2020-05-15csky: Fixup gdbmacros.txt with name sp in thread_structGuo Ren-1/+1
The gdbmacros.txt use sp in thread_struct, but csky use ksp. This cause bttnobp fail to excute. TODO: - Still couldn't display the contents of stack. Signed-off-by: Guo Ren <>
2020-05-13csky: Fixup remove unnecessary save/restore PSR codeGuo Ren-1/+0
All processes' PSR could success from SETUP_MMU, so need set it in INIT_THREAD again. And use a3 instead of r7 in __switch_to for code convention. Signed-off-by: Guo Ren <>
2020-03-08csky: Implement ftrace with regsGuo Ren-0/+1
This patch implements FTRACE_WITH_REGS for csky, which allows a traced function's arguments (and some other registers) to be captured into a struct pt_regs, allowing these to be inspected and/or modified. Signed-off-by: Guo Ren <>
2018-12-31csky: remove unused members in processor.hGuo Ren-1/+0
Cleanup struct cpuinfo_csky and struct thread_struct, remove all esp0 related code. We could get pt_regs from sp and backtrace could use fp in switch_stack. Signed-off-by: Guo Ren <>
2018-12-31csky: fixup save hi,lo,dspcr regs in switch_stack.Guo Ren-2/+0
HI, LO, DSPCR registers are 807/810 related regs and no need for 610/860. All of the regs must be saved in pt_regs and switch_stack. This patch fixup saving dspcr reg in switch_stack and pt_regs. Signed-off-by: Guo Ren <>
