Intel(R) GMA 950 doesn't work with Intel Extreme driver and with Vesa driver.

[walera]

My notebook Quanta SW1 with Intel 82945GM chipset and integrated Intel GMA 950 graphics. I try install different versions of Haiku from Alpha 2 to hrev46656 but by use intel_extreme driver (default loading from installation CD) I see colors noice on LCD screen. If I choice fail-safe video mode (I try all modes) I see black screen only but I hear loading from CD. Resolution of integrated LCD screen is 1280x800. I make my tests with external D-SUB monitor also but result was identical.. I try loading from Zeta 1.21 CD also. Zeta doesn't work in VESA mode also but can work in monochrome B/W mode. I make listdev command under Zeta (see attachment).

This looks like the intel_extreme driver didn't manage to allocate enough memory for the framebuffer. A syslog would be useful, if you manage to extract it.

But I see problem in VESA driver also.

I make bootable USB flash and extract syslogs in two loading modes: default loading (intel_extreme driver) and by loading in VESA mode. See attachment.

Things look fine on the video driver initialization and mode setting side. However I noticed this:

There seem to be not enough MTRRs to set the complete memory caching map somewhere during video init, then the problem goes away as a range is unmapped.

Is this a 64-bit machine? I think in 64-bit mode, a better system can be used for setting this, avoiding the limitation. If it isn't, maybe we'll have to fix our MTRR allocation code again.

[bonefish]

The MTRR code is fine. It can ignore uncacheable ranges, since that property will still be enforced via the PTE flags.

This machine support 64 bit OS. CPU - Intel® Core™2 Duo Processor T7200, RAM - 4 Gb. Win7 64 bit work on this computer w/o any problems.

I make new test - remove 2 Gb RAM module. After it Haiku loaded w/o any problems. See new syslog in attachment.

There have been a lot of fixes to the Intel video driver in the past 3 years. Could you please retest?

I'm having similar issue with a left margin added (and right side of screen is out-of-bounds/hidden).

You seem to have a different problem though? This ticket is about black screen on boot.

[hey68you]

But I do have the color noise :)

In any case, I think you (on IRC) once pointed me to an different open ticket with a similar issue... please let me know if you can find it and/or should I open a separate new bug?

[waddlesplash]

Please retest after hrev53040.

[waddlesplash]

Color noise is indeed a separate ticket, so if there is at least output, this ticket is fixed.
