The MIPS TCG backend is the only one to have
tcg_target_reg_alloc_order[] elements of type TCGReg rather than int.
This resulted in commit 91478cefaaf2 ("tcg: Allocate indirect_base
temporaries in a different order") breaking the build on MIPS since the
type differed from indirect_reg_alloc_order[]

ide_atapi_dma_restart() used to just complete the DMA with an error,
under the assumption that there isn't enough information to restart it.
However, as the contents of the ->io_buffer is preserved, it looks safe to
just re-evaluate it and dispatch the ATAPI command again.
From: Pavel Butsykin
Restart of ATAPI DMA used to be unreachable, because the request to do
so wasn't indicated in bus->error_status due to the lack of spare bits, and
ide_restart_bh() would return early doing nothing.
This patch makes use of the observation that not all bit combinations were

This patch set fixes bugs in the IDE DMA and the IDE ATAPI on operations to

If the migration occurs after the IDE DMA has been set up but before it

This might actually fix GPU passthrough for Nvidia cards when Hyper-V is
enabled.

Using the nested aio_poll() in coroutine is a bad idea. This patch
replaces the aio_poll loop in bdrv_drain with a BH, if called in
coroutine.
For example, the bdrv_drain() in mirror.c can hang when a guest issued
request is pending on it in qemu_co_mutex_lock().
Mirror coroutine in this case has

In addition to handling IO in vcpu thread and in io thread, dataplane
introduces yet another mode: handling it by aio.
This reuses the same handler as previous modes, which triggers races as
these were not designed to be reentrant.
Use a separate handler just for aio,
Reentrancy cannot happen while the BQL is being held.
