drm/i915: Simplify CCS and UV plane alignment handling
We can handle the surface alignment of CCS and UV color planes for all
modifiers at one place, so do this. An AUX color plane can be a CCS or a
UV plane, use only the more specific query functions and remove
is_aux_plane() becoming redundant.
While at it add a TODO for linear UV color plane alignments. The spec
requires this to be stride-in-bytes * 64 on all platforms, whereas the
driver uses an alignment of 4k for gen<12 and 256k for gen>=12 for
linear UV planes.
v2:
- Restore previous alignment for linear UV surfaces.

drm/i915: Fix modesetting in case of unexpected AUX timeouts
In case AUX failures happen unexpectedly during a modeset, the driver
should still complete the modeset. In particular the driver should
perform the link training sequence steps even in case of an AUX failure,
as this sequence also includes port initialization steps. Not doing that
can leave the port/pipe in a broken state and lead for instance to a
flip done timeout.
Fix this by continuing with link training (in a no-LTTPR mode) if the
DPRX DPCD readout failed for some reason at the beginning of link
training. After a successful connector detection we already have the
DPCD read out and cached, so the failed repeated read for it should not
cause a problem. Note that a partial AUX read could in theory partly
overwrite the cached DPCD (and return error) but this overwrite should
not happen if the returned values are corrupted (due to a timeout or
some other IO error).
Kudos to Ville to root cause the problem.

drm/i915/display: rename display version macros
While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:
1) Why is the == comparison special that deserves a separate
macro instead of just getting the version and comparing directly
like is done for >, >=, <=?
2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
brevity. If we remove the current users of IS_DISPLAY_VER(), we
could actually repurpose it for a range check
With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.
So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:
@@ expression dev_priv, E1; @@
- !IS_DISPLAY_VER(dev_priv, E1)
+ DISPLAY_VER(dev_priv) != E1
@@ expression dev_priv, E1; @@
- IS_DISPLAY_VER(dev_priv, E1)
+ DISPLAY_VER(dev_priv) == E1
@@ expression dev_priv, from, until; @@
- IS_DISPLAY_RANGE(dev_priv, from, until)
+ IS_DISPLAY_VER(dev_priv, from, until)

drm/i915: rename display.version to display.ver
The macro we use to check is called DISPLAY_VER(). While using this
macro and the new ones being added in following changes I made the
mistake multiple times when mixing both "ver" and "version". Although
it's usually better to prefer the complete name, the shorhand
DISPLAY_VER() / GRAPHICS_VER / MEDIA_VER are clear and cause less
visual polution.
Another issue is when copying the variable to other places.
"display.version" would be copied to a "display_version" variable which
is long and would make people abbreviate as "version", or "display_ver".
In the first case it's not always clear what version refers to, and in
the second case it just hints it should be the name in the first place.
So, in the same way use used "gen" rather than "generation", use "ver"
instead of "version".

drm/i915/display/vlv_dsi: Do not skip panel_pwr_cycle_delay when disabling the panel
After the recently added commit
fe0f1e3bfdfe ("drm/i915: Shut down
displays gracefully on reboot"), the DSI panel on a Cherry Trail based
Predia Basic tablet would no longer properly light up after reboot.
I've managed to reproduce this without rebooting by doing:
chvt 3; echo 1 > /sys/class/graphics/fb0/blank;\
echo 0 > /sys/class/graphics/fb0/blank
Which rapidly turns the panel off and back on again.
The vlv_dsi.c code uses an intel_dsi_msleep() helper for the various delays
used for panel on/off, since starting with MIPI-sequences version >= 3 the
delays are already included inside the MIPI-sequences.
The problems exposed by the "Shut down displays gracefully on reboot"
change, show that using this helper for the panel_pwr_cycle_delay is
not the right thing to do. This has not been noticed until now because
normally the panel never is cycled off and directly on again in quick
succession.
Change the msleep for the panel_pwr_cycle_delay to a normal msleep()
call to avoid the panel staying black after a quick off + on cycle.

seem to work.
Note though I'm not entirely clear on this - on one of the machines where
this issue was observed, I also noticed that we appeared to be rejecting
the VBT defined backlight frequency in
intel_dp_aux_vesa_calc_max_backlight(). It's noted in this function that:
/* Use highest possible value of Pn for more granularity of brightness
* adjustment while satifying the conditions below.
* ...
* - FxP is within 25% of desired value.
* Note: 25% is arbitrary value and may need some tweak.

So it's possible that this value might just need to be tweaked, but for now
let's just disable the VESA backlight interface unless it's specified in
the VBT just to be safe. We might be able to try enabling this again by
default in the future.

drm/i915: Fix invalid access to ACPI _DSM objects
intel_dsm_platform_mux_info() tries to parse the ACPI package data
from _DSM for the debug information, but it assumes the fixed format
without checking what values are stored in the elements actually.
When an unexpected value is returned from BIOS, it may lead to GPF or
NULL dereference, as reported recently.
Add the checks of the contents in the returned values and skip the
values for invalid cases.

drm/mediatek: Don't support hdmi connector creation
commit
f01195148967 ("drm/mediatek: mtk_dpi: Create connector for bridges")
broke the display support for elm device since mtk_dpi calls
drm_bridge_attach with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR
while mtk_hdmi does not yet support this flag.
Fix this by accepting DRM_BRIDGE_ATTACH_NO_CONNECTOR in bridge attachment.
Implement the drm_bridge_funcs .detect() and .get_edid() operations, and
call drm_bridge_hpd_notify() to report HPD. This provides the
necessary API to support disabling connector creation.
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.

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.

An upcoming platform has a restriction that the FB stride must be
power-of-two aligned. To support framebuffer layouts that are not in
this layout add a logic that pads the tile rows to the POT aligned size.
The HW won't read the padding PTEs, so these don't have to point to an
allocated address, or even have their valid flag set. So use a NULL PTE
instead for instance the scratch page, which is simple and keeps the SG
table compact.
v2:
- Simplify plane_view_dst_stride(). (Ville)
- Pass pitch_tiles as unsigned int.
v3:
- Drop unintentional s/plane_state->rotation/plane_config->rotation/
change.

drm/i915: Simplify copying the FB view state to the plane state
Instead of copying separately the GTT remapped and color plane view info
from the FB to the plane state, do this by copying the whole
intel_fb_view struct. For this we make sure the FB view state is fully
inited (that is also including the view type) already during FB
creation, so this init is not required during atomic check time. This
also means the we don't need to reset the unused color plane info during
atomic check, as these are already reset during FB creation.
I noticed that initial FBs will only work atm if they are page aligned
(which BIOS most probably always ensures), but add a comment to sanitize
this part once. Also we won't disable the plane if
get_initial_plane_config() failed for some reason (for instance due to
unsupported rotation), add a TODO: comment for this too.

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_.
