Hi,
Has anyone tried to compile in Big Endian mode? When I compile the code in
big endian, I got the following message. Does anybody know how to solve this
problem? The assembler I'm using is "GNU assembler 2.11.90.0.27". I have no
problem compiling the code in little endian at all.
Thanks
Hanshi Li

Hi,
Has anyone tried to compile in Big Endian mode? When I compile the code in
big endian, I got the following message. Does anybody know how to solve this
problem? The assembler I'm using is "GNU assembler 2.11.90.0.27". I have no
problem compiling the code in little endian at all.
Thanks

Which time.c is this? I have seen this problem caused by mis-defined
USECS_PER_JIFFY_FRAC macro. Look at other time.c files for the right one.
Or better yet, upgrade your port to use the common time.c. See
Documantation/mips/time.README file.

Hello Jun,
The file is the common time.c from linux/arch/mips/kernel as you
can see from the third to last line of Hanshi's email. The tools
he is using are from H. J. Lu's RedHat 7.1 RPMs on the oss.sgi.com
ftp site. The file compiles just fine with the little endian version
of the same tools from the same place.
Hanshi and I will look at the USECS_PER_JIFFY_FRAC macro. Thanks for
the pointer.

It is indeed a strange problem as it only shows up in BE tools.
Some tool gurus want to look into it?
Meanwhile the following patch seems to fix it (and a couple of other

I use the BE CVS tools and haven't seen this.
How does the preprocessed code look like?

That is a kernel bug. The code only works on littl endian by accident
Here is a patch.

I assume MIPS II means you're using ll/sc in the locking code in the MySQL.
Now that the ll/sc emulation is finally fixed these instructions will
also work for ll/sc-less CPUs.

Yes. It has some Linux/mips patch. I can only guess Linux/mips looks
different than other Linux targets because of IRIX :-). See my RedHat
7.1 port for details.

Some host-PCI bridge controller may have smart endian conversion features.
Make sure you set it up correctly. The fact that DMA does not work but
polling works might also indicate the smart conversion only happens from PCI
to memory, not in the patch PCI -> CPU.
Perhaps your memory is still in LE mode even when your CPU runs in BE mode?

Since cpu_to_le32() does nothing on little endian, you can rewrite it like
#if defined(__mips__) /* XXX mips only? */
outl(cpu_to_le32(hwif->dmatable_dma), dma_base + 4); /* PRD table */
#else
outl(hwif->dmatable_dma, dma_base + 4); /* PRD table */
#endif

It seems you need either own version of outl and outw with byte swapping
or instruct your hw to do that itself (if your hw can, of course).

Yes, I depend on hardware swapping on word/dword access. It seems
many pci drivers depend on this swapping too.

Sorry, last sentence might be wrong. I doubt I have been
misunderstanding long time...
Can anybody explain me a PCI driver's policy of endianness? Should we
use cpu_to_le32 with outl/writel? Should we use cpu_to_le32 to write
32bit data to DMA area?
Thank you.

The PCI bus is little-endian.
All accesses should be done using one of
- {read,write}[bwlq]: PCI memory space
- {in,out}[bwl]: PCI (and ISA) I/O space
- isa_{read,write}[bwl]: ISA memory space
The functions above should take care of endian conversion.

It depens on device and board. Most drivers assume PCI is little-endian,
but rely on outl implementation in byte swapping policy.
> Should we use cpu_to_le32 with outl/writel?
If you can't instruct hw to perform byte-swapping for PCI IO, you have
to add cpu_to_le32, it's clear. For writel, i.e. PCI MEM the situation
is a bit subtle. The problem is your videocard, that may or may not
support byte swapping. So, in order to suport videocards that aren't
able to swap bytes, you have to setup PCI MEM in big-endian mode.
Look, for example, at the tulip driver, it swaps bytes for DMA and
doesn't do it for register access.
> Should we use cpu_to_le32 to write 32bit data to DMA area?
DMA data is stream of bytes. I would treat a device/board as broken, if
it would need byte swapping for DMA data.

Gleb.

Thanks Atsushi San, the patch did help. The partition check can pass now.
But my boot (such as: usb, ethernet, etc.) could not continue after solving
the IDE problem.
Could anybody give me a hint?

Sorry, my patch is not correct. You can configure your PCI controller
to swap dword (if your hw have this function), or you can use
CONFIG_SWAP_IO_SPACE.
If your hardware have not this function AND you want to swap entire
I/O access (for example, do swap for PCI, not for other area), you may
have to create your own version of outl/outw etc. (This is my
case...)

You should actually just be able to delete the #if stuff. On an LE machine
cpu_to_le32() is a null operation

You should actually just be able to delete the #if stuff. On an LE machine
cpu_to_le32() is a null operation

Hi there.
Is there anybody here who knows how to configure MySQL for use both with
a webpage and with applications running on computers elsewhere on the
Internet?
If so, would you mind giving me a one-on-one session to configure it
here, and also to set up a web page to look up entries in it and display
the results?
Best wishes from Riley.
