* Apply the Broadcom Wi-Fi quirk to Macs without a T2
brcmfmac lets the Wi-Fi firmware run the WPA handshake itself, and on Apple
hardware that offload fails against an access point in WPA2/WPA3 transition
mode: the client associates, the four-way handshake never completes, and
NetworkManager reports the password as wrong. feature_disable=0x82000 turns off
the firmware supplicant and authenticator so wpa_supplicant does the handshake
in software.
That quirk already shipped, but only for Macs with a T2 chip. The bug is in the
Broadcom firmware rather than in the T2 bridge, so it was never the right thing
to gate on: a MacBookPro11,4 has BCM43602 with 2015 firmware, fails exactly this
way, and got nothing. Gate on the hardware that actually has the firmware — an
Apple machine with a Broadcom wireless part — which covers both.
Moving it out of fix-t2.sh also leaves one owner for the file. Two leaves writing
the same config would have meant the later one silently winning, decided by an
ordering in all.sh nobody would think to check.

* Gate the Broadcom Wi-Fi quirk on the T2 ID or a brcmfmac chip ID
Sniffing lspci for an Apple vendor with a Broadcom network controller made T2
Macs depend on a detection line they never needed: they carry a T2 PCI ID that
is always there, and the class name half of `lspci -nn` comes from the pci.ids
database. Keep their original gate untouched.
Naming the rest by DMI model does not hold up either, because the model year
does not predict the part. A MacBookPro11,4 from Mid 2015 carries a BCM43602
and needs this; a MacBookAir7,2 from Early 2015 carries a BCM4360 and does
not. Covering the lineup by name takes around twenty identifiers across four
product lines and grows every time Apple ships hardware.
The set has an exact definition already: the PCI IDs brcmfmac binds, from the
driver's own brcm_hw_ids.h. That reaches the 2016 and 2017 MacBook Pros and
the T2-less iMac19,1 and iMac19,2 that a hand-written list missed, and it
leaves out the BCM4360 Macs for free, since their out-of-tree wl driver would
never read a brcmfmac option anyway.
Matching an exact vendor:device ID also drops the piped `grep -q`, which
returns 141 under pipefail once the producer is killed by SIGPIPE (#6608). The
test runs the leaf with pipefail so the chatty lspci stub proves it.

* Fix Macs already installed without the Broadcom Wi-Fi quirk
The quirk is written at install time, so a machine set up before it shipped
never gets it, and no pre-T2 Mac ever did. Those installs still fail the WPA
four-way handshake against an access point in WPA2/WPA3 transition mode,
which is the state the reporter had to repair by hand.
Appending leaves anything else in the config alone: modprobe reads every
options line for a module, and nothing else sets feature_disable. Only an
active options line counts as already applied, and the driver keeps the old
behaviour until it reloads, so this asks for a reboot rather than pulling
brcmfmac out from under a connection that currently works.

A fresh install on a Dell XPS 14 spent 73s in "Configuring system", and two
silent gaps in the install log account for 66s of it. Both are the same
redundant work.
hardware/all.sh ran ipu7-camera.sh before ptl-kernel.sh. intel-ipu7-camera
pulls in ipu7-drivers, vision-drivers and v4l2loopback, so DKMS compiled all
three against the stock linux kernel and built a UKI for it. ptl-kernel.sh
then installed linux-ptl, which recompiled the same three modules against the
new kernel, and its pacman -Rdd of linux followed with three dkms removes and
yet another UKI rebuild. The log shows four UKI builds where one would do, and
everything the first script produced was deleted 42 seconds after it was made.
Running the kernel swap first means the DKMS modules are only ever built
against the kernel the machine actually keeps, which returns roughly 25s.
ptl-kernel.sh still installs linux-ptl before removing linux, so one redundant
UKI build for the stock kernel remains. Removing first would save it but would
leave the machine with no kernel at all if the linux-ptl install failed, so the
safe order stays.

Laptop speakers ship voiced by the vendor's Windows DSP layer, which Linux does
not get. A tuning restores that as a PipeWire filter-chain in front of the
internal speaker sink, matched to the machine by DMI string and expected sink.
Adding a laptop is a directory under default/audio/tunings with two files and no
new code: matching is data. The XPS 14 DA14260 tuning included here was derived by
measuring the xps-audio-linux EasyEffects profile (MIT) and fitting a biquad chain
to it, so no impulse response or other upstream asset is redistributed. It measures
1.24 dB RMS against that reference, and matches its dynamic range within 0.1 LU --
the reference's multiband compressor turned out to contribute nothing, so a linear
chain replaces it. Bass Q is capped deliberately: a closer magnitude fit swung
group delay 31 ms across 63-80 Hz, which smears bass transients.
The graph runs as its own PipeWire client under its own config name rather than
loading into the audio daemon. The daemon only reads its config at startup, so a
daemon-loaded tuning could only be switched by restarting PipeWire -- which drops
every PulseAudio client's connection, and applications that do not reconnect
(Spotify) then have to be restarted by hand. Hosting it separately also contains
failure, since a malformed tuning breaks only that service.
Three things about the surrounding audio graph needed fixing for this to behave:
- Volume must live downstream of the tuning. omarchy-audio-output-sink is now the
single definition of which sink an output's volume really uses, shared by the
volume keys, the output switcher's OSD and the audio panel, so they cannot
disagree. It resolves the current default output, which keeps it correct when
headphones are selected while a tuning exists.
- The tuning's own output is a movable sink input, so rerouting "all streams" to a
newly selected output would drag the processing onto headphones, or into the
tuning's own sink, which is a cycle. It is pinned, and stream moves are limited
to streams carrying an application.name.
- The physical sink a tuning fronts is not independently selectable, since picking
it would only bypass the tuning, so it is kept out of the output list.
Applying happens at first-run, not finalize-user, because finalize-user also runs
in the ISO chroot where there is no audio server and nothing would retry.
