crypto: hisilicon - Fix build error

2020-04-03T04:37:26Z

When UACCE is m, CRYPTO_DEV_HISI_QM cannot be built-in. But CRYPTO_DEV_HISI_QM is selected by CRYPTO_DEV_HISI_SEC2 and CRYPTO_DEV_HISI_HPRE unconditionally, which may leads this: drivers/crypto/hisilicon/qm.o: In function 'qm_alloc_uacce': drivers/crypto/hisilicon/qm.c:1579: undefined reference to 'uacce_alloc' Add Kconfig dependency to enforce usable configurations.

crypto: hisilicon/sec2 - Add new create qp process

2020-03-20T03:36:50Z

Combine found device and created qp into one operation instead of found device and create qp both are independent operations. when execute multiple tasks, the different threads may find same device at the same time, but the number of queues is insufficient on the device. causing one of threads fail to create a qp. Now fix this, First find device then create qp, if result failure. the current thread will find next device.

crypto: hisilicon/zip - Use hisi_qm_alloc_qps_node() when init ctx

2020-03-20T03:36:50Z

Encapsulate hisi_qm_alloc_qps_node() to new interface to replace find_zip_device(), which will fix the bug of creating QP failure especially in multi-thread scenario. Signed-off-by: Shukun Tan Reviewed-by: Zhou Wang Reviewed-by: Zaibo Xu Signed-off-by: Herbert Xu

crypto: hisilicon/qm - Put device finding logic into QM

2020-03-20T03:36:50Z

Use struct hisi_qm to maintain device list. Meanwhile, add two external interface into qm, merge find proper device and create qp into QP alloc logic, merge release qps into QP free logic.

crypto: hisilicon/sec2 - Add pbuffer mode for SEC driver

2020-03-12T12:00:14Z

In the scenario of SMMU translation, the SEC performance of short messages (<512Bytes) cannot meet our expectations. To avoid this, we reserve the plat buffer (PBUF) memory for small packets when creating TFM.

crypto: hisilicon/sec2 - Add iommu status check

2020-03-12T12:00:14Z

In order to improve performance of small packets (<512Bytes) in SMMU translation scenario, we need to identify the type of IOMMU in the SEC probe to process small packets by a different method.

crypto: hisilicon/sec2 - Add workqueue for SEC driver.

2020-03-12T12:00:14Z

Allocate one workqueue for each QM instead of one for all QMs, we found the throughput of SEC engine can be increased to the hardware limit throughput during testing sec2 performance. so we added this scheme.

crypto: hisilicon - Use one workqueue per qm instead of per qp

2020-03-12T12:00:14Z

Since SEC need not so many workqueues as our test, we just use one workqueue created by the device driver of QM if necessary, which will also reduce CPU waste without any throughput decreasing. Signed-off-by: Shukun Tan Signed-off-by: Zaibo Xu Reviewed-by: Jonathan Cameron Signed-off-by: Herbert Xu
