We are aware of the issue, and working out a proper solution.

PPS input on a generic GPIO pin on Raspberry Pi.

[Peter Ankerstål]

Hi!

I have sort of exactly the same question as Erik:
http://lists.freebsd.org/pipermail/freebsd-questions/2014-July/259055.html

I have bought a https://learn.adafruit.com/adafruit-ultimate-gps and want to 
use the PPS output to discipline my clock.

But the only source of information on how PPS works in FreeBSD I could find is 
this: https://docs.freebsd.org/doc/8.0-RELEASE/usr/share/doc/ntp/pps.html and 
it clearly states the two ways to provide a PPS signal. "The PPS signal can be 
connected in either of two ways: via the data carrier detector (DCD) pin of a 
serial port or via the acknowledge (ACK) pin of a parallel port”

Since the Pi doesn’t have any DCD pin i would like to use a generic GPIO for 
this. There is a linux kernel module for this:

libssl ABI is broken in 10.3-BETA3 as compared to 10.2

[Maxim Sobolev]

Got this nice crash after switching base system from 10.2 to 10.3-beta
(without updating installing packages):

  File "/usr/local/lib/python2.7/site-packages/cffi/verifier.py", line 207,
in _load_library
return self._vengine.load_library()
  File "/usr/local/lib/python2.7/site-packages/cffi/vengine_cpy.py", line
155, in load_library
raise ffiplatform.VerificationError(error)
cffi.ffiplatform.VerificationError: importing
'/usr/local/lib/python2.7/site-packages/cryptography/_Cryptography_cffi_c57c27bax1bb7e9a6.so':
/usr/local/lib/python2.7/site-packages/cryptography/_Cryptography_cffi_c57c27bax1bb7e9a6.so:
Undefined symbol "SSLv2_client_method"

That symbol is used to be defined in libssl.so.7:

freebsd10.2> $ nm -D /usr/lib/libssl.so.7 | grep "SSLv2_client_method"
00045630 T SSLv2_client_method

freebsd10.3> $ nm -D /usr/lib/libssl.so.7 | grep "SSLv2_client_method"
freebsd10.3>

This suggests that somebody broke ABI of the library and forgot to bump the
version number. I think perhaps it's not too late to bump that now.

In that case, I would report it in Bugzilla.
(I wasn't aware of led(4) - thanks!)

That part (interpretation) is irrelevant to the OPs question - he asked for a 
way to control them, not to interpret them.

Siga seus sonhos

[news...@narcisomachado.com.br]

 

*Siga seus sonhos*
A parte de seu sonho que sinceramente expressa quem você é, é a
parte que não pode deixar de se tornar realidade.
Opte por seguir seus próprios sonhos.
Eles são exclusivamente seus por uma razão.
Você é a pessoa mais capaz de alcançá-los, e você é a pessoa que
será contemplada por eles.
Esqueça viver os sonhos dos outros.
Quando o seu objetivo é ser como outra pessoa, seu esforço para
alcançá-lo pode se transformar em frustração e desilusão.
O maior presente que você tem, para dar a si mesmo é o seu
verdadeiro eu.
Os sonhos, as metas, os objetivos e as paixões que são suas
aspirações, são expressões poderosas e exclusivas da pessoa que
você é.
Encontre e alimente-os, e eles vão energizar seus esforços.
Seja a pessoa mais eficaz que você pode ser por ser, realmente você
mesmo.
Acredite em você e siga seus sonhos.
Pense nisso.

Skylake Loader Performance 10.3-BETA3

[Will Green]

Hello,

I’ve been testing a new Skylake E3 Xeon server with 10.3-BETA3. The slow loader 
issue described on the forums https://forums.freebsd.org/threads/53511/ is 
still present. On my Supermicro X11SSH-LN4F motherboard with E3-1260L v5 it 
takes over ten minutes to get to kernel boot. After that performance seems 
normal (though I’m still testing). This issue occurs when booting the installer 
from a USB stick or when booting the installed OS over SATA. 

I understand using UEFI resolves this issue, although I only have one Skylake 
motherboard model on which to confirm this. I know this issue is unlikely to be 
fixed for 10.3 release, but I think it should be noted in the release and/or 
hardware notes. Skylake systems are going to be increasing numerous this year, 
especially now Skylake Xeons are starting to ship in volume. 

I am happy to test patches and/or current on this server if that helps. If you 
want more details on the motherboard/system I have started a post on it at 
http://buildwithbsd.org/hw/skylake_xeon_server.html

TIA
Will
