[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] XSAVE flavors
Shuai, originally I only meant to inquire about the state of the promised alternatives improvement to the XSAVE code. However, while looking over the code in question again I stumbled across a separate issue: XSAVES, just like XSAVEOPT, may use the "modified" optimization. However, the fcs and fds handling code that has been present around the use of XSAVEOPT did not also get applied to the XSAVES path. I suppose this was just an oversight? With this another question then is whether, when both XSAVEC and XSAVEOPT are available, it is indeed always better to use XSAVEC (as the code is doing after your enabling).
