Hi all, (always trying to lower cpu temp)
kldloading drm and i915 has come to my attention this log line: error: [drm:pid-1:csr_load_work_fn] *ERROR* Failed to load DMC firmware [ https://01.org/linuxgraphics/intel-linux-graphics-firmwares], disabling runtime power management. Is this a normal behaviour in DFly? from messages: Sep 16 09:04:35 amidatacyber730 kernel: drm1 on vgapci1 Sep 16 09:04:35 amidatacyber730 kernel: [drm] pdev: vendor=0x8086 device=0x191b rev=0x06 Sep 16 09:04:35 amidatacyber730 kernel: [drm] svendor=0x17aa sdevice=0x5050 irq=17 Sep 16 09:04:35 amidatacyber730 kernel: _pci_get_rle: dinfo was NULL, trying again with parent Sep 16 09:04:35 amidatacyber730 kernel: pci_resource_len(0x191b, 0x10) = 0x1000000 Sep 16 09:04:35 amidatacyber730 kernel: WARN_ON(domain->wake_count == 0)<4>WARN_ON(domain->wake_count == 0)<4>WARN_ON(domain->wake_count == 0)_pci_get_rle: dinfo was NULL, trying again with parent Sep 16 09:04:35 amidatacyber730 kernel: pci_resource_len(0x191b, 0x18) = 0x10000000 Sep 16 09:04:35 amidatacyber730 kernel: _pci_get_rle: dinfo was NULL, trying again with parent Sep 16 09:04:35 amidatacyber730 kernel: pci_resource_len(0x191b, 0x10) = 0x1000000 Sep 16 09:04:35 amidatacyber730 kernel: [drm] Memory usable by graphics device = 4096M Sep 16 09:04:35 amidatacyber730 kernel: [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
