Enable ibmveth for Cooperative Memory Overcommitment (CMO). For this driver it means calculating a desired amount of IO memory based on the current MTU and updating this value with the bus when MTU changes occur. Because DMA mappings can fail, we have added a bounce buffer for temporary cases where the driver can not map IO memory for the buffer pool. The following changes are made to enable the driver for CMO: * DMA mapping errors will not result in error messages if entitlement has been exceeded and resources were not available. * DMA mapping errors are handled gracefully, ibmveth_replenish_buffer_pool() is corrected to check the return from dma_map_single and fail gracefully. * The driver will have a get_desired_dma function defined to function in a CMO environment. * When the MTU is changed, the driver will update the device IO entitlement Signed-off-by: Robert Jennings <rcj@linux.vnet.ibm.com> Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Santiago Leon <santil@us.ibm.com> Acked-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> |
