Summary: Driver "radeon" lacks importand 2d accelleration on
r350 [1002:4E4A, ATI FireGL X2 NK (AGP)]
Product: xorg
Version: 7.6
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
AssignedTo: [email protected]
ReportedBy: [email protected]
QAContact: [email protected]
Testcase: Open up an xterm, start a screen session with a few windows
(actually, two windows are enough) and then cycle around the windows. It's
awfully slow. BTW: Running the same screen on the linux console (radeondrmfb)
yields fast results.
The most CPU cycles are burned in
* fbGlyph32 (by fbImageGlypgBlt by ExaCheckImageClyphBlt by damageText by
damageImageText16 by doImageText by ImageText by ProcImageText16 by Dispatch)
* memcpy (by RADEONCopySwap by RADEONDownloadFromScreenCS (and others) by
exaCopyDirty by exaCopyDirtyToSys (and others) by exaPrepareAccessReg_mixed by
exaPrepareAccess by ExaCheckImageClyphBlt [and so on, see above])
Would be nice to have this function use 2D accelleration - it's really
important for usability.
Regards, Bodo
PS: If you need dmesg, etc just ask, xorg.conf is same as in bug #35196
