This will hopefuly help in answering questions like is HDR supported with Software ISP or is Auto Focus supported on Raspberry Pi? This matrix will be regularly updated as new features and platforms are added. Acked-by: Kieran Bingham Signed-off-by: Jai Luthra Reviewed-by: Stefan Klug --- Changes since v2: - Add Kieran's Ack - Fix stray "=" - Split RkISP1 into i.MX8MP and RK3399/3288 as they support slightly different features - Modify the platform names in the table, and add a note just below the table, also dropping the platform notes section later. - Link to v2: https://patchwork.libcamera.org/patch/25156/ --- Documentation/index.rst | 1 + Documentation/isp-feature-matrix.rst | 103 +++++++++++++++++++++++++++ Documentation/meson.build | 1 + 3 files changed, 105 insertions(+) create mode 100644 Documentation/isp-feature-matrix.rst -- 2.51.1 diff --git a/Documentation/index.rst b/Documentation/index.rst index febd4e13..a74b8668 100644 --- a/Documentation/index.rst +++ b/Documentation/index.rst @@ -9,6 +9,7 @@ Introduction Feature Requirements Runtime configuration + ISP feature support matrix Application Writer's Guide Python Bindings Public API diff --git a/Documentation/isp-feature-matrix.rst b/Documentation/isp-feature-matrix.rst new file mode 100644 index 00000000..76eb9dbc --- /dev/null +++ b/Documentation/isp-feature-matrix.rst @@ -0,0 +1,103 @@ +..
