2018-01-09qcacmn: Reduce the number of scheduler message buffers for WINVivek
Reduced the number of scheduler message buffers for WIN to 2k from 4k since WIN is only using 2 scheduler queues. Changed the order of two members of scheduler messgae structure to avoid additional padding on 64bit platform. Change-Id: Ic74d60878867c45413bc4fbd5c56feb4dd421699 CRs-Fixed: 2157621
2017-12-15qcacmn: split scheduler init/deinitDustin Brown
A commonly used and robust life-cycle pattern consists of the following 4 steps: 1) create (allocate resources) 2) start (mark resources as safe for use) 3) stop (mark resources as unsafe for use) 4) destroy (deallocate resources) This pattern effectively prevents access to uninitialized and freed resources. While the dispatcher psoc life-cycle follows this pattern, the global life-cycle is condensed into steps 1 and 4. Unsurprisingly, this led to uninitialized and freed resource access problems, especially in regards to the scheduler thread. Split the scheduler init and deinit life-cycle functions into init, enable, disable, and deinit. Create new global enable and disable dispatcher functions, and call the new scheduler APIs as appropriate. This brings the global dispatcher life-cycle in line with the existing psoc life-cycle, and prevents many scheduler related resource access issues.

2017-12-11qcacmn: Refactor Scheduler init/deinit pathsDustin Brown
There are many minor discrepancies in the scheduler module's init and deinit paths. Refactor the scheduler init/deinit code paths to address any discrepancies between the two. Also ensure error path cleanup cleans up all the resources that were previously created. Change-Id: Ib392f41a887031cd710aebaca32eb653952550a4 CRs-Fixed: 2153210
2017-12-11qcacmn: Use sched logging helpers in scheduler_api.cDustin Brown

2017-10-17qcacmn: Use atomic set bit ops for mc threadHouston Hoffman
The basic qdf bit ops are not atomic. Race conditions can lead to messages stuck in queues without mc thread being woken up. Change-Id: I42093b863c7ed93c5c2baf0bd14106eb4fe082fc CRs-Fixed: 2118014

2017-05-26qcacmn: Remove assert in Scheduler thread post message pathDustin Brown
In situations where the scheduler thread has been stopped, but some threads are still trying to post massages to it, a particular assert can be triggered excessively. Remove the post message assert when the scheduler thread is stopped, and instead simply log an error. Change-Id: I5b898dc3ea22bbedcdf2287ef6f3bcee1560bb6b CRs-Fixed: 2046232

2017-05-16qcacmn: Change log levels in scheduler API'sVivek
Changed the log levels from ERROR to DEBUG for few prints in the scheduler API's since the prints were not for errors but for debugging purposes. Change-Id: I2a351de5933cfe6ec7e52d48fbc6e32880854276 CRs-Fixed: 2034873
2017-05-03qcacmn: Change init-deinit sequence of scheduler & call flush callbackKrunal Soni
Provide fix such a way that scheduler's initialization happens at the end after all components' initialization gets done. Same-way scheduler's deinitiazation happens very first before other component's deinit gets started. scheduler also need to call component's provided callback to notify that component while flushing component's message queue.

When the watchdog timer expires, immediately crash the device in debug builds for easier debugging. Change-Id: I4b43a9e12fc1f5b8a795fec790fe7548a100d9db CRs-Fixed: 2037094
2017-04-18qcacmn: Add provision for flush callback in scheduler messageRajeev Kumar
Add provision for flush callback in scheduler message such that during driver unload scheduler can invoke the flush callback and components can release the common object ref count which is taken before posting the message. Change-Id: I28490e18247239af27feef3a4b53e5080ab012fc CRs-Fixed: 2034772

2017-04-17qcacmn: Validate existence of sch thread before posting a messageKrunal Soni
If scheduler thread thread doesn't exist or has been shutdown then don't post a message otherwise it will cause a memory leak. validate the existence of scheduler thread before posting a message. Change-Id: Id0e75bdebc7db8c00d9efb8a6e8678491b21a20f CRs-Fixed: 2031651
2017-03-16qcacmn: Do not allocate scheduler context dynamicallyRajeev Kumar
Scheduler context size is more than 400KB so run time memory allocation may fail when system memory is fragmented. Do not allocate scheduler context memory dynamcially instead allocate it from .bss section. Change-Id: I19ebd0689f81b971bde271e1a540952cf41a6cba CRs-Fixed: 2020711

2017-02-07qcacmn: Initialize qid to qidx mapping to max valueKrunal Soni
By default qid to qidx mapping gets value zero as default initialization which creates issue to identify whether zero is valid or invalid index. Initializing to maximum value will eliminate above mentioned issue. Change-Id: I4c0e2ba45e67fe6e167bd965bdb7ab901c3828a8 CRs-Fixed: 2001133
