Hello everyone,
I'm quiet new to Linux, but would like to learn more of it.  At the
moment I am using it as a learning tool and someway to have a nice
version of GCC around.

Current status : SA-RiscPC, 33Mb Ram, Successfully installed Linux first
time (new installer's ace!), Network connection works fine, X11 works
fine (got Afterstep as a WindowManager), Chimera works blah blah...

Anyway questions...

1) I am looking to use ARMLinux (when I'm booted into it), not just have
it there as a server.  Please could anyone tell me if they have
succesfully installed and used the following - Pine and Pico.  Also on
a more substantial note, is there anyway (what-so-ever) to get some more
heavy weight apps running - ie. WordPerfect and Netscape?

2) Are there any precompiled binaries out there (other than Chris
Sawyers site - sorry if that's spelt wrong), or any sites with advice on
compiling code under ARMLinux...

Thanks for reading this far :-)

Yours Sincerely,
Ryan

I have ben studying the ARM 2.3.39 code and have these questions and
comments.

Any other thoughts?


head-armv.S, setup.c, proc-arm6,7.S:
  Why does the system use dynamic detection of processor id's and
  architectures? The code would be simpler and faster if configuration
was
  used to specify those values. Making it no longer necessary to loop
through
  these lists. (SAM)

  If the lists are still needed should the lists in head-armv.S and
setup.c be
  collapsed into one list?

head-armv.S:
  Uses magic numbers in __lookup_processor_type '#36' and in
  __lookup_architecture_type '16'. Should these be replaced with
calculated
  constant definitions? Where should they be defined? (procinfo.h, ???)
(SAM)

  The macro 'inituart' is defined but never referenced. Should it be
moved to
  debug-armv.S?

setup.c:

  setup_processor() - The 'for loop' is repeating what was just done in
  __entry in head-armv.S. It appears to be impossible to make the "CPU
  configuration botched..." message be emitted. (SAM)

Dear All:

  I want to build an arm tool chain.

  So, I downladed source package of glibc2.1.2, gcc-2.95.2, 
  binutils-2.9.5.0.27 and linux kernel 2.2.14.

  And try to build a cross-platform version of them with
  a pentium machine running RedHat 6.0.
  The native version of gcc is egcs 1.1.2, glibc is glibc 2.0.x.

  After I successfully built binutils, gcc, and linux kernel,
  however, I encountered

  " ../elf/ld-linux.so.2: undefined reference to `__libc_global_ctors' "

  error messgae when I am building glibc for ARM!!
 
  What happened??
  Could anyone tell me how to solve this problem??

  Thanks!!
  kirk

Speed is not a big deal for startup code that is only executed once.  It's 
useful to be able to run the same kernel on more than one machine and CPU 
type.

Yes, very probably.

What's the point in making a lookup which only happens once fast?  The
lists are needed to cope with kernels which can run on multiple
architectures.  (eg, it is possible to compile one kernel for EBSA285,
CATS and NetWinder machines and have it work on all of these).  Also,
some architectures may have different processors contained within.
(eg, RiscPC may be fitted with ARM6, ARM7 or StrongARM).

Without the dynamic detection, you'd probably end up with a total of
around 30 kernels only able to run on a specifically configured
machine.

>   If the lists are still needed should the lists in head-armv.S and
>   setup.c be collapsed into one list?

Yes and no.  The processor and architecture lists must be independent.
I think you're thinking of the architecture lists more.

The '16' is defined as the entry type of an assembly generated table
(contained within the same file and indeed within close proximity) -
there is absolutely no need to do anything different.  Anyone modifing
the code should realise what this is doing.

The '36' is commented as a sizeof (struct).  Since sizeof() is a C thing,
it doesn't work in assembler.

I don't have this.

Correct, but with one difference.  The one in head-armv.S is running in
a different memory space, accessing the data via a physical address,
whereas the one in setup.c is using virtual addresses.

It is possible to use the assembler version and convert the address, so
this could be done.

If the kernel can dynamically detect which processor and architecture it is
running on, then you don't need to build separate kernels for each.  If you
only have one processor/architecture combination, then it doesn't matter,
but if you're supporting multiple it's much easier this way.  

