charset=UTF-8 Content-Transfer-Encoding: 8bit With the current matching rules the lookup for rc protocol named rc-5-sz matches with "rc-5" before finding "rc-5-sz". Thus one is able to never enable/disable the rc-5-sz protocol via sysfs. Fix the lookup to require an exact match which allows the manipulation of sz protocol.

I came across a post from Andy in March (http://www.gossamer-threads.com/lists/ivtv/users/40943#40943) where he speculates that perhaps the corrective actions being taken after a DMA ERROR are not sufficient to recover the situation. After some testing I suspect that this is indeed the case, and that in fact the corrective action may be what hangs the card's DMA engine, rather than the original error. Specifically these DMA ERROR IRQs seem to present with two different values in the IVTV_REG_DMASTATUS register: 0x11 and 0x13. The current corrective action is to clear that status register back to 0x01 or 0x03, and then issue the next DMA request. In the case of a 0x13 this seems to result in a minor glitch in the encoded stream due to the failed transfer that was not retried, but otherwise things continue OK. In the case of a 0x11 the card's DMA write engine is never heard from again, and a DMA TIMEOUT follows shortly after. 0x11 is the killer. I suspect that the two cases need to be handled differently. The difference is in bit 1 (0x02), which is set when the error is about to be successfully recovered, and clear when things are about to go bad. Bit 1 of DMASTATUS is described differently in different places either as a positive "write finished", or an inverted "write busy". If we take the first definition, then when an error arises with state 0x11, it means that the write did not complete. It makes sense to start a new transfer, as in the current code. But if we take the second definition, then 0x11 means "an error but the write engine is still busy". Trying to feed it a new transfer in this situation might not be a good idea. As an experiment, I added code to ignore the DMA ERROR IRQ if DMASTATUS is 0x11. I.e., don't start a new transfer, don't clear our flags, etc. The hope was that the card would complete the transfer and issue a ENC DMA COMPLETE, either successfully or with an error condition there. However the card still hung. The only remaining corrective action being taken with a 0x11 status was then the write back to the status register to clear the error, i.e. DMASTATUS = DMASTATUS & ~3. This would have the effect of clearing the error bit 4, while leaving the lower bits indicating DMA write busy. Strangely enough, removing this write to the status register solved the problem! If the DMA ERROR IRQ with DMASTATUS=0x11 is completely ignored, with no corrective action at all, then the card will complete the transfer and issue a new IRQ. If the status register is written to when it has the value 0x11, then the DMA engine hangs. Perhaps it's illegal to write to DMASTATUS while the read or write busy bit is set? At any rate, it appears that the current corrective action is indeed making things worse rather than better. I put together a patch that modifies ivtv_irq_dma_err to do the following: - Don't write back to IVTV_REG_DMASTATUS. - If write-busy is asserted, leave the card alone. Just extend the timeout slightly. - If write-busy is de-asserted, retry the current transfer. This has completely fixed my DMA TIMEOUT woes. DMA ERR events still occur, but now they seem to be correctly handled. 0x11 events no longer hang the card, and 0x13 events no longer result in a glitch in the stream, as the failed transfer is retried. I'm happy. I've inlined the patch below in case it is of interest. As described above, I have a theory about why it works (based on a different interpretation of bit 1 of DMASTATUS), but I can't guarantee that my theory is correct. There may be another explanation, or it may be a fluke. Maybe ignoring that IRQ entirely would be equally effective? Maybe the status register read/writeback sequence is race condition if the card changes it in the mean time? Also as I am using a PVR-150 only, I have not been able to test it on other cards, which may be especially relevant for 350s that support concurrent decoding. Hopefully the patch does not break the DMA READ path. Mike [awalls@md.metrocast.net: Modified patch to add a verbose comment, make minor brace reformats, and clear the error flags in the IVTV_REG_DMASTATUS iff both read and write DMA were not in progress. Mike's conjecture about a race condition with the writeback is correct; it can confuse the DMA engine.] [Comment and analysis from the ML post by Michael ] Signed-off-by: Andy Walls Cc: stable@kernel.org Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/ivtv/ivtv-irq.c | 58 ++++++++++++++++++++++++++++++++----- 1 file changed, 51 insertions(+), 7 deletions(-) (limited to 'drivers/media') diff --git a/drivers/media/video/ivtv/ivtv-irq.c b/drivers/media/video/ivtv/ivtv-irq.c index 9b4faf00919..9c29e964d40 100644 --- a/drivers/media/video/ivtv/ivtv-irq.c +++ b/drivers/media/video/ivtv/ivtv-irq.c @@ -628,22 +628,66 @@ static void ivtv_irq_enc_pio_complete(struct ivtv *itv) static void ivtv_irq_dma_err(struct ivtv *itv) { u32 data[CX2341X_MBOX_MAX_DATA]; + u32 status; del_timer(&itv->dma_timer); + ivtv_api_get_data(&itv->enc_mbox, IVTV_MBOX_DMA_END, 2, data); + status = read_reg(IVTV_REG_DMASTATUS); IVTV_DEBUG_WARN("DMA ERROR %08x %08x %08x %d\n", data[0], data[1], - read_reg(IVTV_REG_DMASTATUS), itv->cur_dma_stream); - write_reg(read_reg(IVTV_REG_DMASTATUS) & 3, IVTV_REG_DMASTATUS); + status, itv->cur_dma_stream); + /* + * We do *not* write back to the IVTV_REG_DMASTATUS register to + * clear the error status, if either the encoder write (0x02) or + * decoder read (0x01) bus master DMA operation do not indicate + * completed.

