Drop the deprecated drmP.h header file, and trim msm_drv.h to the relevant include files. This resulted in a suprisingly many edits as many files relied on headers included via msm_drv.h. But msm_drv.h is not supposed to carry include files it do not need, so the individual files have to include what extra they needs. v2: - Rebased on top of https://gitlab.freedesktop.org/drm/msm.git msm-next Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Rob Clark <robdclark@gmail.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Jordan Crouse <jcrouse@codeaurora.org> Cc: Jeykumar Sankaran <jsanka@codeaurora.org> Cc: Bruce Wang <bzwang@chromium.org> Cc: Shayenne Moura <shayenneluzmoura@gmail.com> Cc: Mamta Shukla <mamtashukla555@gmail.com> Cc: Jonathan Marek <jonathan@marek.ca> Cc: Carsten Behling <carsten.behling@googlemail.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Paul Kocialkowski <paul.kocialkowski@bootlin.com> Cc: Sibi Sankar <sibis@codeaurora.org> Cc: Todor Tomov <todor.tomov@linaro.org> Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190804065551.GA5211@ravnborg.org

Matthew Ruffell authored
Hisilicon developed hibmc_drm for their arm64 based soc and did not intend for this driver to be used on any other architecture than arm64. Using it on amd64 leads to incorrect video modes being used, making the screen unreadable, forcing users to manually blacklist the module on the kernel command line to use the d-i server installer or any graphical sessions. Make CONFIG_DRM_HISI_HIBMC firmly depend on ARM64 to ensure it is not built for other architectures.

[WHY] value of dchub_ref_clock is decided by dchubbub global timer settings which is programmed by vbios command table disp_init. for multi-GPU case, vbios is posted only for primary GPU. without vbios posted for the secondary GPU, value of dchub_ref_clock is not set properly. this value will affect dcn bandwidth calcuation and cause underflow. user will see screen flicking during driver installation for dual GPU case.

[why] Before a statically allocated PPS data structure, that did get zeroed-out at startup, had been re-used for making packed PPS SDP. With S3 fix, using a non-initialized PPS data structure was introduced, while wrongly assuming it'd get initialized before it's populated. As a consequence 'vbr_enable' and perhaps some other fields are left uninitialized when making packed PPS SDP. This can affect 'simple_422' as well because of the way PPS SDP packing is done (the fields are not masked first, only shifted). The behavior will be different, depending on the content of uninitialized data.
