2014-01-24block: rename buffer_alignment to guest_block_sizePaolo Bonzini1-1/+1
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.

2013-07-15ahci: Fix FLUSH commandKevin Wolf1-0/+9
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.

2013-06-24ide: Add handler to ide_cmd_tableKevin Wolf1-58/+86
As a preparation for moving all IDE commands into their own function like in the ATAPI code, introduce a 'handler' callback to ide_cmd_table. Commands using this new infrastructure get some things handled automatically: * The BSY flag is set before calling the handler (in order to avoid bugs like the one fixed in f68ec837) and reset on completion. * The (obsolete) DSC flag in the status register is set on completion if the command is flagged with SET_DSC in the command table * An IRQ is triggered on completion. * The error register and the ERR flag in the status register are cleared before calling the handler and on completion it is asserted that either none or both of them are set. No commands are converted at this point. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-06-06ide: Set BSY bit during FLUSHAndreas Färber1-0/+1
The implementation of the ATA FLUSH command invokes a flush at the block layer, which may on raw files on POSIX entail a synchronous fdatasync(). This may in some cases take so long that the SLES 11 SP1 guest driver reports I/O errors and filesystems get corrupted or remounted read-only. Avoid this by setting BUSY_STAT, so that the guest is made aware we are in the middle of an operation and no ATA commands are attempted to be processed concurrently. Addresses BNC#637297.

2013-04-15ide: refuse WIN_READ_NATIVE_MAX on empty deviceStefan Hajnoczi1-0/+4
What is the highest addressable sector on an empty CD-ROM? Nothing is addressable so produce an error. This patch prevents a divide-by-zero in ide_set_sector() since s->sectors and s->heads would be 0. Not to mention that a sector=-1 argument would be nonsense. Note that WIN_READ_NATIVE_MAX can be triggered using hdparm -N 1024 /dev/cdrom. The LBA bit will be set to 1 though, so the only easy way to go down the ide_set_sector() CHS code path which divides by zero is to comment out the s->select & 0x40 case for testing.

All current users (IDE, SCSI and virtio-blk) happen to share this 20 characters limit. Still, it should be left to device models. They already enforce their limits. They have to, as the DriveInfo limit only affects legacy -drive serial=..., not the qdev properties. usb-storage, which doesn't limit serial number length, also uses DriveInfo for -usbdevice.
