      trace: provide mechanism for registering trace events · fe4db84d
      由 Daniel P. Berrange 提交于 
      Remove the notion of there being a single global array
of trace events, by introducing a method for registering
groups of events.

The module_call_init() needs to be invoked at the start
of any program that wants to make use of the trace
support. Currently this covers system emulators qemu-nbd,
qemu-img and qemu-io.

[Squashed the following fix from Daniel P. Berrange
<berrange@redhat.com>:

linux-user/bsd-user: initialize trace events subsystem

The bsd-user/linux-user programs make use of the CPU emulation
code and this now requires that the trace events subsystem
is enabled, otherwise it'll crash trying to allocate an empty
trace events bitmap for the CPU object.

      log: Fix qemu_set_log_filename() error handling · daa76aa4
      由 Markus Armbruster 提交于 
      When qemu_set_log_filename() detects an invalid file name, it reports
an error, closes the log file (if any), and starts logging to stderr
(unless daemonized or nothing is being logged).

This is wrong.  Asking for an invalid log file on the command line
should be fatal.  Asking for one in the monitor should fail without
messing up an existing logfile.

Fix by converting qemu_set_log_filename() to Error.  Pass it
&error_fatal, except for hmp_logfile report errors.

This also permits testing without a subprocess, so do that.

      Revert "bsd-user: replace fprintf(stderr, ...) with error_report()" · 9bb93180
      由 Peter Maydell 提交于 
      This reverts commit 1fba5095.

That commit converted various fprintf(stderr, ...) calls to
use error_report(); however none of these bsd-user files include
a header which gives a prototype for error_report, so this
causes compiler warnings. Since these are just straightforward
reporting of command line errors, we should handle these in the
obvious way by printing to stderr, as we do for linux-user.
There's no need to drag in the error-handling framework for this,
especially since user-mode doesn't have the "maybe we need to
send this to the monitor" issues system emulation does.

      target-i386: Replace cpuid_*features fields with a feature word array · 0514ef2f
      由 Eduardo Habkost 提交于 
      This replaces the feature-bit fields on both X86CPU and x86_def_t
structs with an array.

With this, we will be able to simplify code that simply does the same
operation on all feature words (e.g. kvm_check_features_against_host(),
filter_features_for_kvm(), add_flagname_to_bitmaps(), CPU feature-bit
property lookup/registration, and the proposed "feature-words" property)

The following field replacements were made on X86CPU and x86_def_t:

  (cpuid_)features         -> features[FEAT_1_EDX]
  (cpuid_)ext_features     -> features[FEAT_1_ECX]
  (cpuid_)ext2_features    -> features[FEAT_8000_0001_EDX]
  (cpuid_)ext3_features    -> features[FEAT_8000_0001_ECX]
  (cpuid_)ext4_features    -> features[FEAT_C000_0001_EDX]
  (cpuid_)kvm_features     -> features[FEAT_KVM]
  (cpuid_)svm_features     -> features[FEAT_SVM]
  (cpuid_)7_0_ebx_features -> features[FEAT_7_0_EBX]
