x86_64 WHPX updates: - target/i386/emulate fixes - move HVF x86_mmu code to common code - fixing debug support, which was broken since around: "gdbstub: move guest debug support check to ops" a48e7d9e52f8fe8b47f4c74f3e99d9d677b87fe5 - switch over from winhvemulation to common x86 VM exit emulation code - remove some log lines - Remove WHPX CPUID traps as they're currently quite broken
Changes added since v2: - Take target/i386/emulate patches from Bernhard Beschow https://lore.kernel.org/qemu-devel/[email protected]/ - Rework state levels to an enum - Skip some state loading on the registers save path too Changes added since v1: - move HVF x86_mmu code to common code - Use x86_mmu in WHPX MMIO exits - Remove WHPX CPUID traps as they're currently quite broken - Optimise MMIO vmexits by not restoring the full state Bernhard Beschow (3): target/i386/emulate/x86_decode: Fix compiler warning target/i386/hvf/x86_mmu: Fix compiler warning target/i386/emulate/x86_decode: Actually use stream in decode_instruction_stream() Mohamed Mediouni (11): target/i386: emulate, hvf: move x86_mmu to common code whpx: i386: re-enable guest debug support whpx: preparatory changes before switching over from winhvemulation whpx: refactor whpx_destroy_vcpu to arch-specific function whpx: move whpx_get_reg/whpx_set_reg to generic code whpx: i386: switch over from winhvemulation to target/i386/emulate whpx: i386: remove remaining winhvemulation support code whpx: i386: remove messages whpx: i386: remove CPUID trapping whpx: common, i386, arm: rework state levels whpx: i386: saving/restoring less state for WHPX_LEVEL_FAST_RUNTIME_STATE accel/whpx/whpx-accel-ops.c | 8 + accel/whpx/whpx-common.c | 68 +++-- include/system/whpx-accel-ops.h | 16 +- include/system/whpx-all.h | 11 +- include/system/whpx-common.h | 6 +- include/system/whpx-internal.h | 16 - meson.build | 3 +- target/arm/whpx/whpx-all.c | 41 +-- target/i386/cpu.h | 2 +- target/i386/emulate/meson.build | 2 + target/i386/emulate/x86_decode.c | 6 +- target/i386/{hvf => emulate}/x86_mmu.c | 20 +- target/i386/{hvf => emulate}/x86_mmu.h | 0 target/i386/hvf/hvf.c | 10 +- target/i386/hvf/meson.build | 1 - target/i386/hvf/x86.c | 2 +- target/i386/hvf/x86_task.c | 2 +- target/i386/mshv/meson.build | 4 + target/i386/whpx/whpx-all.c | 391 +++++++++---------------- 19 files changed, 253 insertions(+), 356 deletions(-) rename target/i386/{hvf => emulate}/x86_mmu.c (92%) rename target/i386/{hvf => emulate}/x86_mmu.h (100%) -- 2.50.1 (Apple Git-155)