If we probe the wrong address, probe fails and we have a non-working device. We have the actual address passed into the function by way of i2c_props, we just need to use it. Also fix up some copy/paste comment issues and streamline debug spew a touch. Verified to restore my HVR-1950 to full working order. Special thanks to Ken Bass for reporting the issue in the first place, and to both he and Gary Buhrmaster for aiding in debugging and analysis of the problem.

The development was sponsored by Technisat. The Green led is toggle depending on the frontend-state. The Red LED is turned on all the time. The MAC address reading from the EEPROM along with the LRC-method to check whether its valid. Support for the IR-receiver of the Technisat USB2 box. The keys of small, black remote-control are built-in, repeated key behaviour are simulated. The i2c-mutex of the dvb-usb-structure is used as a general mutex for USB requests, as there are 3 threads racing for atomic requests consisting of multiple usb-requests. A module option is there which disables the toggling of LEDs by the driver on certain triggers. Useful when being used in a "dark" environment.

Planes are separate memory buffers; each has its own mapping, backed by usually separate physical memory buffers. Many different uses for the multi-planar API are possible, examples include: - embedded devices requiring video components to be placed in physically separate buffers, e.g. for Samsung S3C/S5P SoC series' video codec, Y and interleaved Cb/Cr components reside in buffers in different memory banks; - applications may receive (or choose to store) video data of one video buffer in separate memory buffers; such data would have to be temporarily copied together into one buffer before passing it to a V4L2 device; - applications or drivers may want to pass metadata related to a buffer and it may not be possible to place it in the same buffer, together with video data.

