2018-06-28console/fbcon: Add support for deferred console takeoverHans de Goede5-8/+154
Currently fbcon claims fbdevs as soon as they are registered and takes over the console as soon as the first fbdev gets registered. This behavior is undesirable in cases where a smooth graphical bootup is desired, in such cases we typically want the contents of the framebuffer (typically a vendor logo) to stay in place as is. The current solution for this problem (on embedded systems) is to not enable fbcon. This commit adds a new FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER config option, which when enabled defers fbcon taking over the console from the dummy console until the first text is displayed on the console. Together with the "quiet" kernel commandline option, this allows fbcon to still be used together with a smooth graphical bootup, having it take over the console as soon as e.g. an error message is logged. Note the choice to detect the first console output in the dummycon driver, rather then handling this entirely inside the fbcon code, was made after 2 failed attempts to handle this entirely inside the fbcon code. The fbcon code is woven quite tightly into the console code, making this to only feasible option.

2018-06-25drm: kirin: Remove useless "Scale not support" error messageJohn Stultz1-1/+0
The driver doesn't support scaling, but when an atomic test is done it repeatedly spits out this warning which isn't particularly useful. So just remove the error message.

2018-06-25drm: Make ioctls available for in-kernel clientsNoralf Trønnes4-30/+64
Make ioctl wrappers for functions that will be used by the in-kernel API. The following functions are touched: - drm_mode_create_dumb_ioctl() - drm_mode_destroy_dumb_ioctl() - drm_mode_addfb() - drm_mode_rmfb() Signed-off-by: Noralf Trønnes <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2018-06-25drm: provide management functions for drm_fileDavid Herrmann2-132/+175
Rather than doing drm_file allocation/destruction right in the fops, lets provide separate helpers. This decouples drm_file management from the still-mandatory drm-fops. It prepares for use of drm_file without the fops, both by possible separate fops implementations and APIs (not that I am aware of any such plans), and more importantly from in-kernel use where no real file is available.
