2008-09-28Change the way video graphics adapter is selectedmalc
Instead of having (current)three command line switches -std-vga, -cirrusvga and -vmwarevga, provide one -vga switch which takes an argument, so that: qemu -std-vga becomes qemu -vga std qemu -cirrusvga becomes qemu -vga cirrus qemu -vmwarevga becomes qemu -vga vmware Update documentation accordingly. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5335 c046a42c-6fe2-441c-8c8c-71466251a162
2008-09-27Make compatfd fallback more robustaliguori
Be more friendly when signalfd() fails, and also add configure checks to detect that syscall(SYS_signalfd) actually works. malc pointed out that some installs do not have /usr/include/linux headers that are in sync with the glibc headers so why SYS_signalfd is defined, it's #defined to _NR_signalfd which is not defined in the /usr/include/linux header. While this is a distro bug, it doesn't hurt to do a more thorough job in detection.

2008-09-26Implement an fd pool to get real AIO with posix-aioaliguori
This patch implements a simple fd pool to allow many AIO requests with posix-aio. The result is significantly improved performance (identical to that reported for linux-aio) for both cache=on and cache=off. The fundamental problem with posix-aio is that it limits itself to one thread per-file descriptor. I don't know why this is, but this patch provides a simple mechanism to work around this (duplicating the file descriptor). This isn't a great solution, but it seems like a reasonable intermediate step between posix-aio and a custom thread-pool to replace it. Ryan Harper will be posting some performance analysis he did comparing posix-aio with fd pooling against linux-aio. The size of the posix-aio thread pool and the fd pool were largely determined by him based on this analysis.

__GLIBC_PREREQ is defined in such a way that the ! cannot be used in front of it on FreeBSD. Also, -lpthread is not implied by the build and we definitely use it for compatfd support.

2008-09-24fix bug in block-qcow2.c:alloc_cluster_offset() (Shahar Frank)aliguori
During the debugging of the new revision of the zero dedup patch I stepped on the following bug in block-qcow2.c:alloc_cluster_offset(). I am not sure what the exact damage this bug can do, but it may be very nasty because you way not notice it effects until you will do some snapshot operations or similar actions that rely on the reference counting. The bug is easy to spot using the new "check" verb I added to the qemu-img in one of the previous patches. I will resend the qemu-img patch again with the new version of the zero dedup.

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).

2008-09-22LSI SCSI: raise UDC on infinite loop (Marcelo Tosatti)aliguori
Raise UDC (Unexpected Disconnect) when a large enough number of instructions has been executed by the SCRIPTS processor. This "solution" is much simpler than temporarily interrupting execution. This remedies the situation with Windows which downloads SCRIPTS code that busy loops on guest main memory. Their drivers _do_ handle UDC appropriately (at least XP and 2003). It would be nicer to actually detect infinite loops, but until then, this bandaid seems acceptable. Since the situation seems to be rare enough, raise the number of instructions to 10000 (previously 1000). Three people other than myself had success with this patch.