It acts as an intermediate layer between userspace applications and device drivers. It also provides low-level, modular memory management functions for drivers. Videobuf2 eases driver development, reduces drivers' code size and aids in proper and consistent implementation of V4L2 API in drivers. Videobuf2 memory management backend is fully modular. This allows custom memory management routines for devices and platforms with non-standard memory management requirements to be plugged in, without changing the high-level buffer management functions and API. The framework provides: - implementations of streaming I/O V4L2 ioctls and file operations - high-level video buffer, video queue and state management functions - video buffer memory allocation and management Signed-off-by: Pawel Osciak Signed-off-by: Marek Szyprowski Signed-off-by: Kyungmin Park CC: Pawel Osciak Reviewed-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/Kconfig | 3 + drivers/media/video/Makefile | 2 + drivers/media/video/videobuf2-core.c | 1405 ++++++++++++++++++++++++++++++++++ include/media/videobuf2-core.h | 371 +++++++++ 4 files changed, 1781 insertions(+) create mode 100644 drivers/media/video/videobuf2-core.c create mode 100644 include/media/videobuf2-core.h (limited to 'drivers/media') diff --git a/drivers/media/video/Kconfig b/drivers/media/video/Kconfig index aa021600e9d..a4a6aa703c2 100644 --- a/drivers/media/video/Kconfig +++ b/drivers/media/video/Kconfig @@ -44,6 +44,9 @@ config V4L2_MEM2MEM_DEV tristate depends on VIDEOBUF_GEN +config VIDEOBUF2_CORE + tristate + # # Multimedia Video device configuration # diff --git a/drivers/media/video/Makefile b/drivers/media/video/Makefile index a509d317e25..6a1feba8786 100644 --- a/drivers/media/video/Makefile +++ b/drivers/media/video/Makefile @@ -111,6 +111,8 @@ obj-$(CONFIG_VIDEOBUF_VMALLOC) += videobuf-vmalloc.o obj-$(CONFIG_VIDEOBUF_DVB) += videobuf-dvb.o obj-$(CONFIG_VIDEO_BTCX) += btcx-risc.o +obj-$(CONFIG_VIDEOBUF2_CORE) += videobuf2-core.o + obj-$(CONFIG_V4L2_MEM2MEM_DEV) += v4l2-mem2mem.o obj-$(CONFIG_VIDEO_M32R_AR_M64278) += arv.o diff --git a/drivers/media/video/videobuf2-core.c b/drivers/media/video/videobuf2-core.c new file mode 100644 index 00000000000..b856bd105d7 --- /dev/null +++ b/drivers/media/video/videobuf2-core.c @@ -0,0 +1,1405 @@ +/* + * videobuf2-core.c - V4L2 driver helper framework + * + * Copyright (C) 2010 Samsung Electronics + * + * Author: Pawel Osciak + * Marek Szyprowski + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation. + */ + +#include +#include +#include +#include +#include +#include +#include + +#include + +static int debug; +module_param(debug, int, 0644); + +#define dprintk(level, fmt, arg...) \ + do { \ + if (debug >= level) \ + printk(KERN_DEBUG "vb2: " fmt, ## arg); \ + } while (0) + +#define call_memop(q, plane, op, args...) \ + (((q)->mem_ops->op) ? \ + ((q)->mem_ops->op(args)) : 0) + +#define call_qop(q, op, args...) \ + (((q)->ops->op) ?

It uses MMAP memory type buffers and generic vb2 calls: req_bufs, qbuf and dqbuf. Video date is being copied from mmap buffers to userspace with standard copy_to_user() function. To add support for file io the driver needs to provide an additional callback - read_setup or write_setup. It should provide the default number of buffers used by emulator and flags. With these flags one can detemine the style of read() or write() emulation. By default 'streaming' style is used. With VB2_FILEIO_READ_ONCE flag one can select 'one shot' mode for read() emulator. With VB2_FILEIO_WRITE_IMMEDIATE flag one can select immediate conversion of write calls to qbuf for write() emulator, so the vb2 will not wait until each buffer is filled completely before queueing it to the driver.

Thus it is not possible to use the generic power off function of the chip when sending one of them to standby. The other path will stop working in that case. The sleep function now switches off functionality specific to the demod path. The global stuff is only switched off, when both paths are in sleep mode. The wakeup function always turns on the global functionality and then works specific to the path.

A discussion were done at: http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html But there's not a solution for it yet. So, move the driver to staging, while we don't have a final solution.

