There are also these packages in QLI; I left them out of this PR as they are not strictly "QTI multimedia" apps, but arguably the audioreach/tinyalsa/tinycompress packages could be...

# audioreach-conf
# - audioreach-conf
# - audioreach-calibration-data

# tinyalsa
# - tinyalsa                                # provides /usr/bin/tinycap, /usr/bin/tinymix, /usr/bin/tinypcminfo, /usr/bin/tinyplay
# - tinycompress                            # provides /usr/bin/cplay, /usr/bin/crecord, /usr/bin/sofprobeclient


# Test suites
# - tinyalsa-tests                          # /usr/libexec/tinyalsa/tinyalsa_test
# - userspace-resource-manager-tests        # provides /usr/bin/UrmComponentTests, /usr/bin/UrmIntegrationTests
# - qmi-framework-utils                     # not sure what this does

# Broken apps - diag
# - qcom-diag                               # broken test app?
# - qcom-diag-router                        # broken service?

# broken sensor apps
# - qcom-sensors-test-apps                  # broken app?
# - sensinghub-session-client               # broken app?

thinking about it, the prebuilts are only released for trixie so this may make sense and won't be fixed for a while?

another separate thought, perhaps we should gate the multimedia image on trixie only ?

looks like there are some build/install issues, but otherwise happy with the changes

fix(debos/rootfs): prefer greetd from backports
372cb07 
The Weston session logs in through greetd/agreety on a virtual
console. greetd 0.10.3-4 in trixie cannot handle accounts with an
expired password, preventing users from changing it on their first
console login.

greetd 0.10.3-7 includes the upstream fix:

  d/p/pam-change-authentication-token.patch: support expired passwords
  Cherry-pick the upstream fix so that an expired password no longer
  causes a login to fail outright: when pam_acct_mgmt() returns
  PAM_NEW_AUTHTOK_REQD, greetd now calls pam_chauthtok() with
  PAM_CHANGE_EXPIRED_AUTHTOK to let the user set a new password.

Pin binary packages built from src to backports so that
greetd >= 0.10.3-7~bpo13+1 is installed.

fix(debos/rootfs)!: drop building DKMS out-of-tree drivers
3cd6513 
The multimedia images install the out-of-tree drivers as DKMS source
packages, so every image build compiles kgsl-dkms and iris-vpu-dkms
against the target kernel. That burns CI minutes and leaves the build
disk almost full and it is unreliable at the moment: camx-dkms never
built under fakemachine at all and was already commented out.

These modules are about to be shipped prebuilt alongside the kernel
package, so pre-emptively stop building them here. Drop the DKMS
source packages together with the gcc and dkms packages installed to
build them and the fakemachine build parallelism workaround along
with the step which cleaned it up.

Until the prebuilt modules land, multimedia images therefore ship
without the Adreno GPU and Iris VPU kernel modules.

feat(debos/rootfs): install additional CamX components
72c0694 
The CamX firmware is already installed in the multimedia variant, but
nothing exposes the cameras to userspace.

Install qti-camera-server, the CamX service which exposes the cameras,
along with the device-specific runtime libraries it needs to drive them
and CamX and FastCV test applications so the stack can be exercised.

The device-specific libraries (camx-server-runtime-all) are restricted
to trixie for now; the package depends on camx-glymur and camx-hamoa
which are not yet built for forky.
