|
|
I have an r600 based (RS780) GPU. I've been updating my USE flags, kernel and configuration and am pretty happy with what I have.
Recently, DRI3 capability has been released for the ati/amd series GPUs. However, it is not enabled by default. I'd like to enable DRI3 (for testing) which I inderstand I need to set in xorg.conf. However, I can't find anywhere examples of what this xorg.conf section is supposed to look like.
And of course, given the recent timing of the release, mention of enabling DRI3 isn't included in any 'How-To's either.
Currently, I don't use an xorg.conf file so I assume I just need to create one which only has the DRI3 section enabled to do this.
2nd question. If I want mesa to build a mesa driver for only r600 GPUs, do I do the same type of thing as I would do for an Intel i915 series GPU? i.e VIDEO_CARDS="radeon r600"? I don't expect any functional differences. I'm just like to not include things I won't use.
For what it's worth, this is my pertinent installed packages/configuration/capabilities: Code: | Portage 2.2.18 (python 2.7.9-final-0, default/linux/amd64/13.0/desktop/kde, gcc-4.9.2, glibc-2.20-r2, 3.19.2-gentoo x86_64)

So far, DRI3 is enabled, working and everything seems noticably faster. I don't know if that last is real or wishful thinking on my part, but everything really seems to display noticably faster.
Note: I use xf86-video-ati-9999 from the Gentoo X11 overlay and I updated to the 3.19.3 gentoo-sources kernel just prior to activating DRI3. The rest of my configuration remains as I posted above.
I've been using my system as normally would which includes assorted new anime playback, some experimental Hi444p video playback and so forth. No 'gatchas' yet.
Thank you again Perfect Gentleman. _________________ People whom think M$ is mediocre, don't know the half of it. |

DRI3 seems to be on by default on my i915, I wonder why we have to jump through hoops for it on radeon (and why "Option DRI3" isn't documented anywhere...) |

DRI3 v2 was included in the radeon driver only 2 weeks ago. Code: | 12 days Add xorg_list_for_each_entry_safe fallback in radeon_list.h Michel Dänzer 1 -0/+1
12 days Simplify includes in radeon_{dri3,present}.c Michel Dänzer 2 -16/+2
12 days Add DRI3 support v2 Michel Dänzer 6 -3/+236
12 days Handle tiling in radeon_set_shared_pixmap_backing David Heidelberger 3 -4/+41
12 days Add support for the Present extension v2 Michel Dänzer 5 -3/+431
12 days Add support for SYNC extension fences v2 Michel Dänzer 5 -2/+165
12 days Fold radeon_glamor_flush into radeon_cs_flush_indirect Michel Dänzer 3 -20/+11
12 days Move #include "radeon_glamor.h" from radeon.h to where it's needed Michel Dänzer 8 -35/+43
12 days DRI2: Split out helper for getting UST and MSC of a specific CRTC Michel Dänzer 3 -20/+40
12 days DRI2: Use helper functions for DRM event queue management v3 Michel Dänzer 4 -236/+166
12 days DRI2: Move radeon_dri2_flip_event_handler Michel Dänzer 1 -58/+58
12 days DRI2: Remove superfluous assignments to *_info->frame Michel Dänzer 1 -6/+0
12 days DRI2: Simplify blit fallback handling for scheduled swaps Michel Dänzer 1 -27/+20
12 days Add DRM event queue helpers v2 Michel Dänzer 4 -2/+244
12 days Move xorg_list backwards compatibility to new radeon_list.h header Michel Dänzer 3 -9/+40
2015-03-05 Require at least xserver 1.8 Michel Dänzer 2 -30/+6 |
I did see either a 'one time' emerge notice or a gentoo mail notice specifying that while DRI3 for radeon was now included, it was by default not enabled. I believe the idea was to not break unsuspecting users if there were any unnoticed bugs.
Since the lag in the radeon driver for DRI3 support applies only to radeon and that some time in the future it will be enabled by default, the notice I saw flash by was probably considered all that was needed.
The xorg.conf section segment Perfect Gentleman provided is pretty standard syntax for the xorg.conf file. It's just that I've run for years without an xorg.conf file and couldn't cudgel my memopry hard enough nor find examples to give me the correct naming I needed.
And, BTW - while the driver provides the DRI3 capability, I think it's either xorg-server or mesa which enables DRI3 from the user's perspective. So yes, intel users have had DRI3 enabled earlier. _________________ People whom think M$ is mediocre, don't know the half of it. |
