2012-07-09fdc: Drop broken code for user-defined floppy geometryMarkus Armbruster1-3/+0
bdrv_get_floppy_geometry_hint() fails to store through its parameter drive when bs has a geometry hint. Makes fd_revalidate() assign random crap to drv->drive. Has been broken that way for ages. Harmless, because: * The only way to set a geometry hint is -drive if=none,cyls=... Since commit c219331e, probably unintentional. * The only use of drv->drive is as argument to another bdrv_get_floppy_geometry_hint(). Which doesn't use it, since the geometry hint is still there. Drop the broken code, ignore -drive parameter cyls, heads and secs for floppies even with if=none, just like before commit c219331e. Matches -help, which explains cyls, heads, secs as "hard disk physical geometry". Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-07-09ehci: Kick async schedule on wakeup in the non companion caseHans de Goede1-2/+3
Commit 0f588df8b3688b00e77aabaa32e26ece5f19bd39, added code to ehci_wakeup to kick the async schedule on wakeup, but the else was positioned wrong making it trigger for devices which are routed to the companion rather then to the ehci controller itself. This patch fixes this. Note that the "programming style" with using the return at the end of the companion block matches how the companion case is handled in the other ports ops, and is done this way for consistency.

2012-07-09ehci: don't flush cache on doorbell rings.Gerd Hoffmann1-6/+29
Commit 4be23939ab0d7019c7e59a37485b416fbbf0f073 makes ehci instantly zap any unlinked queue heads when the guest rings the doorbell. While hacking up uas support this turned out to be a problem. The linux kernel can unlink and instantly relink the very same queue head, thereby killing any async packets in flight. That alone isn't an issue yet, the packet will canceled and resubmitted and everything is fine. We'll run into trouble though in case the async packet is completed already, so we can't cancel it any more. The transaction is simply lost then. usb_ehci_qh_ptrs q (nil) - QH @ 39c4f000: next 39c4f122 qtds 00000000,00000001,39c50000 usb_ehci_qh_fields QH @ 39c4f000 - rl 0, mplen 0, eps 0, ep 0, dev 0 usb_ehci_qh_ptrs q 0x7f95feba90a0 - QH @ 39c4f000: next 39c4f122 qtds 00000000,00000001,39c50000 usb_ehci_qh_fields QH @ 39c4f000 - rl 0, mplen 0, eps 0, ep 0, dev 0 usb_ehci_qh_ptrs q 0x7f95fe515210 - QH @ 39c4f120: next 39c4f0c2 qtds 29dbce40,29dbc4e0,00000009 usb_ehci_qh_fields QH @ 39c4f120 - rl 4, mplen 512, eps 2, ep 1, dev 2 usb_ehci_packet_action q 0x7f95fe515210 p 0x7f95fdec32a0: alloc usb_packet_state_change bus 0, port 2, ep 1, packet 0x7f95fdec32e0, state undef -> setup usb_ehci_packet_action q 0x7f95fe515210 p 0x7f95fdec32a0: process usb_uas_command dev 2, tag 0x2, lun 0, lun64 00000000-00000000 scsi_req_parsed target 0 lun 0 tag 2 command 42 dir 2 length 16384 scsi_req_parsed_lba target 0 lun 0 tag 2 command 42 lba 5933312 scsi_req_alloc target 0 lun 0 tag 2 scsi_req_continue target 0 lun 0 tag 2 scsi_req_data target 0 lun 0 tag 2 len 16384 usb_uas_scsi_data dev 2, tag 0x2, bytes 16384 usb_uas_write_ready dev 2, tag 0x2 usb_packet_state_change bus 0, port 2, ep 1, packet 0x7f95fdec32e0, state setup -> complete usb_ehci_packet_action q 0x7f95fe515210 p 0x7f95fdec32a0: free usb_ehci_qh_ptrs q 0x7f95fdec3210 - QH @ 39c4f0c0: next 39c4f002 qtds 29dbce40,00000001,00000009 usb_ehci_qh_fields QH @ 39c4f0c0 - rl 4, mplen 512, eps 2, ep 2, dev 2 usb_ehci_queue_action q 0x7f95fe5152a0: free usb_packet_state_change