This code is small and only gets executed once at startup, so it doesn't
consume much time.  There is a complexity issue with maintaining this code.

I would vote in favor of this suggestion.  I would like to see the
architecture data collected into a section, like the processor data is, with
each entry identified by the registered architecture number, rather than
position, so that the architecture data could be moved into the
architecture-specific files.

Using a section for the procinfo and the architecture info would allow the
linker to calculate the currently manually maintained constants (#36 etc).
Accessing this data from assembly precludes the direct use of assembly
language, but we could store the necessary field offsets in variables that
are initialized via sizeof() and offsetof().

"vote"?  I wasn't aware that we had a general election today! ;)

There's one problem here - there aren't really any suitable per-architecture
files to move it into, and I'm dead against creating some just to store
this information.

The original idea behind the two lists was to (eventually) provide some way
of telling the user that they were running an incompatable kernel for their
architecture, but the code didn't materialise ;(

That's, erm, even more disgusting than the arch/arm/lib/constants.h hack,
and will preclude the use of nicities like 'ldm'!

Actually, that seems like rather a good idea.  The `fixup' code that is 
currently in setup.c and surrounded by ifdefs could move there also.

Hello all!

Finally managed to locating and attempting to compile the Pine email
proggy.  The compilation of Pico and Pilot worked out fine, and it's
handy just having them there, (using build options of Lnx).  Does anyone
here have experience of compiling Pine and could spare a few moments to
helping a beginner?

Versions	ARMLinux with V2 kernel, pine sources for V4.21
Machine		SA RiscPC

Yours Sincerely,
Ryan

  Thanks!! It now can be normally built.

  However, could you tell me why this error occurs??
  And if I meet the similar error again, what I can do
  to solve it?? Chagne another version of glibc or ...??

  Have a nice day!

It's an incompatibility between the version of binutils you are using and 
older libcs.

Mozilla will run.  WordPerfect probably isn't hopeless either; ask Corel.

Due to popular demand, I've written some install instructions for installing
Debian Linux on a RiscPC.

If you don't want to download a number of large files, and you don't want to have to type serveral involved things at a Linux command line, then you're probably better off waiting for the forth-coming CD from Aleph1.

However, if you're impatient, and don't mind hacking about with Linux settings, then this may be for you.

You can find the instructions at:

http://www.erble.freeserve.co.uk/

Within the sk_buff structure is a field called 'len' that is supposed to
be the length of the actual data. What is that measured in? Bytes? 

Thanks in advance.

All the links on http://www.arm.uk.linux.org/docs/ are bad. I need the FAQ

Is there anywhere else i can get it?

Specifically, I want to know what to do about lengths of filenames in
riscos 3.5, ie. how to get around the 11 char limit

I'd prefer the faq, just incase i have any more problems, which is likely
:)

Oops, that's a result of me reorganising the site a bit over the weekend.
It should be fixed now.

Hi all,

      The first question, I use angelboot to upload the kernel and=20
ramdisk from nico ftp site to SA1100 multimedia development=20
board. The minicom show the kernel panic "can't find ramdisk=20
at start 0".

     And I upload the kernel and ramdisk to the board. I can't see
any the result on the minicom application. What kernel configure
should I choose? I use the kernel-2.2.12 with patch-2.2.12-rmk1
and diff-2.2.12-rmk1-np13, compiled with egcs-1.1.2.

    The second, nico use the kernel based on Linux 2.2.13 with patch
2.2.13-rmk and diff-2.2.13-rmk2-np14, compiled with egcs-1.1.1.
But I can't find the patch file for egcs-1.1.1. Where can I find it?
Or can I use egcs-1.1.2 to compile it??

Your advice is high appreciate!!
                                                                         =

	diff-2.2.12-rmk1-np13 does not work on my Brutus, either.

	You can try diff-2.2.12-rmk1-np12.

Please try diff-2.2.14-rmk3-np15.  2.2.12-rmk1-np13 is broken.  Also see
Documentation/arm/SA1100/Brutus for the address where your ramdisk image
must be loaded.  It may have changed at that time.

egcs-1.1.2 should be fine.  Otherwise use gcc-2.95.x with 2.3.x kernels.

Is anyone working with this evaluation platform?  Looks like I get the lucky
job of bringing Linux up on this beast.  I was able to succesfully build a
working ARM cross-dev toolchain with glibc- we have a number of things
written in c++ to try to port- and if I can ever get the board away from the
marketing dept. I'll be able to start on it.  Comments, warnings, war
stories welcome...

	When I compile Linux 2.2.12 using binutil 2.9.5.0.29, I got the following error message:
%make zImage
...
arm-linux-ld -T /home/murphy/armbuild/linux-2.2.12/linux/arch/arm/vmlinux-armv.lds -e stext -Ttext 0xC0008000
arch/arm/kernel/head-armv.o arch/arm/kernel/init_task.o init/main.o init/version.o \
......
arm-linux-ld: target elf32arm not found

	From the release note of binutils-2.9.5.0.29, I have some hints:
To get the correct behaviour from gcc, amend the *link section of your specs
file as follows:

*link:
%{h*} %{version:-v}    %{b} %{Wl,*:%*}    %{static:-Bstatic}
%{shared:-shared}    %{symbolic:-Bsymbolic}    %{rdynamic:-export-dynamic}
%{!dynamic-linker: -dynamic-linker /lib/ld-linux.so.2}    -X
%{mbig-endian:-EB} %{mapcs-26:-m armelf_linux26}
%{!mapcs-26:-m armelf_linux} -p

	I guess it is necessary to modify the 'specs file'.
	But, where is the 'specs file'?

Do `gcc -v`.  The output will tell you exactly where it is.

Hello;

Where the gcc specs files resideds depends upon the options you selected
when you created the tool chain.  You can the specs file with:

find / -name specs -print

or

look for a directory structure like:

/skiff/local/lib/gcc-lib/arm-linux/2.95.2

This is where my specs file is stored, because I used the Prefix of
/skiff/local with the Target of arm-linux and Version 2.95.2.

I hope this helps.

Subject: compile 2.2.12 with binutil 2.9.5.0.29



	When I compile Linux 2.2.12 using binutil 2.9.5.0.29, I got the
following error message:
%make zImage
...
arm-linux-ld -T
/home/murphy/armbuild/linux-2.2.12/linux/arch/arm/vmlinux-armv.lds -e stext

init/version.o \
......
arm-linux-ld: target elf32arm not found

	From the release note of binutils-2.9.5.0.29, I have some hints:
To get the correct behaviour from gcc, amend the *link section of your specs
file as follows:

*link:
%{h*} %{version:-v}    %{b} %{Wl,*:%*}    %{static:-Bstatic}
%{shared:-shared}    %{symbolic:-Bsymbolic}    %{rdynamic:-export-dynamic}
%{!dynamic-linker: -dynamic-linker /lib/ld-linux.so.2}    -X
%{mbig-endian:-EB} %{mapcs-26:-m armelf_linux26}
%{!mapcs-26:-m armelf_linux} -p

	I guess it is necessary to modify the 'specs file'.
	But, where is the 'specs file'?

Not being an expert on ARM cpu's and architectures can someone tell me
if the coprocessor interface (p15) is part of the CPU (ARM6, ARM7)or
part of the architecture (v3, v4, v4T)?

Which of the two forms below should be used


ENTRY(cpu_arm6_reset)
ENTRY(cpu_arm7_reset)
  mov r0, #0
  mcr p15, 0, r0, c7, c0, 0  @ flush cache
#ifdef CONFIG_CPU_32v4
  mcr p15, 0, r0, c8, c7, 0  @ flush TLB (v4)
#else
  mcr p15, 0, r0, c5, c0, 0  @ flush TLB (v3)
#endif
@  mcr p15, 0, r0, c5, c0, 0  @ flush TLB
  mov pc, lr


---------------------------------------
ENTRY(cpu_arm720T_reset)
  mov r0, #0
  mcr p15, 0, r0, c7, c0, 0  @ flush cache
  mcr p15, 0, r0, c8, c7, 0  @ flush TLB (v4)

hi folks,

we are using gdb 4.18 with ben williamson's patch( benw5 ) to emulate
CL-PS7110.

we are able to run simple executables ( e.g with s printf ) which are
statically linked but the ones which are dynamically linked are causing
kernel panic.

if any of you out there are able to run dynamically linked programs, pl.
tell me how.

any ideas/guesses on why it may not be working  would also be appreciated.

at the risk of cliche, thanks a ton,
slater.

