2012-08-01fix Xen compilationStefano Stabellini1-3/+1
xen_pt_unregister_device is used as PCIUnregisterFunc, so it should match the type. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-08-01net: Rename qemu_del_vlan_client() to qemu_del_net_client()Stefan Hajnoczi8-8/+8
Another step in moving the vlan feature out of net core. Users only deal with NetClientState and therefore qemu_del_vlan_client() should be named qemu_del_net_client().

2012-08-01net: Rename vc local variables to ncStefan Hajnoczi2-11/+11
Now that VLANClientState has been renamed to NetClientState all 'vc' local variables should be 'nc'. Much of the code already used 'nc' but there are places where 'vc' needs to be renamed.

2012-08-01net: Rename VLANClientState to NetClientStateStefan Hajnoczi32-98/+98
The vlan feature is no longer part of net core. Rename VLANClientState to NetClientState because net clients are not explicitly associated with a vlan at all, instead they have a peer net client to which they are connected. This patch is a mechanical search-and-replace except for a few whitespace fixups where changing VLANClientState to NetClientState misaligned whitespace.

The vlan implementation in net.c has been replaced by hubs so we can remove the code. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Zhi Yong Wu <wuzhy@linux.vnet.ibm.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com>
2012-08-01net: Convert qdev_prop_vlan to peer with hubZhi Yong Wu2-16/+27
Instead of using VLANState use net/hub.h to support the vlan qdev property. The vlan qdev property becomes an alias for the peer qdev property but is represented as a VLAN ID number. When a VLAN ID is selected the device will really peer with a hub port.

2012-07-27virtio-scsi: enable MSI-X supportPaolo Bonzini1-2/+4
While virtio-scsi does support multiqueue, the default number of interrupt vectors is not enough to actually enable usage of multiple queues in the driver; this is because with only 2 vectors the driver will not be able to use a separate interrupt for each request queue. Derive the desired number of vectors from the number of request queues. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-27virtio-scsi: add ioeventfd supportPaolo Bonzini1-0/+1
Probably due to bad merge months ago, virtio-scsi-pci did not have ioeventfd support. Fix this and enable it by default, as is the case for other virtio-pci devices. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-07-27scsi: establish precedence levels for unit attentionPaolo Bonzini3-3/+54
When a device is resized, we will report a unit attention condition for CAPACITY DATA HAS CHANGED. However, we should ensure that this condition does not override a more important unit attention condition. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-27scsi: introduce hotplug() and hot_unplug() interfaces for SCSI busCong Meng2-1/+18
Add two interfaces hotplug() and hot_unplug() to scsi bus info. The scsi bus can implement these two interfaces to signal the HBA driver of guest kernel to add/remove the scsi device in question.

2012-07-27scsi-disk: removable hard disks support load/ejectPaolo Bonzini1-1/+1
Support for the LOEJ bit of the START/STOP UNIT command right now is limited to CD-ROMs. This is wrong, since removable hard disks (in the real world: SD card readers) also support it in pretty much the same way. Without the LOEJ bit, START/STOP UNIT does nothing for all devices. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: Fail medium writes with proper sense for readonly LUNsRonnie Sahlberg3-3/+19

2012-07-26scsi-disk: improve the lba-out-of-range tests for read/write/verifyRonnie Sahlberg1-2/+4
Improve the tests for the LBA to cover more cases. For the 16 byte opcodes, the lba is a uint64, so we need to check is to make sure that we do not wrap. For example if an opcode would specify the LBA:0xffffffffffffffff and LEN:2 then lba+len would wrap to 1. Also verify that ALL requested blocks are available, not just the first one.

2012-07-26scsi-disk: rd/wr/vr-protect !=0 is an errorRonnie Sahlberg1-0/+9
The QEMU SCSI emulation does not support protection information, so any READ/WRITE/VERIFY commands that has the protect bits set to non-zero should fail with ILLEGAL_REQUEST/INVALID_FIELD_IN_CDB From SCSI SBC : If the logical unit does not support protection information, then the device server should terminate the command with CHECK CONDITION status with the sense key set to ILLEGAL REQUEST and the additional sense code set to INVALID FIELD IN CDB.

