* Trouble on building crossover compiler for Synology 8041 PPC based NAS

Hi,
I recently bought a Synology Network Attached Server DS-106e, run using a "Linux 2. 4.22-uc-0" Kernel, under 8041 PPC, no "gcc" installed. I want to build a crosslink gcc compiler for it in another "debian 2.6 kernel" linux. I find many options in the crosslink build script on ppc, but can't find any option for 8041 PPC. So what option should I choose? And further can I put the artifacts just compiled in my Network Attached Server? So that I can compile anything directly in my NAS.
Many Thanks,
Roy

That may be due to one of my patches, and if so it's not PPC specific.
Do you get a bug report looking something like this:

Hi Tim,
Can you let us know the kernel and the u-boot version you are using
(and the origin, eg. Freescale or Denx or ...).
The issue could be in either U-Boot or Linux.
0n my MDS board with the latest U-Boot and Denx Linux kernel,
bdinfo indication 528MHz CPU, 264MHz bus frequency, then
Linux shows these same numbers in /proc/cpuinfo.
date; sleep 10; date
run on the x86 development machine at the same time
as the MDS board (well, as fast as I could move my mouse),
showed a 10s delay on both, and both finished at the
same time.
So, I think its fixed.
grep for csb_clk in the latest U-boot source shows it up
in cpu/mpc83xx/speed.c, lbiu_clk is also in there.
(lbiu_clk is the local-bus interface unit clock).
I'm not sure which clock is used for the timer time-base,
so find out the clock source of the timer the kernel
is using, and then check the clock settings in your
U-Boot versus the latest source (which you can obtain
using the git tool from Denx's repository).
grep in the arch/ppc folder of the Linux source (Denx git
version) didn't show anything for csb_clk or lbiu_clk,
so either their names are different there, or the U-Boot
source is the location of the problem setting.
I believe Kumar posted a csb_clk (or lbiu_clk) patch that fixed
a setting error ... but I can't recall if it was a U-Boot
patch or a kernel patch. I looked in the CHANGELOG for
U-Boot and I didn't see a comment related to the clock
settings (searching based on Kumar, MPC8349, or MPC83xx).
Perhaps someone reading the list has a better recollection
than I :)
Cheers
Dave

The processor is probably an *MPC8241*.
The DS101g is also an MPC8241. So this should provide you with
some useful info:

I tested this. It works, but it has no effect (pci_restore_state does not report that anything changed,
thus this means that the config space already contained the correct values).
I discovered one additional problem with leaving a device running through a sleep/resume cycle:
suspend:
ohci1394: fw-host0: SelfID received outside of bus reset sequence
resume:
ohci1394: fw-host0: SelfID is inconsistent [0x7e80773f/0x7e80773f]
The last leads to the node not being able to resume when the device is actually plugged.
Anyway, it's a separate issue, I will investigate.

David,
Could you send a system.mhs file from the EDK project you're using so I
can get a bearing on what exactly you have in the hardware? I didn't
think the LL TEMAC could be used without the DMA engine (CDMAC), which
is where the interrupts come from in the Linux/VxWorks drivers I've seen
for this core.

