The problem is that it will then be part of the linear mapping, which
means you'll end up with a double cacheable & non-cacheable mapping for
that memory, this is not nice ... it might work as long as we stick to
having G bit set for the whole linear mapping but it's going to come
back and bite.
I still think you should look closely whether it could be carved out
of the end of memory... even if that involves changing application
code.
Now, if you aren't afraid of cache paradox caused by the linear
mapping, then carve it out of the LMB wherever it is rather than
lmb_reserve() it. That would probably work.

Well, actually the other functions like oprofile_add_trace are using the
&__get_cpu_var(cpu_buffer) construct.

Here they are:
/home/jroth/kernel/spufs/arch/powerpc/oprofile/../../../drivers/oprofile/cpu_buffer.c:
In function ‘oprofile_add_value’:
/home/jroth/kernel/spufs/arch/powerpc/oprofile/../../../drivers/oprofile/cpu_buffer.c:234:

cpu_buffer is defined by the DEFINE_PER_CPU_SHARED_ALIGNED macro:

If you only need to write from the core running Linux, and never
read the memory back, and the secondary core never writes the memory,
your userland program can simply do dcbst on it after it wrote it.
Otherwise, if your CPU has BAT registers, you could use those to
force that memory region as non-cacheable (be careful, BATs are not
allowed to overlap each other).
If these things won't work for you, you need to do some simple device
driver, and do non-coherent DMA from it (you can view the secondary
core as an I/O device like any other).

Hm. Hopefully ePAPR will be released soon.

* Re: Predefined Compiler Flag for CROSS_COMPILE in ELDK

In-Reply-To: <m2tzhjxorq.fsf@ohwell.denx.de>
Detlev,
-mcpu is deprecated:
HOSTCC scripts/basic/fixdep
`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.
scripts/basic/fixdep.c:1: error: bad value (405) for -mtune= switch
make[1]: ** [scripts/basic/fixdep] Erro 1
make: ** [scripts_basic] Erro 2
then I put -march=405 and give this errors:
scripts/basic/fixdep.c:1: error: bad value (405) for -march= switch
scripts/basic/fixdep.c:1: error: bad value (405) for -mtune= switch
make[1]: ** [scripts/basic/fixdep] Erro 1
make: ** [scripts_basic] Erro 2
See a piece of my Makefile:
HOSTCC = gcc
HOSTCXX = g++
HOSTCFLAGS = -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer
-march=405
HOSTCXXFLAGS = -O2
How can I do this?

* Running a section of code from internal memory
From: Sanal Kumar V K @ 2008-05-08 11:36 UTC (permalink / raw)
To: linuxppc-embedded
Hi All,
I am porting a GW/router application to embedded Linux for a product
based on SoC; following is the version information:
kernel: 2.6.10
uClibc: 0.9.27
gcc: 3.4.3
binutils: 2.15.94.0.2.2
A small part of the code needs to run from the on-chip "L2 scratch" for
getting optimum performance. I would really appreciate if some could
give me some pointers regarding the following questions:
1. Is #pragma section supported by gcc.
The compiler prints this warning "ignoring #pragma section" and the
pragma is ignored indicating that it is not supported. Is there any way
I can get the pragma working for gcc or any alternative?
2. Is there any patch available to modify the kernel thread creation so
as to place the stack and tcb in the user configured addresses for
kernel threads (similar to taskInit() in VxWorks)?
Thanks in advance,
Sanal

* [PATCH][v2] Add support for Analogue & Micro ASP837E board
From: Bryan O'Donoghue @ 2008-05-08 12:47 UTC (permalink / raw)
To: linuxppc-dev, Stephen Rothwell, Kumar Gala
Greetings.
Attached is a patchset to support the ASP8347E.
http://www.analogue-micro.com/ASP8347.html. Due to the fact that the board
shipped with a root filesystem that requires devfs, you have to run a different
rootfs with all current kernels. I've been using the 8xx root fs from the ELDK
via NFS, for this.
v2 implements all changes - bar ethernet aliases in the dts, as suggested
by Stephen Rothwell and Kumar Gala, to date.
Please apply.
Cheers,
Bryan

I wholeheartedly agree. After all, its the Local+ bus playing games
here. And fixing that for JFFS2 only ignores that other devices can
*and will* be connected on this bus. Unaligned accesses to such devices
will also fail (likely from mtd unrelated code) - and fail silently,
taking quite a while to figure out what is going wrong where.

