Hi, everybody I found two bugs in kgdb-ga-rt patch. The first one : if CONFIG_SMP is not set, we have a compile error The second one : if CONFIG_KGDB is not set, we have a link error I send you a diff patch to correct this. I am not sure the last patch is correct, but it works. The reported bugs are now rolled into the kgdb patch. Also, there is a new README.txt. I also included, in the kgdb patch, an updated gdb macro file (Documentation/i386/kgdb/gdbinit.hw) which has a per_cpu macro to: given a per_cpu structure name and the cpu number returns the address of that structure, properly typed. I am also putting my current version of time_stamp_tool. This is the replacement for kgdb_ts() which I have removed from the kgdb patch. Still a little rough but it has promise of being arch independent. -- George Anzinger george@mvista.com HRT (High-res-timers): http://sourceforge.net/projects/high-res-timers/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I also included, in the kgdb patch, an updated gdb macro file (Documentation/i386/kgdb/gdbinit.hw) which has a per_cpu macro to: given a per_cpu structure name and the cpu number returns the address of that structure, properly typed. I am also putting my current version of time_stamp_tool. This is the replacement for kgdb_ts() which I have removed from the kgdb patch.

Hi, everybody
I found two bugs in kgdb-ga-rt patch.
The first one : if CONFIG_SMP is not set, we have a compile error
The second one : if CONFIG_KGDB is not set, we have a link error
I send you a diff patch to correct this. I am not sure the last patch is

For the time being i wont add it to the -RT tree (because KGDB is not destined for upstream merging it seems), but it sure is a useful development/debugging add-on. I agree on not adding it. Tom Rini is working on a version the Andrew seems inclined to merge. When that happens I will most likely put together enhancements to it to bring it up to what this one does. Meanwhile I am trying to capture some of Tom's changes in this one.
