Maybe Alex can confirm how he would rather see it done. >> In amdgpu_isp all we are doing is: (a) load isp fw (b) add isp as MFD device; and anything specific to IP version 4.1.x is taken care in the v4l2 isp driver. We can consider adding private implementation for each ISP ip version in amdgpu if it requires special handling on top of the generic amdgpu_isp + mfd changes. Please let us know your thoughts.

We should show exactly one message for problems like this. Since it's not fatal I think we should only show the DRM_WARN() message. > + amdgpu_ucode_release(&adev->isp.fw); > + return r; > + } > + > + hdr = (const struct common_firmware_header *)adev->isp.fw->data; > + > + adev->firmware.ucode[AMDGPU_UCODE_ID_ISP].ucode_id = > + AMDGPU_UCODE_ID_ISP; > + adev->firmware.ucode[AMDGPU_UCODE_ID_ISP].fw = adev->isp.fw; > + > + adev->firmware.fw_size += > + ALIGN(le32_to_cpu(hdr->ucode_size_bytes), PAGE_SIZE); > + > + return r; > +} > + > +static int isp_early_init(void *handle) { > + int ret = 0; > + struct amdgpu_device *adev = (struct amdgpu_device *)handle; > + > + ret = isp_load_fw_by_psp(adev); > + if (ret) { > + DRM_WARN("%s: isp fw load failed %d\n", __func__, ret); > + /* allow amdgpu init to proceed though isp fw load fails */ > + ret = 0; > + } > + > + return ret; > +} > + > +static bool isp_is_idle(void *handle) { > + return true; > +} > + > +static int isp_wait_for_idle(void *handle) { > + return 0; > +} > + > +static int isp_soft_reset(void *handle) { > + return 0; > +} > + > +static int isp_set_clockgating_state(void *handle, > + enum amd_clockgating_state state) { > + return 0; > +} > + > +static int isp_set_powergating_state(void *handle, > + enum amd_powergating_state state) { > + return 0; > +} > + > +static const struct amd_ip_funcs isp_ip_funcs = { > + .name = "isp_ip", > + .early_init = isp_early_init, > + .late_init = NULL, > + .sw_init = isp_sw_init, > + .sw_fini = isp_sw_fini, > + .hw_init = isp_hw_init, > + .hw_fini = isp_hw_fini, > + .suspend = isp_suspend, > + .resume = isp_resume, > + .is_idle = isp_is_idle, > + .wait_for_idle = isp_wait_for_idle, > + .soft_reset = isp_soft_reset, > + .set_clockgating_state = isp_set_clockgating_state, > + .set_powergating_state = isp_set_powergating_state, }; > + > +const struct amdgpu_ip_block_version isp_ip_block = { > + .type = AMD_IP_BLOCK_TYPE_ISP, > + .major = 4, > + .minor = 1, > + .rev = 0, > + .funcs = &isp_ip_funcs, > +}; I think this is the wrong place for this isp_ip_block and also it should be named differently. Maybe it should be named isp_ip_block_v4_1 and then in a different file?
