We encounter a unexpected error on chrome book device while running kms_busy test. It will restore GPU engine's timeout value but open incorrect file name (XR24 in below).
openat(AT_FDCWD, "/sys/dev/char/226:0", O_RDONLY) = 12 openat(12, "dev", O_RDONLY) = 13 read(13, "226:0\n", 1023) = 6 close(13) = 0 openat(12, "engine", O_RDONLY) = 13 close(12) = 0 openat(13, "XR24", O_RDONLY) = -1 ENOENT (No such file or directory) Test code did not save engine data properly to cause this problem. So modify the code to save GPU engine information into a globla variable to avoid test deamon to open incorrect file again.
