I currently have a prototype board based on AM5728 that is mostly working, using branch ti/ti-linux-4.19.y of the TI kernel [0]. Now I need some non-TI-specific kernel features that appeared in mainline 5.10, so I tried to move to branch ti/ti-linux-5.10.y. But many components that I am using on the 4.19 branch seem absent on the 5.10 branch, including VIDEO_TI_VIP, DRM_OMAP_WB and DRM_OMAP_CONNECTOR_HDMI. BTW they are not present even in mainline Linux. Are this drivers still absent and in progress of being added to ti/ti-linux-5.10.y, or are they present in a different form that I have been unable to find? Assuming they still have to be added, is there an estimate timing for their availability on the 5.10 branch?

In public, No - Note: even though the git repo is public, and internally we attempt to follow the same upstream rules, at the end, it is still a vendor kernel :(. But, rest assure that internally, we know precisely where we are and we are tracking towards completion. While linux-omap is a public list, it might be better to answer vendor kernel questions in the context of e2e.ti.com (The TI forums - there are folks closely monitoring those and actively engaging to help customers out and will be better positioned to answer your specific queries). Do feel free to reach out to me on irc freenode.net #linux-omap etc if you'd need anything specific to help with. We usually prefer linux-omap mailing list to stick with upstream discussions, one off vendor kernel discussions do take place from time to time, however, most of our TI support folks are better equipped to answer questions on TI forums. The above "officialdom statement" said, we do actively encourage our community (which we include ourselves and TI customers as well) to participate in making upstream kernel complete and point out anything we may have overlooked (yep, we are human) so that overall what vendor kernel does or does'nt do should be inconsequential in the longer term for the community and products derived from community. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D ^ permalink raw reply [flat|nested] 9+ messages in thread

Thanks for taking time to provide extra explanations! I'll be using the channels you suggested for more specific questions. IIRC many years ago there used to be a web page for the OMAP 3530 (on some TI wiki?) listing SoC devices and their driver status, with a green "OK" for implemented drivers, yellow for work in progress or similar. It was very useful to know from the beginning whether a driver was supposed to exist and work on a given branch, to avoid grepping and searching to even know whether it exists. It would be great to have something like that these days. My 2c... -- Luca ^ permalink raw reply [flat|nested] 9+ messages in thread

Actually I still haven't tackled HDMI on ti-linux-5.10.y, I only found it by comparing the .config from the working 4.19 branch and from 5.10 and noticed the config option has disappeared. My current problem is that omapdrm does not populate /dev/fb0 (perhaps due to a similar reason) and the VIP driver apparently just not present on the 5.10.y branch.

Well HDMI should be working, at least it was when I last tested with omap2plus_defconfig. Maybe you're missing CONFIG_FB=y ? No idea about VIP driver though.

Maybe you're missing CONFIG_FB=y ? Thanks for the hints! CONFIG_FB is y, so it must be something else. Maybe I have to update my DT?
