I'd much prefer if we copied rather than moved it to asm-powerpc. I'm
hoping we can get rid of the remaining sharing of include files shared
between ppc and powerpc. That way we can do cleanups in powerpc
without worrying about breaking ppc. In turn that should expedite
progress towards ditching arch/ppc entirely.

* PCMCIA on ppc64, and the joys of io port ranges on mmio-only platforms
From: Olof Johansson @ 2007-05-10 0:32 UTC (permalink / raw)
To: linuxppc-dev, linux-kernel, linux-pcmcia
Hi,
We've got a very simple CF interface on our eval board, sitting on
localbus with a couple of gpios for control. mem and i/o port ranges
are mapped to two mmio ranges, i.e. 0xf0000000 and 0xf1000000 in our case.
I've got a pcmcia driver for the slot to handle all the probing, etc. It ioremaps both
the mem and io ranges, and provides that with the registered device:
cf->mem_base = ioremap(mem->start, mem->end - mem->start);
cf->io_base = ioremap(io->start, io->end - io->start);
[...]
/* pcmcia layer only remaps "real" memory not iospace */
cf->socket.io_offset = (unsigned long)cf->io_base;
/* reserve chip-select regions */
if (!request_mem_region(mem->start, mem->end + 1 - mem->start,
[...]
if (!request_mem_region(io->start, io->end + 1 - io->start, driver_name))
[...]
cf->socket.dev.parent = &ofdev->dev;
cf->socket.ops = &electra_cf_ops;
cf->socket.resource_ops = &pccard_static_ops;
cf->socket.features = SS_CAP_PCCARD | SS_CAP_STATIC_MAP | SS_CAP_MEM_ALIGN;
[...]
(I'll post the full driver separately, but wanted to bring this up first).
Bottom line is that io_offset points to the ioremap()ed memory, i.e a
64-bit kernel address.
The problems show up further up the stack, in this case in the
pata_pcmcia driver, where pcmcia_request_io() is used to handle the
address allocation. That in turn calls alloc_io_space(), which takes an
ioaddr_t * as argument and does math on it.
ioaddr_t is 32-bit, causing obvious problems since io_offset is
64-bit. There's a compatible kio_addr_t available, but I'm guessing it's
already not used because of ABI requiremenets given the big warning at
the definition of ioaddr_t.
Since ppc64 never has had pcmcia before (We're the first platform with
it), changing the type under ifdef like mips/arm shouldn't be a problem,
at least it won't lead to regressions -- there's no previous user apps
to regress.
However, that's not enough in this case: Next thing that will fail is
ioport_map() in ppc-specific code, called from devm_ioport_map(). It
currently assumes to be passed the bus-local port number and adding
it to the ioremap base of the (normally only) bus with I/O ports,
i.e. ISA/LPC. Since we already use that for other devices (UARTS, etc),
we now have more than one base register.
I see two ways to solve this:
1. Create infrastructure to track the various io-port ranges, register
them and let the infrastructure take care of the ioremap, pick the right
ioport_map(), etc. I.e. create virtual io port ranges.
2. Make ioport_map() detect already mapped arguments (i.e.:
+ if (port >= IMALLOC_BASE && (port+len) < IMALLOC_END)
+ return (void __iomem *)port;
(1) would be appealing if it was the only change needed, and if that
meant that I didn't have to change ioaddr_t. It doesn't though, since
the pcmcia code still stores the ioport_map():ed value in an ioaddr_t,
so it really just adds complexity without that much benefit.
I'm tempted to go with (2) + type change but if someone has a third
option I'm all ears.

get_property() got renamed to of_get_property().
You have two coding-styles in the typecasting here. The former (no space)
is more common and makes more sense, IMO.
However of_get_property() returns const void* so really you shouldn't be
doing any casting at all. `model' should have type `const char *' and then
you can do
model = get_property(np, "model", NULL);
which has nice type-safety and const-correctness.

Sorry, I've been busy with other things...
What do other thing about it ? Having update_mmu_cache() call buried
inside the ptep_set_access_flags() sounds good ? Somebody has a better
idea ?
One thing I was thinking was that we could replace the whole logic with
having ptep_set_access_flags() compare the new PTE bits with what was
already there and return wether an update_mmu_cache() is required....

May I ask to point to the code you're keeping in mind here?
I'm not going to touch this path or else the code will miss this merge window as well,
but I'm going to keep improving it, and this rework might be useful not only for this particular driver,
but for similar kernel pieces too.

Hi Ben,
Is it worth formally sending in either of my patches or does more work
need to be done first?
If you would like me to test any changes, it takes me app. 2 hours to
cross-compile a sparc kernel for my sun4c. I use my sparc system as a
diskless client with a very minimal setup to alow me to test cross
compiled GCC and any small platform independent code I may be working on.
I have not yet tried to get linux-2.6.21 or later working but for the test
setup I have been using, it should not take too long if that is the kernel
needed for testing.
I may also be able to do the same testing on an embedded PowerPC (32bit)
(it will need some work to get my cross compilation system working again
as some kernel changes in the ppc/powerpc architechture have proven to be
incompatible with my build scripts) and on x86_64/ix86. Once I have fixed
the build scripts, it will take app. 4 to 6 hours to get the initial NFS
root minimal system built for these additional architectures and then app.
2 hours for each test kernel build.
If a simple ADA build is not considered a suficiently harsh test, then I
could cross compile a specialist test application, if one is available, or
compile a more extensive application (maybe gcc) on the test system. The
problem of compiling a more extensive application on the sparc system is
that it is a slow system running as a diskless client with its NFS root on
an aging i486 over a 10MBit Ethernet. The result is it will take days to
compile somthing like gcc.

Mark Fortescue

Thus requiring the driver to maintain a list of models/compatibles for
every possible combination of features, rather than letting the device

I find these 50 or so warnings so scary that I've not yet tried
to boot the kernel. Note that this is a non-modular kernel.

Should be already fixed in Paulus' latest tree (and in Linus' tree after

* Build failure with Linus' tree
From: Ken Moffat @ 2007-05-09 16:17 UTC (permalink / raw)
To: linuxppc-dev
On my G5 I'm getting this on a copy of Linus' tree I pulled a bit
over two hours ago:
LD .tmp_vmlinux1
arch/powerpc/sysdev/built-in.o: In function `.iommu_init_late_dart':
dart_iommu.c:(.init.text+0xf10): undefined reference to
`.register_nosave_region_late'
make: *** [.tmp_vmlinux1] Error 1
I suppose that something is wrong in sysdev/dart_iommu.c, probably
related to suspend changes - if I need to bisect, it will take some
time (this is an SMU powermac, dead slow) so I'll mention it here
now.

My preference is to split them like this so that the architectures that
don't need the compat infrastructure are not cluttered with it (if we
declare the compat routines in syscalls.h, then it should include
compat.h).
