Hi,

compile kernel with debug enabled so you will get line number from the 
crash. See what's there. Go thorough git/cvs logs and see if anybody
did anything with global mutex over sata/sr raid. Read the code. The 
possibility is you are hitting a bug which is there since raid5 was 
added to obsd, none
just tested with that amount of ssds so you are in unique position to 
hunt this bug down. Congratulations and good luck!

Hi again,

I have repeated softraid tests using six pcs of 1TB Samsung HDD 3G 
SATA drives as RAID5 and I do not face the crash issue of the OS when 
using SSDs in the RAID5.

Details of the RAID5 setting are in the attached file.

It looks like using SSD drives as RAID5 leads for some reason to the 
OpenBSD 6.8 crash. Samsung 512MB PRO 860 SSDs have 6G SATA interface 
(what is different compared to tested HDDs)


NB: Using those SSDs as RAID6 on debian Linux (buster - mdadm / 
cryptoLUKS) does not face any issues
  There are also no issues using those SSDs as RAID on FreeBSD 
(TrueNAS).

Re: Large Filesystem

2020-11-27 Thread Karel Gardas
Nice experiment, but I hope you don't do that in production nor 
somewhere where data integrity is needed.


Your SAS drives, what does their maker claim about "nonrecoverable read 
errors per bits read" for example?


As an example let's look on 6TB seagate, 10^15 read bits per one 
nonrecoverable sector read. If I'm right,
then basically you read whole drive around 20x and you get that error 
(statistically) and I guess you hope
that maker's firmware programmers have not made critical mistakes and fw 
is able to report that error
to your SAS card and that SAS card FW programmers were at least of the 
same quality and FW is able
to survive sector read error and hand your read on another drive. And 
that's just one case. What if drive

does not detect corrupted sector hence does not report it correctly?

To me this looks like too much pray for luck. With such amount of data, 
I would stay with ZFS...


Good luck!

Re: softraid(4) RAID1 tools or experimental patches for consistency checking

2020-01-13 Thread Karel Gardas



Few missing notes to this email:

- my performance testing, results and conclusion were done only on 
mechanical drives (hitachi 7k500 and wd re 500) and only with meta-data 
intensive workload. Basically tar -xf src.tar; unmount and rm -rf src; 
unmount where src.tar was src.tar of stable at that time.


- at the same time WAPBL was submitted to tech@ and IIRC it increased 
perf a lot since I've also been using limited checksum blocks caching 
(not in patch, not submitted yet) and since WAPBL log is on constant 
place RAID1c/s was more happy.


- at the time I've not had any ssd/nvme for testing. Situation may be 
different with this especially once someone think what's tolerable and 
what's not anymore w.r.t. speed.

Dear misc@,

I'm curious if anyone has any sort of tools / patches to verify the consistency 
of softraid(4) RAID1 volumes?


If one adds a new disc (i.e. chunk) to a volume with the RAID1 discipline, the 
resilvering process of softraid(4) will read data from one of the existing 
discs, and write it back to all the discs, ridding you of the artefacts that 
could potentially be used to reconstruct the flipped bits correctly.

Additionally, this resilvering process is also really slow.  Per my notes from 
a few years ago, softraid has a fixed block size of 64KB (MAXPHYS); if we're 
talking about spindle-based HDDs, they only support like 80 random IOPS at 7,2k 
RPM, half of which we gotta use for reads, half for writes; this means it'll 
take (1TB/64KB/(80/s/2)) = 4,5 days to resilver each 1TB of an average 7,2k RPM 
HDD; compare this with sequential resilvering, which will take (1TB/120MB/s) = 
2,3 hours; the reality may vary from these imprecise calculations, but these 
numbers do seem representative of the experience.

