linux.git/arch/riscv/kernel/cpu_ops_spinwait.c, branch v5.9 Linux kernel source tree RISC-V: Add cpu_ops and modify default booting method 2020-03-31T18:25:56+00:00 Atish Patra atish.patra@wdc.com 2020-03-18T01:11:40+00:00 2875fe0561569f82d0e63658ccf0d11ce7da8922 Currently, all non-booting harts start booting after the booting hart updates the per-hart stack pointer. This is done in a way that, it's difficult to implement any other booting method without breaking the backward compatibility. Define a cpu_ops method that allows to introduce other booting methods in future. Modify the current booting method to be compatible with cpu_ops.

Currently, all non-booting harts start booting after the booting hart
updates the per-hart stack pointer. This is done in a way that, it's
difficult to implement any other booting method without breaking the
backward compatibility.

Define a cpu_ops method that allows to introduce other booting methods
in future. Modify the current booting method to be compatible with
cpu_ops.
