Wed, 12 Mar 2025 15:52:19 +0000

scripts: get_feat.pl: substitute s390x with s390Both get_feat.pl and list-arch.sh use uname -m to get the machine hardwarename to figure out the current architecture if no architecture is specifiedwith a command line option.This doesn't work for s390, since for 64 bit kernels the hardware name iss390x, while the architecture name within the kernel, as well as in allfeature files is s390.Therefore substitute s390x with s390 similar to what is already done forx86_64 and i386.Signed-off-by: Heiko Carstens Signed-off-by: Jonathan Corbet Link: https://lore.kernel.org/r/20250312155219.3597768-1-hca@linux.ibm.com List of files: /linux/tools/docs/list-arch.sh

Mon, 30 Nov 2020 15:36:32 +0000

scripts: get_feat.pl: use its implementation for list-arch.shAdd support for the same output format as the bash script,and use its implementation instead of the previous one.I opted to do such patch in order to have a single scriptresponsible for parsing Documentation/features andproduce different outputs.As someone may rely on the past format, which is easyto parse it, get_feat.pl now gains a new command withthe same output format as the previous script.As a side effect, the perl script is a lot faster, as it readseach file only once, instead of parsing files several timesvia a for command and grep commands inside it.This patch also changes the features list order to becase-insensitive, in order to better match the output ofthe existing script.Signed-off-by: Mauro Carvalho Chehab Link: https://lore.kernel.org/r/a97f49677805ad4e6b982d02c0db8c9dfbbd20a6.1606748711.git.mchehab+huawei@kernel.orgSigned-off-by: Jonathan Corbet List of files: /linux/tools/docs/list-arch.sh

Sat, 10 Feb 2018 17:00:58 +0000

Documentation/features: Allow comments in arch features filesThe list-arch.sh script considers lines beginning with "#" as match forthe feature table.Given that those tables are never in lines beginning with "#",add a reverse grep on "^#" when matching the "ok/TODO" state ofthe architecture.This allows adding comments within the feature files, for instancedescribing the architecture requirements for the feature in eacharchitecture.Signed-off-by: Mathieu Desnoyers Cc: Jonathan Corbet Cc: Linus Torvalds Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-doc@vger.kernel.orgLink: http://lkml.kernel.org/r/1518282058-24226-1-git-send-email-mathieu.desnoyers@efficios.comSigned-off-by: Ingo Molnar List of files: /linux/tools/docs/list-arch.sh

df8a0dde73069b69c7d6f2a1758857c482d59e18 - Remove "arch" usage in Documentation/features/list-arch.sh

Thu, 21 Jan 2016 10:23:43 +0000

Remove "arch" usage in Documentation/features/list-arch.shCommit 669f6f96c680a741257ada44a28b580df2e1fc25 introducedthe script list-arch.sh, which uses the command "arch":ARCH=${1:-$(arch | sed 's/x86_64/x86/' | sed 's/i386/x86/')}It turns out that the "arch" command does not exist in my system (archdistro). Google found man pages which say "arch is deprecated command sincerelease util-linux 2.13. Use uname -m" (util-linux 2.13 was released in 2007).I also found a debian bug reporting the lack of arch and being told to useuname -m https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=446023But then, why it works in some distros? Apparently coreutils gained anoptional arch command that needs to be explicitly enabled during compilation.Some distros enable it, others don't.

669f6f96c680a741257ada44a28b580df2e1fc25 - Documentation/features: Explain kernel feature descriptions and add visualization script

