Add helpers to program the 3D LUT registers and arm them. LUT_3D_READY in LUT_3D_CLT is cleared off by the HW once the LUT buffer is loaded into it's internal working RAM. So by the time we try to load/commit new values, we expect it to be cleared off. If not, log an error and return without writing new values. Do it only when writing with MMIO. There is no way to read register within DSB execution. v2: - Add information regarding LUT_3D_READY to commit message (Jani) - Log error instead of a drm_warn and return without committing changes if 3DLUT HW is not ready to accept new values. - Refactor intel_color_crtc_has_3dlut() Also remove Gen10 check (Suraj) v3: - Addressed review comments (Suraj) Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Signed-off-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patch.msgid.link/20251203085211.3663374-15-uma.shankar@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com> |

README
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 reStructuredText 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.
