2014-12-09drm: add tile_group support. (v3)Dave Airlie1-0/+4
A tile group is an identifier shared by a single monitor, DisplayID topology has 8 bytes we can use for this, just use those for now until something else comes up in the future. We assign these to an idr and use the idr to tell userspace what connectors are in the same tile group. DisplayID v1.3 says the serial number must be unique for displays from the same manufacturer. v2: destroy idr (dvdhrm) add docbook (danvet) airlied:- not sure how to make docbook add fns to tile group section. v3: fix missing unlock.

drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input Some drivers erroneously treat the .pitch and .size fields of struct drm_mode_create_dumb as inputs. While the include/uapi/drm/drm_mode.h header has a comment denoting them as outputs, that seemingly wasn't enough to make drivers use them properly. The result is that some userspace doesn't explicitly zero out those fields, assuming that the kernel won't use them. That causes problems since the data within the structure might be uninitialized, so bogus data may end up confusing drivers (ridiculously large values for the pitch, ...). This series attempts to improve the situation by fixing all drivers to not use the output fields. Furthermore to spare new drivers this bad surprise, the DRM core now zeros out these fields prior to handing the data structure to the driver. Lessons learned from this are that future IOCTLs should be properly documented (in the DRM DocBook for example) and should be rigorously defined. To prevent misuse like this, userspace should be required to zero out all output fields. The kernel should check for this and fail if that's not the case. * tag 'drm/gem-cma/for-3.19-rc1' of git://people.freedesktop.org/~tagr/linux: drm/cma: Remove call to drm_gem_free_mmap_offset() drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input drm/rcar: gem: dumb: pitch is an output drm/omap: gem: dumb: pitch is an output drm/cma: Introduce drm_gem_cma_dumb_create_internal() drm/doc: Add GEM/CMA helpers to kerneldoc drm/doc: mm: Fix indentation drm/gem: Fix a few kerneldoc typos

So here's my atomic series, finally all debugged&reviewed. Sean Paul has done a full detailed pass over it all, and a lot of other people have commented and provided feedback on some parts. Rob Clark also converted msm over the w/e and seems happy. The only small thing is that Rob wants to export the wait_for_vblank, which imo makes sense. Since there's other stuff still to do I think we should apply Rob's patch (once it has grown appropriate kerneldoc) later on top of this. This is just the core<->driver interface plus a big pile of helpers. Short recap of the main ideas: - There are essentially three helper libraries in this patch set: * Transitional helpers to use the new plane callbacks for legacy plane updates and in the crtc helper's ->mode_set callback. These helpers are only temporarily used to convert drivers to atomic, but they allow a nice separation between changing the driver backend and switching to the atomic commit logic. * Legacy helpers to implement all the legacy driver entry points (page_flip, set_config, plane vfuncs) on top of the new atomic driver interface. These are completely driver agnostic. The reason for having the legacy support as helpers is that drivers can switch step-by-step. And they could e.g. even keep the legacy page_flip code around for some old platforms where converting to full-blown atomic isn't worth it. * Atomic helpers which implement the various new ->atomic_* driver interfaces in terms of the revised crtc helper and new plane helper hooks. - The revised crtc helper implemenation essentially implements all the lessons learned in the i915 modeset rework (when using the atomic helpers only): * Enable/disable sequence for a given config are always the same and callbacks are always called in the same order. This contrast starkly with the crtc helpers, where the sequence of operations is heavily dependent on the previous config. One corollary of this is that if the configuration of a crtc only partially changes (e.g. a connector moves in a cloned config) the helper code will still disable/enable the full display pipeline. This is the only way to ensure that the enable/disable sequence is always the same. * It won't call disable or enable hooks more than once any more because it lost track of state, thanks to the atomic state tracking. And if drivers implement the ->reset hook properly (by either resetting the hw or reading out the hw state into the atomic structures) this even extends to the hardware state. So no more disable-me-harder kind of nonsense. * The only thing missing is the hw state readout/cross-check support, but if drivers have hw state readout support