I think Nvidia have just certified a T214 (Mariko) Jetson board with the Khronos group. If you take a look at Khronos’s Vulkan conformant products page here, you’ll see a Nvidia Confidential device at position 353. This isn’t that strange to begin with (you’ll see quite a few Qualcomm and Intel undisclosed/confidential devices on the page), but the interesting thing is that it’s running a new Tegra SoC. You can see it’s ARMv8a and runs Linux for Tegra R32. My first thought here is it’s an Orin board (the successor to Xavier which Nvidia showed in a roadmap last year), but running over to the Linux for Tegra source code there’s an interesting little change from R31 to R32 in this file: several references to T214. The same T214 we’ve seen referenced in Switch firmware.
The actual changes in L4T don’t tell us much (Nvidia likely scrubbed all T214-related code from the public release, but missed these references in a couple of comments), but there are actually a few things I think we can deduce from this. Firstly, I don’t think it’s a coincidence that T214 references appeared in L4T in the same release that was used to certify this confidential Nvidia device; I think that device is using T214. Secondly, I think the fact that it’s a L4T-based Khronos-certified device means that it’s not a Switch Pro/Plus/Mini/etc. or a devkit, as Switch itself uses a different OS, and even if L4T was used in Switch devkits, there would be no reason to have them certified by Khronos, that’s only intended for devices for public sale.
If you look at devices which are Khronos-certified and run L4T, they all fall in a single category: Jetson boards. Releasing a Jetson board for a new Tegra chip isn’t exactly surprising, but what is interesting is that it means T214/Mariko isn’t a Nintendo-exclusive chip . It’s being used by Nvidia in other devices, and possibly being sold to other manufacturers as well (as a large part of the reason Jetson boards exist is for hardware designers to use for prototyping/development of Tegra-powered hardware) […]
En resumen:
-
Khronos nombra un nuevo Tegra.
-
Aparece en el código de linux un nuevo Tegra: el T214, el T214 hasta ahora sólo se había nombrado en el SO de Switch hace más de un año, es el SoC nombrado en el SO con el nombre en clave Mariko.
-
Todo dispositivo certificado por Khronos basado en L4T es para placas bases Nvidia Jetson.
Por tanto: en principio Mariko no es un SoC exclusivo de Nintendo, al igual que el Tegra X1 que lleva Switch no es un SoC exclusivo.
Por otro añadir que donde se nombra el nuevo SoC sale así:
“Platforms: T210, T214, T186”
Siendo:
T210 -> X1
T186 -> X2
T194 -> Xavier (Tegra especializado en IA. Aviso: Pegasus son dos Xavier y cía, no es un nuevo SoC)
¿? -> Orin (la siguiente generación de placas de IA tras Xavier)
Obviamente no es Orin (no tiene sentido que Switch nombre un SoC tan especializado en IA), y teniendo en cuenta que se nombran X1 y X2, ¿hablamos que Mariko es Tegra X3?, ¿X1.5? (anda que la forma de numerar los SoC que tiene Nvidia X-D ), ¿Mariko es también el SoC de la rumoreada tableta Shield con modo sobremesa?
