Do you mean we need to upstream vpu firmware first before merge encoder driver upstream? In https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/README, it mentions that "To submit firmware to this repository, please send either a git binary diff or preferably a git pull request to: linux-firmw...@kernel.org and also cc: to related mailing lists." How we made a git pull request to linux-firmw...@kernel.org? How we find out related mailing lists? best regards, Tiffany > Mauro, are you confusing the decoder and encoder driver?
