7bd3a64230 CHANGELOG 2021-11-22 22:31:58 -08:00
Jonathan Campbell
e67d798c94 Fix SYSENTER/SYSEXIT by using CPU_SetCPL instead of directly modifying the CPL. SetCPL makes sure to remap the page table TLB so ring transitions work properly. The Linux kernel is able to run using SEP without crashing now 2021-11-22 22:29:29 -08:00
Jonathan Campbell
99dd32fc88 Normal core bugfix: Guest page fault exception should provide the fault address, it might help things out 2021-11-22 22:28:42 -08:00

bc73b0ff90 RDMSR/WRMSR: If emulating a Pentium II stepping 3, Windows ME feels the need at startup to check and update Intel microcode. So fake it 2021-11-22 11:26:49 -08:00

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
Jonathan Campbell
fcd6bdb1bc Implement base SYSENTER/SYSEXIT logic, though Linux is not happy yet 2021-11-22 08:10:12 -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
