Phoronix: AMDGPU Get More Fixes Ahead Of Linux 4.6 Merge Window

With the big AMDGPU/Radeon feature pull already having been submitted into DRM-Next for merging in turn to Linux 4.6. another pull request was honored this week to land some fixes for the new open-source driver functionality...

When will GCN 1.2 reclocking be enabled by default? Also, when will we see initial Polaris support?

Reclocking is enabled by default in kernel 4.5.

Reclocking is enabled by default in kernel 4.5.

Oh, I thought it was still an experimental feature. Must have mixed something up, I guess.

They changed it very late - not until rc5, i think.

When will Sea Islands (GCN 1.1, CIK) cards support in AMDGPU be considered stable? I heard it works well, but still "experimental". Of course we have RadeonSI for GCN 1.0-1.1, but Vulkan will only support AMDGPU.

It's really a matter of usage/coverage, so I imagine it will stay as "experimental" until we are able to make it the upstream default or have enough coverage from (for example) a major distro enabling it by default sooner. Once that happens I guess radeon support would get marked "experimental"

Note that "stable" is not really the opposite of "experimental" -- one is "how good it works", the other also relates to how actively it is being supported.

[geearf]

How about GCN 1.0? Have you guys decided which way to go ( I mean for Vulkan ) ?

[bridgman]

Still leaning towards extending amdgpu support back to SI unless we run into blocking problems.

Messing with amdgpu now on 4.5rc6 with my 390x, this will be interesting.

EDIT: Yep its a buggy mess...