The above behaviour is defined here:

http://bxr.su/o/sys/dev/softraid_raid1.c#sr_raid1_rw

369} else {
370/* writes go on all working disks */
371chunk = i;
372scp = sd->sd_vol.sv_chunks[chunk];
373switch (scp->src_meta.scm_status) {
374case BIOC_SDONLINE:
375case BIOC_SDSCRUB:
376case BIOC_SDREBUILD:
377break;
378
379case BIOC_SDHOTSPARE: /* should never happen */
380case BIOC_SDOFFLINE:
381continue;
382
383default:
384goto bad;
385}
386}


What we could do is something like the following, to pretend that any online 
volume is not available for writes when the wu (Work Unit) we're handling is 
part of the rebuild process from http://bxr.su/o/sys/dev/softraid.c#sr_rebuild, 
mimicking the BIOC_SDOFFLINE behaviour for BIOC_SDONLINE chunks (discs) when 
the SR_WUF_REBUILD flag is set for the workunit:

switch (scp->src_meta.scm_status) {
case BIOC_SDONLINE:
+   if (wu->swu_flags & SR_WUF_REBUILD)
+   continue;   /* must be same as 
BIOC_SDOFFLINE case */
+   /* FALLTHROUGH */
case BIOC_SDSCRUB:
case BIOC_SDREBUILD:


Obviously, there's both pros and cons to such an approach; I've tested a 
variation of the above in production (not a fan weeks-long random-read/write 
rebuilds); but use this at your own risk, obviously.

...

But back to the original problem, this consistency check would have to be 
file-system-specific, because we gotta know which blocks of softraid have and 
have not been used by the filesystem, as softraid itself is 
filesystem-agnostic.  I'd imagine it'll be somewhat similar in concept to the 
fstrim(8) utility on GNU/Linux -- 
http://man7.org/linux/man-pages/man8/fstrim.8.html -- and would also open the 
door for the cron-based TRIM support as well (it would also have to know the 
softraid format itself, too).  Any pointers or hints where to get started, or 
whether anyone has worked on this in the past?

Why? To naive eyes it may look like a natural solution: e.g. before temp

no meta-data change hence speedup of operation on /tmp. In case of 
classical ffs, you will need to create file (sync meta-data update),

Software-wise, OpenBSD's UFS is probably rock solid. The only possible

NAS will consist of just one encrypted drive, regularly backed to

I'm not sure this is the best strategy.

Should I byte the bullet and build the NAS on FreeBSD taking advantage

ZFS is never overkill. Be you, I would consider to use ZFS for NAS with 
2 drives in RAID1 -- so self healing is usable if some drive or cable is 
not healthy enough. And then backup that to another ZFS box with again 2 
drive in RAID1. If you would use kind of similar OSes there with the

Looks like 9 bad sectors which can't be remapped for whatever reason. 
UDMA_CRC error count is on 0, which looks like your SATA cable is fine. 
The drive is kind of strange since it still claim Raw read error rate to 
have on 0.

I seriously doubt that. What's the output from smartctl -a for both

in SMART info as some kind of error(s). Another possibility maybe your

Look for amount of diffs published in the direction of getting it to work.
If that is zero or very close to zero, then interest is probably at the

It's not that simple. From application developer even with decades of 
experience you do not convert into kernel developer over night. Neither 
you will be able to read all the required docs and specs and make a 
brain map from them over night. It takes time. Also with all this under

less sharp with 0 patches == 0 interest judgement.

It looks like the performance issue is more complex than I have expected.
Just for the test I have installed OpenBSD 6.4 and FreeBSD 13.0 on few

I'm afraid you have installed FBSD 13.0 current which does have a lot of

for any sensible performance evaluations.
If you are curious about FBSD performance, then please install latest

Another option may be to run Xvnc inside the VM and then vnc from host

Well, with RPiX you completely missed the target I'm afriad. If I'm
correct, then whole SoC is booted on the side of video processor which
loads some blobs into it, run ThreadX OS and then boots ARMv8
bootloader on ARM core. There have been some attempt to replace ThreadX
and binary blob on RPiX, but so far IIRC unsuccessful.

So if you like to have libre hardware w/o binary blobs, then you need
to look elsewhere. I don't now situation in ARM land, but at least
RaptorCS is very vocal about advertising their POWER9 boards as truly
libre computer systems... The only issue with this is that OpenBSD does
not fly on them.

