fd8d34ce272ba40f3e0218198ba542a29c390a4a - dpaa: Migrate from NCSW base to a home-grown driver

Fri, 24 Apr 2026 05:38:19 +0200

dpaa: Migrate from NCSW base to a home-grown driverThe NCSW reference base requires tuning for each target, and currentlyis configured for FMANv2. This doesn't readily work on FMANv3 devices,such as the T-series powerpc, or the LS1043 ARM. Since Freescale/NXPabandoned the NCSW driver a decade ago, it makes sense to abandon itourselves as well. This new driver uses a combination of the NCSWdriver and the Linux driver (BSD/GPL dual licensed) as a reference, butcontains no actual code from them.The DPAA (Data Path Acceleration Architecture) subsystem consists of thefollowing components:* BMan -- Buffer Manager. Manages buffer pools of different sizes (one size per pool, up to 64 pools)* QMan -- Queue Manager. Manages the interfaces between DPAA-based components and the CPU(s).* FMan -- Frame Manager. Responsible for all ethernet-related processing. Consists itself of the following components: * Ports -- interfaces to the QMan. An ethernet interface consists of 2 ports. Ports use "Next-invoked action" (NIA) descriptors to form a pipeline for processing on receive and transmit. * Parser -- performs protocol header parsing and validation. Both hardware and software parsers are available. * KeyGen -- Key generator, used to start the classification process (for the Policer), generating FQIDs and other keys based on the frame input. * Policer -- performs traffic shaping and classification* MAC -- SoC specific ethernet MAC (dTSEC, TGEC, mEMAC). Currently supports dTSEC and mEMAC, along with their MDIO blocks.Additional components not yet handled:SEC -- Security engine (crypto)RE -- RAID engineRapidIODCE -- Decompression/Compression engine, supports ZLIB, DEFLATE, andGZIP, as well as base64 encoding and decoding.BMan and QMan are accessed via cache-coherent portals, using ringbuffers as I/O. The intent is for portals to be per-CPU (core/thread)to reduce locking contention and improve performance. This driver pinsinterrupt handlers to the CPU "owning" a given portal, and uses criticalsections to prevent switching while accessing the portal. List of files: /freebsd/sys/conf/files.powerpc

ddf0ed09bd8f83677407db36828aca2c10f419c9 - sdt: Implement SDT probes using hot-patching

Wed, 19 Jun 2024 22:57:09 +0200

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: /freebsd/sys/conf/files.powerpc

a89262079edba80ba6133e81af1e14ab7386f53a - Consistently provide ffs/fls using builtins

Thu, 06 Jul 2023 19:45:39 +0200

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: /freebsd/sys/conf/files.powerpc
