(If it is not bisectable, it should be fixed).

Given that not all architecture maintainers read lkml, and they are patches affecting all *architectures*, wouldn't it have been a good idea if they'd copied linux-arch? -- Russell King Linux kernel2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: - 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/

What would be good is if some effort could be made by the utrace- interested parties to make the transition to utrace much less painful. For instance, I quite like the getregs/setregs abstractions, and it looks like these *could* be self-contained in a single patch. It would be nice if we could move architectures over to this one a time. Once that's in, that's one chunk of utrace merged. -- Russell King Linux kernel2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: - 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 don't think a utrace merge as in one big merge is going to happen ever. It's just a too big patch doing too many things at once. And the flag day for switching all architectures over is another blocker. - 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/

There's a lot of review work to be done here, and a lot of it by busy architecture maintainers. Expecting people to do all this review and test work late in the merge window when they're all madly scrambling to get their bugs^Wpatches into mainline is not reasonable. This should all have started a month ago. So we're looking at a 2.6.25 merge for this work.

[PATCH 0/21] KGDB: Request to merge KGDB
This is a request to merge KGDB into the mainline kernel. These KGDB patches are against the tip of kernel of the tree on October 15, 2007. I am continuing to update the for_mm branch against the tip of the tree with the hope to merge KGDB into the kernel, pending the review of the individual pieces. http://git.kernel.org/?p=linux/kernel/git/jwessel/linux-2.6-kgdb.git;a=shortlog;h=for_mm As of right now KGDB is comprised of 21 different patches adding in the core api and docs first and then working up to add drivers and arch specific support to KGDB. The patches were broken down into logical pieces for review and comments. The intent of the KGDB patches is to unify the KGDB support across all the architectures that elect to implement it KGDB functionality by providing a common core and an arch specific stub. For quite some time there has been different features and uses of KGDB across the most popular architectures. Having a common core that takes care of protocol parsing and the typical use case of software breakpoints should eliminate the inconsistencies across the archs as well as making it easier to add KGDB support to a new arch. These KGDB patches include support for KGDB over ethernet and unify the syntax and usage for setting up kgdb over rs232. This series of KGDB patches covers the archs: i386, x86_64, ia64, arm, mips, sh, ppc and powerpc. After the merge of this patch set, any other arch can implement KGDB support in the future by making use of the KGDB core by updating the kgdb kconfig file and creating the arch specific stub.
