Cupertino test ring problem?

Cupertino test ring problem?

[James Bottomley]

The gateway machines to cupertino (gsyfrf11/10) have been inaccessible
for most of last week.  Can we get someone local to give them a poke and
see what's up with them?

Dave Anglin asked me about it during OLS.  I suggested he poke Rick
Jones ...

That explains that mild ache in my side :)

The Cupertino test ring got moved last week from one machine room to 
another. This also included netperf.org and ftp.cup.hp.com. Shutdown was 
about 1600 Pacific time on the 23rd, and power was restored to the racks 
by about that time on Thursday.  I brought-up netperf.org, 
ftp.cup.hp.com and they talked fine and dandy on the network, so I 
simply powered-on the lp1000r gateway and ass-u-me-d it would work as 
well.  I guess it didn't :(  and I will try to take a look at them today.

A couple of the rx2600's were not powered-up, so I've powered them up. 
One of the rp34xx's does not seem "happy" and will need further 
diagnosis.  If there are other things still "not right" with the ring, 
please feel free to let me know the specifics.

gsyprf11 and gsyprf10 are still not responding to pings ... could the IP
routings have changed or something?

Well, the IP's have remained the same, but the systems are physically in 
a different building.  Both netperf.org and ftp.cup.hp.com have moved 
from the same starting point to the same end-point.  If folks cannot 
ping them or cannot get to port 22 on those then there is still 
something amis in the network.  Otherwise there is still something amis 
with gsyprf[3|10|11].

gsyprf10 at least is one of the ia64 boxes.  Helpfully it identifies
itself as lp1000 or something at the login prompt.  gsyprf11 is a PA
A500 type box.  It should identify as gsyprf11 at the login prompt.  We
only need one up and running to begin diagnosing as we should be able to
then get to other remote consoles.

gsyprf10 is an x86 machine (HP lp1000r netserver).

I'll check with Rick tomorrow to see when I can drop by to help resurrect
them.

I expected gsyprf10 to auto reboot on it's own.
I'll change gsyprf11 and gsyprf3 to also autoboot since I don't think they
do at the moment.

I can confirm that gsyperf3 was/is not set to autoboot.  I can also 
state that it cannot successfully boot.  During POST it spits-out FRU 
problem messages and during OS boot boatloads of Segmentation Fault 
output while it tries to boot, and end-up in busybox.

I'm not sure that gsyprf11 (pa) is connected to the external net.

I tried swapping the cables on gsyprf10 (the lp1000r)  I have to see if 
I can find the old monitor and keyboard to see what its boot state 
happens to be.

Grant - wrt times, I'm here all week, from about 0930 to about 0330 each 
day.  I'd be around later but this week I'm playing single-parent :)

Debian kernel didn't find it's root disk...older kernel I built booted fine.
It's up and I restored the default to a kernel that boots. I can test
other debian kernels on other machines and update gsyprf3 once those
are proven to work.

Rick and I swapped gsyprf3 (1.5Ghz proto CPUs and pre-production mother
board and case) for a production unit (1.3 Ghz CPUs and 8GB of RAM).

> I'm not sure that gsyprf11 (pa) is connected to the external net.

It wasn't and the default debian kernel didn't boot either.
I've set the default kernel to jda's 2.6.22.19 patched kernel.

again, bad 2.6.24 debian kernel. Rebooting to older (2.6.21) debian
kernel worked. Updated the machine but not willing to try a newer
kernel on this box unless I'm sitting in front of it with a console.

thanks for helping this morning.
Getting the three key systems up was critical.
I can continue to muck with the rest.

Is there a source tarball of that, or a list of applied patches? I
would very much like to use that "homebrew" kernel on my cluster as
well, until newer kernels are proven reliable enough...

I built a tar ball, linux-2.6.22.19-jda.tar.gz.  It is in my home directory
on gsyprf11.  The source is also there.  The most important patch is
compat_sys_getdents.d from Kyle.  The base is linux-2.6.22.19.tar.bz2
from kernel.org.  The .config file was derived from some earlier config
file on this machine (can't remember which).

Thanks a lot, I'll fetch that later on!

X won't start with VisEG and 2.6.22.19

I should mention that I've had a problem with starting X with lenny
and 2.6.22.  This has been a problem for sometime.  I've tried simplifying
the xorg.conf file and adding the mode helper to the kernel, but I
haven't found the magic incantation that works.

Re: X won't start with VisEG and 2.6.22.19

[Guy Martin]

Hi Dave,

This has been introduced in latest Xorg. When it modify the fb device,
Xorg query the kernel again to make sure changes are the expected ones.
Apparently, stifb doesn't return what it was expecting.

You'll find the Xorg code in hw/xfree86/fbdevhw/fbdevhw.c,
fbdevHWSetMode().


Cheers,
  Guy

Guy, thanks for the hint, and yes I see this problem as well.

The problem is really caused by hw/xfree86/fbdevhw/fbdevhw.c.

The driver sets a video mode and then checks if the syscall modified the 
parameters with the function fbdev_modes_equal():

--snip--
/* static*/ Bool
fbdev_modes_equal(struct fb_var_screeninfo *set, struct 
fb_var_screeninfo *req)
{
         return (set->xres_virtual >= req->xres_virtual &&
                 set->yres_virtual >= req->yres_virtual &&
                 set->bits_per_pixel == req->bits_per_pixel &&
                 set->red.length == req->red.length &&
                 set->green.length == req->green.length &&
                 set->blue.length == req->blue.length &&
                 set->xres == req->xres && set->yres == req->yres &&
                 set->pixclock == req->pixclock &&
                 set->right_margin == req->right_margin &&
                 set->hsync_len == req->hsync_len &&
                 set->left_margin == req->left_margin &&
                 set->lower_margin == req->lower_margin &&
                 set->vsync_len == req->vsync_len &&
                 set->upper_margin == req->upper_margin &&
                 set->sync == req->sync && set->vmode == req->vmode);
}
--snip--

As you can see, the main video parameters are OK, while the 
monitor/modeline values (pixclock, left_margin, right_margin, 
upper_margin, lower_margin, hsync_len, vsync_len, sync and vmode)
were changed to zero.

Interestingly the stifb driver does not touch those values at all. 
Everything is done inside the main fbmem.c core driver, so it seems it 
could become a generic problem for other framebuffer drivers as well.

I don't see a reason, why a framebuffer driver should care about 
modelines (except for resolution and bpp) at all. OK, on a i386 with 
e.g. vgafb you might be able to change the resolution, but on the hppa 
architecture with the stifb driver this is not the case. It's a fixed 
resolution with (often) a fixed frequency monitor which can't be changed 
at runtime from inside the OS.

Any ideas?
Should I open a debian bug report?
Maybe the fbdev_modes_equal() function should just ignore any changes to 
  the timings?

The maintainers for the fbdevhw.c and fbmem.c files need to be contacted
to determine what fbmem.c is allowed to change and what what fbdev_modes_equal
should be checking.  It's possible Debian is messing with the code as well,
so a Debian bug report wouldn't hurt.

Thanks for looking into this.

The is the kernel's implementation:

int fb_mode_is_equal(const struct fb_videomode *mode1,
                     const struct fb_videomode *mode2)
{
     return (mode1->xres         == mode2->xres &&
