A volatile autocluster is a cluster of related controls where one\ncontrol is the control that toggles between manual and auto mode and the other\ncontrols are the values for the manual mode. For example autogain and gain,\nautoexposure and exposure, etc.\n\nIf the hardware lets you read out the automatically calculated manual values\nwhile in automode, then those manual controls should be marked volatile.\n\ngain value as calculated by the autogain circuitry, then you would mark the\ngain control as volatile (i.e. continuously changing).\n\nThe question in such use cases is what to do when switching from the auto\nmode to the manual mode. Should we switch to the last set manual values or\nshould the volatile values be copied and used as the initial manual values.\n\nFor example: suppose the mode is manual gain and gain is set to 5. Then\nautogain is turned on and the gain is set by the hardware to 2. Finally\nthe user switches back to manual gain. What should the gain be? 2 or 5?\n\nAfter a long discussion the decisions was made to keep the last value as\ncalculated by the auto mode (so 2 in the example above).\n\nThe reason is that webcams that do such things will adapt themselves to\nthe current light conditions and when you switch back to manual mode you\nexpect that you keep the same picture. If you would switch back to old\nmanual values, then that would give you a suddenly different picture,\nwhich is jarring for the user.\n\nAdditionally, this would be difficult to implement in applications that\nstore and restore the control values at application exit and start.\n\nIf you want to keep the old manual values when you switch from auto to\nmanual, then there would have to be a way for applications to get hold\nof those old values while in auto mode, but there isn\u0027t.\n\nSo this patch will do all the heavy lifting in v4l2-ctrls.c: if you go\nfrom auto mode to manual mode and the manual controls are volatile, then\ng_volatile_ctrl will be called to get the current values for the manual\ncontrols before switching to manual mode.\n\nSigned-off-by: Hans Verkuil \u003chans.verkuil@cisco.com\u003e\nAcked-by: Hans de Goede \u003chdegoede@redhat.com\u003e\nSigned-off-by: Mauro Carvalho Chehab \u003cmchehab@redhat.com\u003e\n" }, { "commit": "88365105d683187e02a4f75220eaf51fd0c0b6e0", "tree": "acbc18b9e8eb7f74630fb7fd709cb35eafd30f54", "parents": [ "74a45790861f659058e8f8b565d98e5a1fdd8440" ], "author": { "name": "Hans Verkuil", "email": "hans.verkuil@cisco.com", "time": "Fri Aug 26 07:35:14 2011 -0300" }, "committer": { "name": "Mauro Carvalho Chehab", "email": "mchehab@redhat.com", "time": "Wed Sep 21 09:52:21 2011 -0300" }, "message": "[media] v4l2-ctrls: replace is_volatile with V4L2_CTRL_FLAG_VOLATILE\n\nWith the new flag there is no need anymore to have a separate is_volatile\nfield.

Also, it now can be done beforehand.\n\nAnother change that was made was to so the try and set at the same time.\nBefore when S_TRY_EXT_CTRLS was called it would \u0027try\u0027 the controls first,\nand then it would \u0027set\u0027 them. The idea was that any \u0027try\u0027 errors would\nprevent the \u0027set\u0027 from happening, thus avoiding having partially set\ncontrol lists.\n\nHowever, this caused more problems than it solved because between the \u0027try\u0027\nand the \u0027set\u0027 changes might have happened, so it had to try a second time,\nand since actual controls with a try_ctrl op are very rare (and those that\nwe have just adjust values and do not return an error), I\u0027ve decided to\ndrop that two-stage approach and just combine try and set.\n\nSigned-off-by: Hans Verkuil \u003chans.verkuil@cisco.com\u003e\nSigned-off-by: Mauro Carvalho Chehab \u003cmchehab@redhat.com\u003e\n" }, { "commit": "f1e393de382af9b9bd2462a42bfa16b8c501d81b", "tree": "1135a4a27166d3947ebfcf2be171efa2d8cd3228", "parents": [ "77068d36d8b9e9902a89b4bb01011d41926f5420" ], "author": { "name": "Hans Verkuil", "email": "hans.verkuil@cisco.com", "time": "Mon Jun 13 19:24:17 2011 -0300" }, "committer": { "name": "Mauro Carvalho Chehab", "email": "mchehab@redhat.com", "time": "Wed Jul 27 17:53:31 2011 -0300" }, "message": "[media] v4l2-event/ctrls/fh: allocate events per fh and per type instead of just per-fh\n\nThe driver had to decide how many events to allocate when the v4l2_fh struct\nwas created. It was possible to add more events afterwards, but there was no\nway to ensure that you wouldn\u0027t miss important events if the event queue\nwould fill up for that filehandle.\n\nIn addition, once there were no more free events, any new events were simply\ndropped on the floor.\n\nFor the control event in particular this made life very difficult since\ncontrol status/value changes could just be missed if the number of allocated\nevents and the speed at which the application read events was too low to keep\nup with the number of generated events. The application would have no idea\nwhat the latest state was for a control since it could have missed the latest\ncontrol change.\n\nSo this patch makes some major changes in how events are allocated. Instead\nof allocating events per-filehandle they are now allocated when subscribing an\nevent. So for that particular event type N events (determined by the driver)\nare allocated. Those events are reserved for that particular event type.\nThis ensures that you will not miss events for a particular type altogether.\n\nIn addition, if there are N events in use and a new event is raised, then\nthe oldest event is dropped and the new one is added. So the latest event\nis always available.\n\nThis can be further improved by adding the ability to merge the state of\ntwo events together, ensuring that no data is lost at all. This will be\nadded in the next patch.\n\nThis also makes it possible to allow the user to determine the number of\nevents that will be allocated. This is not implemented at the moment, but\nwould be trivial.\n\nSigned-off-by: Hans Verkuil \u003chans.verkuil@cisco.com\u003e\nSigned-off-by: Mauro Carvalho Chehab \u003cmchehab@redhat.com\u003e\n" }, { "commit": "77068d36d8b9e9902a89b4bb01011d41926f5420", "tree": "4fde4974ce56e52acac5c7c8d873d300e946adcc", "parents": [ "523f46d6aba9dcb0a2d0fc474ca884e93a7cf198" ], "author": { "name": "Hans Verkuil", "email": "hans.verkuil@cisco.com", "time": "Mon Jun 13 18:55:58 2011 -0300" }, "committer": { "name": "Mauro Carvalho Chehab", "email": "mchehab@redhat.com", "time": "Wed Jul 27 17:53:31 2011 -0300" }, "message": "[media] v4l2-ctrls/event: remove struct v4l2_ctrl_fh, instead use v4l2_subscribed_event\n\nThe v4l2_ctrl_fh struct connected v4l2_ctrl with v4l2_fh so the control\nwould know which filehandles subscribed to it.
