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

I was under the impression that some G4 use this driver.

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

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.

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.

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?

am trying to take a working embedded linux system
from kernel 2.4.24 to

The working system uses u-boot 1.1.4 with linux kernel

I am using the same u-boot and I am trying to port
linux kernel 2.6.18

To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 1365 bytes --]
I meet some problems about MMU with 8260 cpu.In the function of
map_page(),the reference f is the flag to set the page present and can be
read or write.
but I find if I set the flag zero,the linux will start normal and memory
can be read and write also ,so why these happened? The MMU do not worked
normally!
wish you reply,think you.

That would certainly be ideal. Digging into the code a little deeper, it
seems like the backend's insert_memory hook should be able to adjust the
GATT table size on the fly. Not sure __get_free_pages() is expected to
succeed for dozens of pages at any given time though.

Agreed, I'll re-send the patch with the default changed to 64M.

<SNIP>
Thanks Matt (and others) for your suggestions. Matt has given me the
answers I was looking for.
Since my (2 GB) memory is within the (4 GB) addressable by a 32-bit
processor, why do I need high memory at all?
Are there performance implications on this platform from having a non
optimal low/high ratio?

I avoided this simply because I wanted to load/unload my driver (during
development), and alloc_bootmem() seemed better suited to drivers
compiled into the kernel. But I'll look again at this idea if further
problems arise with the approach above.
Thanks again,

* BogoMIPS no longer supported on PowerPC?
From: Li Yang-r58472 @ 2006-08-23 10:25 UTC (permalink / raw)
To: linuxppc-dev
I noticed a recent modification to __delay has changed from using empty
loops to reading timebase. Thus, breaks the calculation of bogomips,
and makes it terribly low. Is the bogomips no longer being supported on
powerpc arch?

What's there to be 'supported'? The only purpose of bogomips is
calibrating the delay loop, and that has changed now by using timebase,
hence bogomips no longer have a purpose. There was even a patch to
remove it from /proc/cpuinfo but I'm not sure whether that got applied
or not.

Ok, I rephrase my question as is it no longer needed? Sometimes people
may use this value as a rough estimation of CPU performance. There are
people even maintained a list of bogoMIPS of most CPUs. Maybe it is
still needed for some legacy reasons. I'm not very sure. :) At leave
we need to inform people who do look at this magic number and find it
amazingly low.

Leo
