037fc336 - kbuild: force all architectures except um to include mandatory-y

Sun, 17 Mar 2019 02:01:09 +0000

kbuild: force all architectures except um to include mandatory-yCurrently, every arch/*/include/uapi/asm/Kbuild explicitly includesthe common Kbuild.asm file. Factor out the duplicated include directivesto scripts/Makefile.asm-generic so that no architecture would opt outof the mandatory-y mechanism.um is not forced to include mandatory-y since it is a very exceptionalcase which does not support UAPI.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/x86/include/uapi/asm/Kbuild

Sun, 17 Mar 2019 02:01:08 +0000

kbuild: warn redundant generic-yThe 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-yIf 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.hI fixed up arch Kbuild files found by this.Suggested-by: Sam Ravnborg Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/x86/include/uapi/asm/Kbuild

Thu, 03 Jan 2019 01:10:37 +0000

arch: remove stale comments "UAPI Header export list"These comments are leftovers of commit fcc8487d477a ("uapi: export allheaders under uapi directories").Prior to that commit, exported headers must be explicitly added toheader-y. Now, all headers under the uapi/ directories are exported.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/x86/include/uapi/asm/Kbuild

c895f6f7 - bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type

Mon, 04 Dec 2017 09:56:44 +0000

bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program typeCommit 0515e5999a466dfe ("bpf: introduce BPF_PROG_TYPE_PERF_EVENTprogram type") introduced the bpf_perf_event_data structure whichexports the pt_regs structure. This is OK for multiple architecturesbut fail for s390 and arm64 which do not export pt_regs. Programsusing them, for example, the bpf selftest fail to compile on thesearchitectures.For s390, exporting the pt_regs is not an option because s390 wantsto allow changes to it. For arm64, there is a user_pt_regs structurethat covers parts of the pt_regs structure for use by user space.To solve the broken uapi for s390 and arm64, introduce an abstracttype for pt_regs and add an asm/bpf_perf_event.h file that concretesthe type. An asm-generic header file covers the architectures thatexport pt_regs today.The arch-specific enablement for s390 and arm64 follows in separatecommits.Reported-by: Thomas Richter Fixes: 0515e5999a466dfe ("bpf: introduce BPF_PROG_TYPE_PERF_EVENT program type")Signed-off-by: Hendrik Brueckner Reviewed-and-tested-by: Thomas Richter Acked-by: Alexei Starovoitov Cc: Arnaldo Carvalho de Melo Cc: Peter Zijlstra Cc: Ingo Molnar Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Namhyung Kim Cc: Arnd Bergmann Cc: Daniel Borkmann Signed-off-by: Daniel Borkmann List of files: /linux-6.15/arch/x86/include/uapi/asm/Kbuild

ae3f4151 - kbuild: replace genhdr-y with generated-y

Fri, 09 Jun 2017 08:29:52 +0000

kbuild: replace genhdr-y with generated-yOriginally, generated-y and genhdr-y had different meaning, likefollows:- generated-y: generated headers (other than asm-generic wrappers)- header-y : headers to be exported- genhdr-y : generated headers to be exported (generated-y + header-y)Since commit fcc8487d477a ("uapi: export all headers under uapidirectories"), headers under UAPI directories are all exported.So, there is no more difference between generated-y and genhdr-y.We see two users of genhdr-y, arch/{arm,x86}/include/uapi/asm/Kbuild.They generate some headers in arch/{arm,x86}/include/generated/uapi/asmdirectories, which are obviously exported.Replace them with generated-y, and abolish genhdr-y.Signed-off-by: Masahiro Yamada Acked-by: Nicolas Dichtel List of files: /linux-6.15/arch/x86/include/uapi/asm/Kbuild

fcc8487d - uapi: export all headers under uapi directories

Mon, 27 Mar 2017 12:20:15 +0000

uapi: export all headers under uapi directoriesRegularly, when a new header is created in include/uapi/, the developerforgets to add it in the corresponding Kbuild file. This error is usuallydetected after the release is out.In fact, all headers under uapi directories should be exported, thus it'suseless to have an exhaustive list.After this patch, the following files, which were not exported, are nowexported (with make headers_install_all):asm-arc/kvm_para.hasm-arc/ucontext.hasm-blackfin/shmparam.hasm-blackfin/ucontext.hasm-c6x/shmparam.hasm-c6x/ucontext.hasm-cris/kvm_para.hasm-h8300/shmparam.hasm-h8300/ucontext.hasm-hexagon/shmparam.hasm-m32r/kvm_para.hasm-m68k/kvm_para.hasm-m68k/shmparam.hasm-metag/kvm_para.hasm-metag/shmparam.hasm-metag/ucontext.hasm-mips/hwcap.hasm-mips/reg.hasm-mips/ucontext.hasm-nios2/kvm_para.hasm-nios2/ucontext.hasm-openrisc/shmparam.hasm-parisc/kvm_para.hasm-powerpc/perf_regs.hasm-sh/kvm_para.hasm-sh/ucontext.hasm-tile/shmparam.hasm-unicore32/shmparam.hasm-unicore32/ucontext.hasm-x86/hwcap2.hasm-xtensa/kvm_para.hdrm/armada_drm.hdrm/etnaviv_drm.hdrm/vgem_drm.hlinux/aspeed-lpc-ctrl.hlinux/auto_dev-ioctl.hlinux/bcache.hlinux/btrfs_tree.hlinux/can/vxcan.hlinux/cifs/cifs_mount.hlinux/coresight-stm.hlinux/cryptouser.hlinux/fsmap.hlinux/genwqe/genwqe_card.hlinux/hash_info.hlinux/kcm.hlinux/kcov.hlinux/kfd_ioctl.hlinux/lightnvm.hlinux/module.hlinux/nbd-netlink.hlinux/nilfs2_api.hlinux/nilfs2_ondisk.hlinux/nsfs.hlinux/pr.hlinux/qrtr.hlinux/rpmsg.hlinux/sched/types.hlinux/sed-opal.hlinux/smc.hlinux/smc_diag.hlinux/stm.hlinux/switchtec_ioctl.hlinux/vfio_ccw.hlinux/wil6210_uapi.hrdma/bnxt_re-abi.hNote that I have removed from this list the files which are generated in everyexported directories (like .install or .install.cmd).Thanks to Julien Floret for the tip to get allsubdirs with a pure makefile command.For the record, note that exported files for asm directories are a mix offiles listed by: - include/uapi/asm-generic/Kbuild.asm; - arch//include/uapi/asm/Kbuild; - arch//include/asm/Kbuild.Signed-off-by: Nicolas Dichtel Acked-by: Daniel Vetter Acked-by: Russell King Acked-by: Mark Salter Acked-by: Michael Ellerman (powerpc)Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/x86/include/uapi/asm/Kbuild

perf kvm: Use defines of kvm eventsCurrently perf-kvm uses string literals for kvm event names, but itworks only for x86, because other architectures may have other names forthose events.To reduce dependence on architecture, we add file withdefines for:- kvm_entry and kvm_exit events,- exit reason field name in kvm_exit event,- length of exit reasons strings,- vcpu_id field name in kvm trace events,and replace literals in perf-kvm.Reviewed-by: Cornelia Huck Reviewed-by David Ahern Signed-off-by: Alexander Yarygin Acked-by: Christian Borntraeger Cc: Christian Borntraeger Cc: Cornelia Huck Cc: David Ahern Cc: Ingo Molnar Cc: Jiri Olsa Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1404397747-20939-2-git-send-email-yarygin@linux.vnet.ibm.comSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/arch/x86/include/uapi/asm/Kbuild
