由 Herbert Xu 提交于
Although the existing hash walk interface has already been used by a number of ahash crypto drivers, it turns out that none of them were really asynchronous. They were all essentially polling for completion. That's why nobody has noticed until now that the walk interface couldn't work with a real asynchronous driver since the memory is mapped using kmap_atomic. As we now have a use-case for a real ahash implementation on x86, this patch creates a minimal ahash walk interface. Basically it just calls kmap instead of kmap_atomic and does away with the crypto_yield call. Real ahash crypto drivers don't need to yield since by definition they won't be hogging the CPU.

This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. The NULL assignment to np->units is removed as there is no interaction between this field and sun4v_hvapi_unregister. Also, the labels out_free_units and out_free are removed as they are no longer required. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: NHimangi Saraogi <himangi774@gmail.com> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Currently, the driver enqueues a request only if the busy bit is false. And every request initiates a dequeue. If 2 requests arrive simultaneously, only one of them will be dequeued. To avoid this senario, we will enqueue the next request irrespective of the system condition (that is what queue is here for). Also schedule at a tasklet immediatly after the current request is done. The tasklet will dequeue the next request in the queue, giving continuous loop. tasklet will exit if there are no requests in the queue.
