[PATCH 0/4] crypto: hisilicon - various cleanup for QM and SGL

From: Chenghai Huang

Date: Sat Oct 25 2025 - 06:13:37 EST


This patch series addresses several issues in the hisilicon crypto
driver:
Patch 1: ensures proper synchronization when reading eqe/aeqe
values by saving the complete 4-byte values atomically. This
guarantees the valid bit and queue number are read as a consistent
pair that was written by the device.
Patch 2: adds concurrency protection for the err_threshold variable
to prevent race conditions between sysfs operations and hardware
error handling functions.
Patch 3: removes redundant error checks for curr_hw_sgl since
acc_get_sgl() cannot fail after mem_block creation, simplifying the
code.
Patch 4: adds a default case to a switch statement in
qm_vft_data_cfg to comply with coding style and prevent compiler
warnings.
