Intel HD Graphics Ironlake driver issue

[cocobean]

Usually blacks out screen before Haiku logo boot splash screen appears or before the desktop appears. Normally, desktop screen won't appear unless we use the fail-safe (VESA) graphics driver.

WORKAROUND: Unplug monitor during bootup and reattach after computer fully boots to installer/desktop.

NOTE: Can change screen resolutions under preflet up to 1920x1440 under VESA driver (mentioned in preflet)

Intel VGA output->VGA: works (retested with 1080p monitor)

Main issues: Either I can get past the Haiku logo boot splash screen and it fails to a black screen during screen init, or it just fails directly after I exit the Haiku boot loader menu. Sometimes, I don't get the Haiku logo splash screen at all until it fails to black screen.

With effort, I can get it to load with the VESA driver in which I can modify screen resolutions up to 1920x1440 (I also see this in the boot menu for modifying default screen mode settings).

NOTE: Setting fail-safe driver (true) and using 1024x768x32 @60hz default. Rebooted. This works as a workaround. Screen preflet shows monitor info, monitor dpi, and VESA driver (VESA) in left window pane. Resolutions changeable (when applied) from 640x480 to 1920x1400.

VESA driver/Intel IronLake Graphics reboot test: Rebooting at >1024x768 resolutions seems to crash during boot. Staying at <=1024x768 resolutions seems to boot reliably on Haiku.

Now that the output works reliably through the Intel video VGA output, we can isolate the intel_extreme driver issues better.

NOTE: The intel_extreme driver modeline PLL clock info seems off. See working modeline xrandr output for comparison.

Haiku VESA driver screen preflet info - hrev53365 x86_64

[cocobean]

Tested hrev53556 x86_gcc2.

1. Fail point right after:

   Intel extreme: Found EDID information!!
   (Detailed monitor info appears)
   Post-install script: sshd_keymaker.sh
   Size: 36 cm x 29 cm
   

2. Then, display screen inits to black screen. Fails at point normally where Haiku logo splash screen would appear.

NOTE: I didn't get the crtc info. Also, I get the 'h:' info, but not the 'v:' info after the clock info. Normally, I get the 'h:', 'v:', Maximum pixel clock info, H/V Freq ranges, and crtc info. Also, the full serial number of the active monitor (last four digits appear here).

If the intel_extreme driver can mimic/baseline the VESA driver moreso, this may/should solve the problem as the VESA driver works as expected with this graphics chip.

Please include an updated syslog booting with the driver enabled.

[cocobean]

LiveCD session: I only have recorded video session and screenshots from the online syslog debugger.

[cocobean]

You can close this ticket. I remember seeing that this driver was not intended for the Intel HD series. Possible quick fix is to default all Intel HD graphic chips (Gen 5 and higher) to the VESA driver (i.e. removing them from the intel_extreme driver).

[pulkomandy]

Then let's not close the ticket until that is done.

Tested hrev53790 x86_64; Default settings: No Haiku splash screen, black screen output. Set the default resolution to: 800x600x32 Got the Haiku boot screen. Rocket lit up. Monitor resets. RESULT: Black screen.

If monitor disconnected before bootup, wait 3-5 minutes for full bootup, reconnected monitor. Got blue desktop (success!). So, seems like a sync issue during boot to desktop.

[cocobean]

Intel driver seems to work fine other than the monitor sync issue during boot to desktop.

[vidrep]

The "trick" cocobean outlines above works indeed. I've tried it on 3 PC's so far.

Attached is a screenshot of the Intel driver working at full HD resolution.

[pulkomandy]

The "trick" makes the driver go "oh, there's no display so I will not set up anything". So it's essentially the same as using the VESA driver.

As I mentionned in my forum post and already here in the comments, the intel driver does not work at all for these newer devices currently. Up to sandybridge it's ok, but the later ones we're missing support in the driver.

Syslog for intel_extreme driver- Ironlake test, hrev53790 x86_64

[cocobean]

Hmmm. With Live CD, I turned off monitor, booted CD, let things boot to installer screen, turned on monitor, selected 'Boot to Desktop', screen flashes/init, then it displays the desktop without monitor issues. I'm OK with this for now - versus the safe-mode driver setting or boot menu fiddling.

I'll await further...

[cocobean]

NOTE: Ironlake (Gen5) is BEFORE Sandy Bridge (Gen6). So, it is supported (based on driver info).

[pulkomandy]

Yes, but I don't have an Iron Lake machine here. So I probably missed some things.

SandyBridge and G45 are the ones I can test easily. For the other ones I need to carefully check the registers in the docs.

[ttcoder]

/me guesses he might need to keep an eye on this ticket, for an IronLake/Mobile (instead of IronLake/Desktop as in cocobean's screenshot) laptop that works well in R1/b1 but will get updated to b2.

Syslog for intel_extreme driver- Intel Ironlake GPU test, hrev53864 x86_64

[cocobean]

If I go into Haiku Boot Loader and set the video mode resolution to 1024x768x32, I can get the Haiku splash screen after I continue booting. The screen inits after the rocket icon lights up. Then, stays on a black screen - but finishes booting.

As long as I disconnect the monitor before Haiku splash screen disappears (i.e. after the rocket lights up), I can get a working desktop display. Works good enough for me at the moment.

NOTE: hrev53864 x86_64.
