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. Signed-off-by: Jai Luthra --- Changes since v1: - Use restructuredText grid table instead of list table - Update bcm2711/bcm2712 with Naush's inputs - Add the new document in the index - Reword the Platform Notes section - Link to v1: https://patchwork.libcamera.org/patch/24438/ I will send a separate patch for the sensor support table --- Documentation/index.rst | 1 + Documentation/isp-feature-matrix.rst | 102 +++++++++++++++++++++++++++ Documentation/meson.build | 1 + 3 files changed, 104 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..6791dc96 --- /dev/null +++ b/Documentation/isp-feature-matrix.rst @@ -0,0 +1,102 @@ +..
