            Bug ID: 78453
          Assignee: dri-devel at lists.freedesktop.org
           Summary: [HAWAII] Get acceleration working
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: luziphermcleod at yahoo.ie
          Hardware: Other
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

Hawaii acceleration is currently disabled by default, as it doesn't really work
(causes GPU crashes). This bug intends to collect data that hopefully helps to
resolve the issues.

agd5f suggested on irc that, when hawaii support was first commited, it worked
better than now. Back then, glxgears worked according to his words. He also
said it'd help to know which component caused the regression for glxgears. I
tried to get glxgears working with software versions from back then, but I
wasn't succesful.

The information I collected so far is:

#### A: OLD (mostly from the time when hawaii support was commited first) ####

    - keyboard doesn't respond (caps-lock doesn't change led, ctrl-alt-F#
doesn't change to console)
    - short press on power button on computer works (screen stays frozen, but
system shuts down after a few seconds)

#### E: Updated glamor, xf86-video-ati, xorg-server, libdrm, mesa ####
xf86-video-ati: 0333f5bda27dc0ec2edc180c7a4dc9a432f13f97

libdrm: git (2014-05-07), 2.4.54 series
----> Result when statring "Xorg -retro":
    - X starts as expected (low resolution, pattern an mouse visible)
    - remotely running glxinfo gives output (radeon driver) but crashes X
    - glxgears shows a correctly rendered frame, stalls, gpu crash shortly
afterward (black screen). See attached video for details
    - the gpu crashes continue, the screen get's more and more corrupted
    - when killing glxgears (from remote), the computer crashes completely
    - also see attached logs
