Re: [9fans] Installation woes
For what its worth.

[9fans] offtopic: snarf from ITS
I finally got ITS running on my simh plan9 port. I discovered that one of the DDT command from ITS is snarf :SNARF job if the current job (say, FOO) has an inferior named job, this command takes job away from FOO and then does :JOB job . Thus, job becomes a direct inferior of the DDT executing this command, instead of an indirect inferior. FOO is not told that its inferior is gone, but if it is a DDT it will recover after an $J is done to it. This command is most useful when done to a HACTRO that got detached because of a top- level interrupt, but whose inferiors are valuable. (The thing to do is HACTRO$J :SNARF TECO , etc.)

Re: [9fans] ape/socket again non-blocking command succeeds but still blocks
I need to apologize, my sample code made things more confusing.
In unix the code I posted would have raised an error because
newsockfs=accept()...would not block and just pass through. The idea
is you can loop through accept() and multiplex multiple inputs.
but in plan9/ape it works just as how you shown regardless of the
fcntl non-block command. so I will not be able to loop through several
sockets because it would block.

The KS10 uses the PDP-11 Unibus for its I/O, via adapters. While
nominally four adapters are supported, in practice only 1 and 3
are implemented. The disks are placed on adapter 1, the rest of
the I/O devices on adapter 3.
In theory, we should maintain completely separate Unibuses, with
distinct PI systems. In practice, this simulator has so few devices
that we can get away with a single PI system, masking for which
devices are on adapter 1, and which on adapter 3. The Unibus
implementation is modeled on the Qbus in the PDP-11 simulator and
is described there.
The I/O subsystem is programmed by I/O instructions which create
Unibus operations (read, read pause, write, write byte). DMA is
the responsibility of the I/O device simulators, which also implement
Unibus to physical memory mapping.
The priority interrupt subsystem (and other privileged functions)
is programmed by I/O instructions with internal devices codes
(opcodes 700-702). These are dispatched here, although many are
handled in the memory management unit or elsewhere.
The ITS instructions are significantly different from the TOPS-10/20
instructions. They do not use the extended address calculation but
instead provide instruction variants (Q for Unibus adapter 1, I for
Unibus adapter 3) which insert the Unibus adapter number into the
effective address.

I had some success yesterday, but more so with Erik's 9atom ISO than the one from the labs. It handled the VirtualBox disk emulation much better. Anyway, I ended up with a very similar configuration, but with the ISO on the secondary master and the fossil FS on the primary master (though I think it also worked the other way). I tried all three of the disk controller settings PIIX3, PIIX4, and ICH6, but none worked with the Labs' image. It looks like I used the ICH6 setting with 9atom. I ended up using the PIIX3 chipset, but mostly because that's what it was left on when I switched to 9atom. I expect it would work with PIIX4 as well--not sure about the ICH9. Toward the end of the day, though, I also got a VirtualBox instance to boot off of a real Plan9 file server as a diskless terminal...using IL to Ken's FS even :) This was with the Intel PRO/1000 MT Server in a bridged config. This also required the VirtualBox extensions to allow PXE booting from the Intel cards. As always, your mileage may vary... I spent a few hours and investigated virtualbox 4.0 here is a summary latest official plan9 iso installed perfectly no network support. latest 9atom iso installed perfectly however after reboot it fails with the following errors MBR...PBS1...Bad Format or I/O error Press a key to reboot... reinstalling 9atom over the plan9.iso installation fixed everything, it's bootable and with netwrok support. thanks all

