Intel NUC6CAYH
Subsystem Checkout

Jim Carter, 2018-01-16

This is for the Intel NUC6CAYH that became Jacinth: serno G6AY 7490 03GD, MAC address f4:4d:30:69:e2:1c . When the new machine was received, I checked out these features. In summary, every one of the features that the machine was supposed to have, performed with no hassle out of the box, with one exception.

Legend

Box Worked out of the box.
Conf It needed editing a configuration file or running a setup GUI.
Add-On Needed additional or patched software: download it; follow instructions to compile and/or install it; it works.
Fiddle As with Add-On, but it required some workarounds in the procedure, which might seem minor to an experienced user but which might prevent a newbie from making it work.
Hack So you call yourself a guru? This one will challenge your skills. But this guru eventually got it working.
Fail I wasn't able to get this one to work, at least so far.
N.T. Not tested.
* A prerequisite did not qualify for the Box or Conf rating, but once that was set up, the listed component worked with no further hassle.

Checklist of Features

Does it boot at all? Box
 Yes, it boots the installed kernel with no problems. This is OpenSuSE Tumbleweed, kernel 4.14.12.
Processor: Intel Celeron J3455 Box
  Cores 4
  Technology 14nm
  Nominal clock speed 1.5GHz
  Turbo clock speed (1 core) 2.3GHz
  Minimum clock speed 0.8GHz
  Bogomips 2995
  Jimc's benchmark (SHA-512, Mb/sec), per core 101.7
  Playing MPEG-4 1080p video (VLC) 10.3%
Graphics: Intel HD Graphics 500 (12 execution units) Box
  Using the HDMI port, with a 1920x1080px display (1080p), the machine can perform MPEG-2 and H.264 encoded media with no problems: way more than enough CPU power and no dropped frames. I'm assuming without proof that the GPU is doing the decoding. But see below about the sound.
Memory Box
  Memory parameters reported by memtest86+ and /proc/meminfo:
  L1 Cache size 24K
  L1 Cache speed (byte/sec) 3.74e10
  L2 Cache size (per core?) 1024K
  L2 Cache speed (byte/sec) 1.97e10
  L3 Cache size None
  L3 Cache speed (byte/sec) --
  RAM on this machine 2 x 4Gb
  Main RAM speed (byte/sec) 5.63e9
  Video RAM reservation (estimated) 256Mb
  Sockets for RAM 2
  Installable memory limit (total) 8Gb
Disc Box
  Seagate Barracuda 500 GB 7200RPM SATA 6Gb/s 128 MB Cache 2.5-Inch Internal Notebook Hard Drive, model ST500LM030
LAN Box
  Realtek RTL8111/8168/8411 gigabit ethernet (IEEE 802.3), r8169 driver. Our net is limited to 100Mbit/sec.
Wi-fi N.T.
  Intel Wireless-AC 3168 (802.11-ac and backward compatible with b/g/n), iwlwifi driver. Not tested.
Bluetooth N.T.
  Intel 8087:0aa7 on USB, part of the Intel Wireless-AC 3168. Not tested.
Audio
  Intel Corporation Celeron N3350/Pentium N4200/Atom E3900 Series Audio Cluster
  Driver: snd_hda_intel Box
  Analog stereo codec: tested and works through the 3.5mm phone jack. But there's a quirk: when the playback program finishes and closes the output device it appears to disconnect from its output, and the amplifier receives 60Hz hum. Quirk
  S/PDIF on HDMI: Unable to test. Beware, there is buggy firmware in the internal Display Port to HDMI converter that prevents sound on Linux, and the patch requires Windows. Fail
  Microphone: not tested, but volume control is present. N.T.
USB Ports Box
  One bus with controllers for USB-2.0 (EHCI, 480Mbit/sec) and USB-3.0 (XHCI, 5Gbit/sec); standard devices (12Mbit/sec) are handled by the EHCI controller also. All external ports do USB-3.0; 2 ports in front (one for charging), 2 in rear.
Infrared Receiver Box
  ITE 8708 Infrared Remote Transceiver using the ite_cir driver. The sensor is to the left of the USB ports. The acronym CIR is used in Intel literature to describe this device. Used with a Philips ElectroHome remote control, it loads the rc_rc6_mce protocol handler and delivers keysyms acceptable to MythTV. See my writeup on configuring the remote control.
Special Features
  Auto boot when power returns (turn on in BIOS) Conf
  Wake on LAN from S3 or S5 Box
  Wake on realtime clock from S3 or S5 Box
  Wake on LAN or RTC from S4 (turn on in BIOS) Conf
  Watchdog (present but not tested) N.T.
  PXE boot (attempts PXE, but server lacks boot file) N.T.
Suspend and Wake Box
  By default, the machine wakes or boots on all of USB, realtime clock, and LAN. USB wakeup can be turned off in the BIOS. Wake on infrared can be turned on. Times to suspend / wake, in seconds:
  S3 (suspend to RAM) 2/3 sec
  S4 (hibernate to disc) 20/41 sec
  S5 (power off and reboot) 10/118 sec
  Onboard devices including graphics can suspend and wake successfully.
  The Hauppauge HTV-950q and 1950 TV capture devices (USB) do not suspend cleanly to S3 or S4 due to a driver or firmware bug. Fail
Power consumption, not including Hauppauge HTV-950q (2W) OK
  S5, S4 (power off, hibernate) 0W
  Booting up 9-12W
  S3 (suspended to RAM) 3W
  Idle 8W
  Maxed out, one core 11W
  Maxed out, 4 cores 16W
  Playing MPEG-4 1080p video (VLC) 11W
