tristate "DSP Bridge driver"

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

|
|
bool "Enable Bridge Dynamic Voltage and Frequency Scaling (DVFS)"
|
|
depends on TIDSPBRIDGE && OMAP_PM_SRF && CPU_FREQ
|
|
help
|
|
DVFS allows DSP Bridge to initiate the operating point change to
|
|
scale the chip voltage and frequency in order to match the
|
|
performance and power consumption to the current processing
|
|
requirements.

In case of DSP fatal error, BRIDGE driver will try to
|
|
recover itself.

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

config TIDSPBRIDGE_WDT3

bool "Enable watchdog timer"

depends on TIDSPBRIDGE
|

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

help
|
|
Enable notifications to registered clients on the event of power errror
|
|
trying to suspend bridge driver. Say Y, to signal this event as a fatal
|

error, this will require a bridge restart to recover.

Enable useful information to backtrace fatal errors. Say Y if you
|

want to dump information for testing purposes.
