https://bugzilla.kernel.org/show_bug.cgi?id=42920 --- Comment #7 from j.fikar@xxxxxxxxx 2012-03-15 14:26:25 --- ok, so vramlimit works, but doesn't solve my problem. I have tried 128MB UMA with vramlimit=64 and then 256MB UMA with vramlimit=64. The memory gets smaller, but is wrongly located? 128MB: [ 7.005921] radeon 0000:01:05.0: VRAM: 128M 0x00000000C0000000 - 0x00000000C7FFFFFF (64M used) [ 7.005923] radeon 0000:01:05.0: GTT: 512M 0x00000000A0000000 - 0x00000000BFFFFFFF [ 7.082407] [drm] PCIE GART of 512M enabled (table at 0x00000000C0040000). 256MB: [ 6.097567] radeon 0000:01:05.0: limiting VRAM [ 6.097569] radeon 0000:01:05.0: VRAM: 3584M 0x000000FFFF000000 - 0x00000100DEFFFFFF (64M used) [ 6.097571] radeon 0000:01:05.0: GTT: 512M 0x00000100DF000000 - 0x00000100FEFFFFFF [ 6.663271] [drm] PCIE GART of 512M enabled (table at 0x000000FFFF040000).
