2008-09-10Use signalfd() to work around signal/select racealiguori
This patch introduces signalfd() to work around the signal/select race in checking for AIO completions. For platforms that don't support signalfd(), we emulate it with threads. There was a long discussion about this approach. I don't believe there are any fundamental problems with this approach and I believe eliminating the use of signals is a good thing. I've tested Windows and Linux using Windows and Linux guests. I've also checked for disk IO performance regressions.

2008-09-09Add gitignore filealiguori
While QEMU officially uses SVN, there are a number of unofficial git repositories that many developers use. Adding a .gitignore (derived from the svn:ignore) will make their lives a lot easier. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5183 c046a42c-6fe2-441c-8c8c-71466251a162
2008-09-09Fix up pxe boot (Glauber Costa)aliguori
As discussed in http://lists.gnu.org/archive/html/qemu-devel/2008-08/msg00667.html, current pxe boot is broken for some use cases. The problem goes away if we reduce the number of allowed bits in the address space to 32 (which has the side effect of reducing guest max mem size to 4Gb). After digging for a while, it turns out that it happens because pxelinux tries to access address 0x10009e9a6, which does not fit a 32-bit address. A closer look, however, reveals this access is totally valid: It's just 0x9e9a6 with an add carry. To avoid this, this patch casts the address passed to the POPL macro to a 32-bit value. This is also done, although just theorectically, for PUSHL too.
