16:44 <chewitt> howdy folks

16:44 <chewitt> today's dumb Q is .. has anyone attempted to backport panfrost onto Linux 5.4?

16:45 <chewitt> i'm faced with a vendor kernel that needs blobs the vendor is being shy at releasing

16:45 <chewitt> this is for a Mali-G52 variant

16:54 <chewitt> nb: I'm aware that panfrost technically exists in 5.4, but I also expect it to be some way behind newer kernels for performance, stability, compatibility and such

17:11 <robmur01> IIRC there's various DRM core changes that probably stand in the way of that being practical

17:12 <robmur01> (i.e. to *functionally* backport all the panfrost updates you'd probably end up backporting significant chunks of DRM too)

17:34 <chewitt> that was my thinking too

17:34 <chewitt> I'm secretly hoping someone pipes up with 'Yeah, have a look at this repo'

17:34 <chewitt> but I'm not sure I'm that lucky :)

17:35 <rasterman> i think you are electing the "path of pain"\

17:36 <rasterman> or well got stuck with it :)

17:36 <rasterman> non-mainlined code sooner or later becomes a major pain to keep up

17:37 <chewitt> quite, and this is a bsp kernel too, so has 'extras' already

17:37 <chewitt> "vendor feature enhancements" .. or errata in arm-speak

17:38 <rasterman> it may be an easier path to get other things updated and on a path to mainline

17:38 <rasterman> well ok.. that depends on if this is a fire-and-forget bsp

17:39 <rasterman> or they plan to update the kernel eventually anyway thus you're just pushing them to do it a little earlier.
