379ae096f7 spapr_drc: add unrealize method to physical DRC class
When hot-unplugging a PHB, all its PCI DRC connectors get unrealized. This
patch adds an unrealize method to the physical DRC class, in order to undo
registrations performed in realize_physical().

10f12e6450 hw/ppc: CAS reset on early device hotplug
This patch is a follow up on the discussions made in patch
"hw/ppc: disable hotplug before CAS is completed" that can be
found at [1].

At this moment, we do not support CPU/memory hotplug in early
boot stages, before CAS. When a hotplug occurs, the event is logged
in an internal RTAS event log queue and an IRQ pulse is fired. In
regular conditions, the guest handles the interrupt by executing
check_exception, fetching the generated hotplug event and enabling
the device for use.

In early boot, this IRQ isn't caught (SLOF does not handle hotplug
events), leaving the event in the rtas event log queue. If the guest
executes check_exception due to another hotplug event, the re-assertion
of the IRQ ends up de-queuing the first hotplug event as well. In short,
a device hotplugged before CAS is considered coldplugged by SLOF.
This leads to device misbehavior and, in some cases, guest kernel
Ooops when trying to unplug the device.

A proper fix would be to turn every device hotplugged before CAS
as a colplugged device. This is not trivial to do with the current
code base though - the FDT is written in the guest memory at
ppc_spapr_reset and can't be retrieved without adding extra state
(fdt_size for example) that will need to managed and migrated. Adding
the hotplugged DT in the middle of CAS negotiation via the updated DT
tree works with CPU devs, but panics the guest kernel at boot. Additional
analysis would be necessary for LMBs and PCI devices. There are
questions to be made in QEMU/SLOF/kernel level about how we can make
this change in a sustainable way.

With Linux guests, a fix would be the kernel executing check_exception
at boot time, de-queueing the events that happened in early boot and
processing them. However, even if/when the newer kernels start
fetching these events at boot time, we need to take care of older
kernels that won't be doing that.

This patch works around the situation by issuing a CAS reset if a hotplugged
device is detected during CAS:

- the DRC conditions that warrant a CAS reset is the same as those that
triggers a DRC migration - the DRC must have a device attached and
the DRC state is not equal to its ready_state. With that in mind, this
patch makes use of 'spapr_drc_needed' to determine if a CAS reset
is needed.

- In the middle of CAS negotiations, the function
'spapr_hotplugged_dev_before_cas' goes through all the DRCs to see
if there are any DRC that requires a reset, using spapr_drc_needed. If
that happens, returns '1' in 'spapr_h_cas_compose_response' which will set
spapr->cas_reboot to true, causing the machine to reboot.

No changes are made for coldplug devices.

5625817423 hw/ppc: clear pending_events on machine reset
The sPAPR machine isn't clearing up the pending events QTAILQ on
machine reboot. This allows for unprocessed hotplug/epow events
to persist in the queue after reset and, when reasserting the IRQs in
check_exception later on, these will be being processed by the OS.

This patch implements a new function called 'spapr_clear_pending_events'
that clears up the pending_events QTAILQ. This helper is then called
inside ppc_spapr_reset to clear up the events queue, preventing
old/deprecated events from persisting after a reset.

c618e300eb hw/ppc/spapr_drc.c: change spapr_drc_needed to use drc->dev
This patch makes a small fix in 'spapr_drc_needed' to change how we detect
if a DRC has a device attached. Previously it used dr_entity_sense for this,
which  works for physical DRCs.

However, for logical DRCs, it didn't cover the case where a logical DRC has
a drc->dev but the state is LOGICAL_UNUSABLE (e.g. a hotplugged CPU before
CAS). In this case, the dr_entity_sense of this DRC returns UNUSABLE and the
code was considering that there were no dev attached, making spapr_drc_needed
return 'false' when in fact we would like to migrate the DRC.

Changing it to check for drc->dev instead works for all DRC types.

4672cbd7be hw/arm: Set ignore_memory_transaction_failures for most ARM boards
Set the MachineClass flag ignore_memory_transaction_failures
for almost all ARM boards. This means they retain the legacy
behaviour that accesses to unimplemented addresses will RAZ/WI
rather than aborting, when a subsequent commit adds support
for external aborts.

The exceptions are:
 * virt -- we know that guests won't try to prod devices
   that we don't describe in the device tree or ACPI tables
 * mps2 -- this board was written to use unimplemented-device
   for all the ranges with devices we don't yet handle

New boards should not set the flag, but instead be written
like the mps2.

9d40cd8a68 target/arm: Make CCR register banked for v8M
Make the CCR register banked if v8M security extensions are enabled.

This is slightly more complicated than the other "add banking"
patches because there is one bit in the register which is not
banked. We keep the live data in the NS copy of the register,
and adjust it on register reads and writes. (Since we don't
currently implement the behaviour that the bit controls, there
is nowhere else that needs to care.)

This patch includes the enforcement of the bits which are newly
RES1 in ARMv8M.

The v8M ARM ARM introduces a notation where individual paragraphs
are labelled with R (for rule) or I (for information) followed
by a random group of subscript letters. In comments where we want
to refer to a particular part of the manual we use this convention,
which should be more stable across document revisions than using
section or page numbers.

0e1a46bbd2 target/arm: Implement ARMv8M's PMSAv8 registers
As part of ARMv8M, we need to add support for the PMSAv8 MPU
architecture.

PMSAv8 differs from PMSAv7 both in register/data layout (for instance
using base and limit registers rather than base and size) and also in
behaviour (for example it does not have subregions); rather than
trying to wedge it into the existing PMSAv7 code and data structures,
we define separate ones.

