2021-12-24crypto: qat - support the reset of ring pairs on PFMarco Chiappero
Add support for triggering a HW reset of a specific ring pair. Being a device specific feature, add it to the hw_device_data struct. This feature is supported only by QAT GEN4 devices. This patch is based on earlier work done by Zelin Deng.

The new interrupt event will disrupt the current normal processing flow and cause other problems. Therefore, the operation of writing the QM_DOORBELL_CMD_AEQ doorbell register needs to be placed after all interrupt events processing are completed.

2021-12-17crypto: ccp - Add SEV_INIT_EX supportDavid Rientjes
Add new module parameter to allow users to use SEV_INIT_EX instead of SEV_INIT. This helps users who lock their SPI bus to use the PSP for SEV functionality. The 'init_ex_path' parameter defaults to NULL which means the kernel will use SEV_INIT, if a path is specified SEV_INIT_EX will be used with the data found at the path. On certain PSP commands this file is written to as the PSP updates the NV memory region. Depending on file system initialization this file open may fail during module init but the CCP driver for SEV already has sufficient retries for platform initialization. During normal operation of PSP system and SEV commands if the PSP has not been initialized it is at run time. If the file at 'init_ex_path' does not exist the PSP will not be initialized. The user must create the file prior to use with 32Kb of 0xFFs per spec.

Extra crypto manager auto test were crashing or failling due to 2 reasons: - block in a dead loop (dues to issues in cipher end process management) - crash due to read/write unmapped memory (this crash was also reported when using openssl afalg engine) Rework interrupt management, interrupts are masked as soon as they are no more used: if input buffer is fully consumed, "Input FIFO not full" interrupt is masked and if output buffer is full, "Output FIFO not empty" interrupt is masked. And crypto request finish when input *and* outpout buffer are fully read/write. About the crash due to unmapped memory, using scatterwalk_copychunks() that will map and copy each block fix the issue. Using this api and copying full block will also fix unaligned data access, avoid early copy of in/out buffer, and make useless the extra alignment constraint.

2021-11-26crypto: qat - do not rely on min versionMarco Chiappero

In any case the minimum version requirement for compatibility is an inadequate and obsolete approach which should be removed. At this time compatibility can be assured across the currently available versions.
