[PATCH v8 0/5] Introduction of a remoteproc tee to load signed firmware

by Arnaud Pouliquen

Main updates from version V7[1] Update the series based on Mathieu Poirier's comments. Details of the updates are listed in the commit messages of the patches. [1] https://lore.kernel.org/linux-arm-kernel/20240611073904.475019-1-arnaud.pou… base-commit: 1613e604df0cd359cf2a7fbd9be7a0bcfacfabd0 Description of the feature: -------------------------- This series proposes the implementation of a remoteproc tee driver to communicate with a TEE trusted application responsible for authenticating and loading the remoteproc firmware image in an Arm secure context. 1) Principle: The remoteproc tee driver provides services to communicate with the OP-TEE trusted application running on the Trusted Execution Context (TEE). The trusted application in TEE manages the remote processor lifecycle: - authenticating and loading firmware images, - isolating and securing the remote processor memories, - supporting multi-firmware (e.g., TF-M + Zephyr on a Cortex-M33), - managing the start and stop of the firmware by the TEE. 2) Format of the signed image: Refer to: https://github.com/OP-TEE/optee_os/blob/master/ta/remoteproc/src/remoteproc… 3) OP-TEE trusted application API: Refer to: https://github.com/OP-TEE/optee_os/blob/master/ta/remoteproc/include/ta_rem… 4) OP-TEE signature script Refer to: https://github.com/OP-TEE/optee_os/blob/master/scripts/sign_rproc_fw.py Example of usage: sign_rproc_fw.py --in <fw1.elf> --in <fw2.elf> --out <signed_fw.sign> --key ${OP-TEE_PATH}/keys/default.pem 5) Impact on User space Application No sysfs impact.the user only needs to provide the signed firmware image instead of the ELF image. For more information about the implementation, a presentation is available here (note that the format of the signed image has evolved between the presentation and the integration in OP-TEE). https://resources.linaro.org/en/resource/6c5bGvZwUAjX56fvxthxds Arnaud Pouliquen (5): remoteproc: core: Introduce rproc_pa_to_va helper remoteproc: Add TEE support dt-bindings: remoteproc: Add compatibility for TEE support remoteproc: stm32: Create sub-functions to request shutdown and release remoteproc: stm32: Add support of an OP-TEE TA to load the firmware .../bindings/remoteproc/st,stm32-rproc.yaml | 58 ++- drivers/remoteproc/Kconfig | 10 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/remoteproc_core.c | 46 ++ drivers/remoteproc/remoteproc_tee.c | 446 ++++++++++++++++++ drivers/remoteproc/stm32_rproc.c | 147 ++++-- include/linux/remoteproc.h | 5 + include/linux/remoteproc_tee.h | 100 ++++ 8 files changed, 769 insertions(+), 44 deletions(-) create mode 100644 drivers/remoteproc/remoteproc_tee.c create mode 100644 include/linux/remoteproc_tee.h base-commit: 1613e604df0cd359cf2a7fbd9be7a0bcfacfabd0 -- 2.25.1

Preparing for OP-TEE 4.3.0

by Jens Wiklander

[BCC all OP-TEE maintainers] Hi OP-TEE maintainers & contributors, OP-TEE v4.3.0 is scheduled to be released on 2024-07-12. So, now is a good time to start testing the master branch on the various platforms and report/fix any bugs. The GitHub pull request for collecting Tested-by tags or any other comments is https://github.com/OP-TEE/optee_os/pull/6906. As usual, we will create a release candidate tag one week before the release date for final testing. In addition to that you can find some additional information related to releases here: https://optee.readthedocs.io/en/latest/general/releases.html Thanks, Jens

[PATCH] driver core: have match() callback in struct bus_type take a const *

by Greg Kroah-Hartman

In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: "Rafael J. Wysocki" <rafael(a)kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- - cc: list suppressed as it just touches too many different subsystems at once, sorry. I tried to hit all of the mailing lists as a bcc: hopefully they don't reject it... arch/arm/common/locomo.c | 4 ++-- arch/arm/include/asm/hardware/locomo.h | 2 +-

[PATCH v2] tee: optee: ffa: Fix missing-field-initializers warning

by Mark-PK Tsai

The 'missing-field-initializers' warning was reported when building with W=2. This patch use designated initializers for 'struct ffa_send_direct_data' to suppress the warning and clarify the initialization intent.
