While booting recent Linux kernel under VTi domain with the latest
open gfw, it panics as following.
Linux kernel calls sal call of
(EFI_SAL_SET_VECTORS, EFI_SAL_SET_INIT_VECTOR) and the gfw accesses
the invalid address.
The uncached physical addresses are hard coded, but they aren't
relocated when switching to virtual address mode.
And calling xen sal hypercall looks copy and past typo.
Note: I haven't tested this patch yet.
efi-vfirmware.hg/edk2-sparse/EdkXenPkg/Dxe/XenSal/XenSal.msa
seems to need modification too, but I don't know how to generate the file.
Is there any documentation describing that?
thanks,
