Suprisingly this macro shows up in ~19 .c files. Only valid usage is
forward declaration of a later static definition with DEFINE_PER_CPU.
arch/m32r/kernel/smp.c + arch/m32r/kernel/smpboot.c is jsut one example.
Just a random comment not related to Steven's patches.

* PowerBook5,4 -- no sound?
From: Paul Collins @ 2006-04-16 14:39 UTC (permalink / raw)
To: linuxppc-dev
With Linus's current git plus the boot fix and some unrelated patches
(console font and bluetooth) sound no longer seems to work (nothing in
/proc/asound/cards), although snd-powermac loaded without complaint.
Is this a known problem?
Thingies below.

Well that's easy then, just configure PERCPU_ENOUGH_ROOM to be larger
when tracing is on in the -rt patchset? Or use alloc_percpu for the
tracing data?

Well I don't think making it per-cpu would help much (presumably it
is not going to be written to very frequently) -- I guess it would
be a small advantage on NUMA. The main problem is the extra load in
the fastpath.
You can't start the next load until the results of the first come
back.

I still don't understand what the justification is for slowing down
this critical bit of infrastructure for something that is only a
problem in the -rt patchset, and even then only a problem when tracing
is enabled.

Ok, you asked for a crazy idea, you're going to get it ;-)
You could take a fixed range from the vmalloc area (e.g. 1MB per cpu)
and use that to remap pages on demand when you need per cpu data.
#define PER_CPU_BASE 0xe000000000000000UL /* arch dependant */
#define PER_CPU_SHIFT 0x100000UL
#define __per_cpu_offset(__cpu) (PER_CPU_BASE + PER_CPU_STRIDE * (__cpu))
#define per_cpu(var, cpu) (*RELOC_HIDE(&per_cpu__##var, __per_cpu_offset(cpu)))
#define __get_cpu_var(var) per_cpu(var, smp_processor_id())
This is a lot like the current sparc64 implementation already is.
The tricky part here is the remapping of pages. You'd need to
alloc_pages_node() new pages whenever the already reserved space is
not enough for the module you want to load and then map_vm_area()
them into the space reserved for them.
Advantages of this solution are:
- no dependant load access for per_cpu()
- might be flexible enough to implement a faster per_cpu_ptr()
- can be combined with ia64-style per-cpu remapping
Disadvantages are:
- you can't use huge tlbs for mapping per cpu data like the
regular linear mapping -> may be slower on some archs
- does not work in real mode, so percpu data can't be used
inside exception handlers on some architectures.
- memory consumption is rather high when PAGE_SIZE is large

Sound doesn't work here on PowerMac7,3 either, it even oopses during
module loading.

Yeah, we already know this. The -rt patch was what showed the problem,
not the reason I was writing these patches.

It's because I'm anal retentive :-)
I noticed that the current solution is somewhat a hack, and thought
maybe it could be done cleaner. Perhaps I'm wrong and the hack _is_ the
best solution, but it doesn't hurt in trying to improve it. Or the very
least, prove that the current solution is the way to go.
I'm not trying to solve an issue with the -rt patch and tracing, I'm
just trying to make Linux a little more efficient in saving space. And
you may be right that we cant do that without hurting performance, and
thus we keep things as is. But I don't want to give up without a fight
and miss something that can solve all this and keep Linux the best OS on
the market! (not to say that it isn't even with the current solution)

On ia64 the percpu area is at 0xffffffffffff0000 so that it can be
addressed without tying up another register (all percpu addresses
are small negative offsets from "r0"). When David Mosberger
chose this address he said that gcc 4 would actually make
ue of this, but I haven't checked the generated code to see
whether it really is doing so.

Same reply... load i2c-powermac before snd-powermac. It's a bug in the
sound driver, but I can't be bothered fixing it at this point, better to
concentrate on the new snd-aoa and adapting it to work on all machines.

This is probably a big issue. I believe interrupt context in hrtimers
uses per_cpu variables.

