My setup: * kernel 3.2 * libdrm 2.4.30 * mesa 7.11.2 I replaced the bios with a modded one that allow tweaking of video ram type. I tried two settings: uma only and uma+sideport. * UMA (256M) * No graphic corruption * No laggy window movement * glxgear fps ~= 360 * UMA+sideport (256M+64M) * Massive graphic corruption * Laggy window movement * glxgears fps ~= 200 A diff between dmesg output: $ diff dmesg.uma dmesg.uma+sideport 9c9 < [drm] Detected VRAM RAM=256M, BAR=256M --- > [drm] Detected VRAM RAM=384M, BAR=256M 11c11 < [drm] radeon: 256M of VRAM memory ready --- > [drm] radeon: 384M of VRAM memory ready 15c15 < [drm] PCIE GART of 512M enabled (table at 0x000000006C180000). --- > [drm] PCIE GART of 512M enabled (table at 0x000000006B800000). 31a32 > [drm] radeon: power management initialized Hope it can help.