How is this exactly supposed to work?

Yes, I should have mentioned this also in my original mail. If I
remember correctly, Greg mentioned that in this project, he has *300*
developers waiting to do something. None of the companies previously
claiming Linux had a driver problem showed up even when he contacted
them directly....

This would definitely be interesting.

* [PATCH v2] [POWERPC] Fix bootwrapper builds with newer gcc versions
From: Kumar Gala @ 2008-05-08 14:06 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
GCC 4.4.x looks to be adding support for generating out-of-line register
saves/restores based on:
http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
This breaks the bootwrapper as we'd need to link with libgcc to get the
implementation of the register save/restores.
To workaround this issue, we just stole the save/restore code from gcc
and simplified it down for our needs (integer only).
Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
---
e500 toolchains use a slightly different function name for the save/restore
stubs, go figure (support both).

Probably yes, but fsl_uli1575 needs some other changes for this.

These are similar to machine_initcalls, but works for the PCI fixups.
We need this to apply machine specific fixups for the same PCI devices.

With this patch we can choose which ULI fixups we want to apply

There are no changes to the fixups them selfs.

* [PATCH 3/3] [POWERPC] fsl_uli1575: change RTC quirk to work on MPC8610HPCD
From: Anton Vorontsov @ 2008-05-08 14:20 UTC (permalink / raw)
To: Kumar Gala; +Cc: linuxppc-dev
In-Reply-To: <20080508142005.GA6749@polina.dev.rtsoft.ru>
Currently fsl_uli1575.c's RTC quirk reads at ->start, but I got the RTC
working on the MPC8610HPCD only when reading at 0xa0100000-0xafffffff,
i.e. memory outside of behind-the-bridge devices' assigned regions.
This patch wasn't tested on the MPC85xxDS and MPC8641HPCN boards, I
don't have any of these.

* xilinx linux on a XUPV2P
From: Dr. Peter Hartmann @ 2008-05-08 13:56 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 859 bytes --]
Hello everybody,
I am trying to get the latest Kernel (2.6.25-rc9) from git.xilinx.com running on
a XUPV2P board. I generated the hardware using JH Kelms step by step list,
skipping points 6-8 and replacing point 9 by a more modern version of doing
this. When I boot the system.ace from the CF card, the bootloader talks to me
over the RS232, but as soon as it tries to boot the kernel it hangs up.
I had 2.6.18-rc3 which I got from somebody else running this way. The reason I
intend to change is the UARTLITE driver, which seems to be included in the
latest kernel tree.
I use Platform Studio 9.1.02i which I also used for the 2.6.18 Kernel.
Has anybody yet got this to work out with 9.1.02i ??
Would it be possible for somebody to give a dummy like me the steps you took to
get it working on your board? I'm really lost here. Thanks!
Thanks in advance!

* Re: MPC5200b MMC over SPI into PSC6

Ok, maybe it's better to start from the beginning.
Now I'm using a Lite5200b board, just to avoid problems with my
hardware, and I'm trying to have a bootable kernel.
With kernel version 2.6.24.6 I do the following commands
$ make ARCH=powerpc lite5200_defconfig
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- uImage
then I copy the arch/powerpc/boot/uImage and a rootfs.uimage on the
board, but uBoot stops at the beginning:

* FW: porting pci driverfrom arch=ppc on kernel 2.6.16 to arch=powerpc on 2.6.24...
From: Mike Timmons @ 2008-05-08 15:28 UTC (permalink / raw)
To: linuxppc-embedded; +Cc: scottwood
Thanks for the help Scott. Simply getting my irq from the pci device
structure in my probe callback following successful PCI driver
registration was the trick. I now have my Fujitsu CoralP driver running
under the 2.6.24 kernel on the Lite5200b (although I have a HW problem
on my product board that confused my efforts). Regardless, I'm now
confident I'm doing this correctly, thanks to you help.

No, clearing interrupts is device-specific.
Have you verified that the device does not think it's generating an=20
interrupt during the interrupt storm? Do other PCI cards work?

