* hwclock: use CMOS clock only if availableCarlos Santos2019-07-151-2/+5
| | | | | | | | | | | | - Add --disable-hwclock-cmos configuration argument - Add USE_HWCLOCK_CMOS (enabled by default for i386/x86_64) - Add define(USE_HWCLOCK_CMOS) - Compile hwclock-cmos.c only if USE_HWCLOCK_CMOS is true - Remove all unnecessary #ifdefs from hwclock-cmos.c - Add #ifdef USE_HWCLOCK_CMOS around the determine_clock_access_method() call in hwclock.c Signed-off-by: Carlos Santos <unixmania@gmail.com>

* hwclock: use monotonic time to measure how long setting time takesSami Kerola2019-01-121-1/+3
| | | | | | | | | Earlier gettimeofday() was affected by discontinuous jumps. Measuring how long time it takes to set time using function that effected by the very thing being measured makes head spin. Lets make this less confusing with monotonic clock that ticks on without jumps. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* lscpu: Decode ARM CPUsRiku Voipio2018-01-191-0/+1
| | | | | | | | Since the kernel developers have refused to make /proc/cpuinfo user understandable, implement mapping in userspace. lscpu is available for most users via util-linux, so store the information here. Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
* lsns: add nsfs columnMasatake YAMATO2017-11-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nsfs provides kernel level interface for assigning logical name to a namespace. Following message is quoted from git log of linux kernel: commit 0226f4923f6c9b40cfa1c1c1b19a6ac6b3924ead Author: Al Viro <viro@zeniv.linux.org.uk> Date: Tue Dec 6 12:21:54 2011 -0500 vfs: take /proc/*/mounts and friends to fs/proc_namespace.c rationale: that stuff is far tighter bound to fs/namespace.c than to the guts of procfs proper. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> /proc/self/mountinfo lists the logical names for namespaces: ... 652 81 0:3 net:[4026532579] /tmp/XYZ rw shared:192 - nsfs nsfs rw,seclabel ... In the lines /tmp/XYZ is a logical name for 4026532579 of net namespace. This patch adds nsfs column. It seems that the logical name is used only in "ip netns" now. So the column is disabled by default. Use '--type=net' or '-o NSFS' options to enable it. This feature and the way to implementation using multi lines in a column is Suggested by Karel Zak.

* chmem: new toolHeiko Carstens2016-11-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the s390 specific chmem tool to util-linux. The chmem tool was originally written in perl and is part of the s390-tools package which can be found here: https://www.ibm.com/developerworks/linux/linux390/s390-tools.html Given that the tool is architecture independent, there is no reason to keep it in an s390 specific repository. It seems to be useful for other architectures as well. This patch converts the tool to C and adds it to util-linux, while the command line options stay compatible. The only exception is the option "-v" which used to be the short form of "--version". That got changed to "-V" so it behaves like most other tools contained within util-linux. The chmem tool can be used to set memory online or offline. This can be achieved by specifying a memory range: Memory Block 19 (0x0000000130000000-0x000000013fffffff) disabled or by specifying a size where chmem will automatically select memory blocks: Memory Block 21 (0x0000000150000000-0x000000015fffffff) disable failed Memory Block 18 (0x0000000120000000-0x000000012fffffff) disabled Memory Block 17 (0x0000000110000000-0x000000011fffffff) disabled Memory Block 16 (0x0000000100000000-0x000000010fffffff) disabled Memory Block 15 (0x00000000f0000000-0x00000000ffffffff) disabled or by specifying memory block numbers instead of address ranges: Memory Block 15 (0x00000000f0000000-0x00000000ffffffff) disabled Memory Block 16 (0x0000000100000000-0x000000010fffffff) disabled Memory Block 17 (0x0000000110000000-0x000000011fffffff) disabled Memory Block 18 (0x0000000120000000-0x000000012fffffff) disabled This is based on a patch from Clemens von Mann.

* lsmem: new toolHeiko Carstens2016-11-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the s390 specific lsmem tool to util-linux. The lsmem tool was originally written in perl and is part of the s390-tools package which can be found here: https://www.ibm.com/developerworks/linux/linux390/s390-tools.html Given that the tool is architecture independent, there is no reason to keep it in an s390 specific repository.

The only exception is the option "-v" which used to be the short form of "--version". That got changed to "-V" so it behaves like most other tools contained within util-linux. The lsmem tool inspect the contents of /sys/devices/system/memory and prints a summary output similar to what lscpu does: RANGE SIZE STATE REMOVABLE BLOCK 0x0000000000000000-0x000000005fffffff 1,5G online yes 0-5 0x0000000060000000-0x000000007fffffff 512M online no 6-7 0x0000000080000000-0x000000013fffffff 3G online yes 8-19 0x0000000140000000-0x000000014fffffff 256M offline - 20 0x0000000150000000-0x000000017fffffff 768M online no 21-23 Memory block size : 256M Total online memory : 5,8G Total offline memory: 256M In order to keep the output small the tool merges subsequent address ranges where the attributes are identical. To avoid merging of line the "-a" option can be used. The lsmem tool also has "--extendend" and "--parsable" option which can be used to customize the output, e.g. limit the output to specified columns. This is quite similar to what the lscpu tool does. This is based on a patch from Clemens von Mann. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

* lscpu: Print physical cpu informationSukadev Bhattiprolu2015-12-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lscpu currently prints information for CPUs configured in the system. In case of KVM or other virtualized guest operating systems, this refers to the virtual system, and bears no relation to the physical topology of the system. It would be useful if lscpu could also display the physical topology info when available: $ ./lscpu Architecture: ppc64le Byte Order: Little Endian CPU(s): 16 On-line CPU(s) list: 0-15 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 16 NUMA node(s): 1 Model: IBM pSeries (emulated by qemu) Hypervisor vendor: KVM Virtualization type: para L1d cache: 64K L1i cache: 32K NUMA node0 CPU(s): 0-15 Physical sockets: 2 <<< New Physical chips: 4 <<< New Physical cores/chip: 4 <<< New For now, physical topology information is available on platforms that support the following RTAS (Real time abstraction service) call provided by librtas: rtas_get_sysparm(PROCESSOR_MODULE_INFO). Currently this call is available to the PowerVM (pHYP) guests on PowerPC. With a patch propoosed to PowerKVM, this RTAS call would also be available to PowerKVM guests.

* build-sys: support unshare.staticGeorg Schiesser2015-05-181-0/+8
| | | | | | | | | | This patch adds support for building a static version of unshare. We need to add unshare to the list of possible static programs, and provide build flags for the compiler and linker, which are equivalent to the flags of the non-static program, except additional static linking.

* build-sys: fix parallel builds w/setarch linksMike Frysinger2015-05-051-0/+1
| | | | | | | | | | | | | | The symlink generation tries to write to the sys-utils/ subdir but does not make sure that dir exists. This can sometimes lead to parallel build failures when building out-of-tree like: ... echo ".so man8/setarch.8" > sys-utils/linux64.8 /bin/bash: sys-utils/linux64.8: No such file or directory Makefile:11503: recipe for target 'sys-utils/linux64.8' failed make: *** [sys-utils/linux64.8] Error 1 References: https://bugs.gentoo.org/511812 Signed-off-by: Mike Frysinger <vapier@chromium.org>
