* media: v4l2-subdev: Provide const-aware subdev state accessorsLaurent Pinchart2024-06-041-18/+36
| | | | | | | | | | | | | | | | | | | | It would be useful to mark instances of v4l2_subdev_state structures as const when code needs to access them read-only. This isn't currently possible, as the v4l2_subdev_state_get_*() accessor functions take a non-const pointer to the state. Use _Generic() to provide two different versions of the accessors, for const and non-const states respectively. The former returns a const pointer to the requested format, rectangle or interval, implementing const-correctness. The latter returns a non-const pointer, preserving the current behaviour for drivers.

* media: subdev: Improve v4l2_subdev_enable/disable_streams_fallbackTomi Valkeinen2024-06-041-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | v4l2_subdev_enable/disable_streams_fallback() supports falling back to .s_stream() for subdevs with a single source pad. It also tracks the enabled streams for that one pad in the sd->enabled_streams field. Tracking the enabled streams with sd->enabled_streams does not make sense, as with .s_stream() there can only be a single stream per pad. Thus, as the v4l2_subdev_enable/disable_streams_fallback() only supports a single source pad, all we really need is a boolean which tells whether streaming has been enabled on this pad or not. However, as we only need a true/false state for a pad (instead of tracking which streams have been enabled for a pad), we can easily extend the fallback mechanism to support multiple source pads as we only need to keep track of which pads have been enabled. Change the sd->enabled_streams field to sd->enabled_pads, which is a 64-bit bitmask tracking the enabled source pads. With this change we can remove the restriction that v4l2_subdev_enable/disable_streams_fallback() only supports a single source pad.

* media: subdev: Fix use of sd->enabled_streams in call_s_stream()Tomi Valkeinen2024-06-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | call_s_stream() uses sd->enabled_streams to track whether streaming has already been enabled. However, v4l2_subdev_enable/disable_streams_fallback(), which was the original user of this field, already uses it, and v4l2_subdev_enable/disable_streams_fallback() will call call_s_stream(). This leads to a conflict as both functions set the field. Afaics, both functions set the field to the same value, so it won't cause a runtime bug, but it's still wrong and if we, e.g., change how v4l2_subdev_enable/disable_streams_fallback() operates we might easily cause bugs. Fix this by adding a new field, 's_stream_enabled', for call_s_stream().

| | | | | | | | | | | Subdev states store all standard pad configuration data, except for frame intervals. Fix it by adding interval fields in the v4l2_subdev_pad_config and v4l2_subdev_stream_config structures, with corresponding accessor functions and a helper function to implement the .get_frame_interval() operation.

* media: v4l2-subdev: Turn .[gs]_frame_interval into pad operationsLaurent Pinchart2023-12-132-12/+14
| | | | | | | | | | | | | | | | | | | | | | The subdev .[gs]_frame_interval are video operations, but they operate on pads (and even on streams). Not only is this confusing, it causes practical issues for drivers as the operations don't receive a subdev state pointer, requiring manual state handling. To improve the situation, turn the operations into pad operations, and extend them to receive a state pointer like other pad operations. While at it, rename the operations to .[gs]et_frame_interval at the same time to match the naming scheme of other pad operations. This isn't strictly necessary, but given that all drivers using those operations need to be modified, handling the rename separately would generate more churn for very little gain (if at all).

* media: v4l: subdev: Move out subdev state lock macros outside ↵Tomi Valkeinen2023-12-131-83/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_MEDIA_CONTROLLER The subdev state locking macros and macros to get the active state are currently behind CONFIG_MEDIA_CONTROLLER. This makes sense, as there can be no subdev state without MC. However, we have code paths common to MC and non-MC cases which call subdev operations that have subdev state as a parameter. In the non-MC case the state parameter would always be NULL. Thus it makes sense to allow, e.g.: v4l2_subdev_call_state_active(sd, pad, get_fmt, fmt) which for non-MC case would call the subdev passing NULL as the state. This currently fails: https://lore.kernel.org/oe-kbuild-all/202312061101.PLrz5NnJ-lkp@intel.com/ Fix the issue by moving the related macros to be outside CONFIG_MEDIA_CONTROLLER. The v4l2_subdev_lock_state() and v4l2_subdev_unlock_state() macros will crash if given NULL as the state, but the other macros behave correctly even when there's no active state, and they will only call the lock/unlock macros if there is a state. An alternative fix would be to make another version of v4l2_subdev_call_state_try() with ifdefs, which would not use any state macros and would always pass NULL as the state. But having two version of a macro/function is always more confusing than having just one, so I went this way. So, this fixes the v4l2_subdev_call_state_active() macro. But we also have v4l2_subdev_call_state_try(). It would be possible to fix that macro by additionally creating "no-op" variants of the state alloc and free functions. However, v4l2_subdev_call_state_try() is only used by a single driver (stm32-dcmi), which selects MC, and the macro is supposed to be removed as soon as the users have been converted away from the macro. Thus I have not touched the state alloc/free functions, and I think it makes sense to keep alloc/free functions available only if there's actually something that can be allocated or freed.

| | | | | | | | | | | | | | | | | | | | | | | | | The subdev .init_cfg() operation is affected by two issues: - It has long been extended to initialize a whole v4l2_subdev_state instead of just a v4l2_subdev_pad_config, but its name has stuck around. - Despite operating on a whole subdev state and not being directly exposed to the subdev users (either in-kernel or through the userspace API), .init_cfg() is categorized as a subdev pad operation. This participates in making the subdev API confusing for new developers. Fix it by renaming the operation to .init_state(), and make it a subdev internal operation.
