--- Comment #14 from Ignacio R. Morelle <[email protected]> 2010-12-31 18:17:19 PST --- I have just made a rather odd discovery using current master HEAD DDX, latest Mesa from git master on Linux 2.6.37-rc8, X.org server 1.9.3 RC-2 from Debian experimental (1.9.2.902). The bitmap font I prefer for Konsole is Terminus, and it comes in a few fixed sizes such as Regular 9, Regular & Bold 11, Regular & Bold 12. I used to run Konsole using Terminus Bold 11 until a few days ago, when I figured out that it messed up the TrueType fallback for characters not in Terminus' glyph set such as Japanese hiragana. I now use Terminus Bold 12 instead, which seems to work with the aforementioned characters fine -- and this night I decided to give the latest DDX revision a try to see if the drm/radeon changes in Linux 2.6.37 could make a difference regarding this current bug. It turns out that X will use less than 10% CPU while idle [*], just like with Terminus Bold 11 with the DDX revision previous to commit f8fb9312d791af1f77020e8c2d35bb30841ed9aa "RADEONPrepareAccess_CS: fallback to DFS when pixmap is in VRAM". Performance drops again if I switch back to Terminus Bold 11, CPU usage sky-rocketing above 50%. I can't perceive much difference between both font sizes other than line spacing. Perhaps this has something to do with this bug -- overlapping glyph regions maybe? I'm not sure if this contributes anything to the possibility of fixing this bug, but I thought I'd mention just in case. [*] "idle" here stands for a maximized Konsole window on a 1280x800 display with 'top' running on foreground in the active tab. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
