Nvidia Kernel Channel



Background

Relatively rarely but often enough to be a problem we see a kernel NULL pointer dereference or failed paging request. The error occurs in one of three locations (see failure points below). The problem seems to only occur on some exceptional condition (i.e. syncpt timeout). If the stream is completely nominal then we do not see this issue.

Hypothesis

The nvidia v4l2 camera driver contains a race condition in tegra/camera/channel.c. The struct tegra_channel contains a four-element ring buffer of struct vb2_buffer objects. The driver utilizes two kernel threads: the capture thread starts a frame capture, and the release thread concludes a frame capture. Nominally they operate on a shared ring buffer. One thread writes elements into the buffer, and the other thread reads elements out of the buffer. However both threads have some error condition where they reset the buffer, and I believe that this unsynchronized reset is the problem. My hypothesis is that one thread resets the buffer while another thread is in the process of reading/writing to it.

In particular it appears that the purpose of this buffer is to indicate "this is the set of frames to discard if we need to reset". It includes the set of frames that are in release as well as potentially one frame that is on it's way to begin capture.

Solution

The requirement satisfied by the buffer solution is the following: If an error is returned at either the soc_camera_capture_frame() or soc_camera_release_frame() calls, then the VI will be reset and so it doesn't make sense to keep processing frames. Some specific examples:

  • If there is a syncpt timeout error in the release thread while waiting for the frame to finish then we want the capture thread to reset, and any frames currently in flight we want to be released immediately without passing them to the VI.
  • If there is a frame start error in the capture thread, then will reset the VI so we want to flush any frames that are "in flight" without waiting for the VI to finish filling them.

One way of solving this is to keep track of an atomic reset_version integer. When the capture thread restarts the stream, it increments this count. Each time it starts capture on a buffer it stamps the buffer with the current reset_version. Ever time the release thread starts to wait on a frame, it verifies that the reset_version of the buffer matches the current reset_version. If it is different, it flushes the buffer without waiting for it to finish receiving (because it was queued before the VI was reset). Every time the capture thread preps a buffer for capture it checks to see if the reset_version has changed. If it has, then it will reset the VI first.

Failure points

There are two kernel threads. One to capture data to buffer, and a second to release the buffer. Presumably they do their work at start of frame and at end of frame.

The entry points for the two threads are

  • tegra_channel_kthread_capture_start():
  • tegra_channel_kthread_release():

However note that some of the functions executed here might actually be executed in a third thread. For instance (stack 1) to indicate it's actually the userspace thread calling into an ioctl that is leading to the call.

The crash seems to generally occur in one of these three places. My hypothesis is that there is race condition, due to the fact that we see the error consistently on a failed stream closure.

Program flow

Life of a buffer

posts/2018/nvidia_kernel_channel/nvidia_kernel_channel.svg

Life of a buffer

  • tegra_channel_buffer_queue(): inserts a buffer into capture
    • buf_queue member of vb2_ops, I believe this is called throught he v4l2 ioctl to enqueue a buffer.
  • dequeue_buffer(): removes a buffer from capture and adds it to buffer
  • tegra_channel_ring_buffer(): nominally adds a buffer release, but may also call free_ring_buffers()
  • tegra_channel_kthread_release: removes a frame from release
  • free_ring_buffers(): removes a buffer from buffer and marks it as done, I believe returning it to v4l2 and allowing it to be retreived with the v4l2 ioctl to dequeue a buffer.

Capture thread

The capture thread loop is basically:

  • dequeue_buf(): Retrieve a buffer that is ready to be filled
  • tegra_channel_capture_frame(chan, buf): Start filling the buffer with frame data.

Release thread

The release thread is basically

  • list_del_init(&buf->queue): remove the buffer from the chan->release list
  • tegra_channel_release_frame(chan, buf): release the frame to userspace

Frame Buffers

The vb2 buffer objects are stored in the buffers field of the struct tegra_channel. This is a fixed size array of four elements. It is used as a ring buffer through the indices save_index and free_index:

  • ``save_index``: The "write" head of the ring buffer. If we need to add an element to the ring this is where we add it, and the increment (with wrap-around).
  • ``free_index``: THe "read" head of the ring buffer. If we want to remove an element of the ring this where we remove from, and increment (with wrap-around).

