Convert all uses of error_report("warning:"... to use warn_report() instead. This helps standardise on a single method of printing warnings to the user. All of the warnings were changed using these two commands: find ./* -type f -exec sed -i \ 's|error_report(".*warning[,:] |warn_report("|Ig' {} + Indentation fixed up manually afterwards. The test-qdev-global-props test case was manually updated to ensure that this patch passes make check (as the test cases are case sensitive).

2017-05-11numa: equally distribute memory on nodesLaurent Vivier1-0/+2
When there are more nodes than available memory to put the minimum allowed memory by node, all the memory is put on the last node. This is because we put (ram_size / nb_numa_nodes) & ~((1 << mc->numa_mem_align_shift) - 1); on each node, and in this case the value is 0. This is particularly true with pseries, as the memory must be aligned to 256MB. To avoid this problem, this patch uses an error diffusion algorithm [1] to distribute equally the memory on nodes. We introduce numa_auto_assign_ram() function in MachineClass to keep compatibility between machine type versions. The legacy function is used with pseries-2.9, pc-q35-2.9 and pc-i440fx-2.9 (and previous), the new one with all others. Example: qemu-system-ppc64 -S -nographic -nodefaults -monitor stdio -m 1G -smp 8 \ -numa node -numa node -numa node \ -numa node -numa node -numa node Before: (qemu) info numa 6 nodes node 0 cpus: 0 6 node 0 size: 0 MB node 1 cpus: 1 7 node 1 size: 0 MB node 2 cpus: 2 node 2 size: 0 MB node 3 cpus: 3 node 3 size: 0 MB node 4 cpus: 4 node 4 size: 0 MB node 5 cpus: 5 node 5 size: 1024 MB After: (qemu) info numa 6 nodes node 0 cpus: 0 6 node 0 size: 0 MB node 1 cpus: 1 7 node 1 size: 256 MB node 2 cpus: 2 node 2 size: 0 MB node 3 cpus: 3 node 3 size: 256 MB node 4 cpus: 4 node 4 size: 256 MB node 5 cpus: 5 node 5 size: 256 MB [1] https://en.wikipedia.org/wiki/Error_diffusion Signed-off-by: Laurent Vivier <lvivier@redhat.com> Message-Id: <20170502162955.1610-2-lvivier@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> [ehabkost: s/ram_size/size/ at numa_default_auto_assign_ram()] Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2017-05-10pc/fwcfg: unbreak migration from qemu-2.5 and qemu-2.6 during firmware bootIgor Mammedov1-0/+1
Since 2.7 commit (b2a575a Add optionrom compatible with fw_cfg DMA version) regressed migration during firmware exection time by abusing fwcfg.dma_enabled property to decide loading dma version of option rom AND by mistake disabling DMA for 2.6 and earlier globally instead of only for option rom. so 2.6 machine type guest is broken when it already runs firmware in DMA mode but migrated to qemu-2.7(pc-2.6) at that time; a) qemu-2.6:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport) b) qemu-2.7:pc2.6 (fwcfg.dma=off,firmware=ioport,oprom=ioport) to: a b from a OK FAIL b OK OK So we currently have broken forward migration from qemu-2.6 to qemu-2.[789] that however could be fixed for 2.10 by re-enabling DMA for 2.[56] machine types and allowing dma capable option rom only since 2.7. As result qemu should end up with: c) qemu-2.10:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport) to: a b c from a OK FAIL OK b OK OK OK c OK FAIL OK where forward migration from qemu-2.6 to qemu-2.10 should work again leaving only qemu-2.[789]:pc-2.6 broken.

2016-07-04xen: fix ram init regressionGerd Hoffmann1-22/+28
Commit "8156d48 pc: allow raising low memory via max-ram-below-4g option" causes a regression on xen, because it uses a different memory split. This patch initializes max-ram-below-4g to zero and leaves the initialization to the memory initialization functions. That way they can pick different default values (max-ram-below-4g is zero still) or use the user supplied value (max-ram-below-4g is non-zero). Also skip the whole ram split calculation on Xen. xen_ram_init() does its own split calculation anyway so it is superfluous, also this way xen_ram_init can actually see whenever max-ram-below-4g is zero or not.

