I'm curious about how Southern Islands is advancing. I'm sure that there's plenty of development going on, but Phoronix has been uncharacteristically silent about it for a long time. r600 seems to be shaping up nicely though. Great work Marek and all the other devs out there working on it!

Originally posted by Ericg View PostOkay, hence why I asked for your three's input specifically haha. Just out of curiousity, what is it that you don't like about the kernel's release style? Things seem fairly stable even during RC's (im running 3.8rc3 right now, before I ran rc1)
Ever since 3.0, from my perspective, the kernel went to hell in a handbasket...
Around 3.0 is where the kernel platform drivers broke my wireless in my 7 year old HP laptop which was working perfectly fine for 6 years until then.. I've had to blacklist the HP platform driver to fix it.
They tell me to test the latest kernels (3.5 head, 3.6 head, etc.), but these kernels lock the system hard on the same laptop, so they won't even boot. The only solution that works perfectly is kernel 3.2 in Debian Wheezy and on top of that, I have to blacklist the HP platform drivers. If I do that, the system is rock solid stable and the wireless works flawlessly. it's also works flawlessly on 2.6* and 2.4* kernels since forever..
Then I bought a new laptop.. Turns out Kernel 3.2 that works perfectly on my other laptop, in Debian Wheezy, randomly locks up hard when running iceweasel/firefox on this new laptop. In fact, it seems to be a common occurance for people with mobile Ivy Bridge processors and intel graphics. I'm so lucky that the 3.5 head and 3.6 head kernels actually boot in this new laptop (although they don't on my other), and not only that, but it fixes the lock ups.. Why haven't the fixes in 3.5/3.6 been backported to 3.2 stable? I have no f-ing clue. Apparently the kernel team is leaving it to the poor folks at Debian to find these crash fixes in the mess of the 3.5/3.6 kernels and backport them in the hopes of making a stable kernel themselves because the kernel team isn't providing a stable 3.X release (yet!).. IMO, it feels like the kernel is a horrible mess right now. I've got 2 laptops that require very specific kernel versions (that are different!!!) to function at all, which means to me that the whole 3.X series is terribly unstable.Last edited by Sidicas; 13 January 2013, 11:23 PM.

I get the benefit of a nice steady 6month release schedule but something like the graphics stack-- like the kernel, I feel like needs to be a little more rapid release. This way if a feature isn't quite ready, its not a big deal to just release a month and a half or 2months later. The piglit tests help to ensure we don't regress and break things so its not even an argument of "Rapid release means rapid breakage!"
Any input from Kayden? Airlied? Marek?
In my limited experience with working with the kernel and X server, it seems like the kernel process almost necessitates a person whose entire job is managing releases, merge windows, and so on. This makes sense for a huge project like the kernel, but it seems a high cost for us. A similar issue we have is stable branch maintenance---I know Ian has spent a huge amount of time on that, and could spend even more. (Recently, Andreas stepped up to manage that, which has been extremely helpful. We're very grateful!)
Piglit tests are definitely a huge help in mitigating regressions, but they're by no means foolproof---there are still huge gaps in our test coverage. Also, we don't yet have a system set up where we're running those tests on every platform, so they mostly get run on developers' machines. (We should fix that.) I've definitely fixed a number of 965GM crashers right before release that somehow no one had noticed. And especially these days, breaking people's 3D drivers can be pretty painful. I know distros are really concerned about that (and rightly so).
I do agree with Marek---Mesa master tends to be fairly stable and works most of the time. Breakage does happen, but it's usually caught and corrected fairly quickly. I think for advanced users who enjoy being on the bleeding edge and want the latest and greatest, using Mesa master is a decent option. It's reasonably easy to do these days, and we definitely appreciate the additional testing and feedback. But not everybody wants to be on the bleeding edge.
That said, it's very likely that we'll continue evolving the release process. Maybe we'll move to a shorter release cycle in the future. We'll have to wait and seeFree Software Developer .:. Mesa and Xorg

One would hope though that an exception could be made, just this once if OpenGL3.3 support can be had so that either the coming window is pushed back to include it or a special release that adds only that is put out in the interim for the distros to pick up so we aren't waiting till the 2014 releases before we see it.

Well you can use RBDoom3BFG natively. Just without bink videos but it should require the same extensions. Would be a really good test. Running Rage via wine is usally no problem as well when you use binary drivers (for amd you would need 12-11 beta at least).

I shouldn't have gotten a HD7xxx board. I had (falsely) assumed at least fglrx would work.

OTOH having an APU with a discreet card was a PITA to get running. Proof :
