Sure, I will make the necessary changes in VirtioMmioDeviceLib and try do the build test but I don't have aarch64 platform to verify at the runtime.Actually, dependent on your GNU/Linux distribution, it is pretty easy to do on x86_64 too. It comes together from two parts: (1) installing an aarch64 cross compiler (2) installing qemu-system-aarch64 (from source or distro package), and then either using it directly (from the cmdline) or with the libvirt toolstack The only "real" difference is that it's going to use TCG and not KVM (software emulation rather than hardware virtualization), so it will be slower, but that's not really a problem if you only care about your VM until the firmware boots the OS :) On Fedora, the cross-compiler (and cross-binutils) packages are built from the following SRPMs: https://koji.fedoraproject.org/koji/buildinfo?buildID=921790 https://koji.fedoraproject.org/koji/buildinfo?buildID=912429 ("cross-gcc", "cross-binutils") Linaro distributes distro-independent cross compilers: http://www.linaro.org/downloads/ Build instructions for ArmVirtQemu, and usage hints for the QEMU command line, can be found in the Linaro Wiki: https://wiki.linaro.org/LEG/UEFIforQEMU
v2 is almost ready for review, I have made all the necessary changes in VirtioMmioDeviceLib and it builds fine for aarch64 but I am having trouble booting the qemu-aarch64 in general. On serial console I see the UEFI debug messages but it never reaches to UEFI shell. I have been following the steps from https://wiki.linaro.org/LEG/UEFIforQEMU qemu-system-aarch64 \ -m 1024 \ -cpu cortex-a57 \ -M virt \ -bios QEMU_EFI.fd \ -serial stdio I tried this steps with and without my patches and it resulted in the same. It seems like I am missing something in the qemu cli, do I need to pass special dtb file or something similar ? P.S: the wiki talks about a prebuilt qcow2 image but the link is dead, instead I downloaded a qcow2 file from Ubuntu repo. -Brijesh _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel
