Separate JPEG encoder and decoder video devices are created due to different streaming behaviour and different supported pixel formats. The hardware can not change subsampling on the fly, but encode and decode 4:2:2 subsampled JPEG images from and into this format. The CODA7541 JPEG decoder uses the bitstream buffer and thus can run without new buffers queued if there is a buffer in the bitstream. Since there is no standard way to store the colorspace used in JPEGs, and to make v4l2-compliance happy, the JPEG format always reports V4L2_COLORSPACE_JPEG.

This patch also renames struct coda_timestamp to struct coda_buffer_meta to make clear that it contains more than only the buffer timestamp.

It's possible for it to clear the hw_lock, making other instances trigger a BUG() on hw_lock checks. Since it's not fatal to clear the hw_lock to zero twice, just WARN in those cases for now. We should not explode, as firmware will return errors as needed for other instances after it's reloaded, or they will time out. A clean fix should involve killing other instances when watchdog kicks in, but requires a major redesign of locking in the driver.

Sometimes, we error out during dpb flush because of lack of src buffers. Since we have not started decoding new resolution yet, it is simpler to push zero-size buffer until we flush out all dpbs. This is already been done while handling EOS command, and this patch extends the same logic to resolution change as well.

Until anyone who still has this old hardware steps up an does the conversion, fix it by not calling the symbol_request calls if the driver is compiled in without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE). Due to the IR related pointers beeing NULL by default, IR support will then be disabled. The downside of this solution is, that it will no longer be possible to compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in. Please note that this patch has NOT been tested with all possible cases. I don't have the hardware and could only verify that it fixes the reported bug.

And since this affects blackbird, alsa, core, dvb, vbi and video the changes are all over. What made this more difficult was the peculiar way the risc program was setup. The driver allowed for running out of buffers in which case the DMA would stop and restart when the next buffer was queued. There was also a complicated timeout system for when buffers weren't filled. This was replaced by a much simpler scheme where there is always one buffer around and the DMA will just cycle that buffer until a new buffer is queued. In that case the previous buffer will be chained to the new buffer. An interrupt is generated at the start of the new buffer telling the driver that the previous buffer can be passed on to userspace. Much simpler and more robust.

Especially complicated command like CX2341X_ENC_STOP_CAPTURE takes much more time than 10 ms. Increase the timeout to 1 second, just as ivtv does (the cx88-blackbird has the same IP core for MPEG compression as ivtv). This solves a nasty issue where STOP_CAPTURE would timeout and the mailbox is left in a busy state, making it impossible to start streaming a second time without reloading the driver first.

If we flip the "if (!lock) {" test to "if (lock) return;" then we can remove an indent level from the rest of the function. We can add two returns in the "if (state->srate >= 10000000) {" condition and move the else statement back an additional indent level. There is another "if (!lock) {" check which can be removed since we have already checked "lock" and know it is zero at this point. This second check on "lock" is also a problem because it sets off a static checker warning. I have reviewed this code for some time to see if something else was intended, but have concluded that it was simply an oversight and should be removed. Removing this duplicative check gains us an third indent level.

However, unlike the former bug, this one is much less harmful, because it only results in the kernel failing to write the .type field back to the user, but in fact this is likely unneeded, because the kernel will hardly want to change that field. Therefore this bug is more of a theoretical nature.

Also, the printk's data are not too coherent: - there are duplicated driver name at the print format; - function name format string differs from function to function; - long strings broken into multiple lines; - some printks just produce ugly reports, being almost useless as-is. Do a cleanup on that. Still, there are much to be done in order to do a better printk job on this driver, but, at least it will now be a way less verbose, if debug printks are disabled, and some logs might actually be useful.

This could potentially cause an OOPS. So, simplify the logic a little bit and return an error if frontend fails before trying to setup VB2 queue.

Its internal demod is similar with M88DS3103 except some registers definition. The main different part of this internal demod from others is its clock/pll generation IP block sitting inside the tuner die. So clock/pll functions should be configed through its tuner i2c bus, NOT its demod i2c bus.

Also note that readl/writel already do endian conversion, so there is no need to do it again. saa7164_bus_set/get were a bit tricky: you have to make sure the msg endian conversion is done at the right time, and that the code isn't using fields that are still little endian instead of cpu-endianness. The approach chosen is to convert just before writing to the ring buffer and to convert it back right after reading from the ring buffer.

However, that plan was a mistake as driver code differences are so small between different standards. Due to that rename this file and implement all the needed functionality to that file.

The omap2 camera driver and the tcm825x sensor driver have been deprecated for a year and are now being removed. They are unmaintained and they use an internal API that has long since been superseded by a much better API. Worse, that internal API has been abused by out-of-kernel trees (i.MX6). In addition, Sakari stated that these drivers have never been in a usable state in the mainline kernel due to missing platform data.

Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.

As Jim reported: drivers/built-in.o: In function `technisat_usb2_set_voltage': technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio' make: *** [vmlinux] Error 1 That happens because, on his configuration, the configuration is: CONFIG_DVB_USB=y CONFIG_DVB_STV090x=m Luis proposed ar way to fix, but that would just force the STV090x to be selected, even if one wants to use a device with a different frontend. Instead, let's do the right thing: move set_gpio to the configuration structure and fill it during dvb_attach(). This way, the driver can still call it, and dvb_attach() will load stv090x module only if the device really needs it.

The sequence is: - The polaris powered off but with the powerdown controller (PDC) block still powered. - Press power key on remote, IR block receives the key. - Kernel starts, IR code is in IMG_IR_DATA_x but neither IMG_IR_RXDVAL or IMG_IR_RXDVALD2 are set. - Wait any amount of time. - Press any key. - IMG_IR_RXDVAL or IMG_IR_RXDVALD2 is set but IMG_IR_DATA_x is unchanged since the powerup key data was never read. This is worked around by always reading the IMG_IR_DATA_x in img_ir_set_decoder(), rather than only when the IMG_IR_RXDVAL or IMG_IR_RXDVALD2 bit is set.

When the protocol is changed, the end timer is deleted synchronously with del_timer_sync(), however this takes place while holding the main spin lock, and the timer handler also needs to acquire the spin lock. This opens the possibility of a deadlock on an SMP system if the protocol is changed just as the repeat timer is expiring. One CPU could end up in img_ir_set_decoder() holding the lock and waiting for the end timer to complete, while the other CPU is stuck in the timer handler spinning on the lock held by the first CPU. Lockdep also spots a possible lock inversion in the same code, since img_ir_set_decoder() acquires the img-ir lock before the timer lock, but the timer handler will try and acquire them the other way around: ========================================================= [ INFO: possible irq lock inversion dependency detected ] 3.18.0-rc5+ #957 Not tainted --------------------------------------------------------- swapper/0/0 just changed the state of lock: (((&hw->end_timer))){+.-...}, at: [<4006ae5c>] _call_timer_fn+0x0/0xfc but this lock was taken by another, HARDIRQ-safe lock in the past: (&(&priv->lock)->rlock#2){-.....} and interrupts could create inverse lock ordering between them. other info that might help us debug this: Possible interrupt unsafe locking scenario: CPU0 CPU1 ---- ---- lock(((&hw->end_timer))); local_irq_disable(); lock(&(&priv->lock)->rlock#2); lock(((&hw->end_timer))); lock(&(&priv->lock)->rlock#2); *** DEADLOCK *** This is fixed by releasing the main spin lock while performing the del_timer_sync() call.
