============== Introduction ============== The purpose of this series is to add the driver for video codec hw embedded in the Mediatek's MT8173 SoCs. Mediatek Video Codec is able to handle video decoding of in a range of formats. This patch series add Mediatek block format V4L2_PIX_FMT_MT21, the decoder driver will decoded bitstream to V4L2_PIX_FMT_MT21 format. This patch series rely on MTK VPU driver in patch series "Add MT8173 Video Encoder Driver and VPU Driver"[1] and patch "CHROMIUM: v4l: Add V4L2_PIX_FMT_VP9 definition"[2] for VP9 support. Mediatek Video Decoder driver rely on VPU driver to load, communicate with VPU. Internally the driver uses videobuf2 framework and MTK IOMMU and MTK SMI both have been merged in v4.6-rc1. [1]https://patchwork.linuxtv.org/patch/33734/ [2]https://chromium-review.googlesource.com/#/c/245241/Hmm... I'm not seeing the firmware for this driver at the linux-firmware tree: https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/log/ Nor I'm seeing any pull request for them. Did you send it? I'll only merge the driver upstream after seeing such pull request.Sorry, I am not familiar with how to upstream firmware. Do you mean we need to upstream vpu firmware first before merge encoder driver upstream?
Please look at this page: https://linuxtv.org/wiki/index.php/Development:_How_to_submit_patches#Firmware_submission The information here can also be useful: https://www.kernel.org/doc/readme/firmware-README.AddingFirmware In summary, you need to provide redistribution rights for the firmware blob. You can either submit it to me or directly to linux-firmware. In the latter, please c/c me on such patch. Thanks! Mauro
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-firmware at kernel.org and also cc: to related mailing lists." How we made a git pull request to linux-firmware at kernel.org? How we find out related mailing lists? best regards, Tiffanyquoted
Mauro, are you confusing the decoder and encoder driver? I haven't thoroughly reviewed the decoder driver yet, so there is no pull request for the decoder driver. The only pull request I made was for the encoder driver. Regards, Hans
