Recently, we added support for an experimental feature named Freesync
video; for more details on that, refer to:commit 6f59f229f8ed ("drm/amd/display: Skip modeset for front porch change")
commit d10cd527f5e5 ("drm/amd/display: Add freesync video modes based on preferred modes")
commit 0eb1af2e8205 ("drm/amd/display: Add module parameter for freesync video mode")Nevertheless, we did not document it in detail in our driver. This
commit introduces a kernel-doc and expands the module parameter

Reading out of write-combining mapped memory is typically very slow
since the CPU doesn't prefetch. However some archs have special
instructions to do this.So add a best-effort memcpy_from_wc taking dma-buf-map pointer
arguments that attempts to use a fast prefetching memcpy and
otherwise falls back to ordinary memcopies, taking the iomem tagging
into account.The code is largely copied from i915_memcpy_from_wc.

Platform devices might operate on firmware framebuffers, such as VESA
or EFI. Before a native driver for the graphics hardware can take over
the device, it has to remove any platform driver that operates on the
firmware framebuffer. Aperture helpers provide the infrastructure for
native drivers to remove the generic ones.For now, this only concerns generic fbdev drivers. Code for removing
these is provided by drm_fb_helper_remove_conflicting_framebuffers() et
al. Simply wrap these functions for now. At a later point, code can be
added for generic DRM drivers to acquire firmware framebuffers.v2:

USB devices cannot perform DMA and hence have no dma_mask set in their
device structure. Therefore importing dmabuf into a USB-based driver
fails, which breaks joining and mirroring of display in X11.For USB devices, pick the associated USB controller as attachment device.
This allows the DRM import helpers to perform the DMA setup. If the DMA
controller does not support DMA transfers, we're out of luck and cannot
import. Our current USB-based DRM drivers don't use DMA, so the actual
DMA device is not important.Tested by joining/mirroring displays of udl and radeon under Gnome/X11.

* release dmadev if device initialization fails (Noralf)
* fix commit description (Noralf)

* fix use-before-init bug in gm12u320 (Dan)

Only planes' prepare_fb and cleanup_fb, and encoders' atomic_check and
atomic_mode_set hooks remain with an object state and not the global
drm_atomic_state.prepare_fb and cleanup_fb operate by design on a given state and
depending on the calling site can operate on either the old or new
state, so it doesn't really make much sense to convert them.The encoders' atomic_check and atomic_mode_set operate on the CRTC and
connector state connected to them since encoders don't have a state of
their own. Without those state pointers, we would need to get the CRTC
through the drm_connector_state crtc pointer.However, in order to get the drm_connector_state pointer, we would need
to get the connector itself and while usually we have a single connector
connected to the encoder, we can't really get it from the encoder at
the moment since it could be behind any number of bridges.While this could be addressed by (for example) listing all the
connectors and finding the one that has the encoder as its source, it
feels like an unnecessary rework for something that is slowly getting
replaced by bridges.Since all the users that matter have been converted, let's remove the
TODO item.Acked-by: Daniel Vetter

Several drivers use GEM buffer objects as shadow buffers for the actual
framebuffer memory. Right now, drivers do these vmap operations in their
commit tail, which is actually not allowed by the locking rules for
the dma-buf reservation lock. The involved BO has to be vmapped in the
plane's prepare_fb callback and vunmapped in cleanup_fb.This patch introduces atomic helpers for such shadow planes. Plane
functions manage the plane state for shadow planes. The provided
implementations for prepare_fb and cleanup_fb vmap and vunmap all BOs of
struct drm_plane_state.fb. The mappings are afterwards available in the
plane's commit-tail functions.For now, all rsp drivers use the simple KMS helpers, so we add the plane
callbacks and wrappers for simple KMS. The internal plane functions can
later be exported as needed.v3:

Replace the lkml.org links with lore to better use a single source

It doesn't seem like drm.h docs are included anywhere. Render them next
to drm_mode.h, under the "Userspace API Structures" section.This also allows references to e.g. DRM_CAP_* to be properly linkified
elsewhere in our docs.Signed-off-by: Simon Ser
