2015-11-06ahci: split realize and initPeter Crosthwaite
Do the init level tasks asap and the realize later (mainly when num_ports is available). This allows sub-class realize routines to work with the device post-init.

2014-10-20hw: Convert from BlockDriverState to BlockBackend, mostlyMarkus Armbruster
Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member. The next two commits take care of the latter two. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-09-22ahci: MSI capability should be at 0x80, not 0x50.John Snow
In the Intel ICH9 data sheet, the MSI capability offset in the PCI configuration space for ICH9 AHCI devices is specified to be 0x80. Further, the PCI capability pointer should always point to 0x80 in ICH9 devices, despite the fact that AHCI 1.3 specifies that it should be pointing to PMCAP (Which in this instance would be 0x70) to maintain adherence to the Intel data sheet specifications and real observed behavior.

After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

Many of these should be cleaned up with proper qdev-/QOM-ification.

2013-01-10Make all static TypeInfos constAndreas Färber
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2012-06-27ide/ahci: Use universal DMA helper functionsDavid Gibson
The AHCI device can provide both PCI and SysBus AHCI device emulations. For this reason, it wasn't previously converted to use the pci_dma_*() helper functions. Now that we have universal DMA helper functions, this converts AHCI to use them. The DMAContext is obtained from pci_dma_context() in the PCI case and set to NULL in the SysBus case (i.e. we assume for now that a SysBus AHCI has no IOMMU translation).

2012-02-03qdev: remove baked in notion of aliases (v2)Anthony Liguori
Limit them to the device_add functionality. Device aliases were a hack based on the fact that virtio was modeled the wrong way. The mechanism for aliasing is very limited in that only one alias can exist for any device. We have to support it for the purposes of compatibility but we only need to support it in device_add so restrict it to that piece of code.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
