Changes in sysfs-class-tee en Copyright 2015 Java f0c84315 - optee: probe RPMB device using RPMB subsystem http://172.16.0.5:8080/history/linux-6.15/Documentation/ABI/testing/sysfs-class-tee#f0c84315 optee: probe RPMB device using RPMB subsystemAdds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe anduse an RPMB device via the RPMB subsystem instead of passing the RPMBframes via tee-supplicant in user space. A fallback mechanism is kept toroute RPMB frames via tee-supplicant if the RPMB subsystem isn'tavailable.The OP-TEE RPC ABI is extended to support iterating over all RPMBdevices until one is found with the expected RPMB key alreadyprogrammed.Signed-off-by: Jens Wiklander <jens.wiklander@linaro.org>Tested-by: Manuel Traut <manut@mecka.net>Reviewed-by: Sumit Garg <sumit.garg@linaro.org>Link: https://lore.kernel.org/r/20240814153558.708365-5-jens.wiklander@linaro.orgSigned-off-by: Ulf Hansson <ulf.hansson@linaro.org> List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-tee Wed, 14 Aug 2024 15:35:58 +0000 Jens Wiklander <jens.wiklander@linaro.org>
