Well, the debian 1.2.2-2 openafs-modules-source actually, but the
changes are mere cut&pasting; I'm forwarding them here as much to
report that they worked, as anything else. Files changed:
openafs/debian/sysname
- debian specific, just to admit the port exists
openafs/src/config/afs_sysnames.h
- allocate the next SYS_NAME_ID
openafs/src/config/Makefile.sparc_linux24.in
- unchanged copy of Makefile.sparc_linux22.in
openafs/src/config/param.sparc_linux24.h
- starting from param.sparc_linux22.h, set AFS_LINUX24_ENV,
AFS_SPARC_LINUX24_ENV, SYS_NAME, SYS_NAME_ID.
openafs/src/config/param.sparc_linux24_usr.h
- starting from param.sparc_linux22_usr.h, set
AFS_USR_LINUX24_ENV, SYS_NAME, SYS_NAME_ID.
Oh, and for completeness, I've included the patch needed to make
2.4.16 build at all on a sparc:
kernel-source-2.4.16/arch/sparc/kernel/traps.c
- Implement show_trace_task (snarf sparc64 version, drop
STACK_BIAS.)
Nothing momentous, it did handle writing 200M of build tree into one
volume without problems (other than the issue that an SS10 is slow
these days :-) Not what I'd call real testing, but perhaps enough to
justify including this configuration. Thanks.
