2019-05-20virtio: Introduce started flag to VirtioDeviceXie Yongji1-0/+2
The virtio 1.0 transitional devices support driver uses the device before setting the DRIVER_OK status bit. So we introduce a started flag to indicate whether driver has started the device or not.

2019-05-20Revert "globals: Allow global properties to be optional"Daniel P. Berrangé1-3/+0
This reverts commit d7741743f4f3d2683d1bb6938f88dc0167c21afa. Relying on setting properties on parents types which may not be relevant to certain sub-classes had unexpected side-effects causing bugs in device config defaults. It is preferrable to be explicit about which devices get which properties, even if this needs repetition. Signed-off-by: Daniel P.

2019-05-17ioapic: allow buggy guests mishandling level-triggered interrupts to make ↵Vitaly Kuznetsov1-0/+3
progress It was found that Hyper-V 2016 on KVM in some configurations (q35 machine + piix4-usb-uhci) hangs on boot. Root-cause was that one of Hyper-V level-triggered interrupt handler performs EOI before fixing the cause of the interrupt. This results in IOAPIC keep re-raising the level-triggered interrupt after EOI because irq-line remains asserted. Gory details: https://www.spinics.net/lists/kvm/msg184484.html (the whole thread). Turns out we were dealing with similar issues before; in-kernel IOAPIC implementation has commit 184564efae4d ("kvm: ioapic: conditionally delay irq delivery duringeoi broadcast") which describes a very similar issue. Steal the idea from the above mentioned commit for IOAPIC implementation in QEMU. SUCCESSIVE_IRQ_MAX_COUNT, delay and the comment are borrowed as well.

When building with CONFIG_Q35=n, we get: LINK x86_64-softmmu/qemu-system-x86_64 /usr/bin/ld: hw/i386/acpi-build.o: in function `acpi_get_misc_info': /source/qemu/hw/i386/acpi-build.c:243: undefined reference to `ich9_lpc_find' collect2: error: ld returned 1 exit status make[1]: *** [Makefile:204: qemu-system-x86_64] Error 1 This is due to a dependency in acpi-build.c on the ICH9_LPC (via ich9_lpc_find) and PIIX4_PM (via piix4_pm_find) devices. To allow better modularity (compile acpi-build.c with only Q35/ICH9 or ISAPC/PIIX4), refactor the similar helper as object_resolve_type_unambiguous(). This way we relax the linker dependencies and can build the x86 targets with a selection of machines (instead of all of them).

2019-05-07hw/arm/virt: Support firmware configuration with -blockdevMarkus Armbruster1-0/+2
The ARM virt machines put firmware in flash memory. To configure it, you use -drive if=pflash,unit=0,... and optionally -drive if=pflash,unit=1,... Why two -drive? This permits setting up one part of the flash memory read-only, and the other part read/write. It also makes upgrading firmware on the host easier. Below the hood, we get two separate flash devices, because we were too lazy to improve our flash device models to support sector protection. The problem at hand is to do the same with -blockdev somehow, as one more step towards deprecating -drive. We recently solved this problem for x86 PC machines, in commit ebc29e1beab. See the commit message for design rationale. This commit solves it for ARM virt basically the same way: new machine properties pflash0, pflash1 forward to the onboard flash devices' properties. Requires creating the onboard devices in the .instance_init() method virt_instance_init(). The existing code to pick up drives defined with -drive if=pflash is replaced by code to desugar into the machine properties. There are a few behavioral differences, though: * The flash devices are always present (x86: only present if configured) * Flash base addresses and sizes are fixed (x86: sizes depend on images, mapped back to back below a fixed address) * -bios configures contents of first pflash (x86: -bios configures ROM contents) * -bios is rejected when first pflash is also configured with -machine pflash0=... (x86: bios is silently ignored then) * -machine pflash1=... does not require -machine pflash0=... (x86: it does). The actual code is a bit simpler than for x86 mostly due to the first two differences. Before the patch, all the action is in create_flash(), called from the machine's .init() method machvirt_init(): main() machine_run_board_init() machvirt_init() create_flash() create_one_flash() for flash[0] create configure includes obeying -drive if=pflash,unit=0 realize map fall back to -bios create_one_flash() for flash[1] create configure includes obeying -drive if=pflash,unit=1 realize map update FDT To make the machine properties work, we need to move device creation to its .instance_init() method virt_instance_init(). Another complication is machvirt_init()'s computation of @firmware_loaded: it predicts what create_flash() will do. Instead of predicting what create_flash()'s replacement virt_firmware_init() will do, I decided to have virt_firmware_init() return what it did. Requires calling it a bit earlier. Resulting call tree: main() current_machine = object_new() ... virt_instance_init() virt_flash_create() virt_flash_create1() for flash[0] create configure: set defaults become child of machine [NEW] add machine prop pflash0 as alias for drive [NEW] virt_flash_create1() for flash[1] create configure: set defaults become child of machine [NEW] add machine prop pflash1 as alias for drive [NEW] for all machine props from the command line: machine_set_property() ... property_set_alias() for machine props pflash0, pflash1 ... set_drive() for cfi.pflash01 prop drive this is how -machine pflash0=... etc set machine_run_board_init(current_machine); virt_firmware_init() pflash_cfi01_legacy_drive() legacy -drive if=pflash,unit=0 and =1 [NEW] virt_flash_map() virt_flash_map1() for flash[0] configure: num-blocks realize map virt_flash_map1() for flash[1] configure: num-blocks realize map fall back to -bios virt_flash_fdt() update FDT You have László to thank for making me explain this in detail.

