2007-07-13saa7146/dvb-ttpci: Fix signedness warnings (gcc 4.1.1, kernel 2.6.22)Oliver Endriss
From: Oliver Endriss <o.endriss@gmx.de> Fix signedness warnings (gcc 4.1.1, kernel 2.6.22). Signed-off-by: Oliver Endriss <o.endriss@gmx.de>
2007-04-22saa7146: Release capture buffers on device closeOliver Endriss
From: Hartmut Birr <e9hack@gmail.com> If the video device (saa7146 on a FF card) was open for capturing, the close call didn't release the capture buffers. Signed-off-by: Hartmut Birr <e9hack@gmail.com> Signed-off-by: Oliver Endriss <o.endriss@gmx.de>
2007-02-19compat: Add -include linux/version.h to cflagsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add -include linux/version.h to the cflags. Now code can have backward compatibility test without including compat.h first. Linux headers included from compat.h are removed, so that code will get the same headers when compiling in v4l-dvb as it does in the kernel. Many drivers have compat.h moved to the end of their include list, as this lets compat.h do things it can't do at the beginning. Such as test of something is defined to include compat code, or to put a wrapper around a function without changing the function's name. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2006-08-09[saa7146] Fixed image grabbing (VIDIOCGMBUF ioctl)Oliver Endriss
From: Oliver Endriss <o.endriss@gmx.de> Fixed regression reported by Peter Holik: Image grabbing failed because of invalid config option VIDEO_V4L1_COMPAT. Should be CONFIG_VIDEO_V4L1_COMPAT. Signed-off-by: Oliver Endriss <o.endriss@gmx.de>
2006-08-02V4L2 Conversion: saa5246a, saa5249, vino, hexium_orion, hexium_geminiMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Just a few adjustments were required on those drivers to be V4L2 compliant. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-04-11Kill drivers/media/common/saa7146_vv_ksyms.cMauro Carvalho Chehab
From: Adrian Bunk <bunk@stusta.de> This patch moves the EXPORT_SYMBOL's from drivers/media/common/saa7146_vv_ksyms.c to the files with the actual functions. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-03-10Make video_buf more genericMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Video_buf were concerned to allow PCI devices to be used as video capture devices. This patch extends video_buf features by virtualizing pci-dependent functions and allowing other type of devices to use it. It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-02-06sem2mutex: drivers/media/, #2Mauro Carvalho Chehab
Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.

2005-03-02whitespace cleanup (remove ws at eol, sync with changes in mainline kernel)Johannes Stezenbach
2004-11-21- prefix IER_DISABLE and IER_ENABLE with SAA7146_Johannes Stezenbach
- add SAA7146_ISR_CLEAR - use those consistently in the ttpci driver
2004-11-16 - videobuf api changes in 2.6.10Kenneth Aafloy
2004-11-16 - MODULE_PARM -> module_paramKenneth Aafloy
2004-10-26- add back support for older kernels due to popular demandMichael Hunold
2004-10-25- follow latest changes in 2.6.10-rc1 regarding video-buf. this changeMichael Hunold
breaks compilation with older kernels for dvb-ttpci
2004-07-31merge back various cleanups from mainline kernel:Johannes Stezenbach
- sparse annotiations (viro) - NULL noise removal (viro) - #if where #ifdef should've been (saa7146) (viro) - convert private ABS() to kernel's abs() (rddunlap) - dvb_register_i2c_device() locking fix for -ENOMEM (akpm) - dvb_register_i2c_bus() locking fix for -ENOMEM (akpm)
2004-07-28- rename memory to max_memory, because it clashes with some obscure ↵Michael Hunold
definition of memory on some esoteric platform
2004-06-18- apply cpu_to_le32() to all write operations concerning page tables, ↵Michael Hunold
necessary to support big-endian machines (thanks to Wolfram Joost)
2004-04-28- fix some ppc be endianess issues, overlay works fine, grabbing does not ↵Michael Hunold
work reliably yet, though
2004-03-19- copy & paste error: don't check for streaming capture twice, check for ↵Michael Hunold
overlay video in one case
2004-03-16- fix two debug messages (mixed up streaming capture and overlay)Michael Hunold
- restrict S_FBUF ioctl to CAP_SYS_ADMIN or CAP_SYS_RAWIO - don't refuse setting S_FBUF when overlay is active (changes become visible with the next update)
2004-03-15- code review of what's actually needed to be protected by a spinlock and by ↵Michael Hunold
the device lock - this fixes the "in_atomic():1, irqs_disabled():1" warnings in the syslog
2004-03-12With the addition of the ressource management, an overlay couldn't beMichael Hunold
interrupted by a streaming capture any more. So: - revamp video_begin()/video_end(), saa7146_start_preview()/saa7146_stop_preview - clean up a lot of mess around the usage of these functions - allow overlay to be suspended by streaming capture again, if ressources are available
2004-03-11- minor debug output cleanup in the resource handling functionsMichael Hunold
- deny activation of streaming capture if overlay is active, apps must disable overlay first - fix resource handling for overlay - don't try to stop streaming capture when it's not running

not work - make sure to disable the right video dma at capture stop
2004-01-14- bit masks are evil: disable the right video dma upon device close, otherwiseMichael Hunold
severe memory damage can occur...
2004-01-06fix build with 2.6.1-rc1-mm2 (VIDIOC_S_CTRL_OLD / VIDIOC_OVERLAY_OLD)Johannes Stezenbach

2004-01-03saa7146 driver improvements, only affects Video4Linux stuff:Michael Hunold
- add resource management functions - lock various stuff against each other, mostly vbi capture vs. planar capture formats, which use the same video dma - remove old commented out code - add new "flag" variable to saa7146_formats struct, store the information if a capture format is planar or packed - check for return codes at various places
2003-12-21- don't disable the capture engine via video_end() before video-buf hasMichael Hunold
cleared the various capture queue and has shut down capturing (Thanks Gerd for explaining the pitfalls here!)
2003-12-15- fix compilationMichael Hunold
- more video/vbi open/release fixes

2003-11-20- make saa7146_pgtable_build_single() deliver a return code, make someMichael Hunold
sanity checks of the arguments (if a bad pagetable is created, unpredictable thinks can happen. trust me... ;-) - follow this change for the several uses
2003-11-20- remove unnecessary "capture memory in framebuffer" special functionsMichael Hunold
which were commented out anyway - fix one typo
2003-10-09- backfeed patches from 2.6.0-test7, which have not gone through our cvs:Michael Hunold

2003-07-31Improvements regarding streaming capture to gfx card memory.Michael Hunold
2003-07-17[V4L] - fix static build for hexium_gemini and hexium_orion drivers (Thanks ↵Michael Hunold
to Adrian Bunk <bunk@fs.tum.de> for reporting this) [V4L] - set debug verbosity to 0 for hexium_gemini and hexium_orion drivers [V4L] - make hexium_gemini and hexium_orion drivers depdend on i2c module [V4L] - make saa7146 module depend on hexium_gemini and hexium_orion drivers [V4L] - let the saa7146 i2c bus report itself as I2C_ADAP_CLASS_TV_ANALOG
2003-07-07Make the "ext_vv_data" informations a per-device information insteadMichael Hunold
of a per-extension information. This is needed for the DVB-C cards, which seem to have swapped field order and need to propagate some video4linux specific stuff for the analog module to work.
