This commit expands the camera-diagnostics driver to add support for ISP PFSD tests. The implementation: - Adds diagnostics IVC communication between kernel and RCE firmware - Implements ISP SDL test vector loading, verification, and execution - Provides proper memory allocation and IOMMU mapping across devices - Supports multiple ISP instances with chip-specific configurations (T234/ISP6 and T264/ISP7) - Creates sysfs interface for diagnostic status reporting - Adds proper error handling and resources cleanup - Implements CRC validation for test vectors The driver enables hardware safety diagnostics for camera subsystems to ensure reliability and functional safety of the camera pipeline. New header files: - camrtc-diag-messages.h: Defines messages for IVC communication - camrtc-diag.h: Contains common diagnostic data structures Jira CAMERASW-32042 Change-Id: I9a892b40891cffc3d460723d9fdc92854c6cda85 Signed-off-by: Mohit Ingale <mohiti@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3313001 Reviewed-by: Vincent Chung <vincentc@nvidia.com> GVS: buildbot_gerritrpt <buildbot_gerritrpt@nvidia.com> Reviewed-by: Semi Malinen <smalinen@nvidia.com> Reviewed-by: Frank Chen <frankc@nvidia.com> Reviewed-by: Bhushan Rayrikar <brayrikar@nvidia.com>
