We were only restoring fixed modes here. The DRM backend no longer
creates fixed modes when the compositor sets a custom mode, so we
need to handle this situation when restoring.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3698

wlr_client_buffer is a bad indicator for direct scan-out.
Compositors might use the underlying wlr_buffer instead.
|
|
This slightly improves type safety.
The culprits were found with:
git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'
|
|
This is a bit more type-safe.
|
|
This fixes an issue where the panel_orientation parameter was set but wlroots was ignoring it and
returning OUTPUT_TRANSFORM_NORMAL.
Fixes 2e12de96

|
|
|
Removes duplication across all the backends to finally apply the mode
to the output.
|
|
Nobody remembers why this is done and it isn't that great if people
use a lot of custom modes.
|
|
wlr_output_update_needs_frame() is called unconditionally at the
end of the function already.
|
|
This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.
A new wlr_output_state_init() function takes care of initializing
the Pixman region.

Destroying the liftoff_device invalidates all of the liftoff_planes.
Destroy the liftoff_planes before the liftoff_device to fix this.

The kernel complains when the damage exceeds the FB bounds:
[73850.448326] i915 0000:00:02.0: [drm:drm_atomic_check_only] [PLANE:31:plane 1A] invalid damage clip 0 0 2147483647 2147483647
Make the DRM backend behave like the Wayland one and allow compositors
to damage (0, 0, INT32_MAX, INT32_MAX) to repaint everything without
needing to know the exact buffer size.

Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory
The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.
|
|
This allows compositors to get back the raw drmModeModeInfo and
look at DRM-specific fields and flags.

Commit 90d08f8f1c40e2a302d62052435ff2abdb08a854 changed the way
wlr_drm_format_intersect worked, including passing in a destination
format list. This breaks scenarios where the intersection doesn't
find any matching formats, since we still have a valid destination
format set. This changes it to only return true if more than one
matching format is present in the intersection list.
|
|
|
|
Now it takes a reference to a destination format
|
|
|
|
|
|
Add a src_box state field. Use the SRC_* KMS props in the DRM
backend, reject the layers in the Wayland backend (for now, we can
support it later via viewporter).
|
|
This allows callers to set a destination size different from the
buffer size to scale them.
The DRM backend supports this. The Wayland backend doesn't yet
(we'd need to wire up viewporter).
|
|
Helps figuring out why e.g. get_primary_formats fails.
|
|
|
|
|
|
We've had this struct for a while. It'd be useful for compositors
if they want to manage the swap chains themselves instead of being
forced to use wlr_output's. Some compositors might also want to use
a swapchain without an output.
|
|
No need to store this info in struct wlr_drm_layer. We can just
extract the size when we need it.
|
|
The Pixman API now accepts const parameters.
|
|
|
|
|
|
This will be useful for implementing the output layers API.

The hardcoded fallback "/usr/share/hwdata/pnp.ids" was only a
temporary solution to get things working while distributions were
still working on shipping it.

Since 1d581656c756 ("backend/drm: set "max bpc" to the max") we
set the "max bpc" property to the maximum value. The kernel driver
is supposed to clamp this value depending on hardware capabilities.
All kernel drivers lower the value depending on the GPU capabilities.
However, none of the drivers lower the value depending on the DP-MST
link capabilities. Thus, enabling a 4k@60Hz mode can fail on some
DP-MST setups due to the "max bpc" property.
Additionally, it's not a good idea to unconditionally set "max bpc"
to the max. A high bpc consumes more lanes and more clock speed,
which means higher power consumption and the busy lanes cannot be
used for something else (e.g. other data transfers on a USB-C cable).
For now, let's tie the "max bpc" to the pixel format of the buffer.
Introduce a heuristic to make "high bit-depth buffer" a synonym of
"I want the best quality".
This is not perfect: a "max bpc" higher than 8 might be desirable
for pixel formats with a color depth of 8 bits, for instance when
the color management KMS properties are used. But we don't really
support that yet, so let's leave this for later.

When the user switches away from the VT where wlroots is running,
the new DRM master may mutate the KMS state in an arbitrary manner.
For instance, let's say wlroots uses the following connector/CRTC
mapping:
- CRTC 42 drives connector DP-1
- CRTC 43 drives connector DP-2
Then the new DRM master may swap the mapping like so:
- CRTC 42 drives connector DP-2
- CRTC 43 drives connector DP-1
wlroots needs to restore its own state when the user switches back.
Some state is attached to wlr_drm_crtc (e.g. current FB), so reading
back and adopting the CRTC/connector mapping left by the previous DRM
master would be complicated (this was the source of other bugs in the
past, see [1]).
With the previous logic, wlroots merely tries to restore the state
of each connector one after the other. This fails in the scenario
described above: the kernel refuses to use CRTC 42 for DP-1, because
that CRTC is already in-use for DP-2.
Unfortunately with the legacy uAPI it's not possible to restore the
state in one go. We need to support both legacy and atomic uAPIs, so
let's fix the bug for the legacy uAPI first, and then improve the
situation for the atomic uAPI as a second step [2].
We need to disable the CRTCs we're going to switch the connectors for.
This sounds complicated, so let's just disable all CRTCs to simplify.
This causes a black screen because of the on/off modesets, but makes
VT switch much more reliable, so I'll take it.

We already do it for get_drm_plane_props().
|
|
We only need it for one thing: gamma size. Moreover, some bits in
the drmModeCrtc will become out-of-date, for instance the current
mode, so let's avoid caching the whole struct and only keep what
we know won't change.
|
|
connect_drm_connector() may be called long after create_drm_connector().
During that time the DRM mode might have changed. Avoid working with
stale information.
|

|
|
If the kernel adds new enum entries for subpixel, don't read past
the end of the subpixel_map array.
|
|
match_obj() might return a configuration where the CRTC for an
enabled connector is switched to another one.
We don't support this correctly: the wlr_output common code would
need to query again the supported formats, re-allocate the
swapchain, etc.
What's more, the kernel doesn't even support this [1]: it
requires planes to be disabled to change their CRTC, it rejects
commits directly switching the CRTC used by a plane.

This list contains wlr_drm_connector entries, and there is no
guarantee that the wlr_output fields are initialized.
|
|
Ensure we unlock any pending cursor FB when disabling a connector.
|
|
If the commit fails, then our local state becomes out-of-sync with
the kernel's. Additionally, when disabling a connector without going
through dealloc_crtc(), conn->crtc would still be set.
Fix this by updating conn->crtc in drm_connector_commit_state().