Use linux-2.2.14 + rmk patch if you have binutils 2.9.5.

This has been discussed before, many times.  Please check the list archives at 
<http://www.armlinux.org/~webmail/linux-arm/>.  You might also like to review 
the binutils release note or upgrade to a newer kernel.

It's part of the architecture.  You may find that ARM720T has more in common 
with SA-1 than ARM710.

This one.  I'd rather CONFIG_CPU32v4 didn't get involved in this sort of thing 
- it only exists to help choose compiler flags.

Hello,

I am posting this message also to the linux-arm mailing list. I am 
sorry if this may be considered as a mismatched subject, but I am
curious if any readers of this list may have experience or suggestions
on the subject of an emulator for use in arm-linux development projects.

Does anyone have any experience with any products from Sophia
Systems,Inc. ?

Our engineering group is considering their UniSTAC StrongARM SA-1110 ICE
product for use in a product development project here. 

We are using the GNU tools running on Red Hat 6.0 Linux boxes.  I am
concerned at their lack of support for UNIX based development, but they 
seem to be about the only available emulator that I have found so far
for 
the StrongARM SA-1110.
 
Does anyone have any experience (good or bad) with this particular
product or with any other Sophia Systems emulator products?

Can anybody recommend an emulator for use with the SA-1110?


Thanks,


David J. Croyle

I don't know what the SA-1110 has to offer an ICE, so I'll just make a 
general comment: the classic ICE approach (monitor all the wires going 
into the CPU) is long obsolete.  It doesn't have any value at all for
CPUs with effective caches.

IF your CPU has built-in mechanisms for ICE-like debugging, such as
trace, watch, break setting mechanisms, then you're in good shape.
These days, those mechanisms are often provided via the JTAG port,
which gives you ICE-like capabilities at extremely low cost (hundreds
of dollars vs. tens of thousands for clasical ICE).

Some CPUs provide watch etc. mechanisms under program control, which
means you can let gdb or equivalent control them.  

When evaluating such things, consider very carefully what the actual
primitives are that exist in the hardware.  For example, the MIPS
RM7000 has functions like this, but when you dig deeper, you find that 
what's actually there is not useful at all (not good enough for real
work).

What does the panic look like?

hi phil,

here is what the panic looks like ( test2 is a dynamically linked

as u can see, the kernel panics and enters an infinite loop. after i came to
the gdb prompt, i ran it again to get the second part of the dump i have
sent.

i should mention here that the initrd i am using uses the BusyBox utility (
www.lineo.org ) which was statically linked.

we had our own initrd with the shell and commands dynamically linked. none
except the built in commands ( echo ) worked.we add the dump for this too -

Greetings.

I am currently looking to employ an ARM Linux kernel developer here in
the U.S. If you are interested, please email and we can discuss details
offline. Also, does anyone know of some other places to post besides 
the ARM-Linux and Linux kernel mailing lists? Thanks.

-Steve

<font size=2>Hello... 
<br>

<br>
I have a ebsa285 with only boot flash 512K.
<br>

<br>
I made a linux-arm 2.2.12 kernel(footbridge) and other tool chains including bios-1.06 and it's patch(serial loading and flash loading)
<br>

<br>
Now my problems are....
<br>

<br>
1) My kernel is 420K and bios is 13k.
<br>
   How can I flash write the kernel with bios at 512k flash(0x41000000 - 0x4107ffff) to boot from flash ?
<br>
   I think it's some what different LOAD_ADDR and MAGIC_??
<br>
   
<br>

<br>
2) To load kernel using 3c59x and tftp and To load kernel using serial ymodem, Could someone give me a simple direction where and how can I use the netdev as bootdev?
<br>
And how can I download the kernel using ymodem in minicom ?
<br>
Some procedure may be more helpful for me.
<br>

<br>
Thank you...
<br>

<br>

I'll assume you used my patch to bios-1.06 which is also available as
ftp://ftp.netwinder.org/users/n/nico/ebsa285-bios-1.06.diff2.

