@cwt:matrix.orgcwtHow can I write assembly in C (using asm) which can be added "th." prefix if I build the code for t-head or I need to use #if-#else block and then write 2 sets of that asm?05:03:03
@telegram_492445660:t2bot.ioPierce Andjelkovic Is this new? Just found this amazing item on AliExpress. Check it out! AU$15.49 | LCPI Rockchip RV1106 RISC-V Architecture 256MB Flash AI Development Board

It has big ARM Cortex-A7 core and small RISC-V MCU core.

SG2002 and SG2000 are more interesting in my opinion.

GNU inline assembler uses string literals, which means that the standard C string literal concatenation rules apply. use something like asm( PREFIX "instruction" : OPERANDS) where PREFIX is "th." or ""

@codingvoid:matrix.orgcodingvoidhttps://github.com/riscv-non-isa/riscv-ap-tee/ looks like Management Engine 2.0 Although I guess there is at least a small possibility of having open source in there.13:44:57

@839ty9:matrix.org839ty9ap-tee, for Advanced Persistent Threat? Marketing departments will love this :)00:42:02
@839ty9:matrix.org839ty9at least op-tee didn't have 00:43:01
@839ty9:matrix.org839ty9 * at least op-tee didn't have any major branding issue...00:43:21

This is more in the realm of Intel TDX.

Rivos are doing a lot in this space for RISC-V.

@codingvoid:matrix.orgcodingvoidIf it is anything like ARMs op-tee the I am rather sceptical. Running so called "trusted" vendor firmware on your device with high priviledges is a bit scary. Espacially regarding security and privacy. In my experience less vendor firmware with high priviledges usually increases my security.17:37:25
@psydroid:matrix.orgpsydroidThe question will be if we will be able to buy hardware without such service processors and "trusted" vendor firmware17:41:16
@codingvoid:matrix.orgcodingvoidThat will be my hope. It would also be a step forward if you could by Hardware where these "trusted" applications are open source. But realisticly none of these "trusted" applications will be open source and will be just like Samsung Knox.17:52:41

The trust is not expected from you toward anything.
They call it that because content producers and closed-source software vendors trust that their stuff isn't exposed. ^^
