description: |
|
||
|
|
Command DB is a database that provides a mapping between resource key and the
|
||
|
|
resource address for a system resource managed by a remote processor. The data
|
||
|
|
is stored in a shared memory region and is loaded by the remote processor.
|
||
|
|
|
||
|
|
Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for
|
||
|
|
controlling shared resources. Depending on the board configuration the shared
|
||
|
|
resource properties may change. These properties are dynamically probed by the
|
||
|
|
remote processor and made available in the shared memory.
