This patch series implements two optimizations: 1) transfer pages in chuncks between the guest and host; 2) transfer the guest unused pages to the host so that they can be skipped to migrate in live migration. Changes: v8->v9: 1) Split the two new features, VIRTIO_BALLOON_F_BALLOON_CHUNKS and VIRTIO_BALLOON_F_MISC_VQ, which were mixed together in the previous implementation; 2) Simpler

This patch set contains two parts of changes to the virtio-balloon. One is the change for speeding up the inflating & deflating process, the main idea of this optimization is to use bitmap to send the page information to host instead of the PFNs, to reduce the overhead of virtio data transmission, address translation and madvise(). This can help to improve the performance by about 85%.

Hi ! I've been trying to improve NV50 shader generation a bit the last couple of weeks, so here is what I've produced. I don't know if it's usable for you or just a pile of horrible hacks, but at least it makes some mesa demos render more correcly, p.e. the teapot (aside from mip-mapping issues of the floor texture), arbfplight, and I think the gears also didn't appear as they

Various changes/fixes to use smaller stack frames. Rich.
