We were passing a NULL error pointer to the object_property_set_bool()
call that realizes the CPU object. This meant that we wouldn't detect
failure, and would plough blindly on to crash later trying to use a
NULL CPU object pointer. Detect errors and fail instead.
In particular, this will be necessary to detect the user error
of using "-cpu host" without "-enable-kvm" once we make the host
CPU type be registered unconditionally rather than only in
kvm_arch_init().

When determining the group priority of a group 1 IRQ, if C_CTRL.CBPR is
0, the non-secure BPR value is used. However, this value must be
incremented by one so that it matches the secure world number of
implemented priority bits (NS world has one less priority bit compared
to the Secure world).

[PMM: add assert, as the gicv3 code has]
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
When there is no active interrupts in the GIC, a read to the C_RPR
register should return the value of the "Idle priority", which is either
the maximum value an IRQ priority field can be set to, or 0xff.
Since the QEMU GIC model implements all the 8 priority bits, the Idle
priority is 0xff.
Internally, when there is no active interrupt, the running priority
value is 0x100. The gic_get_running_priority function returns an uint8_t
and thus, truncate this value to 0x00 when returning it. This is wrong since
a value of 0x00 correspond to the maximum possible priority.
This commit fixes the returned value when the internal value is 0x100.
Note that it is correct for the Non-Secure view to return 0xff even
though from the NS world point of view, only 7 priority bits are
implemented. The specification states that the Idle priority can be 0xff
even when not all the 8 priority bits are implemented. This has been
verified against a real GICv2 hardware on a Xilinx ZynqMP based board.
Regarding the ARM11MPCore version of the GIC, the specification is not
clear on that point, so this commit does not alter its behavior.

In the GIC, when an IRQ is acknowledged, its state goes from "pending"
to:
- "active" if the corresponding IRQ pin has been de-asserted
- "active and pending" otherwise.
The GICv2 manual states that when a IRQ becomes active (or active and
pending), the GIC should either signal another (higher priority) IRQ to
the CPU if there is one, or de-assert the CPU IRQ pin.
The current implementation of the GIC in QEMU does not check if the
IRQ is already active when looking for pending interrupts with
sufficient priority in gic_update(). This can lead to signaling an
interrupt that is already active.
This usually happens when splitting priority drop and interrupt
deactivation. On priority drop, the IRQ stays active until deactivation.
If it becomes pending again, chances are that it will be incorrectly
selected as best_irq in gic_update().
This commit fixes this by checking if the IRQ is not already active when
looking for best_irq in gic_update().
Note that regarding the ARM11MPCore GIC version, the corresponding
manual is not clear on that point, but it has has no priority
drop/interrupt deactivation separation, so this case should not happen.

The actual imx_eth_enable_rx() function is buggy.
It updates s->regs[ENET_RDAR] after calling qemu_flush_queued_packets().
qemu_flush_queued_packets() is going to call imx_XXX_receive() which itself
is going to call imx_eth_enable_rx().
By updating s->regs[ENET_RDAR] after calling qemu_flush_queued_packets()
we end up updating the register with an outdated value which might
lead to disabling the receive function in the i.MX FEC/ENET device.
This patch change the place where the register update is done so that the
register value stays up to date and the receive function can keep
running.

With the LEON3 IRQ controller IRQs can be acknowledged 2 ways:
* Explicitly by software writing to the CLEAR_OFFSET register
* Implicitly when the procesor is done running the trap handler attached
to the IRQ.
The actual IRQMP code only allows the implicit processor triggered IRQ ack.
If software write explicitly to the CLEAR_OFFSET register, this will clear
the pending bit in the register value but this will not lower the ongoing
raised IRQ with the processor. The IRQ will be kept raised to the LEON
processor until the related trap handler is run and the processor implicitly
ack the interrupt. So with the actual IRQMP code trap handler have to be run
even if the software has already done its job by clearing the pending bit.
This feature has been tested on another LEON3 simulator (tsim_leon3 from
Gaisler) and it turns out that the Qemu implementation is not equivalent to
the tsim one. In tsim, if software does clear a pending interrupt before
the related interrupt handler is triggered the said interrupt handler will
not be called.
This patch brings the Qemu IRQMP implementation in line with the tsim
implementation by allowing IRQ to be acknowledged by software only.

