PIPE_MBUS_DBOX_CTL was only being programmed when a pipe is being enabled but that could potentially cause issues as it could have mismatching values while pipes are being enabled. So here moving the PIPE_MBUS_DBOX_CTL programming of all pipes to be executed before the function that enables all pipes, leaving all pipes with a matching A_CREDIT value. While at it, also moving it to intel_pm.c as we are trying to reduce the gigantic size of intel_display.c and intel_pm.c have other MBUS programing sequences. v2: - do not program PIPE_MBUS_DBOX_CTL if pipe will not be active or when it do not needs modeset - remove the checks to wait a vblank v3: - checking if dbuf state is present in state before using it v4: - removing redundant checks - calling intel_atomic_get_new_dbuf_state instead of intel_atomic_get_dbuf_state BSpec: 49213 BSpec: 50343 Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220330155724.255226-3-jose.souza@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.
