2014-11-27drm/atomic: clear plane's CRTC and FB when shutting downRob Clark1-6/+13
Otherwise we'd still end up w/ the plane attached to the CRTC, and seemingly active, but without an FB. Which ends up going *boom* in the drivers. Slightly modified version of Daniel's irc suggestion. Note that the big problem isn't drivers going *boom* here (since we already have the situation of planes being left enabled when the crtc goes down). The real issue is that the core assumes the primary plane always goes down when calling ->set_config with a NULL mode. Ignoring that assumption leads to the legacy state pointers plane->fb/crtc getting out of sync with atomic, and that then leads to the subsequent *boom* all over the place.

2014-11-27drm: Handle atomic state properly in kms getfoo ioctlDaniel Vetter1-3/+46
So the problem with async commit (especially async modeset commit) is that the legacy pointers only get updated after the point of no return, in the async part of the modeset sequence. At least as implemented by the current helper functions. This is done in the set_routing_links function in drm_atomic_helper.c. Which also means that access isn't protected by locks but only coordinated by synchronizing with async workers. No problem thus far, until we lock at the getconnector/encoder ioctls. So fix this up by adding special cases for atomic drivers: For those we need to look at state objects. Unfortunately digging out the correct encoder->crtc link is a bit of work, so wrap this up in a helper function. Moving the assignments of connector->encoder and encoder->crtc earlier isn't a good idea because the point of the atomic helpers is that we stage the state updates. That way the disable functions can still inspect the links and rely upon them. v2: Extract full encoder->crtc lookup into helper (Rob). v3: Extract drm_connector_get_encoder too since - we need to always return state->best_encoder when there is a state otherwise we might return stale data if there's a pending async disable (and chase unlocked pointers, too). Same issue with encoder_get_crtc but there it's a bit more tricky to handle.

2014-11-27drm/atomic: track bitmask of planes attached to crtcRob Clark4-14/+38
Chasing plane->state->crtc of planes that are *not* part of the same atomic update is racy, making it incredibly awkward (or impossible) to do something simple like iterate over all planes and figure out which ones are attached to a crtc. Solve this by adding a bitmask of currently attached planes in the crtc-state. Note that the transitional helpers do not maintain the plane_mask. But they only support the legacy ioctls, which have sufficient brute-force locking around plane updates that they can continue to loop over all planes to see what is attached to a crtc the old way. Signed-off-by: Rob Clark <robdclark@gmail.com> [danvet: - Drop comments about locking in set_crtc_for_plane since they're a bit misleading - we already should hold lock for the current crtc. - Also WARN_ON if get_state on the old crtc fails since that should have been done already. - Squash in fixup to check get_plane_state return value, reported by Dan Carpenter and acked by Rob Clark.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2014-11-25drm/atomic_helper: Cope with plane->crtc == NULL in disable helperJasper St. Pierre1-0/+11
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.

2014-11-25drm/atomic-helper: Skip vblank waits for unchanged fbsDaniel Vetter1-1/+33
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.

2014-11-21drm/msm/mdp5: make SMP module dynamically configurableStephane Viau5-153/+265
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: Stephane Viau <sviau@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2014-11-21drm/msm/mdp5: use irqdomainsRob Clark6-26/+122
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: Rob Clark <robdclark@gmail.com>
