Let's make this range configurable.\n\nFor this purpose, this patch introduces new configuration options\npipelines.simple.measure.skip and pipelines.simple.measure.number.\nSetting the latter one to 0 disables the measurement.\n\nInstead of the last frame, the class member and its configuration\nspecify the number of frames to measure. This is easier to use for\nusers and doesn't require to adjust two configuration parameters when\nthe number of the initially skipped frames is changed.\n\nThe patch also changes the names of the class members to make them more\naccurate.\n\nCompletes software ISP TODO #7.\n\nSigned-off-by: Milan Zamazal <mzamazal@redhat.com>\n---\n Documentation/runtime_configuration.rst | 6 ++++++\n src/libcamera/software_isp/TODO | 25 ----------------------\n src/libcamera/software_isp/debayer_cpu.cpp | 25 ++++++++++++++--------\n src/libcamera/software_isp/debayer_cpu.h | 7 +++---\n 4 files changed, 25 insertions(+), 38 deletions(-)", "diff": "diff --git a/Documentation/runtime_configuration.rst b/Documentation/runtime_configuration.rst\nindex d439fa21..943f8876 100644\n--- a/Documentation/runtime_configuration.rst\n+++ b/Documentation/runtime_configuration.rst\n@@ -54,6 +54,9 @@ file structure:\n config_file: # full path\n simple:\n copy_input_buffer: # true/false\n+ measure:\n+ skip: # non-negative integer, frames to skip initially\n+ number: # non-negative integer, frames to measure\n supported_devices:\n - driver: # driver name, e.g. `mxc-isi`\n software_isp: # true/false\n@@ -90,6 +93,9 @@ Configuration file example\n config_file: /usr/local/share/libcamera/pipeline/rpi/vc4/minimal_mem.yaml\n simple:\n copy_input_buffer: false\n+ measure:\n+ skip: 50\n+ number: 30\n supported_devices:\n - driver: mxc-isi\n software_isp: true\ndiff --git a/src/libcamera/software_isp/TODO b/src/libcamera/software_isp/TODO\nindex 2c919f44..f19e15ae 100644\n--- a/src/libcamera/software_isp/TODO\n+++ b/src/libcamera/software_isp/TODO\n@@ -71,31 +71,6 @@ per-frame buffers like we do for hardware ISPs.\n \n ---\n \n-7.
