When I do "grep parity -r linux", I found many parity calculations
distributed in many drivers.
This patch series does:
1. provide generic and architecture-specific parity calculations
2. remove drivers' local parity calculations, use bitops' parity
functions instead
3. replace "hweightN(x) & 1" with "parityN(x)" to improve readability,
and improve performance on some CPUs that without popcount support
I did not use GCC's __builtin_parity* functions, based on the following reasons:
1. I don't know where to identify which version of GCC from the beginning
supported __builtin_parity for the architecture.
2. For the architecture that doesn't has popcount instruction, GCC instead use
"call __paritysi2" (__paritydi2 for 64-bits). So if use __builtin_parity, we must
provide __paritysi2 and __paritydi2 functions for these architectures.
Additionally, parity4,8,16 might be "__builtin_parity(x & mask)", but the "& mask"
operation is totally unnecessary.
3. For the architecture that has popcount instruction, we do the same things.
4. For powerpc, sparc, and x86, we do runtime patching to use popcount instruction
if the CPU support.
I have compiled successfully with x86_64_defconfig, i386_defconfig, pseries_defconfig
and sparc64_defconfig.
Changes to v2:
- Add constant PARITY_MAGIC (proposals by Sam Ravnborg)
- Add include/asm-generic/bitops/popc-parity.h (proposals by Chris Metcalf)
- Tile uses popc-parity.h directly
- Mips uses popc-parity.h if has usable __builtin_popcount
- Add few comments in powerpc's and sparc's parity.S
- X86, remove custom calling convention
Changes to v1:
- Add runtime patching for powerpc, sparc, and x86
- Avr32 use grenric parity too
- Fix error in ssfdc's patch, and add commit message
- Don't change the original code composition of drivers/iio/gyro/adxrs450.c
- Directly assignement to phy_cap.parity in drivers/scsi/isci/phy.c
Regards,
=== diffstat ===

When I do "grep parity -r linux", I found many parity calculations
distributed in many drivers.
This patch series does:
1. provide generic and architecture-specific parity calculations
2. remove drivers' local parity calculations, use bitops' parity
functions instead
3. replace "hweightN(x) & 1" with "parityN(x)" to improve readability,
and improve performance on some CPUs that without popcount support
I did not use GCC's __builtin_parity* functions, based on the following reasons:
1. I don't know where to identify which version of GCC from the beginning
supported __builtin_parity for the architecture.
2. For the architecture that doesn't has popcount instruction, GCC instead use
"call __paritysi2" (__paritydi2 for 64-bits). So if use __builtin_parity, we must
provide __paritysi2 and __paritydi2 functions for these architectures.
Additionally, parity4,8,16 might be "__builtin_parity(x & mask)", but the "& mask"
operation is totally unnecessary.
3. For the architecture that has popcount instruction, we do the same things.
4. For powerpc, sparc, and x86, we do runtime patching to use popcount instruction
if the CPU support.
I have compiled successfully with x86_64_defconfig, i386_defconfig, pseries_defconfig
and sparc64_defconfig.
Changes to v2:
- Add constant PARITY_MAGIC (proposals by Sam Ravnborg)
- Add include/asm-generic/bitops/popc-parity.h (proposals by Chris Metcalf)
- Tile uses popc-parity.h directly
- Mips uses popc-parity.h if has usable __builtin_popcount
- Add few comments in powerpc's and sparc's parity.S
- X86, remove custom calling convention
Changes to v1:
- Add runtime patching for powerpc, sparc, and x86
- Avr32 use grenric parity too
- Fix error in ssfdc's patch, and add commit message
- Don't change the original code composition of drivers/iio/gyro/adxrs450.c
- Directly assignement to phy_cap.parity in drivers/scsi/isci/phy.c
