UEFI is an answer to x86 platform dependency upon a badly designed and way
outdated method of controlling the configuration and control of hardware that
has up to this point been done via BIOS.
Current motherboards that have UEFI, *emulate* a BIOS in the UEFI so that the
x86 based operating systems don't need anything new to run. That will change.
The Linux kernel already has a lot more flexibility regarding information
available at boot time.
The whole trusted computing initiative from years ago has settled into this new
tool, the UEFI, instead of the former effort to brand it into the hardware
layer.
Essentially, UEFI is a much larger programmable 'space' than the old BIOS.
Therefore, it is possible to introduce DRM into the UEFI.
Also, RedHat/Fedora have not made a commitment yet. The discussion has only
just begun in earnest, due to the new exposure to the issues involved.
As for what is and is not possible with this new 'trusted computing' approach,
if trusted is 'on', then you cannot build your own kernel or do anything other
than run signed applications.
For most serious Linux users, we will need to have the ability to turn trusted
mode 'off' entirely to have the same freedoms we enjoy today.[ Reply to This | Parent | # ]
