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). + +config TIDSPBRIDGE_DVFS + 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. + +config TIDSPBRIDGE_MEMPOOL_SIZE + hex "Physical memory pool size (Byte)" + depends on TIDSPBRIDGE + default 0x600000 + help + Allocate specified size of memory at booting time to avoid allocation + failure under heavy memory fragmentation after some use time. + +config TIDSPBRIDGE_DEBUG + bool "Debug Support" + depends on TIDSPBRIDGE + help + Say Y to enable Bridge debugging capabilities + +config TIDSPBRIDGE_RECOVERY + bool "Recovery Support" + depends on TIDSPBRIDGE + default y + help + 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.
