mesh/merge-gate pass: builds mesh-host → ace, g14, novox, shanks; no bus step; every machine composes with the change as it did without (4 of 4 compose)
An APU's integrated graphics and Intel's second (MMIO) view of a package made a machine
report a power meter the sampler would not read, so its bar could only say not
measured.
The power module is on every machine and its bar blocks apply only where the
hardware is. Two capabilities read from the kernel let the controller compose them
there and nowhere else: battery (a Battery supply not scoped to a device) and
power-meter (a system battery, a powercap package counter, or a graphics device
reporting its power).
