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.
| 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.
|
| Does it boot at all? | Box
|
| | Yes, it boots the installer and the installed
kernel with no problems. This is OpenSuSE-42.1, kernel 4.1.13.
|
| Processor: Intel Core i5 5250U | Box
|
| | Cores (has hyperthread, turned off) | 2
|
| | Technology | 14nm
|
| | Nominal clock speed | 1.6GHz
|
| | Turbo clock speed (1 core) | 2.7GHz
|
| | Minimum clock speed | 0.8GHz
|
| | Bogomips | 3192
|
| | Jimc's benchmark (Mb/sec) | 87185
|
| | MPEG-2 playback (ffmpeg), CPU% | 12%
|
| Graphics: Intel HD Graphics 6000 (48 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.
|
| Memory | Box
|
| | Memory parameters reported by memtest86+ and /proc/meminfo:
|
| | L1 Cache size | 32Kb
|
| | L1 Cache speed (byte/sec) | 1.60e11
|
| | L2 Cache size (per core?) | 256Kb

|
| Disc | Box
|
| |
Seagate Momentus 1 TB 5400RPM SATA 3Gb/s 8 MB
Cache 2.5-Inch Internal Notebook Hard Drive, model STBD1000100.
|
| LAN | Box
|
| | Intel Ethernet Connection I218-V,
gigabit ethernet (IEEE 802.3). e1000e driver. Our net is limited to
100Mbit/sec.
|
| Wi-fi | N.T.
|
| | Intel Wireless-AC 7265 (802.11-ac and
backward compatible with b/g/n). Not tested.
|
| Bluetooth | N.T.
|
| | Intel 8087:0a2a on USB, coordinated with
the Intel Wireless-AC 7265. Not tested. I'm actually using a Bluetooth
keyboard with an autonomous dongle that presents the keyboard and mouse
datastreams as HIDs, that can be used before the operating system boots.
|
| Audio | Box
|
| |
- Intel Broadwell-U Audio Controller, and…
- Intel Wildcat Point-LP High Definition Audio Controller
Only one is accessible; the loaded drivers are for
HD audio.
- Analog stereo codec: tested and works through the 3.5mm phone jack.
- S/PDIF on HDMI: tested and works.
- Microphone: not tested, but volume control is present.
|
| 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 b the EHCI controller also. 2 ports in front, 2 in rear.
|
| Infrared Receiver | Box
|
| | Nuvoton w836x7hg Infrared Remote
Transceiver using the nuvoton_cir driver. The sensor is in front to the
right of the headphone jack. 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 | Box
|
| | Wake on LAN | Box
|
| | Wake on realtime clock | Box
|
| | Watchdog (present but not tested) | N.T.
|
| | PXE boot (present but not tested) | 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 and to wake, in seconds:
|
| | S3 (suspend to RAM) | 2 / 6 sec
|
| | S4 (hibernate to disc) | 10 /21 sec
|
| | S5 (power off and reboot) | 9 / 73 sec
|
| | Greeter to XFCE desktop, 1st time | 11 sec
|
| | Greeter to XFCE desktop, repeat | 3 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 bug. | Fail
|
| Power consumption, not including Hauppauge HTV-950q (2W)
| OK
|
| | S3 (suspended to RAM) | 3W
|
| | Idle | 9W
|
| | Maxed out, one core | 16W
|
| | Maxed out, both cores | 20W
|
| | Playing MPEG-2 1080p video | 11W
