media: vimc: cap: check v4l2_fill_pixfmt return value

2019-07-26T07:14:11+00:00

[ Upstream commit 77ae46e11df5c96bb4582633851f838f5d954df4 ] v4l2_fill_pixfmt() returns -EINVAL if the pixelformat used as parameter is invalid or if the user is trying to use a multiplanar format with the singleplanar API. Currently, the vimc_cap_try_fmt_vid_cap() returns such value, but vimc_cap_s_fmt_vid_cap() is ignoring it. Fix that and returns an error value if vimc_cap_try_fmt_vid_cap() has failed.

media: vimc: zero the media_device on probe

2019-05-31T13:46:33+00:00

[ Upstream commit f74267b51cb36321f777807b2e04ca02167ecc08 ] The media_device is part of a static global vimc_device struct. The media framework expects this to be zeroed before it is used, however, since this is a global this is not the case if vimc is unbound and then bound again. So call memset to ensure any left-over values are cleared. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin

media: vimc: stream: fix thread state before sleep

2019-05-31T13:46:33+00:00

[ Upstream commit 2978a505aaa981b279ef359f74ba93d25098e0a0 ] The state TASK_UNINTERRUPTIBLE should be set just before schedule_timeout() call, so it knows the sleep mode it should enter. There is no point in setting TASK_UNINTERRUPTIBLE at the initialization of the thread as schedule_timeout() will set the state back to TASK_RUNNING. This fixes a warning in __might_sleep() call, as it's expecting the task to be in TASK_RUNNING state just before changing the state to a sleeping state.

media: vimc: Add vimc-streamer for stream control

2019-03-23T19:10:12+00:00

commit adc589d2a20808fb99d46a78175cd023f2040338 upstream. Add a linear pipeline logic for the stream control. It's created by walking backwards on the entity graph. When the stream starts it will simply loop through the pipeline calling the respective process_frame function of each entity.

Merge tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2018-08-18T18:04:51+00:00

Pull char/misc driver updates from Greg KH: "Here is the bit set of char/misc drivers for 4.19-rc1 There is a lot here, much more than normal, seems like everyone is writing new driver subsystems these days... Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (255 commits) android: binder: Rate-limit debug and userspace triggered err msgs fsi: sbefifo: Bump max command length fsi: scom: Fix NULL dereference misc: mic: SCIF Fix scif_get_new_port() error handling misc: cxl: changed asterisk position genwqe: card_base: Use true and false for boolean values misc: eeprom: assignment outside the if statement uio: potential double frees if __uio_register_device() fails eeprom: idt_89hpesx: clean up an error pointer vs NULL inconsistency misc: ti-st: Fix memory leak in the error path of probe() android: binder: Show extra_buffers_size in trace firmware: vpd: Fix section enabled flag on vpd_section_destroy platform: goldfish: Retire pdev_bus goldfish: Use dedicated macros instead of manual bit shifting goldfish: Add missing includes to goldfish.h mux: adgs1408: new driver for Analog Devices ADGS1408/1409 mux dt-bindings: mux: add adi,adgs1408 Drivers: hv: vmbus: Cleanup synic memory free path Drivers: hv: vmbus: Remove use of slow_virt_to_phys() Drivers: hv: vmbus: Reset the channel callback in vmbus_onoffer_rescind() ...

media: vimc: Remove redundant free

Commit 4a29b7090749 ("[media] vimc: Subdevices as modules") removes vimc allocation from vimc_probe(), so corresponding deallocation on the error path tries to free static memory.

media: v4l2-tpg*.h: move headers to include/media/tpg and merge them

2017-12-18T17:28:35+00:00

The v4l2-tpg*.h headers are meant to be used only internally by vivid and vimc. There's no sense keeping them together with the V4L2 kAPI headers. Also, one header includes the other as they're meant to be used together. So, merge them. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
