pc: acpi: generate AML only for PCI0 devices if PCI bridge hotplug is disabled
Fixes migration regression from QEMU-1.7 to a newer QEMUs.
SSDT table size in QEMU-1.7 doesn't change regardless of
a number of PCI bridge devices present at startup.
However in QEMU-2.0 since addition of hotplug on PCI bridges,
each PCI bridge adds ~1875 bytes to SSDT table, including
pc-i440fx-1.7 machine type where PCI bridge hotplug disabled
via compat property.
It breaks migration from "QEMU-1.7" to "QEMU-2.[01] -M pc-i440fx-1.7"
since RAMBlock size of ACPI tables on target becomes larger
then on source and migration fails with:
"Length mismatch: /rom@etc/acpi/tables: 2000 in != 3000"
error.
Fix this by generating AML only for PCI0 bus if
hotplug on PCI bridges is disabled and preserves PCI brigde
description in AML as it was done in QEMU-1.7 for pc-i440fx-1.7.
It will help to maintain size of SSDT static regardless of
number of PCI bridges on startup for pc-i440fx-1.7 machine type.

pc: hack for migration compatibility from QEMU 2.0
Changing the ACPI table size causes migration to break, and the memory
hotplug work opened our eyes on how horribly we were breaking things in
2.0 already.
The ACPI table size is rounded to the next 4k, which one would think
gives some headroom. In practice this is not the case, because the user
can control the ACPI table size (each CPU adds 97 bytes to the SSDT and
8 to the MADT) and so some "-smp" values will break the 4k boundary and
fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT.
This patch concerns itself with fixing migration from QEMU 2.0. It
computes the payload size of QEMU 2.0 and always uses that one.
The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size
should always be enough; non-AML tables can change depending on the
configuration (especially MADT, SRAT, HPET) but they remain the same
between QEMU 2.0 and 2.1, so we only compute our padding based on the
sizes of the SSDT and DSDT.
Migration from QEMU 1.7 should work for guests that have a number of CPUs
other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already
broken from QEMU 1.7 to QEMU 2.0 in the same way, though.
Even with this patch, QEMU 1.7 and 2.0 have two different ideas of
"-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to
adopt the QEMU 1.7 definition. I think distributions should apply
it if they move directly from QEMU 1.7 to 2.1+ without ever packaging
version 2.0.

acpi-dsdt: procedurally generate _PRT
This replaces the _PRT constant with a method that computes it.
The problem is that the DSDT+SSDT have grown from 2.0 to 2.1,
enough to cross the 8k barrier (we align the ACPI tables to 4k
before putting them in fw_cfg). This causes problems with
migration and the pc-i440fx-2.0 machine type.
The solution to the problem is to hardcode 64k as the limit,
but this doesn't solve the bug with pc-i440fx-2.0. The fix will be
for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the
ACPI tables. First, however, we must make the actual AML
equal or smaller; to do this, rewrite _PRT in a way that saves
over 1k of bytecode.

vmstate_xhci_event: fix unterminated field list
"vmstate_xhci_event" was introduced in commit
37352df3 ("xhci: add live
migration support"), and first released in v1.6.0. The field list in this
VMSD is not terminated with the VMSTATE_END_OF_LIST() macro.
During normal use (ie. migration), the issue is practically invisible,
because the "vmstate_xhci_event" object (with the unterminated field list)
is only ever referenced -- via "vmstate_xhci_intr" -- if xhci_er_full()
returns true, for the "ev_buffer" test. Since that field_exists() check
(apparently) almost always returns false, we almost never traverse
"vmstate_xhci_event" during migration, which hides the bug.
However, Amit's vmstate checker forces recursion into this VMSD as well,
and the lack of VMSTATE_END_OF_LIST() breaks the field list terminator
check (field->name != NULL) in dump_vmstate_vmsd(). The result is
undefined behavior, which in my case translates to infinite recursion
(because the loop happens to overflow into "vmstate_xhci_intr", which then
links back to "vmstate_xhci_event").
Add the missing terminator.

ppc: fix -mem-path failure
commit
e938ba0c tried to enable -mem-path for ppc but breaked some ppc
boards.
The problems are:
1. it fails when allocating memory for rom, sram whose sizes are less
than huge page size:
./ppc-softmmu/qemu-system-ppc -m 512 -mem-path /hugepages/ \
-kernel /home/hutao/Downloads/vmlinux-ppc -initrd \
/home/hutao/Downloads/initrd-ppc.gz
qemu-system-ppc: /mnt/data/projects/qemu/exec.c:1184: qemu_ram_set_idstr: Assertion `new_block' failed.
2. if there is a numa node backed by memory backend object, qemu fails
with message:
./ppc-softmmu/qemu-system-ppc -m 512 \
-object memory-backend-file,size=512M,mem-path=/hugepages,id=f0 \
-numa node,nodeid=0,memdev=f0 \
-kernel /home/hutao/Downloads/vmlinux-ppc \
-initrd /home/hutao/Downloads/initrd-ppc.gz
qemu-system-ppc: memory backend f0 is used multiple times. Each -numa option must use a different memdev value.
This patch does following:
1. replaces memory_region_allocate_system_memory() with
memory_region_init_ram() for rom, sram. Then only system memory
is backed by hugepages when specifying mem-path.
2. for memory banks, allocates all ram with
one memory_region_allocate_system_memory(), and use
memory_region_init_alias() to initialize memory banks.
Tested machines: default(g3beige), mac99, taihu, bamboo, ref405ep.