Right; some concepts need to be explained now... There is a major
difference between arch/ppc and arch/powerpc. In arch/ppc, the kernel
is hard coded with the list of devices in the system. In
arch/powerpc, the list of devices is captured in a data structure
called the Flattened Device Tree (FDT). fdt data structures are
generated from the .dts (device tree source) files in
arch/powerpc/boot/dts/.
When you build a uImage with arch/ppc, you get a hard coded kernel
that works with u-boot: "bootm <kernel_addr> <ramdisk_addr>"
When you build a uImage with arch/powerpc, you get a dynamic kernel
that needs to be passed the device tree blob on boot. Newer u-boot
supports dts booting: "bootm <kernel_addr> <ramdisk_addr> <dt_addr>"
or "bootm <kernel_addr> - <dt_addr>" if you're not using a ramdisk.
However, if you've got an older u-boot version installed on your
board, you need to create an image that binds the device tree into the
kernel image. This is called a "cuImage". So, instead of doing "make
ARCH=powerpc uImage", you should do "make ARCH=powerpc
cuImage.<boardname>". This 'wraps' the kernel with a boot wrapper
that includes the device tree blob but maintains compatibility with
the old style uImage format.
For example, use "make ARCH=powerpc cuImage.lite5200b" to build an
image for the lite5200b board. The build scripts will use the
lite5200b.dts file in the dts directory for building the image. If
you add "fabios-fantastic-board.dts" to arch/powerpc/boot/dts, then
you can build "cuImage.fabios-fantastic-board". :-)

ARCH=ppc and ARCH=powerpc are completely different beasts. Forget
that you even know about ARCH=ppc for this entire exercise.

* mmap problem in device driver and application program.
From: MingLiu @ 2008-05-08 15:33 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 2127 bytes --]
Dear all,
I had some problem when I use mmap() file operation in the device driver file operation. My situation can be described as:
1. I reserve 2MB DDR memory as a look-up-table (LUT) for my customized device. The physical start address in the memory is 0x03000000 and the size is 2MB.
2. In the device driver, I use mmap file operation to make this memory area directly accessible by application programs. In the mmap file operation, it looks like:
if(remap_pfn_range(vma, vma->vm_start, vma->vm_pgoff, vma->vm_end - vma->vm_start, vma->vm_page_prot)){ return -EAGAIN; }
3. In the application program, I read from a file and initialize the LUT area. I use the following sentence to mmap the physical address into a virtual one which could be accessed by the application:
// the physical address is from 0x03000000 with a size of LUT_SIZE_IN_BYTE equal to 2MB
lut_mem_base = (unsigned int *) mmap(0, LUT_SIZE_IN_BYTE, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0x03000000);
Then, I initialize the LUT area with the virtual address specified by lut_mem_base.
for(i=0;;i++){
fread(&buf, sizeof(unsigned int), 1, fp);
*(lut_mem_base + i) = buf;
if(feop(fp)){
break;
}
}
4. After the initialization of the LUT memory area, in the device driver, DMA transfer will be enabled using the physical address of 0x03000000 as the source address. The destination is a register in my customized device. The data is fed from the memory to my device register.
HOWEVER, I found that the data fed to the device register is not the same as the one used to initialize the LUT memory. Maybe the DMA fetches wrong data from different addresses and feeds to my device. Since this is my first time to use mmap, I am not self-confident to my program, both in the device driver and in the application. Is there anything wrong with my mmap part? I will appreciate so much if some experts could give me some hints. Thanks in advance.
BR
Ming

Right. The words should be corrected.
Since the only way to get a certain non-cached map was the (ab-)use of
dma_mmap_coherent(), such a confusing wording was chosen.

And dma_mmap_coherent() would be a solution for it, I suppose.

The vmap() in sound/core/sgbuf.c can be omitted by adding proper PCM
callbacks (copy and silent) to handle SG-buffers. These are only guys
that access the linear buffer runtime->area.
Then we'll just need a proepr mmap PCM callback just calling
dma_mmap_coherent() for each SG page. Also, the default PCM mmap
should be fixed to use dma_mmap_coherent() appropriately. That's
all.
So, what we really need is dma_mmap_coherent() implementations...
