* checkasm: aarch64: Check for stack overflowsMartin Storsjö2020-05-15
| | | | | | | | | Also fill x8-x17 with garbage before calling the function. Figure out the number of stack parameters and make sure that the value on the stack after those is untouched. Signed-off-by: Martin Storsjö <martin@martin.st>

* checkasm: use perf API on Linux ARM*Clément Bœsch2017-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARM platforms, accessing the PMU registers requires special user access permissions. Since there is no other way to get accurate timers, the current implementation of timers in FFmpeg rely on these registers. Unfortunately, enabling user access to these registers on Linux is not trivial, and generally involve compiling a random and unreliable github kernel module, or patching somehow your kernel. Such module is very unlikely to reach the upstream anytime soon. Quoting Robin Murphin from ARM: > Say you do give userspace direct access to the PMU; now run two or more > programs at once that believe they can use the counters for their own > "minimal-overhead" profiling. Have fun interpreting those results... > > And that's not even getting into the implications of scheduling across > different CPUs, CPUidle, etc. where the PMU state is completely beyond > userspace's control. In general, the plan to provide userspace with > something which might happen to just about work in a few corner cases, > but is meaningless, misleading or downright broken in all others, is to > never do so. As a result, the alternative is to use the Performance Monitoring Linux API which makes use of these registers internally (assuming the PMU of your ARM board is supported in the kernel, which is definitely not a given...). While the Linux API is obviously cross platform, it does have a significant overhead which needs to be taken into account. As a result, that mode is only weakly enabled on ARM platforms exclusively. Note on the non flexibility of the implementation: the timers (native FFmpeg vs Linux API) are selected at compilation time to prevent the need of function calls, which would result in a negative impact on the cycle counters.

| * checkasm: Issue emms after benchmarking functionsMartin Storsjö2016-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions may not clean up properly after using MMX registers. For the normal testing calls, the checkasm_checked_call functions will do the cleanup (and check that functions that should clean up do it as well), but when benchmarking functions that don't clean up, we don't currently properly clean up at all. This causes issues if a benchmarked function is followed by testing of a function that is supposed to not clobber the MMX/FPU state but doesn't touch it at all.
