2018-05-28media: v4l2-core: push taking ioctl mutex down to ioctl handlerHans Verkuil2-21/+0
The ioctl serialization mutex (vdev->lock or q->lock for vb2 queues) was taken at the highest level in v4l2-dev.c. This prevents more fine-grained locking since at that level we cannot examine the ioctl arguments, we can only do that after video_usercopy is called. So push the locking down to __video_do_ioctl() and subdev_do_ioctl_lock(). This also allows us to make a few functions in v4l2-ioctl.c static and video_usercopy() is no longer exported. The locking scheme is not changed by this patch, just pushed down. Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-05-28media: v4l2-ioctl: delete unused v4l2_disable_ioctl_lockingHans Verkuil1-15/+0
The last user of this 'feature' was the gspca driver. Now that that driver has been converted to vb2 we can delete this code. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

Add a parameter (in the form of a structure to ease future API extensions) to the VSP atomic flush handler to pass CRC source configuration, and pass the CRC value to the completion callback.

The structure is used in the API that the VSP1 driver exposes to the DU driver. Documenting it is thus important.

2018-05-14media: rc: default to idle on at startup or after resetSean Young1-0/+1
Any spaces events received after a reset or startup should be discarded, so ensure the rc device is in idle mode. This also makes it much easier to detect incorrect raw events, as we will do in a following commit.

2018-05-11media: dvbdev: add a mutex protecting the "mdev" pointerMax Kellermann1-0/+2
During destruction, a race condition in dvb_media_controller_disable_source() can cause a kernel crash, because the "mdev" pointer has been read successfully while another task executes dvb_usb_media_device_unregister(), which destroys the object.

The mdev field is only present if CONFIG_MEDIA_CONTROLLER is set. But since we will need to pass the media_device to vb2 and the control framework it is very convenient to just make this field available all the time. If CONFIG_MEDIA_CONTROLLER is not set, then it will just be NULL.

Pull media fixes from Mauro Carvalho Chehab: "A series of media updates/fixes for 4.17. There are two important core fix patches in this series: - A regression fix on Kernel 4.16 with causes it to not work with some input devices that depend on media core - A fix at compat32 bits with causes it to OOPS on overlay, and affects the Kernels where the CVE-2017-13166 was backported The remaining ones are other random fixes at the documentation and on drivers. The biggest part of this series is a set of 18 patches for the Intel atomisp driver. Currently, it produces hundreds of warnings/errors on sparse/smatch, causing me to sometimes ignore new warnings on other drivers that are not so broken. This driver is on really poor state, even for staging standards: it has several layers of abstraction on it, and it supports two different hardware. Selecting between them require to add a define (there isn't even a Kconfig option for such purpose). Just on this smatch cleanup, I could easily get rid of 8 "do-nothing" files. So, I'm seriously considering its removal from upstream, if I don't see any real work on addressing the problems there along this year" * tag 'media/v4.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (48 commits) media: v4l2-core: fix size of devnode_nums[] bitarray media: v4l2-compat-ioctl32: don't oops on overlay media: i2c: adv748x: afe: fix sparse warning media: extended-controls.rst: transmitter -> receiver media: staging: atomisp: stop duplicating input format types media: staging: atomisp: get rid of an unused var media: staging: atomisp: stop mixing enum types media: staging: atomisp: get rid of some static warnings media: staging: atomisp: use %p to print pointers media: staging: atomisp: remove an useless check media: staging: atomisp: avoid a warning if 32 bits build media: staging: atomisp: don't access a NULL var media: staging: atomisp: Get rid of *default.host.[ch] media: staging: atomisp: get rid of an unused function media: staging: atomisp: remove unused set_pd_base() media: staging: atomisp: fix endianess issues media: staging: atomisp: add a missing include media: staging: atomisp: get rid of stupid statements media: staging: atomisp: declare static vars as such media: staging: atomisp: ia_css_output.host: don't use var before check ...

2018-03-22media: cec: improve CEC pin event handlingHans Verkuil1-3/+4
It turns out that the struct cec_fh event buffer size of 64 events (64 for CEC_EVENT_PIN_CEC_LOW and 64 for _HIGH) is too small. It's about 160 ms worth of events and if the Raspberry Pi is busy, then it might take too long for the application to be scheduled so that it can drain the pending events. Increase these buffers to 800 events which is at least 2 seconds worth of events. There is also a FIFO in between the interrupt and the cec-pin thread. The thread passes the events on to the CEC core. It is important that should this FIFO fill up the cec core will be informed that events have been lost so this can be communicated to the user by setting CEC_EVENT_FL_DROPPED_EVENTS. It is very hard to debug CEC problems if events were lost without informing the user of that fact. If events were dropped due to the FIFO filling up, then the debugfs status file will let you know how many events were dropped.

Add two new ops (error_inj_show and error_inj_parse_line) to support error injection functionality for CEC adapters. If both are present, then the core will add a new error-inj debugfs file that can be used to see the current error injection commands and to set error injection commands.

2018-03-21media: add tuner standby op, use where neededHans Verkuil1-0/+4
The v4l2_subdev core s_power op was used for two different things: power on/off sensors or video decoders/encoders and to put a tuner in standby (and only the tuner!). There is no 'tuner wakeup' op, that's done automatically when the tuner is accessed. The danger with calling (s_power, 0) to put a tuner into standby is that it is usually broadcast for all subdevs. So a video receiver subdev that supports s_power will also be powered off, and since there is no corresponding (s_power, 1) they will never be powered on again. In addition, this is specifically meant for tuners only since they draw the most current. This patch adds a new tuner op called 'standby' and replaces all calls to (core, s_power, 0) by (tuner, standby). This prevents confusion between the two uses of s_power. Note that there is no overlap: bridge drivers either just want to put the tuner into standby, or they deal with powering on/off sensors. Never both. This also makes it easier to replace s_power for the remaining bridge drivers with some PM code later. Whether we want something cleaner for tuners in the future is a separate topic. There is a lot of legacy code surrounding tuners, and I am very hesitant about making changes there.
