2007-08-03ivtv-fb: framebuffer timings no longer locked on module loadHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> Framebuffer timings are currently locked to the video format in use when the module is loaded. If the video format is then changed, the timings returned by the framebuffer will be for the original format. This patch ensures that the timings returned reflect the current video format.

2007-08-03ivtv: prevent vertical overflow of yuv outputHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> When the video standard is changed, there's no guarantee the framebuffer dimensions are still legal. The yuv output code uses these dimensions to calculate the size & position for the video overlay. If the framebuffer dimensions are now illegal, the output may exceed the vertical limit of the display, causing distortion. This patch adds an additional check to ensure the output doesn't exceed the limits for the current video standard, cropping if required.

2007-07-31cx88: Wrong values used for HD-3000 radio modeTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> After some tedious work with a logic probe and a magnifying glass, I've determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz IF output on pin 12 and the FM 10.7MHz If output on pin 11. GPIO 2 is used to switch the card's analog sound output from from the analog input connector to the CX23883's audio DACs. So, in radio mode GPIO2 = 1 and GPIO7 = 0. Add some comments about how the HD-3000's GPIOs are connected. Delete the vmux setting for the radio, as vmux doesn't apply to radio mode. Also delete the lines setting unused gpio words to zero; it's not necessary as 0 is the default value for uninitialized fields. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2007-07-29ivtv: Fix scatter/gather DMA timeoutsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> It turns out that the cx23415/6 DMA engine cannot do scatter/gather DMA reliably. Every so often depending on the phase of the moon and your hardware configuration the cx2341x DMA engine simply chokes on it and you have to reboot to get it working again. This change replaced the scatter/gather DMA by single transfers at a time, where the driver is now responsible for DMA-ing each buffer. UDMA is still done using scatter/gather DMA, that will be fixed soon. Many thanks to Mark Bryars <mark.bryars@etvinteractive.com> for discovering the link between scatter/gather and the DMA timeouts.

2007-07-28ivtv: always steal full frames if out of buffers.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When there are no more free buffers, then buffers are stolen from the predma queue. Buffers should be stolen from the head of that queue (which is where the most recently added buffers are) and all buffers belonging to a frame should be stolen. Otherwise 'half-frames' would remain in the queue, which leads to ugly playback and complete sync failure for YUV buffers. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-18ivtv: fix handling of INITIALIZE_INPUT fw callHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The CX2341X_ENC_INITIALIZE_INPUT firmware call requires careful handling, otherwise the computer can freeze or the top-third of the screen can start flickering. This patch ensures that CX2341X_ENC_INITIALIZE_INPUT is called at the right time and in the right way. In addition the stop capture handling was improved so that the last pending DMA transfer is also processed. Otherwise this would be the first data that arrived when a new capture was started which is not what you want. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-07-22ivtv: fix TV-out VBI handling, only reset on last close.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> While decoding (MPEG or YUV) is active or when VBI output is in use, then do not clear the VBI output of the saa7127. Only after the last user is gone can we clear it. This fixes the case where playback was stopped, another channel was chosen and playback was restarted, while /dev/vbi16 was used to set the WSS (widescreen) setting. Without this fix the WSS was reset on every stop instead of just keeping the last value. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-07-21bttv: Fix Viewcast Osprey 440 supportTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Various gpio and mux settings for the Osprey 440 weren't correct. Fix them and provide some documentation about how the gpios work. The osprey eeprom routine wasn't run for the 440, add it. It was also crap, re-written to be better. Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample rate is fixed at 32kHz, as the driver doesn't support different rates for digital input mode, though the card can select the rate from 32, 44.1, or 48 kHz via gpio. Setting the audio gain via ALSA isn't supported yet; a userspace tool that programs the X9221 via i2c-dev must be used. The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC used, resulting in extremely garbled sound. That is fixed in a followup patch.
