How to find which process is using it ? Kernel reports which module is using it. For processes... it's not as easy. If there's a device node, you could search for the processes with that node opened. Example: └ ~ ➤ lsmod | grep drm drm_kms_helper 35710 1 i915 drm 239102 5 i915,drm_kms_helper i2c_core 24760 6 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,videodev └ ~ ➤ lsof /dev/dri/card0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME gnome-she 589 lucas mem CHR 226,0 8096 /dev/dri/card0 gnome-she 589 lucas 9u CHR 226,0 0t0 8096 /dev/dri/card0 chromium 22801 lucas mem CHR 226,0 8096 /dev/dri/card0 chromium 22801 lucas 11u CHR 226,0 0t0 8096 /dev/dri/card0 chromium 22805 lucas 11u CHR 226,0 0t0 8096 /dev/dri/card0 -- Lucas De Marchi -- To unsubscribe from this list: send the line "unsubscribe linux-modules" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