Commit 51f84465dd changed the compatility mode setting logic:
- machine reset only sets compatibility mode for the boot CPU
- compatibility mode is set for other CPUs when they are put online
by the guest with the "start-cpu" RTAS call
This causes a regression for machines started with max-compat-cpu:
the device tree nodes related to secondary CPU cores contain wrong
"cpu-version" and "ibm,pa-features" values, as shown below.
Guest started on a POWER8 host with:
-smp cores=2 -machine pseries,max-cpu-compat=compat7
ibm,pa-features = [18 00 f6 3f c7 c0 80 f0 80 00
00 00 00 00 00 00 00 00 80 00 80 00 80 00 00 00];
cpu-version = <0x4d0200>;
^^^
second CPU core
ibm,pa-features = <0x600f63f 0xc70080c0>;
cpu-version = <0xf000003>;
^^^
boot CPU core
The second core is advertised in raw POWER8 mode. This happens because
CAS assumes all CPUs to have the same compatibility mode. Since the
boot CPU already has the requested compatibility mode, the CAS code
does not set it for the secondary one, and exposes the bogus device
tree properties in in the CAS response to the guest.
A similar situation is observed when hot-plugging a CPU core. The
related device tree properties are generated and exposed to guest
with the "ibm,configure-connector" RTAS before "start-cpu" is called.
The CPU core is advertised to the guest in raw mode as well.
It both cases, it boils down to the fact that "start-cpu" happens too
late. This can be fixed globally by propagating the compatibility mode
of the boot CPU to the other CPUs during reset. For this to work, the
compatibility mode of the boot CPU must be set before the machine code
actually resets all CPUs.
It is not needed to set the compatibility mode in "start-cpu" anymore,
so the code is dropped.

A variable is already defined at the begining of the function to
hold a pointer to the CPU core object:
sPAPRCPUCore *core = SPAPR_CPU_CORE(OBJECT(dev));
No need to define it again in the pre-2.10 compatibility code snipplet.

We've got the config switch CONFIG_PPC4XX, so we should use it
in the Makefile accordingly and only include the PPC4xx boards
if this switch has been enabled. (Note: Unfortunately, the files
ppc4xx_devs.c and ppc405_uc.c still have to be included in the
build anyway to fulfil some complicated linker dependencies ...
so these are subject to a more thourough clean-up later)

ATA8-ACS3, 7.9 DATA SET MANAGEMENT - 06h, DMA
7.9.5 Error Outputs
If the Trim bit is set to one and:
a) the device detects an invalid LBA Range Entry; or
b) count is greater than IDENTIFY DEVICE data word 105
(see 7.16.7.55),
then the device shall return command aborted.
A device may trim one or more LBA Range Entries before it returns
command aborted. See table 209.
This check is not in the common ide_dma_cb() as the range for TRIM
is harder to reach: it is not in LBA/count registers and the buffer has
to be parsed first.

Remove dependency of possible_cpus on 1st CPU instance,
which decouples configuration data from CPU instances that
are created using that data.
Also later it would be used for enabling early cpu to numa node
configuration at runtime qmp_query_hotpluggable_cpus() should
provide a list of available cpu slots at early stage,
before machine_init() is called and the 1st cpu is created,
so that mgmt might be able to call it and use output to set
numa mapping.
Use MachineClass::possible_cpu_arch_ids() callback to set
cpu type info, along with the rest of possible cpu properties,
to let machine define which cpu type* will be used.
* for SPAPR it will be a spapr core type and for ARM/s390x/x86
a respective descendant of CPUClass.
Move parse_numa_opts() in vl.c after cpu_model is parsed into
cpu_type so that possible_cpu_arch_ids() would know which
cpu_type to use during layout initialization.
