[PATCH 00/10] plugin and tcg cleanups to cputlb.c.

Posted by Richard Henderson 1 year, 3 months ago

Based-on: 20230826232415.80233-1-richard.henderson@linaro.org
("[PATCH 0/3] softmmu: Use async_run_on_cpu in tcg_commit")

Remove the SaveIOTLB hackery, now that the flush won't happen
until the TB.  Clean up the locking, so that we don't try to
take the lock twice.  Clean up the iotlb lookup so that we only
perform it once per page, rather than for each aligned piece.
