Yet there is no corresponding source provided, and LICENCE.cavium lacks

Cavium has been advertising the appropriate license terms including the existence of GPL in the firmware in our outbox releases. We will update the license terms in LICENCE.cavium in our upstream contribution in collaboration with our legal team. Felix ^ permalink raw reply [flat|nested] 4+ messages in thread

Everything added to linux-firmware.git needs to be safe for Linux distributions to redistribute. (There are some ancient firmware images with unclear licensing, but we don't want to add any more.) My understanding is that GPL v2 requires that commercial distributors either provide the complete and corresponding source alongside the binaries, or include a written offer to provide it later. They *cannot* simply point to your offer to do this (only non-commercial distributors can do that). So the source needs to be published too. Adding the complete Linux kernel source code to linux-firmware.git doesn't seem like a sensible step, so maybe this particular firmware needs to live elsewhere.

Apologies for the delay. We're committed to provide sources for the GPL components of LiquidIO firmware. After Cavium's recent merger with Marvell, we are revisiting our Licensing and expect to share the updated license soon. Since keeping Linux kernel source code in linux-firmware.git doesn't make sense to us too, we're also working internally on identifying the appropriate mechanism to share those sources when requested. That said, it is our opinion that for all practical purposes (for example, distribution of driver + firmware) the firmware binary for LiquidIO adapters should continue to reside in the linux-firmware.git as long as all the prerequisites for sharing the firmware are met. In the case of liquidio_23xx_vsw.bin, this would mean an additional license type in the LICENCE.cavium file for this firmware including a reference to the accompanying sources for the Linux kernel bundled in the firmware. As we understand, there is no precedent in the linux-firmware.git for device firmware that include a Linux kernel so we also request comments from community on the best ways to support the LiquidIO firmware and similar firmwares that may appear in future.
