HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort
HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark
HAXM in QEMU as deprecated"), released in v8.0.0.
Per the latest HAXM release (v7.8 [*]), the latest QEMU supported
is v7.2:
Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0.
The next commit (https://github.com/intel/haxm/commit/da1b8ec072)
added:
HAXM v7.8.0 is our last release and we will not accept
pull requests or respond to issues after this.
It became very hard to build and test HAXM. Its previous
maintainers made it clear they won't help. It doesn't seem to be
a very good use of QEMU maintainers to spend their time in a dead
project. Save our time by removing this orphan zombie code.

probe_access_flags() as it is today uses probe_access_full(), which in
turn uses probe_access_internal() with size = 0. probe_access_internal()
then uses the size to call the tlb_fill() callback for the given CPU.
This size param ('fault_size' as probe_access_internal() calls it) is
ignored by most existing .tlb_fill callback implementations, e.g.
arm_cpu_tlb_fill(), ppc_cpu_tlb_fill(), x86_cpu_tlb_fill() and
mips_cpu_tlb_fill() to name a few.
But RISC-V riscv_cpu_tlb_fill() actually uses it. The 'size' parameter
is used to check for PMP (Physical Memory Protection) access. This is
necessary because PMP does not make any guarantees about all the bytes
of the same page having the same permissions, i.e. the same page can
have different PMP properties, so we're forced to make sub-page range
checks. To allow RISC-V emulation to do a probe_acess_flags() that
covers PMP, we need to either add a 'size' param to the existing
probe_acess_flags() or create a new interface (e.g.
probe_access_range_flags).
There are quite a few probe_* APIs already, so let's add a 'size' param
to probe_access_flags() and re-use this API. This is done by open coding
what probe_access_full() does inside probe_acess_flags() and passing the
'size' param to probe_acess_internal(). Existing probe_access_flags()
callers use size = 0 to not change their current API usage. 'size' is
asserted to enforce single page access like probe_access() already does.
No behavioral changes intended.

When AMD's SEV memory encryption is in use, flash memory banks (which are
initialed by pc_system_flash_map()) need to be encrypted with the guest's
key, so that the guest can read them.
That's abstracted via the kvm_memcrypt_encrypt_data() callback in the KVM
state.. except, that it doesn't really abstract much at all.
For starters, the only call site is in code specific to the 'pc'
family of machine types, so it's obviously specific to those and to
x86 to begin with. But it makes a bunch of further assumptions that
need not be true about an arbitrary confidential guest system based on
memory encryption, let alone one based on other mechanisms:
* it assumes that the flash memory is defined to be encrypted with the
guest key, rather than being shared with hypervisor
* it assumes that that hypervisor has some mechanism to encrypt data into
the guest, even though it can't decrypt it out, since that's the whole
point
* the interface assumes that this encrypt can be done in place, which
implies that the hypervisor can write into a confidential guests's
memory, even if what it writes isn't meaningful
So really, this "abstraction" is actually pretty specific to the way SEV
works. So, this patch removes it and instead has the PC flash
initialization code call into a SEV specific callback.

Awareness of an in kernel irqchip is usually local to the machine and its
top-level interrupt controller. However, in a few cases other things need
to know about it. In particular vfio devices need this in order to
accelerate interrupt delivery.
If interrupt routing is changed, such devices may need to readjust their
connection to the KVM irqchip. pci_bus_fire_intx_routing_notifier() exists
to do just this.
However, for the pseries machine type we have a situation where the routing
remains constant but the top-level irq chip itself is changed. This occurs
because of PAPR feature negotiation which allows the guest to decide
between the older XICS and newer XIVE irq chip models (both of which are
paravirtualized).
To allow devices like vfio to adjust to this change, introduce a new
notifier for the purpose kvm_irqchip_change_notify().

This file begins tracking the files that will be the code base for HVF
support in QEMU. This code base is part of Google's QEMU version of
their Android emulator, and can be found at
https://android.googlesource.com/platform/external/qemu/+/emu-master-dev
This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted
Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is
appropriately licensed under GPL v2-or-later, except for the code inside
x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel),
is licensed GPL v2-only.
This code base already implements a very great deal of functionality,
although Google's version removed from Vertuu's the support for APIC
page and hyperv-related stuff. According to the Android Emulator Release
Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now
enabled by default on macOS for 32-bit x86 images to improve performance
and macOS compatibility", although we better use with caution for, as the
same Revision warns us, "If you experience issues with it specifically,
please file a bug report...". The code hasn't seen much update in the
last 5 months, so I think that we can further develop the code with
occasional visiting Google's repository to see if there has been any
update.
On top of Google's code, the following changes were made:
- add code to the configure script to support the --enable-hvf argument.
If the OS is Darwin, it checks for presence of HVF in the system. The
patch also adds strings related to HVF in the file qemu-options.hx.
QEMU will only support the modern syntax style '-M accel=hvf' no enable
hvf; the legacy '-enable-hvf' will not be supported.
- fix styling issues
- add glue code to cpus.c
- move HVFX86EmulatorState field to CPUX86State, changing the
the emulation functions to have a parameter with signature 'CPUX86State *'
instead of 'CPUState *' so we don't have to get the 'env'.
