      kvm: Fix memory slot page alignment logic · f2a64032
      由 Alexander Graf 提交于 
      Memory slots have to be page aligned to get entered into KVM. There
is existing logic that tries to ensure that we pad memory slots that
are not page aligned to the biggest region that would still fit in the
alignment requirements.

Unfortunately, that logic is broken. It tries to calculate the start
offset based on the region size.

Fix up the logic to do the thing it was intended to do and document it
properly in the comment above it.

With this patch applied, I can successfully run an e500 guest with more
than 3GB RAM (at which point RAM starts overlapping subpage memory regions).

      accel: Rename 'init' method to 'init_machine' · 0d15da8e
      由 Eduardo Habkost 提交于 
      Today, all accelerator init functions affect some global state:
* tcg_init() calls tcg_exec_init() and affects globals such as tcg_tcx,
  page size globals, and possibly others;
* kvm_init() changes the kvm_state global, cpu_interrupt_handler, and possibly
  others;
* xen_init() changes the xen_xc global, and registers a change state handler.

With the new accelerator QOM classes, initialization may now be split in two
steps:
* instance_init() will do basic initialization that doesn't affect any global
  state and don't need MachineState or MachineClass data. This will allow
  probing code to safely create multiple accelerator objects on the fly just
  for reporting host/accelerator capabilities, for example.
* accel_init_machine()/init_machine() will save the accelerator object in
  MachineState, and do initialization steps which still affect global state,
  machine state, or that need data from MachineClass or MachineState.

To clarify the difference between those two steps, rename init() to
init_machine().

      accel: Move KVM accel registration to kvm-all.c · 782c3f29
      由 Eduardo Habkost 提交于 
      Note that this has an user-visible side-effect: instead of reporting
"KVM is not supported for this target", QEMU binaries not supporting KVM
will report "kvm accelerator does not exist".

As kvm_availble() always return 1 when CONFIG_KVM is enabled, we don't
need to set AccelClass.available anymore. kvm_enabled() is not being
completely removed yet only because qmp_query_kvm() still uses it.

This also allows us to make kvm_init() static.

      kvm: Allow arch to set sigmask length · aed6efb9
      由 James Hogan 提交于 
      MIPS/Linux is unusual in having 128 signals rather than just 64 like
most other architectures. This means its sigmask is 16 bytes instead of
8, so allow arches to override the sigmask->len value passed to the
KVM_SET_SIGNAL_MASK ioctl in kvm_set_signal_mask() by calling
kvm_set_sigmask_len() from kvm_arch_init(). Otherwise default to 8
bytes.

      KVM: Fix GSI number space limit · 00008418
      由 Alexander Graf 提交于 
      KVM tells us the number of GSIs it can handle inside the kernel. That value is
basically KVM_MAX_IRQ_ROUTES. However when we try to set the GSI mapping table,
it checks for

    r = -EINVAL;
    if (routing.nr >= KVM_MAX_IRQ_ROUTES)
        goto out;

erroring out even when we're only using all of the GSIs. To make sure we never
hit that limit, let's reduce the number of GSIs we get from KVM by one.

      Revert "fix return check for KVM_GET_DIRTY_LOG ioctl" · 50212d63
      由 Michael Tokarev 提交于 
      This reverts commit b533f658.

The original code was wrong, because effectively it ignored errors
from kernel, because kernel does not return -1 on error case but
returns -errno, and does not return -EPERM for this particular ioctl.
But in some cases kernel actually returned unsuccessful result,
namely, when the dirty bitmap in requested slot does not exist
it returns -ENOENT.  With new code this condition becomes an
error when it shouldn't be.

Revert that patch instead of fixing it properly this late in the
release process.  I disagree with this approach, but let's make
things move _somewhere_, instead of arguing endlessly whch of
the 2 proposed fixes is better.
