2007-08-24ivtv: kzalloc() returns void pointer, no need to castHans Verkuil
From: Jesper Juhl <jesper.juhl@gmail.com> Since kzalloc() returns a void pointer, we don't need to cast the return value in drivers/media/video/ivtv/ivtv-queue.c Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-23ivtv: fix V4L2_ENC_CMD_STOP_AT_GOP_END supportHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Support for V4L2_ENC_CMD_STOP_AT_GOP_END was broken. While the driver correctly waited for the card to capture until the GOP was complete, afterwards the driver buffers were just flushed instead of waiting for the application to read all the pending data. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-23ivtv: fix VIDIOC_G_ENC_INDEX flag handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong frame types were filled in: the B and P frame types were swapped. This bug also hid a second bug: when a capture is stopped a last entry is written into the pgm index buffer with internal type 0, denoting the end of the program. This entry wasn't ignored, instead it was accidentally returned to the caller as a P frame. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-21cx2341x: some controls should not be changed while the device is busy.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The driver should now pass the 'busy' state of the device to the cx2341x module whenever controls are set or tried. -EBUSY will be returned if the device is busy and the user attempts to modify certain 'dangerous' controls. It concerns controls that change the audio or video compression mode and bitrates. The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy) to the cx2341x, effectively keeping the old behavior for now. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

Subject: ivtv: Fix static structure initialization Date: Thu, 23 Aug 2007 19:32:26 +0200 Convert the initialization of ivtv_i2c_algo_template to C99-style. Otherwise a future change to struct i2c_algo_bit_data would break this code. Also declared that structure const - it's a template after all.

From: Mauro Carvalho Chehab <mchehab@infradead.org> Since at least kernel 2.6.12-rc2, module.h includes moduleparm.h. This patch removes all occurences of moduleparm.h from drivers/media files. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-08-20ivtv: prevent changing VBI format while capture is in progress.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Changing the VBI format requires a CX2341X_ENC_INITIALIZE_INPUT firmware call. This can only be done if no capture is in progress. So return -EBUSY if the encoder is busy. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-20ivtv: fix output mode processing: UDMA_YUV wasn't cleared.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - Always clear when stopping the decoder - Clear if the filehandle that is being close was used for UDMA_YUV output. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-19ivtv: fix IVTV_IOC_DMA_FRAME bug introduced by highmem bugfix.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The return value of ivtv_udma_fill_sg_list() was changed by the highmem bugfix, but that return value was still used in ivtv-yuv.c. Revert to the old return value, but in addition return -1 in case of a memory allocation error. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-19ivtv: add support for highmem udmaHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When trying to DMA userspace buffers to the cx23415 you need to check whether the page is in highmem. If this is the case, then bounce buffers have to be used to allow DMA. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-19ivtv: move serialization to the fileops level.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Serialization is now done on the open/close/ioctl level and also when the read/write/poll start an encoder/decoder stream. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-19ivtv: specify some stream sizes in kB instead of MBHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Some streams (PCM, VBI decoding) do not need that much memory, so specify the allocated memory in kB instead of MB to limit memory usage. E.g. 1 MB is overkill for the VBI decoding stream, 64 kB is enough. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-19ivtv: setup TV output standard on init to prevent flickerHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The TV output standard was set only on first use, which meant that the saa7127 was set to NTSC until then, leading to flickering on PAL systems. Since the saa7127 has no firmware it is OK to initialize it immediately. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-18ivtv: fix udma yuv bugHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> Using udma yuv causes the driver becomes locked into that mode. This prevents use of the mpeg decoder & non-udma yuv output. This patch clears the operating mode when the device is closed. Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-18ivtv: fix VBI reinsertion decodingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - Invalid VBI packets should result in an empty VBI frame, not in an zero-sized frame that causes the reader to incorrectly return a 0 (EOF) value. - PIO completion should not reset the sg_pending_size field. - The DMA offset detection code should be ignored for PIO transfers: it somehow messes up the data on the card and is not needed anyway for PIO.

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>

2007-08-05ivtv: no need to mute the audio inputHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When changing channels the audio has to be muted. This is done by calling CX2341X_ENC_MUTE_AUDIO and by muted the audio input. The latter is not necessary and is now removed. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-08-03ivtv: attach yuv field order to each frameHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> In the current driver, the field order is global. As soon as it's changed it takes immediate effect. This is a problem when the video changes order mid stream. Although it mostly works okay, the video may judder / flicker. This patch attaches the field order to the frame, so that any buffered frames will not be displayed until the correct field. In the event that the field order is changed mid stream, the driver will ensure that the previous frame is displayed for a minimum of 3 fields. These are the two original fields the frame should have occupied, plus the one extra since the new frame still has to wait for the correct field.

2007-08-03ivtv: prevent yuv register updates from being missedHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> The yuv output code always compares the new frame position & size with those of the previous frame. If they are different, a flag is set to request the yuv output registers be updated when the new frame is displayed. If the incoming frames are delivered too fast, exhausting the buffers, the most recent frame already buffered will be discarded. Unfortunately, any update request will also be discarded. If the new frame matches the size & position of the now discarded frame, the yuv registers are not flagged for update & will remain in their old state. This patch preserves the register update flag in the event that a frame is dropped. Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
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.
