rwsems on ppc64 should really be using a 64-bit counter, not a 32-bit counter,
otherwise you limit the maximum number of processes to 32K-ish.
The counter should be "signed long" really.

Agreed, we should move to a 64bit count.

With a 64-bit counter, the constants should be:
#define RWSEM_UNLOCKED_VALUE 0x0000000000000000L
#define RWSEM_ACTIVE_BIAS 0x0000000000000001L
#define RWSEM_ACTIVE_MASK 0x00000000ffffffffL
#define RWSEM_WAITING_BIAS (-0x0000000100000000L)
#define RWSEM_ACTIVE_READ_BIAS RWSEM_ACTIVE_BIAS
#define RWSEM_ACTIVE_WRITE_BIAS (RWSEM_WAITING_BIAS + RWSEM_ACTIVE_BIAS)
Just like in the asm-s390/rwsem.h.

Thanks Roland, I've just pushed your patch with minor style changes
to my GIT tree.
I changed uint32_t -> u32 and moved emac_phy_done() functions to
ibm_emac.h. Booted new kernel on Ocotea and everything seems to be OK.

I'm not sure. This header definitly doesn't need it, but I suspect
seccompt.c expects to get it via this header.

The SMC was previously initialised, but I still upgraded to 2.6.14-rc2,
which includes your patch. It still doesn't work, the buffer descriptor
must be at a wrong address somehow since the board just hangs now in the
same routine.
I did manage to decode the message coming to the console with the two
leds onboard... it begun with "Linux ve", which at least looks like a
good boot-up message :)

No problem. I _can_ resubmit the patch with this fix.
However, I am not certain that I should yet.
But what do you wan to do with ppc32 land then?
Leaving it a "signed long" will limit ppc32 land but
not ppc64 folks. (No problem.) Or we can have it
be "singed long long" for ppc32 to also get 64 bits.
(Again, no problem.)
Also, this begs the question of the comment from Paul:
struct rw_semaphore {
/* XXX this should be able to be an atomic_t -- paulus */
signed int count;
Which, of course is:
typedef struct { volatile int counter; } atomic_t;
Changing the size of counter will cause bad sizes
due to the actual treatment of count as an atomic_t.
So. Should we, in fact, convert it to be an atomic_t
and further dispense with the casts?:
static inline void __down_write(struct rw_semaphore *sem)
{
int tmp;
tmp = atomic_add_return(RWSEM_ACTIVE_WRITE_BIAS,
(atomic_t *)(&sem->count));
And if we _do_ convert it to be an atomic_t, should _that_
be where the real type for count gets established?
And finally, I've been working on merging header files
under the vague guideline of "merge maintaining existing
functionality/breakage". I've been trying NOT to introduce
simultaneous "improvements" at the risk of breaking something.
To that end, I ask if the request to make 'count' be 64-bits
should be submitted as a follow on patch that stands on its
own and can clean up around it as necessary? Or do you want
it mixed in with this "merge" patch too?
Just need to know the preferences.
Thanks,

I dug around in this a bit. The nested includes here yield
a fairly wide distribution of availability of TIF_32BIT.
I'm hesitant to remove it in this "merge" patch, so I
will leave its removal to a follow on patch/effort.
New patch with #if test removed coming up.

I'd suggest "signed long" in both cases. A maximum of 32K processes on ppc32
is probably reasonable.

Paul can be wrong sometimes:-)
Changing to atomic_t would leave the 32K process limit in place.

You will not be able to use the standard atomic ops unless you increase them
to 64-bits on ppc64.

You should not do that unless you increase atomic_t to 64-bits on ppc64.

This patch is overkill for what you want.
First you are changing 82202 which is listed as a 750CX to be
reported as a 750CXe. Second, why not just add in the one case for
00083311 which is missing. Finally, we shouldn't put the revision
info into the cpu_name unless it actually matters. Seeing as the
cpu_features fields are all the same for all 750CXe parts there is no
need to distinguish them, we only need to ensure a match occurs.
Your patch really should be something like:
+ { /* 750CXe rev 3.1 */
+ .pvr_mask = 0xffff0fff,

* [PATCH] powerpc: merge semaphore.h
From: Becky Bruce @ 2005-09-23 16:07 UTC (permalink / raw)
To: linuxppc64-dev, linuxppc-dev
powerpc: Merge semaphore.h
Adopted the ppc64 version of semaphore.h. The 32-bit version used
smp_wmb(), but recent updates to atomic.h mean this is no longer required.
The 64-bit version made use of unlikely(), which has been retained in the
combined version.
This patch requires the recent atomic.h patch.

Paul,
I have a big patch that moves arch/ppc/math-emu to arch/powerpc/math-
emu and fixes up the arch/ppc/Makefile. How do you want me to send
this to you since its too big for the list or can you just make this
change since its:
1. git rename arch/ppc/math-emu arch/powerpc/math-emu
2. fixup arch/ppc/Makefile so:
core-$(CONFIG_MATH_EMULATION) += arch/powerpc/math-emu/
Let me know.

Hi.
First off, I've included the linuxppc-embedded mailing list in my
reply. It's better to mail the list and CC: me rather than just
mailing me. There are many others far brighter than me on the list
who can provide far more help.

Are you refering to the bit about device drivers registering to the
SPI subsystem? If so, the first patch provides the generic SPI
infrastructure. Device drivers for SPI masters and SPI slaves
register to the SPI subsystem. That way SPI master device drivers are
decoupled from SPI slave device drivers. It follows the new device
model in the 2.6.x kernels. (See "Linux Device Drivers" book from
O'reilly for details.

I've made no changes since posting the patch.
Eventually I'll have a public git tree with all my changes posted in
it; but not yet.
> How can I contribute to this effort?
Write code, write documentation and post patches. Also, look in the
LKML archives. There are two other competing SPI implementations that
are being developed. I've been pulled off onto other work so I've not
done any additional work. The other code looks more promising.
That being said, my code works for me so it may be usable for you as-is.
cheers,
g.

We're working on this. It's not exactly that simple since Jeff
established that all net drivers must enter through the netdev
tree. I expect it can get merged post 2.6.14 if all goes well.

Can you rebase off of Eugene's tree and resend patches? For the moment
the new EMAC driver is the lynchpin in anything new PPC4xx. I want
to hold off merging anything that involves current EMAC driver changes
until the new driver is in. In any case, nothing like this can go upstream
until after 2.6.14 is released. We are expecting the new EMAC driver to
be merged at that point. If you have this stuff rebased from his tree
we can easily merge them post-EMAC merge.

Please change these new files to ppc440spe.*. After the new EMAC
driver is merged, we are planning a Great Renaming(tm) to make the current

* [PATCH] powerpc: merged asm/cputable.h
From: Kumar Gala @ 2005-09-23 19:08 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev, arnd, linuxppc64-dev
Merged cputable.h between ppc32 and ppc64. In doing this removed support
for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they
dont compile correctly. C code should use cpu_has_feature(). This is
based on Arnd Bergmann's initial patch.

Jeff may want all net drivers to go through his tree, but with all due
respect to him, there's no law that says it has to be so.

I've already sent patches to Eugene that are in his EMAC tree. So his
driver will support 440SPe and can be merged before or after my
patches. If it's before then just dump my ibm_emac patch on the floor.

Okey-doke, will do.
