|
* approriate "bin" the value in the bin gets incremented.
|
|
* For example, assume that in CPU 1 if NAPI Rx runs 3 times
|
|
* and the packet count processed is as follows (assume the bin counters are 0)
|
|
* iteration 1 - 10 (the bin counter 2^4 increments to 1)
|
|
* iteration 2 - 30 (the bin counter 2^5 increments to 1)

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

* This function call ensures that hotplug mechanism does not kick-in

* candidacy algo would then reflect the same in dhd->rx_napi_cpu.
