RADEONHostDataBlit. - Disable the shortcut for switching from 3d to 3d in radeon_exa.c. It appears that we do need the cache flush here, thought it's not clear why. Disable the 2d to 2d shortcut while here, since I'm unsure of what we're doing. Exposed by the following bit: - Bug #4485: Add a new routine, exaGlyphs, to handle font drawing. Glyphs were being accumulated in from non-migratable scratch pixmaps, causing the destination pixmap to move towards screen but the migration necessary for source never to happen, leading to abysmal performance. Instead, copy the scratch glyph data into a real pixmap first, then composite from that into the destination, allowing for migration. time ls -lR from programs/Xserver showed 26.9% (+/- 6.3%) decrease in wall time (n=3). - Create exaDrawableUse* wrapping exaPixmapUse*, but which are aware of windows needing backing store. Makes migration code prettier, and ensures that composited windows will be migrated as normal when we turn off cw for EXA. (issue brought up by keithp) |