2012-07-26scsi-disk: support toggling the write cachePaolo Bonzini1-4/+10
Finally, this uses the "plumbing" in the previous patch to add support for toggling the WCE bit of the caching mode page. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: parse MODE SELECT commands and parametersPaolo Bonzini3-11/+169
This adds the bulk of the parsing code for MODE SELECT, including breaking out changes to different mode pages, and checking that only changeable values are modified. In order to report errors correctly two passes are made through the parameters; the first only looks for errors, the second actually applies the changes to the mode page. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: fix changeable values for MODE_PAGE_R_W_ERRORPaolo Bonzini1-0/+3
The changeable values were not all-zeros for this mode page, fix it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: adjust offsets in MODE SENSE by 2Paolo Bonzini1-66/+74
This will make offsets the same when implementing MODE SELECT. This is because MODE SELECT has to deal with both 2-byte and 4-byte headers. Unfortunately, this means that the offsets are now off by two compared to the descriptions in the SCSI specs, which include the header. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: support emulated TO_DEV requestsPaolo Bonzini1-8/+28
This adds the implementation of write_data for the emulated command case. The first time through it asks for more data, the second time it finishes the processing of the command. MODE SELECT and MODE SELECT(10) can now be re-enabled, but they will not do much. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: separate read_data/write_data implementation for emulate_reqopsPaolo Bonzini1-11/+25
The previous patch only separated the send_command callback. Use different implementations also for read_data and write_data. The latter is still unreachable, so it aborts for now. read_data passes the data buffer that was prepared and completes the command. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: split scsi-disk reqopsPaolo Bonzini1-68/+123
Only checks for present medium were still done in scsi_send_command for emulated commands. So move those to scsi_disk_emulate_command and return different SCSIReqOps depending on the kind of command. Checks for present medium can be done unconditionally for the scsi_disk_dma_reqops case. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: move all non-DMA commands to scsi_disk_emulate_commandPaolo Bonzini1-86/+66
We want to use separate SCSIReqOps for emulated commands needing an allocated buffer vs. those that are zerocopy when the HBA supports S/G lists. Ensure that all of the former are in scsi_disk_emulate_command. Commands that do not have any parameters are more similar to emulated commands, so also move them, even if they do I/O. Finally, MODE SELECT and MODE SELECT(10) are broken because we do not yet support passing parameter data _to_ emulated commands, so disable them. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: make discard asynchronousPaolo Bonzini1-12/+10
By making discard asynchronous, we can reuse all the error handling code that is used for other commands. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26scsi-disk: let the user customize vendor and product nameDmitry Fleytman1-10/+21

2012-07-26scsi-block: remove properties that are not relevant for passthroughPaolo Bonzini1-1/+1
scsi-block is a passthrough device and does not allow customization of vendor, product, removable, DPOFUA, block size or any other piece of information. Thus, drop DEFINE_SCSI_DISK_PROPERTIES() from the list of qdev properties. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26lsi: avoid redundant tests of s->current != NULLPaolo Bonzini1-2/+3
Simplify the code by checking against req->hba_private directly, and asserting that it is non-NULL before a command is completed or canceled. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26lsi: introduce lsi_request_freePaolo Bonzini1-15/+16
Split the common bits of lsi_request_cancelled and lsi_command_complete out to a new function. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26lsi: use qdev_reset_allPaolo Bonzini1-12/+3
By first resetting the devices, lsi_soft_reset will find the queue already cleared so there is no need to do that forcibly (which may also leak SCSIRequests, and/or worse due to dangling references to the lsi_request in the hba_private field). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26megasas: fix misuse of scsi_req_abortPaolo Bonzini1-1/+1
scsi_req_abort is for terminating a command with a non-zero status. The ABORT task management function is invoked by scsi_req_cancel. In fact, ABORTED_COMMAND is a sense key, not a SAM status code. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-07-26megasas: Replace trace_megasas_dcmd_dump_frame()Hannes Reinecke1-29/+10
trace_megasas_dcmd_dump_frame() takes 9 arguments, which is rather much. Plus the trace infrastructure doesn't support it. As we can get the information via other means it's pointless to have it in the driver, so rather use some proper trace point here and remove the old one.
