Hi all,
here's v2, dropping patch 3 and incorporating hopefully all of Radim's feedback.
Thx.
v1 cover letter:
there's this mce-inject.ko module in the kernel which allows for injecting real MCEs and thus test the MCE handling code.
It is doubly useful to be able to inject same MCEs in a guest so that testing of the MCE handling code can happen even easier/faster. In order to be able to do that on an AMD guest, we need to emulate some bits and pieces like the HWCR[McStatusWrEn] bit which allows writes to the MCi_STATUS registers without a #GP.
The below does that and with it I'm able to properly inject MCEs in said guest.
