Hi, This patchset allows vhost to be used with legacy virtio when guest and host have a different endianness. Patch 7 got rewritten according to Cornelia's and Michael's comments. I have also introduced patch 8 that brings BE vnet headers support to tun/macvtap. This series is enough to have vhost_net working flawlessly. I could succesfully reboot guests from ppc64 to ppc64le and

Recently, I got many reports about perfermance degradation in embedded system(Android mobile phone, webOS TV and so on) and easy fork fail. The problem was fragmentation caused by zram and GPU driver mainly. With memory pressure, their pages were spread out all of pageblock and it cannot be migrated with current compaction algorithm which supports only LRU pages. In the end, compaction cannot

Recently, I got many reports about perfermance degradation in embedded system(Android mobile phone, webOS TV and so on) and failed to fork easily. The problem was fragmentation caused by zram and GPU driver pages. Their pages cannot be migrated so compaction cannot work well, either so reclaimer ends up shrinking all of working set pages. It made system very slow and even to fail to fork easily.