Can't install png-1.6.35 because of libraries

How to search for "hostap" in man pages.

Hello,

was looking for "hostap" or "Host AP" using man -k and apropos, but this 
somehow does not return expected results:

$ man -k hostap
hostapd(8) - Host Access Point daemon
hostapd.conf(5) - configuration file for the Host Access Point daemon

but:

$ man ral|grep hostap  
   mediaopt hostap
 hostname.if(5), hostapd(8), ifconfig(8)

$ man athn|grep hostap 
   mediaopt hostap

$ man ath|grep hostap  
   mediaopt hostap
 hostname.if(5), gpioctl(8), hostapd(8), ifconfig(8)


am I missing something or mistakenly expected man -k should return those too?

Indeed! Very nice offering, especially recent Lite. On the other hand I can't 
resist but it looks to me more and more like swan's song of POWER world. Such 
machine should be here 5 years ago at least if not right after demise of Apple 
from PowerPC world. That to just keep engineering on the platform. Now, OpenBSD 
is still supporting PPC but just in 32bit and that even on old and drying 
supply of 64bits Apple's G5s.

Foolish estimation: if you have a set of machines you would need 2 years and 
2-3 engineers to work on this platform to get it somewhere. Lot of effort to 
just support very fragile world of POWER/PowerPC. Even Freescale, err, NXP, 
err, Qualcom seems to be leaving it for ARM. Why would anyone else stay/support 
it? IBM is leaving hardware world slowly more to services so you can spent a 
lot of time and then just wake up one morning finding out that there will be no 
future POWER chips from IBM anymore -- that's depending on one vendor CPU 
supply. Fragile position.

'90s taught me that movement is done from the down to up and not from up to 
down. Intel killed all those nice workstation provides of '90s very slowly, but 
killed them at the end. It was not Sun/Digital/SGI killing intel together. 
Intel from the down of slow 486, then Pentium and then final straw was Pentium 
Pro. Sudenly PCs were faster and there was no need to stay on more expensive 
nice machines -- except perhaps for software support.

The question is, if something like that can't happen between ARM and Intel and 
then later on between RISC-V and ARM. For example Cavium's ThunderX2 looks very 
nice. In RISC-V, please see presentation of Esperanto Technologies (high-speed 
chips with a lot of various accelerators done on 7nm TSMC).

Yes, open, but do I really need to move back to Linux world? I kind of left it 
(as main workstation OS) to OpenSolaris recent years migrating from it to 
OpenBSD. Do I really need to go back to Linux mess? My bet is on ARMv8 and 
later on RISC-V. I hope both future is more bright than of IBM's hardware 
division... And life's simply too short to bet/invest a lot of time on yet 
another architecture and see its failure...

Indeed! RISC-V is making progress. For plain programmers this is probably not 
yet the right set of hardware as (1) system spec of RISC-V is not finalized yet 
(IIRC!) and (2) speed of the board CPU is probably lower than speed of Qemu 
emulation on high-speed xeon CPU.

Also, w.r.t. price, it's a bit prohibitive indeed. IIRC promise was to have 
both boards on one board and for ~$1000 but I may be mistaken on this. Anyway, 
this is just first bird and I hope there will be more comming. Especially the 
promises of Esperanto Technologies look really promising. Future is open and 
interesting!



Re: xmonad: losing keyboard after some time on 6.3 and -current.

2018-05-08 Thread Karel Gardas

Looks like the time of keyboard lost is proportional to number of key
stokes managed by xmonad. E.g quick switch between windows or
workspaces there and back is able to duplicate the issue quite quickly
(matter of 1-2 minutes).

