From: Michael Krufky <mkrufky@linuxtv.org> only #include <linux/freezer.h> #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,23) Signed-off-by: Michael Krufky <mkrufky@linuxtv.org>
2007-07-19backport kernel changeset 831441862956fffa17b9801db37e6ea1650b0f69Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> kernel-sync: Original patch description from the patch by Rafael J. Wysocki <rjw@sisk.pl>: Freezer: make kernel threads nonfreezable by default Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
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>
2006-12-18Fix broken audio mode handling for line-in in msp3400.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The wrong matrix was used when an external input was selected instead of the tuner input. The rxsubchans field was also not initialized to STEREO for an external input. And finally the msp34xxg_detect_stereo() should not try to detect stereo for an external input, that code is for the tuner input only. Together these bugs made it hit 'n miss whether you ever got stereo out of the msp3400 for an external input. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-10-02Reinstate dropped line to set standard detectionHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The previous patch accidentally dropped a crucial line to set the msp standard detection. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-10-01Fix msp343xG handling (regression from 2.6.16)Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The msp3430G and msp3435G models cannot do Automatic Standard Detection. So these should be forced to BTSC. These chips are early production versions for the msp34xxG series and are quite rare. The workaround for kernel 2.6.18 is to use 'standard=32' as msp3400 module option. Due to broken handling of the 'standard' option in 2.6.17 there is no workaround possible for that kernel. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-08-01Fix broken msp3400 module option 'standard'Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Due to a wrong statement order the 'standard' module option didn't work for 'G' model chips. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-04-02Improve line-in handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - improve handling of the EXTERN input: don't start an unnecessary carrier scan - improve the LOG_STATUS output - ensure that a carrier scan is started again when switching back to the tuner. - set correct prescale for L-NICAM Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-04-01Make msp3400 routing defines more consistentHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Renamed various msp3400 routing defines to be more consistent and less confusing. Esp. the MSP_DSP_OUT defines were confusing since it is really a DSP input. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-04-01Add back the msp_sleep that waits for the tuner to settle downHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> I removed a msp_sleep call that is really needed, otherwise the second carrier is not detected correctly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-04-01More msp3400 and bttv fixesHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - remove obsolete VIDIOC_S_INPUT i2c call in bttv - translate VIDIOCSFREQ to VIDIOC_S_FREQUENCY in i2c call - improve muting during carrier scan in msp3400 - don't start scan unless really needed. - no longer reset chip for msp3400c/d. - remove v4l2 check in tuner-core (radio stops after using the TV) - add missing VIDIOC_INT_ strings in v4l2-common.c Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-31Fix msp3400c and bttv stereo/mono/bilingual detection/handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - msp3400c did not detect the second carrier, thus being always mono. - properly mute the msp3400c while detecting the carrier. - fix checks on the presence of scart2/3 inputs and scart 2 output. - implement proper audio mode fallbacks for msp3400c/d, identical to the way msp3400g works. - MODE_STEREO no longer produces dual languages when set for a bilingual transmission, instead it falls back to LANG1. Use LANG1_LANG2 to hear both languages of a bilingual transmission. This is much more intuitive for the user and is in accordance with the preferred usage in the v4l2 specification. - bttv tried to implement v4l2 calls with v4l1 calls to the i2c devices, completely mangling the audmode/rxsubchans handling. v4l2 calls now do v4l2 calls to the i2c devices. - fixed broken i2c_vidiocschan in bttv. - add start/end lines to LOG_STATUS. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-29Fix msp3400c wait time and better audio mode fallbacksHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - The wait time until the first time the audio mode was detected was 1+5=6 seconds instead of just 1 second (wrong statement order). msp3400c specific bug. - Implemented audio mode fallback for msp3400c/d just like the msp3400g does automatically. E.g. fallback to stereo if no second language exists, etc. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-19Implement V4L2_TUNER_MODE_LANG1_LANG2 audio modeHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER). This mode allows the user to select both languages of a bilingual transmission, one language on the left, one on the right audio channel. If there is no bilingual transmission, or it is not supported, then this mode should act like V4L2_TUNER_MODE_STEREO. This mode is introduced for PVR-like drivers where it is useful to be able to record both languages of a bilingual broadcast. