Amd released Rocm 6.4

[arisu]

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.
