Originally posted by schmidtbag View PostI was thinking the same thing. There must be some DPM issue, these numbers just don't seem right. They're pretty poor even for the 3.12 kernel.
EDIT -- after re-reading Michael's article I didn't see any mention of DPM being forced on (the "enable DPM on CI APUs" patch was Dec 24 and was at the front of 3.14-next rather than the end of 3.13-fixes, which makes sense in hindsight) so that's probably the reason for the slower-than-expected performance.
Hopefully Michael hasn't taken the benchmark setup apart yetLast edited by bridgman; 19 January 2014, 12:59 PM.Test signature

Just a quick caution -- agd5f's drm-next-3.14 branch contains the "make it work well enough that it's safe to enable by default" patches, not just the "enable by default" patch.
Good news is that the benchmark numbers don't seem out of line considering that the Kaveri was probably running without DPM.Last edited by bridgman; 19 January 2014, 01:08 PM.Test signature

Originally posted by bridgman View PostOne last point -- the patches I mentioned in the previous post were for CI in general. I don't think we have explicitly tested DPM on Kaveri yet, although we'll certainly do that next week.
So to me it seems like development slowed done since the dpm and uvd push. More precisely:
- No news about what Christian is working on, his latest state tracker was never merged, I think.
- Marek has almost fewer mesa commits than in his worst exam period.
- No real news regarding Tom ever since bgfminer started working.
I'm not saying they are lazy, quite the contrary. I wonder how restricted they are by AMD legal and other internal stuff (writing reports, god knows)?
Just to give you an example: I've thought that by now r600g will have at least RFC patches to enable GL 3.3 but it appears nobody is working on it.
Yes, I am aware that it wasn't part of your original commitment but if you hire the guys who would do it anyways then I would assume they have more time to work on it.
Can't blame HSA either, there's no news about it coming to Linux any time soon.
Would you be kind enough to enlighten me? Thanks a lot in advance!

As for geometry shaders which is the missing part for OpenGL 3.3, Vadim had started working on them for r600g. Then Dave made a couple of new patches to it. You can find it in one of his branches. As for geometry shaders work for radeonsi AMD is working internally (Alex mentioned somewhere on phoronix). According to RadeonsiToDo, Michel D?nzer is working on it.

It's probably safe to say that everyone is working on what you would like them to be working on, including a few things you haven't thought to ask for yet
