      ASoC: dmaengine-pcm: Provide default config · fa654e08
      Lars-Peter Clausen authored
      This patch adds some default settings for the generic dmaengine PCM driver for
      the case that no config has been supplied. The following defaults are used:
      	* Use snd_dmaengine_pcm_prepare_slave_config for preparing the DMA slave
      	  config.
      	* 512kB for the prealloc buffer size. This value has been chosen based on
      	  'feels about right' and is not backed up by any scientific facts. We
      	  may need to come up with something smarter in the future but it should
      	  work fine for now.
      
      With this infrastructure in place we can finally write DAI drivers which are
      independent of the DMA controller they are connected to. This is e.g. useful if
      the DAI IP core is reused across different SoCs, but the SoCs uses different DMA
      controllers.

      ASoC: dmaengine-pcm: Add support for querying DMA capabilities · c0de42bf
      Lars-Peter Clausen authored
      Currently each platform making use the the generic dmaengine PCM driver still
      needs to provide a custom snd_pcm_hardware struct which specifies the
      capabilities of the DMA controller, e.g. the maximum period size that can be
      supported. This patch adds code which uses the newly introduced
      dma_get_slave_caps() API to query this information from the dmaengine driver.
      The new code path will only be taken if the 'pcm_hardware' field of the
      snd_dmaengine_pcm_config struct is NULL.
      
      The patch also introduces a new 'fifo_size' field to the
      snd_dmaengine_dai_dma_data struct which is used to initialize the
      snd_pcm_hardware 'fifo_size' field and needs to be set by the DAI driver.

        And one pain in the ass revert, so we have VGA arbitration that when
        implemented 4-5 years ago really hoped that GPUs could remove
        themselves from arbitration completely once they had a kernel driver.
      
        It seems Intel hw designers decided that was too nice a facility to
        allow us to have so they removed it when they went on-die (so since
        Ironlake at least).  Now Alex Williamson added support for VGA
        arbitration for newer GPUs however this now exposes itself to
        userspace as requireing arbitration of GPU VGA regions and the X
        server gets involved and disables things that it can't handle when VGA
        access is possibly required around every operation.
      
        So in order to not break userspace we just reverted things back to the
        old known broken status so maybe we can try and design out way out.
      
        Ville also had a patch to use stop machine for the two times Intel
        needs to access VGA space, that might be acceptable with some rework,
        but for now myself and Daniel agreed to just go back"
