Non-PCI AHCI support is broken due to assertion failures when trying
to convert AHCIState to a PCIDevice pointer as AHCIState can have
different container structs. Fix this by using the non-asserting object
cast and checking the returned pointer is not NULL.
The AddressSpace pointer is also being initialized to NULL and causing
dma_memory_map call to fail. Fix this by initializing to
address_space_memory for sysbus instances.
Also correct AHCI_VMSTATE to use the correct container SysbusAHCIState
for sysbus instances.

In an ideal world, machines can be built by wiring devices together
with configuration, not code. Unfortunately, that's not the world we
live in right now. We still have quite a few devices that need to be
wired up by code. If you try to device_add such a device, it'll fail
in sometimes mysterious ways. If you're lucky, you get an
unmysterious immediate crash.
To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad. The device model is still omitted from
help, but is available anyway.
Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.
This commit clarifies no_user's purpose. Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy. While there, make it
bool.
Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale. The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.
With that done, the regression fix is hopefully acceptable.

When AHCI executes an asynchronous IDE command, it checked DRDY without
checking either DRQ or BSY. This sometimes caused interrupt to be sent
before command is actually completed.
This resulted in a race condition: if guest then managed to access the
device before command has completed, it would hang waiting for an
interrupt.
This was observed with windows 7 guests.
To fix, check for DRQ or BSY in additiona to DRDY, if set,
the command is asynchronous so delay the interrupt until
asynchronous done callback is invoked.

AHCI couldn't cope with asynchronous commands that aren't doing DMA, it
simply wouldn't complete them. Due to the bug fixed in commit f68ec837,
FLUSH commands would seem to have completed immediately even if they
were still running on the host. After the commit, they would simply hang
and never unset the BSY bit, rendering AHCI unusable on any OS sending
flushes.
This patch adds another callback for the completion of asynchronous
commands. This is what AHCI really wants to use for its command
completion logic rather than an DMA completion callback.

A DMA request can happen for data that hasn't been completely been
provided by the IDE core yet. For example
- DBDMA request for 0x1000 bytes
- IDE request for 1 sector
- DBDMA wants to read 0x1000 bytes (8 sectors) from bdrv
- breakage
Instead, we should truncate our bdrv request to the maximum number
of sectors we're allowed to read at that given time. Once that transfer
is through, we will fall into our recently introduced waiting logic.
- DBDMA requests for 0x1000 bytes
- IDE request for 1 sector
- DBDMA wants to read MIN(0x1000, 1 * 512) bytes
- DBDMA finishes reading, indicates to IDE core that transfer is complete
- IDE request for 7 sectors
- DBDMA finishes the DMA
Reported-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
Signed-off-by: Alexander Graf <agraf@suse.de>
The DBDMA engine really just reads bytes from a producing device (IDE
in our case) and shoves these bytes into memory. It doesn't care whether
any alignment takes place or not.
Our code today however assumes that block accesses always happen on
sector (512 byte) boundaries. This is a fair assumption for most cases.
However, Mac OS X really likes to do unaligned, incomplete accesses
that it finishes with the next DMA request.
So we need to read / write the unaligned bits independent of the actual
asynchronous request, because that one can only handle 512-byte-aligned
data. We also need to cache these unaligned sectors until the next DMA
request, at which point the data might be successfully flushed from the
pipe.
Signed-off-by: Alexander Graf <agraf@suse.de>
We should only start processing DMA requests when we have data to process.
Hold off working through the DMA shuffling until the IDE core told us that
it's ready.
This is required because the guest can program the DMA engine or the IDE
transfer first. Both are legal.
Signed-off-by: Alexander Graf <agraf@suse.de>
We need to know when the IDE core starts a DMA transfer. Add a notifier
