semihosting/arm-compat-semi: don't use SET_ARG to report SYS_HEAPINFO
As per the spec:
the PARAMETER REGISTER contains the address of a pointer to a
four-field data block.
So we need to follow arg0 and place the results of SYS_HEAPINFO there.

scripts/kernel-doc: strip QEMU_ from function definitions
Some packaged versions of Sphinx (fedora33/alpine so far) have issues
with the annotated C code that kernel-doc spits out. Without knowing
about things like QEMU_PLUGIN_EXPORT it chokes trying to understand
the code. Evidently this is a problem for the kernel as well as the
long stream of regex substitutions we add to in this patch can attest.

exec: Build page-vary-common.c with -fno-lto
In
bbc17caf81f, we used an alias attribute to allow target_page
to be declared const, and yet be initialized late.
This fails when using LTO with several versions of gcc.
The compiler looks through the alias and decides that the const
variable is statically initialized to zero, then propagates that
zero to many uses of the variable.
This can be avoided by compiling one object file with -fno-lto.
In this way, any initializer cannot be seen, and the constant
propagation does not occur.
Since we are certain to have this separate compilation unit, we
can drop the alias attribute as well. We simply have differing
declarations for target_page in different compilation units.
Drop the use of init_target_page, and drop the configure detection
for CONFIG_ATTRIBUTE_ALIAS.
In order to change the compilation flags for a file with meson,
we must use a static_library. This runs into specific_ss, where
we would need to create many static_library instances.
Fix this by splitting page-vary.c: the page-vary-common.c part is
compiled once as a static_library, while the page-vary.c part is
left in specific_ss in order to handle the target-specific value
of TARGET_PAGE_BITS_MIN.

qapi: Rework name checking in preparation of stricter checking
Naming rules differ for the various kinds of names. To prepare
enforcing them, define functions to check them: check_name_upper(),
check_name_lower(), and check_name_camel(). For now, these merely
wrap around check_name_str(), but that will change shortly. Replace
the other uses of check_name_str() by appropriate uses of the
wrappers. No change in behavior just yet.
check_name_str() now returns the name without downstream and x-
prefix, for use by the wrappers in later patches. Requires tweaking
regexp @valid_name. It accepts the same strings as before.

qapi: Permit flat union members for any tag value
Flat union branch names match the tag enum's member names. Omitted
branches default to "no members for this tag value".
Branch names starting with a digit get rejected like "'data' member
'0' has an invalid name". However, omitting the branch works.
This is because flat union tag values get checked twice: as enum
member name, and as union branch name. The former accepts leading
digits, the latter doesn't.
Branches whose names start with a digit therefore cannot have members.
Feels wrong. Get rid of the restriction by skipping the latter check.
This can expose c_name() to input it can't handle: a name starting
with a digit. Improve it to return a valid C identifier for any
input.

target/arm: Make M-profile VTOR loads on reset handle memory aliasing
For Arm M-profile CPUs, on reset the CPU must load its initial PC and
SP from a vector table in guest memory. Because we can't guarantee
reset ordering, we have to handle the possibility that the ROM blob
loader's reset function has not yet run when the CPU resets, in which
case the data in an ELF file specified by the user won't be in guest
memory to be read yet.
We work around the reset ordering problem by checking whether the ROM
blob loader has any data for the address where the vector table is,
using rom_ptr(). Unfortunately this does not handle the possibility
of memory aliasing. For many M-profile boards, memory can be
accessed via multiple possible physical addresses; if the board has
the vector table at address X but the user's ELF file loads data via
a different address Y which is an alias to the same underlying guest
RAM then rom_ptr() will not find it.
Use the new rom_ptr_for_as() function, which deals with memory
aliasing when locating a relevant ROM blob.

hw/core/loader: Add new function rom_ptr_for_as()
For accesses to rom blob data before or during reset, we have a
function rom_ptr() which looks for a rom blob that would be loaded to
the specified address, and returns a pointer into the rom blob data
corresponding to that address. This allows board or CPU code to say
"what is the data that is going to be loaded to this address?".
However, this function does not take account of memory region
aliases. If for instance a machine model has RAM at address
0x0000_0000 which is aliased to also appear at 0x1000_0000, a
rom_ptr() query for address 0x0000_0000 will only return a match if
the guest image provided by the user was loaded at 0x0000_0000 and
not if it was loaded at 0x1000_0000, even though they are the same
RAM and a run-time guest CPU read of 0x0000_0000 will read the data
loaded to 0x1000_0000.
Provide a new function rom_ptr_for_as() which takes an AddressSpace
argument, so that it can check whether the MemoryRegion corresponding
to the address is also mapped anywhere else in the AddressSpace and
look for rom blobs that loaded to that alias.

