media: platform: amd: isp4 subdev and firmware loading handling addedIsp4 sub-device is implementing v4l2 sub-device interface. It has onecapture video node, and supports only preview stream. It manages firmwarestates, stream configuration.

Wed, 06 May 2026 11:32:45 +0200

media: platform: amd: Add isp4 fw and hw interfaceISP firmware controls ISP HW pipeline using dedicated embedded processorcalled ccpu. The communication between ISP FW and driver is using commandsand response messages sent through the ring buffer. Command buffers supporteither global setting that is not specific to the stream and support streamspecific parameters. Response buffers contain ISP FW notificationinformation such as frame buffer done and command done. IRQ is used forreceiving response buffer from ISP firmware, which is handled in the mainisp4 media device. ISP ccpu is booted up through the firmware loadinghelper function prior to stream start. Memory used for command buffer andresponse buffer needs to be allocated from amdgpu buffer manager becauseisp4 is a child device of amdgpu.Co-developed-by: Sultan Alsawaf Signed-off-by: Sultan Alsawaf Co-developed-by: Svetoslav Stoilov Signed-off-by: Svetoslav Stoilov Signed-off-by: Bin Du Reviewed-by: Sultan Alsawaf Tested-by: Alexey Zagorodnikov Tested-by: Kate Hsuan Signed-off-by: Sakari Ailus List of files: /linux/drivers/media/platform/amd/isp4/Makefile

media: platform: amd: Introduce amd isp4 capture driverAMD isp4 capture is a v4l2 media device which implements media controllerinterface. It has one sub-device (AMD ISP4 sub-device) endpoint which canbe connected to a remote CSI2 TX endpoint. It supports only one physicalinterface for now.