Here's what you should do:

- You should read and understand the instructions at the top of
bios/drivers/char/flash.c.  Modify and recompile your kernel accordingly.
If you store the BIOS at 0x41000000, you could store the kernel zImage at
0x41008000 which leaves you 480k for its size.

- Enable flash booting option in bios/include/bios/config.h.

- Change link address at the top of bios/Makefile for TEXTADDR=0x41000080

- Build the BIOS.

- Make up your flash image like this:

	dd of=flash.bin if=bios
	dd of=flash.bin if=zImage bs=1k seek=32

You then can burn the flash.bin file on your flash chip.

If the bios stalls half way through, you may try commenting out the
isa_init() call in bios/init/main.c.  At least it helped me since I don't
have any ISA bridge.

The 3C59x bios driver is not as complete as the one in the kernel.  If you
have a 3C90x card, you're out of luck.

> And how can I download the kernel using ymodem in minicom ?

Simply select the "serial port" boot method, and when prompted, send your
zImage over with minicom's upload/y-modem function.

Hi there,

Have there been major changes to the kernel from v2.2.7 to v2.3 that
require glibc recompilation?

I'm just wondering because I can not start any executables that fork()
somewhere. Especially the combination of fork() and waitpid() fails
every time.
It seems that the fork syscall succeeds. When running bash as init
task, I can execute a command with 'exec whatsoever'. This of curse
kills the init task when 'whatsoever' finishes, but just type the
command at the command line (in that case bash fork()s and waits for
the task to finish with waitpid) results in the same kernel panic that
init shows me every time.

The kernel itself however shows no sign of malfuctioning. It boots up
and initializes all the devices correctly. All the tasks that fork
from the kernel during startup don't panic the kernel at all. So the
glibc is the only thing that still remains for me as the source of the
trouble.

Thanks.


PS: Sorry for writing that here, I have difficulties mailing to
linux-arm-kernel.

Not that I know of.  There are new features that you won't get access to 
without recompilation, but old binaries should still run fine.

Please give more details.  If there's a kernel panic, what does it say?  Also, 
what kernel version are you using; do later 2.2 kernels (such as 2.2.14) work 
for you?

>All the tasks that fork from the kernel during startup don't panic the

Kernel threads are somewhat special, so I wouldn't rule out a kernel problem 
here.  The ARM7 support is not very well tested.

Hi folks,

Does anyone know how to use the equal GCC built-in variables 'etext',=20

I want to porting Linux to a proprietary ARM7 core MCU, but the above=20

If some one knows or experiences the compiler compatibility issue, plz=20
give me some advise.

Thanks a ton.

You will probably have far worse problems than this if you want to build 
the kernel with non-GNU tools.  Why don't you want to use GCC and GNU binutils?

These symbols are actually nothing to do with GCC.  They are created by the 
linker to delineate the various segments in the output image.  (I've never 
come across _fbss and _fdata, for that matter.)

I'm a newbie Korean linuxer - specifically to arm linux.

Since I'm working on the embedded linux project for ARM, I have to build cross toolchains.

After lots of trouble I've built it successfully with many advices from 

http://inkvine.fluff.org/~chris/arm-tools.html

Yes. I could build the Linux kernel 2.2.14 with patch-rmk4 successfully.

But the vmlinux image was elf-32littlearm format and the evaluation board engineer said that I have to build a big-endian image.

So I've fiddled out Makefiles and Rules.make to add  -mbig-endian switch to gcc and -EB switch to ld.

And finally got error about arch/arm/lib/extractconstants.pl with objdump output of big-endian compiled objects.

I've been reaching big-endian kernel image ( Yes, It's the goal ) ...

But I had a doubt that "Is this kind of things right? If I have a toolchain configured to support big-endian default?"

So I returned to web-life, finding any information... then I've got information from the web page mentioned at the beginning.

