commit 4ca3550fb7d488741f8dc1ba3c8722393277c3b8 Author: Eric Anholt <e...@anholt.net> Date: Thu Oct 4 17:02:15 2007 -0700
This commit to the Intel driver tries to remove the sarea frontbuffer when you vt switch and add it back with a different size. While this may be a worthy goal, drm_rmmap won't allow a map to be removed that isn't SHM. These are AGP maps and neither linux or FreeBSD will allow the removal. So you end up with two maps at the same offset with different sizes. See maps 3 and 8. hw.dri.0.vm: slot offset size type flags address mtrr 0 0x00000000dff00000 0x00080000 REG 0x88 0x00000000ccffd000 no 1 0x00000000c4ac4000 0x00002000 SHM 0x20 0x00000000c4ac4000 no 2 0x00000000c0000000 0x00020000 AGP 0x00 0x0000000000000000 yes 3 0x00000000c1000000 0x00834000 AGP 0x00 0x0000000000000000 yes 4 0x00000000c4000000 0x00840000 AGP 0x00 0x0000000000000000 yes 5 0x00000000c5000000 0x00840000 AGP 0x00 0x0000000000000000 yes 6 0x00000000c6000000 0x02000000 AGP 0x00 0x0000000000000000 yes 7 0x00000000c0734000 0x00010000 AGP 0x00 0x0000000000000000 yes 8 0x00000000c1000000 0x00800000 AGP 0x00 0x0000000000000000 yes robert. -- Robert Noland <rnol...@2hip.net> 2 Hip Networks
