Hi, Some of these patches have been posted before and previous patches have already been accepted upstream so I'm tagging this as a new RFC series.
This is a series of tests built around kvm-unit-tests but built with the express purpose of stressing the TCG, in particular MTTCG builds. Changes from previous appearances: * Separated locking and barrier tests * Included Drew's IPI patches (used in tcg-test) * New TCG chaining test The new barrier tests really only fails when running on MTTCG builds on a weak backend. Many thanks to Will Deacon for helping me get a working test case at the last Connect. I'm mainly posting these for reference for others testing MTTCG as I've still got to check I've addressed any outstanding review comments. However there has been enough code churn some of the comments may no longer be relevant. The TCG tests are also useful as benchmarks for comparing the cost of having chained basic blocks versus exiting the loop every time. The pathological case is the computed jumps test as all the addresses are within a PAGE_SIZE boundary the tb_jump_cache has no effect meaning a full look up each time.
