AVX not passed through to VM

[mvdk]

When using 4.2.6, AVX is not passed through to the VM.

Probably necessary to save/restore YMM registers on the way through.

Any plans for including this?

See 5.0 Beta.

Replying to frank:

See 5.0 Beta.

I believe I already did, but please correct me if it is included in 5.0 Beta. As far as I can see, there is no mentioning of AVX in the 5.0 Beta release notes and when running 5.0 Beta 2, I also don't see the avx extension being available under a guest Linux when executing "cat /proc/cpuinfo" on a computer with AVX support in the CPU. If I try and compile a program using AVX instructions under the guest Linux, it also gives an illegal instruction error when executed.

Sorry, actually you are right. 5.0 Beta 3 (expected very soon) will contain the last fixes and enables the new code. This wasn't done in Beta 1 and Beta 2 yet.

[frank]

Beta 3 now available, feedback welcome. But AVX is currently only enabled for Intel CPUs. The next release will also enable it for AMD CPUs.

Beta 3 looks good to me...thanks for the effort.
