Raw Normal View History

Bring in the start of the arm64 kernel. This is only the minimum set of files needed to boot in qemu. As such it is missing a few things. The bus_dma code is currently only stub functions with a full implementation from the development tree to follow. The gic driver has been copied as the interrupt framework is different. It is expected the two drivers will be merged by the arm intrng project, however this will need to be imported into the tree and support for arm64 would need to be added. This includes code developed by myself, SemiHalf, Ed Maste, and Robin Randhawa from ARM. This has been funded by the FreeBSD Foundation, with early development by myself in my spare time with assistance from Robin.

ARM64 opt_global.h
Add support for intrng to arm64. As the GICv3 drivers will need to be updated, and until further testing can be done, this is disabled for now. It is expected arm64 will switch to this interface, and the old interface will be removed before 11.0 is released. Obtained from: ABT Systems Ltd Relnotes: yes Sponsored by: The FreeBSD Foundation

Add support for booting kernel directly from U-Boot using booti command. In some cases, like is locked bootstrap or device's inability to boot from removable media, we cannot use standard boot sequence and is necessary to boot kernel directly from U-Boot.

LINUX_BOOT_ABI opt_global.h
Dynamically select LSE-based atomic(9)s on arm64. Once all CPUs are online, determine if they all support LSE atomics and set lse_supported to indicate this. For now the atomic(9) implementations are still always inlined, though it would be preferable to create out-of-line functions to avoid text bloat. This was not done here since big.little systems exist in which some CPUs implement LSE while others do not, and ifunc resolution must occur well before this scenario can be detected. It does seem unlikely that FreeBSD will ever run on such platforms, however, so converting atomic(9) to use ifuncs is probably a good next step. Add a LSE_ATOMICS arm64 kernel configuration option to unconditionally select LSE-based atomic(9) implementations when the target system is known.

Add rudimentary support for building FreeBSD/arm64 with COMPAT_FREEBSD32. Right now I'm using two Raspberry Pi's (2 and 3) to test CloudABI support for armv6, armv7 and aarch64. It would be nice if I could restrict this to just a single instance when testing smaller changes. This is why I'd like to get COMPAT_CLOUDABI32 to work on arm64. As COMPAT_CLOUDABI32 depends on COMPAT_FREEBSD32, at least for the ELF loading, this change adds all of the bits necessary to at least build a kernel with COMPAT_FREEBSD32. All of the machine dependent system calls are still stubbed out, for the reason that implementations for these are only useful if actual support for running FreeBSD binaries is added. This is outside the scope of this work. Reviewed by: andrew Differential Revision: https://reviews.freebsd.org/D13144

# Binary compatibility
Move most of the contents of opt_compat.h to opt_global.h. opt_compat.h is mentioned in nearly 180 files. In-progress network driver compabibility improvements may add over 100 more so this is closer to "just about everywhere" than "only some files" per the guidance in sys/conf/options. Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h is created on all architectures. Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the set of compiled files.

Support the EFI Runtime Services on arm64. As with amd64 we use the 1:1 mapping. This uses the new common code shared with amd64. The RTC should only be accessed via EFI. There is no locking around it as the spec only has this as a requirement for the PC-AT CMOS device.
