TF-A TechForum this week

by Joanna Farley

Hello TF-A Community, The meeting invite this week has been updated with an agenda. In case you have not seen this the details are: The TF-RMM component was published last week and was announced in this mailing list: https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… This week Javier Almansa Sobrino of the TF-RMM team would like to present on the TF-RMM Unit test framework The TF-RMM Unit test framework allows the exercising and validation of the software components of TF-RMM to be performed natively on the development host, making the development of new features, as well as the debugging of existing ones, easier. This talk will introduce this framework as well as the fake_host architecture for TF-RMM which allows the building and running of TF-RMM natively on the development host. We will also discuss how to implement unit tests for different components and we will introduce some features such as code coverage test for TF-RMM.

Minimal kernel/firmware on Rock64 (rk3328)

by Robert Meissner

Hello, i found TF a very interesting project, however I would like to get booted with a really minimal firmware/kernel. I have a Rock64 with RK3328 Rockchip which I am trying to boot from sdcard with following sources: https://gitlab.com/jahro_me/sos/-/tree/master/ I have tried to setup UART for the device as described in the manual https://opensource.rock-chips.com/images/9/97/Rockchip_RK3328TRM_V1.1-Part1… On page 13 it states, the BOOT_ROM, INT_RAM is located at 0xffff0000. I have used this adress in kernel_entry https://gitlab.com/jahro_me/sos/-/blob/master/boot.s and in the main section https://gitlab.com/jahro_me/sos/-/blob/master/link.lds However, I could not get the kernel booted. I am not sure, if I need to remap the memory and how to do it. I guess, i should enable it with SGRF_SOC_CON2. Could anyone please help out to get the output, "Hello, You Rock!"? Best regards, Bob

PSCI OS-initiated mode

by Wing Li

Hi, The PSCI specification defines two different power state coordination modes for CPU_SUSPEND that can be used to put a core or a group of cores into a low-power state. These modes are the platform-coordinated mode (default) and the OS-initiated mode (optional). OS-initiated mode is currently not supported by TF-A, while both modes are supported by the Linux Kernel. Requesting reviews for the patches [1] adding support for OS-initiated mode in TF-A and the corresponding tests in TF-A-Tests. Any feedback and comments are much appreciated. Thanks in advance!
