crypto: powerpc - convert to use crypto_simd_usable()

2019-04-18T14:15:04Z

Replace all calls to in_interrupt() in the PowerPC crypto code with !crypto_simd_usable(). This causes the crypto self-tests to test the no-SIMD code paths when CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y. The p8_ghash algorithm is currently failing and needs to be fixed, as it produces the wrong digest when no-SIMD updates are mixed with SIMD ones.

locking/rwsem: Remove arch specific rwsem files

2019-04-03T12:50:50Z

As the generic rwsem-xadd code is using the appropriate acquire and release versions of the atomic operations, the arch specific rwsem.h files will not be that much faster than the generic code as long as the atomic functions are properly implemented. So we can remove those arch specific rwsem.h and stop building asm/rwsem.h to reduce maintenance effort. Currently, only x86, alpha and ia64 have implemented architecture specific fast paths. I don't have access to alpha and ia64 systems for testing, but they are legacy systems that are not likely to be updated to the latest kernel anyway. By using a rwsem microbenchmark, the total locking rates on a 4-socket 56-core 112-thread x86-64 system before and after the patch were as follows (mixed means equal # of read and write locks): Before Patch After Patch # of Threads wlock rlock mixed wlock rlock mixed ------------ ----- ----- ----- ----- ----- ----- 1 29,201 30,143 29,458 28,615 30,172 29,201 2 6,807 13,299 1,171 7,725 15,025 1,804 4 6,504 12,755 1,520 7,127 14,286 1,345 8 6,762 13,412 764 6,826 13,652 726 16 6,693 15,408 662 6,599 15,938 626 32 6,145 15,286 496 5,549 15,487 511 64 5,812 15,495 60 5,858 15,572 60 There were some run-to-run variations for the multi-thread tests. For x86-64, using the generic C code fast path seems to be a little bit faster than the assembly version with low lock contention. Looking at the assembly version of the fast paths, there are assembly to/from C code wrappers that save and restore all the callee-clobbered registers (7 registers on x86-64). The assembly generated from the generic C code doesn't need to do that. That may explain the slight performance gain here. The generic asm rwsem.h can also be merged into kernel/locking/rwsem.h with no code change as no other code other than those under kernel/locking needs to access the internal rwsem macros and functions.

kbuild: warn redundant generic-y

2019-03-17T03:56:31Z

The generic-y is redundant under the following condition: - arch has its own implementation - the same header is added to generated-y - the same header is added to mandatory-y If a redundant generic-y is found, the warning like follows is displayed: scripts/Makefile.asm-generic:20: redundant generic-y found in arch/arm/include/asm/Kbuild: timex.h I fixed up arch Kbuild files found by this.

powerpc: generate uapi header and system call table files

2018-12-21T03:46:50Z

System call table generation script must be run to gener- ate unistd_32/64.h and syscall_table_32/64/c32/spu.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32/64.h and syscall_table- _32/64/c32/spu.h files by the syscall table generation script invoked by parisc/Makefile and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/systbl.S file.

powerpc: allow compiling with GENERIC_MSI_IRQ_DOMAIN

2017-07-24T11:19:32Z

This allows building powerpc with the GENERIC_MSI_IRQ_DOMAIN Kconfig by enabling the asm-generic msi.h in Kbuild. Without this, there's a compilation error [1] because powerpc, as most arches, doesn't provide an asm/msi.h.

word-at-a-time.h: fix some Kbuild files

2015-10-06T18:52:48Z

arch/tile added word-at-a-time.h after the patch that added generic-y entries; the generic-y entry is now stale. arch/h8300 is newer than the generic-y patch for word-at-a-time.h, and needs a generic-y entry. arch/powerpc seems to have gotten a generic-y entry by mistake in the first patch; this change removes it.
