   9        help
  10          DSP/BIOS Bridge is designed for platforms that contain a GPP and
  11          one or more attached DSPs.  The GPP is considered the master or
  12          "host" processor, and the attached DSPs are processing resources
  13          that can be utilized by applications and drivers running on the GPP.
  14
  15          This driver depends on OMAP Mailbox (OMAP_MBOX_FWK).

  17config TIDSPBRIDGE_DVFS
  18        bool "Enable Bridge Dynamic Voltage and Frequency Scaling (DVFS)"
  19        depends on TIDSPBRIDGE && OMAP_PM_SRF && CPU_FREQ
  20        help
  21          DVFS allows DSP Bridge to initiate the operating point change to
  22          scale the chip voltage and frequency in order to match the
  23          performance and power consumption to the current processing
  24          requirements.

  26config TIDSPBRIDGE_MEMPOOL_SIZE
  27        hex "Physical memory pool size (Byte)"
  28        depends on TIDSPBRIDGE
  29        default 0x600000
  30        help
  31          Allocate specified size of memory at booting time to avoid allocation
  32          failure under heavy memory fragmentation after some use time.

  34config TIDSPBRIDGE_RECOVERY
  35        bool "Recovery Support"
  36        depends on TIDSPBRIDGE
  37        default y
  38        help
  39          In case of DSP fatal error, BRIDGE driver will try to
  40          recover itself.

  42config TIDSPBRIDGE_CACHE_LINE_CHECK
  43        bool "Check buffers to be 128 byte aligned"
  44        depends on TIDSPBRIDGE
  45        help
  46          When the DSP processes data, the DSP cache controller loads 128-Byte
  47          chunks (lines) from SDRAM and writes the data back in 128-Byte chunks.
  48          If a DMM buffer does not start and end on a 128-Byte boundary, the data
  49          preceding the start address (SA) from the 128-Byte boundary to the SA
  50          and the data at addresses trailing the end address (EA) from the EA to
  51          the next 128-Byte boundary will be loaded and written back as well.
  52          This can lead to heap corruption. Say Y, to enforce the check for 128
  53          byte alignment, buffers failing this check will be rejected.

  55config TIDSPBRIDGE_NTFY_PWRERR
  56        bool "Notify power errors"
  57        depends on TIDSPBRIDGE
  58        help
  59          Enable notifications to registered clients on the event of power error
  60          trying to suspend bridge driver. Say Y, to signal this event as a fatal
  61          error, this will require a bridge restart to recover.
  62
  63config TIDSPBRIDGE_BACKTRACE
  64        bool "Dump backtraces on fatal errors"
  65        depends on TIDSPBRIDGE
  66        help
  67          Enable useful information to backtrace fatal errors. Say Y if you
  68          want to dump information for testing purposes.
