Both Hauppauge WinTV 44981 (bt878) and the HVR 1110 (saa7134) have a Zilog Z8F0811. The transmitter was not probed. Receive and transmit tested on both cards. Signed-off-by:

The raw_register function exists to create input devices associated with that IR protocol. If the mce_kbd module is loaded, then every rc device will have mce_kbd input devices, even if the protocol is not enabled. Change this to call the register function to when the protocol is enabled.

Some VSP instances have two blending units named BRU (Blend/ROP Unit) and BRS (Blend/ROP Sub unit). The BRS is a smaller version of the BRU with only two inputs, but otherwise offers similar features and offers the same register interface. The BRU and BRS can be used exchangeably in VSP pipelines (provided no more than two inputs are needed). Due to historical reasons, the VSP1 driver implements support for both the BRU and BRS through objects named vsp1_bru. The code uses the name BRU to refer to either the BRU or the BRS, except in a few places where noted explicitly. This creates confusion. In an effort to avoid confusion, rename the vsp1_bru object and the corresponding API to vsp1_brx, and use BRx to refer to blend unit instances regardless of their type. The names BRU and BRS are retained where reference to a particular blend unit type is needed, as well as in hardware registers to stay close to the datasheet. Signed-off-by:

Dynamic assignment of the BRU and BRS to pipelines is prone to regressions, add messages to make debugging easier. Keep it as a separate commit to ease removal of those messages once the code will deem to be completely stable. Signed-off-by:

The VSPDL variant drives two DU channels through two LIF and two blenders, BRU and BRS. The DU channels thus share the five available VSPDL inputs and expose them as five KMS planes. The current implementation assigns the BRS to the second LIF and thus artificially limits the number of planes for the second display channel to two at most. Lift this artificial limitation by assigning the BRU and BRS to the display pipelines on demand based on the number of planes used by each pipeline. When a display pipeline needs more than two inputs and the BRU is already in use by the other pipeline, this requires reconfiguring the other pipeline to free the BRU before processing, which can result in frame drop on both pipelines.

When disabling a DRM plane, the corresponding RPF is only marked as removed from the pipeline in the atomic update handler, with the actual removal happening when configuring the pipeline at atomic commit time. This is required as the RPF has to be disabled in the hardware, which can't be done from the atomic update handler. The current implementation is RPF-specific. Make it independent of the entity type by using the entity's pipe pointer to mark removal from the pipeline. This will allow using the mechanism to remove BRU instances. Signed-off-by:

Display list completion is already reported to the frame end handler, but that mechanism is global to all display lists. In order to implement BRU and BRS reassignment in DRM pipelines we will need to commit a display list and wait for its completion internally, without reporting it to the DRM driver. Extend the display list API to support such an internal use of the display list. Signed-off-by:

We will soon need to return more than a boolean completion status from the vsp1_dlm_irq_frame_end() IRQ handler. Turn the return value into a bitfield to prepare for that. No functional change is introduced here. Signed-off-by:

In order to make the vsp1_du_setup_lif() easier to read, and for symmetry with the DRM pipeline input setup, move the pipeline output setup code to a separate function. Signed-off-by:
-
Laurent Pinchart authored
The vsp1_du_setup_lif() function sets up the DRM pipeline input manually. This duplicates the code from the vsp1_du_pipeline_setup_inputs() function. Replace the manual implementation by a call to the function. As the pipeline has no enabled input in vsp1_du_setup_lif(), the vsp1_du_pipeline_setup_inputs() function will not setup any RPF, and will thus not setup formats on the BRU sink pads. This isn't a problem as all inputs are disabled, and the BRU sink pads will be reconfigured from the atomic commit handler when inputs will be enabled. Signed-off-by:

To implement fully dynamic plane assignment to pipelines, we need to reassign the BRU and BRS to the DRM pipelines in the atomic commit handler. In preparation for this setup factor out the BRU source pad code and call it both at LIF setup and atomic commit time. Signed-off-by:

The DRM pipeline handling code uses the entity's pipe list head to check whether the entity is already included in a pipeline. This method is a bit fragile in the sense that it uses list_empty() on a list_head that is a list member. Replace it by a simpler check for the entity pipe pointer. Signed-off-by:

The DRM support code manages a pipeline of VSP entities, each backed by a media entity. When starting or stopping the pipeline, it starts and stops the media pipeline through the media API in order to store the pipeline pointer in every entity. The driver doesn't use the pipe pointer in media entities, neither does it rely on the other effects of the media_pipeline_start() and media_pipeline_stop() functions. Furthermore, as the media links for the DRM pipeline are never set up correctly, and as the pipeline can be modified dynamically when enabling or disabling planes, the current implementation is not correct. Remove the incorrect and unneeded code. While at it remove the outdated comment that states that entities are not started when the LIF is setup, as they now are. Signed-off-by:

Depending on the chosen standard, configure the decoder to use the appropriate color encoding standard (PAL-like, NTSC-like or SECAM). Until now, the decoder was not configured for a specific color standard, making it autodetect the color encoding. While this may sound fine, it potentially causes the wrong image tuning parameters to be applied (e.g. tuning parameters for NTSC are applied to a PAL source), and may confuse users about what the actual standard is in use. This commit explicitly configures the color standard the decoder will use, making it visually obvious if a wrong standard was chosen. Signed-off-by:

The user-supplied norm value gets overwritten by the generic .norm member from the norm_params. That way, we lose the specific norm the user may want to set. For instance, if the user specifies V4L2_STD_PAL_60, the value actually used will be V4L2_STD_525_60, which in the end will be as if the user had specified V4L2_STD_NTSC, since this is always the first bitfield we match the norm value against before configuring the hardware. The norm_params array is only there to match a norm with an output resolution. The norm value itself should not be changed. Signed-off-by:

Make use of the V4L2_STD_525_60 and V4L2_STD_625_50 defines to determine the vertical resolution to use when capturing. V4L2_STD_525_60 (resp. V4L2_STD_625_50) is the set of standards using 525 (resp. 625) lines per frame, independently of the color encoding. Signed-off-by:

I've noticed that decoding fails sometime if size of bitstream buffer isn't aligned to 16K, probably because HW fetches data from memory in a 16K granularity and if the last chunk of data isn't aligned, HW reads garbage data beyond the dmabuf and tries to parse it. Signed-off-by:

Drivers that depend on ISAPNP currently can't be built with COMPILE_TEST. However, looking at isapnp.h, there are already stubs there to allow drivers to include it even when isa PNP is not supported. So, remove such dependencies when COMPILE_TEST. Acked-by:
