2020-11-23vfio: Change default dirty pages tracking behavior during migrationKirti Wankhede1-0/+1
By default dirty pages tracking is enabled during iterative phase (pre-copy phase). Added per device opt-out option 'x-pre-copy-dirty-page-tracking' to disable dirty pages tracking during iterative phase. If the option 'x-pre-copy-dirty-page-tracking=off' is set for any VFIO device, dirty pages tracking during iterative phase will be disabled.

2020-11-23vfio: Make migration support experimentalAlex Williamson1-0/+1
Support for migration of vfio devices is still in flux. Developers are attempting to add support for new devices and new architectures, but none are yet readily available for validation. We have concerns whether we're transferring device resources at the right point in the migration, whether we're guaranteeing that updates during pre-copy are migrated, and whether we can provide bit-stream compatibility should any of this change. Even the question of whether devices should participate in dirty page tracking during pre-copy seems contentious. In short, migration support has not had enough soak time and it feels premature to mark it as supported. Create an experimental option such that we can continue to develop.

2020-11-18s390x/pci: fix endianness issuesCornelia Huck1-4/+4
The zPCI group and function structures are big endian. However, we do not consistently store them as big endian locally, and are missing some conversions. Let's just store the structures as host endian instead and convert to big endian when actually handling the instructions retrieving the data. Also fix the layout of ClpReqQueryPciGrp: g is actually only 8 bit. This also fixes accesses on little endian hosts, and makes accesses on big endian hosts consistent.

2020-11-13intc/ibex_plic: Ensure we don't loose interruptsAlistair Francis1-0/+1
If an interrupt occurs between when we claim and complete an interrupt we currently drop the interrupt in ibex_plic_irqs_set_pending(). This somewhat matches hardware that also ignore the interrupt between the claim and complete process. In the case of hardware though the physical interrupt line will still be asserted after we have completed the interrupt. This means we will still act on the interrupt after the complete process. In QEMU we don't and instead we drop the interrupt as it is never recorded. This patch changed the behaviour of the Ibex PLIC so that we save all interrupts that occur while we are between claiming and completing an interrupt so that we can act on them after the completition process. This fixes interrupts being dropped when running Tock on OpenTitain in QEMU.

2020-11-13hmp: Pass monitor to mon_get_cpu_env()Kevin Wolf1-1/+1

2020-11-03Revert "vhost-blk: set features before setting inflight feature"Stefan Hajnoczi1-1/+0
This reverts commit adb29c027341ba095a3ef4beef6aaef86d3a520e. The commit broke -device vhost-user-blk-pci because the vhost_dev_prepare_inflight() function it introduced segfaults in vhost_dev_set_features() when attempting to access struct vhost_dev's vdev pointer before it has been assigned. To reproduce the segfault simply launch a vhost-user-blk device with the contrib vhost-user-blk device backend: $ build/contrib/vhost-user-blk/vhost-user-blk -s /tmp/vhost-user-blk.sock -r -b /var/tmp/foo.img $ build/qemu-system-x86_64 \ -device vhost-user-blk-pci,id=drv0,chardev=char1,addr=4.0 \ -object memory-backend-memfd,id=mem,size=1G,share=on \ -M memory-backend=mem,accel=kvm \ -chardev socket,id=char1,path=/tmp/vhost-user-blk.sock Segmentation fault (core dumped) Cc: Jin Yu <jin.yu@intel.com> Cc: Raphael Norwitz <raphael.norwitz@nutanix.com> Cc: Michael S.

The device tree file includes the description for the I2C1 node hence kernel tries to probe the I2C1 device during boot. It is enough to create an unimplemented device for I2C1 to allow the kernel to continue booting to the shell.

2020-11-03hw/riscv: microchip_pfsoc: Correct DDR memory mapBin Meng1-1/+4
When system memory is larger than 1 GiB (high memory), PolarFire SoC maps it at address 0x10_0000_0000. Address 0xC000_0000 and above is aliased to the same 1 GiB low memory with different cache attributes. At present QEMU maps the system memory contiguously from 0x8000_0000. This corrects the wrong QEMU logic. Note address 0x14_0000_0000 is the alias to the high memory, and even physical memory is only 1 GiB, the HSS codes still tries to probe the high memory alias address. It seems there is no issue on the real hardware, so we will have to take that into the consideration in our emulation. Due to this, we we increase the default system memory size to 1537 MiB (the minimum required high memory size by HSS) so that user gets notified an error when less than 1537 MiB is specified.

Currently, it's only use by the next patch in qemu-ga, which doesn't (well well...) need the thread safety guarantees. Since the fallback version is still unsafe, I would rather keep the _qemu postfix, to make sure it's not being misused by mistake.

2020-11-02hw/intc/arm_gicv3_cpuif: Make GIC maintenance interrupts workPeter Maydell1-1/+0
In gicv3_init_cpuif() we copy the ARMCPU gicv3_maintenance_interrupt into the GICv3CPUState struct's maintenance_irq field. This will only work if the board happens to have already wired up the CPU maintenance IRQ before the GIC was realized. Unfortunately this is not the case for the 'virt' board, and so the value that gets copied is NULL (since a qemu_irq is really a pointer to an IRQState struct under the hood). The effect is that the CPU interface code never actually raises the maintenance interrupt line. Instead, since the GICv3CPUState has a pointer to the CPUState, make the dereference at the point where we want to raise the interrupt, to avoid an implicit requirement on board code to wire things up in a particular order.
