|
|
* The startup sequence is
|
|
*
|
|
* 1: dlopen driver
|
|
* 2: Query driver version with rsdHalQueryVersion() and verify
|
|
* that the driver (e.g., libRSDriver) is compatible with the shell
|
|
* (i.e., libRS_internal) responsible for loading the driver
|
|
* 3: Fill in HAL pointer table with calls to rsdHalQueryHAL()
|
|
* 4: Initialize the context with rsdHalInit()
|
|
*
|
|
* If any of these functions return false, the loading of the
|
|
* driver will abort and the reference driver will be used.
|
|
* rsdHalAbort() will be called to clean up any partially
|
|
* allocated state.
|
|
*
|
|
* A driver should return FALSE for any conditions that will
|
|
* prevent the driver from working normally.
|
|
*
|
|
*
|
|
* If these are successful, the driver will be loaded and used
|
|
* normally. Teardown will use the normal
|
|
* context->mHal.funcs.shutdown() path. There will be no call
|
|
* to rsdHalAbort().
