2021-03-16 | kvm: prefault a floating point state before restoring it | Andrei Vagin | |
If physical pages of a memory region are not mapped yet, the kernel will trigger KVM_EXIT_MMIO and we will map physical pages in bluepillHandler(). An instruction that triggered a fault will not be re-executed, it will be emulated in the kernel, but it can't emulate complex instructions like xsave, xrstor. We can touch the memory with simple instructions to workaround this problem. | |||
