ppc/xics: remove set_nr_irqs() handler from XICSStateClass
Today, the ICS (Interrupt Controller Source) object is created and
realized by the init and realize routines of the XICS object, but some
of the parameters are only known at the machine level.
These parameters are passed from the sPAPR machine to the ICS object
in a rather convoluted way using property handlers and a class handler
of the XICS object. The number of irqs required to allocate the IRQ
state objects in the ICS realize routine is one of them.
Let's simplify the process by creating the ICS object along with the
XICS object at the machine level and link the ICS into the XICS list
of ICSs at this level also. In the sPAPR machine, there is only a
single ICS but that will change with the PowerNV machine.
Also, QOMify the creation of the objects and get rid of the
superfluous code.

xics: XICS should not be a SysBusDevice
Currently xics - the component of the IBM POWER interrupt controller
representing the overall interrupt fabric / architecture is
represented as a descendent of SysBusDevice. However, this is not
really correct - the xics presents nothing in MMIO space so it should
be an "unattached" device in the current QOM model.
Since this device will always be created by the machine type, not created
specifically from the command line, and because it has no migrated state
it should be safe to move it around the device composition tree.
Therefore this patch changes it to a descendent of TYPE_DEVICE, and
makes it an unattached device. So that its reset handler still gets
called correctly, we add a qdev_set_parent_bus() to attach it to
sysbus. It's not really clear that's correct (instead of using
register_reset()) but it appears to a common technique.

This behaviour change is not actually a bug since no assumptions should be
made on DT ordering. But it has no real justification either, other than
being the consequence of the way fdt_add_subnode() inserts new elements
to the front of the FDT rather than adding them to the tail.
This patch reverts to the historical SLOF ordering by walking PCI devices
in reverse order. This reconciles pseries with x86 machine types behavior.
It is expected to make things easier when porting existing applications to
power.

target/ppc: Manage external HPT via virtual hypervisor
The pseries machine type implements the behaviour of a PAPR compliant
hypervisor, without actually executing such a hypervisor on the virtual
CPU. To do this we need some hooks in the CPU code to make hypervisor
facilities get redirected to the machine instead of emulated internally.
For hypercalls this is managed through the cpu->vhyp field, which points
to a QOM interface with a method implementing the hypercall.
For the hashed page table (HPT) - also a hypervisor resource - we use an
older hack. CPUPPCState has an 'external_htab' field which when non-NULL
indicates that the HPT is stored in qemu memory, rather than within the
guest's address space.
For consistency - and to make some future extensions easier - this merges
the external HPT mechanism into the vhyp mechanism. Methods are added
to vhyp for the basic operations the core hash MMU code needs: map_hptes()
and unmap_hptes() for reading the HPT, store_hpte() for updating it and
hpt_mask() to retrieve its size.
To match this, the pseries machine now sets these vhyp fields in its
existing vhyp class, rather than reaching into the cpu object to set the
external_htab field.

target/ppc: Eliminate htab_base and htab_mask variables
CPUPPCState includes fields htab_base and htab_mask which store the base
address (GPA) and size (as a mask) of the guest's hashed page table (HPT).
These are set when the SDR1 register is updated.
Keeping these in sync with the SDR1 is actually a little bit fiddly, and
probably not useful for performance, since keeping them expands the size of
CPUPPCState. It also makes some upcoming changes harder to implement.
This patch removes these fields, in favour of calculating them directly
from the SDR1 contents when necessary.
This does make a change to the behaviour of attempting to write a bad value
(invalid HPT size) to the SDR1 with an mtspr instruction. Previously, the
bad value would be stored in SDR1 and could be retrieved with a later
mfspr, but the HPT size as used by the softmmu would be, clamped to the
allowed values. Now, writing a bad value is treated as a no-op. An error
message is printed in both new and old versions.
I'm not sure which behaviour, if either, matches real hardware. I don't
think it matters that much, since it's pretty clear that if an OS writes
a bad value to SDR1, it's not going to boot.

target/ppc: Cleanup HPTE accessors for 64-bit hash MMU
Accesses to the hashed page table (HPT) are complicated by the fact that
the HPT could be in one of three places:
1) Within guest memory - when we're emulating a full guest CPU at the
hardware level (e.g. powernv, mac99, g3beige)
2) Within qemu, but outside guest memory - when we're emulating user and
supervisor instructions within TCG, but instead of emulating
the CPU's hypervisor mode, we just emulate a hypervisor's behaviour
(pseries in TCG or KVM-PR)
3) Within the host kernel - a pseries machine using KVM-HV
acceleration. Mostly accesses to the HPT are handled by KVM,
but there are a few cases where qemu needs to access it via a
special fd for the purpose.
In order to batch accesses to the fd in case (3), we use a somewhat awkward
ppc_hash64_start_access() / ppc_hash64_stop_access() pair, which for case
(3) reads / releases several HPTEs from the kernel as a batch (usually a
whole PTEG). For cases (1) & (2) it just returns an address value. The
actual HPTE load helpers then need to interpret the returned token
differently in the 3 cases.
This patch keeps the same basic structure, but simplfiies the details.
First start_access() / stop_access() are renamed to map_hptes() and
unmap_hptes() to make their operation more obvious. Second, map_hptes()
now always returns a qemu pointer, which can always be used in the same way
by the load_hpte() helpers. In case (1) it comes from address_space_map()
in case (2) directly from qemu's HPT buffer and in case (3) from a
temporary buffer read from the KVM fd.
While we're at it, make things a bit more consistent in terms of types and
variable names: avoid variables named 'index' (it shadows index(3) which
can lead to confusing results), use 'hwaddr ptex' for HPTE indices and
uint64_t for each of the HPTE words, use ptex throughout the call stack
instead of pte_offset in some places (we still need that at the bottom
layer, but nowhere else).

