GPU Compute / Accelerators / AMD Pro W7xxx series is out folks!

« on: August 04, 2023, 07:29:22 pm »

The RDNA3-based Pro mid range GPU from AMD has been announced.

Both W7500 and W7600 can do AV1 encode/decode and are certified to run pro apps.

I am eyeing the W7500 as it does not require additional power draw. Plus it is a single slot
profile so it might just fit it my tight computer case.

The only thing I am unsure is how well amdgpu in Linux 6.4 or 6.5 supports Navi 33

I have not tried it out yet. I hope it does not break the amdgpu.

AFAIK there ain't much changes related to PowerISA

Operating Systems and Porting / [NEWS] Linux 6.2 brings new qspinlock to bolster large system scalability

« on: December 19, 2022, 10:10:42 pm »

Quote

Up to now IBM Power processors on Linux have relied on the generic queued spinlock "qspinlock" implementation within the kernel but that has been found to cause latency and starvation issues on large IBM POWER10 servers

I don't have enough knowledge to tell if it would benefit the POWER9
