[edk2-devel] [PATCH v5 22/35] OvmfPkg/XenPlatformPei: no hvmloader: get the E820 table via hypercall

2019-08-13 Thread Anthony PERARD
When the Xen PVH entry point has been used, hvmloader hasn't run and hasn't prepared an E820 table. The only way left to get an E820 table is to ask Xen via an hypercall. We keep the result cached to avoid making a second hypercall which would give the same result. Ref: https://bugzilla.tianocore