Possible races

``free_ring_buffers()``, called by:

  • capture thread:
    • stack 1 (CAPTURE_ERROR)
      • free_ring_buffers()
      • tegra_channel_ring_buffer()
      • tegra_channel_capture_frame()
      • tegra_channel_kthread_capture_start()
    • stack 2 (capture state unspecified)
      • free_ring_buffers()
      • tegra_channel_ring_buffer()
      • tegra_channel_capture_frame()
      • tegra_channel_kthread_capture_start()
  • release thread
    • stack 1 (CAPTURE_SUCCESS):
      • free_ring_buffers()
      • tegra_channel_release_frame()
    • stack 2 (CAPTURE_TIMEOUT):
      • free_ring_buffers()
      • tegra_channel_ring_buffer()
      • tegra_channel_release_frame()
  • v4l userspace thread:
    • stack 1 (CAPTURE_GOOD)
      • free_ring_buffers()
      • tegra_channel_ring_buffer()
      • tegra_channel_capture_done()
      • tegra_channel_stop_streaming()
    • stack 2 (always)
      • free_ring_buffers()
      • tegra_channel_stop_streaming()

``add_buffer_to_ring()``, called by:

  • stack 1
    • add_buffer_to_ring()
    • dequeue_buffer()
    • tegra_channel_capture_done()
    • tegra_channel_stop_streaming()
  • stack 2
    • add_buffer_to_ring()
    • dequeue_buffer()
    • tegra_channel_kthread_capture_start()

Some relevant notes:

  • tegra_channel_stop_streaming() calls tegra_channel_stop_kthreads() before it calls free_ring_buffers() and tegra_channel_stop_threads() does wait on a completion indicating the thread has exited before it continues.
  • that tegra_channel_ring_buffer is called by both tegra_channel_capture_frame() and tegra_channel_release_frame() so there is a second path to free_ring_buffers() from the release thread.
  • tegra_channel_ring_buffer() takes a int state argument, which is not used. I suspect the intent was to communicate the capture state, but this is stored instead in chan->capture_state (where chan is a struct tegra_channel).
  • Unable to handle kernel paging request at virual address... is likely an indicator of a corrupt stack. Perhaps a buffer overflow. The dead address prefix likely indicates that the pointer was cleared out or invalidated somehow (i.e. free()ed?
  • Several functions will set chan->capture_state to something other than CAPTURE_GOOD but there are no functions in channel.c that set it to CAPTURE_GOOD. This is done instead in vi2_channel_capture_frame() defined in vi2_fops.c. This function is assigned as the soc_channel_capture_frame member of the chan->fops vtable which is called at the end of tegra_channel_enable_stream().
  • If free_ring_buffers() is called from tegra_channel_ring_buffer() or tegra_channel_stop_streaming() then the number of buffers to free is chan->num_buffers. If called from tegra_channel_release_frame() then the number of buffers to free is one.

Some notes on kernel code

Freezing of tasks

From here

This is how user space processes and some kernel threads are controlled during hybernation or system-wide susped.

All freezable tasks must react to that by calling try_to_freeze(), which results in a call to __refrigerator() (defined in kernel/freezer.c), which sets the task's PF_FROZEN flag, changes its state to TASK_UNINTERRUPTIBLE and makes it loop until PF_FROZEN is cleared for it.

Sleeping

From here

The preferred alternative is wait_event_interruptible, which can be interrupted by signals. This version returns an integer value that you should check; a nonzero value means your sleep was interrupted by some sort of signal, and your driver should probably return -ERESTARTSYS.

In particular tegra_channel_kthread_capture_start sleeps until the following condition is true:

!list_empty(&chan->capture) || kthread_should_stop()

Which I interpret to mean, in english "Sleep until there is a buffer available to fill we are supposed to die."

Completion

From here

Completions are a code synchronization mechanism which is preferable to any misuse of locks. Any time you think of using yield() or some quirky msleep(1) loop to allow something else to proceed, you probably want to look into using one of the wait_for_completion*() calls instead. The advantage of using completions is clear intent of the code, but also more efficient code as both threads can continue until the result is actually needed.

Spin Locks

From here

Spinlocks are simple in concept. A spinlock is a mutual exclusion device that can have only two values: "locked" and "unlocked." It is usually implemented as a single bit in an integer value. Code wishing to take out a particular lock tests the relevant bit. If the lock is available, the "locked" bit is set and the code continues into the critical section. If, instead, the lock has been taken by somebody else, the code goes into a tight loop where it repeatedly checks the lock until it becomes available. This loop is the "spin" part of a spinlock.

List Operations

list_for_each_entry_safe doesn't really indicate whether or not the list may be empty. I think the answer is no (otherwise, it's not a well formed list). In particular, note that tegra_channel_kthread_release() and dequeue_buffer() both check !list_empty(...) instead of just iterating under the assumption that it is non-empty. list_entry get the struct for this entry
