Continue your argument. Don't stop at solar. In the next 5 billion years we must leave. How do you propose we do that if we focus on fast fashion and changing cars every 2 years?

Most consumption is arbitrary.

Earth is limited. Resources are limited. You can't recycle to infinity. Each time you recycle something, the material recovered is worse than before. Steel is weaker, plastic has impurities and is not clear/transparent, paper isn&

I appreciate your detailed reply. I think we are looking from different perspectives. You are correct in an item-by-item way, but you need to put them all together and see the bigger picture. In my comment, it may have made a mess confusing

Until UEFI and secure boot, SMM would run code provided by the BIOS. BIOS was updatable, moddable, replaceable. See coreboot and numerous BIOS mods such as wifi whitelist removal. Trustzone usually runs code from eMMC. These chips are progr

Oh, I didn't know that! There goes freedom in the ARM world too.

Then you can load them in u-boot and there's no need for any ohter blob.

You can write to CR0 from a DOS COM program while in V86 mode??? :o Wouldn't that cause a GPF / segfault / EMM386 crash?

True. But I'm voting with my wallet supporting those manufacturers that upstream to mainline kernel and don't require any signed firmware to boot.
403.
by M95D 8mo ago
Let's say some hw manufacturer would open-source the required specs to implement it on it's chips. (Very unlikely, but let's say they do...) So what? Dangerous capabilites remain.

You can convert a DTB blob back into source code: dtc -I dtb -O dts -o devicetree.dts blob.dtb Big, biiig, biiiiig difference! PS: You can also examine it directly as a directory tree in /sys/firmware/devicetree/*

by M95D 8mo ago
It's either a DTB per device or a firmware blob per device . I'll take the open source device tree anytime!

UEFI switches the CPU into 32bit v86 mode or directly in 64bit mode and you can't go back to real mode without a CPU reset, which v86 won't allow (you don't have ring -2 privileges) and 64bit mode can't do at all. I don&

You actually confirmed what I said. :)

by M95D 8mo ago
I don't know what you're talking about. If the device boots, you find the device tree in /sys/firmware/fdt, or in unpacked human-readable form in /sys/firmware/devicetree/* .

by M95D 8mo ago
Will you PLEASE stop promoting UEFI and ACPI?! These are closed-source blobs that the manufacturers will never update and have complete control over the system at ring -2. Why would you even consider it? Device tree does the same thing an

^ that! You can't run a COM program today. Not without emulation. Recent PCs can't even run DOS EXE because they're missing the BIOS interrupts most DOS programs use.

I can't say anything about the German gov. I don't live there and I have no info. But I wouldn't call bureaucrats "capitalists" either.

Shouldn't you manage permissions from groups instead of hacking udev? And why do you have modemmanager if you don't have a modem?

by M95D 8mo ago
Probably because nobody targeted them yet.

None of it matters. If the device has a SIM card (virtual or physical), it will execute commands sent over the network. It's required by the GSM/LTE standards. The best you can hope for is to have separate SoC for the OS and separ
