Add a driver framework for EEA that will be available in the future.
This driver is currently quite minimal, implementing only fundamental
core functionalities. Key features include: I/O queue management via
adminq, basic PCI-layer operations, and essential RX/TX data
communication capabilities. It also supports the creation,
initialization, and management of network devices (netdev). Furthermore,
the ring structures for both I/O queues and adminq have been abstracted
into a simple, unified, and reusable library implementation,
facilitating future extension and maintenance.
v16:
1. follow the advices from @ALOK TIWARI
http://lore.kernel.org/all/5ff95a71-69e5-4cb6-9b2a-5224c9...
v15:
1. remove 'default m' from eea kconfig
2. free the resources when open failed.
v14:
1. some tiny fixes
v13:
1. fix some tiny fixes @Simon
v12:
I encountered some issues with sending the v11 patches, as they were quite
messy. Therefore, I'm resending them as v12.
v11:
1. remove auto clean __free(kfree)
2. some tiny fixes
v10:
1. name the jump labels after the target @Jakub
2. rm __GFP_ZERO from dma_alloc_coherent @Jakub
v9:
1. some fixes for ethtool from http://lore.kernel.org/all/20251027183754.52fe2a2c@kernel...
v8: 1. rename eea_net_tmp to eea_net_init_ctx
2. rm code that allocs memory to destroy queues
3. some other minor changes
v7: 1. remove the irrelative code from ethtool commit
2. build every commits with W12
v6: Split the big one commit to five commits
v5: Thanks for the comments from Kalesh Anakkur Purayil, ALOK TIWARI
v4: Thanks for the comments from Troy Mitchell, Przemek Kitszel, Andrew Lunn, Kalesh Anakkur Purayil
v3: Thanks for the comments from Paolo Abenchi
v2: Thanks for the comments from Simon Horman and Andrew Lunn
v1: Thanks for the comments from Simon Horman and Andrew Lunn
Xuan Zhuo (5):
eea: introduce PCI framework
eea: introduce ring and descriptor structures
eea: probe the netdevice and create adminq
eea: create/destroy rx,tx queues for netdevice open and stop
eea: introduce ethtool support