Knowing this I've hacked my config file to absolutely minimal:


import XMonad
import System.IO
import XMonad.Util.Run (spawnPipe)
import XMonad.Hooks.DynamicLog
import XMonad.Hooks.ManageDocks

main = do
--  xmproc <- spawnPipe "/usr/local/bin/xmobar /home/karel/.xmobarrc"
  xmonad $ defaultConfig {
--manageHook = manageDocks <+> manageHook defaultConfig
--, layoutHook = avoidStruts $ layoutHook defaultConfig
--, handleEventHook = handleEventHook defaultConfig <+> docksEventHook
--, logHook = dynamicLogWithPP xmobarPP
--{ ppOutput = hPutStrLn xmproc
--, ppTitle = xmobarColor "green" "" . shorten 50
--, ppHiddenNoWindows = xmobarColor "grey" ""
--}
   {- , -} borderWidth = 5 
, normalBorderColor = "#cc"
, focusedBorderColor = "#008b00"
}


and it looks like the issue seems to be gone.

xmonad: losing keyboard after some time on 6.3 and -current.

2018-05-08 Thread Karel Gardas

Hi,

I'm looking for other xmonad users experience on OpenBSD. What I see
here is that xmonad somehow loses keyboard "connection" after some
time. I can't no longer switch between windows, workspaces, screens. I
can't no longer invoke new xterm, invoke dmenu etc. Basically it looks
like crashed, but I can still see the process running (e.g. both xmonad
and my option compiled xmonad-x86_64-openbsd are shown in ps output).
"After some time" usually means around half an hour or so. I've tested
xmonad on OpenBSD 6.3 and -current as of May 7. By xmonad I mean all
xmonad related packages provided by OpenBSD. I've also tested xmonad
head obtained from xmonad and xmonad-contrip github.com repos installed
by cabal. The experience is still the same. With xmonad I'm also using
xmobar so I provide both xmobar and xmonad config files below. When I
compiled xmonad or recompiled configuration I've used OpenBSD's
provided ghc package.

My question is: do you also see this behaviour? If so, what is your
workaround for this -- if any? If not, what's your platform/X11 details?

I'm running this on ThinkPad T500, builtin Intel graphics and OpenBSD's
provided X11 (I've not compiled myself nor apply any patches to that).
I also do have HP 27" monitor connected to laptop using display port
connection/cable. But please note the behavior of xmonad is same also
w/o connected external monitor.

Thanks!
Karel

10 GigE -T cards (Aquantia/Tehuti based cheaper models).

2018-04-16 Thread Karel Gardas


Hello,

I'm curious if anybody here is working on support for cheaper 10
GigE-T Base cards. So far it looks like Tehuti 40xx chipset cards are
cheaper than venerable Intel's X5xx and Aquantia AQ107 based are even
cheaper. I'm asking since for example Aquantia starts to appear on some
boards so man even does not need to purchase separate card to get 10
GigE on consumer or small server board (for example found that on
Asrock X470 Tachi Ultimate). My preferred Supermicro seems to support
AQ108 only (5 GigE chipset) on X11SRA...

Yes, I know Tehuti 30xx and 75xx based cards are supported by tht and
thtc drivers thanks to David Gwynne.

Thanks!
Karel

APU2/3/4 is not i-series rig. It's using AMD GX412TC SoC based on

not requiring any blob. *If* you do have your own experience with this

I'm currently routing with MikroTik 2011L and I'm not satisfied at all. I do 
have just 2 Mbit ADSL and when I tried to limit bandwith of teenagers to 
512kbps I've basically put
the board down to knees. E.g. it was running, but ping (from me!) went up to 
several seconds and whole internet was more dead then with teenagers 
downloading their stuff.
This all with up-to-date RouterOS 6.40.6 from Feb 20 2018 to patch latest 
vulnerabilities in it.

So as you have migrated from APU to MikroTik, I plan to do exactly reverse 
direction as soon as possible with OBSD on top of APU of course...

niche archs are nice, but if you do not have code of firmware to see what's its

OpenBSD-based network switch with >16 GigE ports.

2018-04-06 Thread Karel Gardas


Hello,

I'm looking to buy a new switch for house network. Ideally I'd like to setup 
everything here on OpenBSD, but I'm not lucky
to find any OpenBSD-based switch. I need just GigE ports, at least 18-20. 
Preferably fanless. 1-2U shallow depth into small rack.
I know all those Marvells, Broadcoms etc. holding majority in switch business 
with strict NDAs are not OpenBSD friendly, but
still hope something may have slipped from my sight.

