If the -mem-path option is set, we attempt to map the guest's RAM from a file in the given path; it's usually used to back guest RAM with hugepages. If we're unable to (e.g. not enough free hugepages) then we fall back to allocating normal anonymous pages. This behaviour can be surprising, but a

[Qemu-devel] [PATCH v3 13/35] spapr: add hcalls support for the XIVE exploitation interrupt mode

The different XIVE virtualization engines (sources and event queues) are configured with a set of Hypervisor calls : - H_INT_GET_SOURCE_INFO used to obtain the address of the MMIO page of the Event State Buffer (PQ bits) entry associated with the source. - H_INT_SET_SOURCE_CONFIG

[Qemu-devel] [PATCH v3 05/35] spapr/xive: add a single source block to the sPAPR XIVE model

Bare-metal systems (PowerNV) have multiples interrupt sources. The XIVE interrupt controller has an internal source for IPIs and generic IPIs, the PSIHB has one and also the PHBs. But, for simplicity on the sPAPR machine, we use a unique XiveSource object for all IPIs and virtual device interrupts

[Qemu-devel] [PATCH v3 27/35] migration: discard non-migratable RAMBlocks

On the POWER9 processor, the XIVE interrupt controller can control interrupt sources using MMIO to trigger events, to EOI or to turn off the sources. Priority management and interrupt acknowledgment is also controlled by MMIO in the presenter sub-engine. These MMIO regions are exposed to guests

[Qemu-devel] [PATCH v3 34/35] ppc/pnv: add XIVE support

This is simple model of the POWER9 XIVE interrupt controller for the PowerNV machine. XIVE for baremetal is a complex controller and the model only addresses the needs of the skiboot firmware. Support is provided for : * virtual structure descriptor tables describing the XIVE internal tables

[Qemu-devel] [PATCH v3 31/35] spapr/xive: raise migration priority of the machine

The XIVE MMIO regions should be set on the destination before the XIVE sources are restored. This is currently handled at the machine level because it depends on the KVM initialization to be done before anything else. But it has ugly consequences on MMU, which seems broken after migration :

[Qemu-devel] [PATCH 1/4] audio/hda: create millisecond timers that handle IO

Currently, the HDA device tries to sync itself with the QEMU audio backend by waiting for the guest driver to handle buffer completion interrupts. This causes the backend to often read too much data from the device, as well as running out of data whenever the guest takes too long to handle the

[Qemu-devel] [PATCH 1/4] ui: add qapi parser for -display

Add parse_display_qapi() function which parses the -display command line using a qapi visitor for DisplayOptions. Wire up as default catch in parse_display(). Improves the error message for unknown display types. Also enables json as -display argument, i.e. -display "{ 'type': 'gtk' }"

[Qemu-devel] [PATCH v2 03/43] configure: add support for --cross-cc-FOO
