Latest dports master kills hw accel on i915 and Radeon 4xxx

[davshao]

After using portmaster -d -a to update dports using the latest dports master, various machines running either Intel integrated graphics or using a Radeon 4xxx graphics card no longer have hardware acceleration, instead with xorg using only VESA. Reverting back to dports compiled with the previous set of revisions ending around

drm/i915: Sync intel_ringbuffer.c with Linux 3.8.13

[ftigeot]

The DragonFly-specific patch file graphics/libdrm/dragonfly/extra-xf86drmMode.c has been removed on July 21. I wouldn't be surprised if this is what causes KMS to not be enabled anymore.

[ftigeot]

A fix has been pushed to Deltaports and submitted to the upstream libdrm project.

I removed the extra patch (without looking at it) because it disappeared from FreeBSD. FTR

[ftigeot]

That's all right, FreeBSD folks managed to upstream their patch.

[jrmarino]

is it correct to convert the "extra" patch to an unconditional patch? I thought this patch was applied as a function of DFLYVERSION (based on __DragonFly_version value)

[ftigeot]

The graphics/libdrm port could previously install two different versions of libdrm, the final version beeing choosen depending on the value of the WITH_NEW_XORG variable. The patch was specific to the WITH_NEW_XORG version of libdrm and thus had to be specially handled. FreeBSD ports people have now decided to use a single version of libdrm everywhere; the patch doesn't require special treatment anymore and can just be put into the dragonfly/ directory.

[davshao]

For now hasn't FreeBSD ports simply reverted the change to libdrm? This reversion was done very quickly when they discovered the undesirable effects.

Also I think reverting downgrades the version of libdrm even for kms from 2.4.54 back to 2.4.52.

[ftigeot]

It's not clear what the FreeBSD issue with xf86-video-ati and the old Xorg versions was. Either reverting or updating the port with the patch I put into Deltaports should be fine IMHO.

[jrmarino]

I think I'm going to attempt to put it back how it was before.

[jrmarino]

I'm removing the need for a patch at all by moving the fix upstream (To FreeBSD): http://www.freshports.org/commit.php?category=graphics&port=libdrm&files=yes&message_id=201408020852.s728qWur043045@svn.freebsd.org

[jrmarino]

hopefully this is correct: https://github.com/DragonFlyBSD/DPorts/commit/fe30ac00eb9fefeda35e1d240289637f76f45cf8

Closing with optimism that it is.
