  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).

  17 config 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.

  30         help
  31           Allocate specified size of memory at booting time to avoid allocation
  32           failure under heavy memory fragmentation after some use time.

  38           Say Y to enable Bridge debugging capabilities

  44         help
  45           In case of DSP fatal error, BRIDGE driver will try to
  46           recover itself.

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

  64         help
  65           WTD3 is managed by DSP and once it is enabled, DSP side bridge is in
  66           charge of refreshing the timer before overflow, if the DSP hangs MPU
  67           will caught the interrupt and try to recover DSP.

  81           Enable notifications to registered clients on the event of power errror
  82           trying to suspend bridge driver. Say Y, to signal this event as a fatal
  83           error, this will require a bridge restart to recover.
  84
  85 config TIDSPBRIDGE_BACKTRACE
  86         bool "Dump backtraces on fatal errors"

  89           Enable useful information to backtrace fatal errors. Say Y if you
  90           want to dump information for testing purposes.
