      ppce500_mpc8544ds: Fix compile with --enable-debug and --disable-kvm · 69577857
      由 David Gibson 提交于 
      When configured with --enable-debug, we compile without optimization.
This means that the function mpc8544_copy_soc_cell() in ppce500_mpc8544ds.c
is not optimized out, even though it is never called without kvm.  That in
turn causes a link failure, because it calls the function
kvmppc_read_host_property() which is in kvm_ppc.o and therefore not
included in a --disable-kvm build.

This patch fixes the problem by providing a dummy stub for
kvmppc_read_host_property() in kvm_ppc.h when !CONFIG_KVM.

      Use existing helper function to implement popcntd instruction · 3601ff11
      由 David Gibson 提交于 
      The recent patches adding partial support for POWER7 cpu emulation included
implementing the popcntd instruction.  The support for this was open coded,
but host-utils.h already included a function implementing an equivalent
population count function, which uses a gcc builtin (which can use special
host instructions) if available.

This patch makes the popcntd implementation use the existing, potentially
faster, implementation.

      Delay creation of pseries device tree until reset · a3467baa
      由 David Gibson 提交于 
      At present, the 'pseries' machine creates a flattened device tree in the
machine->init function to pass to either the guest kernel or to firmware.

However, the machine->init function runs before processing of -device
command line options, which means that the device tree so created will
be (incorrectly) missing devices specified that way.

Supplying a correct device tree is, in any case, part of the required
platform entry conditions.  Therefore, this patch moves the creation and
loading of the device tree from machine->init to a reset callback.  The
setup of entry point address and initial register state moves with it,
which leads to a slight cleanup.

This is not, alas, quite enough to make a fully working reset for pseries.
For that we would need to reload the firmware images, which on this
machine are loaded into RAM.  It's a step in the right direction, though.

      pseries: Abolish envs array · c7a5c0c9
      由 David Gibson 提交于 
      Currently the pseries machine init code builds up an array, envs, of
CPUState pointers for all the cpus in the system.  This is kind of
pointless, given the generic code already has a perfectly good linked list
of the cpus.

In addition, there are a number of places which assume that the cpu's
cpu_index field is equal to its index in this array.  This is true in
practice, because cpu_index values are just assigned sequentially, but
it's conceptually incorrect and may not always be true.

Therefore, this patch abolishes the envs array, and explicitly uses the
generic cpu linked list and cpu_index values throughout.

      Don't call cpu_synchronize_state() from machine init. · 64a4d100
      由 Scott Wood 提交于 
      This will deadlock when the I/O thread is used, since the
CPU thread is blocked waiting for qemu_system_ready.

The synchronization is unnecessary since this is before
cpu_synchronize_all_post_init().
