v4 -> v5: * Fixed performance problem with sharing a umem between different queues on the same netdev. Sharing the dma_pages array between buffer pool instances was a bad idea. It led to many cross-core snoop traffic messages that degraded performance. The solution: only map the dma mappings once as before, but copy the dma_addr_t to a per buffer pool array so that this sharing dissappears. * Added patch 10 that improves performance with 3% for l2fwd with a simple fix that is now possible, as we pass the buffer pool to the driver. * xp_dma_unmap() did not honor the refcount. Fixed. [Maxim] * Fixed bisectabilty problem in patch 5 [Maxim]
Applied, thanks!
