Hi all, During my quest for improved performance in such goodies as xine and vlc, I came across the fact that currently on PPC, the X server eats between 20 and 40 percent of the cpu cycles, whereas on i386 (with GATOS drivers), it just sleeps doing nothing....
Although I found no evidence documented evicende of this, I suppose this is because XFree (plain), although implementing Xvideo, doesn't use the hardware acceleration in the ATI chips, whereas the GATOS drivers do just that. Anyway, I tried to use teh GATOS drivers on PPC; but unfortunately hit two problems: - XFree doesn't autoload the i2c module of which some symbols are referenced by the r128 driver. Solved by adding 'Module "i2c"' to XF86Config-4. - Now the Xserver segfaults on startup. Last lines in the log: [list of available accelerations] (II) R128(0): Acceleration enabled (II) R128(0): Using hardware cursor (scanline 3080) (II) R128(0): Largest offscreen area available: 1152 x 1048 (II) R128(0): Dotclock is 0 Mhz, setting ecp_div to 0 (II) R128(0): Cannot access BIOS: info->VBIOS==NULL. Fatal server error: Caught signal 11. Server aborting The last two '(II)' lines look strange... for comparison, plain debian XF410 looks thus: [list of available accelerations] (II) R128(0): Acceleration enabled (II) R128(0): Using hardware cursor (scanline 3080) (II) R128(0): Largest offscreen area available: 1152 x 1048 (WW) R128(0): Option "power_saver" is not used (WW) R128(0): Option "DPMS" is not used (II) R128(0): Direct rendering disabled (II) Setting vga for screen 0. (II) Initializing built-in extension MIT-SHM etc... Anybody else tried to use GATOS drivers on PPC? FYI, I'm using Debian XF410 out of unstable, and I'm trying out the XF410 GATOS drivers. Help? Ideas where to look? Cheers, and thanks Michel ------------------------------------------------------------------------- Michel Lanners | " Read Philosophy.