Wed, 03 Jun 2015 10:39:26 +0000

Documentation/features: Explain kernel feature descriptions and add visualization scriptThe previous patches added arch support matrices for more than 40 generic kernel featuresthat need per architecture support.The structure of the feature descriptions is the following:Each feature has its own directory under Documentation/features/subsystem_name/feature_name/,and the arch-support.txt file shows its current arch porting status.For example, lockdep support is shown the following way: triton:~/tip> cat Documentation/features/locking/lockdep/arch-support.txt # # Feature name: lockdep # Kconfig: LOCKDEP_SUPPORT # description: arch supports the runtime locking correctness debug facility # ----------------------- | arch |status| ----------------------- | alpha: | TODO | | arc: | ok | | arm: | ok | | arm64: | ok | | avr32: | ok | | blackfin: | ok | | c6x: | TODO | | cris: | TODO | | frv: | TODO | | h8300: | TODO | | hexagon: | ok | | ia64: | TODO | | m32r: | TODO | | m68k: | TODO | | metag: | ok | | microblaze: | ok | | mips: | ok | | mn10300: | TODO | | nios2: | TODO | | openrisc: | TODO | | parisc: | TODO | | powerpc: | ok | | s390: | ok | | score: | ok | | sh: | ok | | sparc: | ok | | tile: | ok | | um: | ok | | unicore32: | ok | | x86: | ok | | xtensa: | ok | -----------------------For generic kernel features that need architecture support, thearch-support.txt file in each feature directory shows the archsupport matrix, for all upstream Linux architectures.The meaning of entries in the tables is: | ok | # feature supported by the architecture |TODO| # feature not yet supported by the architecture | .. | # feature cannot be supported by the hardwareThis directory structure can be used in the future to add otherfiles - such as porting guides, testing description, etc.The Documentation/features/ hierarchy may also include generickernel features that works on every architecture, in that casethe arch-support.txt file will list every architecture assupported.To list an architecture's unsupported features, just do somethinglike: triton:~/tip> git grep -lE 'x86.*TODO' Documentation/features/*/*/arch-support.txt Documentation/features/lib/strncasecmp/arch-support.txt Documentation/features/time/arch-tick-broadcast/arch-support.txtwhich will print the list of not yet supported features.The Documentation/features/list-arch.sh script will print the currentsupport matrix of one architecture: triton:~/tip> Documentation/features/list-arch.sh # # Kernel feature support matrix of the 'x86' architecture: # core/ BPF-JIT : ok | HAVE_BPF_JIT # arch supports BPF JIT optimizations core/ generic-idle-thread : ok | GENERIC_SMP_IDLE_THREAD # arch makes use of the generic SMP idle thread facility core/ jump-labels : ok | HAVE_ARCH_JUMP_LABEL # arch supports live patched, high efficiency branches core/ tracehook : ok | HAVE_ARCH_TRACEHOOK # arch supports tracehook (ptrace) register handling APIs debug/ gcov-profile-all : ok | ARCH_HAS_GCOV_PROFILE_ALL # arch supports whole-kernel GCOV code coverage profiling debug/ KASAN : ok | HAVE_ARCH_KASAN # arch supports the KASAN runtime memory checker debug/ kgdb : ok | HAVE_ARCH_KGDB # arch supports the kGDB kernel debugger debug/ kprobes : ok | HAVE_KPROBES # arch supports live patched kernel probe debug/ kprobes-on-ftrace : ok | HAVE_KPROBES_ON_FTRACE # arch supports combined kprobes and ftrace live patching debug/ kretprobes : ok | HAVE_KRETPROBES # arch supports kernel function-return probes debug/ optprobes : ok | HAVE_OPTPROBES # arch supports live patched optprobes debug/ stackprotector : ok | HAVE_CC_STACKPROTECTOR # arch supports compiler driven stack overflow protection debug/ uprobes : ok | ARCH_SUPPORTS_UPROBES # arch supports live patched user probes debug/ user-ret-profiler : ok | HAVE_USER_RETURN_NOTIFIER # arch supports user-space return from system call profiler io/ dma-api-debug : ok | HAVE_DMA_API_DEBUG # arch supports DMA debug facilities io/ dma-contiguous : ok | HAVE_DMA_CONTIGUOUS # arch supports the DMA CMA (continuous memory allocator) io/ dma_map_attrs : ok | HAVE_DMA_ATTRS # arch provides dma_*map*_attrs() APIs io/ sg-chain : ok | ARCH_HAS_SG_CHAIN # arch supports chained scatter-gather lists lib/ strncasecmp : TODO | __HAVE_ARCH_STRNCASECMP # arch provides an optimized strncasecmp() function locking/ cmpxchg-local : ok | HAVE_CMPXCHG_LOCAL # arch supports the this_cpu_cmpxchg() API locking/ lockdep : ok | LOCKDEP_SUPPORT # arch supports the runtime locking correctness debug facility locking/ queued-rwlocks : ok | ARCH_USE_QUEUED_RWLOCKS # arch supports queued rwlocks locking/ queued-spinlocks : ok | ARCH_USE_QUEUED_SPINLOCKS # arch supports queued spinlocks locking/ rwsem-optimized : ok | Optimized asm/rwsem.h # arch provides optimized rwsem APIs perf/ kprobes-event : ok | HAVE_REGS_AND_STACK_ACCESS_API # arch supports kprobes with perf events perf/ perf-regs : ok | HAVE_PERF_REGS # arch supports perf events register access perf/ perf-stackdump : ok | HAVE_PERF_USER_STACK_DUMP # arch supports perf events stack dumps sched/ numa-balancing : ok | ARCH_SUPPORTS_NUMA_BALANCING # arch supports NUMA balancing seccomp/ seccomp-filter : ok | HAVE_ARCH_SECCOMP_FILTER # arch supports seccomp filters time/ arch-tick-broadcast : TODO | ARCH_HAS_TICK_BROADCAST # arch provides tick_broadcast() time/ clockevents : ok | GENERIC_CLOCKEVENTS # arch support generic clock events time/ context-tracking : ok | HAVE_CONTEXT_TRACKING # arch supports context tracking for NO_HZ_FULL time/ irq-time-acct : ok | HAVE_IRQ_TIME_ACCOUNTING # arch supports precise IRQ time accounting time/ modern-timekeeping : ok | !ARCH_USES_GETTIMEOFFSET # arch does not use arch_gettimeoffset() anymore time/ virt-cpuacct : ok | HAVE_VIRT_CPU_ACCOUNTING # arch supports precise virtual CPU time accounting vm/ ELF-ASLR : ok | ARCH_HAS_ELF_RANDOMIZE # arch randomizes the stack, heap and binary images of ELF binaries vm/ huge-vmap : ok | HAVE_ARCH_HUGE_VMAP # arch supports the ioremap_pud_enabled() and ioremap_pmd_enabled() VM APIs vm/ ioremap_prot : ok | HAVE_IOREMAP_PROT # arch has ioremap_prot() vm/ numa-memblock : ok | HAVE_MEMBLOCK_NODE_MAP # arch supports NUMA aware memblocks vm/ PG_uncached : ok | ARCH_USES_PG_UNCACHED # arch supports the PG_uncached page flag vm/ pmdp_splitting_flush : ok | __HAVE_ARCH_PMDP_SPLITTING_FLUSH # arch supports the pmdp_splitting_flush() VM API vm/ pte_special : ok | __HAVE_ARCH_PTE_SPECIAL # arch supports the pte_special()/pte_mkspecial() VM APIs vm/ THP : ok | HAVE_ARCH_TRANSPARENT_HUGEPAGE # arch supports transparent hugepagesCc: Cc: Cc: Cc: Andrew Morton Cc: H.