Any advice appreciated.

Thanks!

IMHO it does not make any sense since (1) it was just rhetorical
question probably and (2) even if you do have set of base utils
written in Haskell, you would still need Haskell compiler/interpreter
and due to size it's probably a no go into the base anyway. And you
know the mantra: base should build base.

On the other hand, it'd also be a waste of energy probably since even
Haskell is high-productive language, you still compete with let's say
99% of utility code written in C. So what do you do if you need to do
a bug fix in this? Rewrite 100% in Haskell or just rewrite/write 1% of
bugfix in C? My bet is that if the question is not about a complete
rewrite than fixing in C is more productive.

Another point: look into the history. Systems usually stays written in
the language where they started. Unix -> C. Cobol -> Cobol. Windows ->
mix C/C++/ now also .Net. But you layer on top of those additional
functionality. Look into Unix(-like) and how it drives current world
of WWW and or mobile/phone/device industry. The core is still the
same. Unix- philosophy kernel written in C and on top of this some
additional functionality and/or web services.

So to me it looks like: use language of the target system if there is
a need to hack system functionality/bugfix, but let's use modern
language if building functionality on top of that. IMHO quite
evolutionary approach. The revolutionary approach or system written in
modern language like Haskell, I'm afraid this is not going to fly also
due to limited number of interested people not be able to go over
certain critical people-threshhold/mass. For Haskell specifically see
House, Kinetic or Hos.
https://wiki.haskell.org/Applications_and_libraries/Operating_system

The question for consideration is if microservices/unikernels approach
is not the best combination of both worlds, e.g. having something like
Mirage or HalVM based application/service running on top of OpenBSD in
its VMM, that may be interesting. Unfortunately so far both supports
IIRC just Xen.

listen on  port  -- that means listening on localhost
or its NIC, in your case all three listen will use probably your
router external LAN NIC IP address. So yes, you will need to use
different port numbers -- if you are not going to use one/two/three as
load balancing hosts for the same app. In this case you will have one
table with three hosts IPs and just one redirect.

IMHO! Also relayd beginner like you.

panices. It was few years (2 max) ago, but IIRC softdeps are not that
heavily developed in time like other parts of the kernel. From what I
remember from the analysis back than, slower the drive is, higher
chance you get panic. So I would definitely be careful in using
softdeps in exactly this situation where you do have high-latency
drive beneath the softdep mounted drive image. I had exactly the same
high-latency, VBox drive on fragmented ZFS on Solaris 11. Killer
option for softdeps. So try, but keep praying if you do that in
production...

Looks like Haskell code. if you are familiar with Haskell app built
using cabal just give it a try. Haskell itself, i.e. posgrest should
not be issue here probably. What you may hit are various possible
issues in GHC's runtime. But honestly, GHC runs very nicely on OpenBSD
so well, good luck and give it a try and report back...

No, in fact I used RAID5 purely for testing if I broke something
during my softraid hackings or not. My testing of RAID5 was intensive
offlining and rebuild with a new drive. No, I've not used 4 real
drives, but in fact just 2 real drives and on every just 2 RAID
partitions. I created array with something like -l
/dev/sd0a,/dev/sd0d,/dev/sd1a,/dev/sd1d -- or so and then randomly put
some drive/partition off-line by bioctl -O and then used the same to
rebuild by bioctl -R. If you put drive offline it'll be offline and
will not be attempted to be added again if its health status changes
(somehow and whatever it means). softraid founds its drives since it
uses (1) specific RAID partitions and (2) it saves specific metadata
to the partition. This way RAID partitions (those already part of some
array) know what array they are part of. That also means that if you
use bioctl -c on drive/partition which is already part of some array,
it'll not attempt array creation but array attachement. It's somewhat
misleading and I always felt that there should be clear "attach" and
"create" options in bioctl but so far have not come with any patches
for this.

