This is the limit used by Linux kernels since the 2.6 era, as reported
in the bzImage header as well as the COMMAND_LINE_SIZE definition in
setup.h.
The previous allocation of almost 2 MB was excessive and would have
also overlapped the memory region used for ACPI tables had a long
enough command line been provided.
We will use the area freed up by this change for the setup_data in the

cross-compilation requires additional configuration that depends
heavily on the host platform. Unfortunately cargo cannot be
configured on a per host platform basis so this has to be done
manually.
Most developers are just using native compilation (and using
the containers for everything else). So we can slim our
install-deps scripts a bit.
To verify the updated install scripts, this change includes
containers to simulate a fresh developer workstation that
can be used to verify out of the box workflows.

The backend roughly mirrors how the FFmpeg decoder backend is

This adds a new dt node identified by "qemu,vm-watchdog". The watchdog
is instantiated per-cpu and each instance has the following layout
described in this document:
https://docs.google.com/document/d/1DYmk2roxlwHZsOfcJi8xDMdWOHAmomvs2SDh7KPud3Y/edit?resourcekey=0-oSNabc-t040a1q0K4cyI8Q#heading=h.4hbqud2zl941
The watchdog uses an internal clock which is driven by the
timerfd at regular intervals. When the internal clock expires, a counter
value is decremented. When the counter register reaches value "0",
the watchdog expires. To prevent 'watchdog expiration', regular pet
events should be sent from the guest kernel driver.

We are going to use separate policy files per device for the following scenarios:
1) Regular in-VMM virtio device,
2) Virtio device over vhost-user,
3) Virtio device over Vvu.
Each of these scenarios require slightly different policies as a jailed
device process needs to allow not only the system calls necessary for
the device to function, but also those required by the virtio transport
in use.
This CL adds a README.md file to the seccomp directory that details the
naming and policy inclusion rules, and updates the serial, xhci and
coiommu policies to follow the naming scheme.
Vhost-user and VVU policy files will be added along with support for
