However, this plugin offers more flexibility, as it allows tuning of individual interrupts with different affinities. When using the `irq` plugin, make sure to disable IRQ processing in the `scheduler` plugin by setting its option [option]`irq_process=false`. The plugin handles individual IRQs as devices and multiple plugin instances can be defined, each addressing different devices/irqs. The device names used by the plugin are `irq`, where `` is the IRQ number. The special device `DEFAULT` controls values written to `/proc/irq/default_smp_affinity`, which applies to all non-active IRQs. The option [option]`affinity` controls the IRQ affinity to be set. It is a string in "cpulist" format (such as `1,3-4`). If the configured affinity is empty, then the affinity of the respective IRQs is not touched. The option [option]`mode` is a string which can either be `set` (default) or `intersect`. In `set` mode the [option]`affinity` is always written as configured, whereas in `intersect` mode, the new affinity will be calculated as the intersection of the current and the configured affinity. If that intersection is empty, the configured affinity will be used. .Moving all IRQs to CPU0, except irq16, which is directed to CPU2 ==== ---- [irq_special] type=irq devices=irq16 affinity=2 [irq] affinity=0 ---- ==== c sB<\\V` WW4WVWx4/VnR#N)superrr _irqs) rZmonitor_repositoryZstorage_factoryZhardware_inventoryZdevice_matcherZdevice_matcher_udevZplugin_instance_factoryZ global_cfgZ variables __class__s &&&&&&&&&rr ZIrqPlugin.__init__:s* 4!"4GYk~Zdp$*r c sNRVn\4Vn\4Vn\P !R4Fp\P PRV4p\P PV4'gKJVP4'gKb\V4pW0PV&VPPVP4K \R4pRVn W@PR&VPPVP4R#)z2Read /proc/irq to collect devices Tz /proc/irqDEFAULTN)_devices_supportedset _free_devices_assigned_devicesosZlistdirZpathZjoinZisdirZisdigitrrZaddr)rZiZpinfoZ default_infos& r _init_devicesZIrqPlugin._init_devicesAs!$u$5$ ::k "a ww||K#1ggmmA199;; 1:DJJqM4;;' ##,!,&**Y,,-r csRRRR/#)affinitymoder)Zclss&r_get_config_optionsZIrqPlugin._get_config_optionsSsr 5 r csRVnRVnVPPVPP R44pVP PV4p\VP44^8Xd/\PRVP,4RVn M?\V4^8Xd0\PRVP: RV: R24RVn VPPVPP R44pVR 9d:\PR V: R VP: R 24RVPR&R #R #)TFrz;Instance '%s' configured with empty affinity.
