+ * Some general notes on the atomic requirements of VIDIOC_G/TRY/S_EXT_CTRLS:
+ *
+ * It is not a fully atomic operation, just best-effort only. After all, if
+ * multiple controls have to be set through multiple i2c writes (for example)
+ * then some initial writes may succeed while others fail. Thus leaving the
+ * system in an inconsistent state. The question is how much effort you are
+ * willing to spend on trying to make something atomic that really isn't.
+ *
+ * From the point of view of an application the main requirement is that
+ * when you call VIDIOC_S_EXT_CTRLS and some values are invalid then an
+ * error should be returned without actually affecting any controls.
+ *
+ * If all the values are correct, then it is acceptable to just give up
+ * in case of low-level errors.
+ *
+ * It is important though that the application can tell when only a partial
+ * configuration was done. The way we do that is through the error_idx field
+ * of struct v4l2_ext_controls: if that is equal to the count field then no
+ * controls were affected. Otherwise all controls before that index were
+ * successful in performing their 'get' or 'set' operation, the control at
+ * the given index failed, and you don't know what happened with the controls
+ * after the failed one. Since if they were part of a control cluster they
+ * could have been successfully processed (if a cluster member was encountered
+ * at index < error_idx), they could have failed (if a cluster member was at
+ * error_idx), or they may not have been processed yet (if the first cluster
+ * member appeared after error_idx).
+ *
+ * It is all fairly theoretical, though. In practice all you can do is to
+ * bail out. If error_idx == count, then it is an application bug. If
+ * error_idx < count then it is only an application bug if the error code was
+ * EBUSY. That usually means that something started streaming just when you
+ * tried to set the controls. In all other cases it is a driver/hardware
+ * problem and all you can do is to retry or bail out.
+ *
+ * Note that these rules do not apply to VIDIOC_TRY_EXT_CTRLS: since that
+ * never modifies controls the error_idx is just set to whatever control
+ * has an invalid value.

-/* Some general notes on the atomic requirements of VIDIOC_G/TRY/S_EXT_CTRLS:
-
- It is not a fully atomic operation, just best-effort only. After all, if
- multiple controls have to be set through multiple i2c writes (for example)
- then some initial writes may succeed while others fail. Thus leaving the
- system in an inconsistent state. The question is how much effort you are
- willing to spend on trying to make something atomic that really isn't.
-
- From the point of view of an application the main requirement is that
- when you call VIDIOC_S_EXT_CTRLS and some values are invalid then an
- error should be returned without actually affecting any controls.
-
- If all the values are correct, then it is acceptable to just give up
- in case of low-level errors.
-
- It is important though that the application can tell when only a partial
- configuration was done. The way we do that is through the error_idx field
- of struct v4l2_ext_controls: if that is equal to the count field then no
- controls were affected. Otherwise all controls before that index were
- successful in performing their 'get' or 'set' operation, the control at
- the given index failed, and you don't know what happened with the controls
- after the failed one. Since if they were part of a control cluster they
- could have been successfully processed (if a cluster member was encountered
- at index < error_idx), they could have failed (if a cluster member was at
- error_idx), or they may not have been processed yet (if the first cluster
- member appeared after error_idx).
-
- It is all fairly theoretical, though. In practice all you can do is to
- bail out. If error_idx == count, then it is an application bug. If
- error_idx < count then it is only an application bug if the error code was
- EBUSY. That usually means that something started streaming just when you
- tried to set the controls. In all other cases it is a driver/hardware
- problem and all you can do is to retry or bail out.
-
- Note that these rules do not apply to VIDIOC_TRY_EXT_CTRLS: since that
- never modifies controls the error_idx is just set to whatever control
- has an invalid value.
