My earlier patch missed two functions, these must be __maybe_unused as well: drivers/media/pci/intel/ipu3/ipu3-cio2.c:1867:12: error: 'cio2_runtime_resume' defined but not used [-Werror=unused-function] drivers/media/pci/intel/ipu3/ipu3-cio2.c:1849:12: error: 'cio2_runtime_suspend' defined but not used [-Werror=unused-function] Fixes: 2086dd35 ("media: intel-ipu3: cio2: mark PM functions as __maybe_unused") Signed-off-by:

This directory contains the videobuf2 framework, so name the directory accordingly. The name 'videobuf' typically refers to the old and deprecated videobuf version 1 framework so that was confusing. Signed-off-by:

The cobalt sound driver has a dependency on ALSA, but not on the PCM helper code, so this can lead to an extremely rare link error in randconfig builds: ERROR: "snd_pcm_period_elapsed" [drivers/media/pci/cobalt/cobalt.ko] undefined!

Mention the maximum voltages of the CEC and HPD lines. Since in the example these lines are connected to a Raspberry Pi and the Rpi GPIO lines are 3.3V it is a good idea to warn against directly connecting the HPD to the Raspberry Pi's GPIO line. Signed-off-by:

The rc5 protocol does not have a leading pulse or space, but we encode the first bit using a single leading pulse. For other protocols, the leading pulse or space does not represent any bit. So, don't remove the first bit if a leading pulse is present. Cc: Antti Seppälä <a.seppala@gmail.com> Signed-off-by:

The ioctl change the current mode or return the current mode; they do not tell you which modes are possible (use the lirc features ioctl for that). Signed-off-by:

Sean Young authored
Since commit 9b619258 ("media: lirc: implement scancode sending"), and commit de142c32 ("media: lirc: implement reading scancode") the lirc features ioctl for raw IR devices advertises two modes for sending and receiving. The lirc daemon now fails to detect a raw IR device, both for transmit and receive. To fix this, do not advertise the scancode mode in the lirc features for raw IR devices (however do keep it for scancode devices). The mode can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

Since commit a60d64b1 ("media: lirc: lirc interface should not be a raw decoder"), there is no lirc_dev module any more. On Ubuntu 16.10, the /etc/init.d/lirc startup script attempts to load the lirc_dev module. Since this module does not exist any more, this script fails. Add an alias so the correct module is loaded.

The current error exit path if ir_raw_encode_scancode fails is via the label out_kfree which kfree's an uninitialized pointer txbuf. Fix this by exiting via a new exit path that does not kfree txbuf. Also exit via this new exit path for a failed allocation of txbuf to avoid a redundant kfree on a NULL pointer (to save a bunch of CPU cycles).

When dmabuf is used for BLOB type frame, the frame buffers allocated by gralloc will hold more pages than the valid frame data due to height alignment. In this case, the page numbers in sg list could exceed the FBPT upper limit value - max_lops(8)*1024 to cause crash. Limit the LOP access to the valid data length to avoid FBPT sub-entries overflow.

The driver apparently assumes that the device uses the same page size as the CPU, but also assumes that this is 4096 bytes. On architectures with a larger page size like 65536 bytes, we get a warning about an integer overflow: drivers/media/pci/intel/ipu3/ipu3-cio2.c: In function 'cio2_fbpt_entry_init_dummy': arch/arm64/include/asm/page-def.h:28:20: error: large integer implicitly truncated to unsigned type [-Werror=overflow] #define PAGE_SIZE (_AC(1, UL) << PAGE_SHIFT) ^ drivers/media/pci/intel/ipu3/ipu3-cio2.h:404:26: note: in expansion of macro 'PAGE_SIZE' #define CIO2_PAGE_SIZE PAGE_SIZE ^~~~~~~~~ drivers/media/pci/intel/ipu3/ipu3-cio2.c:172:3: note: in expansion of macro 'CIO2_PAGE_SIZE' CIO2_PAGE_SIZE / sizeof(u32) * CIO2_MAX_LOPS; Obviously this won't work, but the driver is also unlikely to ever be used on such an architecture, so the easiest workaround is to define the CIO2_PAGE_SIZE macro to the size that the hardware actually uses.

Some UVC video cameras contain metadata in their payload headers. This patch extracts that data, adding more clock synchronisation information, on both bulk and isochronous endpoints and makes it available to the user space on a separate video node, using the V4L2_CAP_META_CAPTURE capability and the V4L2_BUF_TYPE_META_CAPTURE buffer queue type. By default, only the V4L2_META_FMT_UVC pixel format is available from those nodes. However, cameras can be added to the device ID table to additionally specify their own metadata format, in which case that format will also become available from the metadata node. [Use put_unaligned instead of __put_unaligned_cpu64] [Use put_unaligned for the sof field as well] Signed-off-by:
