Hi Jonathan，all Do you have any topic to sync next Tuesday？ Since it is Christmas next week，we can put off the meeting after the holiday whenever you want to sync.

Linaro OP-TEE Contribution, LOC, monthly meeting November 26

by Jens Wiklander

Hi, Tomorrow, Tuesday, it's time for another LOC monthly meeting. For time and connection details see the calendar at https://www.trustedfirmware.org/meetings/ The fTPM pull request https://github.com/OP-TEE/optee_ftpm/pull/1 to import the TA-specific parts of fTPM into optee_ftpm.git is even more relevant now that https://github.com/microsoft/ms-tpm-20-ref/pull/112 removed Samples/ARM32-FirmwareTPM/optee_ta from upstream. Can we start to review https://github.com/OP-TEE/optee_ftpm/pull/1? Are there any other topics? Thanks, Jens

Linaro OP-TEE Contribution, LOC, monthly meeting October 22

by Jens Wiklander

Hi, Tomorrow, Tuesday, it's time for another LOC monthly meeting. For time and connection details see the calendar at https://www.trustedfirmware.org/meetings/ I've started the Pull Request https://github.com/OP-TEE/optee_os/pull/7054 to import the TA-specific part of fTPM into the OP-TEE git. It appears that MS has filed for patents on fTPM. How does that affect downstream usage? Would it be safer or more convenient for downstream if the fTPM TA was in a separate git instead of the optee_os git? Are there any other topics? Thanks, Jens

Linaro OP-TEE Contribution, LOC, monthly meeting September 24

by Jens Wiklander

Hi, Tomorrow, Tuesday, it's time for another LOC monthly meeting. For time and connection details see the calendar at https://www.trustedfirmware.org/meetings/ I've started to work on importing the TA specific part of fTPM into the OP-TEE git, based on the patches published at https://github.com/zeschg/ms-tpm-20-ref/tree/feat_add_tee_crypto replacing the third-party crypto library with TEE Internal core API. I'd appreciate help reviewing this when I publish the work. We'll need a way to test that the imported fTPM implementation works as expected, preferably something we can have in our CI loop. Are there any other topics? Cheers, Jens

Linaro OP-TEE Contribution, LOC, monthly meeting August 27

by Jens Wiklander

Hi, Tomorrow, Tuesday, it's time for another LOC monthly meeting. For time and connection details see the calendar at https://www.trustedfirmware.org/meetings/ The RPMB patches to handle RPMB processing internally in the kernel are about to be merged, see https://lore.kernel.org/lkml/20240814153558.708365-1-jens.wiklander@linaro.…. Progress on fTPM have slowed down recently. Jan and colleagues at Siemens have published patches at https://github.com/zeschg/ms-tpm-20-ref/tree/feat_add_tee_crypto replacing the third-party crypto library with TEE Internal core API. Good work! What should be our next step? Are there any other topics? Cheers, Jens

Linaro OP-TEE Contribution, LOC, monthly meeting March 26

by Jens Wiklander

Hi, Today it's time for another LOC monthly meeting. I'm sorry for the short notice. For time and connection details see the calendar at https://www.trustedfirmware.org/meetings/ We have the OP-TEE 4.2.0 release scheduled for 2024-04-12. The last patchset (v3) for adding an RPMB subsystem https://lore.kernel.org/lkml/20240227153132.2611499-1-jens.wiklander@linaro… is attracting some interest. Any other topic? Thanks, Jens

For time and connection details see the calendar at https://www.trustedfirmware.org/meetings/ Moving the RPMB part of tee-supplicant processing into the kernel is making progress.
