#define | Srio_osalCreateSem() Osal_srioCreateSem() |
The macro is used by the SRIO driver to create a semaphore for each SRIO socket opened in blocking mode. Semaphores created should *initially* be created with a count of 0 i.e. unavailable. | |
#define | Srio_osalDeleteSem(X) Osal_srioDeleteSem(X) |
The macro is used by the SRIO driver to delete a previously created semaphore. This is called when a SRIO socket opened in blocking mode is being closed. | |
#define | Srio_osalPendSem(X) Osal_srioPendSem(X) |
The macro is used by the SRIO driver to pend on a semaphore This is called when an application tries to receive data on a blocking socket when there is no data available. Since all semaphores are initially created to be unavailable; this will cause the application to block. | |
#define | Srio_osalPostSem(X) Osal_srioPostSem(X) |
The macro is used by the SRIO driver to post the semaphore The driver posts the semaphore once data is received on a specific socket. | |
#define | Srio_osalMalloc(X) Osal_srioMalloc(X) |
The macro is used by the SRIO driver to allocate memory The SRIO driver uses this macro to allocate memory for its internal driver structures. This is invoked during the driver initialization and startup process. | |
#define | Srio_osalFree(X, Y) Osal_srioFree(X, Y) |
The macro is used by the SRIO driver to free a previously allocated block of memory. | |
#define | Srio_osalDataBufferMalloc(X) Osal_srioDataBufferMalloc(X) |
The macro is used by the SRIO driver to allocate memory for the data buffers in Driver Managed Configuration. All data buffers should allocated should be in the global address space. This macro is invoked during the data path. | |

The macro is used by the SRIO driver to indicate that the block of memory has finished being accessed. If the memory block is cached then the application would need to ensure that the contents of the cache are updated immediately to the actual memory. | |
#define | Srio_osalBeginDescriptorAccess Osal_srioBeginDescriptorAccess |
The macro is used by the SRIO driver to indicate that the driver is about to start accessing a descriptor. | |
#define | Srio_osalEndDescriptorAccess Osal_srioEndDescriptorAccess |