target/riscv: Prevent lost illegal instruction exceptions
When decode_insn16() fails, we fall back to decode_RV32_64C() for
further compressed instruction decoding. However, prior to this change,
we did not raise an illegal instruction exception, if decode_RV32_64C()
fails to decode the instruction. This means that we skipped illegal
compressed instructions instead of raising an illegal instruction
exception.
Instead of patching decode_RV32_64C(), we can just remove it,
as it is dead code since
f330433b363 anyway.

target/riscv: Add proper two-stage lookup exception detection
The current two-stage lookup detection in riscv_cpu_do_interrupt falls
short of its purpose, as all it checks is whether two-stage address
translation either via the hypervisor-load store instructions or the
MPRV feature would be allowed.
What we really need instead is whether two-stage address translation was
active when the exception was raised. However, in riscv_cpu_do_interrupt
we do not have the information to reliably detect this. Therefore, when
we raise a memory fault exception we have to record whether two-stage
address translation is active.

acpi: Set proper maximum size for "etc/acpi/rsdp" blob
Let's also set a maximum size for "etc/acpi/rsdp", so the maximum
size doesn't get implicitly set based on the initial table size. In my
experiments, the table size was in the range of 22 bytes, so a single
page (== what we used until now) seems to be good enough.
Now that we have defined maximum sizes for all currently used table types,
let's assert that we catch usage with new tables that need a proper maximum
size definition.
Also assert that our initial size does not exceed the maximum size; while
qemu_ram_alloc_internal() properly asserts that the initial RAMBlock size
is <= its maximum size, the result might differ when the host page size
is bigger than 4k.

acpi: Set proper maximum size for "etc/table-loader" blob
The resizeable memory region / RAMBlock that is created for the cmd blob
has a maximum size of whole host pages (e.g., 4k), because RAMBlocks
work on full host pages. In addition, in i386 ACPI code:
acpi_align_size(tables->linker->cmd_blob, ACPI_BUILD_ALIGN_SIZE);
makes sure to align to multiples of 4k, padding with 0.
For example, if our cmd_blob is created with a size of 2k, the maximum
size is 4k - we cannot grow beyond that. Growing might be required
due to guest action when rebuilding the tables, but also on incoming
migration.
This automatic generation of the maximum size used to be sufficient,
however, there are cases where we cross host pages now when growing at
runtime: we exceed the maximum size of the RAMBlock and can crash QEMU when
trying to resize the resizeable memory region / RAMBlock:
$ build/qemu-system-x86_64 --enable-kvm \
-machine q35,nvdimm=on \
-smp 1 \
-cpu host \
-m size=2G,slots=8,maxmem=4G \
-object memory-backend-file,id=mem0,mem-path=/tmp/nvdimm,size=256M \
-device nvdimm,label-size=131072,memdev=mem0,id=nvdimm0,slot=1 \
-nodefaults \
-device vmgenid \
-device intel-iommu
Results in:
Unexpected error in qemu_ram_resize() at ../softmmu/physmem.c:1850:
qemu-system-x86_64: Size too large: /rom@etc/table-loader:
0x2000 > 0x1000: Invalid argument
In this configuration, we consume exactly 4k (32 entries, 128 bytes each)
when creating the VM. However, once the guest boots up and maps the MCFG,
we also create the MCFG table and end up consuming 2 additional entries
(pointer + checksum) -- which is where we try resizing the memory region
/ RAMBlock, however, the maximum size does not allow for it.
Currently, we get the following maximum sizes for our different
mutable tables based on behavior of resizeable RAMBlock:
hw table max_size
------- ---------------------------------------------------------
virt "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
virt "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
virt "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
i386 "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
i386 "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
i386 "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
microvm "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
microvm "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
microvm "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
Let's set the maximum table size for "etc/table-loader" to 64k, so we
can properly grow at runtime, which should be good enough for the future.
Migration is not concerned with the maximum size of a RAMBlock, only
with the used size - so existing setups are not affected. Of course, we
cannot migrate a VM that would have crash when started on older QEMU from
new QEMU to older QEMU without failing early on the destination when
synchronizing the RAM state:
qemu-system-x86_64: Size too large: /rom@etc/table-loader: 0x2000 > 0x1000: Invalid argument
qemu-system-x86_64: error while loading state for instance 0x0 of device 'ram'
qemu-system-x86_64: load of migration failed: Invalid argument
We'll refactor the code next, to make sure we get rid of this implicit
behavior for "etc/acpi/rsdp" as well and to make the code easier to
grasp.

