Intel GPU kernel driver

[Andrey Kosachenko]

Hi, Konstantin,

First of all thanks for time and efforts you've spent on the challenge 
in question!

I tried to test patches (actually at the moment of writing the latest 
one is all.4.1.patch) on my laptop (Lenovo ThinkPad T410) with 
integrated Intel graphics card (Ironlake, 0x00468086).

To make a long story short, basically it works over here (saying that I 
meant X server comes up, LVDS operates in native resolution 1440x900, 
didn't notice any issues with typical desktop applications (text 
editors, xterm, browser (flash is played smoothly) and so forth)).

I do really understand that this is pretty early stage of the project, 
so I did not expect working composite effects and stuff like that 
(actually I tried desktop effects but X segfaults:

so turned it off.


Anyway things I saw definitely made me think about withdrawal of laptop 
from my girlfriend (who I granted it nearly a year ago since it was not 
operational under freebsd) ;).

So far I'd like to admin 2 issues:

- switching between vts (Ctrl+Alt+F[1-9]) doesn't work over here, 
attempt to switch to consoles within range [1-8] leads to garbled screen 
(https://lh4.googleusercontent.com/-WmDhn1X-Ze0/Thn-O5dfeiI/AAAAAAAAABM/WIX3co3DQaM/s720/20110710_003-1.jpeg) 
though 9-th (occupied by X) is always displayed properly;

- attempt to play video (by means of vlc) freezes machine completely. I 
hasn't spotted it yet (system is installed in zfs and there is no 
freebsd-swap partition, so I didn't manage to make savecore leave smth. 
for further investigation);

PS:
I didn't mention any listings (pciconf,dmesg,...) however if those 
considered to be useful/helpful just let me know.

thanks!
