VERIFY command is like a READ command, except that read data is not transfered by DMA. As DMA engine is not used, so we have to start data transfer ourselves. Signed-off-by: NHervé Poussineau <hpoussin@reactos.org> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

fdctrl_start_transfer() used to set FD_SR0_SEEK no matter if there actually was a seek or not. This is obviously wrong. fdctrl_start_transfer() has this information because it performs the initial seek itself.

It decided whether an interrupt is triggered. Only one caller made use of this functionality, so move the code there. In this one caller, the interrupt must actually be triggered unconditionally, like it was before commit 2fee0088. For example, a successful read without an implied seek can result in st0 = 0, but still triggers the interrupt.

Now that AIOPool no longer keeps a freelist, it isn't really a "pool" anymore. Rename it to AIOCBInfo and make it const since it no longer needs to be modified. Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

由 Stefan Hajnoczi 提交于
AIO control blocks are frequently acquired and released because each aio request involves at least one AIOCB. Therefore, we pool them to avoid heap allocation overhead. The problem with the freelist approach in AIOPool is thread-safety. If we want BlockDriverStates to associate with AioContexts that execute in multiple threads, then a global freelist becomes a problem. This patch drops the freelist and instead uses g_slice_alloc() which is tuned for per-thread fixed-size object pools. qemu_aio_get() and qemu_aio_release() are now thread-safe. Note that the change from g_malloc0() to g_slice_alloc() should be safe since the freelist reuse case doesn't zero the AIOCB either.

To do this, we start a qemu-nbd process at _make_test_img and kill it in _cleanup_test_img. $TEST_IMG is changed to point at the TCP server. We also remove the checks for existence of binaries from common.config - they're duplicated in common, and we can make the qemu-nbd check conditional on $IMGPROTO being "nbd" if we do it there.

Versions before gcc-4.6 don't support unnamed fields in initializers (see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676). Offset and OffsetHigh belong to an unnamed struct which is part of an unnamed union. Therefore the original code does not work with older versions of gcc.

This makes use of the new level irqfd support enabling bypass of qemu userspace both on INTx injection and unmask. This significantly boosts the performance of devices making use of legacy interrupts (ex. ~60% better netperf TCP_RR scores for an e1000e assigned to a Linux guest and booted with pci=nomsi). This also avoids flipping mmaps on and off to simulate EOIs, so greatly improves performance of device access in addition to interrupt latency.

Commit ed2aec4867f0d5f5de496bb765347b5d0cfe113d changed the return value of aio_ctx_prepare from false to true when only idle bottom halves are available. This broke PC old-style DMA, which uses them. Fix this by making aio_ctx_prepare return true only when non-idle bottom halves are scheduled to run.

Define a new global dma_context_memory which is a DMAContext corresponding to the global address_space_memory AddressSpace. This can be used by sysbus peripherals like sysbus-ohci which need to do DMA. In particular, use it in the sysbus-ohci device, which fixes a segfault when attempting to use that device.
