2012-07-12ehci: improve expire time calculationGerd Hoffmann

2012-07-12ehci: raise irq in the frame timerGerd Hoffmann
With the async schedule being kicked from other places than the frame timer (commit 0f588df8b3688b00e77aabaa32e26ece5f19bd39) it may happen that we call ehci_commit_interrupt() more than once per frame. Move the call from the async schedule handler to the frame timer to restore old irq behavior, which is more correct. Fixes regressions with some linux kernel versions. TODO: implement full Interrupt Threshold Control support. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-07-12usb: add usb attached scsi emulationGerd Hoffmann
$subject says all. First cut. It's a pure UAS (usb attached scsi) emulation, without BOT (bulk-only transport) compatibility. If your guest can't handle it use usb-storage instead. The emulation works like any other scsi hba emulation (eps, lsi, virtio, megasas, ...). It provides just the HBA where you can attach scsi devices as you like using '-device'. A single scsi target with up to 256 luns is supported. For now only usb 2.0 transport is supported. This will change in the future though as I plan to use this as playground when codeing up & testing usb 3.0 transport and streams support in the qemu usb core and the xhci emulation. No migration support yet. I'm planning to add usb 3.0 support first as this probably requires saving additional state. Special thanks go to Paolo for bringing the qemu scsi emulation into shape, so this can be added nicely without having to touch a single line of scsi code.

2012-07-12virtio: move common irqfd handling out of virtio-pciPaolo Bonzini
All transports can use the same event handler for the irqfd, though the exact mechanics of the assignment will be specific. Note that there are three states: handled by the kernel, handled in userspace, disabled. This also lets virtio use event_notifier_set_handler.

2012-07-10scsi: add free_request callbackPaolo Bonzini
Most device models have a simple lifecycle for the hba_private field and they can free it when a request is completed or cancelled. However, in some cases it may be simpler to tie the lifetime of hba_private to that of the included SCSIRequest. This patch adds a free_request callback to SCSIBusInfo that lets an HBA device model do exactly that. Normally, device models use req->hba_private == NULL to flag requests that have been completed already. Device models that use free_request will still need to track this using a flag. This is the reason why "converting" existing HBAs to use free_request adds complexity and makes little sense. It is simply an additional convenience that is provided by the SCSI layer. USB-attached storage will be the first user. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-07-10apic: Defer interrupt updates to VCPU threadJan Kiszka
KVM performs TPR raising asynchronously to QEMU, specifically outside QEMU's global lock. When an interrupt is injected into the APIC and TPR is checked to decide if this can be delivered, a stale TPR value may be used, causing spurious interrupts in the end. Fix this by deferring apic_update_irq to the context of the target VCPU. We introduce a new interrupt flag for this, CPU_INTERRUPT_POLL. When it is set, the VCPU calls apic_poll_irq before checking for further pending interrupts. To avoid special-casing KVM, we also implement this logic for TCG mode.

2012-07-10apic: Resolve potential endless loop around apic_update_irqJan Kiszka
Commit d96e173769 refactored the reinjection of pending PIC interrupts. However, it missed the potential loop of apic_update_irq -> apic_deliver_pic_intr -> apic_local_deliver -> apic_set_irq -> apic_update_irq that /could/ occur if LINT0 is injected as APIC_DM_FIXED and that vector is currently blocked via TPR. Resolve this by reinjecting only where it matters: inside apic_get_interrupt. This function may clear a vector while a PIC-originated reason still exists.

2012-07-09fdc: Drop broken code for user-defined floppy geometryMarkus Armbruster
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.

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.

2012-07-09ehci: don't flush cache on doorbell rings.Gerd Hoffmann
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.
