Disable verbose while getting p2p distance. With verbose, it shows warning if ACS redirect is set between the devices. Adds noise to dmesg logs when a few GPU devices are on the same platform.Example log: amdgpu 0000:34:00.0: ACS redirect is set between the client and provider (0000:31:00.0) amdgpu 0000:34:00.0: to disable ACS redirect for this path, add the kernel parameter: pci=disable_acs_redir=0000:30:00.0;0000:2e:00.0;0000:33:00.0;0000:2e:10.0 Signed-off-by: Lijo Lazar <lijo.la...@amd.com>
