This patch series enable Unikraft on arm64/kvm. As we haven't implemented GIC libraries and full timer support, this patch series can ONLY work without uksched. v1: https://lists.xenproject.org/archives/html/minios-devel/2018-03/msg00040.html v2: https://lists.xenproject.org/archives/html/minios-devel/2018-04/msg00145.html v3: https://github.com/Weichen81/unikraft for OSS demo v4: https://lists.xenproject.org/archives/html/minios-devel/2018-07/msg00014.html v5: https://lists.xenproject.org/archives/html/minios-devel/2018-08/msg00044.html v5 -> v6 Changes: 1. Base on latest upstream, 2. Fix some typos, 3. Fix copyright of atomic.h as discussed in ML, 4. Move mm.h from plat/common to plat/kvm, 5. Add comment in Arm64 link script source about adding boot stack and plage-table in BSS section, 6. Move plat/common/asm.h to include/uk/asm.h, 7. Remove dependence of LIBUKDEBUG_PRINTD from KVM_KERNEL_SERIAL_CONSOLE and KVM_KERNEL_VGA_CONSOLE, 8. Rename KVM_EARLY_DEBUG_PL011_UART to EARLY_PRINT_CONSOLE_PL011_UART_ADDR and move it from plat/kvm to plat/ for other platforms 9. Rename arm/console.c to arm/pl011.c, 10. Introduce an extra variable to check whether PL011 has been initialized, 11. Use VA/PA cache maintenance instead of set/way instructions, 12. Add a short TODO comment and explain that we are using non-floating point for now, 13. Move time.c and tscclock.c to x86 folder and implement similar files for Arm, 14. Implement ukplat_time_* APIs in Arm/time.c, 15. Use uint32_t for get_counter_frequency, 16. Correct counter_mult in time.c comment to ns_per_tick, 17. Enable ARM64_ERRATUM_858921 for Arm64 by default, 18. Use DLVL_CRIT instead of DLVL_ERR in traps' messages, 19. Use ukplat_crash() instead of UK_CRASH() in traps' messages, 20. Rename TRAP_STACK_SIZE to __TRAP_STACK_SIZE, 21. Replace SMP to UKPLAT_LCPU_MULTICORE, 22. Add source code files of FreeBSD that we referred to copyright header, 23. Use ALIGN_DOWN replace ALIGN_UP to caculate new stack top, 24. Warning when find an invalid PSCI method, 25. Remove UK_BUG from reset function, 26. Halt the system if we don't have PSCI method to reset/shutdown system, 27. Implement system_off for x86 to make shutdown.c architecture independent, 28. Get arch_timer clock frequency from device tree. 29. Fix errno.h missing for nolibc/time.c, 30. Add function for stack pointer retrieval, 31. Add some comments.