in their ->reset handlers it's simple to extend that to cross-check the hw state. * The crtc->mode_set callback is gone and its replacement only sets crtc timings and no longer updates the primary plane state. This way we can finally implement primary planes properly. - The new plane helpers should be suitable enough for pretty much everything, and a perfect fit for hardware with GO bits. Even if they don't fit the atomic helper library is rather flexible and exports all the functions for the individual steps to drivers. So drivers can pick what matches and implement their own magic for everything else. - A big difference compared to all previous atomic series is that this one doesn't implement async commit in a generic way. Imo driver requirements for that are too diverse to create anything reasonable sane which would actually work on a reasonable amount of different drivers. Also, we've never had a helper library for page_flips even, so it's really hard to know what might work and what's stupid without a bit of experience in the form of a few driver implementations. I think with the current flexibility for drivers to pick individual stages and existing helpers like drm_flip_queue it's rather easy though to implement proper async commit. - There's a few other differences of minor importance to earlier atomic series: * Common/generic properties are parsed in the callers/core and not in drivers, and passed to drivers by directly setting the right members in atomic state structures. That greatly simplifies all the transitional and legacy helpers an removes a lot of boilerplate code. * There's no crazy trylock mode used for the async commit since these helpers don't do async commit. A simple ordered flip queue of atomic state updates should be sufficient for preventing concurrent hw access anyway, as long as synchronous updates stall correctly with e.g. flush_work_queue or similar function. Abusing locks to enforce ordering isn't a good idea imo anyway. * These helpers reuse the existing ->mode_fixup hooks in the atomic_check callback. Which means that drivers need to adapat and move a lot less code into their atomic_check callbacks. Now this isn't everything needed in the drm core and helpers for full atomic support. But it's enough to start with converting drivers, and except for actually testing multiplane and multicrtc updates also enough to implement full atomic updates. Still missing are: - Per-plane locking. Since these helpers here encapsulate the locking completely this should be fairly easy to implement. - fbdev support for atomic_check/commit, so that multi-pipe finally works sanely in fbcon. - Adding and decoding shared/core properties. That just needs to be rebased from Rob's latest patch series, with minor adjustments so that the decoding happens in the core instead of in drivers. - Actually adding the atomic ioctl. Again just rebasing Rob's latest patch should be all that's needed. - Resolving how to deal with DPMS in atomic. Atomic is a good excuse to fix up the crazy semantics dpms currently has. I'm floating an RFC about this topic already. - Finally I couldn't test connector/encoder stealing properly since my test vehicle here doesn't allow a connector on different crtcs. So drivers which support this might see some surprises in that area. There is no semantic change though in how encoder stealing and assignment works (or at least no intended one), so I think the risk is minimal. As just mentioned I've done a fake conversion of an existing driver using crtc helpers to debug the helper code and validate the smooth transition approach. And that smooth transition was the really big motivation for this. It seems to actually work and consists of 3 phases: Phase 1: Rework driver backend for crtc/plane helpers The requirement here is that universal plane support is already implement. If universal plane support isn't implement yet it might be better though to just do it as part of this phase, directly using the new plane helpers. There are two big things to do: - Split up the existing ->update/disable_plane hooks into check/commit hooks and extract the crtc-wide prep/flush parts (like setting/clearing GO bits). - The other big change is to split the crtc->mode_set hook into the plane update (done using the plane helpers) and the crtc setup in a new ->mode_set_nofb hook. When phase 1 is complete the driver implements all the new callbacks which push the software state into hardware, but still using all the legacy entry points and crtc helpers. The transitional helpers serve as impendance mismatch here. Phase 2: Rework state handling This consists of rolling out the state handling helpers for planes, crtcs and connectors and reviewing all ->mode_fixup and similar hooks to make sure they don't depend upon