drm/amdgpu: add a dev_pm_ops prepare callback (v2)
as per:
https://www.kernel.org/doc/html/latest/driver-api/pm/devices.html
The prepare callback is required to support the DPM_FLAG_SMART_SUSPEND
driver flag. This allows runtime pm to auto complete when the
system goes into suspend avoiding a wake up on suspend and on resume.
Apply this for hybrid gfx and BOCO systems where d3cold is
provided by the ACPI platform.

drm/print: Fixup DRM_DEBUG_KMS_RATELIMITED()
Since we're about to move drm_dp_helper.c over to drm_dbg_*(), we'll want
to make sure that we can also add ratelimited versions of these macros in
order to retain some of the previous debugging output behavior we had.
However, as I was preparing to do this I noticed that the current
rate limited macros we have are kind of bogus. It looks like when I wrote
these, I didn't notice that we'd always be calling __ratelimit() even if
the debugging message we'd be printing would normally be filtered out due
to the relevant DRM debugging category being disabled.
So, let's fix this by making sure to check drm_debug_enabled() in our
ratelimited macros before calling __ratelimit(), and start using
drm_dev_printk() in order to print debugging messages since that will save
us from doing a redundant drm_debug_enabled() check. And while we're at it,
let's move the code for this into another macro that we can reuse for
defining new ratelimited DRM debug macros more easily.

drm/vblank: Do not store a new vblank timestamp in drm_vblank_restore()
drm_vblank_restore() exists because certain power saving states
can clobber the hardware frame counter. The way it does this is
by guesstimating how many frames were missed purely based on
the difference between the last stored timestamp vs. a newly
sampled timestamp.
If we should call this function before a full frame has
elapsed since we sampled the last timestamp we would end up
with a possibly slightly different timestamp value for the
same frame. Currently we will happily overwrite the already
stored timestamp for the frame with the new value. This
could cause userspace to observe two different timestamps
for the same frame (and the timestamp could even go
backwards depending on how much error we introduce when
correcting the timestamp based on the scanout position).
To avoid that let's not update the stored timestamp at all,
and instead we just fix up the last recorded hw vblank counter
value such that the already stored timestamp/seq number will
match. Thus the next time a vblank irq happens it will calculate
the correct diff between the current and stored hw vblank counter
values.
Sidenote: Another possible idea that came to mind would be to
do this correction only if the power really was removed since
the last time we sampled the hw frame counter. But to do that
we would need a robust way to detect when it has occurred. Some
possibilities could involve some kind of hardare power well
transition counter, or potentially we could store a magic value
in a scratch register that lives in the same power well. But
I'm not sure either of those exist, so would need an actual
investigation to find out. All of that is very hardware specific
of course, so would have to be done in the driver code.

In addition, the field 'conn' is removed from the mtk_hdmi struct since
mtk_hdmi don't create a connector. It is replaced with a pointer
'curr_conn' that points to the current connector which can be access
through the global state.
This patch is inspired by a similar patch for bridge/synopsys/dw-hdmi.c:
commit
ec971aaa6775
("drm: bridge: dw-hdmi: Make connector creation optional")
But with the difference that in mtk-hdmi only the option of not creating
a connector is supported.

The bridge operation '.enable' and the audio cb '.get_eld'

the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR and then we will
not have direct access to the connector.
The atomic version '.atomic_enable' allows accessing the

drm/displayid: add new displayid section/block iterators
Iterating DisplayID blocks across sections (in EDID extensions) is
unnecessarily complicated for the caller. Implement DisplayID iterators
to go through all blocks in all sections.
Usage example:
const struct displayid_block *block;
struct displayid_iter iter;
displayid_iter_edid_begin(edid, &iter);
displayid_iter_for_each(block, &iter) {
/* operate on block */
}
displayid_iter_end(&iter);
When DisplayID is stored in EDID extensions, the DisplayID sections map
to extensions as described in VESA DisplayID v1.3 Appendix B: DisplayID
as an EDID Extension. This is implemented here.
When DisplayID is stored in its dedicated DDC device 0xA4, according to
VESA E-DDC v1.3, different rules apply for the structure. This is not
implemented here, as we don't currently use it, but the idea is you'd
have a different call for beginning the iteration, for example simply:
displayid_iter_begin(displayid, &iter);
instead of displayid_iter_edid_begin(), and everything else would be
hidden away in the iterator functions.

drm/i915: Unify the FB and plane state view information into one struct
To allow the simplification of FB/plane view computation in the
follow-up patches, unify the corresponding state in the
intel_framebuffer and intel_plane_state structs into a new intel_fb_view
struct.
This adds some overhead to intel_framebuffer as the rotated view will
have now space for 4 color planes instead of the required 2 and it'll
also contain the unused offset for each color_plane info. Imo this is an
acceptable trade-off to get a simplified way of the remap computation.
Use the new intel_fb_view struct for the FB normal view as well, so (in
the follow-up patches) we can remove the special casing for normal view
calculation wrt. the calculation of remapped/rotated views. This also
adds an overhead to the intel_framebuffer struct, as the gtt remap info
and per-color plane offset/pitch is not required for the normal view,
but imo this is an acceptable trade-off as above. The per-color plane
pitch filed will be used by a follow-up patch, so we can retrieve the
pitch for each view in the same way.
No functional changes in this patch.
v2:
- Make the patch have _no functional change_.
(fix skl_check_nv12_aux_surface() and skl_check_main_surface()).

Factor out to a new function the logic to calculate an FB plane's

Instead of using intel_remapped_plane_info, which is related only to
remapping, add a helper to get the tile pitch and rows for an FB plane,
so these helpers can be used both by the normal size calculation and the
remapping code.
Also add a new fb_plane_view_dims struct in which we can pass around the

- amdgpu: Add a new INFO ioctl interface to query video capabilities
rather than hardcoding them in userspace. This allows us to provide
fine grained asic capabilities (e.g., if a particular part is
bandwidth limited, we can limit the capabilities). Proposed userspace:

Danvet: A bunch of conflicts all over, but it seems to compile ... I
did put the call to dc_allow_idle_optimizations() on a single line
since it looked a bit too jarring to be left alone.

drm/i915: add gem/gt TODO
We've discussed a bit how to get the gem/gt team better integrated
and collaborate more with the wider community and agreed to the
following:
- all gem/gt patches are reviewed on dri-devel for now. That's
overkill, but in the past there was definitely too little of that.
- i915-gem folks are encouraged to cross review core patches from
other teams
- big features (especially uapi changes) need to be discussed in an
rfc patch that documents the interface and big picture design,
before we get lost in the details of the code
- Also a rough TODO (can be refined as we go ofc) to get gem/gt back
on track, like we've e.g. done with DAL/DC to get that in shape.
v2:
- add dma_fence annotations (Dave)
- tasklet helpers (Jani on irc)
There was also a discussion about moving these into gitlab issues, or
gitlab issues as additional discussion place at least. For now it's
just the TODO file
