Ok I finished now my asm optimized rwsemaphores and I improved a little my
spinlock based one but without touching the icache usage.
Here it is the code against pre6 vanilla:
ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/patches/v2.4/2.4.4pre6/rwsem-8
here the same but against David's try#2:
and here again the same but against David's latest try#3:
The main advantage of my rewrite are:
- my x86 version is visibly faster than yours in the write fast path and it
also saves icache because it's smaller (read fast path is reproducibly a bit faster too)
- my spinlock version is visibly faster in both read and write fast path and still
has smaller icache footprint (of course my version is completly out of line too
and I'm comparing apples to apples)
- at least to me the slow path of my code seems to be much simpler
than yours (and I can actually understand it ;), for example I don't feel
any need of any atomic exchange anywhere, I admit now comparing
my code to yours I still don't know why you need it
- the common code automatically extends itself to support 2^32 concurrent sleepers
on 64bit archs
- there is no code duplication at all in supporting xchgadd common code logic
for other archs (and I prepared a skeleton to fill for the alpha)
Only disavantage is that sparc64 will have to fixup some bit again.
Here the numbers of the above patches on top of vanilla 2.4.4-pre6:
----------------------------------------------

I draw a graph with the above numbers compared to the previous quoted numbers I
generated a few hours ago with your latest try#3 (attached). (W1 and R1 are
respectively the benchmark of the write fast path and read fast path, only one
writer and only one reader and they're of course the most interesting ones)
So I'd suggest Linus to apply one of my above -8 patches for pre7. (I hope I
won't need any secondary try)
this is a diffstat of the rwsem-8 patch:
