32-bit x86 systems do not have a reserved memory for hole64. On those 32-bit
systems without PSE36 or PAE CPU features, hotplugging memory devices are not
supported by QEMU as QEMU always places hotplugged memory above 4 GiB boundary
which is beyond the physical address space of the processor. Linux guests also
does not support memory hotplug on those systems. Please see Linux
kernel commit b59d02ed08690 ("mm/memory_hotplug: disable the functionality
for 32b") for more details.
Therefore, the maximum limit of the guest physical address in the absence of
additional memory devices effectively coincides with the end of
"above 4G memory space" region for 32-bit x86 without PAE/PSE36. When users
configure additional memory devices, after properly accounting for the
additional device memory region to find the maximum value of the guest
physical address, the address will be outside the range of the processor's
physical address space.
This change adds improvements to take above into consideration.
For example, previously this was allowed:
$ ./qemu-system-x86_64 -cpu pentium -m size=10G
With this change now it is no longer allowed:
$ ./qemu-system-x86_64 -cpu pentium -m size=10G
qemu-system-x86_64: Address space limit 0xffffffff < 0x2bfffffff phys-bits too low (32)
However, the following are allowed since on both cases physical address
space of the processor is 36 bits:
$ ./qemu-system-x86_64 -cpu pentium2 -m size=10G
$ ./qemu-system-x86_64 -cpu pentium,pse36=on -m size=10G
For 32-bit, without PAE/PSE36, hotplugging additional memory is no longer allowed.
$ ./qemu-system-i386 -m size=1G,maxmem=3G,slots=2
qemu-system-i386: Address space limit 0xffffffff < 0x1ffffffff phys-bits too low (32)
$ ./qemu-system-i386 -machine q35 -m size=1G,maxmem=3G,slots=2
qemu-system-i386: Address space limit 0xffffffff < 0x1ffffffff phys-bits too low (32)
A new compatibility flag is introduced to make sure pc_max_used_gpa() keeps
returning the old value for machines 8.1 and older.
Therefore, the above is still allowed for older machine types in order to support
compatibility. Hence, the following still works:
$ ./qemu-system-i386 -machine pc-i440fx-8.1 -m size=1G,maxmem=3G,slots=2
$ ./qemu-system-i386 -machine pc-q35-8.1 -m size=1G,maxmem=3G,slots=2
Further, following is also allowed as with PSE36, the processor has 36-bit
address space:
$ ./qemu-system-i386 -cpu 486,pse36=on -m size=1G,maxmem=3G,slots=2
After calling CPUID with EAX=0x80000001, all AMD64 compliant processors
have the longmode-capable-bit turned on in the extended feature flags (bit 29)
in EDX. The absence of CPUID longmode can be used to differentiate between
32-bit and 64-bit processors and is the recommended approach. QEMU takes this
approach elsewhere (for example, please see x86_cpu_realizefn()), With
this change, pc_max_used_gpa() also uses the same method to detect 32-bit
processors.
Unit tests are modified to not run 32-bit x86 tests that use memory hotplug.

The migration qtest all the way up to this point used to work by sheer
luck relying on the contents of all pages from 1MiB to 100MiB to contain
the same one value in the first byte initially.
This easily breaks if we reduce the amount of RAM for the test instances
from 150MiB to e.g 110MiB since that makes SeaBIOS dirty some of the
pages starting at about 0x5dd2000 (~93 MiB) as it reuses those for the
HighMemory allocator since commit dc88f9b72df ("malloc: use large
ZoneHigh when there is enough memory").
This would result in the following errors:

When compiling this file with -Wshadow=local , we get:

Rename the QTestState variable to "qts" which is the common
naming for such a variable in other tests.

The test actually requires Python bindings to libnbd rather than libnbd
itself. Clarify that inside the message.

We need to check that we are able to create large enough file which is
used as an export base rather than connection URL. Unfortunately, there
are cases when the TEST_IMG_FILE is not defined. We should fallback to
TEST_IMG in that case.
This problem has been detected when running
./check -nbd 5
The test should be able to run while it does not.

This will enable removing deprecated default audiodev support.
I did not figure out how to make the audiodev represented as an
interface node, so this is a workaround. I am not sure what would be
the proper way.

For user-only mode we reveal a subset of the AArch64 ID registers
to the guest, to emulate the kernel's trap-and-emulate-ID-regs
handling. Update the feature bit masks to match upstream kernel
commit a48fa7efaf1161c1c.
None of these features are yet implemented by QEMU, so this
doesn't yet have a behavioural change, but implementation of
FEAT_MOPS and FEAT_HBC is imminent.
