Arch Linux User Repository

Official binary builds for various x86_64 ISA levels are available here.

i stumble upon this when trying to compile: CC kernel/sched/bfs.o kernel/sched/bfs.c:528:20: error: function declaration isn’t a prototype [-Werror=strict-prototypes] static inline void grq_priodl_lock() ^ kernel/sched/bfs.c:533:20: error: function declaration isn’t a prototype [-Werror=strict-prototypes] static inline void grq_priodl_unlock() ^ cc1: some warnings being treated as errors scripts/Makefile.build:258: recipe for target 'kernel/sched/bfs.o' failed

upkg, synched configs with arch-linux-pf except for tomoyo which is enabled but makes no performance downsides

build keeps failing in package_linux-pf() where it makes a symlink to extramodules..... why?

These are the performance suspects taken from the diff between 3.19.3-3-ARCH and 3.19.4-pf: *********** PF specific ************ -CONFIG_CGROUP_SCHED=y -CONFIG_FAIR_GROUP_SCHED=y -CONFIG_CFS_BANDWIDTH=y -CONFIG_RT_GROUP_SCHED=y +CONFIG_SCHED_BFS=y -CONFIG_SCHED_AUTOGROUP=y -CONFIG_IOSCHED_DEADLINE=y -CONFIG_IOSCHED_CFQ=y +CONFIG_IOSCHED_DEADLINE=m +CONFIG_IOSCHED_CFQ=m -CONFIG_DEFAULT_CFQ=y +CONFIG_IOSCHED_BFQ=y +CONFIG_CGROUP_BFQIO=y +CONFIG_DEFAULT_BFQ=y -CONFIG_DEFAULT_IOSCHED="cfq" +CONFIG_DEFAULT_IOSCHED="bfq" -CONFIG_KERNEL_GZIP=y +CONFIG_KERNEL_LZ4=y +CONFIG_UKSM=y -CONFIG_HZ_300=y -CONFIG_HZ=300 +CONFIG_HZ_1000=y +CONFIG_HZ=1000 +CONFIG_TOI_CORE=y +CONFIG_TOI_FILE=m +CONFIG_TOI_SWAP=m +CONFIG_TOI_CRYPTO=m +CONFIG_TOI_USERUI=m +CONFIG_TOI_USERUI_DEFAULT_PATH="/usr/sbin/tuxoniceui" +CONFIG_TOI_DEFAULT_IMAGE_SIZE_LIMIT=-2 +CONFIG_TOI_REPLACE_SWSUSP=y +CONFIG_TOI_IGNORE_LATE_INITCALL=y +CONFIG_TOI_DEFAULT_WAIT=25 +CONFIG_TOI_DEFAULT_EXTRA_PAGES_ALLOWANCE=7000 +CONFIG_TOI=y +CONFIG_TOI_EXPORTS=y +CONFIG_TOI_ZRAM_SUPPORT=y +CONFIG_AUFS_FS=m +CONFIG_AUFS_BRANCH_MAX_127=y +CONFIG_AUFS_SBILIST=y +CONFIG_AUFS_HNOTIFY=y +CONFIG_AUFS_HFSNOTIFY=y +CONFIG_AUFS_EXPORT=y +CONFIG_AUFS_INO_T_64=y +CONFIG_AUFS_RDU=y +CONFIG_AUFS_SHWH=y +CONFIG_AUFS_BR_RAMFS=y +CONFIG_AUFS_BR_FUSE=y +CONFIG_AUFS_POLL=y +CONFIG_AUFS_BR_HFSPLUS=y +CONFIG_AUFS_BDEV_LOOP=y ************************************************* ****** performance hogs? ************************ +CONFIG_AUDIT=y +CONFIG_AUDITSYSCALL=y +CONFIG_AUDIT_WATCH=y +CONFIG_AUDIT_TREE=y +CONFIG_NETFILTER_XT_TARGET_AUDIT=m -CONFIG_F2FS_FS_SECURITY=y -CONFIG_F2FS_CHECK_FS=y +CONFIG_SECURITY_NETWORK=y +CONFIG_SECURITY_TOMOYO=y +CONFIG_SECURITY_TOMOYO_MAX_ACCEPT_ENTRY=2048 +CONFIG_SECURITY_TOMOYO_MAX_AUDIT_LOG=1024 +CONFIG_SECURITY_TOMOYO_POLICY_LOADER="/sbin/tomoyo-init" +CONFIG_SECURITY_TOMOYO_ACTIVATION_TRIGGER="/usr/lib/systemd/systemd" +CONFIG_SECURITY_APPARMOR=y +CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=0 +CONFIG_SECURITY_APPARMOR_HASH=y +CONFIG_INTEGRITY_AUDIT=y ************************************************ ******** other ********************************* -CONFIG_TICK_CPU_ACCOUNTING=y +CONFIG_IRQ_TIME_ACCOUNTING=y -CONFIG_NUMA_BALANCING=y -CONFIG_NUMA_BALANCING_DEFAULT_ENABLED=y -CONFIG_CGROUP_CPUACCT=y -CONFIG_AIX_PARTITION=y +CONFIG_X86_INTEL_USERCOPY=y +CONFIG_X86_USE_PPRO_CHECKSUM=y +CONFIG_SMT_NICE=y -CONFIG_NUMA=y -CONFIG_AMD_NUMA=y -CONFIG_X86_64_ACPI_NUMA=y -CONFIG_NODES_SPAN_OTHER_NODES=y -CONFIG_NODES_SHIFT=6 -CONFIG_NEED_MULTIPLE_NODES=y -CONFIG_USE_PERCPU_NUMA_NODE_ID=y -CONFIG_ACPI_NUMA=y +CONFIG_RTC_DRV_RX4581=m -CONFIG_SXGBE_ETH=m -CONFIG_MFD_RTSX_USB=m -CONFIG_MFD_RN5T618=m -CONFIG_MFD_SI476X_CORE=m +CONFIG_EFI_VARS=m +CONFIG_EFI_VARS_PSTORE=m -CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE=0x0 +CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE=0x1 -CONFIG_CRYPTO_SHA1=m +CONFIG_CRYPTO_SHA1=y -CONFIG_CRYPTO_DEV_CCP=y -CONFIG_CRYPTO_DEV_CCP_DD=m -CONFIG_CRYPTO_DEV_CCP_CRYPTO=m

@Thaodan: I used to copy over the ARCH config once every major kernel release and just enable the extra pf-patchset features, i.e. BFS, Hz freq --> 1000, BFQ and TuxOnIce. It's less than a minute's effort and helps to keep the config in order. See also README.maintainers at https://bitbucket.org/nous/linux-pf/src. Cheers!

Well, I won't post the full list of config settings that aren't the same as there are many (can be seen by doing a diff), for example there are the CONFIG_SECURITY_* ones which may lower the performance.

It's on my list, but please if you have something to complain give more infos, more detail

Could you please fix the configs to match the official archlinux ones for the non -pf settings, there are still many things that are not in sync. Most of them were modified or removed at some point, and that wasn't changed in -pf.

yes this is true, but you could update this too.

Modules tuxonice_compress, tuxonice_swap and tuxonice_userui are no longer provided by the kernel, so the wiki pages about tuxonice and linux-pf need to be updated, i.e.update the line about MODULES in mkinitcpio.conf.
