On a DT-base PCI platform, the sysfs path of vga device is like this: /sys/devices/platform/bus@10000000/1a000000.pci/pci0000:00/0000:00:11.0/0000:04:00.0. Then the ID_PATH from udev is platform-1a000000.pci-pci-0000:04:00.0 and the BusID will be pci-0000:04:00.0, which causes Xorg start fail. This is because config_udev_odev_setup_attribs() use strstr() to search the first "pci-" in ID_PATH. To fix this, we implement a strrstr() function and use it to search the last "pci-" in ID_PATH, which can get a correct BusID. Signed-off-by: Huacai Chen <chenhc@lemote.com> |

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
