[Qemu-devel] IO thread in SVN

[Qemu-devel] IO thread in SVN

[Anthony Liguori]

Hi,

I've committed Marcelo's IO thread patch series.  The IO thread is 
disabled by default and I've done a fair bit of testing to validate that 
it doesn't regress when disabled.  I'm only able to do a small amount of 
Windows testing (the current build SEGVs in Wine) but it looks to be 
okay on Windows too.

I'd eventually like to get to the point where we enable the IO thread by 
default but we have some work to do to get there.

If you experience any kind of slow downs or freezes, please let me 
know.  I'd recommend starting bisects before the IO thread.

It doesn't compile here on MinGW with pthreads-w32:
