From deeb956c40e3b6f8ab95f7b53f148a836cf93da2 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Fri, 5 Nov 2021 20:25:41 +0100 Subject: [PATCH] trace-events,pci: unify trace events format MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Unify format used by trace_pci_update_mappings_del(), trace_pci_update_mappings_add(), trace_pci_cfg_write() and trace_pci_cfg_read() to print the device name and bus number, slot number and function number. For instance: pci_cfg_read virtio-net-pci 00:0 @0x20 -> 0xffffc00c pci_cfg_write virtio-net-pci 00:0 @0x20 <- 0xfea0000c pci_update_mappings_del d=0x555810b92330 01:00.0 4,0xffffc000+0x4000 pci_update_mappings_add d=0x555810b92330 01:00.0 4,0xfea00000+0x4000 becomes pci_cfg_read virtio-net-pci 01:00.0 @0x20 -> 0xffffc00c pci_cfg_write virtio-net-pci 01:00.0 @0x20 <- 0xfea0000c pci_update_mappings_del virtio-net-pci 01:00.0 4,0xffffc000+0x4000 pci_update_mappings_add virtio-net-pci 01:00.0 4,0xfea00000+0x4000 Signed-off-by: Laurent Vivier Message-Id: <20211105192541.655831-1-lvivier@redhat.com> Reviewed-by: Philippe Mathieu-Daudé Reviewed-by: Yanan Wang Reviewed-by: Michael S.
