soc/fsl/qbman: Use for_each_online_cpu() instead of for_each_cpu()

2025-09-22T19:31:08Z

Replace the opencoded for_each_cpu(cpu, cpu_online_mask) loop with the more readable and equivalent for_each_online_cpu(cpu) macro. Signed-off-by: Fushuai Wang Link: https://lore.kernel.org/r/20250811065216.3320-1-wangfushuai@baidu.com Signed-off-by: Christophe Leroy

soc: fsl: qbman: Remove const from portal->cgrs allocation type

2025-05-12T23:38:56Z

In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct qman_cgrs *", but the returned type, while technically matching, is const qualified. As there is no general way to remove const qualifiers, adjust the allocation type to match the assignment.

soc/qman: test: Use kthread_run_on_cpu()

2025-01-02T21:12:12Z

Use the proper API instead of open coding it. However it looks like kthreads here could be replaced by the use of a per-cpu workqueue instead. Signed-off-by: Frederic Weisbecker

soc: fsl: qbman: Remove redundant warnings

2024-09-03T05:50:57Z

This warning was added by commit 07f86917a450 ("soc/fsl/qbman: Use shared-dma-pool for QMan private memory allocations") but RESERVEDMEM_OF_DECLARE usage was removed by commit 3e62273ac63a ("soc: fsl: qbman: Remove RESERVEDMEM_OF_DECLARE usage") . For non-popwerpc platforms, such as ls1043, this warning is redundant. ls1043 itself uses shared-dma-mem.

soc: fsl: qbman: Use raw spinlock for cgr_lock

2024-03-13T08:12:02Z

smp_call_function always runs its callback in hard IRQ context, even on PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock for cgr_lock to ensure we aren't waiting on a sleeping task. Although this bug has existed for a while, it was not apparent until commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change") which invokes smp_call_function_single via qman_update_cgr_safe every time a link goes up or down.
