* qcacmn: Remove EXPORT_SYMBOL to avoid duplicate symbol errorKai Liu2017-03-20
| | | | | | | | | MDM platform supports two wlan cards, so two drivers will be loaded at same time. If export these routine, then loading the second driver will encounter duplicate symbol error. Change-Id: Ia2b900011e0a9f693fa28f2774a158e5f5b4291f CRs-Fixed: 2018377

* qcacmn: Add a flag in skb->cb for packet trackingPoddar, Siddarth2017-03-19
| | | | | | | | | | | | | | | | | | | | | | | | When a packet is generated internally, host adds a debug node entry to the table and deletes the entry once received tx completion for that packet by calling qdf_nbuf_free. But when a packet is coming from network stack, host doesn’t add any debug entry to the table and on receiving tx completion, it calls qdf_nbuf_tx_free which will simply free the skb. In case of P2P GO mode where packets are forwarded internally, host creates a private copy of skb and add debug node entry in the table. But when receiving a tx completion for the same packet host calls qdf_nbuf_tx_free which will free the skb but will not remove this node entry from the table. Currently, this api is common for all data tx completion packets. Add an extra flag in control block to differentiate whether skb is generated by driver or come from network stack. If flag is true, that means generated internally and need to remove the entry from debug node table. Change-Id: I61a76fdfedf0429e1b972824dc4513065d53033f CRs-Fixed: 2020947

* qcacmn: Remove event report when failed to allocate memoryZhang Qian2017-03-13
| | | | | | | | | | | | | qcacld-2.0 to qcacld-3.0 propagation There will be recursive call for vos_mem_malloc once there is memory allocation failure, because vos_mem_malloc is called to allocate message buffer for WIFI_EVENT_MEMORY_FAILURE.

* qcacmn: Do IPA version based DMA coherent mask settingHimanshu Agarwal2017-02-14
| | | | | | | | | | | | | | In case of IPA hw version less than 3.0, only 32 bit DMA address can be handled as it is only 32 bit compliant. Because of this, setting DMA coherent mask of 37 when IPA hw version is less than 3.0, crash is happening. Do IPA version based DMA coherent mask setting such that when IPA hw version is less than 3.0, set DMA coherent mask as 32 only.

* qcacmn: Change semantics of Runtime Lock APIsPrashanth Bhatta2017-01-30
| | | | | | | | | | | | | | | Runtime PM lock init API right now returns pointer to a context but this would cause confusion to the caller if feature is not defined and dummy function return NULL as caller can't find real failure versus dummy function returning because feature not being enabled. Fix declaring a data structure in QDF layer that caller can use but it hides the internal details of HIF implementation for Runtime PM locks.

| | | | | | | | | | | | Change the static allocation of tso common info to dynamic allocation to use this structure later on. Introduce one more element in tso common info structure use to store the dma address of EIT header which can be repeatedly use to assign to the dma address of the 0th fragment of all the tso segments corresponding to one jumbo skb.

* qcacmn: Add QDF memory statsMahesh Kumar Kalikot Veetil2017-01-06
| | | | | | | | | | | | | | | | | | | | | | Create debug file system entries to show current QDF memory usage. The 'list' option adds a little overhead, which is minimized by locking node by node while traversing the entire allocated memory list. Major operation is lock-less, using node reference count. Following debugfs entries are added, 1. /sys/kernel/debug/<module_name>_qdf/mem/list This lists QDF allocation by file and line number. It takes some time to traverse the entire allocated list. 2. /sys/kernel/debug/<module_name>_qdf/mem/kmalloc This file shows total kmalloc done by qdf_mem_alloc(). 3. /sys/kernel/debug/<module_name>_qdf/mem/dma This file shows total allocation done by qdf_mem_alloc_consistent() Change-Id: Ie40a7cb6ee03dd58aebd0fbda0118ab06b64725a CRs-Fixed: 1084097
* qcacmn: Add debugfs supportMahesh Kumar Kalikot Veetil2017-01-06
| | | | | | | | | | | | | | | | | | | | Create a root directory for debugfs at /sys/kernel/debug/KBUILD_MODNAME_qdf/. The module name, KBUILD_MODNAME, is used in the path to avoid conflict in case of multiple instances of the same driver. Any sub module in QDF can use this as the root directory to add further files of directories. While unloading the driver the exit routine does a recursive cleanup of any remaining files or sub directories. Even though debugfs is a Linux specific feature, a logic which is related to file system for debugging can be added here. This feature is protected with a compilation flag WLAN_DEBUGFS.

| | | | | | | | | | qdf_trace prototype needs to be defined as well. note: i_qdf_trace.h is still needed for qdf_print to be used, but we have removed dependencies of i_qdf_trace.h on other include files (so this is fine). Change-Id: I01052d00c1619e4847de702a687554badd47882f CRs-Fixed: 1100505
* qcacmn: Change HDD IPA to comply with the refactored SKB CBYun Park2016-12-23
| | | | | | | | | | | | This change refactors IPA private data stored in skb control block, which size is reduced to 32 bits. Owner id is changed to 1 bit, to flag if the owner is IPA. Callback function pointer is removed by adding the callback into cdf. Skb control block priv data is reduced to 16 bits by storing the index to the Tx descriptor list added in HDD.

* qcacmn: IPA uC: Round down Tx/Rx buffer count to nearest power of twoYun Park2016-12-05
| | | | | | | | | | | | | | qcacld-2.0 to qcacmn propagation In certain situation, allocated Tx buffer count could be an arbitrary number, so not power of two. This could violate F/W ring buffer count requirement. If allocated Tx buffer count is not power of two, round down it to the nearest power of two. The same change is also applicable for INI parameters IpaUcTxBufCount and IpaUcRxIndRingCount. Change-Id: I7c119886a669c79adbc7bd9b2c1c1d93de41cf72 CRs-Fixed: 973723

Note that there are allready error level logs in HDD to indicate that a timeout occured. The value add here is that this timeout is noted in the contect of DPTRACE where prior successfull packets will also have been logged.