pci: acpi: add _DSM method to PCI devices
Implement _DSM according to:
PCI Firmware Specification 3.1
4.6.7. DSM for Naming a PCI or PCI Express Device Under
Operating Systems
and wire it up to cold and hot-plugged PCI devices.
Feature depends on ACPI hotplug being enabled (as that provides
PCI devices descriptions in ACPI and MMIO registers that are
reused to fetch acpi-index).
acpi-index should work for
- cold plugged NICs:
$QEMU -device e1000,acpi-index=100
=> 'eno100'
- hot-plugged
(monitor) device_add e1000,acpi-index=200,id=remove_me
=> 'eno200'
- re-plugged
(monitor) device_del remove_me
(monitor) device_add e1000,acpi-index=1
=> 'eno1'
Windows also sees index under "PCI Label Id" field in properties
dialog but otherwise it doesn't seem to have any effect.

pci: introduce acpi-index property for PCI device
In x86/ACPI world, linux distros are using predictable
network interface naming since systemd v197. Which on
QEMU based VMs results into path based naming scheme,
that names network interfaces based on PCI topology.
With itm on has to plug NIC in exactly the same bus/slot,
which was used when disk image was first provisioned/configured
or one risks to loose network configuration due to NIC being
renamed to actually used topology.
That also restricts freedom to reshape PCI configuration of
VM without need to reconfigure used guest image.
systemd also offers "onboard" naming scheme which is
preferred over PCI slot/topology one, provided that
firmware implements:
"
PCI Firmware Specification 3.1
4.6.7. DSM for Naming a PCI or PCI Express Device Under
Operating Systems
"
that allows to assign user defined index to PCI device,
which systemd will use to name NIC. For example, using
-device e1000,acpi-index=100
guest will rename NIC to 'eno100', where 'eno' is default
prefix for "onboard" naming scheme. This doesn't require
any advance configuration on guest side to com in effect
at 'onboard' scheme takes priority over path based naming.
Hope is that 'acpi-index' it will be easier to consume by
management layer, compared to forcing specific PCI topology
and/or having several disk image templates for different
topologies and will help to simplify process of spawning
VM from the same template without need to reconfigure
guest NIC.
This patch adds, 'acpi-index'* property and wires up
a 32bit register on top of pci hotplug register block
to pass index value to AML code at runtime.
Following patch will add corresponding _DSM code and
wire it up to PCI devices described in ACPI.

vhost-user: Introduce nested event loop in vhost_user_read()
A deadlock condition potentially exists if a vhost-user process needs
to request something to QEMU on the slave channel while processing a
vhost-user message.
This doesn't seem to affect any vhost-user implementation so far, but
this is currently biting the upcoming enablement of DAX with virtio-fs.
The issue is being observed when the guest does an emergency reboot while
a mapping still exits in the DAX window, which is very easy to get with
a busy enough workload (e.g. as simulated by blogbench [1]) :
- QEMU sends VHOST_USER_GET_VRING_BASE to virtiofsd.
- In order to complete the request, virtiofsd then asks QEMU to remove
the mapping on the slave channel.
All these dialogs are synchronous, hence the deadlock.
As pointed out by Stefan Hajnoczi:
When QEMU's vhost-user master implementation sends a vhost-user protocol
message, vhost_user_read() does a "blocking" read during which slave_fd
is not monitored by QEMU.
The natural solution for this issue is an event loop. The main event
loop cannot be nested though since we have no guarantees that its
fd handlers are prepared for re-entrancy.
Introduce a new event loop that only monitors the chardev I/O for now
in vhost_user_read() and push the actual reading to a one-shot handler.
A subsequent patch will teach the loop to monitor and process messages
from the slave channel as well.