It's the target name.

In "Picking a target name" section from the web page...

Not only arm, but armv4l and armv4b are also target names.

I've tried it on binutils-2.9.5.0.29 first, but got errors like this.

-----------------------------------------------------------
[root@fraser binutils-2.9.5.0.29]# pwd

Configuring for a sparc-sun-solaris2.6 host.
Invalid configuration `armv4b-linux': machine `armv4b' not recognized
Unrecognized target system name armv4b-linux.
------------------------------------------------------------

What's the point of problem? Are there any patches to support armv4b? Is the word "armv4b" badly located?

Please answer.

Thanks in advance. 

Have a nice day.

I don't know of anybody else using Linux on a big-endian ARM.  The kernel 
sources in CVS have at least some token support for big-endian compilation
but it is completely untested.

>Invalid configuration `armv4b-linux': machine `armv4b' not recognized

This is a bug in binutils (more specifically, in the config.sub script).  I 
will try to get it fixed.  You could try `armeb-linux' in the meantime; that 
might possibly have the desired effect.

Why would you absolutely need big endian?  ARM processors are able to do
both and current Linux kernels expects little endian.

I am interested in getting Linux to run on a chip designed by my company.
Our chip is a Configurable System-on-Chip (CSoC) with an ARM7TDMI core. We
do have a memory protection unit, but it is rather crippled when compared to
the standard ARM MMU. Using our protection unit, we could define up to 8
areas of memory with various protection; I'm assuming we could use this
functionality to allow Linux to run with swapping, but I'm afraid of the
effort we'd have to put in to make this happen.

We also have programmable logic on the chip in the form of an FPGA, so we
could do extra things in hardware if we needed to. Do you think the best
course of action would be to try to hack ARM Linux to work with our memory
protection unit, or should we use uCLinux instead? What would be the
benefits of using a fully-functional Linux, as opposed to uCLinux? Would the
benefits outweigh any extra work that would be needed?

Thanks for any help,
Eric Newman

Hello all.

I am considering making relatively simple PCBs to allow one to use an IDE
hard drive over the PCMCIA interface (this would requre an external power
supply for the HDD) and a CompactFlash to PCMCIA adaptor (the CF card
would be used in "TrueIDE" mode). I'm also considering an IDE to PCMCIA
interface which would physically contain laptop size 2.5" HDD.

I've successfully been able to get an ARM Linux kernel ID an IDE hard
drive on my Brutus board with one adaptor I made, however it is not near
reliable, hence the desire to make a PCB. To cut the cost of th boards,
I'd like to offer them to anyone else here who wants one (@cost). Please
let me know if you are interested. I have not yet finished making the
design or finished getting quotes.

These adaptors are passive and I have the pinouts available. If someone
else has access to PCB making facilities, please let me know. The layout
would be something like a PCMCIA surface mount connector, an IDE surface
mount connector and traces ~12mils wide with 12mils spacing.

Thanks,
Vasant.

Once upon a time I tried to build big-endian GNU ARM tools for embedded use.
I didn't really need big endian but I just preferred it since all our other
microprocessors are big endian.  At the time (and I doubt if this has changed
since), binutils didn't deal with big-endian correctly ARM since the BFD 
library assumes a single endianness for all relocations, both data and
instruction.  Turns out that for a big endian ARM, you must treat data as
big endian but instructions as little endian.  Binutils just plain can't handle
this.

Philip,

Thanks a lots. Although I am an advocacy of GNU but speak truly, SDT has
armulator and source (symbolic) debugger for me to hacking the kernel
with less pain (I think so).

So I would rather like to look for some methods which can work around
these built-in variables. If there are deadly no way to work around then I
will use GCC. But I still eager to know how to do a thing with
more than 2  ways.

Larry Wall said: There are more than one way to do a thing.

Philip, Thanks.
Somebody's advise here are still welcome and appreciated.

Artis J.

There is some hardware out there that is big-endian only.  A lot of the 
Samsung products seem to prefer big endian operation for example.

