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
I took Gerd's recent patch and modified it to include the access-size
property, as well as fixed problems pointed in previous reviews of
the test device itself.
I did notice 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
