2012-12-13lib/raid6: Add AVX2 optimized recovery functionsJim Kukunas1-0/+3
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.

2012-05-22lib/raid6: cleanup gen_syndrome function selectionJim Kukunas1-47/+57
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 <[email protected]> Signed-off-by: NeilBrown <[email protected]>

2012-05-22lib/raid6: fix test program buildJim Kukunas1-1/+1
<linux/module.h> drags in headers which are not visible to userspace, thus breaking the build for the test program. Signed-off-by: Jim Kukunas <[email protected]> Signed-off-by: NeilBrown <[email protected]>
2011-10-31md: Add module.h to all files using it implicitlyPaul Gortmaker1-0/+1
A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in md dir are actually calling out for <module.h> explicitly in advance. Signed-off-by: Paul Gortmaker <[email protected]>

Rename raid6/raid6x86.h to raid6/x86.h and modify some comments. Signed-off-by: NeilBrown <[email protected]>
2010-08-12Make lib/raid6/test build correctly.NeilBrown1-1/+1
Some bit-rot needs to be cleaned out. Signed-off-by: NeilBrown <[email protected]>
2010-08-11Rename raid6 files now they're in a 'raid6' directory.David Woodhouse1-0/+154
