lib/raid6: build proper files on corresponding arch

2012-12-13T08:51:04Z

sse and avx2 stuff only exist on x86 arch, and we don't need to build altivec on x86. And we can do that at lib/raid6/Makefile. Proposed-by: H. Peter Anvin Signed-off-by: Yuanhan Liu Reviewed-by: H. Peter Anvin Signed-off-by: Jim Kukunas Signed-off-by: NeilBrown

lib/raid6: Add AVX2 optimized gen_syndrome functions

2012-12-13T08:51:03Z

Add AVX2 optimized gen_syndrom functions, which is simply based on sse2.c written by hpa. Signed-off-by: Yuanhan Liu Reviewed-by: H. Peter Anvin Signed-off-by: Jim Kukunas Signed-off-by: NeilBrown

lib/raid6: Add AVX2 optimized recovery functions

2012-12-13T05:42:01Z

Optimize RAID6 recovery functions to take advantage of the 256-bit YMM integer instructions introduced in AVX2. The patch was tested and benchmarked before submission. However hardware is not yet released so benchmark numbers cannot be reported. Acked-by: "H. Peter Anvin" Signed-off-by: Jim Kukunas Signed-off-by: NeilBrown

lib/raid6: fix sparse warnings in recovery functions

2012-05-28T04:10:22Z

Make the recovery functions static to fix the following sparse warnings: lib/raid6/recov.c:25:6: warning: symbol 'raid6_2data_recov_intx1' was not declared. Should it be static? lib/raid6/recov.c:69:6: warning: symbol 'raid6_datap_recov_intx1' was not declared. Should it be static? lib/raid6/recov_ssse3.c:22:6: warning: symbol 'raid6_2data_recov_ssse3' was not declared. Should it be static? lib/raid6/recov_ssse3.c:197:6: warning: symbol 'raid6_datap_recov_ssse3' was not declared. Should it be static?

lib/raid6: cleanup gen_syndrome function selection

2012-05-22T03:54:24Z

Reorders functions in raid6_algos as well as the preference check to reduce the number of functions tested on initialization. Also, creates symmetry between choosing the gen_syndrome functions and choosing the recovery functions. Signed-off-by: Jim Kukunas Signed-off-by: NeilBrown
