A Hardware tab: what the machine is made of

Browse Source 
Per machine, like every other page. Four tiles — processor, memory, storage,
graphics — over a card for each.

Memory is the part that had nowhere to live before: every slot, with the
module's size, type, form factor, rated and running speed, maker, part
number, serial, rank and voltage, and the empty slots marked empty. A module
whose maker is only a JEDEC id gets a name when it is one we know and keeps
the number when it is not, because a wrong name is worse than a code.

Everything is read from what Debian already has: dmidecode for the parts only
the firmware knows, lscpu, lspci, sysfs. None of it changes under a running
kernel, so it is read once and kept for ten minutes; Re-read is for the one
thing that does change, a drive plugged in.

Every reader is allowed to come back empty. A machine with no dmidecode, no
root to read it with, or no PCI bus at all still gets a page, with a note
saying what was missing and why. Checked against the Mac mini, which is all
three cases at once: no SMBIOS memory table, a GPU only the device tree knows
about, and cores that are not all alike — lscpu counts one cluster as "cores
per socket" there, so without SMT the thread count is the honest answer.