This commit adds the data structures which hold the state for a
PMSAv8 MPU and the register interface to it.  The implementation of
the MPU behaviour will be added in a subsequent commit.

Exiting just due to a "device_add" should not happen. Looking closer

reveals that it is using serial_hds and nd_table directly there, so
this device is clearly not creatable by the user and should be marked

In the case O_PATH is supported, we rely on the behavhior of openat(2)
when passing O_NOFOLLOW | O_PATH and the file is a symbolic link. Even
if openat_file() already adds O_NOFOLLOW to the flags, this patch makes
it explicit that we need both creation flags to obtain the expected

This logic error meant we were not setting the PTZ

this wouldn't have had any effects beyond making GIC
initialization take a little longer.

f58f25599b hw/arm/digic: Mark device with user_creatable = false
QEMU currently shows some unexpected behavior when the user trys to
do a "device_add digic" on an unrelated ARM machine like integratorcp
in "-nographic" mode (the device_add command does not immediately
return to the monitor prompt), and trying to "device_del" the device
later results in a "qemu/qdev-monitor.c:872:qdev_unplug: assertion
failed: (hotplug_ctrl)" error condition.
Looking at the realize function of the device, it uses serial_hds
directly and this means that the device can not be added a second
time, so let's simply mark it with "user_creatable = false" now.

469f3da42e hw/arm/aspeed_soc: Mark devices as user_creatable = false
QEMU currently aborts if the user is accidentially trying to

The ast2400 SoC devices are clearly not creatable by the user since
they are using the serial_hds and nd_table arrays directly in their
realize function, so mark them with user_creatable = false.

f55d613bc9 watchdog: wdt_aspeed: Add support for the reset width register
The reset width register controls how the pulse on the SoC's WDTRST{1,2}
pins behaves. A pulse is emitted if the external reset bit is set in
WDT_CTRL. On the AST2500 WDT_RESET_WIDTH can consume magic bit patterns
to configure push-pull/open-drain and active-high/active-low
behaviours and thus needs some special handling in the write path.

As some of the capabilities depend on the SoC version a silicon-rev
property is introduced, which is used to guard version-specific
behaviour.

b2bfe9f7f1 target/arm/kvm: pmu: improve error handling
If a KVM PMU init or set-irq attr call fails we just silently stop
the PMU DT node generation. The only way they could fail, though,
is if the attr's respective KVM has-attr call fails. But that should
never happen if KVM advertises the PMU capability, because both
attrs have been available since the capability was introduced. Let's
just abort if this should-never-happen stuff does happen, because,
if it does, then something is obviously horribly wrong.

eb578a2394 nvic: Implement "user accesses BusFault" SCS region behaviour
The ARMv7M architecture specifies that most of the addresses in the
PPB region (which includes the NVIC, systick and system registers)
are not accessible to unprivileged accesses, which should
BusFault with a few exceptions:
 * the STIR is configurably user-accessible
 * the ITM (which we don't implement at all) is always
   user-accessible

Implement this by switching the register access functions
to the _with_attrs scheme that lets us distinguish user
mode accesses.

This allows us to pull the handling of the CCR.USERSETMPEND
flag up to the level where we can make it generate a BusFault
as it should for non-permitted accesses.

Note that until the core ARM CPU code implements turning
MEMTX_ERROR into a BusFault the registers will continue to
act as RAZ/WI to user accesses.

e6ae5981ea target/arm: Don't store M profile PRIMASK and FAULTMASK in daif
We currently store the M profile CPU register state PRIMASK and
FAULTMASK in the daif field of the CPU state in its I and F
bits. This is a legacy from the original implementation, which
tried to share the cpu_exec_interrupt code between A profile
and M profile. We've since separated out the two cases because
they are significantly different, so now there is no common
code between M and A profile which looks at env->daif: all the
uses are either in A-only or M-only code paths. Sharing the state
fields now is just confusing, and will make things awkward
when we implement v8M, where the PRIMASK and FAULTMASK
registers are banked between security states.

Switch M profile over to using v7m.faultmask and v7m.primask
fields for these registers.

f7abe0ecd4 qapi: Change data type of the FOO_lookup generated for enum FOO
Currently, a FOO_lookup is an array of strings terminated by a NULL
sentinel.

A future patch will generate enums with "holes".  NULL-termination
will cease to work then.

To prepare for that, store the length in the FOO_lookup by wrapping it
in a struct and adding a member for the length.

The sentinel will be dropped next.

79c5a10cdd qxl: drop mono cursor support
The chunk size sanity check in qxl_render_cursor works for
SPICE_CURSOR_TYPE_ALPHA cursors only.  So support for
SPICE_CURSOR_TYPE_MONO cursors must be broken for ages without anyone
noticing.  Most likely it simply isn't used any more by guest drivers.
Drop the dead code.

3d90c62548 vga: stop passing pointers to vga_draw_line* functions
Instead pass around the address (aka offset into vga memory).
Add vga_read_* helper functions which apply vbe_size_mask to
the address, to make sure the address stays within the valid
range, similar to the cirrus blitter fixes (commits ffaf857778
and 026aeffcb4).

Impact:  DoS for privileged guest users.  qemu crashes with
a segfault, when hitting the guard page after vga memory
allocation, while reading vga memory for display updates.

No need for kvm_enabled() as this function is only called from KVM and
there is no reason why it shouldn't be allowed for tcg. It is simply not
available under tcg.

Also, there is no need to check for the machine type anymore. Just like
ri_enabled(), we can directly use the stored flag, which results in
"true" for the "none" machine.
