| tristate "DSP Bridge driver" |
| depends on ARCH_OMAP3 && !ARCH_MULTIPLATFORM && BROKEN |
| select MAILBOX |
| select OMAP2PLUS_MBOX |
| 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). |
| |
| config TIDSPBRIDGE_DVFS |
| bool "Enable Bridge Dynamic Voltage and Frequency Scaling (DVFS)" |
| depends on TIDSPBRIDGE && 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_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. Say Y, to enforce the check for 128 |
| byte alignment, buffers failing this check will be rejected. |
| |
| config TIDSPBRIDGE_NTFY_PWRERR |
| bool "Notify power errors" |
| depends on TIDSPBRIDGE |
| help |
| Enable notifications to registered clients on the event of power error |
| trying to suspend bridge driver. Say Y, to signal this event as a fatal |
| error, this will require a bridge restart to recover. |
| |
| config TIDSPBRIDGE_BACKTRACE |
| bool "Dump backtraces on fatal errors" |
| depends on TIDSPBRIDGE |
| help |
| Enable useful information to backtrace fatal errors. Say Y if you |
| want to dump information for testing purposes. |
