Replace the use of mode->private_flags with a truly private bitmaks in our own crtc state. We also need a copy in the crtc itself so the vblank code can get at it. We already have scanline_offset in there for a similar reason, as well as the vblank->hwmode which is assigned via drm_calc_timestamping_constants(). Fortunately we now have a nice place for doing the crtc_state->crtc copy in intel_crtc_update_active_timings() which gets called both for modesets and init/resume readout. The one slightly iffy spot is the INHERITED flag which we want to preserve until userspace/fb_helper does the first proper commit after actually calling .detecti() on the connectors. Otherwise we don't have the full sink capabilities (audio,infoframes,etc.) when .compute_config() gets called and thus we will fail to enable those features when the first userspace commit happens. The only internal commit we do prior to that should be from intel_initial_commit() and there we can simply preserve the INHERITED flag from the readout. v2: Deal with INHERITED in sanitize_watermarks() as well CC: Sam Ravnborg <sam@ravnborg.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200429103904.11727-1-ville.syrjala@linux.intel.com
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.
