* V4L/DVB (8913): cx18: Create cx18_ specific wrappers for all pci mmio ↵Andy Walls2008-10-12
| | | | | | | | | | | accessesors. cx18: Create cx18_ specific wrappers for all pci mmio accessesors. This is a first step in instrumenting all CX23418 PCI bus IO, to debug problems with accessing the CX23418's PCI memory mapped IO.

* V4L/DVB (8774): cx18: Have CX23418 release buffers at end of capture.Andy Walls2008-10-12
| | | | | | | | | | | | cx18: Have CX23418 release buffers at end of capture. The CX23418 reuses task handles so we need to have it release the buffers associated with a task handle at the end of a capture. If we don't, buffer ids used for one type of stream in the driver (MPEG, TS, PCM), could be used for another type of stream by the CX23418, if a previously used handle is assigned to a different type of stream. The driver would drop valid buffers when this happened. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (8773): cx18: Fix cx18_find_handle() and add error checkingAndy Walls2008-10-12
| | | | | | | | | | cx18: Fix cx18_find_handle() and add error checking. cx18_find_handle() did not find a good task handle and would use the invalid task handle under common conditions. Added a define for the invalid task handle and added error checking as well. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (8770): cx18: get rid of ununsed buffers stolen fieldAndy Walls2008-10-12
| | | | | | | | cx18: get rid of ununsed buffers stolen field. It's an unused holdover from ivtv. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (8523): v4l2-dev: remove unused type and type2 field from video_deviceHans Verkuil2008-07-27
| | | | | | | | | The type and type2 fields were unused and so could be removed. Instead add a vfl_type field that contains the type of the video device. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (8428): videodev: rename 'dev' to 'parent'Hans Verkuil2008-07-23
| | | | | | | | The field 'dev' is not the video device, but the parent of the video device. Rename accordingly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (8414): videodev/cx18: fix get_index bug and error-handling lock-upsHans Verkuil2008-07-20
| | | | | | | | | Fix a bug in get_index that was introduced earlier. Also fix two error handling lock-ups in videodev and cx18 that where found thanks to that bug. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (8104): cx18/ivtv: ioctl debugging improvementsHans Verkuil2008-07-20
| | | | | | | | | | Completely rely on the video_ioctl2 debugging facilities rather than doing it ourselves. Fill in some missing fields in ivtv with VIDIOC_G_FBUF. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (8082): cx18: convert to video_ioctl2()Andy Walls2008-07-20
| | | | | | | | | | | | cx18: convert driver to use video_ioctl2(). Pushed down ioctl debug messages and priority checks as well. Still left serialization lock in place for now. #if 0'ed out sliced vbi ioctl code for now. Patch heavily based on similar changes made to ivtv by Hans Verkuil.

* V4L/DVB (7931): cx18: allow for simultaneous digital and analog captureHans Verkuil2008-06-05
| | | | | | | | | | | The HVR-1600 can do both analog and digital capture at the same time. Due to a driver bug -EBUSY would be returned when attempting to setup an analog capture while a digital capture was already in progress. Separate the two internally.

* V4L/DVB (7854): cx18/ivtv: improve and fix out-of-memory handlingHans Verkuil2008-05-14
| | | | | | | | | - don't show kernel backtrace when the allocation of the buffers fails: the normal ivtv/cx18 messages are clear enough and the backtrace scares users. - fix cleanup after the buffer allocation fails (caused kernel panic).

* V4L/DVB (7786): cx18: new driver for the Conexant CX23418 MPEG encoder chipHans Verkuil2008-04-29
Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from Conexant for their support. I am in particular thankful to Hauppauge since without their help this driver would not exist. It should also be noted that Steve did the work to get the DVB part up and running. Thank you!
