2022-03-04OvmfPkg: Make the Xen ELF header generator more flexibleSebastien Boeuf1-32/+109
Adding some flexibility to the program through optional parameters and global define, so that other targets can use the generator. * A global define is added so that we can choose at build time if we want to use 32-bit or 64-bit base structures. * A first optional parameter is added so the user can provide the expected blob size of the generated binary. * A second optional parameter is added so the user can specify an output file to which the generated output will be printed. The default behavior isn't modified. Acked-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com> Reviewed-by: Jiewen Yao <jiewen.yao@intel.com>

2019-08-21OvmfPkg/OvmfXen: Creating an ELF headerAnthony PERARD1-0/+140
This patch changes the flash device image of OvmfXen to make it look like it's an ELF. For this, we replace the empty embedded variable store by a binary array, which is a ELF file header. The ELF header explain to a loader to load the binary at the address 1MB, then jump to the PVH entry point which will be created in a later patch. The header also includes a Xen ELF note that is part of the PVH ABI. That patch include OvmfXenElfHeaderGenerator.c which can be use to regenerate the ELF header, but this will be a manual step.
