All non-legacy users of VBLANK functions in struct drm_driver have been converted to use the respective interfaces in struct drm_crtc_funcs. The remaining users of VBLANK callbacks in struct drm_driver are legacy drivers with userspace modesetting. All users of struct drm_driver.get_scanout_position() have been converted to the respective CRTC helper function. Remove the callback from struct drm_driver. There are no users left of get_vblank_timestamp(), so the callback is being removed. The other VBLANK callbacks are being moved to the legacy section at the end of struct drm_driver. Also removed is drm_calc_vbltimestamp_from_scanoutpos(). Callers of this function have been converted to use the CRTC instead. v4: * more readable code for setting high_prec (Ville, Jani) v2: * merge with removal of struct drm_driver.get_scanout_position() * remove drm_calc_vbltimestamp_from_scanoutpos() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Tested-by: Yannick Fertré <yannick.fertre@st.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200123135943.24140-22-tzimmermann@suse.de
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
