Subject: [Qemu-devel] [PATCH RFC v1 0/3] Enable MTTCG on PPC64
Date: Thu, 6 Apr 2017 15:52:46 +0530

The series enables Multi-Threaded TCG on PPC64

Patch 01: Use atomic_cmpxchg in store conditional
      02: Handle first write to page during atomic operation
      03: Generate memory barriers for sync/isync and load/store conditional

Patches are based on ppc-for-2.10

Tested using following:
./ppc64-softmmu/qemu-system-ppc64 -cpu POWER8 -vga none -nographic -machine 
pseries,usb=off -m 2G  -smp 8,cores=8,threads=1 -accel tcg,thread=multi  f23.img

* Enable other machine types and PPC32.
* More testing for corner cases.

Nikunj A Dadhania (3):
  target/ppc: Emulate LL/SC using cmpxchg helpers
  cputlb: handle first atomic write to the page
  target/ppc: Generate fence operations

 cputlb.c               |  8 +++++++-
 target/ppc/translate.c | 29 ++++++++++++++++++++++++++---
