# For VDSO32 on PPC64, we create a fake 32 bits config, on the same # principle as MIPS architecture, in order to get the correct parts of # the different asm header files. # # With the C VDSO, the performance is slightly lower, but it is worth # it as it will ease maintenance and evolution, and also brings clocks # that are not supported with the ASM VDSO. # # On an 8xx at 132 MHz, vdsotest with the ASM VDSO: # gettimeofday: vdso: 828 nsec/call #

# Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # --- # v7: # - Split out preparatory changes in a new preceding patch # - Added -fasynchronous-unwind-tables to CC flags. # # v6: # - Added missing prototypes in asm/vdso/gettimeofday.h for __c_kernel_ functions. # - Using STACK_FRAME_OVERHEAD instead of INT_FRAME_SIZE # - Rebased on powerpc/merge as of 7 Apr 2020 # - Fixed build failure with gcc 9 # - Added a patch to create asm/vdso/processor.h and more cpu_relax() in it #