implicit global state which might change in the atomic world. Any such code must be moved into ->atomic_check functions which just rely on the free-standing atomic state update structures. This phase also adds a few small pieces of fixup code to make sure the atomic state doesn't get out of sync in the legacy driver callbacks. Phase 3: Roll out atomic support Now it's just about replacing vfuncs with the ones provided by the helper and filling out the small missing pieces (like atomic_check logic or async commit support needed for page_flips). Due to the prep work in phase 1 no changes to the driver backend functions should be required, and because of the prep work in phase 2 atomic implementations can be rolled out step-by-step. So if async commit ins't implemented yet page_flip can be implemented with the legacy functions without wreaking havoc in the other operations. * tag 'topic/atomic-helpers-2014-11-09' of git://anongit.freedesktop.org/drm-intel: drm/atomic: Refcounting for plane_state->fb drm: Docbook integration and over sections for all the new helpers drm/atomic-helpers: functions for state duplicate/destroy/reset drm/atomic-helper: implement ->page_flip drm/atomic-helpers: document how to implement async commit drm/atomic: Integrate fence support drm/atomic-helper: implementatations for legacy interfaces drm: Atomic crtc/connector updates using crtc/plane helper interfaces drm/crtc-helper: Transitional functions using atomic plane helpers drm/plane-helper: transitional atomic plane helpers drm: Add atomic/plane helpers drm: Global atomic state handling drm: Add atomic driver interface definitions for objects drm/modeset_lock: document trylock_only in kerneldoc drm: fixup kerneldoc in drm_crtc.h drm: Pull drm_crtc.h into the kerneldoc template drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.h

2014-11-05drm: Global atomic state handlingDaniel Vetter1-0/+4
Some differences compared to Rob's patches again: - Dropped the committed and checked booleans. Checking will be internally enforced by always calling ->atomic_check before ->atomic_commit. And async handling needs to be solved differently because the current scheme completely side-steps ww mutex deadlock avoidance (and so either reinvents a new deadlock avoidance wheel or like the current code just deadlocks). - State for connectors needed to be added, since now they have a full-blown drm_connector_state (so that drivers have something to attach their own stuff to). - Refcounting is gone. I plane to solve async updates differently, since the lock-passing scheme doesn't cut it (since it abuses ww mutexes). Essentially what we need for async is a simple ownership transfer from the caller to the driver. That doesn't need full-blown refcounting. - The acquire ctx is a pointer. Real atomic callers should have that on their stack, legacy entry points need to put the right one (obtained by drm_modeset_legacy_acuire_ctx) in there. - I've dropped all hooks except check/commit. All the begin/end handling is done by core functions and is the same. - commit/check are just thin wrappers that ensure that ->check is always called. - To help out with locking in the legacy implementations I've added a helper to just grab all locks in the backoff case. v2: Add notices that check/commit can fail with EDEADLK. v3: - More consistent naming for state_alloc. - Add state_clear which is needed for backoff and retry. v4: Planes/connectors can switch between crtcs, and we need to be careful that we grab the state (and locks) for both the old and new crtc. Improve the interface functions to ensure this. v5: Add functions to grab affected connectors for a crtc and to recompute the crtc->enable state. This is useful for both helper and atomic ioctl code when e.g. removing a connector. v6: Squash in fixup from Fengguang to use ERR_CAST. v7: Add debug output. v8: Make checkpatch happy about kcalloc argument ordering. v9: Improve kerneldoc in drm_crtc.h v10: - Fix another kcalloc argument misorder I've missed. - More polish for kerneldoc. v11: Clarify the ownership rules for the state object. The new rule is that a successful drm_atomic_commit (whether synchronous or asnyc) always inherits the state and is responsible for the clean-up. That way async and sync ->commit functions are more similar. v12: A few bugfixes: - Assign state->state pointers correctly when grabbing state objects - we need to link them up with the global state. - Handle a NULL crtc in set_crtc_for_plane to simplify code flow a bit for the callers of this function. v13: Review from Sean: - kerneldoc spelling fixes - Don't overallocate states->planes. - Handle NULL crtc in set_crtc_for_connector. v14: Sprinkle __must_check over all functions which do wait/wound locking to make sure callers don't forget this.
