[coreboot] How does intelmetool's support for Skylake?

[Zoran Stojsavljevic]

Not sure if your strace log has anything to do with intelmetool.

I did on your strace log the following (and in *RED is possible cause* of
your problems):

[zoran at localhost projects]$ cat crash.log | grep ENOENT
access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or
directory)
access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or
directory)
access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or
directory)
access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or

access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or

open("/usr/share/misc/pci.ids.gz", O_RDONLY) = -1 ENOENT (No such file or
directory)
connect(4, {sa_family=AF_LOCAL, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(4, {sa_family=AF_LOCAL, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)

*open("/etc/systemd/hwdb/hwdb.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No

or directory)*
*open("/usr/lib/systemd/hwdb/hwdb.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No
such file or directory)*
*open("/lib/systemd/hwdb/hwdb.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No
such file or directory)*
[zoran at localhost projects]$

I guess, you have one very important missing file in your Linux
configuration, this one: */etc/systemd/hwdb/hwdb.bin... *
*/etc/udev/hwdb.bin* ?!

Here is good read:
https://www.freedesktop.org/software/systemd/man/hwdb.html
http://www.dsm.fordham.edu/cgi-bin/man-cgi.pl?topic=systemd-hwdb&ampsect=8

Have no idea who is creating this file, but you can check your Linux distro
/ tree with the following paths to find hwdb.bin:

/etc/systemd/hwdb/hwdb.bin
*/etc/udev/hwdb.bin                    <<======= In my Fedora rawhide VM
(future Fedora 26) I have here hwdb.bin =======*
/usr/lib/systemd/hwdb/hwdb.bin
/lib/systemd/hwdb/hwdb.bin

If you don't have in any, please, create one with the following link:
http://www.dsm.fordham.edu/cgi-bin/man-cgi.pl?topic=systemd-hwdb&ampsect=8

Please, let us know!
