Make use of ARCH_RENESAS in place of ARCH_SHMOBILE. This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs. Acked-by:

The maximum image size supported by the WPF is 2048x2048 on Gen2 and 8190x8190 on Gen3. Update the code accordingly, and fix the maximum LIF size for both Gen2 and Gen3. Signed-off-by:

The format is erroneously defined with an alpha channel. Fix it. Signed-off-by:

Make the global alpha multiplier of DRM planes configurable. All the necessary infrastructure is there, we just need to store the alpha value passed through the DRM API. Signed-off-by:

Make the Z-order of planes configurable by assigning RPFs to BRU inputs dynamically based on the Z-order position. Signed-off-by:

Laurent Pinchart authored
The Gen3 RPF includes an alpha multiplier that can both multiply the alpha channel by a fixed global alpha value, and multiply the pixel components to convert the input to premultiplied alpha. As alpha premultiplication is available in the BRU for both Gen2 and Gen3 we handle it there and use the Gen3 alpha multiplier for global alpha multiplication only. This prevents conversion to premultiplied alpha if no BRU is present in the pipeline, that use case will be implemented later if needed. Signed-off-by:

Synchronize the userspace LUT setup with the pipeline operation by using a display list fragment to store LUT data. Signed-off-by:

Display lists support up to 8 bodies but we currently use a single one. To support preparing display lists for large look-up tables, add support for multi-body display lists. Signed-off-by:

The vsp1_dl_list_put() function expects to be called with the display list manager lock held. This assumption is correct for calls from within the vsp1_dl.c file, but not for the external calls. Fix it by taking the lock inside the function and providing an unlocked version for the internal callers. Signed-off-by:

There are some issues rised on this patch during patch review. I ended by merging this one by mistake. So, let's revert it. This reverts commit 54ace1cf. Cc: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by:

All entities implement the same get pad format handler, factorize it into a common function. Signed-off-by:

The RPF entities are located at the very beginning of pipelines, they can't be target nodes in the Data Path Router matrix. Remove their input ID from the routing table. Signed-off-by:

Instead of embedding pipelines in the vsp1_video objects allocate them on demand when they are needed. This fixes the streamon race condition where pipelines objects from different video nodes could be used for the same pipeline. Signed-off-by:

Move the pipeline initialization and cleanup functions to prepare for the next commit. No functional code change is performed here. Signed-off-by:

This prepares for dynamic pipeline allocation by providing a field that can be used to store the pipeline pointer atomically under driver control. Signed-off-by:

Pass the pipe explicitly instead of retrieving it through media entities. This decouples device state stored in the pipeline from the active state stored in entities, preparing for dynamic pipeline creation. Signed-off-by:

The primary purpose of those functions is to build the pipeline, rename them to make this clearer. Signed-off-by:

Laurent Pinchart authored
Modules write register values to the active display list pointed to by the pipeline. In order to support preparing display lists ahead of time, pass them explicitly to all configuration functions. Signed-off-by:

Reuse the runtime logic to initialize the default format instead of open-coding it. This ensures coherency between intialization and runtime. Signed-off-by:

The two structures are identical, merge them and move the result to vsp1_rwpf.c. All rwpf pad operations can now be declared static. Signed-off-by:

Laurent Pinchart authored
The subdev s_stream operation is abused as a generic way to setup modules at every frame. Move the code out to a new VSP1 entity configure operation. Most modules now have an empty s_stream operation that can be removed. The only exception is the WPF module that needs to perform hardware configuration when stopping the stream. The code can be simplified accordingly as we know that that operation never fails. Signed-off-by:

Use the pad config structure part of the vsp1_entity to store all active pad selection rectangles. This generalizes the code to operate on pad config structures. Signed-off-by:

Add a pad config structure field to the vsp1_entity structure and use it to store all active pad formats. This generalizes the code to operate on pad config structures. Signed-off-by:
-
Laurent Pinchart authored
Turn the custom formats initialization function into a standard pad::init_cfg handler and use it in subdevs instead of initializing formats in the subdev open handler. This makes the subdev open handler empty, so remove it. Signed-off-by:

Laurent Pinchart authored
Entities have two operations, a destroy operation stored directly in vsp1_entity and a set_memory operation stored in a vsp1_rwpf_operations structure. Move the two to a more generic vsp1_entity_operations structure that will serve to implement additional operations. Signed-off-by:

Don't duplicate the code in every module driver, centralize it in a single place. Signed-off-by:

Don't restrict display list usage to the DRM pipeline, use them unconditionally. This prepares the driver to support the request API. Signed-off-by:

Laurent Pinchart authored
Display lists can operate in header or headerless mode. The headerless mode is only available on WPF0, to be used with the display engine. All other WPF instances can only use display lists in header mode. Implement support for header mode to prepare for display list usage on WPFs other than 0. Signed-off-by:

Commit f7234138 ("v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config") introduced lots of 80 characters per line violations. Fix them. Signed-off-by:

The function can only be called from a s_stream handler as it requires a valid display list context (due to calling vsp1_uds_set_alpha() which writes to module registers). Document the requirement. Signed-off-by:

The RPF source memory pointers need to be offset to take the crop rectangle into account. Offsets are computed in the RPF stream start, which can happen (when using the DRM pipeline) after calling the RPF .set_memory() operation that programs the buffer addresses. The .set_memory() operation tries to guard against the problem by skipping programming of the registers when the module isn't streaming. This will however only protect the first use of an RPF in a DRM pipeline, as in all subsequent uses the module streaming flag will be set and the .set_memory() operation will use potentially incorrect offsets. Fix this by allowing the caller to decide whether to program the hardware immediately or just cache the addresses. While at it refactor the memory set code and create a new vsp1_rwpf_set_memory() that cache addresses and calls the .set_memory() operation to apply them to the hardware. As a side effect the driver now writes all three DMA address registers regardless of the number of planes, and initializes unused addresses to zero. Signed-off-by:

Those modules were left out of display list integration as they're not used by the DRM pipeline. To prepare for display list support in non-DRM pipelines use the module write API to set registers. Signed-off-by:

The control handler set operations don't program the hardware anymore, there's thus no need to call them when starting the stream. Signed-off-by:
