Using a different device than the one used by the serial console? Yes,
think so..

It doesn't have to be an enum, it could just as well be a #define,
if we find that to be better in some way (maybe compile-time).
The general idea is to convert run-time checks into compile-time
checks in order to improve the running kernel. If you have
// start code
enum {
FEATURE_1 = 1,
FEATURE_2 = 2,
PLATFORM_1 = FEATURE_1,
PLATFORM_2 = FEATURE_2,
PLATFORM_3 = FEATURE_1 | FEATURE_2,
FEATURE_POSSIBLE =
#ifdef CONFIG_PLATFORM_1
PLATFORM_1 |
#endif
#ifdef CONFIG_FEATURE_2
PLATFORM_2 |
#endif
#ifdef CONFIG_FEATURE_3
PLATFORM_3 |
#endif
0,
FEATURE_ALWAYS =
#ifdef CONFIG_PLATFORM_1
PLATFORM_1 &
#endif
#ifdef CONFIG_PLATFORM_2
PLATFORM_2 &
#endif
#ifdef CONFIG_PLATFORM_3
PLATFORM_3 &
#endif
FEATURE_POSSIBLE,
};
static inline int have_feature(unsigned long feature)
{
return (FEATURE_ALWAYS & feature) ||
(FEATURE_POSSIBLE & runtime_feature & feature);
}
int foo();
int bar();
int main(void)
{
if (have_feature(FEATURE_1))
return foo();
if (have_feature(FEATURE_2))
return bar();
return 0;
}
// end code
Then gcc will produce optimal object code for any combination
of CONFIG_PLATFORM_{1,2,3}. Of course I have to admit that the
header file is not exactly elegant ;-).

Can you please provide a specific example command you tried (and make

with a complete list of all output and error messages it produces?

Hi,
To change u-boot for your needs you will need to do approximately the
following:
copy include/configs/MPC8260ADS.h to include/configs/YOURBOARD8260.h
Print out the the file and sit down with the 8260 ref. manual. Adjust
the YOURBOARD8260.h to fit your needs. (If you are not a HW designer
this will definitely take you some time)
Added a new directory
board/yourboard8260
copied the following files from board/mpc8266ads to board/fox8275:
config.mk
flash.c
Makefile
mpc8260ads.c -> yourboard8260.c
u-boot.lds
Changed the files to fit the your board.
Changed the main Makefile to support a new target
> YOURBOARD8260_config: unconfig
> @./mkconfig $(@:_config=) ppc mpc8260 yourboard8260
good luck

A kernel not build with AltiVec support will just
SIGILL any user process that tries to use it (and
MSR[VEC] = 0).
The code here can safely be #ifdef'ed out (but note
I only looked at the code, I didn't test it ;-) )

But maybe you want to read some more things about devfs, udev, ... /etc/devfsd.conf
before you know what you are doing there?
Well... all that depends on your kernel/system config a bit...

You'll probably get most objection from the PReP users, for whom
getting back a few hundred kB is a big deal. (Maybe we should just
buy both of them a G5 or something. 8-)

* non-inlined versions of local_irq*
From: Kumar Gala @ 2005-09-15 15:12 UTC (permalink / raw)

Anyone know why on ppc32 we have non-inlined versions of:
extern void local_irq_enable(void);
extern void local_irq_disable(void);
extern void local_irq_restore(unsigned long);
extern void local_save_flags_ptr(unsigned long *);
From looking at the code they are never used. Just wondering if
this was for debug or some other reason.

* PPC4xx cleanup
From: Stefan Roese @ 2005-09-15 16:03 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <20050830083859.B5925@cox.net>
Hi,
I am right now testing and cleaning up some of the AMCC 4xx eval board ports
to better support U-Boot as firmware. One question before I begin to send a
few patches:
All of the 44x boards I looked at (e.g. Ocotea) have to be extended in the
platform file (e.g. platforms/4xx/ocotea.c) to not only copy the bd_info
struct from r3, but also check r4 and r6 for initrd and kernel command line
passing from the bootloader. Instead of adding this code to all different
platform files, I would like to move this code to the common function
"ibm44x_platform_init" (syslib/ibm44x_common.c) like it is done in the 40x
ports "ppc4xx_init" (syslib/ppc4xx_setup.c).
Any objections/remarks?
Best regards,
Stefan

Sounds great to me. This will have to wait to go in mainline until
after 2.6.14 is out though.

OK. I dug up some data.
Compiled ppc32 *_defconfig across the page.
Section down the left. All numbers are 4K pages.
OF is the so-called "__openfirmware" section.
pmac ibmchrp stx_gp3 mpc8555_cds
--------------------------------------
pmac 10 7 0 0
prep 2 2 0 0
chrp 1 1 0 0
OF 2 1 0 0
init 47 46 23 32
Over in arch/ppc/mm/init.c this gets done:
printk ("Freeing unused kernel memory:");
FREESEC(init);
if (_machine != _MACH_Pmac)
FREESEC(pmac);
if (_machine != _MACH_chrp)
FREESEC(chrp);
if (_machine != _MACH_prep)
FREESEC(prep);
if (!have_of)
FREESEC(openfirmware);
Toss sections that don't match your _machine.
Everyone tosses init section.
Embedded boards will take no hit.
Ppc64 currently does not have these special sections
and hence will see no impact here.
That is the cost of removing these section identifiers.
So, is everyone prepared to live with these few pages
of occasional increased image size and remove the
special sections?
Thanks,
jdl

If they care that much they should submit a patch to build a PReP
specific kernel that doesn't include this stuff. And while you are
buying G5's for people send one my way :)
I vote that we just get ride of this sections stuff for prep, pmac,
of, chrp and if we want to reduce the code size make it a compile
choice to build specific kernel's that dont include the crap that the
others need. (especially based on the numbers that Jon has posted
for size).

I get the idea now, how about we make CPU_FTR_ALWAYS &
CPU_FTR_POSSIBLE just #defines and leave it to various sub-archs to
define CPU_FTR_POSSIBLE if they want to.
I see the classes of for FTR_POSSIBLE: CLASSIC_PPC, 8xx, 4xx, FSL-
BOOKE, PPC64 (maybe more subclasses here).
The hugh enum while useful, is just really ugly and I can't believe
it's worth it for the ~60 cases we are using cpu_has_feature() in.

Well, we have something like 20 or 25 VME machines controlling
experiments here, some with only 16Mb of RAM. The lifetime
of these systems is often of the order of 20 years (we shall
finally get rid of our TMS9900 processors with 32kB in November,
they were bought in 1982 I believe).
So yes, I object strongly object if I don't have a way
of removing useless PMAC code. The kernel is already very
bloated compared with the 2.2 we started with, which was
well below 1MB with the minimal setup: serial console, root
on NFS, no swap, some locally modules to control the PCI<->VME
bridge and what is behind on the VME bus.
