This is just an update with the relevant patches needed to port the v4
of "Slow-path for atomic instruction translation" to mttcg v7.
The full source code is available at the following GIT repository:
https://git.virtualopensystems.com/dev/qemu-mt.git
branch:
slowpath-for-atomic-v4-mttcg
The [PATCH 6/6] is the first step to use runtime helpers in place of the
TCG load/store instructions as suggested by Aurelien Jarno.
The patch-series addresses also some of the Paolo's comments, however
the exclusive bitmap is still using one bit for each vCPU.
Alvise Rigo (6):
cpus: async_run_on_cpu: kick only if needed
cputlb: wrap tlb_flush with the a new function
exec: ram_addr: Fix exclusive bitmap accessor
softmmu_llsc_template.h: move to multithreading
softmmu_template.h: move to multithreading
target-arm: Use a runtime helper for excl accesses
