2016-07-29drm: add generic zpos propertyMarek Szyprowski
version 8: - move drm_blend.o from drm-y to drm_kms_helper-y to avoid EXPORT_SYMBOL(drm_atomic_helper_normalize_zpos) - remove dead function declarations in drm_crtc.h version 7: - remove useless EXPORT_SYMBOL() - better z-order wording in Documentation version 6: - add zpos in gpu documentation file - merge Ville patch about zpos initial value and API improvement. I have split Ville patch between zpos core and drivers version 5: - remove zpos range check and comeback to 0 to N-1 normalization algorithm version 4: - make sure that normalized zpos value is stay in the defined property range and warn user if not This patch adds support for generic plane's zpos property property with well-defined semantics: - added zpos properties to plane and plane state structures - added helpers for normalizing zpos properties of given set of planes - well defined semantics: planes are sorted by zpos values and then plane id value if zpos equals Normalized zpos values are calculated automatically when generic muttable zpos property has been initialized. Drivers can simply use plane_state->normalized_zpos in their atomic_check and/or plane_update callbacks without any additional calls to DRM core. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Compare to Marek's original patch zpos property is now specific to each plane and no more to the core. Normalize function take care of the range of per plane defined range before set normalized_zpos.

2016-07-19drm: drm_connector->s/connector_id/index/ for consistencyDaniel Vetter
connector_id in the uapi actually means drm_connector->base.id, which is something entirely different. And ->index is also consistent with plane/encoder/CRTCS and the various drm_*_index() functions. While at it also improve/align the kerneldoc comment. v2: Mention where those ids are from ... v3: Add -ing to supporting and try to not break the world.

If a driver wants to more precisely control its initialisation and in particular, defer registering its interfaces with userspace until after everything is setup, it also needs to defer registering the connectors.

2016-06-10drm/atomic-helper: nonblocking commit supportDaniel Vetter
Design ideas: - split up the actual commit into different phases, and have completions for each of them. This will be useful for the future when we want to interleave phases much more aggressively, for e.g. queue depth > 1. For not it's just a minimal optimization compared to current common nonblocking implementation patterns from drivers, which all stall for the entire commit to complete, including vblank waits and cleanups. - Extract a separate atomic_commit_hw hook since that's the part most drivers will need to overwrite, hopefully allowing even more shared code. - Enforce EBUSY seamntics by attaching one of the completions to the flip_done vblank event. Side benefit of forcing atomic drivers using these helpers to implement event handlign at least semi-correct. I'm evil that way ;-) - Ridiculously modular, as usual. - The main tracking unit for a commit stays struct drm_atomic_state, and the ownership rules for that are unchanged. Ownership still gets transferred to the driver (and subsequently to the worker) on successful commits. What is added is a small, per-crtc, refcounted structure to track pending commits called struct drm_crtc_commit. No actual state is attached to that though, it's purely for ordering and waiting. - Dependencies are implicitly handled by assuming that any CRTC part of &drm_atomic_state is a dependency, and that the current commit must wait for any commits to complete on those CRTC. This way drivers can easily add more depencies using drm_atomic_get_crtc_state(), which is very natural since in most case a dependency exists iff there's some bit of state that needs to be cross checked. Removing depencies is not possible, drivers simply need to be careful to not include every CRTC in a commit if that's not necessary. Which is a good idea anyway, since that also avoids ww_mutex lock contention. - Queue depth > 1 sees some prep work in this patch by adding a stall paramater to drm_atomic_helper_swap_states(). To be able to push commits entirely free-standing and in a deeper queue through the back-end the driver must not access any obj->state pointers. This means we need to track the old state in drm_atomic_state (much easier with the consolidated arrays), and pass them all explicitly to driver backends (this will be serious amounts of churn). Once that's done stall can be set to false in swap_states. v2: Dont ask for flip_done signalling when the CRTC is off and stays off: Drivers don't handle events in that case. Instead complete right away. This way future commits don't need to have special-case logic, but can keep blocking for the flip_done completion. v3: Tons of fixes: - Stall for preceeding commit for real, not the current one by accident. - Add WARN_ON in case drivers don't fire the drm event. - Don't double-free drm events. v4: Make legacy cursor not stall. v5: Extend the helper hook to cover the entire commit tail. Some drivers need special code for cleanup and vblank waiting, this makes it a bit more useful. Inspired by the rockchip driver. v6: Add WARN_ON to catch drivers who forget to send out the drm event. v7: Fixup the stalls in swap_state for real!! v8: - Fixup trailing whitespace, spotted by Maarten. - Actually wait for flip_done in cleanup_done, like the comment says we should do. Thanks a lot for Tomeu for helping with debugging this on. v9: Now with awesome kerneldoc! v10: Split out drm_crtc_commit tracking infrastructure. v: - Add missing static (Gustavo). - Split out the sync functions, only do the actual nonblocking logic in this patch (Maarten).

