2020-05-14drm: plane: Verify that no or all planes have a zpos propertyLaurent Pinchart1-0/+9
The zpos property is used by userspace to sort the order of planes. While the property is not mandatory for drivers to implement, mixing planes with and without zpos confuses userspace, and shall not be allowed. Clarify this in the documentation and warn at runtime if the drivers mixes planes with and without zpos properties.

2019-04-24drm/lease: Make sure implicit planes are leasedDaniel Vetter1-0/+8
If userspace doesn't enable universal planes, then we automatically add the primary and cursor planes. But for universal userspace there's no such check (and maybe we only want to give the lessee one plane, maybe not even the primary one), hence we need to check for the implied plane. v2: don't forget setcrtc ioctl. v3: Still allow disabling of the crtc in SETCRTC.

2019-01-11drm: Auto-set allow_fb_modifiers when given modifiers at plane initPaul Kocialkowski1-0/+3
When drivers pass non-empty lists of modifiers for initializing their planes, we can infer that they allow framebuffer modifiers and set the driver's allow_fb_modifiers mode config element. In case the allow_fb_modifiers element was not set (some drivers tend to set them after registering planes), the modifiers will still be registered but won't be available to userspace unless the flag is set later. However in that case, the IN_FORMATS blob won't be created. In order to avoid this case and generally reduce the trouble associated with the flag, always set allow_fb_modifiers when a non-empty list of format modifiers is passed at plane init.

2018-11-29drm: Add DRM_MODESET_LOCK_BEGIN/END helpersSean Paul1-13/+3
This patch adds a couple of helpers to remove the boilerplate involved in grabbing all of the modeset locks. I've also converted the obvious cases in drm core to use the helpers. The only remaining instance of drm_modeset_lock_all_ctx() is in drm_framebuffer. It's complicated by the state clear that occurs on deadlock. ATM, there's no way to inject code in the deadlock path with the helpers, so it's unfit for conversion.

2018-09-14drm: Differentiate the lack of an interface from invalid parameterChris Wilson1-5/+5
If the ioctl is not supported on a particular piece of HW/driver combination, report ENOTSUP (aka EOPNOTSUPP) so that it can be easily distinguished from both the lack of the ioctl and from a regular invalid parameter. v2: Across all the kms ioctls we had a mixture of reporting EINVAL, ENODEV and a few ENOTSUPP (most where EINVAL) for a failed drm_core_check_feature(). Update everybody to report ENOTSUPP. v3: ENOTSUPP is an internal errno! It's value (524) does not correspond to a POSIX errno, the one we want is ENOTSUP. However, uapi/asm-generic/errno.h doesn't include ENOTSUP but man errno says "ENOTSUP and EOPNOTSUPP have the same value on Linux, but according to POSIX.1 these error values should be distinct." so use EOPNOTSUPP as its equivalent.

We use 32bit bitmasks to track planes/crtcs/encoders/connectors. Naturally we can only do that if the index of those objects stays below 32. Issue a warning whenever we exceed that limit, hopefully prompting someone to fix the problem. For connectors the issue is a bit more complicated as they can be created/destroyed at runtime due to MST. So the problem is no longer a purely theoretical programmer error.

2017-08-08drm: Handle properties in the core for atomic driversDaniel Vetter1-1/+1
The reason behind the original indirection through the helper functions was to allow existing drivers to overwrite how they handle properties. For example when a vendor-specific userspace had expectations that didn't match atomic. That seemed likely, since atomic is standardizing a _lot_ more of the behaviour of a kms driver. But 20 drivers later there's no such need at all. Worse, this forces all drivers to hook up the default behaviour, breaking userspace if they forget to do that. And it forces us to export a bunch of core function just for those helpers. And finally, these helpers are the last places using drm_atomic_legacy_backoff() and the implicit acquire_ctx. This patch here just implements the new behaviour and updates the docs. Follow-up patches will garbage-collect all the dead code. v2: Fixup docs even better! v3: Make it actually work ... v4: Drop the uses_atomic_modeset() checks from the previous patch again, since they're now moved up in the callchain.

2017-08-08drm: Don't update property values for atomic driversDaniel Vetter1-1/+1
Atomic drivers only use the property value store for immutable (i.e. can't be set by userspace, but the kernel can still adjust it) properties. The only tricky part is the removal of the update in drm_atomic_helper_update_legacy_modeset_state(). This was added in commit 8c10342cb48f3140d9abeadcfd2fa6625d447282 (tag: topic/drm-misc-2015-07-28) Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Mon Jul 27 13:24:29 2015 +0200 drm/atomic: Update legacy DPMS state during modesets, v3. by copying it from the i915 code, where it was originally added in commit 68d3472047a572936551f8ff0b6f4016c5a1fdef Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Sep 6 22:08:35 2012 +0200 drm/i915: update dpms property in set_mode for the legacy modeset code. The reason we needed this hack was that i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of the newer-ish drm_drv_uses_atomic_modeset(), which avoids such troubles. With the correct feature checks this isn't needed anymore at all. Also make sure that drivers don't accidentally get this wrong by making the exported version of drm_object_property_get_value() only work for legacy drivers.

2017-05-23drm: Fix deadlock retry loop in page_flip_ioctlDaniel Vetter1-2/+3
I failed to properly onion-wrap the unwind code: We acquire the vblank reference before we start with the wait-wound locking dance, hence we must make sure we retry before we drop the reference. Oops. v2: The vblank_put must be after the frambuffer_put (Michel). I suck at unwrapping code that doesn't use separate labels for each stage, but checks each pointer first ... While re-reading everything I also realized that we must clean up the fb refcounts, and specifically plane->old_fb before we drop the locks, either in the final unlocking, or in the w/w retry path. Hence the correct fix is to drop the vblank_put to the very bottom.
