The other version that was posted had support for modifying an
existing flat tree, which I need for the wrapper code for prep. Are
those "Matt's changes"? Are you thinking of adding that capability to
your version?

Tsi108 serial port has some difference from the standard 8250 port.
I add UPIO_TSI in general 8250 serial driver to handle IIR and IER
register=20
in serial_in and serial_out.
(1) the reason to rewrite serial_in:
TSI108 rev Z1 version ERRATA. Reading the UART's Interrupt
Identification Register (IIR) clears the Transmit Holding Register
Empty (THRE) and Transmit buffer Empty (TEMP) interrupts even if
they
are not enabled in the Interrupt Enable Register (IER). This leads
to
loss of the interrupts. Interrupts are not cleared when reading
UART
registers as 32-bit word.
(2) the reason to rewrite serial_out:
Check for UART_IER_UUE bit in the autoconfig routine. This section
of autoconfig is excluded for Tsi108/109 because bits 7 and 6 are
reserved for internal use. They are R/W bits. In addition to
incorrect identification, changing these bits (from 00) will make
Tsi108/109 UART non-functional.
I need to pass UPIO_TSI flag to the 8250 driver when the tsi108 bridge
serial port is used.

Nope. Only G5s. I had plans to use the windfarm infrastructure to move
over some of the G4 thermal control code as well but never had the time
to do so.

It seems that there are some workarounds for TSI "features" in
drivers/serial/8250.c that this will invoke.

Why windfarm? It doesn't do anything useful on 32-bit machines, not

Maybe, I'm missing something, but why do we need this? Why doesn't
iotype == UPIO_MEM work for the TSI?

Same comment as the other patch, it looks like it got wrapped by your
mailer. Also make sure you don't add trailing whitespaces (if you quilt,
the latest version detects them and has an option to fix them up for
you).
Appart from that, what the patch does looks good.

Ben.

Yes, and historically baud 0 meant 'hang up modem'.

More precise, IIRC, it should have said:
"Minutes after running gscanbus, that is a few minutes after sending
the quoted message: still no /dev/sda"
Sorry for the overhead

* [PATCH] powepc: Fix BootX booting with an initrd
From: Benjamin Herrenschmidt @ 2006-08-23 1:45 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev list
The bootx_init.c trampoline didn't properly add the ramdisk to the
"reserve map" (list of reserved areas of memory), thus causing all sorts
of failures when using BootX with an initrd. Also fixes a possible
problem if the ramdisk is located before the device-tree passed by
BootX.

* [PATCH] fix gettimeofday inaccuracies
From: Nathan Lynch @ 2006-08-23 1:36 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
There are two problems in the powerpc gettimeofday code which can
cause incorrect results to be returned.
The first is that there is a race between do_gettimeofday and the
timer interrupt:
1. do_gettimeofday does get_tb()
2. decrementer exception on boot cpu which runs timer_recalc_offset,
which also samples the timebase and updates the do_gtod structure
with a greater timebase value.
3. do_gettimeofday calls __do_gettimeofday, which leads to the
negative result from tb_val - temp_varp->tb_orig_stamp.
The second is caused by taking the boot cpu offline, which can cause
the value of tb_last_jiffy to be increased past the currently
available timebase, causing the same underflow as above.

We are still comparing these two approaches IPoIB performance under
different configurations. Hopefully the performance work can be done soon.
So we can have some data to share.

Some tests on the Alubook:
I compiled a fresh git kernel now with verbose ieee logging turned on.
$ uname -r
2.6.18-rc4-ieeeverbose-gef7d1b24-dirty
$ zgrep 4_VERBOS /proc/config.gz
CONFIG_IEEE1394_VERBOSEDEBUG=y
Before starting the FW disk I removed all ieee drivers I thought could
be relevant, with this little script:
-------------------------
#!/bin/sh -x
/bin/sh -n /home/shorty/scripts/scsi.stop.sh; \
rmmod raw1394; \
rmmod eth1394;
rmmod ohci1394; \
rmmod sbp2; \
rmmod ieee1394
---------------------------------------
Then, with the FW disk connected to the alubook, but *not yet* powered
on by the latter via a switch at the enclosure which obviously, when
switched on, feeds the current to the firewire disk, thus switching it on:
-----------------------------------
#!/bin/sh -x
/bin/sh -n /home/shorty/scripts/scsi.start.sh ; \
modprobe ieee1394 disable_irm=0; \
sleep 2; \
modprobe ohci1394; \
sleep 2; \
modprobe sbp2; \
sleep 2; \
modprobe raw1394; \
sleep 2
chown root.shorty /dev/raw1394
sleep 4; \
ls /dev/sda
-------------------------------
Only after running the latter script, I switch on the FW disk. The log
for these moments covering about 60 seconds is here:
wolfgangpfeiffer.com/kern.log.when.fw.disk.is.switched.on.txt
Then, some time later on with no /dev/sda available, I run gscanbus,
forcing a bus reset. The log, again covering about 60 seconds is here:
wolfgangpfeiffer.com/kern.log.with.gscanbus.after.failed.fw.connection.txt

Please, if you think it might help, let me know if want to change the
scripts to load the ieee drivers ... (Note the disable_irm=0 in one of
the scripts above .. )
Til then

* MontaVista 2.4.30 kernel support for bus error status registers on Xilinx VirtexIIPro?
From: Keith J Outwater @ 2006-08-22 23:04 UTC (permalink / raw)
To: linuxppc-embedded
Hello,
I am running a 2.4.30 kernel rsynced from Monta Vista on a Xilinx
VirtexIIPro FPGA.
My design includes a PLB2OPB (Processor Local Bus to On chip Peripheral
Bus) bridge that is
capable of generating a bus error interrupt when an OPM slave device
asserts it's bus error
signal. The PLB2OPB bridge also has a set of "bus error status and
address registers"
that are capable of capturing information regarding the type of error that
occurred.
Has anyone implemented support for this functionality in a 2.4.x kernel
running on
VirtexIIPro FPGAs?
Thanks!
Keith

I havent seen that sort of error, maybe a bad burn.

You can try to boot the inst32 file via the network. Make sure to fix
the ARP entry for the H50 on the tftp server, like 'arp -s 1.2.3.4 MAC'
yaboot.ibm can also be used. Rename yaboot.cnf to yaboot.conf so yaboot
will be able to download it.

No, you can't do that, the kernel headers are not generally
working in user space, recent kernel versions protect you
from doing this.
If you don't have a library providing you with atomic operations,
you can copy the inline functions from the kernel, which will
work fine, but require that your app is GPL licensed.
