Hi, apparently AArch32 of ARMv8 is backwards compatible to ARMv7, so we can basically run OpenBSD/armv7 on those new fancy chips.
Early on set_cpufuncs() is called and makes the kernel panic if it can't find a setup routine for the processor it is running on. This diff allows set_cpufuncs() to succeed on the newer Cortex-A53, A57 and A72. This way, and including some other (still) local diffs, I have the brand new raspberry Pi 3 in multiuser: http://ix.io/oJV Patrick diff --git sys/arch/arm/arm/cpufunc.c sys/arch/arm/arm/cpufunc.c index 4fcc88a..8c8e0cf 100644 --- sys/arch/arm/arm/cpufunc.c +++ sys/arch/arm/arm/cpufunc.c @@ -1003,7 +1003,10 @@ set_cpufuncs() (cputype & CPU_ID_CORTEX_A8_MASK) == CPU_ID_CORTEX_A8 || (cputype & CPU_ID_CORTEX_A9_MASK) == CPU_ID_CORTEX_A9 || (cputype & CPU_ID_CORTEX_A15_MASK) == CPU_ID_CORTEX_A15 || - (cputype & CPU_ID_CORTEX_A17_MASK) == CPU_ID_CORTEX_A17) { + (cputype & CPU_ID_CORTEX_A17_MASK) == CPU_ID_CORTEX_A17 || + (cputype & CPU_ID_CORTEX_A53_MASK) == CPU_ID_CORTEX_A53 || + (cputype & CPU_ID_CORTEX_A57_MASK) == CPU_ID_CORTEX_A57 || + (cputype & CPU_ID_CORTEX_A72_MASK) == CPU_ID_CORTEX_A72) { cpufuncs = armv7_cpufuncs; cpu_reset_needs_v4_MMU_disable = 1; /* V4 or higher */ arm_get_cachetype_cp15v7();