With the time, it got newer meanings. Also, due to a bug at the logic, the driver might incorrectly return T_STANDBY to userspace. So, instead of keeping the abuse, just use a boolean for storing such information. We can't remove T_STANDBY yet, as this is used on two other drivers. A latter patch will address its usage outside tuner-core.

The PLL LPF was set to just 22000 symbol rate. Basically, the module is a Sharp BS2F7HZ0194 (STV0299+IX2410) I have had problems implementing the PLL in a new driver and did not want to break the IX2410 out of the PLL. This applies to DW2102, DM1105, CX88 and OPERA1 drivers.

+ Introduction + Media devices increasingly handle multiple related functions. Many USB + cameras include microphones, video capture hardware can also output video, + or SoC camera interfaces also perform memory-to-memory operations similar to + video codecs. + Independent functions, even when implemented in the same hardware, can + be modelled as separate devices. A USB camera with a microphone will be + presented to userspace applications as V4L2 and ALSA capture devices. The + devices' relationships (when using a webcam, end-users shouldn't have to + manually select the associated USB microphone), while not made available + directly to applications by the drivers, can usually be retrieved from + sysfs. + With more and more advanced SoC devices being introduced, the current + approach will not scale. Device topologies are getting increasingly complex + and can't always be represented by a tree structure. Hardware blocks are + shared between different functions, creating dependencies between seemingly + unrelated devices. + Kernel abstraction APIs such as V4L2 and ALSA provide means for + applications to access hardware parameters. As newer hardware expose an + increasingly high number of those parameters, drivers need to guess what + applications really require based on limited information, thereby + implementing policies that belong to userspace. + The media controller API aims at solving those problems. +

In addition to enumerating and configuring subdevices, video camera drivers need a way to discover and modify at runtime how those subdevices are connected. This is done through new elements called entities, pads and links. An entity is a basic media hardware building block. It can correspond to a large variety of logical blocks such as physical hardware devices (CMOS sensor for instance), logical hardware devices (a building block in a System-on-Chip image processing pipeline), DMA channels or physical connectors. A pad is a connection endpoint through which an entity can interact with other entities. Data (not restricted to video) produced by an entity flows from the entity's output to one or more entity inputs. Pads should not be confused with physical pins at chip boundaries. A link is a point-to-point oriented connection between two pads, either on the same entity or on different entities. Data flows from a source pad to a sink pad. Links are stored in the source entity. To make backwards graph walk faster, a copy of all links is also stored in the sink entity. The copy is known as a backlink and is only used to help graph traversal. The entity API is made of three functions: - media_entity_init() initializes an entity. The caller must provide an array of pads as well as an estimated number of links. The links array is allocated dynamically and will be reallocated if it grows beyond the initial estimate. - media_entity_cleanup() frees resources allocated for an entity. It must be called during the cleanup phase after unregistering the entity and before freeing it. - media_entity_create_link() creates a link between two entities. An entry in the link array of each entity is allocated and stores pointers to source and sink pads. When a media device is unregistered, all its entities are unregistered automatically. The code is based on Hans Verkuil initial work.

Userspace applications should enumerate entities using the MEDIA_ENT_ID_FLAG_NEXT flag. When the flag is set in the entity ID, the MEDIA_IOC_ENUM_ENTITIES will return the next entity with an ID bigger than the requested one. Only forward links that originate at one of the entity's source pads are returned during the enumeration process.

The pipeline API helps drivers manage that information. When starting streaming, drivers call media_entity_pipeline_start(). The function marks all entities connected to the given entity through enabled links, either directly or indirectly, as streaming. Similarly, when stopping the stream, drivers call media_entity_pipeline_stop(). The media_entity_pipeline_start() function takes a pointer to a media pipeline and stores it in every entity in the graph. Drivers should embed the media_pipeline structure in higher-level pipeline structures and can then access the pipeline through the media_entity structure. Link configuration will fail with -EBUSY by default if either end of the link is a streaming entity, unless the link is marked with the MEDIA_LNK_FL_DYNAMIC flag.

