csky: Fixup calltrace panic

2020-05-13T09:55:06+00:00

The implementation of show_stack will panic with wrong fp: addr = *fp++; because the fp isn't checked properly. The current implementations of show_stack, wchan and stack_trace haven't been designed properly, so just deprecate them. This patch is a reference to riscv's way, all codes are modified from arm's. The patch is passed with: - cat /proc//stack - cat /proc//wchan - echo c > /proc/sysrq-trigger Signed-off-by: Guo Ren

kconfig: make arch/*/configs/defconfig the default of KBUILD_DEFCONFIG

2019-06-09T06:08:18+00:00

Until recently, if KBUILD_DEFCONFIG was not set by the arch Makefile, the default path arch/*/defconfig was used. The last users of the default are gone by the following commits: - Commit f3e20ad67b4c ("s390: move arch/s390/defconfig to arch/s390/configs/defconfig") - Commit 986a13769c4b ("alpha: move arch/alpha/defconfig to arch/alpha/configs/defconfig") Let's set arch/*/configs/defconfig as a new default. This saves KBUILD_DEFCONFIG for some architectures. Signed-off-by: Masahiro Yamada Acked-by: Catalin Marinas

csky: Fixup vdsp&fpu issues in kernel

2019-04-22T05:44:57+00:00

This fixup is continue to commit 35ff802af1c4 (csky: fixup remove vdsp implement for kernel.) and in that patch I didn't finish the job. We must forbid gcc to generate any vdsp & fpu instructions and remove vdsp asm in memmove.S. eg: For GCC it's -mcpu=ck860 and For AS it's -Wa,-mcpu=ck860fv Signed-off-by: Guo Ren

csky: stacktrace supported.

2018-12-31T15:12:22+00:00

The gcc option "-mbacktrace" will push fp(r8),lr into stack and we could unwind the stack with: fp = *fp lr = (unsigned int *)fp[1] Signed-off-by: Guo Ren
