2f2e911d0c tcg: Remove tcg_check_temp_count, tcg_clear_temp_count
Since all temps allocated by guest front-ends are now TEMP_TB,
and we don't recycle TEMP_TB, there's no point in requiring
that the front-ends free the temps at all.  Begin by dropping
the inner-most checks that all temps have been freed.

5d133dd839 include/qemu/cpuid: Introduce xgetbv_low
Replace the two uses of asm to expand xgetbv with an inline function.
Since one of the two has been using the mnemonic, assume that the
comment about "older versions of the assember" is obsolete, as even
that is 4 years old.

019a98083a softmmu: Check watchpoints for read+write at once
Atomic operations are read-modify-write, and we'd like to
be able to test both read and write with one call.  This is
easy enough, with BP_MEM_READ | BP_MEM_WRITE.

Add BP_HIT_SHIFT to make it easy to set BP_WATCHPOINT_HIT_*.

f85b1fc4a0 tcg: Link branches to the labels
This allows us to easily find all branches that use a label.
Since 'refs' is only tested vs zero, remove it and test for
an empty list instead.  Drop the use of bitfields, which had
been used to pack refs into a single 32-bit word.

ddf0676f1a pnv_phb4_pec: Simplify/align code to parent user-created PHBs
When instantiating a user-created PHB on P9/P10, we don't really have
a reason any more to go through an indirection in pnv_chip_add_phb()
in pnv.c, we can go straight to the right function in
pnv_phb4_pec.c. That way, default PHBs and user-created PHBs are all
handled in the same file.  This patch also renames pnv_phb4_get_pec()
to pnv_pec_add_phb() to better reflect that it "hooks" a PHB to a PEC.

For P8, the PHBs are parented to the chip directly, so it makes sense
to keep calling pnv_chip_add_phb() in pnv.c, to also be consistent
with where default PHBs are handled. The only change here is that,
since that function is now only used for P8, we can refine the return
type.

So overall, the PnvPHB front-end now has a pnv_phb_user_get_parent()
function which handles the parenting of the user-created PHBs by
calling the right function in the right file based on the processor
version. It's also easily extensible if we ever need to support a
different parent object.

fa9dc22aec pnv_phb4_pec: Move pnv_phb4_get_pec() to rightful file
The function pnv_phb4_get_pec() exposes some internals of the PEC and
PHB logic, yet it was in the higher level hw/ppc/pnv.c file for
historical reasons: P8 implements the PHBs from pnv.c directly, but on
P9/P10, it's done through the CEC model, which has its own file. So
move pnv_phb4_get_pec() to hw/pci-host/pnv_phb4_pec.c, where it fits
naturally.

While at it, replace the PnvPHB4 parameter by the PnvPHB front-end,
since it has all the information needed and simplify it a bit.

No functional changes.

1068ebb606 pnv_phb4_pec: Keep track of instantiated PHBs
Add an array on the PEC object to keep track of the PHBs which are
instantiated. The array can be sparsely populated when using
user-created PHBs. It will be useful for the next patch to only export
instantiated PHBs in the device tree.

5aa281d757 aspeed: Introduce a spi_boot region under the SoC
The default boot address of the Aspeed SoCs is 0x0. For this reason,
the FMC flash device contents are remapped by HW on the first 256MB of
the address space. In QEMU, this is currently done in the machine init
with the setup of a region alias.

Move this code to the SoC and introduce an extra container to prepare
ground for the boot ROM region which will overlap the FMC flash
remapping.

6096cf7877 hw/xen: Support MSI mapping to PIRQ
The way that Xen handles MSI PIRQs is kind of awful.

There is a special MSI message which targets a PIRQ. The vector in the
low bits of data must be zero. The low 8 bits of the PIRQ# are in the
destination ID field, the extended destination ID field is unused, and
instead the high bits of the PIRQ# are in the high 32 bits of the address.

Using the high bits of the address means that we can't intercept and
translate these messages in kvm_send_msi(), because they won't be caught
by the APIC — addresses like 0x1000fee46000 aren't in the APIC's range.

So we catch them in pci_msi_trigger() instead, and deliver the event
channel directly.

That isn't even the worst part. The worst part is that Xen snoops on
writes to devices' MSI vectors while they are *masked*. When a MSI
message is written which looks like it targets a PIRQ, it remembers
the device and vector for later.

When the guest makes a hypercall to bind that PIRQ# (snooped from a
marked MSI vector) to an event channel port, Xen *unmasks* that MSI
vector on the device. Xen guests using PIRQ delivery of MSI don't
ever actually unmask the MSI for themselves.

Now that this is working we can finally enable XENFEAT_hvm_pirqs and
let the guest use it all.

Tested with passthrough igb and emulated e1000e + AHCI.

ddf0fd9ae1 hw/xen: Support HVM_PARAM_CALLBACK_TYPE_GSI callback
The GSI callback (and later PCI_INTX) is a level triggered interrupt. It
is asserted when an event channel is delivered to vCPU0, and is supposed
to be cleared when the vcpu_info->evtchn_upcall_pending field for vCPU0
is cleared again.

Thankfully, Xen does *not* assert the GSI if the guest sets its own
evtchn_upcall_pending field; we only need to assert the GSI when we
have delivered an event for ourselves. So that's the easy part, kind of.

There's a slight complexity in that we need to hold the BQL before we
can call qemu_set_irq(), and we definitely can't do that while holding
our own port_lock (because we'll need to take that from the qemu-side
functions that the PV backend drivers will call). So if we end up
wanting to set the IRQ in a context where we *don't* already hold the
BQL, defer to a BH.

However, we *do* need to poll for the evtchn_upcall_pending flag being
cleared. In an ideal world we would poll that when the EOI happens on
the PIC/IOAPIC. That's how it works in the kernel with the VFIO eventfd
pairs — one is used to trigger the interrupt, and the other works in the
other direction to 'resample' on EOI, and trigger the first eventfd
again if the line is still active.

However, QEMU doesn't seem to do that. Even VFIO level interrupts seem
to be supported by temporarily unmapping the device's BARs from the
guest when an interrupt happens, then trapping *all* MMIO to the device
and sending the 'resample' event on *every* MMIO access until the IRQ
is cleared! Maybe in future we'll plumb the 'resample' concept through
QEMU's irq framework but for now we'll do what Xen itself does: just
check the flag on every vmexit if the upcall GSI is known to be
asserted.
