Does invlpg do anything in qemu or is it bascially a nop?

"Learning opportunity spoilt"
Yes, but it's not immediately obvious whether this particular instruction is working correctly. I assume that the OP has a problem with it in qemu and will now come back with the real question.

It would be a bit pointless if it did nothing, wouldn't it?OSwhatever wrote:Does invlpg do anything in qemu or is it bascially a nop?

Hi,
If a CPU has "0 TLB entries", then what should INVLPG do?
Cheers,

For Qemu, how many entries does CPUID say the TLB holds?iansjack wrote:It would be a bit pointless if it did nothing, wouldn't it?OSwhatever wrote:Does invlpg do anything in qemu or is it bascially a nop?