The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

The drivers usually reflect + the hardware model in software, and model the different hardware components + as software blocks called sub-devices. + + V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver + implements the media device API, they will automatically inherit from media + entities. Applications will be able to enumerate the sub-devices and discover + the hardware topology using the media entities, pads and links enumeration + API. + + In addition to make sub-devices discoverable, drivers can also choose + to make them directly configurable by applications. When both the sub-device + driver and the V4L2 device driver support this, sub-devices will feature a + character device node on which ioctls can be called to + + query, read and write sub-devices controls + subscribe and unsubscribe to events and retrieve them + negotiate image formats on individual pads + + + + Sub-device character device nodes, conventionally named + /dev/v4l-subdev*, use major number 81. + +
+ Controls + Most V4L2 controls are implemented by sub-device hardware. Drivers + usually merge all controls and expose them through video device nodes. + Applications can control all sub-devices through a single interface. + + Complex devices sometimes implement the same control in different + pieces of hardware. This situation is common in embedded platforms, where + both sensors and image processing hardware implement identical functions, + such as contrast adjustment, white balance or faulty pixels correction. As + the V4L2 controls API doesn't support several identical controls in a single + device, all but one of the identical controls are hidden. + + Applications can access those hidden controls through the sub-device + node with the V4L2 control API described in . The + ioctls behave identically as when issued on V4L2 device nodes, with the + exception that they deal only with controls implemented in the sub-device. + + + Depending on the driver, those controls might also be exposed through + one (or several) V4L2 device nodes. +
+ +
+ Events + V4L2 sub-devices can notify applications of events as described in + . The API behaves identically as when used on V4L2 + device nodes, with the exception that it only deals with events generated by + the sub-device. Depending on the driver, those events might also be reported + on one (or several) V4L2 device nodes. +
+ +
+ Pad-level Formats + + Pad-level formats are only applicable to very complex device that + need to expose low-level format configuration to user space. Generic V4L2 + applications do not need to use the API described in + this section. + + For the purpose of this section, the term + format means the combination of media bus data + format, frame width and frame height. + + Image formats are typically negotiated on video capture and output + devices using the cropping and scaling ioctls. + The driver is responsible for configuring every block in the video pipeline + according to the requested format at the pipeline input and/or + output. + + For complex devices, such as often found in embedded systems, + identical image sizes at the output of a pipeline can be achieved using + different hardware configurations. One such exemple is shown on + , where + image scaling can be performed on both the video sensor and the host image + processing hardware. + +
+ Image Format Negotation on Pipelines + + + + + + + + + High quality and high speed pipeline configuration + + +
+ + The sensor scaler is usually of less quality than the host scaler, but + scaling on the sensor is required to achieve higher frame rates. Depending + on the use case (quality vs. speed), the pipeline must be configured + differently. Applications need to configure the formats at every point in + the pipeline explicitly. + + Drivers that implement the media + API can expose pad-level image format configuration to applications. + When they do, applications can use the &VIDIOC-SUBDEV-G-FMT; and + &VIDIOC-SUBDEV-S-FMT; ioctls. to negotiate formats on a per-pad basis. + + Applications are responsible for configuring coherent parameters on + the whole pipeline and making sure that connected pads have compatible + formats. The pipeline is checked for formats mismatch at &VIDIOC-STREAMON; + time, and an &EPIPE; is then returned if the configuration is + invalid. + + Pad-level image format configuration support can be tested by calling + the &VIDIOC-SUBDEV-G-FMT; ioctl on pad 0. If the driver returns an &EINVAL; + pad-level format configuration is not supported by the sub-device. + +
