net: cnic: Convert tasklet API to new bottom half workqueue mechanism

2024-08-01T01:59:46Z

Migrate tasklet APIs to the new bottom half workqueue mechanism. It replaces all occurrences of tasklet usage with the appropriate workqueue APIs throughout the cnic driver. This transition ensures compatibility with the latest design and enhances performance.

cnic,bnx2,bnx2x: use UIO_MEM_DMA_COHERENT

2024-03-07T21:52:59Z

Use the UIO_MEM_DMA_COHERENT type to properly handle mmap for dma_alloc_coherent buffers. The cnic l2_ring and l2_buf mmaps have caused page refcount issues as the dma_alloc_coherent no longer provide __GFP_COMP allocation as per commit "dma-mapping: reject __GFP_COMP in dma_alloc_attrs". Fix this by having the uio device use dma_mmap_coherent. The bnx2 and bnx2x status block allocations are also dma_alloc_coherent, and should use dma_mmap_coherent. They don't allocate multiple pages, but this interface does not work correctly with an iommu enabled unless dma_mmap_coherent is used.

cnic: Add a signature to indicate valid doorbell offset.

2014-01-02T03:08:08Z

The buffer that is used to pass doorbell offset to the userspace UIO driver may contain nonzero value in older versions of bnx2x driver. Userspace cannot easily tell whether it contains a valid doorbell offset or not. With the added signature, userspace will only use the doorbell offset if the signature is present. Update version to 2.5.19. Signed-off-by: Eddie Wai Signed-off-by: Michael Chan Signed-off-by: David S. Miller
