[PATCH v4 00/11] crypto: hisilicon - add fallback function for hisilicon accelerater driver

[Chenghai Huang]

1.Supports multiple tfms sharing the same device queue to avoid tfm
creation failure.
2.Support fallback for zip/sec2/hpre when queue allocation fails or
when processing unsupported specifications.

When pf_q_num is less than the number of tfms, queues will be
obtained from devices with fewer references and closer NUMA
distances(priority: ref counts -> NUMA distances).

We can test by zswap:
modprobe hisi_zip uacce_mode=1 pf_q_num=2
cat /sys/class/uacce/hisi_zip-?/available_instances
echo hisi-deflate-acomp > /sys/module/zswap/parameters/compressor

V3: https://lore.kernel.org/all/20251122074916.2793717-1-huangchenghai2@xxxxxxxxxx/
Updates:
- In patch 7, fix the issue of skipping qp enablement due to incorrect
  reference count judgment.
- In patch 6, Supplement the device power wake-up operation before
  applying for the qp.

V2: https://lore.kernel.org/all/20250818065714.1916898-1-huangchenghai2@xxxxxxxxxx/
Updates:
- According to crypto framework, support shared queues to address
  the hardware resource limitation on tfm.
- Remove the fallback modification for x25519.

V1: https://lore.kernel.org/all/20250809070829.47204-1-huangchenghai2@xxxxxxxxxx/
Updates:
- Remove unnecessary callback completions.
- Add CRYPTO_ALG_NEED_FALLBACK to hisi_zip's cra_flags.

Chenghai Huang (8):
  crypto: hisilicon/zip - adjust the way to obtain the req in the
    callback function
  crypto: hisilicon/sec - move backlog management to qp and store sqe in
    qp for callback
  crypto: hisilicon/qm - enhance the configuration of req_type in queue
    attributes
  crypto: hisilicon/qm - centralize the sending locks of each module
    into qm
  crypto: hisilicon - consolidate qp creation and start in
    hisi_qm_alloc_qps_node
  crypto: hisilicon/qm - add reference counting to queues for tfm kernel
    reuse
  crypto: hisilicon/qm - optimize device selection priority based on
    queue ref count and NUMA distance
  crypto: hisilicon/zip - support fallback for zip

Qi Tao (1):
  crypto: hisilicon/sec2 - support skcipher/aead fallback for hardware
    queue unavailable

Weili Qian (1):
  crypto: hisilicon/hpre - support the hpre algorithm fallback
