BALATON Zoltan 4f3b0a4d75 hw/usb/vt82c686-uhci-pci: Use ISA instead of PCI interrupts
This device is part of a superio/ISA bridge chip and IRQs from it are
routed to an ISA interrupt set by the Interrupt Line PCI config
register. Implement this in a vt82c686-uhci-pci specific irq handler
Using via_isa_set_irq().

BALATON Zoltan e4f5b93986 usb/uhci: Replace pci_set_irq with qemu_set_irq
Instead of using pci_set_irq, store the irq in the device state and
use it explicitly so variants having different interrupt handling can
use their own.

Because this device only works as part of VIA superio chips set user

Philippe Mathieu-Daudé ba7b6f025b target/mips: Fix Loongson-3A4000 MSAIR config register
When using the Loongson-3A4000 CPU, the MSAIR is returned with a
zero value (because unimplemented). Checking on real hardware,
this value appears incorrect:

  $ cat /proc/cpuinfo
  system type     : generic-loongson-machine
  machine         : loongson,generic
  cpu model       : Loongson-3 V0.4  FPU V0.1
  model name      : Loongson-3A R4 (Loongson-3A4000) @ 1800MHz
  isa             : mips1 mips2 mips3 mips4 mips5 mips32r1 mips32r2 mips64r1 mips64r2
  ASEs implemented        : vz msa loongson-mmi loongson-cam loongson-ext loongson-ext2
  ...

Checking the CFCMSA opcode result with gdb we get 0x60140:

  Breakpoint 1, 0x00000001200037c4 in main ()
  1: x/i $pc
  => 0x1200037c4 <main+52>:  cfcmsa       v0,msa_ir
  (gdb) si
  0x00000001200037c8 in main ()
  (gdb) i r v0
  v0: 0x60140

MSAIR bits 17 and 18 are "reserved" per the spec revision 1.12,
so mask them out, and set MSAIR=0x0140 for the Loongson-3A4000
CPU model added in commit af868995e1.

Philippe Mathieu-Daudé 73053f6228 target/mips: Remove one MSA unnecessary decodetree overlap group
Only the MSA generic opcode was overlapping with the other
instructions. Since the previous commit removed it, we can
now remove the overlap group. The decodetree script forces
us to re-indent the opcodes.

Diff trivial to review using `git-diff --ignore-all-space`.

Note, the format definition could be named @3rf_b (for
3R with a df field BYTE-based) but since the instruction
class is named '3R', we simply call the format @3r to
ease reviewing the msa.decode file.
However we directly call the trans_msa_3rf() function,
which handles the BYTE-based df field.

with Byte vectors. Probably due to a copy/paste error, commit
7a7a162add mistakenly used the $wt (target register) instead
of $wd (destination register) as first operand. Fix that.

Damien Hedde db78a60559 machine: remove the done notifier for dynamic sysbus device type check
Now that we check sysbus device types during device creation, we
can remove the check in the machine init done notifier.
This was the only thing done by this notifier, so we remove the
whole sysbus_notifier structure of the MachineState.

Note: This notifier was checking all /peripheral and /peripheral-anon
sysbus devices. Now we only check those added by -device cli option or
device_add qmp command when handling the command/option. So if there
are some devices added in one of these containers manually (eg in
machine C code), these will not be checked anymore.
This use case does not seem to appear apart from
hw/xen/xen-legacy-backend.c (it uses qdev_set_id() and in this case,
not for a sysbus device, so it's ok).

Damien Hedde 312e1b1f3e qdev-monitor: Check sysbus device type before creating it
Add an early check to test if the requested sysbus device type
is allowed by the current machine before creating the device. This
impacts both -device cli option and device_add qmp command.

Before this patch, the check was done well after the device has
been created (in a machine init done notifier). We can now report
the error right away.

Damien Hedde b5fdf4102f machine: add device_type_is_dynamic_sysbus function
Right now the allowance check for adding a sysbus device using
-device cli option (or device_add qmp command) is done well after
the device has been created. It is done during the machine init done
notifier: machine_init_notify() in hw/core/machine.c

This new function will allow us to do the check at the right time and
issue an error if it fails.

Also make device_is_dynamic_sysbus() use the new function.

We are going to introduce an unit test for the parser smp_parse()
in hw/core/machine.c, but now machine.c is only built in softmmu.

In order to solve the build dependency on the smp parsing code and
avoid building unrelated stuff for the unit tests, move the tested
code from machine.c into a separate file, i.e., machine-smp.c and
build it in common field.