That is the correct distinction between "soft" and "hard". Just know
that in this case the "soft" TEMAC (whether LL TEMAC or PLB TEMAC) uses
the "hard" TEMAC, and the "hard" TEMAC by itself is not that useful.
First, thanks, your remarks have been enormously helpful.
I have successfully put together a Driver for the TEMAC currently
used in the Pico E-12.
I am still having some difficulty corresponding this TEMAC
implimentation to any of Xilinx's documentation.
It is Exactly the TEMAC supported by the Xilinx uCOSII Treck Web
Server application.
It seems to be extremely minimal. Basically a DCR interface for most
things that closely matches the GSRD documents.
and TX and RX FIFO's that I can't seem to find documented anywhere,
but I have working based on the Treck WebServer code.
I am have two remaining problems and then I am done.
The first is I am currently doing polled I/O. The transmits
happen as they are requested and the receives are picked up ona a timer
interrupt.
But I am dropping about 50% or more of the receives. I will work
that out myself eventually.
The second is that this driver will serve as the basis for a
driver in other Pico supported OS's. Some of which have no means of
doing Polled Receives.
And I can not get interrupts working. Since my hardware does nto
match anything perfectly - except that Treck Webserver application and
that does not do interrupts.
I am reading all the Xilinx TEMAC Documents and the GSRD documents
reference an IRENABLE register and an IRSTATUS register, I cobbled
something together
assuming that they were access much as the other DCR registers in
that block and I assumed the bits in IRSTATUS and IRENABLE matched the
definitions of those
in larger TEMAC implimentations. It appeared after I enabled TX and
RX complete interrupts that when I have received data available the
IRSTATUS register has the
Bit set for an Rx interrupt. All fine - except that no interrupt
actually occurs.
I can force interrupts from the PHY using the same IRQ so the IRQ is
connected correctly and programmed correctly. Other TEMAC
implimentations seem to have a GIE - Global Interrupt enable
Bit, but I do not have a clue where to look here. What I could get
out of the Xilinx Webset GSRD seems to be a Linux driver that uses the
DMA unit and that generates its own interrupts.
I don't think I have the DMA in my bit image.
Anyway any clues as to where I can find some useful docs on
Interrupt handling for the LL_TEMAC that is used by the uCOSII WebServer
application ?
Thereis a Linux driver for the LL_TEMAC that comes with GSRD, but my
group's efforts go toward the PLB_TEMAC as that is the EDK IP we want to
promote and whose drivers we'd like to see in kernel.org.
You should be able to go to http://www.xilinx.com/gsrd to get the GSRD
design, and inside of that design somewhere you'll find a Linux 2.4
driver for the LL TEMAC.

[Disclaimer: I did a fairly quick scan of your patch so I may have
misread or missed something.]
Except for not being able to extend a property (see below),
I think it does meet my needs (at least as I know them today).
However, I was hoping to keep the interfaces in the bootwrapper
similar to the ones used in the kernel. To that end, I had a
routine to find a device node and other routines to find and modify
a property within that node. I didn't notice a "finddevice" type of
function to find a device node. Would you have a problem adding one?

If we're going to allow cmdline editing in the bootwrapper, we would
need to extend the size of a property. We've never really talked about
cmdline editing in the powerpc branch but I assume that its a good
thing(tm). I know I would like to have it so, IMHO, I think we should
add it (and therefore require extending a property).

Great.

The way property modification works now is this:
p = ft_get_prop(tree, "/xen/console/interrupts", &len);
if ((NULL == p) || (len != foolen))
return;
*p = cpu_to_be32(foo);
(That does need to be hidden in a yet-to-be-written ft_set_prop().)
If necessary, it looks like it would be possible to modify ft_get_prop()
to return a pointer to the beginning of the node structure, but is it
really necessary? Do you have code that would be difficult to convert to
using
ft_set_prop(tree, "/node/prop", buf, buflen);
?

I agree, and it shouldn't be too much work. I'll take a look later this
week, if nobody else has.

Sorry about that, seems I made that change back in December. I'm
wondering if you changed something on your side that now chokes on
it, or did you just get feedup with fixing my patches by hand...
Anyway, here's a new patch with some additional fixes for slb.c.
Please let me know if you have trouble with it.

Fix some warnings when udbg is enabled.

Just a note that I will respin my patches to address all of your

to use code from a common source base. I'm going to wait until

Since you only invoke the attention on command from the debugger, how
is this better than just invoking the stop command from the probe? Is it you
are not dispatched out? That you are not at a random point in the input

Have you tried using the git protocol ("git://" instead of "http://")? Or
cloning Linus tree and then fetching Paulus tree into it?

I was just re-reading this thread and this got me thinking. I think the
current code does violate this rule if firmware has allocated more than
one MSI to the device.
In rtas_enable_msi() we ask firmware how many MSIs the device has been
given (by firmware), we then return one to the driver, but leave any
extras configured.
So this might lead to the state where the card has been configured to
use x MSIs, but we only tell the driver about 1 of them. I don't know
enough PCI to grok if that's going to be a problem.

So two things: Firewall policy prevents using git native protocol,
and it sure would be nice if we could chmod +x hooks/post-update
on that tree once and for all as that issue exists every time it
is updated.