2016-06-03drm: Store the plane's indexChris Wilson
Currently the plane's index is determined by walking the list of all planes in the mode and finding the position of that plane in the list. A linear walk, especially a linear walk within a linear walk as frequently conceived by i915.ko [O(N^2)] quickly comes to dominate profiles. The plane's index is constant for as long as no earlier planes are removed from the list. For all drivers, planes are static, determined at boot and then untouched until shutdown. In fact, there is no locking provided to allow for dynamic removal of planes/encoders/crtcs. v2: Convert drm_crtc_index() and drm_encoder_index() as well. v3: Stop adjusting the indices upon removal; consider the list construct-only.

Needs to be regened with newer drivers, but probably only after -rc1 to catch them all. - actually lockless gem_object_free, plus acked driver conversion patches. All the trickier prep stuff already is in drm-next. - Noralf's nice work for generic defio support in our fbdev emulation.

2016-05-02drm/atomic: Rename async parameter to nonblocking.Maarten Lankhorst
This is the first step of renaming async commit to nonblocking commit. The flag passed by userspace is NONBLOCKING, and async has a different meaning for page flips, where it means as soon as possible.

2016-04-27drm: Switch blobs to the new generic modeset obj refcountingDaniel Vetter
Need to move the free function around a bit, but otherwise mostly just removing code. Specifically we can nuke all the _locked variants since the weak idr reference is now protected by the idr_mutex, which we never hold anywhere expect in the lookup/reg/unreg functions. And those never call anything else. Another benefit of this is that this patch switches the weak reference logic from kref_put_mutex to kref_get_unless_zero. And the later is in general more flexible wrt accomodating multiple weak references protected by different locks, which might or might not come handy eventually. But one consequence of that switch is that we need to acquire the blob_lock from the free function for the list_del calls. That's a bit tricky to pull off, but works well if we pick the exact same scheme as is already used for framebuffers. Most important changes: - filp list is maintainer by create/destroy_blob ioctls directly (already the case, so we can just remove the redundant list_del from the free function). - filp close handler walks the filp-private list lockless - works because we know no one else can access it. I copied the same comment from the fb code over to explain this. - Otherwise we need to sufficiently restrict blob_lock critical sections to avoid all the unreference calls. Easy to do once the blob_lock only protects the list, and no longer the weak reference.

2016-03-08drm: introduce pipe color correction propertiesLionel Landwerlin
Patch based on a previous series by Shashank Sharma. This introduces optional properties to enable color correction at the pipe level. It relies on 3 transformations applied to every pixels displayed. First a lookup into a degamma table, then a multiplication of the rgb components by a 3x3 matrix and finally another lookup into a gamma table. The following properties can be added to a pipe : - DEGAMMA_LUT : blob containing degamma LUT - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT - CTM : transformation matrix applied after the degamma LUT - GAMMA_LUT : blob containing gamma LUT - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by the driver to tell userspace applications what sizes should be the lookup tables in DEGAMMA_LUT and GAMMA_LUT. A helper is also provided so legacy gamma correction is redirected through these new properties. v2: Register LUT size properties as range v3: Fix round in drm_color_lut_get_value() helper More docs on how degamma/gamma properties are used v4: Update contributors v5: Rename CTM_MATRIX property to CTM (Doh!)

2016-03-08drm/atomic: Handle encoder stealing from set_config better.Maarten Lankhorst
Instead of failing with -EINVAL when conflicting encoders are found, the legacy set_config will disable other connectors when encoders conflict. With the previous commit this becomes a lot easier to implement. set_config only adds connectors to the state that are modified, and because of the previous commit that calls add_affected_connectors only on set->crtc it means any connector not part of the modeset can be stolen from. We disable the connector in that case, and possibly the crtc if required. Atomic modeset itself still doesn't allow encoder stealing, the results would be too unpredictable.

2016-02-19drm/atomic: Allow for holes in connector state, v2.Maarten Lankhorst
Because we record connector_mask using 1 << drm_connector_index now the connector_mask should stay the same even when other connectors are removed. This was not the case with MST, in that case when removing a connector all other connectors may change their index. This is fixed by waiting until the first get_connector_state to allocate connector_state, and force reallocation when state is too small. As a side effect connector arrays no longer have to be preallocated, and can be allocated on first use which means a less allocations in the page flip only path. Changes since v1: - Whitespace.
