e291f47383 Do not signal fault on SEP MSRs, continue debugging why Linux SYSENTER seems to jump into some arbitrary location that immediately does a WRMSR (???) 2021-11-22 08:30:43 -08:00
Jonathan Campbell
c2496f1404 SYSENTER/SYSEXIT must use continue, not break, to avoid the SAVEIP that would set the instruction pointer back to just after SYSENTER. I thought it seemed weird that Linux would execute SYSENTER just to then execute INT 80h 2021-11-22 08:22:45 -08:00

132cc18e36 Pentium II: Add SYSENTER-related MSRs, update SYSENTER validiation as documented by Intel 2021-11-22 07:47:51 -08:00
Jonathan Campbell
853611aef7 Update CPUID to always return SEP set for Pentium II, and to signal availability through the stepping number, because Intel set a feature bit not actually implemented until a later model, and OSes will not attempt SYSENTER unless stepping 3 or higher 2021-11-22 07:34:34 -08:00