2019-04-26spapr: Support NVIDIA V100 GPU with NVLink2Alexey Kardashevskiy2-1/+49
NVIDIA V100 GPUs have on-board RAM which is mapped into the host memory space and accessible as normal RAM via an NVLink bus. The VFIO-PCI driver implements special regions for such GPUs and emulates an NVLink bridge. NVLink2-enabled POWER9 CPUs also provide address translation services which includes an ATS shootdown (ATSD) register exported via the NVLink bridge device. This adds a quirk to VFIO to map the GPU memory and create an MR; the new MR is stored in a PCI device as a QOM link. The sPAPR PCI uses this to get the MR and map it to the system address space. Another quirk does the same for ATSD. This adds additional steps to sPAPR PHB setup: 1. Search for specific GPUs and NPUs, collect findings in sPAPRPHBState::nvgpus, manage system address space mappings; 2. Add device-specific properties such as "ibm,npu", "ibm,gpu", "memory-block", "link-speed" to advertise the NVLink2 function to the guest; 3. Add "mmio-atsd" to vPHB to advertise the ATSD capability; 4. Add new memory blocks (with extra "linux,memory-usable" to prevent the guest OS from accessing the new memory until it is onlined) and npuphb# nodes representing an NPU unit for every vPHB as the GPU driver uses it for link discovery. This allocates space for GPU RAM and ATSD like we do for MMIOs by adding 2 new parameters to the phb_placement() hook. Older machine types set these to zero. This puts new memory nodes in a separate NUMA node to as the GPU RAM needs to be configured equally distant from any other node in the system. Unlike the host setup which assigns numa ids from 255 downwards, this adds new NUMA nodes after the user configures nodes or from 1 if none were configured. This adds requirement similar to EEH - one IOMMU group per vPHB. The reason for this is that ATSD registers belong to a physical NPU so they cannot invalidate translations on GPUs attached to another NPU. It is guaranteed by the host platform as it does not mix NVLink bridges or GPUs from different NPU in the same IOMMU group. If more than one IOMMU group is detected on a vPHB, this disables ATSD support for that vPHB and prints a warning.

This patch fixes four different things, to maintain bisectability they have been merged into a single patch. The following fixes are below: sifive_plic: Fix incorrect irq calculation The irq is incorrectly calculated to be off by one. It has worked in the past as the priority_base offset has also been set incorrectly. We are about to fix the priority_base offset so first first the irq calculation. sifive_u: Fix PLIC priority base offset and numbering According to the FU540 manual the PLIC source priority address starts at an offset of 0x04 and not 0x00. The same manual also specifies that the PLIC only has 53 source priorities. Fix these two incorrect header files. We also need to over extend the plic_gpios[] array as the PLIC sources count from 1 and not 0. riscv: sifive_e: Fix PLIC priority base offset According to the FE31 manual the PLIC source priority address starts at an offset of 0x04 and not 0x00. riscv: virt: Fix PLIC priority base offset Update the virt offsets based on the newly updated SiFive U and SiFive E offsets.

2019-03-29spapr: Simplify handling of host-serial and host-model valuesDavid Gibson1-0/+1
27461d69a0f "ppc: add host-serial and host-model machine attributes (CVE-2019-8934)" introduced 'host-serial' and 'host-model' machine properties for spapr to explicitly control the values advertised to the guest in device tree properties with the same names. The previous behaviour on KVM was to unconditionally populate the device tree with the real host serial number and model, which leaks possibly sensitive information about the host to the guest. To maintain compatibility for old machine types, we allowed those props to be set to "passthrough" to take the value from the host as before. Or they could be set to "none" to explicitly omit the device tree items. Special casing specific values on what's otherwise a user supplied string is very ugly. So, this patch simplifies things by implementing the backwards compatibility in a different way: we have a machine class flag set for the older machines, and we only load the host values into the device tree if A) they're not set by the user and B) we have that flag set. This does mean that the "passthrough" functionality is no longer available with the current machine type. That's ok though: if a user or management layer really wants the information passed through they can read it themselves (OpenStack Nova already does something similar for x86). It also means the user can't explicitly ask for the values to be omitted on the old machine types. I think that's an acceptable trade-off: if you care enough about not leaking the host information you can either move to the new machine type, or use a dummy value for the properties. For the new machine type, this also removes an odd inconsistency between running on a POWER and non-POWER (or non-Linux) hosts: if the host information couldn't be read from where we expect (in the host's device tree as exposed by Linux), we'd fallback to omitting the guest device tree items. While we're there, improve some poorly worded comments, and the help text for the properties. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Daniel P.
