drm/i915: Remove erroneous i915_is_ggtt check for I915_GEM_OBJECT_UNBIND_VM_TRYLOCK
We changed the locking hierarchy for both ppgtt and ggtt, so both locks
should be trylocked inside i915_gem_object_unbind().

we jump to the wrong address, for example like this:

drm/i915/gtt: map the PD up front
We need to generalise our accessor for the page directories and tables from
using the simple kmap_atomic to support local memory, and this setup
must be done on acquisition of the backing storage prior to entering
fence execution contexts. Here we replace the kmap with the object
mapping code that for simple single page shmemfs object will return a
plain kmap, that is then kept for the lifetime of the page directory.
Note that keeping the mapping around is a potential concern here, since
while the vma is pinned the mapping remains there for the PDs
underneath, or at least until the used_count reaches zero, at which
point we can safely destroy the mapping. For 32b this will be even worse
since the address space is more limited, but since this change mostly
impacts full ppGTT platforms, the justification is that for modern
platforms we shouldn't care too much about 32b.

via alloc_pd(vm) with one reference. If pin_pt_dma() failed, pde->pt.base
is freed by i915_gem_object_put() with a reference dropped. Then free_pd
calls free_px() defined in intel_ppgtt.c, which calls i915_gem_object_put()

As pde->pt.base is protected by refcount, so the second put will not free

add the correspondent macros for graphics and media. Going forward we
will prefer checking the versions for the specific IPs (graphics, media
and display) rather than grouping everything under a "gen" version.
For consistency and to make the maintenance easier, it'd be preferred
not to mix the *GEN* macros with the new ones. For older platforms we
can simply consider that the previous "gen" number will extend to all
3 IPs. Then we can start replacing its use in the driver. Right now this
replacement is not done and only the infrastructure is put in place.
We also leave gen and gen_mask inside struct intel_device_info while
it's still being used throughout the code.

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

- IS_DISPLAY_RANGE(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/gen12: Add recommended hardware tuning value
Follow Bspec 31870 to set recommended tuning values for certain GT
register. These values aren't workarounds per-se, but it's best to
handle them in the same general area of the driver, especially since
there may be real workarounds that update other bits of the same
registers.
At the moment the only value we need to worry about is the
TDS_TIMER setting in FF_MODE2. This setting was previously
described as "Wa_1604555607" on some platforms, but the spec
tells us that we should continue to program this on all current
gen12 platforms, even those that do not have that WA.

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.

Save some place in the GTT VMAs by using a u16 instead of unsigned int

4096 tiles in the worst case (yf-tiles), the maximum FB height is 16k

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_.
