Use the mirrored topology info to fill links for VF. The new solution is required to simplify and optimize host driver logic. Only use the new solution for VFs that support full duplex and extended_peer_link_info otherwise the info would be incomplete. 2. avoid calling extended_link_info on VF as its not supported Signed-off-by: Vignesh Chander Reviewed-by: Zhigang Luo Reviewed-by: Jonathan Kim Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c index a21045d018f2..1bf975b8d083 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c @@ -1433,8 +1433,8 @@ int psp_xgmi_get_topology_info(struct psp_context *psp, get_extended_data) || amdgpu_ip_version(psp->adev, MP0_HWIP, 0) == IP_VERSION(13, 0, 6); - bool ta_port_num_support = psp->xgmi_context.xgmi_ta_caps & - EXTEND_PEER_LINK_INFO_CMD_FLAG; + bool ta_port_num_support = amdgpu_sriov_vf(psp->adev) ? 0 : + psp->xgmi_context.xgmi_ta_caps & EXTEND_PEER_LINK_INFO_CMD_FLAG; /* popluate the shared output buffer rather than the cmd input buffer * with node_ids as the input for GET_PEER_LINKS command execution. -- cgit v1.2.3 From c572abffe9f50c8ba33060865449313b3f588c35 Mon Sep 17 00:00:00 2001 From: Le Ma Date: Wed, 3 Jan 2024 15:27:38 +0800 Subject: drm/amdgpu: add param to specify fw bo location for front-door loading This param can help isolating data path issues on new systems in early phase.
