[Qemu-arm] [PATCH v9 24/25] target-arm: ensure all cross vCPUs TLB flushes complete |
|
Date: |
Wed, 1 Feb 2017 15:05:52 +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_synced() 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.
