[Qemu-devel] [PATCH v2 0/2] x86/cpu: Enable direct stores cpu features

Posted by Liu Jingqi 7 years ago

Enable direct stores cpu features including MOVDIRI and MOVDIR64B.

MOVDIRI moves doubleword or quadword from register to memory through
direct store.
MOVDIR64B moves 64-bytes as direct-store with 64-bytes write atomicity.

Changelog:
v2:
	Separated from the series http://lists.nongnu.org/archive/html/qemu-devel/2018-07/msg02330.html
	since umonitor/umwait/tpause cpu features are not ready yet.
v1:
	Sent out with umonitor/umwait/tpause cpu features.
