Do you have this in a public branch based on this tree? https://github.com/tianocore/edk2 On 2015-02-12 03:18:52, Ard Biesheuvel wrote: > This series implements support for executing Tianocore inside a Xen > guest domain on 64-bit ARM systems (AArch64) > > The first part addresses ARM platform specifics, primarily to allow a > Tianocore binary image to be runtime relocatable, and execute from DRAM. > > The second part refactors the XenBus support, and adds some missing device > drivers that are needed to execute on ARM: a Xen PV console and a real time > clock driver. > > Finally, patch #29 wraps it all together and implements the .dsc and .fdf > platform descriptions that can be used to build the binary image. > > NOTES: > - the Xen RTC driver is a dummy implementation, as it is a Runtime driver > which > is callable through Runtime Services from the OS, and this is currently not > supportable under Xen, due to the need to share the shared info page between > the OS and the firmware > - UEFI maps the entire physical memory space as cached, and relies on Xen to > use the correct stage2 mappings for regions that are backed by devices, such > as the GIC or device passthrough.
