[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3031 has been updated by daftaupe.

Status changed from In Progress to Closed

@ftigeot pushed the following commit https://gitweb.dragonflybsd.org/dragonfly.git/commit/4be47400997875399098ad904fb4ca65b3244cca which brings drm/radeon version to the one of Linux 4.10.17.

I'm closing as we now have a more recent version in base.

Sometimes one must go backwards before one can go forwards.  The attached patch updates drm/radeon to Linux 4.7.10 as much as possible, with the obvious exception of patches related to dma_fence, reservation objects, dma_buf, prime, DisplayPort MST, and interval trees.  In particular, because I do not have DisplayPort hardware to test, I expect complete breakage.

When I want decent font display without corruption on a CAICOS Sapphire Radeon HD6450 card, I use in a hacked version of pkgsrc for mesa 17 in /usr/pkg/share/X11/xorg.conf.d a 20-glamor.conf file resembling:

<pre>
Section "Module"
    Load "dri2"
    Load "glamoregl"
EndSection
Section "Device"
    Identifier "Radeon Graphics"
    Driver "radeon"
    Option "AccelMethod" "glamor"
    Option "ShadowPrimary" "on"
EndSection

</pre>

Take out the Option "ShadowPrimary" "on" and there are quite visible artifacts, but I am still able to fire up firefox using

@LD_PRELOAD=/usr/pkg/lib/libGL.so firefox &@

with layers acceleration forced to get some sort of display in WebGL Water:

The patch is radeon47fast.patch generated by git format patch.  Also attached is a diff between drm/radeon after the patch compared to Linux 4.7.10's.  radeon_4_07.diff shows exactly what is left to be done.

The patch seems to apply cleanly up through at least

<pre>

Date:   Mon Apr 24 19:22:39 2017 +0200

    <fcntl.h>: Add some missing defines (required by POSIX).
</pre>
