2024-06-03test: fence: Increase timeout for fence testLaurent Pinchart
On slower machines, a 1s timeout to capture frames with vimc can be too short and cause test failures. Make the timeout proportional to the number of frames expected to be captured, using a conservative low estimate of the frame rate at 2fps. By itself, that change could increase the test time quite substantially on fast platforms, so break from the capture loop as soon as we capture enough frames.

2024-06-03test: fence: Fix race conditionLaurent Pinchart
The fence test is racy, as it relies on the main loop being executed between completion of request signalledRequestId_ and signalledRequestId_ + 1. This usually happens, but is not guaranteed. To fix the race condition, change the request identification logic by replacing usage of the cookie value, which is zero-based and wraps around at nbuffers_ - 1, with a completed request counter that is one-based and doesn't wrap. The completedRequestId_, expiredRequestId_ and signalledRequestId_ variables now track the identifier of the last request that has completed, the request whose fence will time out, and the request whose fence will be signalled.

2024-05-08libcamera: Drop file name from header comment blocksLaurent Pinchart
Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it. Drop the file name from the header comment block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header. Those will be addressed separately and manually. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>
2022-03-25libcamera: base: timer: Drop start() overload with int argumentLaurent Pinchart
The start(unsigned int msec) overload is error-prone, as the argument unit can easily be mistaken in callers. Drop it and update all callers to use the start(std::chrono::milliseconds) overload instead. The callers now need to use std::chrono_literals. The using statement could be added to timer.h for convenience, but "using" is discouraged in header files to avoid namespace pollution. Update the callers instead, and while at it, sort the "using" statements alphabetically in tests.

2021-12-13test: fence: Signal fence onceJacopo Mondi
The unit test associates a fence with a framebuffer and makes sure the fence is correctly signalled. Once a fence is correctly signalled, it is released by the core, and the underlying file descriptor closed. The unit test however tries to write on the fence file descriptor every time the designated Request is queued, an error which is now visible as the return value of the fence signalling write() is checked. Fix that by associating a fence with a framebuffer only once.

The ::write() function used to signal a framebuffer fence in the unit test is marked with the 'warn_unused_result'. When building in debugoptimized mode not checking for the return value causes issues at build time: /test/fence.cpp:254:2: error: ignoring return value of function declared with 'warn_unused_result' attribute Fix that by checking the ::write() return value and emitting an error message in case the write fails.
