Linux kernel source tree

We need to block DC6 entry in case of Panel Replay as enabling VBI doesn't prevent DC6 in case of Panel Replay. This causes problems if user-space is polling for vblank events. Fix this by setting target DC state as DC_STATE_EN_UPTO_DC5 when both source and sink are supporting eDP Panel Replay and VBI is enabled. v4: - s/vblank_work/vblank_dc_work/ - changed type of block_dc_for_vblank to bool v3: - do flush_work for vblank_work on intel_crtc_vblank_off - no need to use READ_ONCE in bdw_enable_vblank - check crtc->block_dc_for_vblank in bdw_disable_vblank as well - move adding block_dc_for_vblank into this patch v2: - use READ_ONCE in intel_display_vblank_work - use DC_STATE_DISABLE instead of DC_STATE_EN_UPTO_DC6 - use intel_crtc->block_dc6_needed Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/2296 Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240920062340.1333777-3-jouni.hogander@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 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.