+ Format Negotiation + + Acceptable formats on pads can (and usually do) depend on a number + of external parameters, such as formats on other pads, active links, or + even controls. Finding a combination of formats on all pads in a video + pipeline, acceptable to both application and driver, can't rely on formats + enumeration only. A format negotiation mechanism is required. + + Central to the format negotiation mechanism are the get/set format + operations. When called with the which argument + set to V4L2_SUBDEV_FORMAT_TRY, the + &VIDIOC-SUBDEV-G-FMT; and &VIDIOC-SUBDEV-S-FMT; ioctls operate on a set of + formats parameters that are not connected to the hardware configuration. + Modifying those 'try' formats leaves the device state untouched (this + applies to both the software state stored in the driver and the hardware + state stored in the device itself). + + While not kept as part of the device state, try formats are stored + in the sub-device file handles. A &VIDIOC-SUBDEV-G-FMT; call will return + the last try format set on the same sub-device file + handle. Several applications querying the same sub-device at + the same time will thus not interact with each other. + + To find out whether a particular format is supported by the device, + applications use the &VIDIOC-SUBDEV-S-FMT; ioctl. Drivers verify and, if + needed, change the requested format based on + device requirements and return the possibly modified value. Applications + can then choose to try a different format or accept the returned value and + continue. + + Formats returned by the driver during a negotiation iteration are + guaranteed to be supported by the device. In particular, drivers guarantee + that a returned format will not be further changed if passed to an + &VIDIOC-SUBDEV-S-FMT; call as-is (as long as external parameters, such as + formats on other pads or links' configuration are not changed). + + Drivers automatically propagate formats inside sub-devices. When a + try or active format is set on a pad, corresponding formats on other pads + of the same sub-device can be modified by the driver. Drivers are free to + modify formats as required by the device. However, they should comply with + the following rules when possible: + + Formats should be propagated from sink pads to source pads. + Modifying a format on a source pad should not modify the format on any + sink pad. + Sub-devices that scale frames using variable scaling factors + should reset the scale factors to default values when sink pads formats + are modified. If the 1:1 scaling ratio is supported, this means that + source pads formats should be reset to the sink pads formats. + + + + Formats are not propagated across links, as that would involve + propagating them from one sub-device file handle to another. Applications + must then take care to configure both ends of every link explicitly with + compatible formats. Identical formats on the two ends of a link are + guaranteed to be compatible. Drivers are free to accept different formats + matching device requirements as being compatible. + + + shows a sample configuration sequence for the pipeline described in + (table + columns list entity names and pad numbers). + + + Sample Pipeline Configuration + + + + + + + + + + + Sensor/0 + Frontend/0 + Frontend/1 + Scaler/0 + Scaler/1 + + + + + Initial state + 2048x1536 + - + - + - + - + + + Configure frontend input + 2048x1536 + 2048x1536 + 2046x1534 + - + - + + + Configure scaler input + 2048x1536 + 2048x1536 + 2046x1534 + 2046x1534 + 2046x1534 + + + Configure scaler output + 2048x1536 + 2048x1536 + 2046x1534 + 2046x1534 + 1280x960 + + + +

