Subject: [PATCH 0/3] wifi: ath11k: fix dest ring-buffer corruption
Date: Mon, 26 May 2025 13:48:00 +0200 [thread overview]
Message-ID: <20250526114803.2122-1-johan+linaro@kernel.org> (raw)
As a follow up to commits:
6d037a372f81 ("wifi: ath11k: fix ring-buffer corruption")
ab52e3e44fe9 ("wifi: ath11k: fix rx completion meta data corruption")
add the remaining missing memory barriers to make sure that destination
ring descriptors are read after the head pointers to avoid using stale
data on weakly ordered architectures like aarch64.
Also switch back to plain accesses for the descriptor fields which is
sufficient after the memory barrier.
