      ASoC: Intel: Work around to fix HW D3 potential crash issue · 0d2135ec
      Jie Yang authored
      When using clock gatings to save power, there are some known issues:
      1. core clock gating (DCLCGE) must be disabled during D0 and D3 entry
      and updating SRAM banks (VDRTCTL0).
      2. DSP trunk clock gating (DTCGE) can cause FW crashes, disable it in D0.
      
      To align with the new W/A flow from FW team, we must set VDRTCTL0.D3PGD
      to 1 (D3 power gating disabled) at first startup and keep it all the time.
      ADSP will be in D0 on first boot by BIOS part of WA. Required delays must
      be preserved (waiting for HW to stabilize, after enabling CCG, changing
      SRAM PG, D3PG).
      
      D3->D0:
      1. Disable core clock gating (VDRTCTL2.DCLCGE = 0)
      2. Enable other CG apart from DTCG and DCLCG (VDRTCTL2. DCLCGE and DTCGE = 0)
      3. Disable D3PG (VDRTCTL0.D3PGD = 1)
      4. Power up necessary SRAM and wait at least for 18 clock cycles for every
      bank you have powered up
      5. Set D0 state(PMCS.PS = 0), wait for HW
      6. Restore MCLK (clkctl.smos, disabled in D3 entry point 4)
      7. Stall and reset core, set CSR
      8. Enable core clock gating (VDRTCTL2.DCLCGE = 1), delay 50 us
      9. Unreset core
      10.Load FW, configure PLL and other necessary things
      11.Unstall core
      
      Changing SRAM PG during D0:
      1. Disable core clock gating (VDRTCTL2.DCLCGE = 0)
      2. Set PG mask
      3. Wait at least for 18 clock cycles for every bank you have powered up
      4. Enable core clock gating, delay 50 us
      
      D0->D3:
      1. Disable core clock gating (DCLCGE = 0)
      2. Stall and reset core
      3. Power down entire SRAM and wait at least for 18 clock cycles for every bank
      (Enable SRAM PG (ISRAMPGE = 0x3FF, DSRAMPGE = 0xFFFFF, D3SRAMPGD = 0), remember
      about preserving VDRTCTL0.D3PGD = 1)
      4. Shutdown PLL, disable MCLK(clkctl.smos = 0), Enable DTCG to save power
      5. Set D3 state(PMCS.PS = 3), delay 50 us
      6. Enable core clock gating, delay 50 us

      ASoC: Intel: Fix block is enabled multiple times issue · 35c0a8c0
      Jie Yang authored
      During FW parsing and loading, block_list_prepare() may
      be called for each raw data block copying and this may
      made the hsw_block_enable() called mutiple times, which
      increase block->users many times. The result of this is
      hsw_block_disable() can't power gated the related block
      when trying to free the blocks during suspend, and the
      power gating status also confused.
      
      Here check the block user status, only calling enable()
      for those blocks who has no user yet. Remember that
      this works correctlly on current case, where there are
      enough SRAM memory so different module won't share a
      memory block. For further usage, we may need restructure
      the struct sst_mem_block to save the module list who is
      using it.

      ASoC: Intel: Make ADSP memory block allocation more generic · e9600bc1
      Liam Girdwood authored
      Current block allocation is tied to block type and requestor type. Make the
      allocation more generic by removing the struct module parameter and adding
      a generic block allocator structure. Also pass in the list that the blocks
      have to be added too in order to remove dependence on block requestor type.
      
      ASoC: Intel: update scratch allocator to use generic block allocator
      
      Update the scratch allocator to use the generic block allocator and calculate
      total scratch buffer size.
      
      ASoC: Intel: Add call to calculate offsets internally within the DSP.
      
      A call to calculate internal DSP memory addresses used to allocate persistent
      and scartch buffers.
      
      ASoC: Intel: Add runtime module support.
      
      Add support for runtime module objects that can be created for every FW
      module that is parsed from the FW file. This gives a 1:N mapping between
      the FW module from file and the runtime instantiations of that module.
      
      We also need to make sure we remove every module and runtime module when
      we unload the FW.
      
      ASoC: Intel: Add DMA firmware loading support
      
      Add support for DMA to load firmware modules to the DSP memory blocks.
      Two DMA engines are supported, DesignWare and Intel MID.
      
      ASoC: Intel: Add runtime module lookup API call
      
      Add an API to allow quick lookup of runtime modules based on ID.
      
      ASoC: Intel: Provide streams with dynamic module information
      
      Remove the hard coded module paramaters and provide each module with
      dynamically generated buffer information for scratch and persistent
      buffers.
