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:

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:

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:

- 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.

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.

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:

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:

There are now 4 different versions of the GENPIX USB adapter. The newest 'Skywalker' models are fully self-contained, and need no additional hardware to be used. A very reliable DVB-S card even without using any of the alternate modulatations (which this kernel module does not currently support) The following patch adds support for all 4 versions of the genpix adapter (www.genpix-electronics.com).

FM radio transmission use a preemphasis/deemphasis scheme to reduce high-frequency noise. The cx88 audio decoder is supposedly set to no deemphasis by the current driver. However, the "no deemphasis" setting doesn't work. On my chip, cx23883, it produces the same result as the 75 us time constant. Maybe the default settings on the cx23881 are for 50 us? Since the deemphasis time constant varies by country, allow setting it via a module parameter. Signed-off-by:

The first part of dvb_net_close() is just a cut&paste from dvb_generic_release(), so maybe it would be better to just call dvb_generic_release() instead? Signed-off-by:

Get rid of the "CORE" prefix from cx88 printks. It was only used a few times, and it makes it look like they're coming from the kernel core or something. Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a "cx88[0]" prefix to be consistent, and to keep people who grep their dmesg output for cx88 from missing it. Get rid of the addresses, which are always wrong. The addresses are always set to -1, but because it's an unsigned 8-bit value, the left shift converts it to the nonsense address 0x1fe. In the cx8802 driver, some cut and pasted code prefixed lines with "CORE cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from the cx8802 driver. Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for KERN_INFO and KERN_ERR messages. The changed printks in cx88-mpeg.c also needed lots of whitespace and 80-column fixes. A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels or a consistent "cx88[?]/2" or "cx88[?]/0" prefix. Signed-off-by:

A lot of code in cx88-cards.c was only used by cx88-core.c when the core state is first allocated and initialized. Moving that task to cx88-cards makes the driver simpler and the files more self contained. - Module parameters tuner, radio, card, and latency move to cx88-cards.c - cx88_boards is made static - cx88_subids is made static and const - cx88_bcount is eliminated - cx88_idcount is eliminated - cx88_card_list() is made static - cx88_card_setup_pre_i2c() is made static - cx88_card_setup() is made static - cx88_pci_quirks() is moved from cx88-core to cx88-cards The function argument "char *name" is made const too - get_ressources() is moved from cx88-core to cx88-cards, and renamed to cx88_get_resources() - The code to allocate and initialize the core state struct and the chip is moved out of cx88-core.c:cx88_get_core() and into a new function in cx88-cards.c, cx88_core_create(). This makes both functions simpler. Signed-off-by:

The cx88 driver state stored the ID of the board type in core->board. Every time the driver need to get some information about the board configuration, it uses the board number as an index into board configuration array. This patch changes it so that the board number is in core->boardnr, and core->board is a copy of the board configuration information. This allows access to board information without the extra indirection. e.g. cx88_boards[core->board].mpeg becomes core->board.mpeg. This has a number of advantages: - The code is simpler to write. - It compiles to be smaller and faster, without needing the extra array lookup to get at the board information. - The cx88_boards array no longer needs to be exported to all cx88 modules. - The boards array can be made const - It should be possible to avoid keeping the (large) cx88_boards array around after the module is loaded. - If module parameters or eeprom info override some board configuration setting, it's not necessary to modify the boards array, which would affect all boards of the same type.

An error message for PCI resource allocation failure used the board type before it was set. Just get rid of the error message, as get_ressources() [sic] already prints one. Format that error message better, and add the pci function and subsystem information to better associate the error with what caused it. Signed-off-by:

The vmux setting is only two bits, but was taking up a whole 32 in the input description struct. By changing it to a two-bit bitfield, it can fit in what was padding space before and drop the input size by 4 bytes, from 28 to 24. This drops the board description struct, which has 9 inputs, from 280 to 244 bytes. Total driver size decreases by 2108 bytes. Signed-off-by:

Audio muting for the tuner input was implemented by stopping the audio microcontroller and restarting it on unmute. However, it appears that this method can actually crash the audio firmware. It's rare and seems to happen with NTSC only. It has been reimplemented by setting to volume to 0. In addition, the reporting of the mute state has been improved as well: it used to be impossible to detect whether the audio was muted by the user or if it was muted due to the microcontroller trying to detect the audio standard. This is now clearly stated. Signed-off-by:
