| | * drm/msm/rd: support for 64b iovaRob Clark2016-11-281-2/+2
| | | | | | | | | | | | | | | | | | | | | For backwards compat, the rd format puts the high 32b after the size field in the GPUADDR packet. Signed-off-by: Rob Clark <robdclark@gmail.com>
| | * drm/msm: convert iova to 64bRob Clark2016-11-2815-32/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | For a5xx the gpu is 64b so we need to change iova to 64b everywhere. On the display side, iova is still 32b so it can ignore the upper bits. (Although all the armv8 devices have an iommu that can map 64b pa to 32b iova.) Signed-off-by: Rob Clark <robdclark@gmail.com>

| | * drm/msm: Remove bad calls to of_node_put()Archit Taneja2016-11-271-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In add_components_mdp, we parse the endpoints in MDP output ports using the helper for_each_endpoint_of_node(). Our function calls of_node_put() on the endpoint node before we iterate over the next one. This is already done by the helper, and results in trying to decrement the refcount twice. Remove the extra of_node_put calls. This fixes warnings seen when we try to insert the driver as a module on IFC6410.

| | * drm/msm/mdp5: move LM bounds check into plane->atomic_check()Rob Clark2016-11-272-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mode_config->max_{width,height} is for the maximum size of a fb, not the max scanout limits (of the layer-mixer). It is legal, and in fact common, to create a larger fb, only only scan-out a smaller part of it. For example multi-monitor configurations for x11, or android wallpaper layer (which is created larger than the screen resolution for fast scrolling by just changing the src x/y coordinates).

| | * drm/msm/mdp5: handle SMP block allocations "atomically"Rob Clark2016-11-277-245/+193
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, SMP block allocation was not checked in the plane's atomic_check() fxn, so we could fail allocation SMP block allocation at atomic_update() time. Re-work the block allocation to request blocks during atomic_check(), but not update the hw until committing the atomic update. Since SMP blocks allocated at atomic_check() time, we need to manage the SMP state as part of mdp5_state (global atomic state). This actually ends up significantly simplifying the SMP management, as the SMP module does not need to manage the intermediate state between assigning new blocks before setting flush bits and releasing old blocks after vblank. (The SMP registers and SMP allocation is not double-buffered, so newly allocated blocks need to be updated in kms->prepare_commit() released blocks in kms->complete_commit().)

| | * drm/msm/mdp5: dynamically assign hw pipes to planesRob Clark2016-11-276-80/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (re)assign the hw pipes to planes based on required caps, and to handle situations where we could not modify an in-use plane (ie. SMP block reallocation). This means all planes advertise the superset of formats and properties. Userspace must (as always) use atomic TEST_ONLY step for atomic updates, as not all planes may be available for use on every frame. The mapping of hwpipe to plane is stored in mdp5_state, so that state updates are atomically committed in the same way that plane/etc state updates are managed. This is needed because the mdp5_plane_state keeps a pointer to the hwpipe, and we don't want global state to become out of sync with the plane state if an atomic update fails, we hit deadlock/ backoff scenario, etc. The use of state_lock keeps multiple parallel updates which both re-assign hwpipes properly serialized.

| | * drm/msm/mdp5: add skeletal mdp5_stateRob Clark2016-11-272-0/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add basic state duplication/apply mechanism. Following commits will move actual global hw state into this. The state_lock allows multiple concurrent updates to proceed as long as they don't both try to alter global state. The ww_mutex mechanism will trigger backoff in case of deadlock between multiple threads trying to update state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split out the hardware pipe specifics from mdp5_plane. To start, the hw pipes are statically assigned to planes, but next step is to assign the hw pipes during plane->atomic_check() based on requested caps (scaling, YUV, etc). And then hw pipe re-assignment if required if required SMP blocks changes. Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Archit Taneja <architt@codeaurora.org>

Also fix the case where there are zero enabled planes, where we also need to enable BORDER_OUT. Signed-off-by: Rob Clark <robdclark@gmail.com>

Obviosuly this means that if individual planes need different tiling layouts and whatnot we will need a new modifier for each combination of planes with different tiling layouts. For a bit of extra backwards compatilbilty the kernel will allow non-zero modifier[1+] but it require that they will match modifier[0]. This in case there's existing userspace out there that sets modifier[1+] to something non-zero with planar formats.

We can simplify this tracking by using reference counting (at a cost of a few more atomics).

| * | | drm/msm: Fix error handling crashes seen when VRAM allocation failsArchit Taneja2016-11-042-3/+6

The following changes are made to fix this: msm_gem_shrinker_cleanup() is fixed to unregister the shrinker only if it was init-ed in the first place. Before calling kms->funcs->destroy(), we check if kms->funcs is also non-NULL. This is needed for MDP5, since during msm_drm_int(), priv->kms becomes non-NULL early, but msm_kms_init() is called on it only later in mdp5_kms_init().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the bottom-most layer is not fullscreen, we need to use the BASE mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT). The blend_setup() code pretty much handled this already, we just had to figure this out in _atomic_check() and assign the stages appropriately. Also fix the case where there are zero enabled planes, where we also need to enable BORDER_OUT. Signed-off-by: Rob Clark <robdclark@gmail.com>
| * | | drm/msm: Set CLK_IGNORE_UNUSED flag for PLL clocksArchit Taneja2016-11-024-0/+4

The clock framework doesn't have a mechanism at the moment where we can tie such resources to a clock, so we make sure that the KMS driver enables these resources whenever a PLL is expected to be in use. One place where we can't ensure the resource dependencies are met is when the clock framework tries to disable unused clocks. The KMS driver doesn't know when the clock framework calls the is_enabled clk_op, and hence can't enable interface clocks/power domains beforehand. We set the CLK_IGNORE_UNUSED flag for PLL clocks for now. This needs to be revisited, since bootloaders can enable display, and we would want to disable the PLL clocks if there isn't a display driver using them.
