As stated in the commit message,\nthis patch fixes an issue introduced by the imx8-isi multicamera support\npatch, merged in v0.5.2.\n\nIssue is about running multiple processes trying to list cameras while\none process is already using one (or more) camera(s).\n\nTested on i.MX8MP evk.\n\n---\nChanges in v5:\n- Move debug log into PipelineHandler acquire() and release() instead of\n PipelineHandlerISI.\n- Add 'const' after accessor function to mark it as non-mutating, like \n other accessors.\n- Rephrase accessor description as suggested by Barnabás.\n- Fix coding style issue in comments paragraph.\n- Add 'maybe_unused' flag in PipelineHandlerISI::acquireDevice camera\n parameter as it is not used anymore.\n\nlink to v4: https://patchwork.libcamera.org/cover/24950/\n\nChanges in v4:\n- Add an accessor for PipelineHandler::useCount_, and move back the\n variable into private to avoid documentation build issue.\n\nlink to v3: https://patchwork.libcamera.org/cover/24850/\n\nChanges in v3:\n- Move PipelineHandler::useCount_ variable to protected instead of private.\n- Use PipelineHandler::useCount_ variable instead of local acquireCount_.\n- Remove useless PipelineHandlerISI::releaseDevice().\n\nlink to v2: https://patchwork.libcamera.org/patch/24720/ \n\nChanges in v2:\n- Return boolean instead of int if an error is returned by setRouting in\n acquireDevice.\n- Check acquireCount_ is higher than 0 instead of 1, and increase counter\n only when setRouting is successful, or if counter is already non null.\n\nlink to v1: https://patchwork.libcamera.org/patch/24706/\n\n---\nAndrei Gansari (1):\n pipeline: imx8-isi: Delay ISI routes config to acquire() time\n\nAntoine Bouyer (1):\n libcamera: pipeline_handler: Add accessor for useCount_\n\n include/libcamera/internal/pipeline_handler.h | 1 +\n src/libcamera/pipeline/imx8-isi/imx8-isi.cpp | 26 ++++++++++++++-----\n src/libcamera/pipeline_handler.cpp | 14 ++++++++++\n 3 files changed, 35 insertions(+), 6 deletions(-)" }
