2021-08-16pipeline: vimc: Force complete of request on cancelled buffersUmang Jain
When the stream is stopped, the V4L2VideoDevice sends back all the queued buffers with FrameMetadata::FrameCancelled status. It is the responsibility of the pipeline handler to handle these buffers with FrameMetadata::FrameCancelled. VIMC is currently missing this handling path. As the FrameMetadata::FrameCancelled is set when the stream is stopped, we can be sure that no more queued and re-use of request shall happen. Hence, cancel all the requests' buffers force a complete with completeBuffer(). The issue is caught by the gstreamer_single_stream_test.cpp running with vimc. During the check with meson built-in option '-Db_sanitize=address,undefined' it was observed: ==118003==ERROR: AddressSanitizer: heap-use-after-free on address 0x60e000037108 at pc 0x7f225160c9ac bp 0x7f224a47b620 sp 0x7f224a47b618 READ of size 4 at 0x60e000037108 thread T1 #0 0x7f225160c9ab in libcamera::Request::sequence() const ../include/libcamera/request.h:55 #1 0x7f22518297aa in libcamera::VimcCameraData::bufferReady(libcamera::FrameBuffer*) ../src/libcamera/pipeline/vimc/vimc.cpp:577 #2 0x7f225183b1ef in libcamera::BoundMethodMember<libcamera::VimcCameraData, void, libcamera::FrameBuffer*>::activate(libcamera::FrameBuffer*, bool) ../include/libcamera/base/bound_method.h:194 #3 0x7f22515cc91f in libcamera::Signal<libcamera::FrameBuffer*>::emit(libcamera::FrameBuffer*) ../include/libcamera/base/signal.h:126 #4 0x7f22515c3305 in libcamera::V4L2VideoDevice::streamOff() ../src/libcamera/v4l2_videodevice.cpp:1605 #5 0x7f225181f345 in libcamera::PipelineHandlerVimc::stop(libcamera::Camera*) ../src/libcamera/pipeline/vimc/vimc.cpp:365 The VimcCameraData::bufferReady seems to emit even after the stream is stopped.

2021-08-16ipa: vimc: Send and retrieve FrameBuffers from IPAUmang Jain
Plumb through VIMC mojo interface to enable buffers passing. VIMC does not have parameters or statistics buffers but we can mimick the typical case of passing IPA buffers from pipeline handler to IPA using mock buffers. The mock IPA buffers are FrameBuffers which are dmabuf backed (in other words, mmap()able through MappedFramebuffer inside the IPA). This commits shows: - Passing the parameter buffer from the pipeline handler to the IPA through functions defined in mojom interface. - Passing request controls ControlList to the IPA. Any tests using VIMC will now loop in the IPA paths. Any tests running in isolated mode will help us to test IPA IPC code paths especially around (de)serialization of data passing from pipeline handlers to the IPA. Future IPA interface tests can simply extend the vimc mojom interface to achieve/test a specific use case as required.

2021-08-16pipeline: vimc: Allocate mock IPA buffersUmang Jain
VIMC is a virtual test driver that doesn't have statistics or parameters buffers that are typically passed from a pipeline handler to its platform IPA. To increase the test coverage going forward, we can at least mimick the typical interaction of how a pipeline handler and IPA interact, and use it to increase the test coverage. Hence, create simple (single plane) dmabuf-backed FrameBuffers, which can act as mock IPA buffers and can be memory mapped (mmap) to VIMC IPA. To create these buffers, temporarily hijack the output video node and configure it with a V4L2DeviceFormat. Buffers then can be exported from the output video node using V4L2VideoDevice::exportBuffers(). These buffers will be mimicked as IPA buffers in subsequent commits.

2021-08-14test: gstreamer: Add test for gstreamer single streamVedant Paranjape
This patch adds a test to test if single stream using libcamera's gstreamer element works. We need to work around two distinct issues with ASan when enabled in the build: - glib has a known leak at initialization time. This is covered by the suppression file shipped with glib, but it's not clear how to use it automatically. For now, disable leak detection to avoid test failures. - GStreamer spawns a child process to scan plugins. If GStreamer is compiled without ASan (which is likely) but libcamera is, dlopen()ing the libcamera plugin will cause an ASan link order verification failure. Disable the verification child processes to work around the problem. This requires gcc 8 or newer.

2021-08-12libcamera: ipu3: Initialize controls in the IPAJacopo Mondi
All the IPU3 Camera controls are currently initialized by the pipeline handler which initializes them using the camera sensor configuration and platform specific requirements. However, some controls are better initialized by the IPA, which might, in example, cap the exposure times and frame duration to the constraints of its algorithms implementation. Also, moving forward, the IPA should register controls to report its capabilities, in example the ability to enable/disable 3A algorithms on request. Move the existing controls initialization to the IPA, by providing the sensor configuration and its controls to the IPU3IPA::init() function, which initializes controls and returns them to the pipeline through an output parameter. The existing controls initialization has been copied verbatim from the pipeline handler to the IPA, if not a for few line breaks adjustments and the resulting Camera controls values are not changed.

Introduce a new field in the controls serialization protocol to allow discerning which ControlIdMap a ControlInfoMap refers to. The newly introduced IdMapType enumeration describes the possible info maps: - Either the globally available controls::controls and properties::properties maps, which are valid across IPC boundaries - A ControlIdMap created locally by the V4L2 device, which is not valid across the IPC boundaries At de-serialization time the idMapType field is inspected and - If the idmap is a globally defined one, there's no need to create new ControlId instances when populating the de-serialized ControlInfoMap. Use the globally available map to retrieve the ControlId reference and use it. - If the idmap is a map only available locally, create a new ControlId as it used to happen before this patch. As a direct consequence, this change allows us to perform lookup by ControlId reference on de-serialized ControlIdMap that refers to the libcamera defined controls::controls and properties::properties.

ControlInfoMap does not have a ControlId map associated, but rather creates one with the generateIdMap() function at creation time. As a consequence, when in the need to de-serialize a ControlInfoMap all the ControlId it contains are created by the deserializer instance, not being able to discern if the controls the ControlIdMap refers to are the global libcamera controls (and properties) or instances local to the V4L2 device that has first initialized the controls. As a consequence the ControlId stored in a de-serialized map will always be newly created entities, preventing lookup by ControlId reference on a de-serialized ControlInfoMap. In order to make it possible to use globally available ControlId instances whenever possible, create ControlInfoMap with a reference to an externally allocated ControlIdMap instead of generating one internally. As a consequence the class constructors take and additional argument, which might be not pleasant to type in, but enforces the concepts that ControlInfoMap should be created with controls part of the same id map. As the ControlIdMap the ControlInfoMap refers to needs to be allocated externally: - Use the globally available controls::controls (or properties::properties) id map when referring to libcamera controls - The V4L2 device that creates ControlInfoMap by parsing the device's controls has to allocate a ControlIdMap - The ControlSerializer that de-serializes a ControlInfoMap has to create and store the ControlIdMap the de-serialized info map refers to Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
