Hi folks, I've finished off Xen dma support for pv_ops, and dom0 now boots! I've had an uptime of 40 minutes so far with it. Under intensive disk load it locks up with a soft lockup, but still, this is good progress. I've pushed the current bits to the "WIP" (work-in-progress) branch at the usual git repo, git://et.redhat.com/linux-2.6-dom0-pvops.git with gitweb at http://git.et.redhat.com/?p=linux-2.6-dom0-pvops.git New since the last drop are some MTRR cleanups from Mark McLoughlin, a number of dma-mapping cleanups, and full dma_alloc/free_coherent support, including xen contiguous mapping support. I've also updated it to Linus' final v2.6.24. The APIC code is still non-pvops-friendly, but other than that, all the new code is completely pvops-friendly and will work happily on baremetal as well as Xen. So next job is to clean up the xen contiguous-region support (split it up, update the calls to use cleaner, pvops virt/mfn/pfn macros, and use Jeremy's per-cpu pvops multicall batching), and to redo much of the APIC code to work properly with pvops. But in its current state it's useful enough for testing that I've pushed it as it stands. NOTE: this current code has not actually been tagged and rebased, it's not exactly a "release" as much as a snapshot of the development work --- I'll do a rebase and patchqueue release of it once I've done the contig region cleanups. I've also got paravirt framebuffer patches from Markus Armbruster to integrate for that. --Stephen _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
