Hi Laszlo,
I find the latest Ovmf doesn't work on Xen. The related change is:
http://sourceforge.net/mailarchive/message.php?msg_id=29615810
The issue may be the following code in OvmfPkg/PlatformPei/Platform.c
+ AddIoMemoryRangeHob (TopOfMemory < BASE_2GB ? BASE_2GB : TopOfMemory,
0xFEC00000);
+ AddIoMemoryBaseSizeHob (0xFEC00000, SIZE_4KB);
+ AddIoMemoryBaseSizeHob (0xFED00000, SIZE_1KB);
+ AddIoMemoryBaseSizeHob (PcdGet32(PcdCpuLocalApicBaseAddress), SIZE_1MB);
If change the
AddIoMemoryRangeHob (TopOfMemory < BASE_2GB ? BASE_2GB : TopOfMemory,
0xFEC00000);
to
AddIoMemoryRangeHob (TopOfMemory < BASE_2GB ? BASE_2GB : TopOfMemory,
0xFEC00000 - TopOfMemory);
it works.
Thanks,
Bei
