| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using an activation counter to decide when the enable or disable the cec adapter is not the best approach and can lead to race conditions. Change this to determining the current status of the adapter, and enable or disable the adapter accordingly. It now only needs to be called whenever there is a chance that the state changes, and it can handle enabling/disabling monitoring as well if needed. This simplifies the code and it should be a more robust approach as well. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

If during that process the cable is disconnected (HPD goes low, which in turn invalidates the physical address), then cec_adap_unconfigure() is called, and that set the is_configuring boolean to false, even though the thread that's trying to claim an LA is still running. Don't touch the is_configuring bool in cec_adap_unconfigure(), it will eventually be cleared by the thread. By making that change the cec_config_log_addr() function also had to change: it was aborting if is_configuring became false (since that is what cec_adap_unconfigure() did), but that no longer works. Instead check if the physical address is invalid. That is a much more appropriate check anyway. This fixes a bug where the the adapter could be disabled even though the device was still configuring. This could cause POLL transmits to time out. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The __cec_s_log_addrs() function can configure or unconfigure the adapter. The ioctl handler in cec-api.c will prevent it from being called to configure the adapter if it was already configured (or in the process of configuring). But it can still be called to unconfigure an already unconfigured adapter, and it didn't check for that. This can cause cec_activate_cnt_dec() to be called too often, causing a WARN_ON. Instead first check if adap->log_addrs.num_log_addrs == 0 and return since in that case the adapter is already unconfigured.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's OK to keep the pending pin events when disabling or enabling the 'adapter'. Zeroing this can cause a race condition if this happens when the pin kthread is handling a pin event and calls atomic_dec later, causing work_pin_num_events to become negative.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the adap_enable callback is called the adap->lock is held. When disabling the adapter it attempts to stop the kthread that deals with receiving and transmitting messages. However, kthread_stop waits for the thread to stop, so all that time adap->lock is held. Unfortunately, the kernel thread itself can call functions that take that same lock, so a deadlock can occur. Change the logic to keep the kernel thread running and instead when disabling the adapter, just set the pin to high, go to idle and then to state OFF and disable the interrupt. Only stop the kernel thread when the adapter is deleted. This way disabling the adapter will not wait for anything and the deadlock is avoided.

Since usb_deregister_dev() from imon_disconnect() holds minor_rwsem while display_open() which holds driver_lock is called with minor_rwsem held, holding driver_lock when calling usb_deregister_dev() also causes circular locking dependency problem. Sean Young explained that the problem is there are imon devices which have two usb interfaces, even though it is one device. The probe and disconnect function of both usb interfaces can run concurrently. Alan Stern responded that the driver and USB cores guarantee that when an interface is probed, both the interface and its USB device are locked. Ditto for when the disconnect callback gets run. So concurrent probing/ disconnection of multiple interfaces on the same device is not possible. Therefore, we don't need locks for handling race between imon_probe() and imon_disconnect(). But we still need to handle race between display_open() /vfd_write()/lcd_write()/display_close() and imon_disconnect(), for disconnect event can happen while file descriptors are in use. Since "struct file"->private_data is set by display_open(), vfd_write()/ lcd_write()/display_close() can assume that "struct file"->private_data is not NULL even after usb_set_intfdata(interface, NULL) was called. Replace insufficiently held driver_lock with refcount_t based management. Add a boolean flag for recording whether imon_disconnect() was already called. Use RCU for accessing this boolean flag and refcount_t. Since the boolean flag for imon_disconnect() is shared, disconnect event on either intf0 or intf1 affects both interfaces. But I assume that this change does not matter, for usually disconnect event would not happen while interfaces are in use.

* | | media: atmel: atmel-isc-base: use mutex to lock awb workq from streamingEugen Hristev2022-05-132-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AWB workqueue runs in a kernel thread and needs to be synchronized w.r.t. the streaming status. It is possible that streaming is stopped while the AWB workq is running. In this case it is likely that the check for vb2_start_streaming_called is done at one point in time, but the AWB computations are done later, including a call to isc_update_profile, which requires streaming to be started. Thus , isc_update_profile will fail if during this operation sequence the streaming was stopped. To solve this issue, a mutex is added, that will serialize the awb work and streaming stopping, with the mention that either streaming is stopped completely including termination of the last frame is done, and after that the AWB work can check stream status and stop; either first AWB work is completed and after that the streaming can stop correctly. The awb spin lock cannot be used since this spinlock is taken in the same context and using it in the stop streaming will result in a recursion BUG.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During experiments with libcamera, it looks like vb2_is_streaming returns true before our start streaming is called. Order of operations is streamon -> queue -> start_streaming ISC would have started the DMA immediately when a buffer is being added to the vbqueue if the queue is streaming. It is more safe to start the DMA after the start streaming of the driver is called. Thus, even if vb2queue is streaming, add the buffer to the dma queue of the driver instead of actually starting the DMA process, if the start streaming has not been called yet. Tho achieve this, we have to use vb2_start_streaming_called instead of vb2_is_streaming.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vertical subsampling factor is currently not considered in the offset calculation for plane cropping done in rpf_configure_partition. This causes a distortion (shift of the color plane) when formats with the vsub factor larger than 1 are used (e.g. NV12, see vsp1_video_formats in vsp1_pipe.c). This commit considers vsub factor for all planes except plane 0 (luminance). Drop generalization of the offset calculation to reduce the binary size.

There are however use cases where drivers can benefit from checking queue ownership, for instance when open-coding an ioctl handler that needs to perform additional checks before calling the corresponding vb2 operation. Expose the vb2_queue_is_busy() function in the videobuf2-v4l2.h header, and change its first argument to a struct vb2_queue pointer as the function name implies it operates on a queue, not a video_device.
