Adaptive Sync is a VESA feature so add a DRM core helper to parse the EDID's detailed descritors to obtain the adaptive sync monitor range. Store this info as part fo drm_display_info so it can be used across all drivers. This part of the code is stripped out of amdgpu's function amdgpu_dm_update_freesync_caps() to make it generic and be used across all DRM drivers v6: * Call it monitor_range (Ville) v5: * Use the renamed flags v4: * Use is_display_descriptor() (Ville) * Name the monitor range flags (Ville) v3: * Remove the edid parsing restriction for just DP (Nicholas) * Use drm_for_each_detailed_block (Ville) * Make the drm_get_adaptive_sync_range function static (Harry, Jani) v2: * Change vmin and vmax to use u8 (Ville) * Dont store pixel clock since that is just a max dotclock and not related to VRR mode (Manasi) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Clinton A Taylor <clinton.a.taylor@intel.com> Cc: Kazlauskas Nicholas <Nicholas.Kazlauskas@amd.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200310231651.13841-2-manasi.d.navare@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.