I've encountered a couple of problems with the current af9015 driver as supplied with the 2.6.37 kernel, that the attached patch appears to fix. (I've generated this patch against the current v4l-dvb git). Some key-presses are lost. A key-press is only generated upon 'valid' data (buf[14] == (u8) ~buf[15]), but the buffer is wiped before this check. Sometimes the 15th byte has not been set at the time of read, so the data isn't valid & ignored. On the next poll the 15th byte has been set, but the rest of the data was wiped previously, so the data is still invalid & the key is lost. Weird repeat error, where an old key press is sometimes repeated in error. ie. button sequence '1 (pause) 2 (pause) 3 (pause) 4' generates output like '1 (pause) 2 (pause) 23 (pause) 4'. The current driver zeroes the data for the key pushed, but sometimes this data is already zero but with other bytes set suggesting a repeat code. This results in the last key being incorrectly repeated. This patch attempts to reduce the risk of a missed key-press & also stop the random repeat of an old key-press when a new key is pressed.

It makes a lot of sense. Changing it is not a problem :) How about the updated patch below? If the memory allocation to 'state' succeeds but we jump to the 'error' label before 'state' is assigned to fe->tuner_priv, then the call to 'zl10036_release(fe)' at the 'error:' label will not free 'state', but only what was previously assigned to 'tuner_priv', thus leaking the memory allocated to 'state'. This patch fixes the leak and also does not jump to 'error:' before mem has been allocated but instead just returns. Also some small style cleanups.

Apparently, for key up events to be generated, a certain GPIO pin must be set. Currently it's set in saa7134_input_init1(), but that function is not called on device resume. I suggest that code be moved to __saa7134_ir_start(), which is called both on init and resume.

Most implement some use count mechanism, but if they use v4l2_fh, then you can also just check if this is the only filehandle for the device node. A simple helper function can do this.

But no such support was available for struct v4l2_device. This made it hard to determine when a USB driver can release the device if it has multiple device nodes. With one device node it is easy of course, since when the device node is released, the whole device can be released. This patch adds refcounting to v4l2_device. When registering device nodes the v4l2_device refcount will be increased, when releasing device nodes it will be decreased. The (optional) release function will be called when the last device node was released.

VIDEO_SAA7134_RC (which determines if saa7134-input.o is built) depends on RC_CORE and VIDEO_SAA7134. If VIDEO_SAA7134 is compiled as 'y' but RC_CORE is compiled as 'm' VIDEO_SAA7134_RC can still be set to 'y' which causes undefined symbols that it needs from RC_CORE. The simplest solution is to not allow VIDEO_SAA7134_RC be enabled if RC_CORE compiled as a module (m) and VIDEO_SA7134 is compiled into the kernel (y).

Garcia de Soria" Date: Wed, 16 Mar 2011 17:14:52 -0300 Subject: [media] rc: New rc-based ite-cir driver for several ITE CIRs This is a second version of an rc-core based driver for the ITE Tech IT8712F CIR and now for a pair of other variants of the IT8512 CIR too. This driver should replace the lirc_it87 and lirc_ite8709 currently living in the LIRC staging directory. The driver should support the ITE8704, ITE8713, ITE8708 and ITE8709 (this last one yet untested) PNP ID's. The code doesn'te reuse code from the pre-existing LIRC drivers, but has been written from scratch using the nuvoton.cir driver as a skeleton. This new driver shouldn't exhibit timing problems when running under load (or with interrupts disabled for relatively long times). It works OOTB with the RC6 MCE remote bundled with the ASUS EEEBox. TX support is implemented, but I'm unable to test it since my hardware lacks TX capability. Signed-off-by: Juan J.

However, both tables are miss-named. Also, the old rc-hauppauge-new is broken, as it mixes three different controllers as if they were just one. This patch solves half of the problem by renaming the correct keycode table as just rc-hauppauge. This table contains the codes for the four different types of remote controllers found on Hauppauge cards, properly mapped with their different addresses. create mode 100644 drivers/media/rc/keymaps/rc-hauppauge.c delete mode 100644 drivers/media/rc/keymaps/rc-rc5-hauppauge-new.c [Jarod: fix up RC_MAP_HAUPPAUGE defines] Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jarod Wilson --- drivers/media/dvb/siano/sms-cards.c | 2 +- drivers/media/rc/keymaps/Makefile | 2 +- drivers/media/rc/keymaps/rc-hauppauge.c | 241 ++++++++++++++++++++++++ drivers/media/rc/keymaps/rc-rc5-hauppauge-new.c | 235 ----------------------- drivers/media/rc/mceusb.c | 2 +- drivers/media/video/cx23885/cx23885-input.c | 2 +- drivers/media/video/em28xx/em28xx-cards.c | 4 +- include/media/rc-map.h | 4 +- 8 files changed, 249 insertions(+), 243 deletions(-) create mode 100644 drivers/media/rc/keymaps/rc-hauppauge.c delete mode 100644 drivers/media/rc/keymaps/rc-rc5-hauppauge-new.c (limited to 'drivers/media') diff --git a/drivers/media/dvb/siano/sms-cards.c b/drivers/media/dvb/siano/sms-cards.c index 25b43e587fa..af121db88ea 100644 --- a/drivers/media/dvb/siano/sms-cards.c +++ b/drivers/media/dvb/siano/sms-cards.c @@ -64,7 +64,7 @@ static struct sms_board sms_boards[] = { .type = SMS_NOVA_B0, .fw[DEVICE_MODE_ISDBT_BDA] = "sms1xxx-hcw-55xxx-isdbt-02.fw", .fw[DEVICE_MODE_DVBT_BDA] = "sms1xxx-hcw-55xxx-dvbt-02.fw", -

