Changes in v2: - Remove unused definitions - Improve file names - Improve code separation - Remove unnecessary formats Changes in v3: - Adds drm_crtc_helper_funcs with a simple atomic_check - Adds extra hooks for drm_connector_funcs hooks (reset, atomic_duplicate_state, atomic_destroy_state) - Adds drm_connector_helper_funcs - Adds drm_plane_helper_funcs - Changes in the commit messages Rodrigo Siqueira (3): drm/vkms: Add mode_config initialization drm/vkms: Add basic CRTC initialization drm/vkms: Add extra information about vkms drivers/gpu/drm/Kconfig | 8 +- drivers/gpu/drm/vkms/Makefile | 2 +- drivers/gpu/drm/vkms/vkms_crtc.c | 47 ++++++++++++ drivers/gpu/drm/vkms/vkms_drv.c | 55 +++++--------- drivers/gpu/drm/vkms/vkms_drv.h | 33 +++++++- drivers/gpu/drm/vkms/vkms_output.c | 118 +++++++++++++++++++++++++++++ drivers/gpu/drm/vkms/vkms_plane.c | 62 +++++++++++++++ 7 files changed, 285 insertions(+), 40 deletions(-) create mode 100644 drivers/gpu/drm/vkms/vkms_crtc.c create mode 100644 drivers/gpu/drm/vkms/vkms_output.c create mode 100644 drivers/gpu/drm/vkms/vkms_plane.c -- 2.17.0 _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 12+ messages in thread

For each entry there's also a link to the full license text, etc. To provide some meat for my personal views/suggestion: - 2.0-only is narrowly scoped, while 2.0-or-later allows using any future, _yet to be written_, version of the license - MIT historically all of DRM (and graphics stack as a whole) has been MIT so that others - BSD, Solaris etc could reuse it. But as I said, it's not my call.

Wrt duplicate/destroy state, those are mandatory. I think it'd be good to have checks for those in the drm_*_init functions, but only for atomic drivers. You can use drm_drv_uses_atomic_modeset() and WARN_ON(). There's a bunch of examples already for checking for this stuff, see e.g. dma_fence_init(). > - Adds drm_connector_helper_funcs > - Adds drm_plane_helper_funcs Same here, would be good to add WARN_ON to the relevant _init() functions to make sure all the mandatory stuff is there to begin with. Since Rodrigo has typed the fixes to vkms already, could you Haneen look into adding these checks to the core drm core?

Yes, but drm_mode_config_reset is a helper, and not mandatory. Most drivers use that to initialize the software state structures, but e.g. i915 reads out the actual hardware state, and uses that to reconstruct the software state. This allows for smooth take over of the boot loader screen state, avoiding flickering. That's why the ->reset hooks aren't mandatory, but duplicate/destroy hooks are. > > > Wrt duplicate/destroy state, those are mandatory.
