I have been using linux for 2 years already. And I use it on intel 915 GM video card on Lenovo laptop. With:
(II) Loading /usr/lib/xorg/modules//drivers/intel_drv.so
(II) Module intel: vendor="X.Org Foundation"
compiled for 1.5.2, module version = 2.5.0
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 4.1
And acceleration module XAA when I watch Xvid movie on full screen, according to TOP:
X uses 4% of CPU
SMplayer 10-12% of CPU.
GLXgear gives me:
3216 frames in 5.0 seconds = 643.117 FPS
Now I tried Fedora13 (test) with intel driver:
[ 27.854] (II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so
[ 27.855] (II) Module intel: vendor="X.Org Foundation"
[ 27.855] compiled for 1.8.0, module version = 2.11.0
[ 27.855] Module class: X.Org Video Driver
[ 27.855] ABI class: X.Org Video Driver, version 7.0
And can you imagine GLXgear gives me:
165 frames in 5.1 seconds = 32.612 FPS
Watching Xvid movie:
X uses ~40% of CPU
SMplayer ~10-20% of CPU.
Even when I switch workspaces X11 uses ~20% of CPU - there is no any 2D acceleration at all
After all of this I would like to ask:
Do you respect customer who use linux?
Does any one check your driver and UXA with i915?
Why, just why developers through away XAA from driver, your UXA works the same as EXA did - awful. Awful with 3D and more important, awful with 2D.
Why dev. can't just leave what was done good for i915?
Why it was necessary to screw everything. Looks like you just put EXA to UXA.
I do not know about other intel chipsets, but i915 works really slow with new and previous driver on UXA.
So, for i915GM new driver is BIG BIG REGRESSION and big step backward.
