Alex,
A very long time ago QEMU supported disabling the translation cache via “-translation
no-cache”. That option was deliberately removed. We are looking into a hexagon-specific
failure when there’s a TB lookup miss from a cpu_loop_exit_restore(). I’d like to test
our fix for this failure and was wondering if there’s any mechanism to disable the cache.
There’s a “-accel tcg,tb-size=0” – but this won’t accomplish what I’m looking to do – will
it? If not, is there another way to disable the cache?
There is no way to disable the cache, only to make it small so that it
overflows often.
