      ath10k: configure frag desc memory to target for qca99X0 · d9156b5f
      Raja Mani authored
      
      
      Pre qca99X0 chipsets follows the model where dynamically allocate
      memory for frag desc on getting new skb for TX. But, this is not
      going to be the case in qca99X0. It expects frag desc memory to be
      allocated at boot time and let the driver to reuse allocated memory
      after every TX completion. So there won't be any dynamic frag memory
      memory allocation in qca99X0 during data transmission.
      
      qca99X0 hardware doesn't need fragment desc address to be programmed
      in msdu descriptor for every data transaction. It needs to know only
      starting address of fragment descriptor at the time of the boot.
      During data transmission, qca99X0 hardware can retrieve corresponding
      frag addr by adding programmed frag desc base addr + msdu id.
      
      Allocate continuous fragment descriptor memory (same size as number of
      descriptor) at the time of target initialization and configure allocated
      dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.
      
      How this is allocated continuous memory is going to be used is not
      covered in this patch. It just allocates memory and hand over to firmware.
      If we don't do it at init time, qca99X0 will stall when firmware tries
      to do TX.

      New htt event table is added for 10.4 firmware. Following new htt
      events are available only 10.4. adding this to generic htt event

      ath10k: add scan support for 10.4 fw · b2297baa
      Raja Mani authored
      
      
      Existing non 10.4 firmware scan related events and commands are
      matching with 10.4 firmware (except chan info event). Link general
      start scan,stop scan, scan channel list configuration functions
      to 10.4 wmi function table and add a new handler to parse 10.4
      specific chan info event.
      
      10.4 firmware has extra scan completion reason
      WMI_SCAN_REASON_INTERNAL_FAILURE and new scan event
      WMI_SCAN_EVENT_FOREIGN_CHANNEL_EXIT compared to previous firmware
      versions. These things are added in respective enum.

      ath10k: enable vdev and peer related operations for 10.4 fw · 373b48cf
      Raja Mani authored
      
      
      Most of existing vdev and peer related functions (vdev create,
      vdev delete, vdev start, peer create, peer delete, peer flush, etc)
      are reusable for 10.4 firmware. Link those general vdev and peer
      functions to 10.4 wmi function table.
      
      Existing general pktlog enable/disable, dbglog configuration functions
      are reusable for 10.4 and add them also in wmi function table.
      
      Also handle few wmi events (sevice rdy, echo, dbg msg, tbtt offset
      update, dbg print) in ath10k_wmi_10_4_op_rx(). wow event is not
      applicable in 10.4 firmware, have it under not implemented print.

      ath10k: handle 10.4 firmware wmi swba event · 3cec3be3
      Raja Mani authored
      
      
      10.4 firmware swba event payload has space to accommodate upto
      512 client traffic indication info & one p2p noa descriptor.
      It's is not matching with exiting swba event format defined for
      non 10.4 firmware. Non 10.4 firmware swba event format is designed
      to support only upto only 128 client and four p2p notice of absence
      descriptor.
      
      following changes are done in this patch to enable ath10k to handle
      10.4 firmware swba event,
      
       - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba
         event in 10.4 wmi rx handler.
      
       - add 10.4 specific swba event structure wmi_10_4_host_swba_event.
      
       - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse
         10.4 swba event.
      
       - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station
         power save state.

      ath10k: enhance swba event handler to adapt different size tim bitmap · a03fee34
      Raja Mani authored
      
      
      Due to 512 client support in 10.4 firmware, size of tim ie is going
      to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
      what is carried in swba event from 10.4 firmware is bit higher.
      
      The only bottle neck to reuse existing swba handler
      ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
      with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
      This patch removes such size limitation and makes it more suitable
      to handle swba event which has different size tim bitmap.
      
      All existing swba event parsing functions are changed to adapt this
      change. Actual support to handle 10.4 swba event is added in next patch.
      Only preparation is made in this patch.