Now that this is done, we don't need to check for an external HPT executing
mtsdr1: an external HPT only applies when we're emulating the behaviour of

target/ppc: Fix KVM-HV HPTE accessors
When a 'pseries' guest is running with KVM-HV, the guest's hashed page
table (HPT) is stored within the host kernel, so it is not directly
accessible to qemu. Most of the time, qemu doesn't need to access it:
we're using the hardware MMU, and KVM itself implements the guest
hypercalls for manipulating the HPT.
However, qemu does need access to the in-KVM HPT to implement
get_phys_page_debug() for the benefit of the gdbstub, and maybe for
other debug operations.
To allow this,
7c43bca "target-ppc: Fix page table lookup with kvm
enabled" added kvmppc_hash64_read_pteg() to target/ppc/kvm.c to read
in a batch of HPTEs from the KVM table. Unfortunately, there are a
couple of problems with this:
First, the name of the function implies it always reads a whole PTEG
from the HPT, but in fact in some cases it's used to grab individual
HPTEs (which ends up pulling 8 HPTEs, not aligned to a PTEG from the
kernel).
Second, and more importantly, the code to read the HPTEs from KVM is
simply wrong, in general. The data from the fd that KVM provides is
designed mostly for compact migration rather than this sort of one-off
access, and so needs some decoding for this purpose. The current code
will work in some cases, but if there are invalid HPTEs then it will
not get sane results.
This patch rewrite the HPTE reading function to have a simpler
interface (just read n HPTEs into a caller provided buffer), and to
correctly decode the stream from the kernel.
For consistency we also clean up the similar function for altering
HPTEs within KVM (introduced in
c138593 "target-ppc: Update
ppc_hash64_store_hpte to support updating in-kernel htab").

cputlb: Don't assume do_unassigned_access() never returns
In get_page_addr_code(), if the guest PC doesn't correspond to RAM
then we currently run the CPU's do_unassigned_access() hook if it has
one, and otherwise we give up and exit QEMU with a more-or-less
useful message. This code assumes that the do_unassigned_access hook
will never return, because if it does then we'll plough on attempting
to use a non-RAM TLB entry to get a RAM address and will abort() in
qemu_ram_addr_from_host_nofail(). Unfortunately some CPU
implementations of this hook do return: Microblaze, SPARC and the ARM
v7M.
Change the code to call report_bad_exec() if the hook returns, as
well as if it didn't have one. This means we can tidy it up to use
the cpu_unassigned_access() function which wraps the "get the CPU
class and call the hook if it has one" work, since we aren't trying
to distinguish "no hook" from "hook existed and returned" any more.
This brings the handling of this hook into line with the handling
used for data accesses, where "hook returned" is treated the
same as "no hook existed" and gets you the default behaviour.

bcm2835_rng: Use qcrypto_random_bytes() rather than rand()
Switch to using qcrypto_random_bytes() rather than rand() as
our source of randomness for the BCM2835 RNG.
If qcrypto_random_bytes() fails, we don't want to return the guest a
non-random value in case they're really using it for cryptographic
purposes, so the best we can do is a fatal error. This shouldn't
happen unless something's broken, though.
In theory we could implement this device's full FIFO and interrupt
semantics and then just stop filling the FIFO. That's a lot of work,
though, and doesn't really give a very nice diagnostic to the user
since the guest will just seem to hang.

target-arm: Implement BCM2835 hardware RNG
Recent vanilla Raspberry Pi kernels started to make use of
the hardware random number generator in BCM2835 SoC. As a
result, those kernels wouldn't work anymore under QEMU
but rather just freeze during the boot process.
This patch implements a trivial BCM2835 compatible RNG,
and adds it as a peripheral to BCM2835 platform, which
allows to boot a vanilla Raspberry Pi kernel under Qemu.
Changes since v1:
* Prevented guest from writing [31..20] bits in rng_status
* Removed redundant minimum_version_id_old
* Added field entries for the state
* Changed realize function to reset

ui: Use XkbGetMap and XkbGetNames instead of XkbGetKeyboard
XkbGetKeyboard does not work in XWayland and even on non-Wayland
X11 servers its use is discouraged:
https://bugs.freedesktop.org/show_bug.cgi?id=89240
This resolves a problem whereby QEMU prints
"could not lookup keycode name"
on startup when running under XWayland. Keymap handling is
however still broken after this commit, since Xwayland is
reporting a keymap we can't handle
"unknown keycodes `(unnamed)', please report to qemu-devel@nongnu.org"
NB, native Wayland support (which is the default under GTK3) is
not affected - only XWayland (which can be requested with GDK_BACKEND
on GTK3, and is the only option for GTK2).

iscsi: do not use aio_context_acquire/release
Now that all bottom halves and callbacks take care of taking the
AioContext lock, we can migrate some users away from it and to a
specific QemuMutex or CoMutex.
Protect libiscsi calls with a QemuMutex. Callbacks are invoked
using bottom halves, so we don't even have to drop it around
callback invocations.