That way legacy firmware that doesn't use QEMU generated ACPI tables will be able to continue using legacy CPU hotplug interface. While new machine type, with firmware supporting QEMU provided ACPI tables, will generate new CPU hotplug AML, which will switch to new CPU hotplug interface when guest OS executes its _INI method on ACPI tables loading.

2016-06-06pc: allow raising low memory via max-ram-below-4g optionGerd Hoffmann1-22/+39
This patch extends the functionality of the max-ram-below-4g option to also allow increasing lowmem. Use case: Give as much memory as possible to legacy non-PAE guests. While being at it also rework the lowmem calculation logic and add a longish comment describing how it works and what the compatibility constrains are. Note: This is a incompatible change. When setting max-ram-below-4g to a value larger than 3.5G (or 3G with gigabyte alignment) it has no effect on older qemu versions: qemu silently ignores it. With the patch applied it actually has an effect and changes the ram layout. Highly unlikely to hit in practive though as there is no reason start old qemu versions that way.

2016-01-13isa: Clean up error handling around isa_bus_new()Markus Armbruster1-1/+2
We can have at most one ISA bus. If you try to create another one, isa_bus_new() complains to stderr and returns null. isa_bus_new() is called in two contexts, machine's init() and device's realize() methods. Since complaining to stderr is not proper in the latter context, convert isa_bus_new() to Error. Machine's init(): * mips_jazz_init(), called from the init() methods of machines "magnum" and "pica" * mips_r4k_init(), the init() method of machine "mips" * pc_init1() called from the init() methods of non-q35 PC machines * typhoon_init(), called from clipper_init(), the init() method of machine "clipper" These callers always create the first ISA bus, hence isa_bus_new() can't fail. Simply pass &error_abort.

2015-12-17kvm: x86: add support for KVM_CAP_SPLIT_IRQCHIPPaolo Bonzini1-2/+2
This patch adds support for split IRQ chip mode. When KVM_CAP_SPLIT_IRQCHIP is enabled: 1.) The PIC, PIT, and IOAPIC are implemented in userspace while the LAPIC is implemented by KVM. 2.) The software IOAPIC delivers interrupts to the KVM LAPIC via kvm_set_irq. Interrupt delivery is configured via the MSI routing table, for which routes are reserved in target-i386/kvm.c then configured in hw/intc/ioapic.c 3.) KVM delivers IOAPIC EOIs via a new exit KVM_EXIT_IOAPIC_EOI, which is handled in target-i386/kvm.c and relayed to the software IOAPIC via ioapic_eoi_broadcast.

2015-12-17qapi: Don't let implicit enum MAX member collideEric Blake1-1/+1
Now that we guarantee the user doesn't have any enum values beginning with a single underscore, we can use that for our own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious that the sentinel is generated. This patch was mostly generated by applying a temporary patch: |diff --git a/scripts/qapi.py b/scripts/qapi.py |index e6d014b..b862ec9 100644 |--- a/scripts/qapi.py |+++ b/scripts/qapi.py |@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = { | max_index = c_enum_const(name, 'MAX', prefix) | ret += mcgen(''' | [%(max_index)s] = NULL, |+// %(max_index)s | }; | ''', | max_index=max_index) then running: $ cat qapi-{types,event}.c tests/test-qapi-types.c | sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list $ git grep -l _MAX | xargs sed -i -f list The only things not generated are the changes in scripts/qapi.py.

2015-11-04pc: Set hw_version on all machine classesEduardo Habkost1-0/+13
In 2012, QEMU had a bug where it exposed QEMU version information to the guest, meaning a QEMU upgrade would expose different hardware to the guest OS even if the same machine-type is being used. The bug was fixed by commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4, on all machines up to pc-1.0. But we kept introducing the same bug on all newer machines since then. That means we are breaking guest ABI every time QEMU was upgraded. Fix this by setting the hw_version on all PC machines, making sure the hardware won't change when upgrading QEMU. Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU 1.1.0, it started following the "x.y.0" pattern. We have to follow it, to make sure we use the right QEMU_VERSION string from each QEMU release. The 2.5 machine classes could have hw_version unset, because the default value for qemu_get_version() is QEMU_VERSION. But I decided to set it explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0" after we release 2.5.0 and create a 2.6 machine class.
