Details
taskset sets or gets CPU affinity.
It can be used to run a command on one or more specified CPU cores.
The default method is to specify the cores to use as a hexadecimal bitmask.
For a quad core CPU this can be 1 / 2 / 4 / 8 for each single core or mixes up to F for all cores.
There's an optional -c parameter to specify the core numers in a comma separated list like -c 1,2,3,4,
but it's mostly not compiled in in FRITZ!OS even if taskset --help lists it, so get used to the bitmask!
Let's benchmark the 4 cores of a Dakota based 7530 fw 7.29:
root@fritz1:/var/mod/root# taskset -p $PPID pid 19780's current affinity mask: f root@fritz1:/var/mod/root# taskset 1 dhrystone 10000000 Dhrystone MIPS: 642.4 root@fritz1:/var/mod/root# taskset 2 dhrystone 10000000 Dhrystone MIPS: 638.1 root@fritz1:/var/mod/root# taskset 4 dhrystone 10000000 Dhrystone MIPS: 641.7 root@fritz1:/var/mod/root# taskset 8 dhrystone 10000000 Dhrystone MIPS: 641.7 root@fritz1:/var/mod/root# taskset F dhrystone 10000000 Dhrystone MIPS: 641.7
You see, dhrystone measures single core integer performance and does not benefit from multiple cores.
See also the sched_getaffinity(2) and sched_setaffinity(2) man pages. This is what taskset calls.

GPL-Browser
Daily updated index of all taskset code findings on the GPL-Browser. Last update: 2025-01-23 05:00 GMT.
The Browse column points to the Path containing the respective source code on the gpl.boxmatrix.info service.
The SoC column lists the Chip-Codenames, the Model column lists the nicks of the Box-Models.
The Diff column links the comparison of the AVM Kernel to the pristine original from Kernel.org.
The Download column links the full tarball the respective directory content is extracted from.
The presence of the source does not mean it fits the respective model and architecture. See the Model-Matrix where it's used.

Showing all models using this command. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list is merged from Firmware-Probes of all known AVM firmware for a model, including Recovery.exe and Labor-Files.
The path <bb> means the applet could be located in the busybox binary and could be called busybox taskset.
If a path is shown and no <bb> marker, then this is a dead link to a missing applet.
