@philvischer, loved you geeking out over Blender in this weeks episode! Though I’m only marginally artistic, it puts a smile on my face to fire up Blender throw together a 3D model just for fun

@_AlexGraf @haerwu @linux4kix @Arm Using optee-supplicant to mediate RPMB transactions still looks like the best way forward, but it still is technically difficult to do and we don't have a complete solution yet

[Grant Likely @glikely]

@_AlexGraf @haerwu @linux4kix @Arm I'm also not convinced that routing SDHCI IO through TrustZone is either a desired or performant solution

[Grant Likely @glikely]

@haerwu @linux4kix @Arm That alone I think makes eMMC the more attractive option for an SBC. It's not just the component cost, but also the board space and a preference to minimizing the number of programmable devices on a board.

[Grant Likely @glikely]

@haerwu @linux4kix @Arm Can also be solved with a dedicated boot SPI; preferably owned by the secure world

[Grant Likely @glikely]

@haerwu @linux4kix @Arm Yes, both those things need to change. Devices using eMMC already have the needed hardware: Firmware can be stored in the boot areas, and firmware settings can move to the RPMB, leaving the user area entirely to the OS

[Grant Likely @glikely]

@haerwu @linux4kix @Arm They will be, but it takes time to change the way an entire ecosystem works. I think the evidence shows we're going in the right direction. We've proven SBCs can boot generic images and embedded SoCs don't need custom stacks. Next step is to get more platforms on board

[Grant Likely @glikely]

@haerwu @linux4kix @Arm I don't disagree. This is part of what I'll be talking about in my roadmap session next week. Having generic OSes boot is huge step forward that I am very proud of, but there is still work to be done to guarantee a functional platform.

[Grant Likely @glikely]

@haerwu @Arm Good feedback, thanks. I'll look into ways that can be stated clearer

[Grant Likely @glikely]

Very proud to be part of the team that made this happen. Well done everyone!

@haerwu @Arm Not true. A platform that only runs the vendors image cannot be certified. Platforms must boot at least two 3rd party generic OSes. ‘Level 0’ only happens when support exists, but hasn’t landed in a full release. e.g., Fedora Rawhide or SUSE Tumbleweed

[Grant Likely @glikely]

@haerwu @Arm Think bigger! Yes, 50 looks small, but change takes time. A year ago we didn’t have any IR certifications. Those first 50 are merely the proof that SystemReady solves interoperability on Arm devices. There are plenty more to come.
