2011-10-28scsi-generic: drop SCSIGenericStatePaolo Bonzini1-50/+40
It is not needed, because s->bs is already stored in SCSIDevice, and can be reached from the conf.bs member. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-10-28scsi-disk: fix retrying a flushPaolo Bonzini1-6/+3
Flush does not go anymore through scsi_disk_emulate_command. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-10-28scsi-disk: fail READ CAPACITY if LBA != 0 but PMI == 0Paolo Bonzini1-0/+6
Tested by the Windows Logo Kit SCSI Compliance test. From SBC-3, paragraph 5.25: "The LOGICAL BLOCK ADDRESS field shall be set to zero if the PMI bit is set to zero. If the PMI bit is set to zero and the LOGICAL BLOCK ADDRESS field is not set to zero, then the device server shall 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".

2011-10-28scsi: add channel to addressingPaolo Bonzini5-21/+25
This also requires little more than adding the new argument to scsi_device_find, and the qdev property. All devices by default end up on channel 0. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-10-28scsi: allow arbitrary LUNsPaolo Bonzini6-24/+75
This only requires changes in two places: in SCSIBus, we need to look for a free LUN if somebody creates a device with a pre-existing scsi-id but the default LUN (-1, meaning "search for a free spot"); in vSCSI, we need to actually parse the LUN according to the SCSI spec. For vSCSI, max_target/max_lun are set according to the logical unit addressing format in SAM. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-10-28scsi: remove devs array from SCSIBusPaolo Bonzini6-52/+50
Change the devs array into a linked list, and add a scsi_device_find function to navigate the children list instead. This lets the SCSI bus use more complex addressing, and HBAs can talk to the correct device when there are multiple LUNs per target. scsi_device_find may return another LUN on the same target if none is found that matches exactly.

2011-10-28qdev: switch children device list to QTAILQPaolo Bonzini8-28/+28
SCSI buses will need to read the children list first-to-last. This requires using a QTAILQ, because hell breaks loose if you just try inserting at the tail (thus reversing the order of all existing visits from last-to-first to first-to-tail).

2011-10-28scsi-disk: report media changed via GET EVENT STATUS NOTIFICATIONPaolo Bonzini1-4/+53

2011-10-28atapi/scsi-disk: make mode page values coherent between the twoPaolo Bonzini2-16/+31
This patch adds to scsi-disk the missing mode page 0x01 for both disk and CD-ROM drives, and mode page 0x0e for CD drives only. A few offsets were wrong in atapi.c. Also change the 2Ah mode page to expose DVD media read capabilities in the IDE cdrom. This lets you run dvd+rw-mediainfo on the virtual DVD drives.

2011-10-28scsi-disk: store valid mode pages in a tablePaolo Bonzini1-12/+13

2011-10-28scsi-disk: add stubs for more MMC commandsPaolo Bonzini2-5/+65
This patch adds a few stub implementations for MMC commands to scsi-disk, to be filled in later in the series. It also adds to scsi-defs.h constants for commands implemented by ide/atapi.c, when missing. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-10-28scsi-disk: report media changed via unit attention sense codesPaolo Bonzini3-1/+35
Building on the previous patch, this one adds a media change callback to scsi-disk. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-10-28scsi: notify the device when unit attention is reportedPaolo Bonzini2-5/+29
Reporting media change events via unit attention sense codes requires a small state machine: first report "NO MEDIUM", then report "MEDIUM MAY HAVE CHANGED". Unfortunately there is no good hooking point for the device to notice that its pending unit attention condition has been reported. This patch reworks the generic machinery to add one.

2011-10-28atapi: cleanup/fix mode sense resultsPaolo Bonzini1-4/+6
The first two bytes (after the 8-byte ATAPI header) are the mode page number and the number of bytes after the length field itself. Make this clear in the code. The AUDIO_CTL page was filled with wrong values. It is not anymore in MMC, but at least keep the values sane.

2011-10-28atapi: move GESN definitions to scsi-defs.hPaolo Bonzini2-37/+27
As a complement to the previous patch, move definitions for GET EVENT STATUS NOTIFICATION from the two functions to scsi-defs.h. The NCR_* constants are just bit values corresponding to the ENC_* values, with no offsets even, so keep just one copy. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-10-28atapi/scsi: unify definitions for MMCPaolo Bonzini7-104/+101
The definitions in ide/internal.h are duplicates, since ATAPI commands actually come from SCSI. Use the ones in scsi-defs.h and move the missing ones there. Two exceptions: - MODE_PAGE_WRITE_PARMS conflicts with the "flexible disk geometry" page in scsi-disk.c. It is unused, so pick the latter. - GPCMD_* is left in ide/internal.h, at least for now.

Fix incorrect order of arguments, letting writes to NVRAM succeed. It looks like guests never write to the device, only read from it, since the bug originates back to 819385c58b319d9f80d676cefaed0610118f03ac. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-10-21pc: Fix floppy drives with if=noneKevin Wolf5-16/+38
Commit 63ffb564 broke floppy devices specified on the command line like -drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it relies on drive_get() which works only with -fda/-drive if=floppy. This patch resembles what we're already doing for IDE, i.e. remember the floppy device that was created and use that to extract the BlockDriverStates where needed.

2011-10-21fdc: Fix floppy port I/OKevin Wolf1-0/+2
The floppy device was broken by commit 212ec7ba (fdc: Convert to isa_register_portio_list). While the old interface provided the port number relative to the floppy drive's io_base, the new one provides the real port number, so we need to apply a bitmask now to get the register number.
