Intel Extreme driver is not loading.

[Bouncer]

My Acer 7750 laptop - simply refuses to load the Intel Extreme driver. It always boots with the VESA driver, and denies me the high resolution I expect.

'listdev' shows the following - so I know the 'Intel Extreme' is there.

device Display controller (VGA compatible controller, VGA controller) [3|0|0]
  vendor 8086: Intel Corporation
  device 0116: 2nd Generation Core Processor Family Integrated Graphics Controller

In the Syslog file - the intel_extreme driver stops after the message: "error: could not map GART aperture!"

I am attaching the lisdev and syslog files.

I have tried to research this - and it seems similar to the very old ticket #1969

I tested this with a GCC4 compile of hrev 45814. On a ACER 7750 laptop (i7, HD3000).

Is it a GCC4 32bit build?

[Bouncer]

Yes - a GCC4 32bit build. But not a Hybrid. Cross compiled on Ubuntu Linux.

In case there is any question, my BTools is at btrev43508.

Could you activate tracing in src/add-ons/kernel/busses/agp_gart/intel_gart.cpp line 17, build "<agp_gart>intel" and update this module? You'll see there are not many possible failure cases: not found bridge, memory allocation or mapping failures.

I tried activating tracing as you suggested. The only new information is that the "could not map GART aperture" error occures immediatly after a a line showing "agp-intel: bus manager init"

I will attempt to attach the new syslog.

By the way. I also tried a test using the latest nightly (gcc2-hybrid 45817). I get the exact same error as shown in my gcc4 compiles.

gcc4 hrev45817 tracing enabled in "intel_gart.cpp"

OK then the probing phase failed because it should have displayed "found intel bridge". Could you have a try with hrev45822?

[Bouncer]

Success! Haiku now loads the Intel_extreme video driver. I am now setting higher video resolutions. Thanks!

Thanks for the feedback!
