Add the code at tools/tests/vhpet. See comment in tools/tests/vhpet/main.c for details on running either in a xen source tree or elsewhere. A basic in source tree usage is: make -C tools/tests/vhpet run Does repro the bug: ..MP-BIOS bug: 8254 timer not connected to IO-APIC The make file includes coping hpet.c and hpet.h from the source tree. hpet.c is then modifed to remove all include file and add the emul.h include file. The manual test code has only a few automatic checks that output messages to stderr: 1) Possible ..MP-BIOS bug: 8254 timer... if 1st period is not <= the expected value 2) hpet_set_mode(%ld): T%d Error: Set ... if read of comparator != write of comparator in 3) hpet_check_stopped(%ld): T%d Error: Set ... if read != write 4) main(%ld): With clock stopped mc64 changed: ... if hpet_save returns different master clock values when called more then once. It also generates a lot of output, which is why the sugested way to use includes a redirect of stdout to a file. Signed-off-by: Don Slutz <dslutz@verizon.com> Acked-by: Tim Deegan <tim@xen.org>
