The actions and events for IPA <> PH\nhandling is minimalistic for now, can be extended on top.\n\nAs discussed on IRC, absence of actual parameters and\nstatistics buffer is a concern. We could have created our\nown, but those need to be backed by dmabuf/fds. We want\nto leverage VIMC for tests for now, hence, we are passing\nactual frame buffers to the IPA instead of the param/stats\nones.\n\nLaurent Pinchart (1):\n ipa: vimc: Add configure() function\n\nUmang Jain (3):\n ipa: vimc: Rename IPA trace enums\n ipa: vimc: Map and unmap buffers\n ipa: vimc: Send and retrieve FrameBuffers from IPA\n\n include/libcamera/ipa/vimc.mojom | 41 +++++++++++--\n src/ipa/vimc/vimc.cpp | 91 ++++++++++++++++++++++++++--\n src/libcamera/pipeline/vimc/vimc.cpp | 68 ++++++++++++++++++++-\n test/ipa/ipa_interface_test.cpp | 18 +++---\n 4 files changed, 196 insertions(+), 22 deletions(-)"}
