2014-01-24block: rename buffer_alignment to guest_block_sizePaolo Bonzini
The alignment field is now set to the value that is promised to the guest, rather than required by the host. The next patches will make QEMU aware of the host-provided values, so make this clear. The alignment is also not about memory buffers, but about the sectors on the disk, change the documentation of the field. At this point, the field is set by the device emulation, but completely ignored by the block layer.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster
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.

2013-10-29ahci: fix win7 hang on bootAlexander Graf
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. Reported-by: Michael S.

2013-07-15ahci: Fix FLUSH commandKevin Wolf
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.

2013-07-11PPC: dbdma: Support more multi-issue DMA requestsAlexander Graf
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>
2013-07-11PPC: dbdma: Support unaligned DMA accessAlexander Graf
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>
2013-07-11PPC: dbdma: Wait for DMA until we have dataAlexander Graf
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>