Anyway, easy testing. Do you have some windows/linux machine with
virtualbox or do you use openbsd with vmd? If so just create virtual
openbsd environment with several drives and test what I suggest: (1)
create RAID5, (2) put one of the drives into off-line mode (3) rebuild
with another drive. Easy isn't it? If this runs fine for you, do the
same on real array...and pray/cross your finger/do whatever you do in
this case. :-)

I'm not sure, but I think that there is somewhat blury line in between
the array creation and array attach. In fact OpenBSD is using the same
command for this bioctl -c . So I see you do have two possibilities
probably:

1) IMHO more safe. If you do have enough SATA ports, then attach both
your failing drive and your new drive to the system. Boot. OpenBSD
should detect and attach RAID5 in degraded state and then you will be
able to perform your rebuild (if your failing drive is not offline,
you can use bioctl to offline it)
or
2) less safe (read completely untested and unverified by reading the
code on my side). Use bioctl -c 5 -l 
 to attach the RAID5 array including the new drive. Please do
*NOT* force this. See if bioctl complains for example about missing
metadata or if it automatically detects new drive and start rebuild.

Generally speaking I'd use (1) since I used this in the past and had
no issue with it.

but you can't do that as sd8 is already allocated and running as
crypto volume. In fact I think softraid logging is fine and your RAID5
is for whatever reason being assigned as sd7 but fails on missing
chunk. The problem may arrise from the StoreJet USB device you have
attached. If you unplug this then perhaps your RAID1 will become sd6
and your RAID5 will become sd7 and you may see it and make attempt to
rebuilt it.

For testing I would also recommend you to make sure both OSes provide
browser with the same amount of RAM (i.e. unlimit your limits in
/etc/login.conf) and I would also browse ports email list probably and
search for patch limiting amount of RAM which is allocated for firefox
javascript engine. I guess this is not the case on Linux so I would
recommend to revert this and recompile your own package and then do
another comparison.

You ask for peace but your whole post is highly explosive. Honestly
I'm still Solaris 11 user and I can assure you that on this OS
situation with browsers is even worse than on OpenBSD. In fact I'm
really surprised that chromium works on OpenBSD and you may be
surprised that I even use that from time to time over ssh tuneled X11
connection to my testing OpenBSD box. So kudos to all the brave hearts
who are working on browsers issue for OpenBSD!

Back to your topic: if you write "...that work fine in Linux...so
ridiculously slow when there are being run on OpenBSD" -- I'm afraid
for this you would need to provide some hard real benchmark numbers.
To me at least firefox run on Ubuntu 16.04 LTS/14.04 LTS, Solaris 11
and OpenBSD 6.1 more or less sucks in the same way: stupidly high
memory consumption, with a ton of tabs open the browser become less
and less responsive so the only chance is to exit it and rerun again.
So far I blame firefox's javascript compiler since chromium behaves
quite differently -- but this is only on OpenBSD/Linux so not
comparison with Solaris here...

So please provide scientific numbers of let say few page
loads/reloads/program run in of your preferred website on Linux and
OpenBSD on the exactly same hardware and do that in a verifiable way
and post here. Otherwise so far your post is only about psychology and
just your feeling...

This is entirely unfair comparison. I've just make build yesterday
tree to verify your claims and honestly what I've seen is:

1) system/core is still built with cc which means gcc 4.2.1
2) added compiler_rt is built with clang
3) added libc++ is built with clang++
4) added LLVM needed by clang is build with clang++
5) added clang is build with clang++

so what you compare is:
- OpenBSD system/core build with GCC 4.2.1 (old system)
with
- OpenBSD system/core build with GCC 4.2.1 and Clang runtime libraries
and LLVM code and Clang itself built with Clang (new system)

IMHO very unfair comparison and you should really wait till OpenBSD
system/core is build with Clang and GCC 4.2.1 is removed from the
build process. Well, do not hold your breath for that to be comparable
in speed. LLVM/Clang is C++ beast and so it takes some time to compile
but at least the comparison would be more fair...

IMHO mirror is a nice to have and if you combine this with rsync to

Not in SATA RAID business, rather prefer simple HBA + softraid/ZFS
(not on OpenBSD) and since I'm using only SR-RAID1, then board's
number of SATA connectors is usually good enough.