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-19Implement correct msp3400 input/output routingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - implement VIDIOC_INT_S_AUDIO_ROUTING for msp3400 and tvaudio - use the new command in bttv, pvrusb2 and em28xx. - remove the now obsolete MSP_SET_MATRIX from msp3400 (yeah!) - remove the obsolete VIDIOC_S_AUDIO from msp3400. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-19Add new media/msp3400.h header containing the routing macrosHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Moved msp3400.h to msp3400-driver.h. Created media/msp3400.h with the new routing defines and lots of comments. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-19Last round of msp3400 cleanups before adding routing commandsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Lots of cleanups: - remove duplicate actions - add D/K3 Dual FM-Stereo and D/K NICAM FM (HDEV3) support - put prescales in the proper place - add missing D/K NICAM - msp34xxg_reset now only resets instead of also starting the autodetect (moved that to msp34xxg_thread) - fix support for SAP. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-19Move msp_modus to msp3400-kthreads, add JP and KR std detectionHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> msp_modus is 'G' model specific. Moved it to kthreads and also added proper handling for the Japanese and South Korean TV standards. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-03-19Cleanup audio input handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Cleanup audio input handling in bttv and tvaudio: - inputs were specified that were never used - mute was handled as a special input which led to confusing code - confusing naming made it difficult to see if the setting was for i2c or gpio. The old audiochip.h input names moved to tvaudio.h. Currently this is used both by tvaudio and msp3400 until the msp3400 implements the new msp3400-specific inputs. Detect in bttv the tvaudio and msp3400 i2c clients and use these client pointers to set the inputs directly instead of broadcasting the command. Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be replaced again later by the new ROUTING commands. Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is a user level command and not to be used internally. It wasn't called at all anyway.

This mode allows the user to select both languages of a bilingual transmission, one language on the left, one on the right audio channel. If there is no bilingual transmission, or it is not supported, then this mode should act like V4L2_TUNER_MODE_STEREO.

2006-01-18Fix handling of VIDIOC_G_TUNER audmode in msp3400Hans Verkuil
Fix handling of VIDIOC_G_TUNER audmode in msp3400: audmode is only changed by the user with S_TUNER, never by the driver. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-01-11Fixes some bad global variablesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@brturbo.com.br> - debug global var is already used inside kernel. - v4l_dbg now expects the debug var - global vars inside msp34xx renamed to msp_* Signed-off-by: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
2006-01-08Fix stereo and standard reporting of msp3400 (esp. for radio)Hans Verkuil
- Add VIDIOC_LOG_STATUS to the radio device ioctl list. - Reduce the confusion between modes and standards - Fix stereo reporting for radio. - Don't set i2c configuration if the chip doesn't support it. - Fix reporting of current standard for radio. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-01-08msp3400 audio handling bug fixes.Hans Verkuil
- check capabilities for audio settings (volume, balance, bass, treble, loudness, mute) - added loudness support - added missing VIDEO_AUDIO_BALANCE flags for v4l1 compatibility - do not call msp_any_detect_stereo for non-autoselect chips to retrieve the current stereo setting: that will temporarily mute the sound. It is only needed when the stereo mode might be changed, and for autoselect msp processors that do not periodically need to update their stereo setting. - do not wake up the thread if the standard did not change. Prevents temporary audio drop-out if the standard is set to the same value. - fix confused stereo detect code where V4L2_TUNER_SUB_STEREO and V4L2_TUNER_MODE_STEREO values were used incorrectly. - stereo mode reporting was broken (v4l2 value used to index a string array expecting v4l1 mode values). - do not set dsp register 0x30 in the 3410d thread: that register does not exist for pre-'G' revision msp chips. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-01-08msp3400: use v4l2_std_id and determine chip capabilities.Hans Verkuil
- Replace old norm by the v4l2_std_id values. - Add code to correctly detect the various capabilities of the various msp chips. It's not yet used, that's going to be the next step. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-01-02Added new diagnositics macros, convert msp3400 to the new macros.Hans Verkuil
- Added new v4l_err, v4l_warn, v4l_info and v4l_dbg macros to v4l2-common.h for use in v4l-dvb i2c drivers. This ensures a unique prefix for each device instance. - At a later stage these macros may be reimplemented using the device-generic macros from device.h. - Converted the msp3400 driver to the new macros. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-01-02Split msp3400.c into msp3400-driver.c and msp3400-kthreads.cHans Verkuil
- Split msp3400.c into msp3400-driver.c and msp3400-kthreads.c. - Removed experimental DFPREG ioctls. If this is really needed one day then it should be implemented using VIDIOC_G/S_REGISTER. - Added missing BALANCE control info for VIDIOC_QUERYCTRL. - Still more cleanup, clarified some kernel messages.
