Hello, I've been looking onto fixing the ITP bug ([1]) for Qualcomm Hexagon DSP binaries ([2]). In short, these are the binaries that are loaded onto the DSP by the userspace helpers through the Linux fastrpc driver (as supported upstream). The preview packages are available at [3].
During the review Robbie asked several important questions, the most important are the following (for which I'd look for guidance): Relationship with firmware-nonfree. ----------------------------------------------- The binaries for the DSP must exactly match the version of DSP firmware (provided by the firmware-qcom-soc package). For now I've ended up with the simplest way: publish a new release each time linux-firmware is released. This way distributions can simply make tight version dependency from hexagon-dsp packages onto corresponding firmware-qcom-soc, making sure that they are upgraded in lock. Rabbie pointed out that this might cause issues for firmware-nonfree propagation and unnecessary package downloads for Hexagon packages. An alternative would be to make firmware-qcom-soc provide virtual packages which correspond to the actual versions of DSP firmware provided by the package and use those virtual packages in hexagon-dsp-libs package dependencies. However this would incur additional scripting to parse firmware-nonfree blobs (or WHENCE) for version info and putting that into the debian/control. Any other proposals would also be appreciated. Package versions ------------------------ Following the linux-firmware we have adopted date as a version for the releases of the tarballs. Lintian suggests using 0~ prefix for the Debian version in such a case, but I'm not sure if that suggestion applies here. Could you possibly comment on it? Filesystem structure --------------------------- During the development of the hexagonrpcd project we had several discussions regarding placement of these DSP binaries. We settled on placing them under /usr/share/qcom/, having a subdir per each platform. Does that sound good enough?
