Hi Javier, thanks for this patch. Acked-by: Thomas Zimmermann <tzimmermann@xxxxxxx> Find some ideas for consideration below. Am 27.01.22 um 09:20 schrieb Javier Martinez Canillas:
The Linux DRM subsystem supports complex graphics devices and it could be quite overwhelming for newcomers to learn about the subsystem's internals. There are lots of useful talks, slides and articles available that can be used to get familiar with the needed concepts and ease the learning curve. Add a section to the intro that contains these DRM introductory materials.

It sounds a bit intimdating to me. Can we give it a positive spin?IMHO we could add a separate section that talks about complexity and provides guidelines about how to deal with it: trivial HW? use simple pipe; dedicated VRAM? try TTM; awkward color formats? see drm_format_helper.c
Best regards Thomas
+ +To shallow the learning curve, this section contains a list of presentations +and documents that can be used to learn about DRM/KMS and graphics in general. + +The list is sorted in reverse chronological order, to keep the most up-to-date +material at the top.
