[PATCH] agp/amd-k7: Allow binding user memory to the AGP GART.
by Francisco Jerez 16 Oct '10

16 Oct '10

TTM-based DRM drivers need to be able to bind user memory to the AGP aperture. This patch fixes the "[TTM] AGP Bind memory failed." errors and the subsequent fallout seen with the nouveau driver.

Regression: DVI monitor "not connected" after drm starts at bootup on kernel 2.6.35-7
by Jasper Klein 16 Oct '10

16 Oct '10

Hello dri-devels, I'm running a Slackware64-current setup and updated it to use the 2.6.35 kernel. On the next reboot my monitor went dark and into "power-saving mode" when drm started at boot. The screen remains on until that moment, so i still have vision of all the debug output the kernel throws at bootup before drm starts. The same setup worked on slackware64-current with the 2.6.33 kernel. Hardware used: A monitor connected to DVI. Physical setup didn't change. Monitor information from Xorg.0.log: (II) intel(0): EDID vendor "GSM", prod id 22136 (II) intel(0): Using EDID range info for horizontal sync (II) intel(0): Using EDID range info for vertical refresh (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline "1680x1050"x0.0 119.00 1680 1728 1760 1840 1050 1053 1059 1080 +hsync -vsync (64.7 kHz) ... some more modelines ...

Tested setups that were broken: - Distro: Slackware64-current - Xorg 1.7 - Kernel 2.6.35-7 (from distro) - Distro: Slackware64-current - Xorg 1.7 - Kernel 2.6.36-rc8 (custom compile) - Distro: Ubuntu Linux (x64) - Xorg 1.9 - Kernel 2.6.35-7 (from distro) In all the broken setups the dvi-connected display switches off just after drm is loaded at bootup. VGA works fine. xrandr -q tells me the dvi display is not connected. Thanks in advance,

It should, since it simply puts vram at 0 when it is detected that gtt and vram are adjacent. dmesg says: ---8<--------- radeon 0000:01:00.0: GTT: 256M 0xD0000000 - 0xDFFFFFFF radeon 0000:01:00.0: VRAM: 64M 0x00000000 - 0x03FFFFFF (64M used) --->8--------- so it has moved vram to 0. I'll test it just the same though :) One thing I am wondering is if it is possible to get vram/gtt overlapping with this, since this patch doesn't seem to perform any further checks to ensure this when moving either vram or gtt to 0? Presumable this already handled elsewhere? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
