Commit 428c149b added IDEState member conf to let commit 0009baf1 find the BlockConf from there. It exists only for qdev drives, created via ide_drive_initfn(), not for drives created via ide_init2(). But for a qdev drive, we can just as well reach its IDEDevice, which contains the BlockConf. Do that, and revert the parts of commit 428c149b that add IDEState member conf. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

When cancelling a request, bdrv_aio_cancel may decide that it waits for completion of a request rather than for cancellation. IDE therefore can't abandon its DMA status before calling bdrv_aio_cancel; otherwise the callback of a completed request would use invalid data. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

The next commit will move the STOP event into do_vm_stop(), to have the expected event sequence we need to emit the I/O error event before calling vm_stop().

Add three new qdev properties to export block topology information to the guest. This is needed to get optimal I/O alignment for RAID arrays or SSDs. The options are: - physical_block_size to specify the physical block size of the device, this is going to increase from 512 bytes to 4096 kilobytes for many modern storage devices - min_io_size to specify the minimal I/O size without performance impact, this is typically set to the RAID chunk size for arrays. - opt_io_size to specify the optimal sustained I/O size, this is typically the RAID stripe width for arrays. I decided to not auto-probe these values from blkid which might easily be possible as I don't know how to deal with these issues on migration. Note that we specificly only set the physical_block_size, and not the logial one which is the unit all I/O is described in. The reason for that is that IDE does not support increasing the logical block size and at last for now I want to stick to one meachnisms in queue and allow for easy switching of transports for a given backing image which would not be possible if scsi and virtio use real 4k sectors, while ide only uses the physical block exponent. To make this more common for the different block drivers introduce a new BlockConf structure holding all common block properties and a DEFINE_BLOCK_PROPERTIES macro to add them all together, mirroring what is done for network drivers. Also switch over all block drivers to use it, except for the floppy driver which has weird driveA/driveB properties and probably won't require any advanced block options ever. Example usage for a virtio device with 4k physical block size and 8k optimal I/O size: -drive file=scratch.img,media=disk,cache=none,id=scratch \ -device virtio-blk-pci,drive=scratch,physical_block_size=4096,opt_io_size=8192 aliguori: updated patch to take into account BLOCK events Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This patch adds a new property named 'ver' to ide-drive which allows to specify the version which the virtual disk/cdrom should report to the guest. By default this is the qemu version (i.e. 0.12). usage: -drive if=none,id=disk,file=... -device ide-drive,bus=ide.0,unit=0,drive=disk,ver=42 You can also switch the version for all ide drives using: -global ide-drive.ver=42 Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Add a enable_write_cache flag in the block driver state, and use it to decide if we claim to have a volatile write cache that needs controlled flushing from the guest. The flag is off if cache=writethrough is defined because O_DSYNC guarantees that every write goes to stable storage, and it is on for cache=none and cache=writeback. Both scsi-disk and ide now use the new flage, changing from their defaults of always off (ide) or always on (scsi-disk).

The current IDE code uses an array of two IDEState structs to maintain the IDE bus. This patch adds a IDEBus to be used instead and does a bunch of cleanups: * move ide bus state from IDEState to IDEBus. * drop a bunch of ugly pointer arithmetics to figure the active interface, explicitly save the interface number instead. * add helper functions to save/restore idebus state. It also fixes a save/restore bug: loadvm allways stores the command in the master's IDEState, even when it was saved from the slave.

Introduce isa_reserve_irq() which marks an irq reserved and returns the appropriate qemu_irq entry from the i8259 table. isa_reserve_irq() is a temporary interface to be used to allocate ISA IRQs for devices which have not yet been converted to qdev, and for special cases which are not suited for qdev conversions, such as the 'ferr'. This patch goes on top of Gerd Hoffmann's which makes isa-bus.c own the ISA irq table.
