The location in which last_buffer_queued is set is moved to fill_v4l2_buffer(). So, __vb2_perform_fileio() can use vb2_core_dqbuf() instead of vb2_internal_dqbuf(). Signed-off-by:

Move timestamp from struct vb2_v4l2_buffer to struct vb2_buffer for common use, and change its type to u64 in order to handling y2038 problem. This patch also includes all device drivers' changes related to this restructuring. Signed-off-by:

The timestamp of a v4l2_buffer was advertised as being CLOCK_MONOTONIC, but instead a timestamp from a header field was used. This is inconsistent and not what applications expect. Use v4l2_get_timestamp to properly set the timestamp. Signed-off-by:

During the Seoul media workshop we decided to relax the VIDIOC_CREATE_BUFS specification so it would no longer require drivers to validate the format field since almost no driver did that anyway. Instead drivers use the buffer size(s) based on the format type and the corresponding format fields and will ignore any other fields. If the size cannot be used an error is returned, otherwise the size is used as-is. Signed-off-by:
-
Hans Verkuil authored
The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by:

The VID_A_GPCNT register is for video, not vbi. Read from the right register and don't write to the video register. Based upon Devin's initial patch made for an older kernel which I cleaned up and rebased. Thanks to Kernel Labs for that work. Signed-off-by:

This is necessary since the *_std_setup functions rely on a valid state->std field. Also fix the cx23888_std_setup() to test for 60Hz instead of NTSC, just like cx25840_std_setup() does. Signed-off-by:

For those two devices the code wrote to addresses 0x115/6, but on those devices those addresses have nothing to do with power controls. So clearly this never worked. Rather than writing to bogus addresses, just do nothing for the cx2388x and cx231xx. Signed-off-by:

The cx23888 reports a slightly different Vsrc value than the other chip variants do. Relax the check by 1, otherwise cx25840_set_fmt() would fail for the cx23888. Signed-off-by:
-
Hans Verkuil authored
The cx23888 also moves the following registers around: !cx23888 cx23888 -------- ------- 0x418, 0x41c 0x434, 0x438 0x420 0x418 (expect for bit 29 which has a different meaning) 0x478 0x454 Also drop the set_input code where the scaler is changed: this does not belong here, changing the input should not change the scaler. And that's besides the fact that that code is plain wrong. After this change the cx23888 behaves much better. In particular, calling set_input no longer changes the saturation to 0, causing a grayscale image. Signed-off-by:

The cx23888 has the VBI registers at different addresses compared to the other variants. In most cases it is a fixed offset, but not always. Update the code so the right registers are written for the cx23888. Signed-off-by:

These two drivers reported the pixel aspect ratio the wrong way around. This caused qv4l2 to scale the image incorrectly. Signed-off-by:
-
Hans Verkuil authored
The pixelaspect ratio was set incorrectly for 60Hz formats. And since cropcap wasn't implemented at all for the -417 (compressed video) the pixelaspect was unknown for compressed video. Signed-off-by:

While testing the cx23885 driver with various TV standards I found a number of bugs: 1) norm_maxw() returned 768 instead of 720 for PAL formats. This should always be 720, so drop this inline function and just always use 720. 2) cropcap() was missing, so the pixelaspect was never known and qv4l2 would scale the image incorrectly. Add cropcap support. 3) cx23885_set_tvnorm() should just return 0 if the same standard was set again. If another standard is set, then reset the width/height and call set_fmt for the subdevs. Signed-off-by:

'struct timeval tv' and 'struct timeval now' is used to calculate the elapsed time. 'LIRC_SFH506_DELAY' is a delay t_phl in usecs. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the lirc_parallel.c file of media: lirc driver to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub is used to subtract two ktime variables. ktime_to_us() is used to convert ktime to microsecond. New ktime_t variable timeout, is added in lirc_off(),to improve clarity. Introduced a new ktime_t variable in lirc_lirc_irq_handler() function, to avoid the use of signal variable for storing seconds in the first part of this function as later it uses a time unit that is defined by the global "timer" variable. This makes it more clear. ktime_set() is used to set a value in seconds to a value in nanosecond so that ktime_compare() can be used appropriately. ktime_compare() is used to compare two ktime values. ktime_add_ns() is used to increment a ktime value by 1 sec. One comment is also shifted a line up, as it was creating a 80 character warning. Build tested it. Also tested it with sparse. Signed-off-by:

'struct timeval presstime' and 'struct timeval tv' is used to calculate the time since the last button press. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the media: lirc driver to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub() are used to subtract two ktime variables. 'ms' is only used to check how much time has passed by comparing to 250. So instead of using expensive ktime_to_ms() call, it has been changed to hold nanoseconds by using ktime_to_ns(). Build tested it. Tested with sparse too. Signed-off-by:

'struct timeval tv' is used to get current time. 'static struct timeval lasttv' is used to get last interrupt time. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the lirc_serial.c file of media: lirc to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub is used to subtract two ktime variables. The check to test time going backwards is also removed. Intialization to static variable is also removed. ktime_to_us() is used to convert ktime_t to microsecond value. deltv is changed to delkt, a ktime_t type varibale from long to assign the ktime_sub value directly. ktime_compare is used to compare delkt with 15 seconds, which is changed to a nanosecond value by using ktime_set(). Build tested it. Signed-off-by:

Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way), before any state associated with the IRQ is freed. Patch was generated using the following semantic patch: // <smpl> @@ expression irq; @@ -synchronize_irq(irq); free_irq(irq, ...); // </smpl> Signed-off-by:
