jhibbits added a comment to D26600: moea64 Performance improvements.
This is mostly a series of experiments to see what can reduce the locking contention on the 'page pv' lock (PV_LOCK()/PV_PAGE_LOCK()) since those seem to be pretty heavily contended, as measured with lockstat(1).

One last thing: did you try a debug session between the initrd syms setup and pmap_bootstrap() to make sure it doesn't panic due to being unable to access the DMAP?

Fix booke, which doesn't use ifuncs for copyin/copyout. Use a "naked function"

jhibbits added a comment to D15243: Powerpc64: Enable Hardware Transactional Memory.
@kbowling it's available from https://www-355.ibm.com/systems/power/openpower/.
Since PowerISA v3.1, and therefore POWER10, dropped this feature, maintaining only token support, and it's unusably broken on POWER9, dropping this work. Sorry @breno.leitao_gmail.com .
So, HTM is removed in PowerISA 3.1 and it's broken on POWER9. Is it even worth doing at this point? I'm inclined to abandon this.
