Hi!

...

After update to 3.15-rc2, only top 20% of screen works on X.

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)

00:02.1 Display controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) Subsystem: Intel Corporation Device d614 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Region 0: Memory at d0400000 (64-bit, non-prefetchable) [size=1M] Capabilities: <access denied>

This worked before. I believe it worked in 3.14. It definitely works in 3.11-rc2.

Screenshot or more detailed description of what "only top 20% of screen works in X" means? Anything in dmesg?

Actually yes, dmesg suggests it is quite sick. drivers/gpu/drm/drm_mm.c:767 warning triggered repeatedly. Also.. initial framebuffer does not work ; I don't seem to see anything before X start up. (This is Debian 6.0.9)

Best regards, Pavel

Jiri has been seeing a similar issue creep in during resume, but it is not reliable enough to bisect. Is your boot failure reliable enough to bisect? Also drm-intel-nightly should mitigate this failure and allow i915.ko to continue to load and run X, which would be worth testing to make sure that works as intended.

Oh right, g4x going beserk :( Apparently something changed in 3.15 somewhere which made this much more likely, but like Chris said in Jiri's case it's too unreliable to reproduce for a bisect. We've had this come&go pretty much ever since kms support was merged and never tracked it down.

The bug is https://bugs.freedesktop.org/show_bug.cgi?id=76554

Like Chris said please test latest drm-intel-nighlty from http://cgit.freedesktop.org/drm-intel to make sure that the recently merged mitigation measures work properly. But those won't get your gpu back, only the display and it's only for 3.16. We're still hunting a proper fix for 3.15.

So far I went back to 3.14, and yes, graphics works there.

Back to 3.15, put it to smaller monitor. This time, top 30% of screen works, and last working scanline is copied to the rest 60% of screen. [With the exception of mouse cursor, that somehow affects that magically.]

So you know where the bug is or not?

No, but there is a workaround for cases kernel finds out that it cannot execute GPU commands (because the rings failed to initialize), and instead it falls back to CPU rendering directly into the framebuffer.

So it's highly sub-optimal, but works around the complete wreckage.

What does it means "won't get my gpu back, just my display"? Gpu is the thing driving the display... no?

We think of it as discrete functional units, i.e. the display engine is separate from the GPU. What happens here is that the render engine doesn't respond to our commands to set it up, but that should not prevent us from setting the register values in the display engine to drive the actual outputs.

I checked out drm-intel-nightly. Now I can see some kernel messages scrolling around on vga console (improvement?), but then end up with completely blank screen, and dead machine, AFAICT. Can't seem to ping it.

Eeek. Do you have netconsole handy? -Chris

Hi!

Ok, it was not as painfull as I feared.

It does not revert cleanly, but doing it by hand was not that bad.

drm/i915: disable rings before HW status page setup

Rings should be idle before issuing sync_flush (in intel_ring_setup_status_page). This patch moves the ring disabling before doing the HW status page setup.

No, I don't have that one.

To confirm, on drm-intel-nightly you used a patch like:

I did not use drm-intel-nightly, but 3.15-rc2, because drm-intel-nightly did not work at all. (Netconsole is not that easy to set up, and I'd prefer not debugging 2 problems at the same time.)

Let me check with my patch reverted and 9991ae applied.

Yes, with that commit, graphics is back to working state. Please push it to mainline soon -- it fixes a regression. Feel free to add

Alright, most of my testing has been done with that commit present (obviously, as I've been using Chris' branch that has this incorporated), so I have a different ring initialization problem than Pavel had.

Actually, I'm not using modules -- everything is build-in. Can you try that config? Perhaps you can then reproduce the failure.

So far it failed 100% of time, but this is my main machine, so bringing it down for extended periods is no-no.

Greetings to Prague :-). Jiri, do you have i915 a module or build-in?

Hi there Pavel, long time no see :)

I have i915 built as a module.

The thing is, that I can't really bisect this; the problem is, that I've started seeing this quite a long time ago, but only very sporadically (something like once in 40 resumes). But it was getting gradually worse and worse with newer kernels, and with current tree (both Linus' tree and drm-intel-testing), I am getting it 100% reproducibly on every resume.

This makes bisection completely impossible though.
