linux-toradex.git/arch/csky/abiv2/memmove.S, branch master Linux kernel for Apalis and Colibri modules csky: Fixup vdsp&fpu issues in kernel 2019-04-22T05:44:57+00:00 Guo Ren ren_guo@c-sky.com 2019-02-19T04:32:41+00:00 3dfc242f11d792535db774613c6fd1df565c2137 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 <ren_guo@c-sky.com>
