[parisc-linux] 2.4.23 PCI source inconsistency

[parisc-linux] 2.4.23 PCI source inconsistency

[northern snowfall]

Hey all,
    I compiled 2.4.23 from kernel.org for 32bit PA-RISC today
and found that the PA-RISC specific PCI code seems to be out-
of sync with the generic pci code.

from arch/parisc/kernel/pci.c:

gcc -D__KERNEL__ -I/usr/home/north_/k/linux-2.4.23/include -Wall 
-Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common 
-fomit-frame-pointer -D__linux__ -pipe -fno-strength-reduce 
-mno-space-regs -mfast-indirect-calls -mdisable-fpregs 
-ffunction-sections -march=2.0 -mschedule=8000   -nostdinc -iwithprefix 
include -DKBUILD_BASENAME=pci  -c -o pci.o pci.c
pci.c: In function `pcibios_init_bus':
pci.c:310: structure has no member named `bridge_ctl'
pci.c:311: structure has no member named `bridge_ctl'
pci.c:312: structure has no member named `bridge_ctl'
pci.c:315: structure has no member named `bridge_ctl'
make[1]: *** [pci.o] Error 1

Of course, the pci_bus structure is declared in the header
include/linux/pci.h:/^struct.*pci_bus However, there is
no longer a bridge_ctl member.

I'm running 2.4.17 off the Debian 3.0 release on a B2000,
and /usr/include/linux/pci.h still has the bridge_ctl
member in the pci_bus structure.

Advice?

Thanks,
Don (north_)

Use cvs.parisc-linux.org.

As carlos said, use kernels from ftp.parisc-linux.org or pull
sources directly from cvs.parisc-linux.org.

I added this field to clean up FBB and VGA routing support.
"bridge_ctl" is a PCI-PCI Bridge register that controls
both of those behaviors. Ivan K. (ex PCI Maintainer) and I had it
working for parisc/ia32/alpha but apperently it never got
submitted/accepted into any official tree.

Russell King (ARM maintainer) found it useful anyway
and submitted it

	http://www.ussg.iu.edu/hypermail/linux/kernel/0208.0/0723.html

and later:
	http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2003-October/017459.html

Darn...looks like bridge_ctl didn't get pushed into 2.6 either. :^(
I'll follow up a bit offline.
