The plane helpers aren't pulled into the DocBook yet, so these weren't noticed. Reviewed-by:

In most situations it will be useful to have the old state passed to the ->atomic_update() callback. For example if a plane is being disabled the new state's .crtc field will be NULL, but some drivers may rely on this field to program the CRTCs registers. v2: rename variable to old_plane_state and remove redundant comment as suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to drm-next and add a hunk for pending MSM mdp5 changes Reviewed-by:

The drm core can call the plane disable hook multiple times, which means it can get called when plane->crtc is already NULL. That in turn means we can't get at the implicit acquire ctx we use in the atomic helpers for legacy entries points. We could try to pass drm_modeset_legacy_acquire_ctx a drm_device pointer so that it can cope with a NULL crtc. But that still doesn't work since the cursor ioctls (remapped with the universal cursor plane support code) only grabs the crtc locks. So the global acquire context isn't set eitehr. The real solution here would be to bite the bullet and wire up explicit acquire context parameters to all relevant functions. We need to do that anyway (to be able to get rid of some small allocations which we can't cope with failing). But that's a lot of work and better done once atomic has settled a bit. So meanwhile just catch this case in the helper and bail out. Signed-off-by:

Especially with legacy cursor ioctls existing userspace assumes that you can pile up lots of updates in one go. The super-proper way to support this would be a special commit mode which overwrites the last update. But getting there will be quite a bit of work. Meanwhile do what pretty much all the drivers have done for the plane update functions: Simply skip the vblank wait for the buffer cleanup if the buffer is the same. Since the universal cursor plane code will not recreate framebuffers needlessly this allows us to not slow down legacy pageflip events while someone moves the cursor around. v2: Drop the async plane update hunk from a previous attempt at this issue. v3: Fix up kerneldoc. v4: Don't oops so badly.

Now that we have the bits needed for mdp5 atomic, here is the followup pull request I mentioned. Main highlights are: 1) mdp5 multiple crtc and public plane support (no more hard-coded mixer setup!) 2) mdp5 atomic conversion 3) couple atomic helper fixes for issues found during mdp5 atomic debug (reviewed by danvet.. but he didn't plane to send an atomic-fixes pull request so I agreed to tack them on to mine) * 'msm-next' of git://people.freedesktop.org/~robclark/linux: drm/atomic: shutdown *current* encoder drm/atomic: check mode_changed *after* atomic_check drm/msm/mdp4: fix mixer setup for multi-crtc + planes drm/msm/mdp5: dpms(OFF) cleanups drm/msm/mdp5: atomic drm/msm: atomic fixes drm/msm/mdp5: remove global mdp5_ctl_mgr drm/msm/mdp5: don't use void * for opaque types drm/msm: add multiple CRTC and overlay support drm/msm/mdp5: set rate before enabling clk drm/msm/mdp5: introduce mdp5_cfg module drm/msm/mdp5: make SMP module dynamically configurable drm/msm/hdmi: remove useless kref drm/msm/mdp5: get the core clock rate from MDP5 config drm/msm/mdp5: use irqdomains

In disable_outputs() we need to shut down the outgoing encoder, not the incoming one (we have already swapped-state at this point). Without this, we end up telling the driver to crtc->dpms(OFF) without first encoder->dpms(OFF), and that makes some hw quite unhappy. v2: missing WARN_ON() hunk and comment Reviewed-by:

The intention is that drivers can set crtc_state->mode_changed in their atomic_check() fxns if they encounter a scenario that requires full modeset. Signed-off-by:

On mdp4 there is a single global LAYERMIXER_IN_CFG register. The previous logic to share that between multiple crtcs didn't actually handle plane-disable very well. Easier just to look at all of the crtcs each time. Signed-off-by: -

When disabling the interface (INTF), the change doesn't latch until next vblank, so we need to wait for vblank. Also, to be pedantic, in the crtc, set all the mixer stages to unused. It shouldn't really matter, since at this point we have already disabled the INTF and waited for necessary vblank. Signed-off-by: -

Convert mdp5 over to atomic helpers. Extend/wrap drm_plane_state to track plane zpos and to keep track of the needed when applying the atomic update. In mdp5's plane->atomic_check() we also need to check for updates which require SMP reallocation, in order to trigger full modeset. Signed-off-by: -

For example, use 'struct mdp5_smp *' everywhere instead of 'void *', but only declare it as 'struct mdp5_smp;' in common headers, so the struct body is still private. The accomplishes the desired modularity while still letting the compiler provide some type checking for us. Signed-off-by: -

The Shared Memory Pool (SMP) has its own limitation, features and state. Some examples are: - the number of Memory Macro Block (MMB) and their size - the number of lines that can be fetched - the state of MMB currently allocated - the computation of number of blocks required per plane - client IDs ... In order to avoid private data to be overwritten by other modules, let's make these private to the SMP module. Some of these depend on the hardware configuration, let's add them to the mdp5_config struct. In some hw configurations, some MMBs are statically tied to RGB pipes and cannot be re-allocated dynamically. This change introduces the concept of MMB static usage and makes sure that dynamic MMB requests are dimensioned accordingly. A note on passing a pipe pointer, instead of client IDs: Client IDs are SMP-related information. Passing PIPE information to SMP lets SMP module to find out which SMP client(s) are used. This allows the SMP module to access the PIPE pointer, which can be used for FIFO watermark configuration. By the way, even though REG_MDP5_PIPE_REQPRIO_FIFO_WM_* registers are part of the PIPE registers, their functionality is to reflect the behavior of the SMP block. These registers access is now restricted to the SMP module. Signed-off-by:

A left-over from prior to component framework. The original intent was to deal with hdmi getting unloaded before the master component, but that isn't really going to work anyways. These days with the component framework taking care to unload the master component first, we don't have to worry about this. Signed-off-by: -

The core clock rate depends on the hw configuration. Once we have read the hardware revision, we can set the core clock to its maximum value. Before then, the clock is set at a rate supported by all MDP5 revisions. Signed-off-by:

For mdp5, the irqs of hdmi/eDP/dsi0/dsi1 blocks get routed through the mdp block. In order to decouple hdmi/eDP/etc, register an irq domain in mdp5. When hdmi/dsi/etc are used with mdp4, they can directly setup their irqs in their DT nodes as normal. When used with mdp5, instead set the mdp device as the interrupt-parent, as in: mdp: qcom,mdss_mdp@fd900000 { compatible = "qcom,mdss_mdp"; interrupt-controller; #interrupt-cells = <1>; ... }; hdmi: qcom,hdmi_tx@fd922100 { compatible = "qcom,hdmi-tx-8074"; interrupt-parent = <&mdp>; interrupts = <8 0>; /* MDP5_HW_INTR_STATUS.INTR_HDMI */ ... }; There is a slight awkwardness, in that we cannot disable child irqs at the mdp level, they can only be cleared in the child block. So you must not use threaded irq handlers in the child. I'm not sure if there is a better way to deal with that. Signed-off-by: -

It happens on occasion that developers of generic user-space applications abuse the dumb buffer API to get hold of drm buffers that they can both mmap() and use for GPU acceleration, using the assumptions that dumb buffers and buffers available for GPU are a) The same type and can be aribtrarily type-casted. b) fully coherent. This patch makes the most widely used drivers warn nicely when that happens, the next step will be to fail. v2: Move drmP.h changes to drm_gem.h. Fix Radeon dumb mmap breakage. Signed-off-by:
