charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+infradead-linux-arm-kernel=archiver.kernel.org@lists.infradead.org Hello The sun8i-ce hardware can work on multiple requests in one batch. For this it use a task descriptor, and chain them. For the moment, the driver does not use this mechanism and do requests one at a time and issue an irq for each. Using the chaning will permit to issue less interrupts, and increase thoughput. But the crypto/engine can enqueue lots of requests but can ran them only one by one. This serie introduce a way to batch requests in crypto/engine by - setting a batch limit (1 by default) - refactor the prepare/unprepare code to permit to have x requests prepared/unprepared at the same time. For testing the serie, the selftest are not enough, since it issue request one at a time. I have used LUKS for testing it. Please give me what you think about this serie, specially maintainers which have hardware with the same kind of capability.
