+ @input: pHcd - the host controller definition structure.

+

+
+ @notes: Host controller drivers must call into this function to validate various command

+ The CheckMode option determines the type of validation to perform.
+ if (CheckMode == SDHCD_CHECK_DATA_TRANS_OK) :
+ The host controller must check the card response to determine whether it
+ is safe to perform a data transfer. This API only checks commands that
+ involve data transfers and checks various status fields in the command response.
+ If the card cannot accept data, this function will return a non-successful status that
+ should be treated as a request failure. The host driver should complete the request with the
+ returned status. Host controller should only call this function in preparation for a
+ data transfer.
+ if (CheckMode == SDHCD_CHECK_SPI_TOKEN) :
+ This API checks the SPI token and returns a timeout status if the illegal command bit is
+ set. This simulates the behavior of SD 1/4 bit operation where illegal commands result in
+ a command timeout. A driver that supports SPI mode should pass every response to this
+ function to determine the appropriate error status to complete the request with. If the
+ API returns success, the response indicates that the card accepted the command.
+
+ @example: Checking the response before starting the data transfer :
+ if (SDIO_SUCCESS(status) && (pReq->Flags & SDREQ_FLAGS_DATA_TRANS)) {
+ // check the response to see if we should continue with data
+ status = SDIO_CheckResponse(pHcd, pReq, SDHCD_CHECK_DATA_TRANS_OK);

+ @function: Create an OS-specific helper task/thread
+
+ @function name: SDLIB_OSCreateHelper
+ @prototype: SDIO_STATUS SDLIB_OSCreateHelper(POSKERNEL_HELPER pHelper,
+ PHELPER_FUNCTION pFunction,
+ PVOID pContext)
+ @category: Support_Reference
+
+ @input: pHelper - caller allocated helper object
+ @input: pFunction - helper function
+ @input: pContext - helper context
+
+ @return: SDIO_STATUS
+
+ @notes: This function creates a helper task/thread that runs in a new execution context. The newly
+ created task/thread invokes the helper function. The thread/task exits when the helper
+ function returns. The helper function has the prototype of:
+ THREAD_RETURN HelperFunction(POSKERNEL_HELPER pHelper)
+ The helper function usually implements a while loop and suspends execution using
+ SD_WAIT_FOR_WAKEUP(). On exit the helper function can return an OS-specific THREAD_RETURN
+ code (usually zero). The helper function executes in a fully schedule-able context and
+ can block on semaphores and sleep.
+
+ @see also: SDLIB_OSDeleteHelper , SD_WAIT_FOR_WAKEUP
+
+ @example: A thread helper function:
+ THREAD_RETURN HelperFunction(POSKERNEL_HELPER pHelper)
+ {
+ SDIO_STATUS status;
+ PMYCONTEXT pContext = (PMYCONTEXT)SD_GET_OS_HELPER_CONTEXT(pHelper);
+ // wait for wake up
+ while(1) {
+ status = SD_WAIT_FOR_WAKEUP(pHelper);
+ if (!SDIO_SUCCESS(status)) {
+ break;
+ }
+ if (SD_IS_HELPER_SHUTTING_DOWN(pHelper)) {
+ //... shutting down
+ break;
+ }
+ // handle wakeup...
+ }
+ return 0;
+ }
+
+ @example: Creating a helper:
+ status = SDLIB_OSCreateHelper(&pInstance->OSHelper,HelperFunction,pInstance);
+ if (!SDIO_SUCCESS(status)) {
+ // failed
+ }
+
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++*/
+
+/**++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ @function: Delete an OS helper task/thread
+
+ @function name: SDLIB_OSDeleteHelper
+ @prototype: void SDLIB_OSDeleteHelper(POSKERNEL_HELPER pHelper)
+ @category: Support_Reference
+
+ @input: pHelper - caller allocated helper object
+
+ @notes: This function wakes the helper and waits(blocks) until the helper exits. The caller can
+ only pass an OS helper structure that was initialized sucessfully by
+ SDLIB_OSCreateHelper. The caller must be in a schedulable context.
+
+ @see also: SDLIB_OSCreateHelper
+
+ @example: Deleting a helper:
+ if (pInstance->HelperCreated) {
+ // clean up the helper if we successfully created it
+ SDLIB_OSDeleteHelper(&pInstance->OSHelper);
+ }