[9fans] simh old computer simulator
I have ported simh 3.8-1 to plan9. It currently has the following issues 1. Since I am on christmas break, i dont have access to my cpu server. all testing was done on 9vx 2. 9vx seems to do wierd stuff if you keep the cpu load at 100% for too long, so i had to implement a simple idling routine. set throttle also works but i preferred having a dynamic load change.( i'm using rons 9vx bitbucket stuff by the way.) 3. simh had it's own idling, but it looked like I needed to get into the code deeper than I thought is necessary. 4. compiling the pdp10 seems to kill 9vx. compiling vax still had a few gnu-ish preprocessor directives that prevents it from being compiled. 5. I dont know much about socket programming so i am not sure if it's working. When I try to run it with telnet it cannot open up a port. I will proabably send a separate email asking about ape sockets later. to build gunzip simh-p9.tgz tar x simh-p9.tar cd simh-p9 plan9/build this only compiles the ones i care about excluding pdp10 and vax plan9/build_all tries to build everything. http://plan9.bell-labs.com/sources/contrib/fernan/simh-p9.tgz

I understand, what confused me was that ramfs is not using File/createfile. So even though ramfs could have taken advantage of the createfile tools it didn't. why?

Re: [9fans] zero length arrays in gcc
Hi all both option did not solve my lost pointer problem.

[9fans] zero length arrays in gcc
Hi all
nhc98 uses a few of
static unsigned startLabel[]={};
which is a zero length array. It appears that it uses this as
reference to calculate the correct pointer for a bytecode.
pcc does not allow this since zero lenth array is another gcc
extension. I tried declaring it as
static unsigned startLabel[];
The resulting bytecode can then be compiled however it will only
crash. I traced it a pointer that tries to read an unallocated section
in memory.
Is it possible emulate zero pointer in pcc??

The initializers to some things need to be constants.
In your case, it appears that either CAPTAG or useLabel (or both)
have ended up not being #define'd. Probably the header they are
#define'd in is not being #include'd (you don't show it above,
but then you don't show enough of your code to even reproduce it).
On a relate note, you can see the results of preprocessing
from pcc by using the -E and/or -P options, that way you
can see whether the macro ended up getting substituted
and what it was substituted to -- or not in your case.
Some compilers also have options which will emit the trail of
files #include'd but I don't see that option for pcc.
gcc happily compiles a definition like
#define CT_v249 ((void*)startLabel+464)
is it valid just to add to make the porting non-destructive?

What utterances do I need to enter in order to rebuild the kernel as it appears on the 9atom cd? so, while i recommend that the contrib packages be used instead, after some thought and a few hrs of quality time removing half-finished bits, i packaged up the source used to build the 9atom kernels. ftp://ftp.quanstro.net/other/kernel.mkfs.bz2 to extract to the current directory bunzip2 kernel.mkfs.bz2 | disk/mext -d . if anyone objects to this being out there, i'll just remove it. off the top of my head, this kernel has the following little bits in addition to tje contrib packages: - jumbo frames, used with aoe (#l0/ether0/mtu), - /dev/cputemp on modern amd and intel processors, - kbd led control, repluggable ps/2 mice, cec console server, - console on non-onboard serial lines, turning serial console on/off, - pat, - /dev/nomp (mp irqs off), and /dev/mpirq (irqs turned on), the kernel you build will *still* be a little different than mine because of some changes to libauthsrv i made. these differences are in the patch readnvram that allow nvram to be on any sd device. this is particularly useful for ahci laptops that may have sdE2 (cdrom) and sdE3 (hd). while they could have been added to the big array in libauthsrv.c/nvram, i found it hard to manage.

Hi Corey
I recently used your guide to setup a cpu server. I have to say that
it was a lot clearer than the wiki version. I did remember needing to
uncomment the lines below in cpurc based on my old install.
# if(! test -e /rc/bin/service.auth/il566){

# mv /rc/bin/service/tcp567 /rc/bin/service/!tcp567
# }
I am not sure your guide needs to be updated to do that instead of just
step 5.
term% mv /rc/bin/service.auth/authsrv.tcp567 /rc/bin/service.auth/tcp567
I am not sure of the advantage of doing it either way.

