Version: 2.6.20-rc3-git3
Status: NEW
Severity: normal
Owner: [EMAIL PROTECTED]
Submitter: [EMAIL PROTECTED]
Most recent kernel where this bug did *NOT* occur: none
Distribution: "Fedora Core [Development]"
Hardware Environment: "IBM ThinkPad T23"
Software Environment: n/a
Problem Description: Obsolete kernel "DRM" modules in kernel "2.6.20-rc3-git3"
inhibit hardware rendering for "SuperSavage/IXC 64". For the new upstream
version 2.1.12 of the "savage" driver in "Xorg 7.2 RC3", "glxinfo" reports:
"libGL error: drmMap of framebuffer failed (Invalid argument)"
"libGL error: reverting to (slow) indirect rendering"
This error was absent for driver version 2.1.11.
Steps to reproduce:
1. Install "savage" driver version 2.1.12.
2. Restart "X".
3. Log in to "X" session and execute "glxinfo".
Additional comment: After compiling the latest "drm.ko" and "savage.ko" from
[http://anongit.freedesktop.org/git/mesa/drm] and loading them prior to starting
the "X" server, hardware rendering is back and working as before.
