fb54ea1e - dimlib: use -y instead of -objs in Makefile

Wed, 21 Aug 2024 15:51:04 +0000

dimlib: use *-y instead of *-objs in Makefile*-objs suffix is reserved rather for (user-space) host programs whileusually *-y suffix is used for kernel drivers (although *-objs works forthat purpose for now).Let's correct the old usages of *-objs in Makefiles.Link: https://lkml.kernel.org/r/20240821155140.611514-1-andriy.shevchenko@linux.intel.comSigned-off-by: Andy Shevchenko Acked-by: Florian Fainelli Reviewed-by: Alexander Lobakin Cc: Rasmus Villemoes Cc: Tal Gilboa Signed-off-by: Andrew Morton List of files: /linux-6.15/lib/dim/Makefile

0d5044b4 - lib: Allow for the DIM library to be modular

Mon, 06 May 2024 17:50:40 +0000

lib: Allow for the DIM library to be modularAllow the Dynamic Interrupt Moderation (DIM) library to be built as amodule. This is particularly useful in an Android GKI (Google KernelImage) configuration where everything is built as a module, includingEthernet controller drivers. Having to build DIMLIB into the kernelimage with potentially no user is wasteful.Signed-off-by: Florian Fainelli Reviewed-by: Alexander Lobakin Link: https://lore.kernel.org/r/20240506175040.410446-1-florian.fainelli@broadcom.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/lib/dim/Makefile

b16838c6 - kbuild: trace functions in subdirectories of lib/

Tue, 07 Jul 2020 09:21:17 +0000

kbuild: trace functions in subdirectories of lib/ccflags-remove-$(CONFIG_FUNCTION_TRACER) += $(CC_FLAGS_FTRACE)exists here in sub-directories of lib/ to keep the behavior ofcommit 2464a609ded0 ("ftrace: do not trace library functions").Since that commit, not only the objects in lib/ but also the ones inthe sub-directories are excluded from ftrace (although the commitdescription did not explicitly mention this).However, most of library functions in sub-directories are not so hot.Re-add them to ftrace.Going forward, only the objects right under lib/ will be excluded.Cc: Ingo Molnar Signed-off-by: Masahiro Yamada Acked-by: Steven Rostedt (VMware) List of files: /linux-6.15/lib/dim/Makefile

15d5761a - kbuild: introduce ccflags-remove-y and asflags-remove-y

Tue, 07 Jul 2020 09:21:16 +0000

kbuild: introduce ccflags-remove-y and asflags-remove-yCFLAGS_REMOVE_.o filters out flags when compiling a particularobject, but there is no convenient way to do that for every object ina directory.Add ccflags-remove-y and asflags-remove-y to make it easily.Use ccflags-remove-y to clean up some Makefiles.The add/remove order works as follows: [1] KBUILD_CFLAGS specifies compiler flags used globally [2] ccflags-y adds compiler flags for all objects in the current Makefile [3] ccflags-remove-y removes compiler flags for all objects in the current Makefile (New feature) [4] CFLAGS_ adds compiler flags per file. [5] CFLAGS_REMOVE_ removes compiler flags per file.Having [3] before [4] allows us to remove flags from most (but not all)objects in the current Makefile.For example, kernel/trace/Makefile removes $(CC_FLAGS_FTRACE)from all objects in the directory, then adds it back totrace_selftest_dynamic.o and CFLAGS_trace_kprobe_selftest.oThe same applies to lib/livepatch/Makefile.Please note ccflags-remove-y has no effect to the sub-directories.In contrast, the previous notation got rid of compiler flags also fromall the sub-directories.The following are not affected because they have no sub-directories: arch/arm/boot/compressed/ arch/powerpc/xmon/ arch/sh/ kernel/trace/However, lib/ has several sub-directories.To keep the behavior, I added ccflags-remove-y to all Makefilesin subdirectories of lib/, except the following: lib/vdso/Makefile - Kbuild does not descend into this Makefile lib/raid/test/Makefile - This is not used for the kernel buildI think commit 2464a609ded0 ("ftrace: do not trace library functions")excluded too much. In the next commit, I will remove ccflags-remove-yfrom the sub-directories of lib/.Suggested-by: Sami Tolvanen Signed-off-by: Masahiro Yamada Acked-by: Steven Rostedt (VMware) Acked-by: Michael Ellerman (powerpc)Acked-by: Brendan Higgins (KUnit)Tested-by: Anders Roxell List of files: /linux-6.15/lib/dim/Makefile

f4915455 - linux/dim: Implement RDMA adaptive moderation (DIM)

Mon, 08 Jul 2019 10:59:02 +0000

linux/dim: Implement RDMA adaptive moderation (DIM)RDMA DIM implements a different algorithm from net DIM and is based oncompletions which is how we can implement interrupt moderation in RDMA.The algorithm optimizes for number of completions and ratio betweencompletions and events. In order to avoid long latencies, theimplementation performs fast reduction of moderation level when thetraffic changes.Signed-off-by: Yamin Friedman Reviewed-by: Max Gurtovoy Reviewed-by: Sagi Grimberg Signed-off-by: Saeed Mahameed Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe List of files: /linux-6.15/lib/dim/Makefile

linux/dim: Move implementation to .c filesMoved all logic from dim.h and net_dim.h to dim.c and net_dim.c.This is both more structurally appealing and would allow to onlyexpose externally used functions.Signed-off-by: Tal Gilboa Signed-off-by: Saeed Mahameed List of files: /linux-6.15/lib/dim/Makefile