* boot problems on pseries
From: Mark Fasheh @ 2006-08-09 1:36 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1: Type: text/plain, Size: 1595 bytes --]
Hello,
So I do most of my work on some IBM JS20 powerpc blades. They
usually run a git kernel on a stock RHEL4 distribution. The contents of
/proc/cpuinfo is:
processor : 0
cpu : PPC970, altivec supported
clock : 1600.000000MHz
revision : 2.2 (pvr 0039 0202)
processor : 1
cpu : PPC970, altivec supported
clock : 1600.000000MHz
revision : 2.2 (pvr 0039 0202)
timebase : 199837651
platform : pSeries
machine : CHRP IBM,8842-21X
Recently, I discovered that newer kernels would no longer fully boot.
There's no oops or panic message and they get through most of the kernel
initialization before simply hanging. I spent some quality time today with
git-bisect, and traced the badness down to this commit:
0ebfff1491ef85d41ddf9c633834838be144f69f is first bad commit

[POWERPC] Add new interrupt mapping core and change platforms to use it
...
A quick look through the patch didn't yield anything interesting to my eyes.
I tried booting a kernel built from the powerpc.git repository, and can
confirm that nothing in there fixes the problem. A search of this mailing
list didn't reveal anything either. Attached is my kernel .config and a cut
and paste of the boot log. Any insight would be greatly appreciated.

Pantelis,
Yes, kexec-tool can use the proposed interfaces.
kexec-tool requirements:
creating the flattened device-tree from scratch based on the first
kernel /proc/device-tree
While doing this process, should be able to
- add new properties (Ex: linux,usable-memory property under
/proc/device-tree/memory@*)
- Modify properties: size and the value of the property could be
changed(Ex: bootargs, not an issue since creating new anyway)
Thanks

* Lite5200B and ioctl(SETFLAGS) hangs in mpx5xxx_fec_open() call
From: Parav Pandit @ 2006-08-09 3:57 UTC (permalink / raw)
To: linuxppc-embedded
Hi,
Please bare through the long mail to explain my
problem.
I am working on FEC driver on Lite5200B and facing
issue when I disable the printk()s in the fec_open()
inside arch/ppc/5xxx_io.
I have commented out function call
mii_display_status() inside fec_open().
Due to this, command #ifconfig eth0 192.168.4.48 hangs
in ioctl(SETFLAGS) command.
Basically Networking stack comes up during booting,
their it opens the fec device and device gets
initialized fine. (Because system boots and doesn't
hang)
After than bash shell comes up and when I run ifconfig
eth0 192.168.4.48, it again re-initializes the device
and hangs in the set_flag()->ioctl(SETFLAGS) function
inside driver.
In kernel space, it goes like this.
Counter part of ioctl(SETFLAGS) gets called and opens
the device. (IFF_UP flag is not set).
Now fec_open() issues mii_do_cmd() for phy_>config,
phy_cmd_config, and then waits for the sequence_done
flag to get set.
But sequence_done flag is not getting set by the
interrupt handler because mii_display_config() is not
called.
Above sequence happens first time during network stack
fec_open() call but not dufing ifconfig.
Its important to note above sequence works in the
first fec_open() but fails in next.
I put the explicit delay of 10ms between
mii_do_cmd(ack_int) and mpc5xxx_fec_restart().
Current configuration is in Half duplex mode on 100M.
I really appreciate your inputs and help in debugging
to me.
Here is code snippet for your quick reference.
if (!priv->sequence_done) {
if (!priv->phy) {
printk("mpc5xxx_fec_open: PHY
not configured\n");
return -ENODEV; /* No
PHY we understand */
}
mii_do_cmd(dev, priv->phy->config);
mii_do_cmd(dev, phy_cmd_config); /*
display configuration */
/* Driver hangs here is below
mii_display_status() call is commented. */
while(!priv->sequence_done) {
schedule();
}
mii_do_cmd(dev, priv->phy->startup);
/*
* Currently, MII link interrupts are
not supported,
* so start the 100 msec timer to
monitor the link up event.
*/
init_timer(&priv->phy_timer_list);
priv->phy_timer_list.expires = jiffies
+ (100 * HZ / 1000);
priv->phy_timer_list.data = (unsigned
long)dev;
priv->phy_timer_list.function =
mdio_timer_callback;
add_timer(&priv->phy_timer_list);
if (dev->name!=NULL) {
printk("%s: Waiting for the
link to be up...\n", dev->name);
}
while (priv->link == 0) {
schedule();
}
mii_display_status(dev);
/* IF I comment this call, my driver
hangs */
if (priv->full_duplex == 0) { /* FD is
not negotiated, restart the fec in HD */
mpc5xxx_fec_restart(dev, 0);
}
Regards,
Parav Pandit
