2023-05-04pipeline: ipa: raspberrypi: Refactor and move the Raspberry Pi codeNaushir Patuck
Split the Raspberry Pi pipeline handler and IPA source code into common and VC4/BCM2835 specific file structures. For the pipeline handler, the common code files now live in src/libcamera/pipeline/rpi/common/ and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/. For the IPA, the common code files now live in src/ipa/rpi/{cam_helper,controller}/ and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/. To build the pipeline and IPA, the meson configuration options have now changed from "raspberrypi" to "rpi/vc4": meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4 Signed-off-by: Naushir Patuck <naush@raspberrypi.com> Reviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2023-04-05libcamera: Open files with O_CLOEXECLaurent Pinchart
Files opened internally in libcamera without the O_CLOEXEC file will remain open upon a call to one of the exec(3) functions. As exec() doesn't destroy local or global objects, this can lead to various side effects. Avoid this by opening file descriptors with O_CLOEXEC for all internal files.

2021-12-04libcamera: pipeline: raspberrypi: DmaHeaps: Use UniqueFD for a file descriptorHirokazu Honda
Manages a file descriptor owned by DmaHeaps for a dma handle by UniqueFD. Furthermore, DmaHeaps::alloc() creates a new file descriptor and the returned file descriptor is owned by a caller. This also clarifies it by changing the returned value to UniqueFD.

2021-06-25libcamera/base: Move extended base functionalityKieran Bingham
Move the functionality for the following components to the new base support library: - BoundMethod - EventDispatcher - EventDispatcherPoll - Log - Message - Object - Signal - Semaphore - Thread - Timer While it would be preferable to see these split to move one component per commit, these components are all interdependent upon each other, which leaves us with one big change performing the move for all of them.

2020-08-28libcamera: raspberrypi: dmaheaps: Improve device openJacopo Mondi
Improve the device opening at class construction time by testing all the available device paths and printout the appropriate error message. While at it, initialize dmaHeapHandle_ to -1 and check for its value at destruction time.

2020-07-17libcamera: pipeline: ipa: raspberrypi: Use dma heap allocs for LS tablesNaushir Patuck
Remove use of vcsm allocations and replace with dma heap allocations. The pipeline handler now passes the fd of the allocation over to the IPA instead of the raw pointer. Also use libcamera::FileDescriptor for fd lifetime management. This commit must be built alongside the accompanying BCM2835 ISP kernel driver changes at https://github.com/raspberrypi/linux/pull/3715. Otherwise a mismatch will cause undefined behavior.
