2014-10-31megasas: Rework frame queueing algorithmHannes Reinecke
Windows requires the frames to be unmapped, otherwise we run into a race condition where the updated frame data is not visible to the guest. With that we can simplify the queue algorithm and use a bitmap for tracking free frames. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31megasas: Update queue loggingHannes Reinecke
Improve queue logging by displaying head and tail pointer of the completion queue. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31megasas: Implement DCMD_CLUSTER_RESET_LDHannes Reinecke
Some implementations use DCMD_CLUSTER_RESET_LD to simulate a device reset. Signed-off-by: Hannes Reinecke <hare@suse.de> [Compare against id, not lun. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31megasas: Ignore duplicate init_firmware commandsHannes Reinecke
The windows driver is sending several init_firmware commands when in MSI-X mode. It is, however, using only the first queue. So disregard any additional init_firmware commands until the HBA is reset. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31megasas: Clear unit attention on initial resetHannes Reinecke
The EFI firmware doesn't handle unit attentions properly, so we need to clear the Power On/Reset unit attention upon initial reset. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31megasas: Decode register namesHannes Reinecke
To ease debugging we should be decoding the register names. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-10-31megasas: add MegaRAID SAS 2108 emulationHannes Reinecke
The 2108 chip supports MSI and MSI-X, so update the emulation to support both chips. Signed-off-by: Hannes Reinecke <hare@suse.de> [Make VMStateDescription const. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31megasas: fixup device mappingHannes Reinecke
Logical drives can only be addressed with the 'target_id' number; LUN numbers cannot be selected. Physical drives can be selected with both, target and LUN id. So we should disallow LUN numbers not equal to 0 when in RAID mode. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-10-31megasas: fixup MFI_DCMD_LD_LIST_QUERYHannes Reinecke
The MFI_DCMD_LD_LIST_QUERY function is using a different format than MFI_DCMD_LD_LIST, so we need to implement it differently. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
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>

2014-06-18megasas: use PCI DMA APIPaolo Bonzini
MegaSAS emulation is not IOMMU-friendly. Fix this by switching to pci_dma_* functions. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-16savevm: Remove all the unneeded version_minimum_id_old (x86)Juan Quintela
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.

2014-05-20megasas: remove buildtime stringsOlaf Hering
Using __DATE__ or __TIME__ in binary pkgs changes the checksum of compiled binaries if they get rebuilt, even if there are no other source changes.

2014-04-28megasas: Implement LD_LIST_QUERYHannes Reinecke
Newer firmware implement a LD_LIST_QUERY command, and due to a driver issue no drives might be detected if this command isn't supported. So add emulation for this command, too.
