Igor Mammedov 268430be5e vl:c: make sure that sockets are calculated correctly in '-smp X' case
commit
  (5cdc9b76e3 vl.c: Remove dead assignment)
removed sockets calculation when 'sockets' weren't provided on CLI
since there wasn't any users for it back then. Exiting checks
are neither reachable
   } else if (sockets * cores * threads < cpus) {
or nor triggerable
   if (sockets * cores * threads > max_cpus)
so we weren't noticing wrong topology since then, since users
recalculate sockets adhoc on their own.

However with deprecation check it becomes noticable, for example
  -smp 2
will start printing warning:
  "warning: Invalid CPU topology deprecated: sockets (1) * cores (1) * threads (1) != maxcpus (2)"
calculating sockets if they weren't specified.

Fix it by returning back sockets calculation if it's omitted on CLI.

Igor Mammedov bc1fb850a3 vl.c deprecate incorrect CPUs topology
-smp [cpus],sockets/cores/threads[,maxcpus] should describe topology
so that total number of logical CPUs [sockets * cores * threads]
would be equal to [maxcpus], however historically we didn't have
such check in QEMU and it is possible to start VM with an invalid
topology.
Deprecate invalid options combination so we can make sure that
the topology VM started with is always correct in the future.
Users with an invalid sockets/cores/threads/maxcpus values should
fix their CLI to make sure that
   [sockets * cores * threads] == [maxcpus]

Richard Henderson 93f379b0c4 target/arm: Only flush tlb if ASID changes
Since QEMU does not implement ASIDs, changes to the ASID must flush the
tlb.  However, if the ASID does not change there is no reason to flush.

In testing a boot of the Ubuntu installer to the first menu, this reduces
the number of flushes by 30%, or nearly 600k instances.

Stewart Hildebrand ea358872a6 hw/arm/boot: Increase compliance with kernel arm64 boot protocol
"The Image must be placed text_offset bytes from a 2MB aligned base
address anywhere in usable system RAM and called there."

For the virt board, we write our startup bootloader at the very
bottom of RAM, so that bit can't be used for the image. To avoid
overlap in case the image requests to be loaded at an offset
smaller than our bootloader, we increment the load offset to the
next 2MB.

This fixes a boot failure for Xen AArch64.

For the v7 version of the Arm architecture, the IL bit in
syndrome register values where the field is not valid was

QEMU currently implements. Handle the desired v7 behaviour
by squashing the IL bit for the affected cases:
 * EC == EC_UNCATEGORIZED
 * prefetch aborts
 * data aborts where ISV is 0

(The fourth case listed in the v8 Arm ARM DDI 0487C.a in
section G7.2.70, "illegal state exception", can't happen
on a v7 CPU.)

This deals with a corner case noted in a comment.

always showing the physical interrupt status.

We don't currently implement anything to do with external

ought to be possible for the outer guest to present a virtual
external abort to the inner guest, even if QEMU doesn't
emulate physical external aborts, so there is missing

Peter Maydell 81e3728407 target/arm: Improve debug logging of AArch32 exception return
For AArch32, exception return happens through certain kinds
of CPSR write. We don't currently have any CPU_LOG_INT logging
of these events (unlike AArch64, where we log in the ERET
instruction). Add some suitable logging.

This will log exception returns like this:
Exception return from AArch32 hyp to usr PC 0x80100374

paralleling the existing logging in the exception_return
helper for AArch64 exception returns:
Exception return from AArch64 EL2 to AArch64 EL0 PC 0x8003045c
Exception return from AArch64 EL2 to AArch32 EL0 PC 0x8003045c

(Note that an AArch32 exception return can only be
AArch32->AArch32, never to AArch64.)

Richard Henderson 09cbd50198 target/arm: Convert jazelle from feature bit to isar1 test
Having V6 alone imply jazelle was wrong for cortex-m0.
Change to an assertion for V6 & !M.

This was harmless, because the only place we tested ARM_FEATURE_JAZELLE
was for 'bxj' in disas_arm(), which is unreachable for M-profile cores.

Richard Henderson 7e0cf8b47f target/arm: Convert division from feature bits to isar0 tests
Both arm and thumb2 division are controlled by the same ISAR field,
which takes care of the arm implies thumb case.  Having M imply
thumb2 division was wrong for cortex-m0, which is v6m and does not
have thumb2 at all, much less thumb2 division.

Richard Henderson 962fcbf2ef target/arm: Convert v8 extensions from feature bits to isar tests
Most of the v8 extensions are self-contained within the ISAR

makes them the easiest to convert.

Dongjiu Geng 202ccb6bab target/arm: Add support for VCPU event states
This patch extends the qemu-kvm state sync logic with support for
KVM_GET/SET_VCPU_EVENTS, giving access to yet missing SError exception.
And also it can support the exception state migration.

The SError exception states include SError pending state and ESR value,
the kvm_put/get_vcpu_events() will be called when set or get system
registers. When do migration, if source machine has SError pending,
QEMU will do this migration regardless whether the target machine supports
to specify guest ESR value, because if target machine does not support that,
it can also inject the SError with zero ESR value.

Markus Armbruster 61e9e3cb45 ssi-sd: Make devices picking up backends unavailable with -device
Device models aren't supposed to go on fishing expeditions for
backends.  They should expose suitable properties for the user to set.
For onboard devices, board code sets them.

Device ssi-sd picks up its block backend in its init() method with
drive_get_next() instead.  This mistake is already marked FIXME since
commit af9e40a.

Unset user_creatable to remove the mistake from our external
interface.  Since the SSI bus doesn't support hotplug, only -device
can be affected.  Only certain ARM machines have ssi-sd and provide an
SSI bus for it; this patch breaks -device ssi-sd for these machines.
No actual use of -device ssi-sd is known.

Liam Merwick 86583a07c4 configure: Provide option to explicitly disable AVX2
The configure script detects if the compiler has AVX2 support and
automatically sets avx2_opt="yes" which in turn defines CONFIG_AVX2_OPT.
There is no way of explicitly overriding this setting so this commit adds
two command-line options: --enable-avx2 and --disable-avx2.

The default behaviour, when no option is specified, is to maintain the
current behaviour and enable AVX2 if the compiler supports it.