[9fans] when to use vac -q -d old.vac instead of simply vac -d old.vac
Hi The p9p vac discussion made me re-think the way I use vac. man vac -qIncrease the performance of the -a or -d options by detecting unchanged files based on a match of the files name and other meta data, rather than examining the contents of the files Why is -q not a default? Is there a reliability concern with that option? I am currently doing an hourly backup using vac -d old_date-time.vac -f new_date-time.vac /home which gives me a collection files with a date-time.vac filename. I am thinking I should just use vac -a main.vac /home to switch to this method I only need to rename latest date-time.vac to main.vac and delete the other ones, right? fernan -- http://www.fernski.com

Re: [9fans] plan9 for calculations
On Sat, Mar 28, 2009 at 5:31 AM, Rudolf Sykora rudolf.syk...@gmail.com wrote: Hello everybody, I noticed there are some thoughts about using plan9 on supercomputers. For me supercomputers are usually used to do some heavy calculations. And this leads me to a question. What software is then used for programming these calculations? (I mean e.g. linear algebra, i.e. matrix, calculations.) Where can one read about that? More, it also leads me to a (perhaps) simpler question. What is the situations with ordinary machines? Untill now I have used several libraries in linux, all of them somehow based on lapack. I used C language (c-lapack), python (numpy), and now I do some programming in Fortran (Intel MKL). From my experience I would say: writing programs in C is a nightmare (for me next to no-go again), using python with numpy is a breeze, using Fortran (95) is sort of fine. C and Fortran run faster than python, but the factor, when I played with it, surprised me to be sth. like 3x (expecting a worse result). Now I've been thinking, If I were to write sth. in plan9, what would be the way to try? Recently I heard about eigen2 library, which seems to be nice (high performance, few dependencies), but for C++... Thank you for any suggestion Ruda PS.: It could be that plan9, being more a os-research system than anything else, is simply no suitable for such a use (there are no plotting libraries, other utilities). Perhaps it's not a good idea at all to try to use plan9 like that because it would be more work than anything. Maybe using linux for such things with all its tools is just ok. If you share this idea, just say it too, please. Its not supercomputer level, but I have a sparse matrix solver in my contrib. I use it along with haskell as simple replacement for octave. It is mostly a collection of scripts right I am hoping to consolidate it later as a single package. I also cannot give you a alot of example mainly because it will translate to an actual project I did for my day job although those were done on mathcad I did notice that for some plotting needs simply piping it plot command is adequate instead of bloating my tools with plot routines. fernan -- http://www.fernski.com
[9fans] looking for opinions on Interprocess communication
Hi all I was wondering if you guys have an opinion on the following data communication methods. The data are mostly a bunch of binary where program1 is asking program2 to do something with the data and send the results back to program1. The data is currently very small less than 1Kbyte, but I am not sure if it will grow later. I am also not sure how much time program2 needs to send a response. method 1 - This simply uses plumber and it greatly simplifies both program1 and program2 program1 -- file IO - plumber - program2 - file IO - plumber - program1 method 2 - In this scheme program2 is a server, mounted on the file system. The client does not need to know 9p program1 - file IO - server/progam2 - fileIO - program1 method 3 - program2 is still a server but, the client uses 9p to communicate with program2 program1 - 9p - server/program2 - 9p - program1 I hope that made some sense to somebody. regards fernan -- http://www.fernski.com

pe string Use string as the style for drawing lines. The

long, dotd[ashed], cdash, ddash

Sorry Erik I dont particuarly understand your reply
I am guessing that it's referring to pe working for lines only.
but doing this will also produce a solid line instead of what I
thought it should produce a dashed line

the pe command seems to call pen.c in libplot

not sure where USED(s); is implemented.

The Plan 9 threaded programs manage their own stacks, making it impossible for the user-space simulations to find their thread-local state. Most Linux distributions switched to real threads (i.e., dropped LinuxThreads in favor of NPTL) around the time they switched to the 2.6 kernel. FreeBSD switched in the FreeBSD 5 release.
