Contribution Process
====================
Mostly the DRM subsystem works like any other kernel subsystem, see :ref:`the
main process guidelines and documentation <process_index>` for how things work.
Here we just document some of the specialities of the GPU subsystem.
Feature Merge Deadlines
-----------------------
All feature work must be in the linux-next tree by the -rc6 release of the
current release cycle, otherwise they must be postponed and can't reach the next
merge window. All patches must have landed in the drm-next tree by latest -rc7,
but if your branch is not in linux-next then this must have happened by -rc6
already.
After that point only bugfixes (like after the upstream merge window has closed
with the -rc1 release) are allowed. No new platform enabling or new drivers are
allowed.
This means that there's a blackout-period of about one month where feature work
can't be merged. The recommended way to deal with that is having a -next tree
that's always open, but making sure to not feed it into linux-next during the
blackout period. As an example, drm-misc works like that.

Better manual-upload support for atomic
---------------------------------------
This would be especially useful for tinydrm:
- Add a struct drm_rect dirty_clip to drm_crtc_state. When duplicating the
crtc state, clear that to the max values, x/y = 0 and w/h = MAX_INT, in
__drm_atomic_helper_crtc_duplicate_state().
- Move tinydrm_merge_clips into drm_framebuffer.c, dropping the tinydrm_
prefix ofc and using drm_fb_. drm_framebuffer.c makes sense since this
is a function useful to implement the fb->dirty function.
- Create a new drm_fb_dirty function which does essentially what e.g.
mipi_dbi_fb_dirty does. You can use e.g. drm_atomic_helper_update_plane as the
template. But instead of doing a simple full-screen plane update, this new
helper also sets crtc_state->dirty_clip to the right coordinates. And of
course it needs to check whether the fb is actually active (and maybe where),
so there's some book-keeping involved. There's also some good fun involved in
scaling things appropriately. For that case we might simply give up and
declare the entire area covered by the plane as dirty.

Clean up the debugfs support
----------------------------
There's a bunch of issues with it:
- The drm_info_list ->show() function doesn't even bother to cast to the drm
structure for you. This is lazy.
- We probably want to have some support for debugfs files on crtc/connectors and
maybe other kms objects directly in core. There's even drm_print support in
the funcs for these objects to dump kms state, so it's all there. And then the
->show() functions should obviously give you a pointer to the right object.
- The drm_info_list stuff is centered on drm_minor instead of drm_device. For
anything we want to print drm_device (or maybe drm_file) is the right thing.
- The drm_driver->debugfs_init hooks we have is just an artifact of the old
midlayered load sequence. DRM debugfs should work more like sysfs, where you
can create properties/files for an object anytime you want, and the core
takes care of publishing/unpuplishing all the files at register/unregister
time. Drivers shouldn't need to worry about these technicalities, and fixing
this (together with the drm_minor->drm_device move) would allow us to remove
debugfs_init.

Driver Specific

tinydrm
-------
Tinydrm is the helper driver for really simple fb drivers. The goal is to make
those drivers as simple as possible, so lots of room for refactoring:
- backlight helpers, probably best to put them into a new drm_backlight.c.
This is because drivers/video is de-facto unmaintained. We could also
move drivers/video/backlight to drivers/gpu/backlight and take it all
over within drm-misc, but that's more work.
- spi helpers, probably best put into spi core/helper code. Thierry said
the spi maintainer is fast&reactive, so shouldn't be a big issue.
- extract the mipi-dbi helper (well, the non-tinydrm specific parts at
least) into a separate helper, like we have for mipi-dsi already. Or follow
one of the ideas for having a shared dsi/dbi helper, abstracting away the
transport details more.
- tinydrm_lastclose could be drm_fb_helper_lastclose. Only thing we need
for that is to store the drm_fb_helper pointer somewhere in
drm_device->mode_config. And then we could roll that out to all the
drivers.
- tinydrm_gem_cma_prime_import_sg_table should probably go into the cma
helpers, as a _vmapped variant (since not every driver needs the vmap).
And tinydrm_gem_cma_free_object could the be merged into
drm_gem_cma_free_object().
- tinydrm_fb_create we could move into drm_simple_pipe, only need to add
the fb_create hook to drm_simple_pipe_funcs, which would again simplify a
bunch of things (since it gives you a one-stop vfunc for simple drivers).
- Quick aside: The unregister devm stuff is kinda getting the lifetimes of
a drm_device wrong. Doesn't matter, since everyone else gets it wrong
too :-)
- With the fbdev pointer in dev->mode_config we could also make
suspend/resume helpers entirely generic, at least if we add a
dev->mode_config.suspend_state. We could even provide a generic pm_ops
structure with those.
- also rework the drm_framebuffer_funcs->dirty hook wire-up, see above.
