Subject: 2.6.9-rc1: scrolling with tdfxfb 5 times slower
Date: Tue, 31 Aug 2004 21:33:40 +0200 [thread overview]
Message-ID: <200408312133.40039.ornati@fastwebnet.it> (raw)
The recent changes in frame buffer code seems to affect performance of
scrolling on my system:
Voodoo Banshee (tdfxfb)
CONFIG:
#
# Graphics support
#
CONFIG_FB=y
CONFIG_FB_3DFX=y
# CONFIG_FB_3DFX_ACCEL is not set
#
# Console display driver support
#
CONFIG_VGA_CONSOLE=y
# CONFIG_MDA_CONSOLE is not set
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
# CONFIG_FONTS is not set
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y
Tests with "linux/MAINTAINERS" (time cat MAINTAINERS)
2.6.8.1
real 0m2.625s
user 0m0.000s
sys 0m2.621s
2.6.9-rc1
real 0m13.528s
user 0m0.000s
sys 0m13.553s
Also many -mm kernels are affected... this is obvious because these patches
come from Andrew's tree ;-)
Any ideas?
