Hi~ all, I try to run the test pm_backlight. But there is an skip with the log as following. ```` IGT-Version: 1.19-g4258cc8e (x86_64) (Linux: 4.10.0 x86_64) Test
requirement not met in function __real_main154, file pm_backlight.c:163:
Test requirement: !(backlight_read(&old, "brightness")) Last errno: 2,
No such file or directory ```` By my check there is not a file in dir /sys/class/backlight/ I wander is there any kconfig or boot parameters need to set? I have tried adding “acpi_ osi=Linux acpi_backlight=vendor” to GRUB config, but it’s same as before. Thank you! |
