ossl: Add GCM support on powerpc64/powerpc64le (POWER8+)Separate ossl's existing AES-NI GCM implementation into a commonossl_aes_gcm.c and add conditionals to switch between OpenSSL's AES-NIand POWER8 GCM routines depending on the architecture. Since theexisting AVX-512 implementation is less agnostic, move it into aseparate ossl_aes_gcm_avx512.c.Reviewed by: markjMFC after: 1 monthDifferential Revision: https://reviews.freebsd.org/D44274 List of files: /src/sys/conf/files.powerpc

ddf0ed09bd8f83677407db36828aca2c10f419c9 - sdt: Implement SDT probes using hot-patching

Wed, 19 Jun 2024 20:57:09 +0000

sdt: Implement SDT probes using hot-patchingThe idea here is to avoid a memory access and conditional branch perprobe site. Instead, the probe is represented by an "unreachable"unconditional function call. asm goto is used to store the address ofthe probe site (represented by a no-op sled) and the address of thefunction call into a tracepoint record. Each SDT probe carries a listof tracepoints.When the probe is enabled, the no-op sled corresponding to eachtracepoint is overwritten with a jmp to the corresponding label. Theimplementation uses smp_rendezvous() to park all other CPUs while theinstruction is being overwritten, as this can't be done atomically ingeneral. The compiler moves argument marshalling code and thesdt_probe() function call out-of-line, i.e., to the end of the function.Per gallatin@ in D43504, this approach has less overhead when probes aredisabled. To make the implementation a bit simpler, I removed supportfor probes with 7 arguments; nothing makes use of this except aregression test case. It could be re-added later if need be.The approach taken in this patch enables some more improvements:1. We can now automatically fill out the "function" field of SDT probe names. The SDT macros let the programmer specify the function and module names, but this is really a bug and shouldn't have been allowed. The intent was to be able to have the same probe in multiple functions and to let the user restrict which probes actually get enabled by specifying a function name or glob.2. We can avoid branching on SDT_PROBES_ENABLED() by adding the ability to include blocks of code in the out-of-line path. For example: if (SDT_PROBES_ENABLED()) { int reason = CLD_EXITED; if (WCOREDUMP(signo)) reason = CLD_DUMPED; else if (WIFSIGNALED(signo)) reason = CLD_KILLED; SDT_PROBE1(proc, , , exit, reason); }could be written SDT_PROBE1_EXT(proc, , , exit, reason, int reason; reason = CLD_EXITED; if (WCOREDUMP(signo)) reason = CLD_DUMPED; else if (WIFSIGNALED(signo)) reason = CLD_KILLED; );In the future I would like to use this mechanism more generally, e.g.,to remove branches and marshalling code used by hwpmc, and generally tomake it easier to add new tracepoint consumers without having to addmore conditional branches to hot code paths.Reviewed by: Domagoj Stolfa, avgMFC after: 2 monthsDifferential Revision: https://reviews.freebsd.org/D44483 List of files: /src/sys/conf/files.powerpc

a89262079edba80ba6133e81af1e14ab7386f53a - Consistently provide ffs/fls using builtins

Thu, 06 Jul 2023 17:45:39 +0000

Consistently provide ffs/fls using builtinsUse of compiler builtin ffs/ctz functions will result in optimizedinstruction sequences when possible, and fall back to calling a functionprovided by the compiler run-time library. We have slowly shifted ourplatforms to take advantage of these builtins in 60645781d613 (arm64),1c76d3a9fbef (arm), 9e319462a03a (powerpc, partial).Some platforms still rely on the libkern implementations of thesefunctions provided by libkern, namely riscv, powerpc (ffs*, flsll), andi386 (ffsll and flsll). These routines are slow, as they perform alinear search for the bit in question. Even on platforms lackingdedicated bit-search instructions, such as riscv, the compiler librarywill provide better-optimized routines, e.g. by using binary search.Consolidate all definitions of these functions (whether currently usingbuiltins or not) to libkern.h. This should result in equivalent orbetter performing routines in all cases.One wart in all of this is the existing HAVE_INLINE_F*** macros, whichwe use in a few places to conditionally avoid the slow libkern routines.These aren't easily removed in one commit. For now, provide thesedefines unconditionally, but marked for removal after subsequentcleanup.Removal of the now unused libkern routines will follow in the nextcommit.Reviewed by: dougm, imp (previous version)Sponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D40698 List of files: /src/sys/conf/files.powerpc
