2008-10-08Fix IO performance regression in sparcaliguori
Replace signalfd with signal handler/pipe. There is no way to interrupt the CPU execution loop when a file descriptor becomes readable. This results in a large performance regression in sparc emulation during bootup. This patch switches us to signal handler/pipe which was originally suggested by Ian Jackson. The signal handler lets us interrupt the CPU emulation loop while the write to a pipe lets us avoid the select/signal race condition.

2008-09-29Add a virtual HCI.balrog
This implements most of the logic of a real HCI (at least the pieces marked as mandatory). It doesn't support keys, authentication etc. It works on top of the LMP layer, which is not fully emulated because software never has direct access to it. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5345 c046a42c-6fe2-441c-8c8c-71466251a162
2008-09-28Implement a HCI passthrough to host.balrog
This allows using a host's physical HCI as one of the HCIs attached to the virtual machine. This brings various limitations because not all commands/events are passed through by Linux kernel, some are interpreted by the host's kernel for a speed gain. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5344 c046a42c-6fe2-441c-8c8c-71466251a162

2008-09-22Refactor AIO to allow multiple AIO implementationsaliguori
This patch refactors the AIO layer to allow multiple AIO implementations. It's only possible because of the recent signalfd() patch. Right now, the AIO infrastructure is pretty specific to the block raw backend. For other block devices to implement AIO, the qemu_aio_wait function must support registration. This patch introduces a new function, qemu_aio_set_fd_handler, which can be used to register a file descriptor to be called back. qemu_aio_wait() now polls a set of file descriptors registered with this function until one becomes readable or writable. This patch should allow the implementation of alternative AIO backends (via a thread pool or linux-aio) and AIO backends in non-traditional block devices (like NBD).

2008-09-15Use common objects for qemu-img and qemu-nbdaliguori
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the code. It's ugly and causes us to have to build multiple object files for linking against qemu and the tools. This patch introduces a new file, qemu-tool.c which contains enough for qemu-img, qemu-nbd, and QEMU to all share the same objects. This also required getting qemu-nbd to be a bit more Windows friendly. I also changed the Windows block-raw to use normal IO instead of overlapping IO since we don't actually do AIO yet on Windows. I changed the various #if 0's to #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows. After this patch, there are no longer any #ifdef's related to qemu-img and qemu-nbd.

2008-09-11Only build compatfd when using AIO and make sure to always init AIOaliguori
OpenBSD doesn't use AIO so don't try to build compatfd when not using AIO. Also make sure to call qemu_aio_init() from bdrv_init. Everything that uses bdrv calls bdrv_init so it makes sense to init aio from there instead of in every single tool.

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.

2008-08-21Fix windows buildaliguori
Right now, the Windows build is broken because of NBD. Using a mingw32 cross compiler is also badly broken. This patch fixes the Windows build by stubbing out NBD support until someone fixes it for Windows. It also santizing the mingw32 cross compiler support by replacing the --enable-mingw32 option with a compiler check to determine if we're on windows or not. Also remove the weird SDL pseudo-detection for mingw32 using a cross compiler. The hardcoded sdl-config name is seemly arbitrary. If you cross compiler SDL correctly and modify your PATH variable appropriately, it will Just Work when cross compiling. The audio driver detection is also broken for cross compiling so you have to specify the audio drivers explicitly for now.

2008-08-02Fix compilation of nbd on Solaris (Andreas Faerber)aliguori
Compilation of QEMU is currently broken on Solaris due to nbd's use of _IO and due to network libraries not being linked into qemu-img. The attached patch adds the appropriate libraries (copied from Makefile.target) and includes an additional Sun-specific header for _IO. With these fixes it compiles okay, on OpenSolaris snv_93 (amd64).
