[Qemu-devel] [PATCH v8 24/25] target-arm: ensure all cross vCPUs TLB flushes complete |
Date: |
Fri, 27 Jan 2017 10:39:21 +0000 |
Previously flushes on other vCPUs would only get serviced when they
exited their TranslationBlocks. While this isn't overly problematic it
violates the semantics of TLB flush from the point of view of source
vCPU.
To solve this we call the cputlb *_all_cpus() functions to do the
flushes and ask it to ensure all flushes are completed before we start
the next instruction. As this involves exiting the cpu_loop we need to
ensure the PC is saved before the tlb helper functions are called.