Also, some key maps are wrong. With the conversion to the new rc-core, it is likely that most of the devices won't be working properly, as the i2c driver and the raw decoders are now providing 16 bits for the remote, instead of just 8. delete mode 100644 drivers/media/rc/keymaps/rc-hauppauge-new.c Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jarod Wilson --- drivers/media/dvb/ttpci/budget-ci.c | 15 +++- drivers/media/rc/keymaps/Makefile | 1 - drivers/media/rc/keymaps/rc-hauppauge-new.c | 100 ------------------------- drivers/media/video/cx18/cx18-i2c.c | 2 +- drivers/media/video/cx88/cx88-input.c | 4 +- drivers/media/video/em28xx/em28xx-cards.c | 6 +- drivers/media/video/hdpvr/hdpvr-i2c.c | 2 +- drivers/media/video/ir-kbd-i2c.c | 4 +- drivers/media/video/ivtv/ivtv-i2c.c | 2 +- drivers/media/video/pvrusb2/pvrusb2-i2c-core.c | 4 +- drivers/media/video/saa7134/saa7134-input.c | 2 +- 11 files changed, 25 insertions(+), 117 deletions(-) delete mode 100644 drivers/media/rc/keymaps/rc-hauppauge-new.c (limited to 'drivers/media') diff --git a/drivers/media/dvb/ttpci/budget-ci.c b/drivers/media/dvb/ttpci/budget-ci.c index b82756db5bd..1d79ada864d 100644 --- a/drivers/media/dvb/ttpci/budget-ci.c +++ b/drivers/media/dvb/ttpci/budget-ci.c @@ -26,7 +26,7 @@ * Or, point your browser to http://www.gnu.org/copyleft/gpl.html * * - * the project's page is at http://www.linuxtv.org/ + * the project's page is at http://www.linuxtv.org/ */ #include @@ -102,6 +102,7 @@ struct budget_ci_ir { int rc5_device;

It also contains some keycodes not found there. As the Hauppauge Black is now part of the hauppauge keymap, just remove it. Also, remove the modprobe hacks to select between the Gray and the Black versions of the remote controller as: - Both are supported by default by the keymap; - If the user just wants one keyboard supported, it is just a matter of changing the keymap via the userspace tool (ir-keytable), removing the keys that he doesn't desire. As ir-keytable auto-loads the keys via udev, this is better than obscure modprobe parameters.

This change makes the NEC decoder warn if the command/not_command checksum fails, but then passes along a full 32-bit scancode for keymap lookup. This change should make no difference for existing keymaps, since they simply won't have 32-bit scancodes, but allows for a 32-bit keymap. At the moment, that'll have to be uploaded by the user, but I've got Apple and TiVo remote keymaps forthcoming. In the long run (2.6.40, hopefully), we should probably just always use all 32 bits for all NEC keymaps, but this should get us by for 2.6.39. (Note that a few of the TiVo keys actuallly *do* pass the command checksum, so for now, the keymap for this remote will have to be a mix of 24-bit and 32-bit scancodes, but so be it).
