Re: Amd released Rocm 6.4

I'm not noticing any performance improvements, but no regressions either. It seems solid enough. The only difference I see is that it's calling some new ioctl that I've never seen before, _IOC(_IOC_READ|_IOC_WRITE, 0x4b, 0x2, 0x60) which is apparently a new AMDKFD_IOC call.
However I'm also seeing less interference with day-to-day graphical tasks. I haven't had any crashes when switching virtual terminals like I did with 6.2.3 but it is possible that it is only coincidence.
Edit: Hasn't eliminated the issue with amdgpu crashing so I guess that is 100% on amdgpu's side and is not something that ROCm is doing to it. But it's not worse anyway and it doesn't interfere with folding, just GUI tasks.
