This patch includes a missing dependency (CRYPTO_AES) which may lead to an "undefined reference to `aes_expandkey'" linking error. Fixes: 5106dfea ("crypto: qat - add AES-XTS support for QAT GEN4 devices") Reported-by:

Add an hook to initialize the vector routing table with the default values before MSIx is enabled. The new function set_msix_rttable() is called only if present in the struct adf_hw_device_data of the device. This is to allow for QAT devices that do not support that functionality. Signed-off-by:

Introduce support for devices that require multiple firmware images. If a device requires more than a firmware image to operate, load the image to the appropriate Acceleration Engine (AE). Signed-off-by:

Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

Add support for shared ustore mode support. This is required by the next generation of QAT devices to share the same fw image across engines. Signed-off-by:

Introduce new API, qat_uclo_set_cfg_ae_mask(), to allow the load of the firmware image to a subset of Acceleration Engines (AEs). This is required by the next generation of QAT devices to be able to load different firmware images to the device. Signed-off-by:

Add firmware control unit (FCU) CSRs to chip info so the firmware authentication code is common between all devices. Signed-off-by:

Add support for CSS3K, which uses RSA3K as image signature algorithm, to support the next generation of QAT devices. Signed-off-by:
-
Jack Xu authored
Use ae_mask to decide which Accelerator Engine (AE) to target in AE related operations, instead of a sequential loop, to skip AEs that are fused out. Signed-off-by:

Add null pointer check when freeing the memory for firmware. Signed-off-by:

Add misc control CSR to chip info since the CSR offset will be different in the next generation of QAT devices. Signed-off-by:

Add the wake up event to chip info since this value will be different in the next generation of QAT devices. Signed-off-by:

Add reset CSR offset and mask to chip info since they are different in new QAT devices. This also simplifies the reset/clrReset functions by using the reset mask. Signed-off-by:

Add support for local memory lm2 and lm3 which is introduced in the next generation of QAT devices. Signed-off-by:

Introduce the next neighbor (NN) capability in chip_info as NN registers are not supported in certain SKUs of QAT. Signed-off-by:

Modify condition in qat_uclo_wr_mimage() to use a capability of the device (sram_visible), rather than the device ID, so the check is not specific to devices of the same type. Signed-off-by:

Introduce the chip info structure which contains device specific information. The initialization path has been split between common and hardware specific in order to facilitate the introduction of the next generation hardware. Signed-off-by:

Refactor qat_uclo_set_ae_mode() by moving the logic that sets the AE modes to a separate function, qat_hal_set_modes(). Signed-off-by:

Move the definition of ICP_QAT_AE_OFFSET, ICP_QAT_CAP_OFFSET, LOCAL_TO_XFER_REG_OFFSET and ICP_QAT_EP_OFFSET from qat_hal.c to icp_qat_hal.h to avoid the definition of generation specific constants in qat_hal.c. Signed-off-by:

Include the offset of GLOBAL_CSR directly into the enum hal_global_csr and remove the macros SET_GLB_CSR/GET_GLB_CSR to simplify the global CSR access. Signed-off-by:

Change the API and the behaviour of the qat_hal_start() function. With this change, the function starts under the hood all acceleration engines (AEs) and there is no longer need to call it for each engine. Signed-off-by:

Change micro word data mask since the Acceleration Engine (AE) instruction codes have been changed in the new generation QAT devices. Signed-off-by:

Change type for ctx_mask from unsigned char to unsigned long to avoid type casting. Signed-off-by:

Improve the way micro instructions (FW code) are uploaded to Accelerator Engines (AEs). If code starts at PC zero (absolute addressing), read uwords with no relative address. Otherwise, use relative addressing to the page region. Signed-off-by:

Do not mask the AE number with the AE mask when accessing the AE local CSRs. Bit 12 of the local CSR address is the start of AE number so just take out the AE mask here. Signed-off-by:

The return value of qat_hal_rd_ae_csr() is always a CSR value and never a status and should not be stored in the status variable of qat_hal_put_rel_rd_xfer(). This removes the assignment as qat_hal_rd_ae_csr() is not expected to fail. A more comprehensive handling of the theoretical corner case which could result in a fail will be submitted in a separate patch.
