We can't actually access the UEFI ROM from userspace, but the PCR0 is a hash
built from the ROM itself. We could use this value to ensure the firmware has
been written correctly, and that the PCR0 matches the expected value specified
in the metadata.
Future metadata from the LVFS will set the protocol the firmware is expected to
use. As vendors love to re-use common terms like DFU for incompatible protocols,
namespace them with the controlling company ID with an approximate reverse DNS
namespace.
This also allows more than one plugin to define support for the same protocol,
for instance rts54hid+rts54hub and synapticsmst+dell-dock.
This solves issues with implementations that require 4k alignment
of pages in BIOS which is seen on certain architectures.
The UEFI spec prescribes that the "minimum" size is the size of
the EFI header but that this may be increased up to larger sizes
due to extended header entries.
This mirrors the update process over DP aux to run the ESM update
first.
The thought process is as follows:
The "version" displayed doesn't show ESM version, only standard
bank version.
So if the update fails for the ESM then because the update of the
standard happening first it would never be flashed.
`g_ascii_strtoull` returns 0 and sets `errno` to `-EINVAL` only when
the base is invalid. It's hardcoded to `16` so this is impossible.
Reading `-EINVAL` from `errno` is incorrect in these circumstances.

This makes startup quicker as we no longer have to probe every USB device, and
is now possible with the new GUIDs we added. Devices not using the
specification-provided values can (and already are) worked around with quirks.
The LVFS has always sent components with the old-style '<metadata>' section
rather than the new-style '<custom>' section, and when using appstream-glib
we just accepted either element name. Although the LVFS has just been fixed to
use the new name, old metadata might be present on the system already.
When all clients have downloaded new metadata we can revert this, perhaps in a
couple of weeks time. Until then, the belt-and-braces approach is probably a
good idea.

The client uses GObject introspection to use the libfwupd2 library.
The client offers a reduced set of commands, but may be useful in some
environments.
This allows plugins to load an archive supplied as the 'deliverable' of the
cabinet archive. This means plugins can bundle up a set of images in a cross
platform way, for instance adding boot.img+os.img+manifest.xml into a zip file,
rather than having to (ab)use the DfuSe file format or deal with libarchive
directly.
Otherwise this would cause fwupd to sit in an endless loop when providing a bad
image.
This additional enum is only available in EC16, but since it doesn't break existing
API on older EC images, don't bump minimum requirement to EC16 yet.
This metadata key is now unnecessary, as firmwares are expected to set the
version format in the metadata.
If the metadata is missing, the LVFS allows a per-vendor default for non-semver
release versions which is now unconditionally set in metadata.
Plugins are allowed to 'opt-out' of this behaviour using _RULE_INHIBITS_IDLE.
This should be used where waking up the hardware to coldplug is expensive,
either from a power consumption point of view, or if other artifacts are going
to be seem -- for instance if the screen flickers when probing display devices.
This functionality is also inhibited when the actual upgrade is happening,
for obvious reasons.
Admins can turn off this auto-sleep behaviour by editing the daemon.conf file.

This speeds up matching for GUIDs by about 90%, taking the query from 3.17ms to
about 0.33ms on my Thinkpad. This is more important for slow ARM hardware,
where strcmp() is more expensive than on x64.
This matches what a lot of other projects do, and means we can easily format
the release notes back into NEWS format, but also into HTML and Markdown.
This also means we can show the correct update description in gnome-software
when building a flatpak, rather than falling back to the generic project
description.
