We eagerly await to see if the AMD ISP4 driver will be ready for mainlining in the imminent Linux v6.19 merge window but it’s getting down to the wire and thus looking less likely it will make it unless action is taken in the coming days. Today though a sixth version of this AMD ISP4 image signal processor driver was posted for this last piece of the puzzle in enabling the web camera on the HP ZBook Ultra G1a Strix Halo laptop as well as future Ryzen high-end laptops.

Getting this AMD ISP4 driver to the mainline kernel is all that’s needed for getting the HP ZBook Ultra G1a laptop’s web camera working nicely under Linux – complete with working offloading unlike the latest Intel IPU-enabled web cameras relying on the CPU-based “Soft ISP” when relying on the open-source user-space software. For now the ISP4 IP is used by just the high-end HP ZBook Ultra G1a Ryzen AI Max+ PRO laptops but it’s expected to be used by more next-generation AMD Ryzen laptops for a leading web camera experience. This is the last piece as well for making a nice well-rounded Linux experience for the HP ZBook Ultra G1a with all of the other hardware support in great shape – even LVFS/Fwupd support!
