X11 graphics not working in snapshots on Braswell system

Ross L Richardson
>Synopsis: X11 graphics not working in snapshots on Braswell system
>Category: amd64
>Environment:
        System      : OpenBSD 6.5
        Details     : OpenBSD 6.5-current (GENERIC.MP) #131: Fri Jul 19 13:18:29 MDT 2019
                         [hidden email]:/usr/src/sys/arch/amd64/compile/GENERIC.MP

        Architecture: OpenBSD.amd64
        Machine     : amd64
>Description:
        Under 6.5 (release plus syspatches), X11 works with the default
        configuration.  Over the last several weeks, I've been trying
        snapshots, and none has worked correctly:
        - With the default configuration, the box usually switches to screen 4
          but displays nothing, and becomes unresponsive to keyboard, mouse,
          and pings, therefore requiring hard reset.  Without xenodm enabled
          in /etc/rc.conf.local, using
             rcctl -f start xenodm; sleep 120; rcctl -f stop xenodm
          the system survived the most recent test without full lockup.
          See below for relevant logs.
        - Forcing the Intel driver using a configuration file, things do work
          somewhat, but glxinfo/glxgears give errors.
          See below for relevant logs.
>How-To-Repeat:
        Start X11 without a configuration file.
>Fix:
        Unknown.

    drm/i915: Prevent concurrent GGTT update and use on Braswell (again)
   
    On Braswell, under heavy stress, if we update the GGTT while
    simultaneously accessing another region inside the GTT, we are returned
    the wrong values. To prevent this we stop the machine to update the GGTT
    entries so that no memory traffic can occur at the same time.
   
    This was first spotted in

        drm/i915: Remove Braswell GGTT update w/a
   
    However, gem_concurrent_blit is once again only stable with the patch
    applied and CI is detecting the odd failure in forked gem_mmap_gtt tests
    (which smell like the same issue). Fwiw, a wide variety of CPU memory
    barriers (around GGTT flushing, fence updates, PTE updates) and GPU
    flushes/invalidates (between requests, after PTE updates) were tried as
    part of the investigation to find an alternate cause, nothing comes
    close to serialised GGTT updates.

No.  The box still locks up (unfortunately).

Thanks for reporting and trying that.  Nothing else comes to mind.

I've placed an order for a Braswell NUC and can hopefully reproduce and
debug this when that shows up.

I see the same thing.

When using modesetting machine hangs on starting Xorg.
When using intel with sna (default) there is a gpu hang and machine can
be interacted with.
When using intel with uxa machine also hangs on starting Xorg.
