* | drm/gma500: Add driver private mutex for the fault handlerDaniel Vetter2015-12-013-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's currently two places where the gma500 fault handler relies upon dev->struct_mutex: - To protect r->mappping - To make sure vm_insert_pfn isn't called concurrently (in which case the 2nd thread would get an error code). Everything else (specifically psb_gtt_pin) is already protected by some other locks. Hence just create a new driver-private mmap_mutex just for this function. With this gma500 is complete dev->struct_mutex free!

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

|/ | | | | | | | | | | | | | One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

| * drm: Introduce drm_fb_helper_prepare()Thierry Reding2014-07-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

Given that the default mapping_gfp_mask() is GFP_HIGHUSER, it is _very_ unlikely that anyone will ever make use of that parameter. In fact, all drivers currently pass redundant flags or 0. This patch removes the 'gfp' parameter. The only reason to keep it is to remove flags like __GFP_WAIT. But in its current form, it can only be used to add flags. So to remove __GFP_WAIT, you'd have to drop it from the mapping_gfp_mask, which again is stupid as this mask is used by shmem-core for other allocations, too. If any driver ever requires that parameter, we can introduce a new helper that takes the raw 'gfp' parameter. The caller'd be responsible to combine it with mapping_gfp_mask() in a suitable way. The current drm_gem_get_pages() helper would then simply use mapping_gfp_mask() and call the new helper. This is what shmem_read_mapping_pages{_gfp,} does right now. Moreover, the gfp-zone flag-usage is not obvious: If you pass a modified zone, shmem core will WARN() or even BUG(). In other words, the following must be true for 'gfp' passed to shmem_read_mapping_pages_gfp(): gfp_zone(mapping_gfp_mask(mapping)) == gfp_zone(gfp) Add a comment to drm_gem_read_pages() explaining that constraint.

Now since this is init code locking is fairly redudant if it wouldn't be for the drm core registering sysfs files a bit early. And the locking WARNINGs nicely enforce that indeed all access to the mode lists are properly protected. And a full audit shows that only i915 and gma500 touch the modes lists at init time.
