    i965/miptree: Use the correct BLT pitch

    Retile miptrees to a linear tiling less often. Retiling can cause issues
    with imported BOs.

Comment 1 Andrés Gómez García 2018-07-24 12:22:15 UTC 
Dylan already spotted other regressions at:

https://lists.freedesktop.org/archives/mesa-dev/2018-July/200703.html

And Nanley provided a fix at:

https://patchwork.freedesktop.org/patch/240418/

But I've, checked, and the regressions are still there.
Comment 2 Andrés Gómez García 2018-07-24 12:23:27 UTC 
Forgot to mention, the regressions are tested against a docker image in which there is a running X server. I can provide the image in case it is needed.
Comment 3 Andrés Gómez García 2018-07-24 12:24:17 UTC 
Also, forgot to mention that the tests are passing for all the other CTS configurations.
Comment 4 Mark Janes 2018-07-24 18:11:37 UTC 
these tests pass for me on KBL.  This is surprising, because generally KBL/SKL have identical results on all test suites.
Comment 5 Nanley Chery 2018-07-24 19:01:06 UTC 
The tests pass for me on SKL (with the patch on the list). Could you provide more information about your setup?

Ugh! This is getting tricky.

I've created an Ubuntu Xenial based docker image that you can use. You can try directly with:

--

$ docker run --privileged -t --rm -e DISPLAY=unix$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix igalia/mesa:vk-gl-cts.opengl-cts-4.6.0.cl.nanley-fix-upstream /bin/bash -c "export MESA_GLSL_VERSION_OVERRIDE=460; export MESA_GL_VERSION_OVERRIDE=4.6; cd /home/local/vk-gl-cts/build/external/openglcts/modules; ./glcts --deqp-case=KHR-GL46.texture_barrier.disjoint-texels --deqp-screen-rotation=unspecified --deqp-surface-width=-1 --deqp-surface-height=64 --deqp-watchdog=disable --deqp-base-seed=3 --deqp-gl-config-name=rgba8888d24s8 --deqp-surface-type=fbo --deqp-gl-config-id=1 --deqp-gl-context-type=egl"

--

Or, if you want to get into the image and see what's going on ...

--

$ docker run --privileged --rm -it -v $HOME/.ccache:/home/local/.ccache:Z -e DISPLAY=unix$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix igalia/mesa:vk-gl-cts.opengl-cts-4.6.0.cl.nanley-fix-upstream /bin/bash

Mesa source code is at /home/local/mesa and is quite close to current master. Latest commit is "b3b170ade9cc3abe6b861a549292c9ec230844bc" and, then, your proposed fix on top.

VK-GL-CTS source code is at /home/local/vk-gl-cts, using the "opengl-cts-4.6.0" branch. Latest commit is "7e3cd2412d640ca8e8e1db9362c32e75a91d5235".

You will need a running X server in the host system. Mine is a Debian Testing with Linux kernel 4.16.0-2-amd64, xserver-xorg-core 2:1.20.0-3 and xserver-xorg-video-intel 2:2.99.917+git20171229-1+b1.

Notice that the "local" user inside the docker image has uid 1000. That is relevant, at least, for the mounted ccache directory in case you want to compile something.
Comment 7 Nanley Chery 2018-07-27 19:00:11 UTC 
I was able to reproduce the issue in the docker image and on my BDW NUC running Arch. 

The issue is present for width sizes 16383px and 16384px specifically.
Comment 8 Nanley Chery 2018-07-27 23:05:02 UTC 
A fix is on the list: https://patchwork.freedesktop.org/patch/241419/

This has been tested to work on BDW. Does this fix the issues on your SKL?
Comment 9 Andrés Gómez García 2018-07-30 16:27:11 UTC

Tested, and I can confirm this patch fixes the problems listed for SKL and BDW.

Great job, Nanely! :)
Comment 10 Andrés Gómez García 2018-08-09 10:33:03 UTC 
Ugh! Unfortunately this patch is causing other regressions in GTF tests in SKL:

I've been able to test this (v2) series and I can confirm the problems have gone away.

I hope to be able to check v3 by next week but, if there are not real changes from v2, it's good to go.
Comment 14 Nanley Chery 2018-08-22 20:57:22 UTC 
The 3-patch series has been pushed upstream. The ending commit is:

Thank you for the bug report.

Just FTR, I can confirm the landed v3 3 patches series has corrected the regression.
