Hi all,

Here is attached the patch to uptdate lvm structures in ioctl32.c
(arch/parisc/kernel).

Can somebody check in for me.

I check it (Ok) for 32bit kernel on my b180l.

Patrick,

Don't you see anything else to verify?

Bruno,

Could you see if it compiles now well for 64bits.

Thanks in advance for all,
    Joel

Looks good to me. I patched it in and then diffed it against the sparc64 one and
there were no LVM differences.

[-- Attachment #1: Type: text/plain, Size: 2226 bytes --]

	Hi
I've started this morning to download latest CVS bits.
I've prepared a patche for this version from my dump driver,
and try to recompile everything, but I've found a problem
with LVM !!! See:
make dep: okay
make vmlinux:
ioctl32.c:2009: warning: assignment makes pointer from integer without a cast
ioctl32.c:2030: structure has no member named `inode'
ioctl32.c:2049: warning: passing arg 2 of `lcopy_from_user' makes pointer from integer without a cast

ioctl32.c:2086: structure has no member named `inode'
ioctl32.c:1985: warning: `v' might be used uninitialized in this function 

-> in this file it is:
	v->pv[i]->pe = NULL; v->pv[i]->inode = NULL;
and
	p.pe = NULL; p.inode = NULL; 

It complains that there is no "inode" in structure pv[i].
So in this line v is a struct vg_t. In this structure
pv[i] is a pv_t structure, I've found this struture in
include/linux/lvm.h, and it is right, there is no "inode", 
in it !!!! Is this LVM code broken ?

Does LVM work on 64bit HP ?

I remember doing the ioctl32.c support for sparc64 some time ago but I can
easily beleive that the mods to that file haven't been propogated to other
32/64bit systems - if you're feeling adventurous and really need LVM then you
might be able to cut out those bits and drop them into the HP.

On the other hand you could try LVM2. I know LVM2 runs well on my 32bit HP
machines and also on 64bit Alpha.

Re: [parisc-linux] Probleme while compiling last CVS kernel.

[joel.soete]

Hi all,

I do not have the opportunity to run a 64bits kernel but for 32bits kernel I run
a patched kernel with last stable lvm-1.0.4 (and it is runing fine for at least
two month).
Humm which CONFIG_ parameter do I have to check to compile this src for 64-bits
kernel.
I can so try to see at least if it compiles well and report results.

I don't know about the 64bit compile switches (I only have a 32bit HP box) but
to get LVM running you'll need to take all the bits from
arch/sparc64/kernel/ioctl32.c inside the 

#if defined(CONFIG_BLK_DEV_LVM) || defined(CONFIG_BLK_DEV_LVM_MODULE)

#endif

and replace the bits from arch/parisc/kernel/ioctl32.c with them. I suspect it
will work. If it does then get a patch together and put it into the CVS !

I'm pleased (though not very surprised) that LVM works OK on 32 bit machines.

Well, a little. I've seen enough porting problems in my time that it always 
suprises me a little when a recompile on an untested platform "just works" !

Not anymore, in fact all seems already include in ioctl32.

So I just have to find how to compile a 64bits kernel. There should it be some
hack to bring it works.

See you later,

The stuff that's in there is for LVM0.8, whereas LVM 1.0 is in the rest of the
kernel. The structures have changed slightly which is why it won't compile ATM.

Ok I will have a more detailed look so.
