linux-ps5 currently ships no wifi driver — the PS5 onboard wifi is NXP
IW620 (not the upstream mwifiex), which lives at ps5-linux/ps5-linux-
mwifiex as an out-of-tree patch against nxp-imx/mwifiex. Users have to
clone that repo + run install.sh on the target, which needs gcc + kernel
headers and is a manual step every kernel bump.
Build it in the kernel-builder container right after the kernel: clone
both repos, apply ps5-iw620.patch, make against the kernel src tree,
install mlan.ko+moal.ko into /out/staging/lib/modules/$KVER/extra/
ps5-iw620/ with the NXP modprobe options + autoload conf. depmod -b
refreshes the index. All package formats (.deb/.rpm/.pkg.tar.zst) then
include the driver automatically.
MWIFIEX_REPO / MWIFIEX_REF overridable via env in case downstream wants
to test a fork or specific commit.
Both packagers copied the staged UAPI headers with:
cp -a /out/staging/headers/usr "$DEST/usr"
Because $DEST/usr already exists (modules live under $STAGING/usr/lib/modules,
and other files may be staged under $PKG/usr), cp placed the source directory
inside the destination, producing a nested usr/usr/include/ path. The headers
were therefore installed at the wrong location and not found by builds.
Merge the contents with cp -a .../usr/. "$DEST/usr/" so the headers land at
the expected /usr/include/linux/... path in both .deb and .pkg.tar.zst
packages.
