[PATCH] qemu: block: Always enable discard forwarding for 'throttle' filter layer

From: Peter Krempa Discards ought to be forwarded to the protocol nodes where we control if discard actually happens. Unconditionally enable discard='unmap' for the intermediate layer. Closes: https://gitlab.com/libvirt/libvirt/-/issues/810 Signed-off-by: Peter Krempa --- src/qemu/qemu_block.

[PATCH v6 0/8] qemu: acpi-generic-initiator support

= Overview = This patch set introduces support for acpi-generic-initiator devices, supported by QEMU [1]. The acpi-generic-initiator object is required to support Multi-Instance GPU (MIG) configurations on NVIDIA GPUs [2]. MIG enables partitioning of GPU resources into multiple isolated instances

[PATCH 7/8] docs: Document acpi nodeset in hostdev

Add documentation for the new element in hostdev, which allows associating devices with ACPI Generic Initiator objects in QEMU. A typical use case is NVIDIA Multi-Instance GPU (MIG), where a physical GPU is partitioned into multiple isolated instances, each tied to one or more virtual NUMA nodes.

[PATCH 2/8] qemu: Allow to define NUMA nodes without memory or CPUs assigned

Allow to define NUMA nodes without memory or CPUs assigned to properly support the new acpi-generic-initiator device. This is required because the NUMA nodes passed to the acpi-generic-initiator object must be independent and not be shared with other resources, such as CPU or memory. Signed-off-b
