crypto: cavium - fix dma_free_coherent() size

2026-02-26T23:00:45+00:00

[ Upstream commit 941676c30ba5b40a01bed92448f457ce62fd1f07 ] The size of the buffer in alloc_command_queues() is curr->size + CPT_NEXT_CHUNK_PTR_SIZE, so used that length for dma_free_coherent().

crypto: cavium/nitrox - add WQ_PERCPU to alloc_workqueue users

2025-11-14T10:15:48+00:00

Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. alloc_workqueue() treats all queues as per-CPU by default, while unbound workqueues must opt-in via WQ_UNBOUND. This default is suboptimal: most workloads benefit from unbound queues, allowing the scheduler to place worker threads where they’re needed and reducing noise when CPUs are isolated. This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default. Suggested-by: Tejun Heo Signed-off-by: Marco Crivellari Signed-off-by: Herbert Xu

crypto: cavium/zip - Remove driver

2025-04-07T05:22:25+00:00

Remove cavium/zip as it is obsolete and stands in the way of acomp API work. If this is ever resurrected, please turn it into an acomp driver. Signed-off-by: Herbert Xu

crypto: cavium - Move cpt and nitrox rules into cavium Makefile

crypto: cavium/zip - drop obsolete 'comp' implementation

The 'comp' API is obsolete and will be removed, so remove this comp implementation. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: scomp - Remove tfm argument from alloc/free_ctx

2025-03-15T08:21:22+00:00

The tfm argument is completely unused and meaningless as the same stream object is identical over all transforms of a given algorithm. Remove it. Signed-off-by: Herbert Xu

crypto: cavium - Fix an error handling path in cpt_ucode_load_fw()

2024-11-15T11:52:51+00:00

If do_cpt_init() fails, a previous dma_alloc_coherent() call needs to be undone. Add the needed dma_free_coherent() before returning. Fixes: 9e2c7d99941d ("crypto: cavium - Add Support for Octeon-tx CPT Engine") Signed-off-by: Christophe JAILLET Signed-off-by: Herbert Xu

crypto: cavium - Fix the if condition to exit loop after timeout

2024-10-28T10:33:11+00:00

The while loop breaks in the first run because of incorrect if condition. It also causes the statements after the if to appear dead. Fix this by changing the condition from if(timeout--) to if(!timeout--). This bug was reported by Coverity Scan. Report: CID 1600859: (#1 of 1): Logically dead code (DEADCODE) dead_error_line: Execution cannot reach this statement: udelay(30UL); Fixes: 9e2c7d99941d ("crypto: cavium - Add Support for Octeon-tx CPT Engine") Signed-off-by: Everest K.C.