Well, I won't say it's impossible to build the kernel with the ARM SDT.  But, 
personally, I would spend the time on either improving the GDB+ARMulator 
combination, or fixing GCC and/or SDT so that the SDT debugger can be used on 
images built with GNU tools.  (The latter should work in theory but there 
seems to be some incompatibility.)

The problem is that the kernel is full of GNU language extensions; __inline__, 
__attribute__ and the like.  Plus there is a fair amount of assembly code in 
GNU syntax.

Yes, I am working on the KS17C4000 from Samsung and I need to produce a big
endian code since Samsung's microcontroller are big endian. I do not know for
the moment if the kernel is able to run on this very processor but I looking at
it. Moreover, since it is a mmuless microcontroller, this will be also treated
in the uclinux-arm mailing list.
But I also want to know if this problem can be solved or it will be a hard work
to do with it ?

Thank you very much.

Hi,
Forgive me if this is a bit off-topic.
( I did skim the archives and could'nt
find what I wanted). Sorry again, if 
this is a beginner-ish question.

I want virt to phys page mappings for two 
flash banks (8Meg each) (the banks are
not physically adjacant) on an ep7211 based 
board.
Tried a loop of alloc_init_page() at PAGESIZE
increaments in setup_pagetables(). This works
for a limited number of mappings (but not
for the entire 2*8Meg).

Also what does alloc_init_section() do?


Thanks & Rgds,
Sreekrishnan V

Don't do this.

> Also what does alloc_init_section() do?

Don't use that either.

Add an entry to the mapping tables ("MAPPING" in 2.2, or the io_desc
in 2.3).  The routines that scan these tables will then sort out the
page or section mappings as appropriate to achieve your required mapping
at the least cost to the TLB.

PS, this is a kernel question.  Please post such questions to the
linux-arm-kernel mailing list, details are on the web site.

Compiling the kernel with non-GCC isn't really a good idea.  As Phil says,
a lot of the extensions are used.  In addition to this, a lot of the kernel
is tuned specifically to allow GCC to optimise effectively to produce
efficient code.

PS, this should really be on linux-arm-kernel.  See the web site for more
information.

Actually, who knows, the SDT compiler might generate sufficiently better code 
to negate this effect.

Greetings.

I would like to generate just a little discussion about kernel command line
boot options as related to the Linux ARM port. In my current system I have
an interactive boot loader that is located FLASH. I use it to load my kernel
into RAM and then boot it. It would be very useful to pass kernel options to
the kernel during development/prototyping. I realize that a lot of the ARM
ports are being used in embedded systems without a need for this, but to
support future development where people will/may have bootloaders in FLASH,
this could be useful.

It appears from my digging in the code that then only way to send any options
to the kernel is to put them in at compile time. 'arch/arm/kernel/setup.c'
contains the static character array 'default_command_line' which is set equal
to the string hard coded during kernel configuration. I have two possible
suggestions for passing options:

1) If the kernel is located in RAM, carve out 128 or so bytes located at a
   known offset in the kernel that the bootloader could place options into.

2) If the kernel is located in FLASH, ROM, etc.,  carve out 128 or so bytes
   at a know place in RAM the the bootloader could write options to.

The x86 kernels in conjunction with LILO use an approach similar to #1 as
far as selecting the root filesystem and other stuff. This is where I kind
of got the "idea". For my platform and project, I will need to have the
ability to pass boot options to the kernel. I wanted to get input from
those of you on the list and see what people thought and what mechanisms
they would employ before I started hacking away. Currently I am running my
kernel out of RAM so I will probably use method #1. After I stabilize my
kernel however, I will place my kernel in FLASH and then use method #2. I
look forward to hearing everyone's input. Cheers.

-Steve

If you arrange for your bootloader to pass a parameter block to the kernel you 
can put commandline options in there.  

See struct param_struct in <asm/setup.h>, the `param_offset' member of struct 
machine_desc (in arch/arm/kernel/arch.c) and so on.  This is more or less the 
same as your option #2 in fact.

No.

For a SA1100 system, look at BLOB instead.

BLOB is the bootloader Jan-Derk Bakker and I wrote for the LART (see
signature). Adam Wiggins ported (read: changed one or two constants) it to
PLEB. Have a look at:

Hello...

