2011-03-22[media] s5p-fimc: fix ISR and buffer handling for fimc-captureSungchun Kang2-58/+45
In some cases fimc H/W did not stop although there were no output buffers available. So the capture deactivation interrupt routine is modified and the state of ST_CAPT_RUN is cleared only in the LAST-IRQ call. After LAST-IRQ is generated, H/W pointer will be skipped by 1 frame. (reference by user manual) So, S/W pointer should be increased too.

Two xc5000 tuners connected to same i2c bus. Experiments shows that situation when one tuner is not initialized while other is tuned to channel causes TS errors. Signed-off-by: Abylay Ospan <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2011-03-22[media] Fix CI code for NetUP Dual DVB-T/C CI RF cardAbylay Ospan1-4/+10
CI reset takes several seconds on some CAM, so there is no need to lock mutex all that time. Also we need not to preserve CI's reset bits in CIBUSCTRL register, they are handled automatically by FPGA. Set it to 0 explicitly in order to not reset wrong CAM.

2011-03-22[media] v4l: v4l2_subdev userspace format APILaurent Pinchart1-0/+49
Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

The pointer will later be used to register/unregister media entities when registering/unregistering a v4l2_subdev or a video_device. With the introduction of media devices, device drivers need to store a pointer to a driver-specific structure in the device's drvdata. v4l2_device can't claim ownership of the drvdata anymore. To maintain compatibility with drivers that rely on v4l2_device storing a pointer to itself in the device's drvdata, v4l2_device_register() will keep doing so if the drvdata is NULL.

2011-03-22[media] media: Pipelines and media streamsLaurent Pinchart1-0/+73
Drivers often need to associate pipeline objects to entities, and to take stream state into account when configuring entities and links. The pipeline API helps drivers manage that information. When starting streaming, drivers call media_entity_pipeline_start(). The function marks all entities connected to the given entity through enabled links, either directly or indirectly, as streaming. Similarly, when stopping the stream, drivers call media_entity_pipeline_stop(). The media_entity_pipeline_start() function takes a pointer to a media pipeline and stores it in every entity in the graph. Drivers should embed the media_pipeline structure in higher-level pipeline structures and can then access the pipeline through the media_entity structure. Link configuration will fail with -EBUSY by default if either end of the link is a streaming entity, unless the link is marked with the MEDIA_LNK_FL_DYNAMIC flag.

Userspace applications should enumerate entities using the MEDIA_ENT_ID_FLAG_NEXT flag.

However, the media_entity structure includes a use_count field that media drivers can use to track the number of users of every entity for power management needs.

2011-03-22[media] media: Entities, pads and linksLaurent Pinchart3-1/+204
As video hardware pipelines become increasingly complex and configurable, the current hardware description through v4l2 subdevices reaches its limits. In addition to enumerating and configuring subdevices, video camera drivers need a way to discover and modify at runtime how those subdevices are connected. This is done through new elements called entities, pads and links. An entity is a basic media hardware building block. It can correspond to a large variety of logical blocks such as physical hardware devices (CMOS sensor for instance), logical hardware devices (a building block in a System-on-Chip image processing pipeline), DMA channels or physical connectors. A pad is a connection endpoint through which an entity can interact with other entities. Data (not restricted to video) produced by an entity flows from the entity's output to one or more entity inputs. Pads should not be confused with physical pins at chip boundaries. A link is a point-to-point oriented connection between two pads, either on the same entity or on different entities. Data flows from a source pad to a sink pad. Links are stored in the source entity. To make backwards graph walk faster, a copy of all links is also stored in the sink entity. The copy is known as a backlink and is only used to help graph traversal. The entity API is made of three functions: - media_entity_init() initializes an entity. The caller must provide an array of pads as well as an estimated number of links. The links array is allocated dynamically and will be reallocated if it grows beyond the initial estimate. - media_entity_cleanup() frees resources allocated for an entity. It must be called during the cleanup phase after unregistering the entity and before freeing it. - media_entity_create_link() creates a link between two entities. An entry in the link array of each entity is allocated and stores pointers to source and sink pads. When a media device is unregistered, all its entities are unregistered automatically. The code is based on Hans Verkuil <[email protected]> initial work.

2011-03-22[media] media: Media device node supportLaurent Pinchart3-0/+339
The media_devnode structure provides support for registering and unregistering character devices using a dynamic major number. Reference counting is handled internally, making device drivers easier to write without having to solve the open/disconnect race condition issue over and over again. The code is based on video/v4l2-dev.c.

2011-03-22video: Fix EDID macros H_SYNC_WIDTH and H_SYNC_OFFSETMartin Decky1-2/+2
The macros for getting the values for horizontal sync width and offset do not respect the EDID specification. Both these values are 10 bit values according to [1], not 6 bit values. The lower 8 bits are stored in byte 8 and byte 9 of the DTD respectively, while two additional bits for each value are stored in byte 11. The original macros just slammed the bits together. Although the original macros usually worked fine because the higher two bits are rarely used, it can cause severe problems on plasma panels running at 1920x1080 @ 50 Hz with drivers that rely on the correct parsing of the EDID data by fbmon.c (e.g. udlfb). The patch should apply cleanly to both the fbdev-2.6.git branch and linux-next.git branch.

2011-03-22fbcon: Bugfix soft cursor detection in Tile BlittingHenry Nestler1-1/+1
Use mask 0x10 for "soft cursor" detection on in function tile_cursor. (Tile Blitting Operation in framebuffer console). The old mask 0x01 for vc_cursor_type detects CUR_NONE, CUR_LOWER_THIRD and every second mode value as "software cursor". This hides the cursor for these modes (cursor.mode = 0). But, only CUR_NONE or "software cursor" should hide the cursor. See also 0x10 in functions add_softcursor, bit_cursor and cw_cursor.