bus 0, port 2, ep 2, packet 0x7f95feba9170, state async -> complete ^^^ async packets completes. usb_ehci_packet_action q 0x7f95fdec3210 p 0x7f95feba9130: wakeup usb_ehci_qh_ptrs q (nil) - QH @ 39c4f000: next 39c4f122 qtds 00000000,00000001,39c50000 usb_ehci_qh_fields QH @ 39c4f000 - rl 0, mplen 0, eps 0, ep 0, dev 0 usb_ehci_qh_ptrs q 0x7f95feba90a0 - QH @ 39c4f000: next 39c4f122 qtds 00000000,00000001,39c50000 usb_ehci_qh_fields QH @ 39c4f000 - rl 0, mplen 0, eps 0, ep 0, dev 0 usb_ehci_qh_ptrs q 0x7f95fe515210 - QH @ 39c4f120: next 39c4f002 qtds 29dbc4e0,29dbc8a0,00000009 usb_ehci_qh_fields QH @ 39c4f120 - rl 4, mplen 512, eps 2, ep 1, dev 2 usb_ehci_queue_action q 0x7f95fdec3210: free usb_ehci_packet_action q 0x7f95fdec3210 p 0x7f95feba9130: free ^^^ endpoint #2 queue head removed from schedule, doorbell makes ehci zap the queue, the (completed) usb packet is freed too and gets lost. usb_ehci_qh_ptrs q (nil) - QH @ 39c4f000: next 39c4f0c2 qtds 00000000,00000001,39c50000 usb_ehci_qh_fields QH @ 39c4f000 - rl 0, mplen 0, eps 0, ep 0, dev 0 usb_ehci_qh_ptrs q 0x7f95feba90a0 - QH @ 39c4f000: next 39c4f0c2 qtds 00000000,00000001,39c50000 usb_ehci_qh_fields QH @ 39c4f000 - rl 0, mplen 0, eps 0, ep 0, dev 0 usb_ehci_queue_action q 0x7f9600dff570: alloc usb_ehci_qh_ptrs q 0x7f9600dff570 - QH @ 39c4f0c0: next 39c4f122 qtds 29dbce40,00000001,00000009 usb_ehci_qh_fields QH @ 39c4f0c0 - rl 4, mplen 512, eps 2, ep 2, dev 2 usb_ehci_packet_action q 0x7f9600dff570 p 0x7f95feba9130: alloc usb_packet_state_change bus 0, port 2, ep 2, packet 0x7f95feba9170, state undef -> setup usb_ehci_packet_action q 0x7f9600dff570 p 0x7f95feba9130: process usb_packet_state_change bus 0, port 2, ep 2, packet 0x7f95feba9170, state setup -> async usb_ehci_packet_action q 0x7f9600dff570 p 0x7f95feba9130: async ^^^ linux kernel relinked the queue head, ehci creates a new usb packet, but we should have delivered the completed one instead. usb_ehci_qh_ptrs q 0x7f95fe515210 - QH @ 39c4f120: next 39c4f002 qtds 29dbc4e0,29dbc8a0,00000009 usb_ehci_qh_fields QH @ 39c4f120 - rl 4, mplen 512, eps 2, ep 1, dev 2 So instead of instantly zapping the queue we'll set a flag that the queue needs revalidation in case we'll see it again in the schedule. ehci then checks that the queue head fields addressing / describing the endpoint and the qtd pointer match the cached content before reusing it.

2012-07-02ISCSI: Add SCSI passthrough via scsi-generic to libiscsiRonnie Sahlberg1-8/+5
Update iscsi to allow passthrough of SG_IO scsi commands when the iscsi device is forced to be scsi-generic. Implement both bdrv_ioctl() and bdrv_aio_ioctl() in the iscsi backend, emulate the SG_IO ioctl and pass the SCSI commands across to the iscsi target. This allows end-to-end passthrough of SCSI all the way from the guest, to qemu, via scsi-generic, then libiscsi all the way to the iscsi target. To activate this you need to specify that the iscsi lun should be treated as a scsi-generic device. Example: -device lsi -device scsi-generic,drive=MyISCSI \ -drive file=iscsi://10.1.1.125/iqn.ronnie.test/1,if=none,id=MyISCSI Note, you can currently not boot a qemu guest from a scsi device. Note, This only works when the host is linux, since the emulation relies on definitions of SG_IO from the scsi-generic implementation in the linux kernel. It should be fairly easy to re-implement some structures similar enough for non-linux hosts to do the same style of passthrough via a fake scsi generic layer and libiscsi if need be.
