2009-01-06cx88: Fix some Kbuild troublesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues: drivers/built-in.o: In function `cx88_call_i2c_clients': (.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend' drivers/built-in.o: In function `cx8802_probe': cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend' cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends' With those configs: CONFIG_VIDEO_CX88=y CONFIG_VIDEO_CX88_BLACKBIRD=y CONFIG_VIDEO_CX88_DVB=m CONFIG_DVB_CORE=m After carefully examining the code, with the current code, several cx88 drivers (cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module, if one of them is marked as such. Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.

From: Hans Verkuil <hverkuil@xs4all.nl> Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

2008-10-11S2API: Add Multiple-frontend on a single adapter support.darron@kewl.org
From: Steven Toth <stoth@linuxtv.org> A detailed description from the original patches 2 years ago: "The WinTV-HVR3000 has a single transport bus which is shared between a DVB-T and DVB-S modulator. These patches build on the bus acquisition cx88 work from a few weeks ago to add support for this. So to applications the HVR3000 looks like this: /dev/dvb/adapter0/fe0 (cx24123 DVB-S demod) /dev/dvb/adapter0/fe1 (cx22702 DVB-T demod) Additional boards continue as before, eg: /dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod) The basic change is removing the single instance of the videobuf_dvb in cx8802_dev and saa7134_dev(?) and replacing it with a list and some supporting functions. *NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so two or three current cx88 patches appear to be reversed by this tree, this will be cleaned up in the near future. The patches missing change the mutex handing to core->lock, fix an enumeration problem." It should be recognised that a number of people have been maintaining this patchset. Significant levels of Kudos to everyone one involved, including but not limited to: Darron Broad Fabio M. Di Nitto Carlo Scarfoglio Hans Werner Without the work of these people, and countless others, my two year old patches would of died on the Mercurial linuxtv.org vine a long time ago.

HISTORY (darron): This is the last update to MFE prepared by Hans which is based upon the `scratchpad' diff created by Carlo.

From: Jelle Foks <jelle@foks.8m.com> This patch should fix the 'muted audio' and 'raspy audio' problem for mpeg2 streams out of cx88-blackbird devices. Especially mythtv users would find that the audio would often sound bad (aliased, or 'raspy'), mainly related to channel changes, many (all?) other users would find that there was no audio at all in the mpeg data from the encoder chip, unless the audio was manually unmuted. The patch includes the following modifications: Don't actually start the mpeg2 encoder until the device is read from by the application. Wait until the audio is stable for at least 400ms before starting the mpeg encoder. Mute/Unmute the audio when starting/stopping the mpeg encoder. Stop the mpeg encoder when changing parameters and when changing tuner frequency. Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of whether or not the mpeg2 encoder is active.

2007-10-13cx88: Change (struct cx8802_dev)->drvlist to a list_head and fix bugsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> It was a struct cx8802_driver for no apparent reason. Nothing uses a cx8802_driver in the cx8802_dev struct. The only field that was used was devlist, a list_head. The code in cx8802_remove() that removed any loaded sub-drivers was broken. It would delete the current list entry, but didn't use list_for_each_safe. It also called list_del() on the list _head_ inside the list_for_each loop? It would crash if it was run, which I don't think can ever happen. Since the cx8802 sub-drivers use the cx8802 driver, they have to be unloaded first. So there isn't any way for a sub-driver to still be loaded when cx8802_remove() is called... Except maybe with PCI hot-plug, if one removes the PCI card while the drivers are loaded? So I left some code in to handle that if it's actually possible. It will remove the sub-drivers from the device cx8802_remove() was called on, and only that device. If one has two DVB cards and unplugs one, there is no reason to unload the DVB drivers for both cards. I have no way to test this, but it can't be worse than what was there before. cx8802_get_driver() is passed a cx8802_dev pointer and looks for the requested driver on that device. It first loops over the cx8802 device list looking for the device it was passed, which is pointless. It doesn't need to find the device pointer in the list, as it already has the pointer. The list_head in the cx8802_driver struct, which joins all the _drivers_ attached to a device, was named devlist. Changed that to drvlist, since the devlist is used for a list of _devices_ in other cx8802 structs. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Reviewed-by: Michael Krufky <mkrufky@linuxtv.org>

But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver. The reference in cx23885.h should just be removed, as the code there needs to be included if DVB is on or off. I do not think you can even compile the cx23885 driver without DVB.

2007-08-23cx88-alsa: Rework buffer handlingTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Rework the way the DMA buffer is handled and IRQs are generated. ALSA uses a ring-buffer of multiple periods. Each period is supposed to corrispond to one IRQ. The existing driver was generating one interrupt per ring-buffer, as opposed to per period. This meant that as soon as the IRQ was generated, the hardware was already starting to re-write the beginning of the buffer. Since the DMA happens on a per-line basis, there was only a narrow window to copy the data out before the buffer was overwritten. The cx88 core RISC program generator is modified so that it can set the IRQ and counter flags to count every X lines of DMA transfer. This way we can generate an interrupt every period instead of every full ring-buffer. Right now only period of one line are supported, but it should be possible to support longer periods. Note that a WRITE instruction generates an IRQ when it starts, not when the transfer is finished. Thus to generate an IRQ when line X is done, one must set the IRQ flag on the instruction that starts line X+1, not the one that ends line X. Change the line size so that there are four lines in the SRAM FIFO. If there are not four lines, the analog output from the cx88's internal DACs is full of clicks and pops. Try to handle FIFO sync errors. Sometimes the chip generates many of these errors before audio data starts. Up to 50 sync errors will be ignored and the counter reset. Have the IRQ handler save the RISC counter to the chip struct, and then have the pointer callback use this to calculate the pointer position. We could read the counter from the pointer callback, but sometimes the sync errors on start up cause the counter to go crazy. ALSA sees this and thinks there has been an overrun. The IRQ hander can avoid saving the counter position on sync errors. The chip "opened" flag wasn't necessary. ALSA won't try to open the same substream multiple times. Probably this code was cut&pasted from the bt87x driver, which has multiple sub-streams for one chip. Do error checking for the videobuf mapping functions. snd_card_cx88_runtime_free() is useless and can be deleted. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

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: Trent Piepho <xyzzy@speakeasy.org>
2007-08-15cx88: Copy board information into card stateTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> 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.

2007-08-13cx88: Make card database more memory efficientTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> 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: Trent Piepho <xyzzy@speakeasy.org>
