| * | | [media] dvb-frontend: Replace timeval with ktime_tTina Ruchandani2015-06-103-37/+19Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct timeval uses a 32-bit seconds representation which will overflow in the year 2038 and beyond. This patch replaces the usage of struct timeval with ktime_t which is a 64-bit timestamp and is year 2038 safe. This patch is part of a larger attempt to remove all instances of 32-bit timekeeping variables (timeval, timespec, time_t) which are not year 2038 safe, from the kernel.

| * | | [media] b2c2: Add option to skip the first 6 pid filtersJemma Denson2015-06-103-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flexcop bridge chip has two banks of hardware pid filters - an initial 6, and on some chip revisions an additional bank of 32. A bug is present on the initial 6 - when changing transponders one of two PAT packets from the old transponder would be included in the initial packets from the new transponder. This usually transpired with userspace programs complaining about services missing, because they are seeing a PAT that they would not be expecting. Running in full TS mode does not exhibit this problem, neither does using just the additional 32. This patch adds in an option to not use the inital 6 and solely use just the additional 32, and enables this option for the SkystarS2 card. Other cards can be added as required if they also have this bug. Signed-off-by: Jemma Denson <jdenson@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
| * | | [media] ddbridge: Do not free_irq() if request_irq() failedTakeshi Yoshimura2015-06-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My static checker detected that free_irq() is called even after request_irq() failed in ddb_probe(). In this case, the kernel may try to free dev->pdev->irq although the IRQ is not assigned. This event rarely occurs, but always introduces a warning if it happens. "goto fail1" always results in disabling enabled MSI and releasing a requested IRQ. It seems like the former handling is necessary. So I added a conditional branch before the free_irq() (stat == 0 means request_irq() succeeds).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the colors for the Y16 and Y16_BE pixelformats are in the range 0x0000-0xff00. So pure white (0xffff) is never created. Improve this by making white really white. For other colors the lsb remains 0 so vivid can be used to detect endian problems.

So pass the IRQF_ONESHOT flag in this case. The semantic patch that makes this change is available in scripts/coccinelle/misc/irqf_oneshot.cocci.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has been on my TODO list for some time now: the control that enables the video loopback was part of the controls of the video output device instead of the video capture device. In practice this was quite annoying since you expect it at the capture side since that's where you want to make the decision whether to use the TPG or looped video. This patch moves the control from the output to the capture side. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

If the pclk-sample property is defined for the BT656 bus, it is still marked as a parallel bus. Fix this by parsing the pclk after the bus_type is selected. Only when hsync or vsync properties are specified, the bus_type should be set to V4L2_MBUS_PARALLEL.

This patch takes a different approach: four different functions are created, one for each PRINTSTR version. In order to avoid the 'the frame size of 1308 bytes is larger than 1024 bytes' warning I had to mark those functions with 'noinline'. For whatever reason gcc seems to inline this aggressively and it is doing weird things with the stack. I tried to read the assembly code, but I couldn't see what exactly it was doing on the stack.
