Intel Extreme Driver Does Not Work With Intel Atom D510

[atomozero]

work only vesa mode :(

device Display controller (VGA compatible controller, VGA controller) [3|0|0]

vendor 8086: Intel Corporation
device a001: N10 Family Integrated Graphics Controller

KERN: intel_extreme: init_hardware()

This uses the GMA 3150 which should be similar to GMA 3100.

Adding in device id might get intel_extreme driver to work with this graphic chip.

Simply adding the deviceid to the intel_extreme driver and agp_gart did not seem to work. Seems to end up at a black screen with my monitor complaining about a bad video mode.

I'll send $25 USD via paypal to anyone who can get intel_extreme to work and provide native resolution support on the N10 graphics chipset (deviceid 0xa001) of my Atom box. Consider this a "mini-bounty" of sorts - or at the very least, a thank you gift :)

The GMA3150 is integrated with the Atom. The N400 and D4/500 datasheets at (1) contain some information about the GMA3150 control register, which seems to be compatible to the G33's.
The changeset that adds support for the GMA3150 to the Linux driver can be found at (2). This might contain some hints as to what needs to be changed.

Applied locally, looks like a few constants were missed:

/home/umccullough/haiku/haiku/trunk/src/add-ons/accelerants/intel_extreme/mode.cpp: In function `void retrieve_current_mode(display_mode &, long unsigned int)':

/home/umccullough/haiku/haiku/trunk/src/add-ons/accelerants/intel_extreme/mode.cpp:963: parse error before `)'

I'll see if I can clean that up and test it a bit.

Fixed version of brecht's patch, missing constant values added from linux driver

[umccullough]

Oops, did you update the patch as well?

Using the version of the patch I just attached here, it compiles (there were some syntax issues as well), but it produces a black screen on boot still, and my monitor claims the mode is wrong.

If I get a chance, I'll locate my serial cable and provide some debug output.

[brecht]

Can you provide the output of the following:

setpci -v -d 8086:a001 10.L
setpci -v -d 8086:a001 18.L
setpci -v -d 8086:a001 1C.L

You can find setpci ​here.

[umccullough]

Results are here:

~/Desktop> setpci -v -d 8086:a001 10.L
0000:00:02.0 @10 = fea80000
~/Desktop> setpci -v -d 8086:a001 18.L
0000:00:02.0 @18 = d0000008
~/Desktop> setpci -v -d 8086:a001 1C.L
0000:00:02.0 @1c = fe900000
~/Desktop>

fixes some bugs in the PLL code

[brecht]

The new patch fixes some errors I made in porting the Linux driver code. There's probably more left, though. Please attach your syslog using the current patch.

[umccullough]

Will test tonight - and if it works, you'll need to send me the email address you use for PayPal privately :D

[umccullough]

Wonderful - it works! :)

I'm posting this comment from my Atom D510 machine using 1920x1200 and the intel_extreme driver...

I tested GLTeapot and a couple resolution changes, but I did not test media player/overlay support since I didn't have any videos handy.

syslog and screenshot coming shortly.

Brecht, I (gladly!) owe you $25 :)

syslog after successful boot with intel_extreme and Intel N10 support

Screenshot showing the details

The naming is a bit inconsistent (DISPLAY_PLL_IGD_POST1_DIVISOR_MASK vs. DISPLAY_PLL_N_DIVISOR_MASK_IGD -- the latter should be DISPLAY_PLL_IGD_N_DIVISOR_MASK instead), but the rest looks like the necessary evil. Nice work Brecht!

[brecht]

Patch with consistent naming is applied in hrev40319.

thx!!!! ^_
