David Hildenbrand 1b6d6af21b pc-dimm: factor out capacity and slot checks into MemoryDevice
Move the checks into memory_device_get_free_addr(). This will check
before doing any calculations if we have KVM/vhost slots left and if
the total region size would be exceeded.

Of course, while at it, make it independent of pc-dimm code.

David Hildenbrand bb0831bdf4 pc-dimm: factor out address search into MemoryDevice code
This mainly moves code, but does a handfull of optimizations:
- We pass the machine instead of the address space properties
- We check the hinted address directly and handle fragmented memory
  better
- We make the search independent of pc-dimm

David Hildenbrand acc7fa17e6 pc-dimm: no need to pass the memory region
We can just query it ourselves. When unplugging, we should always be
able to the region (as it was previously plugged). E.g. PPC already
assumed that and used &error_abort.

David Hildenbrand b0c14ec4ef machine: make MemoryHotplugState accessible via the machine
Let's allow to query the MemoryHotplugState directly from the machine.
If the pointer is NULL, the machine does not support memory devices. If
the pointer is !NULL, the machine supports memory devices and the
data structure contains information about the applicable physical
guest address space region.

This allows us to generically detect if a certain machine has support
for memory devices, and to generically manage it (find free address
range, plug/unplug a memory region).

We will rename "MemoryHotplugState" to something more meaningful
("DeviceMemory") after we completed factoring out the pc-dimm code into
MemoryDevice code.

David Hildenbrand 2cc0e2e814 pc-dimm: factor out MemoryDevice interface
On the qmp level, we already have the concept of memory devices:
    "query-memory-devices"
Right now, we only support NVDIMM and PCDIMM.

We want to map other devices later into the address space of the guest.
Such device could e.g. be virtio devices. These devices will have a
guest memory range assigned but won't be exposed via e.g. ACPI. We want
to make them look like memory device, but not glued to pc-dimm.

Especially, it will not always be possible to have TYPE_PC_DIMM as a parent
class (e.g. virtio devices). Let's use an interface instead. As a first
part, convert handling of
- qmp_pc_dimm_device_list
- get_plugged_memory_size
to our new model. plug/unplug stuff etc. will follow later.

A memory device will have to provide the following functions:
- get_addr(): Necessary, as the property "addr" can e.g. not be used for
              virtio devices (already defined).
- get_plugged_size(): The amount this device offers to the guest as of
                      now.
- get_region_size(): Because this can later on be bigger than the
                     plugged size.
- fill_device_info(): Fill MemoryDeviceInfo, e.g. for qmp.

Under PAPR, only the boot CPU is active when the system starts.  Other cpus
must be explicitly activated using an RTAS call.  The entry state for the
boot and secondary cpus isn't identical, but it has some things in common.

make a helper which sets up the common entry state for both boot and

Thomas Huth 052888f043 hw/s390x: Allow to configure the consoles with the "-serial" parameter
The consoles ("sclpconsole" and "sclplmconsole") can only be configured
with "-device" and "-chardev" so far. Other machines use the convenience
option "-serial" to configure the default consoles, even for virtual
consoles like spapr-vty on the pseries machine. So let's support this
option on s390x, too. This way we can easily enable the serial console
here again with "-nodefaults", for example:

qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio

... which is way shorter than typing:

qemu-system-s390x -no-shutdown -nographic -nodefaults \
  -chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \
  -mon chardev=c1

The -serial parameter can also be used if you only want to see the QEMU
monitor on stdio without using -nodefaults, but not the console output.
That's something that is pretty impossible with the current code today:

qemu-system-s390x -no-shutdown -nographic -serial none

While we're at it, this patch also maps the second -serial option to the
"sclplmconsole", so that there is now an easy way to configure this second
console on s390x, too, for example:

qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio

Additionally, the new code is also smaller than the old one and we have
less s390x-specific code in vl.c :-)

I've also checked that migration still works as expected by migrating
a guest with console output back and forth between a qemu-system-s390x
that has this patch and an instance without this patch.

Ross Lagerwall 2cbf890353 xen: Use newly added dmops for mapping VGA memory
Xen unstable (to be in 4.11) has two new dmops, relocate_memory and
pin_memory_cacheattr. Use these to set up the VGA memory, replacing the
previous calls to libxc. This allows the VGA console to work properly
when QEMU is running restricted (-xen-domid-restrict).

Wrapper functions are provided to allow QEMU to work with older versions
of Xen.

Tweak the error handling while making this change:
* Report pin_memory_cacheattr errors.
* Report errors even when DEBUG_HVM is not set. This is useful for
trying to understand why VGA is not working, since otherwise it just
fails silently.
* Fix the return values when an error occurs. The functions now
consistently return -1 and set errno.

Trent Piepho 478a573a7d i.MX: Support serial RS-232 break properly
Linux does not detect a break from this IMX serial driver as a magic
sysrq.  Nor does it note a break in the port error counts.

The former is because the Linux driver uses the BRCD bit in the USR2
register to trigger the RS-232 break handler in the kernel, which is
where sysrq hooks in.  The emulated UART was not setting this status
bit.

The latter is because the Linux driver expects, in addition to the BRK
bit, that the ERR bit is set when a break is read in the FIFO.  A break
should also count as a frame error, so add that bit too.

Peter Maydell 0fd74f03ed hw/arm/bcm2836: Create proper bcm2837 device
The bcm2837 is pretty similar to the bcm2836, but it does have
some differences. Notably, the MPIDR affinity aff1 values it
sets for the CPUs are 0x0, rather than the 0xf that the bcm2836
uses, and if this is wrong Linux will not boot.

Rather than trying to have one device with properties that
configure it differently for the two cases, create two
separate QOM devices for the two SoCs. We use the same approach
as hw/arm/aspeed_soc.c and share code and have a data table
that might differ per-SoC. For the moment the two types don't
actually have different behaviour.

the names which are visible via the header file to the

This is a preliminary to making bcm283x be an abstract
parent class to specific types for the bcm2836 and bcm2837.

Guenter Roeck 6461d7e267 fsl-imx6: Swap Ethernet interrupt defines
The sabrelite machine model used by qemu-system-arm is based on the
Freescale/NXP i.MX6Q processor. This SoC has an on-board ethernet
controller which is supported in QEMU using the imx_fec.c module
(actually called imx.enet for this model.)

The include/hw/arm/fsm-imx6.h file defines the interrupt vectors for the
imx.enet device like this:

 #define FSL_IMX6_ENET_MAC_1588_IRQ 118
 #define FSL_IMX6_ENET_MAC_IRQ 119

According to https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf,
page 225, in Table 3-1. ARM Cortex A9 domain interrupt summary,
interrupts are as follows.

150 ENET MAC 0 IRQ
151 ENET MAC 0 1588 Timer interrupt

where

150 - 32 == 118
151 - 32 == 119

In other words, the vector definitions in the fsl-imx6.h file are reversed.

Fixing the interrupts alone causes problems with older Linux kernels:
The Ethernet interface will fail to probe with Linux v4.9 and earlier.
Linux v4.1 and earlier will crash due to a bug in Ethernet driver probe
error handling. This is a Linux kernel problem, not a qemu problem:
the Linux kernel only worked by accident since it requested both interrupts.

For backward compatibility, generate the Ethernet interrupt on both interrupt
lines. This was shown to work from all Linux kernel releases starting with
v3.16.

Igor Mammedov 2278b93941 Use cpu_create(type) instead of cpu_init(cpu_model)
With all targets defining CPU_RESOLVING_TYPE, refactor
cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model)
so that callers won't have to know internal resolving cpu
type. Place it in exec.c so it could be called from both
target independed vl.c and *-user/main.c.

That allows us to stop abusing cpu type from
  MachineClass::default_cpu_type
as resolver class in vl.c which were confusing part of
cpu_parse_cpu_model().

Also with new parse_cpu_model(), the last users of cpu_init()
in null-machine.c and bsd/linux-user targets could be switched
to cpu_create() API and cpu_init() API will be removed by
follow up patch.

With no longer users left remove MachineState::cpu_model field,
new code should use MachineState::cpu_type instead and
leave cpu_model parsing to generic code in vl.c.

qemu-system-ppc64: -cdrom x.iso: machine type does not support if=scsi,bus=0,unit=2

Fix it by providing a lsi53c810_create() function that takes care
of calling scsi_bus_legacy_handle_cmdline() after creating the
corresponding SCSI controller.
