2023-04-25memif: support dma optionMarvin Liu1-0/+89
Introduce async model into memif by utilizing new DMA API. Original process is broken down to submission stage and completion stage. As multiple submissions may in flight simultaneously, per thread data is no longer safe, now replace thread data into each dma data structure. As slave side already support zero copy mode, DMA option is only added in master side.

2023-03-06memif: autogenerate socket_idsNathan Skrzypczak1-0/+30
This patch adds an API memif_socket_filename_add_del_v2 that allows autogenerating memif socket_id when passing ~0 in the socket_id field. It opportunistically walks the hash to find a free ID to use, and returns it in the reply. socket_filename also becomes a variable length string, to accomodate for longer names (in case a netns gets passed) Type: feature Change-Id: I33fc3e1cf553af27579d6bad8691b22b530531cc Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

Getting an unexpected EPOLLOUT for RX queue and crashing due to missing callback function on write_function to handle EPOLLOUT.

It is likely that the EPOLLOUT is meant for the previous owner of the same file descriptor number which memif recycled and memif RX did not expect to receive an EPOLLOUT. For defensive play, we create a dummy callback function to ignore the EPOLLOUT instead of crashing.

2018-03-22memif: version 2Damjan Marion1-6/+33
In version 1 of the protocol sender was always ring producer and receiver was consumer. In version 2 slave is always producer, and in case of master-to-slave rings, slave is responsible for populating ring with empty buffers. As this is major change, we need to bump version number. In addition, descriptor size is reduced to 16 bytes. This change allows zero-copy-slave operation (to be privided in the separate patch).