That's also something that I'm trying to solve. To use the least amount
of memory and still have the performance.
Now, I've also thought about allocating per_cpu and when a module is
loaded, reallocate more memory and copy it again. Use something like
the kstopmachine to sync the system so that the CPUS don't update any
per_cpu variables while this is happening, so that things can't get out
of sync.
This shouldn't be too much of an issue, since this would only be done
when a module is being loaded, and that is a user event that doesn't
happen often.
We would still need to use the method of keeping track of what is
allocated and freed, so that when a module is unloaded, we can still
free the area in the per_cpu data. And reallocate that area if a module
is added that uses less or the same amount of memory as what was freed.

If it's just about hrtimers, it should be harmless, since they
are run in softirq context. Even regular interrupt handlers are
always called with paging enabled, otherwise you could not
have them im modules.

I guess this breaks if someone holds a pointer to a per-cpu variable
while a module gets loaded.

Ah, you're right. You said exceptions, I'm thinking interrupts. I was a

Argh, good point, I didn't think about that. Hmm, this solution is
looking harder and harder. Darn, I was really hoping this could be a
little better in space savings and robustness. It's starting to seem
clearer that Rusty's little hack, may be the best solution.
If that's the case, I can at least take comfort in knowing that the time I
spent on this is documented in LKML archives, and perhaps can keep others
from spending the time too. That said, I haven't quite given up, and may
spend a couple more sleepless nights pondering this.

Actually, the reason this is done is because the per_cpu_offset[] is
designed to be replaced by a register or an expression on archs which
care, and this is simple. The main problem is that so many archs want
different things, it's a very UN task to build infrastructure.
I have always recommended using the same scheme to implement real
dynamic per-cpu allocation (which would then replace the mini-allocator
inside the module code). In fact, I had such an implementation which I
reduced to the module case (dynamic per-cpu was too far-out at the
time).
The arch would allocate a virtual memory hole for each CPU, and map
pages as required (this is the simplest of several potential schemes).
This gives the "same space between CPUs" property which is required for
the ptr + per-cpu-offset scheme. An arch would supply functions like:
/* Returns address of new memory chunk(s)
* (add __per_cpu_offset to get virtual addresses). */
unsigned long alloc_percpu_memory(unsigned long *size);
/* Set by ia64 to reserve the first chunk for percpu vars
* in modules only.
#define __MODULE_RESERVE_FIRST_CHUNK
And an allocator would work on top of these.
I'm glad someone is looking at this again!

I used the watchdog timer on mpc8247 and mpc8271. The mpc8248 watchdog
should be the same. I used ppc_md.heartbeat to write to the watchdog

But I didn't found "string.h" under "asm-ppc", my asm is link to asm-ppc

Mike,
I tested several times last week but it didn't work for me.
I had made the changes in U-boot as you say, but it keeped
reseting at the time. In fact, in the log_buf I can see
several printk's after setup_arch (where ppc_md.heartbeat)
is assigned, but the watchdog counter is not reloaded.
Which could be the difference? I am using ramdisk,
and a MPC8248 clocked at 100MHz, but I don't think
this will be the reason.
Now, someone has proposed me to try reloading WDT in
printk calls. I will test.

Hi Rusty, thanks for the input.
Arnd Bergmann also suggested doing the same thing. I've slept on this
thought last night and I'm starting to like it more and more. At least
it seems to be a better solution than some of the things that I've come
up with.
I'll start playing around a little and see what I can do with it. I
also need to start doing some other work too, so this might take a month
or two to get some results. So hopefully, I'll have another patch set
in June or July that will be more acceptable.
I'd like to thank all those that responded with ideas and criticisms.
It's been very helpful.

We've checked the SDRAM. The timings (UPM) look fine. The problem
however is that linux does not hang until after a few processes are
started.
If we boot to linux and leave it as it is, everything is fine and the
board remains working. However each time a few processes (4-5 telnet
sessions for eg.) are started the system either panics or hangs (goes
dead).
Thanks in advance,
Akshay

I agree. Unfortunately, the i2sbus probing already fails, due to
requesting a memory region that is already (partially) claimed by other
resources:
request_mem_region(80000000 - 80000fff, i2sbus control)