virtio-rng: Add human-readable error message for negative max-bytes parameter
If a negative integer is used for the max_bytes parameter, QEMU currently
calls abort() and leaves behind a core dump. This patch replaces the
abort with a simple error message to make the reason for the termination
clearer. This also ensures device-hotplug with invalid input doesn't
cause qemu to quit.
There is an underlying insufficiency in the parameter parsing code of QEMU
that renders it unable to reject negative values for unsigned properties,
thus the error message "a non-negative integer below 2^63" is the most
user-friendly and correct message we can give until the underlying
insufficiency is corrected.

exec: fix migration with devices that use address_space_rw
Devices that use address_space_rw to write large areas to memory
(as opposed to address_space_map/unmap) were broken with respect
to migration since fe680d0 (exec: Limit translation limiting in
address_space_translate to xen, 2014-05-07). Such devices include
IDE CD-ROMs.
The reason is that invalidate_and_set_dirty (called by address_space_rw
but not address_space_map/unmap) was only setting the dirty bit for
the first page in the translation.
To fix this, introduce cpu_physical_memory_set_dirty_range_nocode that
is the same as cpu_physical_memory_set_dirty_range except it does not
muck with the DIRTY_MEMORY_CODE bitmap. This function can be used if
the caller invalidates translations with tb_invalidate_phys_page_range.
There is another difference between cpu_physical_memory_set_dirty_range
and cpu_physical_memory_set_dirty_flag; the former includes a call
to xen_modified_memory. This is handled separately in
invalidate_and_set_dirty, and is not needed in other callers of
cpu_physical_memory_set_dirty_range_nocode, so leave it alone.
Just one nit: now that invalidate_and_set_dirty takes care of handling
multiple pages, there is no need for address_space_unmap to wrap it
in a loop. In fact that loop would now be O(n^2).

The current implementation depends on a configure-time generated list of
block modules. When any of them is absent, module_load() emits a warning.
This is suboptimal because extracting code to modules was mainly done to
allow separate packaging of modules with intrusive dependencies. Absence
of optional packages then leads to absence of modules and an error

virtio-serial-bus: keep port 0 reserved for virtconsole even on unplug
We keep port 0 reserved for compat with older guests, where only
virtio-console was expected. Even if a system is started without a
virtio-console port, port #0 is kept aside. However, after a
virtconsole port is unplugged, port id 0 became available, and the next
hotplug of a virtserialport caused failure due to it not being a console
port.
Steps to reproduce:
$ ./x86_64-softmmu/qemu-system-x86_64 -m 512 -cpu host -enable-kvm -device virtio-serial-pci -monitor stdio -vnc :1
QEMU 2.0.91 monitor - type 'help' for more information

(qemu) device_del p1
(qemu) device_add virtserialport,id=p1
Port number 0 on virtio-serial devices reserved for virtconsole devices for backward compatibility.
Device 'virtserialport' could not be initialized

spapr: Move RMA memory region registration code
PPC970 does not support VRMA (virtual RMA) so real memory required
for SLOF to execute must be allocated by the KVM_ALLOCATE_RMA ioctl.
Later this memory is used as a part of the guest RAM area.
The RMA allocating code also registers a memory region for this piece
of RAM.
We are going to simplify memory regions layout: RMA memory region
will be a subregion in the RAM memory region, both starting from zero.
This way we will not have to take care of start address alignment for
the piece of RAM next to the RMA.
This moves memory region business closer to the RAM memory region
creation/allocation code.
As this is a mechanical patch, no change in behaviour is expected.

target-ppc: Fix number of threads per core limit
The number of threads per core is different for POWER6/7/8 CPUs.
Guest systems do not expect to see more threads per core than
a specific CPU supports so we need to limit this number.
This limit is implemented by ppc_get_compat_smt_threads().
However it has a problem as it checks for PCR (Processor Compatibility
Register) mask, 2.05 means 2 threads per core, 2.06 - 4 threads.
For POWER8 one would expect PCR_COMPAT_2_07 bit set and
ppc_get_compat_smt_threads() checking for it to return 8 threads
per core. But the latest PowerISA spec now is 2.07 and there is
no 2.07 compatibility mode defined, QEMU does not define it either
(will be in PowerISA 2.08).
Instead of relying on a PCR mask, this uses kvmppc_smt_threads()
which returns the maximum supported threads number for KVM or
1 for TCG.
