*	Revert "Get rid of _t suffix"	Anthony Liguori	2009-10-01	1	-4/+4
\| \| \| \| \| \| \| \| \| \| \| \|	In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

*	Get rid of _t suffix	malc	2009-10-01	1	-4/+4
\| \| \| \| \| \| \|	Some not so obvious bits, slirp and Xen were left alone for the time being. Signed-off-by: malc <av1474@comtv.ru>
*	fully split aio_pool from BlockDriver	Christoph Hellwig	2009-05-27	1	-17/+15
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Now that we have a separate aio pool structure we can remove those aio pool details from BlockDriver. Every driver supporting AIO now needs to declare a static AIOPool with the aiocb size and the cancellation method. This cleans up the current code considerably and will make it cleaner and more obvious to support two different aio implementations behind a single BlockDriver.

*	Fix DMA API when handling an immediate error from block layer (Avi Kivity)	aliguori	2009-03-28	1	-6/+21
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The block layer may signal an immediate error on an asynchronous request by returning NULL. The DMA API did not handle this correctly, returning an AIO request which would never complete (and which would crash if cancelled). Fix by detecting the failure and propagating it.

*	Move block dma helpers aiocb to store dma state (Avi Kivity)	aliguori	2009-03-20	1	-17/+20
\| \| \| \| \| \| \| \| \| \| \|	Use the dedicated dma aiocb to store intermediate state for dma block transactions.

*	Implement cancellation method for dma async I/O (Avi Kivity)	aliguori	2009-03-20	1	-1/+14
\| \| \| \| \| \| \| \| \| \| \| \|	Move the dma helpers to a private aio pool, and implement a cancellation method for them. Should prevent issues when cancelling I/O while dma is in progress.

*	Introduce block dma helpers (Avi Kivity)	aliguori	2009-02-05	1	-1/+118
\| \| \| \| \| \| \| \| \| \| \| \|	These helpers perform read/write requests on entire scatter/gather lists, relieving the device emulation code from mapping and unmapping physical memory, and from looping when map resources are exhausted.

*	Add a scatter-gather list type and accessors (Avi Kivity)	aliguori	2009-02-05	1	-0/+38
	Scatter-gather lists are used extensively in dma-capable devices; a single data structure allows more code reuse later on.
