The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0640/1085] media: rp1: cfe: Fix width & height in
|
|
cfe_start_channel()
|
|
|
|
The logic for handling width & height in cfe_start_channel() is somewhat
|
|
odd and, afaics, broken. The code reads:
|
|
|
|
bool start_fe = is_fe_enabled(cfe) &&
|
|
test_all_nodes(cfe, NODE_ENABLED, NODE_STREAMING);
|
|
|
|
if (start_fe || is_image_output_node(node)) {
|
|
width = node->fmt.fmt.pix.width;
|
|
height = node->fmt.fmt.pix.height;
|
|
}
|
|
|
|
cfe_start_channel() is called for all video nodes that will be used. So
|
|
this means that if, say, fe_stats is enabled as the last node, start_fe
|
|
will be true, and width and height will be taken from fe_stats' node.
|
|
The width and height will thus contain garbage, which then gets
|
|
programmed to the csi2 registers.
|
|
|
|
It seems that this often still works fine, though, probably if the width
|
|
& height are large enough.
|
|
|
|
Drop the above code, and instead get the width & height from the csi2
|
|
subdev's sink pad for the csi2 channel that is used. For metadata the
|
|
width & height will be 0 as before.
