From d592abd8ccc4026c51e196777031eb65c4acc4de Mon Sep 17 00:00:00 2001 From: Kimplul Date: Sun, 7 Jul 2024 14:34:39 +0300 Subject: misc fixes + Align kernel to 2MiB boundary in u-boot + Optimize alignment functions a little bit, should still have to check on real hardware but 'feels' more clean + Add early boot debugging + Put extra cores we aren't ready to account for to sleep if/when they boot. + Make BASE_PAGE_SIZE constant on riscv64/32, helps the compiler with some alignment checks among other things. --- arch/riscv64/kernel/arch.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'arch/riscv64/kernel/arch.c') diff --git a/arch/riscv64/kernel/arch.c b/arch/riscv64/kernel/arch.c index ec4cf43..4561d8b 100644 --- a/arch/riscv64/kernel/arch.c +++ b/arch/riscv64/kernel/arch.c @@ -8,6 +8,8 @@ #include #include +#include +#include #include "csr.h" #include "arch.h" @@ -19,8 +21,11 @@ id_t hartid_to_cpuid(id_t hart) if (cpuid_to_hartid(i) == hart) return i; + /* put extra cores to sleep so they don't do anything bad */ error("failed to match hart id %ld to cpu id\n", (long)hart); - /* default to zero, though this should maybe be a panic? */ + bkl_unlock(); + sleep(); + /* should never really be reached but eh */ return 0; } -- cgit v1.3
