Updated and Optimized Ubuntu Free Graphics Drivers

[Guest]

It can be either llvm or gallium nine.

that's probably gallium nine though, and testing again when last serie of patches is merged to mesa git can change that.

I went from Paulo's PPA to oibaf's, added the gallium-nine mesa PPA, and the DRI3 PPA, and there wasn't any (severe) flicking in Dota 2 (I noticed a single random flicker in about 40 seconds of gameplay; not sure if it was isolated or if it'll happen more in longer sessions). I'm thinking it's LLVM, but not really sure.

Well, I'm running my own build of mesa, based on oibaf's one, without nine, so I think is related to LLVM.

Did somebody try latest libvdpau/vdpauinfo with gtx 960+ or latest vainfo with broadwell?

Can you add that lower kernel is supported (above 3.13 or 3.14, I'm not sure) if you add to the boot option drm.rnodes=1 That activates render-nodes.

Also perhaps you can add the wine version can be installed via PlayOnLinux.

Sounds great! IMO, outdated LLVM has been most pressing issue recently. Because in RadeonSI absolutely everything relies on shaders, even 2D, and older LLVMs were really crapy in this regard.

Strange, lib has really updated. However, compiled binaries (e.g. OpenCL kernels) contain mention of -rc1 inside of them once they're compiled. Is it just as planned? (e.g. runtime from rc1?)

[oibaf]

Added info about older kernel. About llvm if there are still issues with 3.6-rc2 make sure to open a bug on freedesktop or it will never be fixed.

I think that's just the string of version which was compiled and it's not meaningful, I just forced a rebuild with newer llvm of mesa and libclc anyway.

Yestardays, the comand output was:

Today, the comand output is:

The output "+vgpr-spilling' is not a recognized feature for this target (ignoring feature) ", is missing ..

Thanks.
