riscv: abstract out CSR names for supervisor vs machine mode

2019-11-05T17:20:42Z

Many of the privileged CSRs exist in a supervisor and machine version that are used very similarly. Provide versions of the CSR names and fields that map to either the S-mode or M-mode variant depending on a new CONFIG_RISCV_M_MODE kconfig symbol. Contains contributions from Damien Le Moal and Paul Walmsley .

riscv: simplify the stack pointer setup in head.S

2019-04-25T21:51:10Z

We don't need THREAD_SIZE in asm-offsets.c as we can just calculate the value of init_thread_union + THREAD_SIZE using cpp, just like we do a few lines above. Signed-off-by: Christoph Hellwig Reviewed-by: Atish Patra Signed-off-by: Palmer Dabbelt

RISC-V: Add _TIF_NEED_RESCHED check for kernel thread when CONFIG_PREEMPT=y

2019-01-23T20:56:19Z

The cond_resched() can be used to yield the CPU resource if CONFIG_PREEMPT is not defined. Otherwise, cond_resched() is a dummy function. In order to avoid kernel thread occupying entire CPU, when CONFIG_PREEMPT=y, the kernel thread needs to follow the rescheduling mechanism like a user thread.
