| * iwlwifi: mvm: support bss dynamic alloc/dealloc of queuesLiad Kaufman2016-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "DQA" is shorthand for "dynamic queue allocation". This enables on-demand allocation of queues per RA/TID rather than statically allocating per vif, thus allowing a potential benefit of various factors. Please refer to the DOC section this patch adds to sta.h to see a more in-depth explanation of this feature. There are many things to take into consideration when working in DQA mode, and this patch is only one in a series. Note that default operation mode is non-DQA mode, unless the FW indicates that it supports DQA mode. This patch enables support of DQA for a station connected to an AP, and works in a non-aggregated mode. When a frame for an unused RA/TID arrives at the driver, it isn't TXed immediately, but deferred first until a suitable queue is first allocated for it, and then TXed by a worker that both allocates the queues and TXes deferred traffic. When a STA is removed, its queues goes back into the queue pools for reuse as needed.

| * iwlwifi: pcie: do not pad QoS AMSDUSara Sharon2016-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We insert padding if the MAC header's size is not a multiple of 4 to ensure that the SNAP header is DWORD aligned. When we do so, we let the firmware know by setting a bit in Tx command (TX_CMD_FLG_MH_PAD) which will instruct the firmware to drop those 2 bytes before sending the frame. However, this is not needed for AMSDU as the sub frame header (14B) complements the MAC header (26B) so that the SNAP header is DWORD aligned without adding any pad. Until 9000, the firmware didn't check the TX_CMD_FLG_MH_PAD bit but rather checked the length of the MAC header itself and assumed the entity that enqueued the frame (driver or internal firmware code) added the pad. Since the driver inserted the pad even for AMSDU this logic applied. Note that the padding is a DMA optimization but it's not strictly needed, so we could pad even if it was not needed. However, the CSUM hardware introduced for the 9000 devices requires to not pad AMSDU as it is not needed, and will fail if such a pad exists. Due to older FW not checking the padding bit but checking the mac header size itself - we cannot do this adjustments for older generations. Do not align the size if it is an AMSDU and HW checksum is enabled - which will only happen on 9000 devices and on.

| * iwlwifi: pcie: enable interrupts explicitly on resumeSara Sharon2016-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When entering suspend the driver calls iwl_disable_interrupts() and then iwl_pcie_disable_ict(). On resume the driver calls only iwl_pcie_reset_ict() without calling explicitly to iwl_enable_interrupts(). This mostly works since iwl_pcie_reset_ict is calling to iwl_enable_interrupts, but it doesn't work when there is no ict_table in MSIx mode. The result is that driver tries to resume but fails since it doesn't get the RX interrupt from FW indicating that d0i3 exit was completed. Fix it by adding an explicit call to enable interrupts.

The firmware will collect a defined set of statitics (see the notification for details) that allow to know how busy the medium is. The driver issues a request to the firmware that includes the duration of the measurement (the firmware needs to be on channel for that amount of time) and the timeout (in case the firmware has a lot of offchannel activities). If the timeout elapses, the firmware will send partial results which are still valuable. In case of disassociation / channel switch and alike, the driver is in charge of stopping the measurements and the firmware will reply with partial results. The user space API for now is debugfs only and will be implmemented in an upcoming patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the driver has 2 buffers for paging: 1. paging db - this contains all of the pages that were in the FW image, that the driver stores for the FW. This is allocated for each block separately (not contiguous). 2. download buffer - we need to provide this empty buffer for the iwl_sdio_load_fw_chunk function to copy the requested pages to the shared memory. This is one big buffer of contiguous memory whose size is the size of all the blocks that the fw paging section can contain. This download buffer size is too big, and causes the allocation to fail sometimes. Since the driver allocates memory for each block separately, it is not possible for the FW to request all of the pages in one request (the FW gives an address and size, so blocks need to be contiguous for this to happen), therefore the FW is limited to request only one block. Decrease the size of the paging download buffer to be the size of a paging block.
