Regression Is this issue a regression: (Y/N) Y First bad commit 60943c04f3bcd0ed32a9844993d1182c917b978b  Author: Tyler Retzlaff Date:   Fri Aug 11 12:20:47 2023 -0700     eal/x86: use intrinsics for power management     Inline assembly is not supported for MSVC x64 instead use _umonitor,     _umwait and _tpause intrinsics.     Signed-off-by: Tyler Retzlaff     Acked-by: Morten Brørup     Acked-by: Konstantin Ananyev test on SPR only The bad commit 60943c04f3 will build failed, fixed commit ac1d4db91e (eal/x86: fix build on systems with WAITPKG) -- You are receiving this mail because: You are the assignee for the bug.
