Well, maybe AMD does at least some security reviewing on their own? /s ARM could be a affordable alternative to x86 if that works for you.

ARM could be a affordable alternative to x86 if that works for you.
- tdb7893 9y agoWhat's the state of x86 emulation on ARM? Using ARM before that might be a dealbreaker. If I remember correctly Microsoft was working on it
- my123 9y agoRelease is on track for December 2017, but Qualcomm chips have ME-like firmware too (from SCM to the modem)
- agumonkey 9y agoit's less painful if you only pay half for being pwnd
- bryanbuckley 9y agoAMD PSP is an ARM core. Running some derivative of Trustonic OS (based on L4), if I'm not mistaken.
- em3rgent0rdr 9y agoSomewhat numerous that the most secure OS kernel (the L4) is utilized in a bad way to result in a less secure system overall.
- disconnected 9y ago> ARM could be a affordable alternative to x86 if that works for you. Even the open source friendly Raspberry Pi relies on proprietary blobs and proprietary firmware, with vast parts of the documentation only being available to system integrators (meaning: not you) under an NDA. Theirs is a Broadcom chip, but my understanding is that the scenario is pretty much the same for other ARM vendors. If the chip is anything more complicated than your average 8-bit micro-controller, expect it to be running some kind of "system" which is, of course, closed source.
- khedoros1 9y agoThe stuff running on the ARM itself is all open, but the firmware blob runs on a separate CPU with a different instruction set, which has a view of the entire memory map of the device and ultimate control over the device's behavior (sound familiar?). I may be wrong, but my impression is that a lot of the other ARM boards out there have the ARM chip as the main CPU, and without a management chip watching it. In any case, a board like that, or a Pi with a reverse-engineered firmware blob (currently in development) would be better than the Raspberry Pi as it is now.
