The work is based on Chen Baozi and Volodymyr's patches. I tested this patch set with my Softiron board. This patch set is based on the latest mini-os code: (git tree: https://github.com/lorc/mini-os.git The top is " 0b4b789 Update Xen header files again") After this patch set: 1.) The scheduler for arm64 works fine. 2.) The gic/timer for arm64 works fine. I tested this patch set on Softiron(arm64) and x86_64 platform. Please see the log after the patch set: --------------------------------------------------------- (d1) - Mini-OS booting - (d1) - Setup CPU - (d1) - Setup booting pagetable - (d1) - MMU on - (d1) - Setup stack - (d1) - Jumping to C entry - (d1) Virtual -> physical offset = ffffffbfc0000000 (d1) Checking DTB at 0xffffffc008000000...