I have got under the error mesages when making gcc-2.95.1 with gcc-2.95-diff-990730.
I modified all the thing along to Francois Desloges's instruction.
binutils is ok.
My system configuration is
	redhat 6.1 linux
	intel pentium III
	binutils-2.9.5.0.27.tar.gz(no patch)
	gcc-2.95.1 and gcc-2.95-diff-990730 patch
	glibc-2.1.2.tar.gz
	glibc-crypt-2.0.111.tar.gz
	glibc-linuxthreads-2.1.2.tar.gz
	linux-2.2.12.tar.gz and it's patch.
	

'./configure ... ' may be good, 'make -i LANGUAGES=c' produce ubder error messages...
And glibc also has problem.

Yes, we have experience with blob on LART, and Adam Wiggins has experience
with blob on PLEB.

I think that's all there is. Or write your own bootloader, but in that
case you'd better use blob as a starting point.

Did you get exactly the "nNow send file with y-modem (^X to abort) ..."
prompt on your serial terminal?

If so, are you able to cancel that prompt with a CTRL-X?

If your answer is now to either one of those question, it means that you
have a serial connection problem in one way or the other.

Hi,

Does anyone know of a SVGALib that has been built for SA1100 running Linux.
I get a slew of errors when I try to cross compile it for the Arm processor?

Thanks,
Nikita

I can imagine. The last time I had a look at it, svgalib depended heavily
on the 80x86 CPU family. Unless you have a real SVGA hooked on your SA1100
system, I don't think it's worth porting.

Oops! I hate to followup my own messages, but JDB told me to have another
look at the CPU model. Sorry for the bad information.

No, AFAIK nobody has experience using blob on a SA1110. It can't be too
difficult, though. The SA1110 is just an SA1100 with a different memory
controller and some silicon bugs fixed.

Greetings.

I am booting the 2.3.51 kernel on my development board and the following is
the fixup code I run since my bootloader is not yet passing options to the
kernel:

static void __init
fixup_l7200(struct machine_desc *desc, struct param_struct *params,
             char **cmdline, struct meminfo *mi)
{
        ROOT_DEV = MKDEV(RAMDISK_MAJOR,0);
        setup_ramdisk( 1, 0, 0, 8192 );
        setup_initrd( __phys_to_virt(0xf1000000), 0x0018057d );
}

I upload my kernel and ramdisk image and below is what I get:

***********************************************************************
Serial driver version 4.92 (2000-1-27) with no serial options enabled
RAMDISK driver initialized: 16 RAM disks of 8192K size 1024 blocksize

kmod: failed to exec /sbin/modprobe -s -k binfmt-464c, errno = 2
Kernel panic: No init found.  Try passing init= option to kernel.
***********************************************************************

First, I have no idea why it is looking to load a module for the
serial port when I do not have it compiled as a module and obviously
I am pushing data over it. Any ideas on this?

Second, is it really necessary to use 'initrd' if I want to have a
ramdisk located in RAM and do not plan on mounting a "real" root
filesystem after it loads the initrd image? My understanding is that
the original purpose of initrd was to provide a small start up ramdisk
to load kernel modules so that booting could continue on to mount the
real working root filesystem. If I only want what is in my ramdisk, why
do I have to bother with initrd? Won't making a call to setup_ramdisk
above with the starting address in memory of my ramdisk do just fine?
I am still digging through the code to understand things better, so
please be patient. Also, if anyone has a ramdisk they would like to share,
all the better :). Thanks.

You forgot to install the linux kernel headers, or you did install them
but forgot to run "make config; make dep" in the kernel tree.

The above two lines are trying to tell you that it is unable to open
a console.  The kernel will try to open the console using /dev/console.
Check that your console has major,minor set to 5,1 in the ram disk.

binfmt-464c is the code for the ELF binary format.  Did you compile
ELF support into the kernel?  It appears that it isn't in there.

Please remember that the conventional ramdisk is normally loaded from
floppy in this case, not from RAM.  The way the ramdisks work, the
ramdisk data is not stored in a contiguous chunk either, so loading it
into the kernel is going to be non-trivial.
