Subject: [Qemu-devel] [PATCH RFC v1 0/3] Enable MTTCG on PPC64
Date: Thu, 6 Apr 2017 15:52:46 +0530 [thread overview]
Message-ID: <20170406102249.20383-1-nikunj@linux.vnet.ibm.com> (raw)
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
Todo:
* 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
