From: "Maciej S. Szmigiero" <maciej.szmigi...@oracle.com> Hi Stefan,
Fixed the CI pipeline issues with yesterday's pull request, and: the following changes since commit d762bf97931b58839316b68a570eecc6143c9e3e: Merge tag 'pull-target-arm-20231102' of https://git.linaro.org/people/pmaydell/qemu-arm into staging (2023-11-03 10:04:12 +0800) are available in the Git repository at: https://github.com/maciejsszmigiero/qemu.git tags/pull-hv-balloon-20231106 for you to fetch changes up to 00313b517d09c0b141fb32997791f911c28fd3ff: MAINTAINERS: Add an entry for Hyper-V Dynamic Memory Protocol (2023-11-06 14:08:10 +0100) ---------------------------------------------------------------- Hyper-V Dynamic Memory protocol driver. This driver is like virtio-balloon on steroids for Windows guests: it allows both changing the guest memory allocation via ballooning and inserting pieces of extra RAM into it on demand from a provided memory backend via Windows-native Hyper-V Dynamic Memory protocol. * Preparatory patches to support empty memory devices and ones with large alignment requirements. * Revert of recently added "hw/virtio/virtio-pmem: Replace impossible check by assertion" commit 5960f254dbb4 since this series makes this situation possible again. * Protocol definitions. * Hyper-V DM protocol driver (hv-balloon) base (ballooning only). * Hyper-V DM protocol driver (hv-balloon) hot-add support. * qapi query-memory-devices support for the driver. * qapi HV_BALLOON_STATUS_REPORT event. * The relevant PC machine plumbing. * New MAINTAINERS entry for the above. ---------------------------------------------------------------- David Hildenbrand (2): memory-device: Support empty memory devices memory-device: Drop size alignment check Maciej S.
