      report issues causing the kvm probe to fail (Christian Ehrhardt) · 9fd8d8d7
      由 aliguori 提交于 
      The patch applies to upstream qemu as well as kvm-userspace, but since it is
the qemu configure script I think it should go to upstream qemu (Anthony)
first and with the next merge to kvm-userspace. On the other hand it is the kvm
probe so an ack from Avi in case v3 is ok would be reasonable.

*updates*
v2 - it also reports other errors than just #error preprocessor statements
     (requested by Avi)
v3 - In case awk or grep is not installed it now gracfully (silently)
     fails still disabling kvm (requested by Anthony)

This patch is about reporting more details of the issue if configuring kvm
fails. Therefore this patch keeps the qemu style configure output which is a
list of "$Feature $Status", but extend the "no" result like "KVM Support no"
with some more information.

There might be a lot of things going wrong with that probe and I don't want
to handle all of them, but if it is one of the known checks e.g. for
KVM_API_VERSION then we could grep/awk that out and report it. The patch
reports in case of a known case in the style
"KVM support no - (Missing KVM capability KVM_CAP_DESTROY_MEMORY_REGION_WORKS)"

In case more than one #error is triggered it creates a comma separated list in
those brackets and in case it is something else than an #error it just reports
plain old "no".

      Parse --cc and --cross-prefix earlier and use CC to determine cpu and host · ac0df51d
      由 aliguori 提交于 
      We have been relying on uname to determine the host cpu architecture and
operating system.  This is totally broken for cross compilation.  It was
workable in the past because you can manually override both settings but after
the host USB passthrough refactoring, cross host builds were broken.

This moves the parsing of --cc and --cross-prefix to before the probes for cpu
and host.  Complation testing is used to determine the host and CPU types.  I've
only added checks for i386, x86_64, Linux, and Windows since these are the only
platforms I have access to for testing.  Everything else falls back to uname.

It should be relatively easy to add the right checks for other platforms and
eliminate uname altogether.

      Make sure to link librt if we need to. · da93a1fd
      由 aliguori 提交于 
      This is really a stop-gap.  The recent thread pool changes uncovered a 
deeper issue with how we use librt.  We really should be probing for 
timer_create and then conditionally enabling that code.

      Replace posix-aio with custom thread pool · 3c529d93
      由 aliguori 提交于 
      glibc implements posix-aio as a thread pool and imposes a number of limitations.

1) it limits one request per-file descriptor.  we hack around this by dup()'ing
file descriptors which is hideously ugly

2) it's impossible to add new interfaces and we need a vectored read/write
operation to properly support a zero-copy API.

What has been suggested to me by glibc folks, is to implement whatever new
interfaces we want and then it can eventually be proposed for standardization.
This requires that we implement our own posix-aio implementation though.

This patch implements posix-aio using pthreads.  It immediately eliminates the
need for fd pooling.

It performs at least as well as the current posix-aio code (in some
circumstances, even better).
