864 | * Consumer Histogram - NAPI RX Packet processing | |
865 | * ----------------------------------------------- | |
866 | * On Each CPU, when the NAPI RX Packet processing call back was invoked | |
867 | * how many packets were processed is captured in this data structure. | |
868 | * Now its difficult to capture the "exact" number of packets processed. | |
869 | * So considering the packet counter to be a 32 bit one, we have a | |
870 | * bucket with 8 bins (2^1, 2^2 ... 2^8). The "number" of packets | |
871 | * processed is rounded off to the next power of 2 and put in the | |
872 | * approriate "bin" the value in the bin gets incremented. | |
873 | * For example, assume that in CPU 1 if NAPI Rx runs 3 times | |
874 | * and the packet count processed is as follows (assume the bin counters are 0) | |
875 | * iteration 1 - 10 (the bin counter 2^4 increments to 1) | |
876 | * iteration 2 - 30 (the bin counter 2^5 increments to 1) | |
877 | * iteration 3 - 15 (the bin counter 2^4 increments by 1 to become 2) | |

1249 | * The CPU Candidacy Algorithm | |
1250 | * ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
1251 | * The available CPUs for selection are divided into two groups | |
1252 | * Primary Set - A CPU mask that carries the First Choice CPUs | |
1253 | * Secondary Set - A CPU mask that carries the Second Choice CPUs. | |
1254 | * | |
1255 | * There are two types of Job, that needs to be assigned to | |
1256 | * the CPUs, from one of the above mentioned CPU group. The Jobs are | |
1257 | * 1) Rx Packet Processing - napi_cpu | |
1258 | * 2) Completion Processiong (Tx, RX) - compl_cpu | |
1259 | * | |
1260 | * To begin with both napi_cpu and compl_cpu are on CPU0. Whenever a CPU goes | |
1261 | * on-line/off-line the CPU candidacy algorithm is triggerd. The candidacy | |
1262 | * algo tries to pickup the first available non boot CPU (CPU0) for napi_cpu. | |
1263 | * If there are more processors free, it assigns one to compl_cpu. | |
1264 | * It also tries to ensure that both napi_cpu and compl_cpu are not on the same | |
1265 | * CPU, as much as possible. | |
1266 | * | |
1267 | * By design, both Tx and Rx completion jobs are run on the same CPU core, as it | |
1268 | * would allow Tx completion skb's to be released into a local free pool from | |
1269 | * which the rx buffer posts could have been serviced. it is important to note | |
1270 | * that a Tx packet may not have a large enough buffer for rx posting. | |

3020 | * registered to CPU hotplug notifier. This call back happens from Worker | |
3021 | * context. The dhd_napi_schedule_on is also from worker context. | |
3022 | * Note that both of this can run on two different CPUs at the same time. | |
3023 | * So we can possibly have a window where a given CPUn is being brought | |
3024 | * down from CPUm while we try to run a function on CPUn. | |
3025 | * To prevent this its better have the whole code to execute an SMP | |
3026 | * function under get_online_cpus. | |
3027 | * This function call ensures that hotplug mechanism does not kick-in | |
3028 | * until we are done dealing with online CPUs | |
3029 | * If the hotplug worker is already running, no worries because the | |
3030 | * candidacy algo would then reflect the same in dhd->rx_napi_cpu. | |
3031 | * | |
3032 | * The below mentioned code structure is proposed in | |
3033 | * https://www.kernel.org/doc/Documentation/cpu-hotplug.txt | |

3036 | * work specific to this cpu is in progress | |
3037 | * | |
3038 | * According to the documentation calling get_online_cpus is NOT required, if | |
