qualcommax: enhance smp_affinity (log, uci, syntax) 1.) Changed logic of `set_affinity` to now use physical cores rather than knowing the bitmask. Rather than having to know a bitmask, users can provide a numerical instance of one or more CPU cores (numbered 0-63). This is done via function `cpus_to_bitmask`. Functions Added: a.) bitmask_to_cpus - Takes a bitmask of CPUs and returns a list of CPU numbers. (i.e. `bitmask_to_cpus "f"` -> 0,1,2,3) b.) cpus_to_bitmask - Takes a comma/space or range list of CPUs and returns a bitmask. Example: `cpus_to_bitmask "2,3"` -> c `cpus_to_bitmask "0,1,2,3"` -> f `cpus_to_bitmask "1,3"` -> a With or without quotes `cpus_to_bitmask "1 3"` -> a `cpus_to_bitmask 1 3` -> a 2.) Added UCI options: enable - to enable/disable the script from running. [default 1 (on)] enable_log - to enable/disable logging output to `logger`.[default 1 (on)] Log output: ``` Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(87) reo2host-destination-ring1 to CPU 0 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(88) reo2host-destination-ring2 to CPU 1 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(89) reo2host-destination-ring3 to CPU 2 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(90) reo2host-destination-ring4 to CPU 3 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(79) wbm2host-tx-completions-ring1 to CPU 1 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(83) wbm2host-tx-completions-ring2 to CPU 2 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(85) wbm2host-tx-completions-ring3 to CPU 3 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(73) ppdu-end-interrupts-mac1 to CPU 1 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(77) ppdu-end-interrupts-mac2 to CPU 2 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(75) ppdu-end-interrupts-mac3 to CPU 3 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(32) edma_txcmpl to CPU 3 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(33) edma_rxfill to CPU 3 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(35) edma_rxdesc to CPU 3 Mon Apr 8 23:00:01 2024 user.notice smp_affinity: Pinning IRQ(36) edma_misc to CPU 3 ``` Output of `/proc/interrupts`: ``` 69: 0 0 0 0 GIC-0 209 Edge rxdma2host-destination-ring-mac1 70: 0 0 0 0 GIC-0 211 Edge rxdma2host-destination-ring-mac3 71: 0 0 0 0 GIC-0 210 Edge rxdma2host-destination-ring-mac2 72: 2435 0 0 0 GIC-0 321 Edge reo2host-status 73: 268427 8011 0 0 GIC-0 261 Edge ppdu-end-interrupts-mac1 74: 2 0 0 0 GIC-0 255 Edge rxdma2host-monitor-status-ring-mac1 75: 176169 0 4 10035 GIC-0 263 Edge ppdu-end-interrupts-mac3 76: 2 0 0 0 GIC-0 260 Edge rxdma2host-monitor-status-ring-mac3 77: 0 0 0 0 GIC-0 262 Edge ppdu-end-interrupts-mac2 78: 0 0 0 0 GIC-0 256 Edge rxdma2host-monitor-status-ring-mac2 79: 3428 3123 0 0 GIC-0 189 Edge wbm2host-tx-completions-ring1 80: 0 0 0 0 GIC-0 323 Edge reo2ost-exception 81: 178 0 0 0 GIC-0 322 Edge wbm2host-rx-release 82: 0 0 0 0 GIC-0 212 Edge host2rxdma-host-buf-ring-mac1 83: 6524 0 13712 0 GIC-0 190 Edge wbm2host-tx-completions-ring2 84: 4 0 0 0 GIC-0 235 Edge host2rxdma-host-buf-ring-mac3 85: 560 0 0 1979 GIC-0 191 Edge wbm2host-tx-completions-ring3 86: 0 0 0 0 GIC-0 215 Edge host2rxdma-host-buf-ring-mac2 87: 4520 0 0 0 GIC-0 267 Edge reo2host-destination-ring1 88: 2231 2811 0 0 GIC-0 268 Edge reo2host-destination-ring2 89: 2180 0 2512 0 GIC-0 271 Edge reo2host-destination-ring3 90: 1990 0 0 2321 GIC-0 320 Edge reo2host-destination-ring4 ``` 3.)
