[Bug 564378] Re: Fails to set MTRR for 2D acceleration
apport information
** Tags added: apport-collected
** Description changed:
Binary package hint: xserver-xorg-video-neomagic
Playing DVD or other video results in dropped frames and high CPU usage
on a Neomagic NM2380 chip (MagicMedia 256XL+). The problem is evident in
VLC and Totem. This was not the case in Hardy. The difference has been
traced to the absence of the MTRR setting for video acceleration. This
bug also exists in Jaunty and Karmic but I have not tested Intrepid.
In Lucid (10.04):
cat /proc/mtrr
reg00: base=0x000000000 ( 0MB), size= 256MB, count=1: write-back
reg01: base=0x010000000 ( 256MB), size= 128MB, count=1: write-back
In Hardy (8.04):
cat /proc/mtrr
reg00: base=0x000000000 ( 0MB), size= 256MB, count=1: write-back
reg01: base=0x010000000 ( 256MB), size= 128MB, count=1: write-back
reg02: base=0x0fc000000 ( 4032MB), size= 8MB, count=1: write-combining
Entering the command
echo "base=0xfc000000 size=0x800000 type=write-combining" > /proc/mtrr
in a terminal will set the MTRR but it will be reset at boot or when the X-server is restarted.
