crypto: qat - remove unnecessary description from comment Remove extra description from comments as it is not required. This is to fix the following warning when compiling the QAT driver using the clang compiler with CC=clang W=2: drivers/crypto/intel/qat/qat_common/adf_dev_mgr.c:65: warning: contents before sections drivers/crypto/intel/qat/qat_common/adf_isr.c:380: warning: contents before sections drivers/crypto/intel/qat/qat_common/adf_vf_isr.c:298: warning: contents before sections Signed-off-by: Adam Guerin <adam.guerin@intel.com> Reviewed-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: qat - add fatal error notification Notify a fatal error condition and optionally reset the device in the following cases: * if the device reports an uncorrectable fatal error through an interrupt * if the heartbeat feature detects that the device is not responding This patch is based on earlier work done by Shashank Gupta.

crypto: qat - use kcalloc_node() instead of kzalloc_node() As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc_node() function instead of the argument count * size in the kzalloc_node() function.

crypto: qat - add infrastructure for error reporting Add infrastructure for enabling, disabling and reporting errors in the QAT driver. This adds a new structure, adf_ras_ops, to adf_hw_device_data that contains the following methods: - enable_ras_errors(): allows to enable RAS errors at device initialization. - disable_ras_errors(): allows to disable RAS errors at device shutdown. - handle_interrupt(): allows to detect if there is an error and report if a reset is required. This is executed immediately after the error is reported, in the context of an ISR. An initial, empty, implementation of the methods above is provided for QAT GEN4.

crypto: qat - add internal timer for qat 4xxx The power management feature in QAT 4xxx devices can disable clock sources used to implement timers. Because of that, the firmware needs to get an external reliable source of time. Add a kernel delayed work that periodically sends an event to the firmware. This is triggered every 200ms. At each execution, the driver sends a sync request to the firmware reporting the current timestamp counter value. This is a pre-requisite for enabling the heartbeat, telemetry and rate limiting features.
