These two patches introduce: 1) A ISA debugexit port device, that when written, causes qemu to exit with the exit code passed as parameter. 2) A port of the existing testdev present on qemu-kvm to qemu
One particular comment of previous reviews wasn't addressed, but I'd like people to see this to see if we're in the right direction. Another thing I did notice is that with the new test device, a lot of the kvm-unit-tests are failing. The same tests are passing fine under qemu-kvm, meaning there are some bugs we need to address. Example: qemu-kvm: $ x86_64-softmmu/qemu-system-x86_64 -device testdev -serial stdio -kernel /path/to/kvm/unittests/pcid.flat VNC server running on `127.0.0.1:5900' enabling apic CPUID consistency: PASS Test on PCID when disabled: PASS Test on INVPCID when disabled: PASS 3 tests, 0 failures $ echo $? 0 qemu: $ x86_64-softmmu/qemu-system-x86_64 -device pc-testdev -serial stdio -device isa-debugexit,iobase=0xf4,access-size=4 -kernel /path/to/kvm/unittests/pcid.flat VNC server running on `127.0.0.1:5900' enabling apic CPUID consistency: PASS Test on PCID when disabled: FAIL Test on INVPCID when disabled: PASS 3 tests, 1 failures $ echo $? 3 Hervé Poussineau (1): debugexit: support for custom exit port (LGPL VGA BIOS port 0x501) Lucas Meneghel Rodrigues (1): hw: Add test device for unittests execution v2 hw/debugexit.c | 68 +++++++++++++++++++++ hw/i386/Makefile.objs | 3 +- hw/pc-testdev.c | 160 ++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 230 insertions(+), 1 deletion(-) create mode 100644 hw/debugexit.c create mode 100644 hw/pc-testdev.c -- 1.7.11.4