But using i386/openbsd on AMD E2-3200 is IMHO pure waste of precious
CPU resources you do have at your disposal. I'd recommend to go with
amd64/openbsd on this.

First version divided partition to data and checksum areas which means
RAID1 with checksums and RAID1 were compatible in a sense that if
something terribly happen in checksumming code, then you still may get
data while attaching as RAID1. Current version is using 512k data + 4k
checkksum scheme which makes it incompatible with plain RAID1.

RAID10 should be simple. RAID6 is in tree in some form. W.r.t.
HAMMER2/ZFS as a ZFS user using ZFS solely for more than 10 years
already, I'm not so keen anymore about COW due to fragmentation.
Otherwise snapshots are nice, but I'd rather snapshots to be added to
ffs in not-so-optimal form and whole fs behaving nicely than having
nice snapshots in ZFS and whole fs killed perf-wise by fragmentation.

No, ZFS does it everywhere on everything. If you do have redundancy on

Well, as a ZFS replacement I've added checksumming support into
SR-RAID1. It was really basic and as simple as possible design and
even compatible with plain SR-RAID1, but still was able to detect and
self-heal corrupted block too. So if data correctness is your mantra,
you don't need whole ZFS for it. Well, I've not submitted my code yet

IIRC the issue was caused by the fact that sensors/fan speed chip is
not able to grab temperature from drives when controller is running in
AHCI mode so putting cooler drives will not help if bug is still
there. But as I wrote this may be well fixed for months already so I'm

And once you change from RAID to AHCI please report if the noise
generated by this box increase or not. This box was known (at least in
the past) for a flaw in management firmware where if you switch to
AHCI then fans increase their speed to ridiculous rpms making the box

this always put me off and I've not seen much of those bug-reports

I've been replying based on past experience with what Tinker wrote to
this mailing list. From his posts I expected context of super-reliable
data storage on the server-class hardware. In this context non-ECC
system is simply a no go. By proper ECC support I mean system with
SECDED working at least. You are right that support for ECC in laptops
these days is pretty limited to vintage machines with UltraSPARC, some
PowerPC thinkpads (IIRC) and new machines with Xeon E3v5 from
Lenovo/Dell/HP/Fujitsu at least. OpenBSD devs are probably using what
is available to them like anybody else, don't they?

Re: ARM64:s finally on the market, and flooding it. OpenBSD support?

2016-09-22 Thread Karel Gardas
Tinker,

do not touch el-cheapo undocumented SoCs/boards, IMHO this would be
completely lost time. If you'd like to hack or buy hardware, better do
with board/SoC which is/are fully documented. And no, datasheets are
usually not good enough nor an advice to look into Linux sources...To
make it completely clear, try to get some documentation for SoC you've
listed, I would bet you will fail miserably. I've tried that in the
past and all your choices were no go. In fact the only friendly vendor
with full SoC/board developer/reference guide was Freescale/NXP of
that time. Second was NVidia with their Tegra family, but this is
again no-go due to missing GPU docs anyway...

Good luck!

And by the way, if you'd like to donate hardware, make that a bit
meaningful by offering for example ThunderX or similar kind of machine
or at least those fully documented Freescale/NXP boards which are good
enough as routers/gateways. I guess such offer would be tempting even
to OpenBSD devs and will not be thrown into the thrash easily. :-)

And if you'd like to hack on those, post your patch(es) to tech@ --
for start I guess you may get some idea from bitrig's drahn_arm64
branch and/or from FreeBSD's source tree. Generally speaking I would
guess you will need to start with in-tree LLVM and make that running

Then create another fs for just wxneeded binaries. If you don't know,
then there are 2 things which needs to be done in order to have such

 Yeah, you sure are the cool dude.

 Despite the existance of people like you, OpenBSD has been

Yes, similar functionality is in RAID1C patch I posted on tech@ in the
past. Life is too intense now so I barely work on this to update it
following Joel Sing requirements. Anyway, someday I hope to push it
