      PPC: Mac: Move tbfreq into local variable · caae6c96
      由 Alexander Graf 提交于 
      We already expose the real CPU's tb frequency to the guest via fw_cfg. Soon
we will need to also expose it to the MacIO, so let's move it to a variable
that we can leverage every time we need the frequency.

      PPC: mac99: Move NVRAM to page boundary when necessary · 261265cc
      由 Alexander Graf 提交于 
      When running KVM we have to adhere to host page boundaries for memory slots.
Unfortunately the NVRAM on mac99 is a 4k RAM hole inside of an MMIO flash
area.

So if our host is configured with 64k page size, we can't use the mac99 target
with KVM. This is a real shame, as this limitation is not really an issue - we
can easily map NVRAM somewhere else and at least Linux and Mac OS X use it
at their new location.

So in that emergency case when it's about failing to run at all and moving NVRAM
to a place it shouldn't be at, choose the latter.

This patch enables -M mac99 with KVM on 64k page size hosts.

      PPC: KVM: Fix g3beige and mac99 when HV is loaded · 277c7a4d
      由 Alexander Graf 提交于 
      On PPC we have 2 different styles of KVM: PR and HV. HV can only virtualize
sPAPR guests while PR can virtualize everything that's reasonably close to
the host hardware platform.

As long as only one kernel module (PR or HV) is loaded, the "default" kvm type
is the module that's loaded. So if your hardware only supports PR mode you can
easily spawn a Mac VM.

However, if both HV and PR are loaded we default to HV mode. And in that case
the Mac machines have to explicitly ask for PR mode to get a working VM.

Fix this up by explicitly having the Mac machines ask for PR style KVM. This
fixes bootup of Mac VMs on systems where bot HV and PR kvm modules are loaded
for me.

      ppc: fix -mem-path failure · e206ad48
      由 Hu Tao 提交于 
      commit e938ba0c tried to enable -mem-path for ppc but breaked some ppc
boards.

The problems are:

1. it fails when allocating memory for rom, sram whose sizes are less
   than huge page size:

   ./ppc-softmmu/qemu-system-ppc  -m 512 -mem-path /hugepages/ \
   -kernel /home/hutao/Downloads/vmlinux-ppc -initrd \
   /home/hutao/Downloads/initrd-ppc.gz
   qemu-system-ppc: /mnt/data/projects/qemu/exec.c:1184: qemu_ram_set_idstr: Assertion `new_block' failed.

2. if there is a numa node backed by memory backend object, qemu fails
   with message:

   ./ppc-softmmu/qemu-system-ppc  -m 512 \
   -object memory-backend-file,size=512M,mem-path=/hugepages,id=f0 \
   -numa node,nodeid=0,memdev=f0 \
   -kernel /home/hutao/Downloads/vmlinux-ppc \
   -initrd /home/hutao/Downloads/initrd-ppc.gz
   qemu-system-ppc: memory backend f0 is used multiple times. Each -numa option must use a different memdev value.

This patch does following:

1. replaces memory_region_allocate_system_memory() with
   memory_region_init_ram() for rom, sram. Then only system memory
   is backed by hugepages when specifying mem-path.

2. for memory banks, allocates all ram with
   one memory_region_allocate_system_memory(), and use
   memory_region_init_alias() to initialize memory banks.

Tested machines: default(g3beige), mac99, taihu, bamboo, ref405ep.

      mac99: Add motherboard devices before PCI cards · a0bb2a5f
      由 BALATON Zoltan 提交于 
      Change the order of creating devices for New World Mac emulation so
that devices on the motherboard are added first and PCI cards (VGA and
NIC) come later. As a side effect, this also causes OpenBIOS to map
the motherboard devices into the MMIO space to the same addresses as
on real hardware and allow clients that hardcode these addresses (e.g.
MorphOS) to find and use them until OpenBIOS is tought to map devices
to specific addresses. (On real hardware the graphics and network
cards are really on separate buses but we don't model that yet.) This
brings the memory map closer to what is found on PowerMac3,1.

      hw: Clean up bogus default boot order · c1654732
      由 Markus Armbruster 提交于 
      We set default boot order "cad" in every single machine definition
except "pseries" and "moxiesim", even though very few boards actually
care for boot order, and "cad" makes sense for even fewer.

Machines that care:

* pc and its variants

  Accept up to three letters 'a', 'b' (undocumented alias for 'a'),
  'c', 'd' and 'n'.  Reject all others (fatal with -boot).

* nseries (n800, n810)

  Check whether order starts with 'n'.  Silently ignored otherwise.

* prep, g3beige, mac99

  Extract the first character the machine understands (subset of
  'a'..'f').  Silently ignored otherwise.

* spapr

  Accept an arbitrary string (vl.c restricts it to contain only
  'a'..'p', no duplicates).

* sun4[mdc]

  Use the first character.  Silently ignored otherwise.

Strip characters these machines ignore from their default boot order.

For all other machines, remove the unused default boot order
alltogether.

Note that my rename of QEMUMachine member boot_order to
default_boot_order and QEMUMachineInitArgs member boot_device to
boot_order has a welcome side effect: it makes every use of boot
orders visible in this patch, for easy review.

      pci: Add root bus parameter to pci_nic_init() · 29b358f9
      由 David Gibson 提交于 
      At present, pci_nic_init() and pci_nic_init_nofail() assume that they will
only create a NIC under the primary PCI root.  As we add support for
multiple PCI roots, that may no longer be the case.  This patch adds a root
bus parameter to pci_nic_init() (and updates callers accordingly) to allow
the machine init code using it to specify the right PCI root for NICs
created by old-style -net nic parameters.  NICs created new-style, with
-device can of course be put anywhere.

      PPC: mac newworld: fix cpu NIP reset value · 20f649dd
      由 Alexander Graf 提交于 
      On -M mac99, we can run 970 CPUs. However, these CPUs define the initial
instruction pointer they start execution at as part of their bootup protocol,
so effectively it's up to the board to decide where they start.

This went unnoticed, because they used to boot at the same location our flash
was mapped to, but due to the recent reset changes our 970 CPUs want to reset
to 0x100 now, which is always a 0 instruction.

Set the initial IP to something reasonable for -M mac99.

      Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

      openpic: convert to qdev · d0b72631
      由 Alexander Graf 提交于 
      This patch converts the OpenPIC device to qdev. Along the way it
renames the "openpic" target to "raven" and the "mpic" target to
"fsl_mpic_20", to better reflect the actual models they implement.

This way we have a generic OpenPIC device now that can handle
different flavors of the OpenPIC specification.

      Add USB option in machine options · 094b287f
      由 zhlcindy@gmail.com 提交于 
      When -usb option is used, global varible usb_enabled is set.
And all the plaform will create one USB controller according
to this variable. In fact, global varibles make code hard
to read.

So this patch is to remove global variable usb_enabled and
add USB option in machine options. All the plaforms will get
USB option value from machine options.

USB option of machine options will be set either by:
  * -usb
  * -machine type=pseries,usb=on

Both these ways can work now. They both set USB option in
machine options. In the future, the first way will be removed.
