Hi,
I have a US15W system (z510 atom processor 1,1 GHz and 512 MB RAM)
which is used to display a Flash UI (via the LVDS port)which
eventually renders video and I am using the EMGD 1.14 driver provided
from intel (so not the gma500_gfx from current kernels). Intel
promises video hardware acceleration with this driver as long as one
uses their own flash player plugin, which I use in a 3.6.8 firefox
browser.
The intel documentation says that one must set the following variables
in order for that to work:
Option "ALL/1/General/EnableRegOverride" "1"
Option "ALL/1/General/DispARB" "0x00003232"
Option “ALL/1/General/Xvideo” “1”
And I do, yet when xorg server starts, the EMGD driver disables XVideo
because it claims that a feature called "RenderScale" is enabled and
that using it is incompatible with XVideo and thus turns it off, and
I'm stuck with that...
Does anyone have some experience with this kind of driver/xorg
combination? I really need to accelerate the video via hardware, the
IEGD driver did fine, yet i can't compile that one with a newer kernel
and the emgd drops the framerate to the ground...
