Please consider backporting commit 86ad60a65f29dd862a11c22bb4b5be28d6c5cef1 crypto: x86/aes-ni-xts - use direct calls to and 4-way stride to stable. It addresses a rather substantial retpoline-related performance regression in the AES-NI XTS code, which is a widely used disk encryption algorithm

[PATCH v2 2/4] crypto: cavium - Fix the parameter of dma_unmap_sg()

From: Xiang Chen For function dma_unmap_sg(), the parameter should be number of elements in the scatterlist prior to the mapping, not after the mapping. So fix this usage. Signed-off-by: Xiang Chen --- drivers/crypto/cavium/nitrox/nitrox_reqmgr.c | 9 + 1 file changed, 5 insertions(+)

[PATCH v2 0/4] Fix the parameter of dma_map_sg()

From: Xiang Chen According to Documentation/core-api/dma-api-howto.rst, the parameters of dma_unmap_sg() must be the same as those which are passed in to the scatter/gather mapping API. But for some drivers under crypto, the parameter of dma_unmap_sg() is number of elements after mapping. So fix

[PATCH v3 2/2] crypto: ccp - fix command queuing to TEE ring buffer

Multiple threads or clients can submit a command to the TEE ring buffer. This patch helps to synchronize command submission to the ring. One thread shall write a command to a TEE ring buffer entry only if: - Trusted OS has notified that the TEE command for the given entry has been processed a

[PATCH v3 1/2] crypto: ccp - reduce tee command status polling interval from 5ms to 1ms

The PSP TEE device driver polls the command status variable every 5ms to check for command completion. Reduce this time to 1ms so that there is an improvement in driver response time to clients which submit TEE commands. Reviewed-by: Devaraj Rangasamy Signed-off-by: Rijo Thomas --- drivers/cryp

[PATCH v3 0/2] PSP TEE driver update and bug fixes

The first patch helps to improve the response time by reducing the polling time of the tee command status variable. Second patch is a bug fix to handle multi-threaded use-case. During testing, race condition was seen due to missing synchronisation in writes to the TEE ring buffer. This patch helps
