- Allow applications to interact with TA via IOCTL interface, with one device node per TA/token to allow access control policies to be enforced. - Validate the request parameters - Add support to to serialize request data from application and deserialize response from the TA - Include process name as part of request to enable TA to log required info to nvlog buffer Jira ESSS-1713 Change-Id: I9e4c4687ecb6e01b0d88130fd640a9b4a59676aa Signed-off-by: Nagaraj P N <nagarajp@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3282272 Reviewed-by: Sandeep Trasi <strasi@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> Reviewed-by: Leo Chiu <lchiu@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: buildbot_gerritrpt <buildbot_gerritrpt@nvidia.com> Reviewed-by: svc-percl-checker <svc-percl-checker@nvidia.com>
