2012-06-08qdev: Remove PropertyInfo range checkingPaolo Bonzini
Range checking in PropertyInfo is now used only for pci_devfn properties and some error reporting. Remove all code that implements it in the various property types, and the now unused fields. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> [AF: Fix blocksize min/max for 32-bit hosts by using const int64_t.] Signed-off-by: Andreas Färber <afaerber@suse.de>
2012-06-08qdev: Switch property accessors to fixed-width visitor interfacesMichael Roth
This introduces {get,set}_uint{8,16,32,64}() functions for the respective qdev types. TADDR and VLAN are switched to explicit int64, BLOCKSIZE to uint16.

2012-06-08qdev: Use int32_t container for devfn propertyMichael Roth
Valid range for devfn is -1 to 255 (-1 for automatic assignment). We do not currently validate this due to devfn being stored as a uint32_t. This can lead to segfaults and other strange behavior. We could technically just cast it to int32_t to implement the checking, but this will not work for visitor-based setting where we may do additional bounds-checking based on target container type, which is int32_t for this case.

2012-06-08qapi: Add Visitor interfaces for uint*_t and int*_tMichael Roth
This adds visitor interfaces for fixed-width integers types. Implementing these in visitors is optional, otherwise we fall back to visit_type_int() (int64_t) with some additional bounds checking to avoid integer overflows for cases where the value fetched exceeds the bounds of our target C type.

2012-06-07ehci: rework frame skippingGerd Hoffmann
Move the framecount check out of the loop and use the new ehci_update_frindex function to skip frames if needed. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: adaptive wakeup rate.Gerd Hoffmann
Adapt the frame timer sleeps according to the actual needs. With the periodic schedule being active we'll have to wakeup 1000 times per second and go check for work. In case only the async schedule is active we can be more lazy though. When idle ehci will increate the sleep time step by step, so qemu has to wake up less frequently. When we'll see transactions on the bus or the guest fiddles with the schedule enable/disable bits we'll return to a 1000 Hz wakeup rate and full speed. With both schedules disabled we stop wakeups altogether. This patch also drops the freq property (configures wakeup rate manually) which is obsoleted by this patch.

2012-06-07ehci: create ehci_update_frindexGerd Hoffmann
Factor out code from ehci_frame_timer. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: remove unused attach_poll_counterGerd Hoffmann
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: fix halt status handlingGerd Hoffmann
When the enable bits for controller / async schedule / periodic schedule change just make sure we kick the frame timer and let ehci_advance_periodic_state and ehci_advance_async_state handle the controller state changes. This will make ehci set USBSTS_HALT when the controller shutdown is actually done, once both schedules are in inactive state and the USBSTS_PSS and USBSTS_ASS bits are clear. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: update status bits in ehci_set_stateGerd Hoffmann
Update the status register in the ehci_set_state function, to make sure the guest-visible register is in sync with our internal schedule state. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: add ehci_*_enabled() helpersGerd Hoffmann
Add helper functions to query whenever the async / periodic schedule is enabled or not. Put them into use too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: fix resetGerd Hoffmann
Check for the reset bit first when processing USBCMD register writes. Also break out of the switch, there is no need to check the other bits. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: kick async schedule on wakeupGerd Hoffmann
Kick async schedule when we get a wakeup notification from a usb device. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: schedule async bh on async packet completionGerd Hoffmann
When a packet completes which happens to be part of the async schedule kick the async bottom half for processing, Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: move async schedule to bottom halfGerd Hoffmann
This way we can kick the async schedule independant from the periodic frame timer. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: add async field to EHCIQueueGerd Hoffmann
Keep track whenever a EHCIQueue is part of the async or periodic schedule. This way we don't have to pass around the async flag everywhere but can look it up from the EHCIQueue struct when needed. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: tweak queue initializationGerd Hoffmann
Little tweak for the queue initialization, set the QH address in the allocation function. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: add queuing supportGerd Hoffmann
Add packet queuing. Follow the qTD chain to see if there are more packets we can submit. Improves performance on larger transfers, especially with usb-host, as we don't have to wait for a packet to finish before sending the next one to the host for processing. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: move ehci_flush_qhGerd Hoffmann
Move ehci_flush_qh() function up in the source code. No code change. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: cache USBDevice in EHCIQueueGerd Hoffmann
Keep a USBDevice pointer in EHCIQueue so we don't have to lookup the device on each usb packet submission. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: make ehci_execute work on EHCIPacket instead of EHCIQueueGerd Hoffmann
This way it is possible to use ehci_execute to submit others than the first EHCIPacket of the EHCIQueue. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07ehci: add EHCIPacketGerd Hoffmann
Add a separate EHCIPacket struct and move fields over from EHCIQueue. Preparing for supporting multiple packets per queue being in flight at the same time. No functional changes yet. Fix some codestyle issues along the way. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-06-07usb-storage: migration supportGerd Hoffmann
With all scsi migration support bits in place the final step is pretty simple ;) Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07usb-storage: add scsi_off, remove scsi_bufGerd Hoffmann
Repace the running buffer pointer (scsi_buf) with a buffer offset field (scsi_off). The later is alot easier to live-migrate. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07usb-storage: add usb_msd_packet_complete()Gerd Hoffmann
Factor out packet completion to a separate function which cares to get the MSDState->packet update right. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07usb-storage: remove MSDState->residueGerd Hoffmann
We have the field twice, once in MSDState directly and one in the status word struct. Drop one. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07scsi: prepare migration code for usb-storage supportGerd Hoffmann
usb-storage can't handle requests in one go as the data transfer can be splitted into lots of usb packets. Because of that there can be normal in-flight requests at savevm time and we need to handle that. With other scsi hba's this happens only in case i/o is stopped due to errors and there are pending requests which need to be restarted (req->retry = true). So, first we need to save req->retry and then handle the req->retry = false case. Write requests are handled fine already. For read requests we have to save the buffer as we will not restart the request (and thus not refill the buffer) on the target host.

2012-06-07uhci: fix irq routingGerd Hoffmann
The multifunction ich9 ehci controller with uhci companions uses a different interrupt pin for each function. The three uhci devices get pins A, B and C, whereas ehci uses pin D. This way the guest can assign different IRQ lines to each controller. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07uhci: zap uhci_pre_saveGerd Hoffmann
Cancel transactions before saving vmstate is pretty pointless and just causes disruptions. We need to cancel them before *loading* vmstate, but in that case uhci_reset() handles it already and no special action is needed. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07uhci: make bandwidth tunableGerd Hoffmann
Add a property for the uhci bandwidth. Can be used to make uhci emulation run faster than real hardware. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07uhci: use bottom halfGerd Hoffmann
Schedule bottom half on completion of async packets instead of calling uhci_process_frame directly. This way we run uhci_process_frame only once in case multiple packets finish in a row. Also check whenever there is bandwidth left before scheduling uhci_process_frame. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-07uhci: fix bandwidth managementGerd Hoffmann
uhci_process_frame() can be invoked multiple times per frame, so accounting usb bandwith in a local variable doesn't fly, use a variable in UHCIState instead. Also check the limit more frequently. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-06-07build: move per-target hw/ objects to nested Makefile.objsPaolo Bonzini
This completes the move to nested Makefiles for virtio and a few other files that were not part of obj-TARGET-y, but still were compiled separately for each target. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-06-07build: convert libhw to nested Makefile.objsPaolo Bonzini
After this patch, the libhw* directories will have a hierarchy that mimics the source tree. This is useful because we do have a couple of files there that are in the top source directory. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-06-07build: move target-independent hw/ objects to nested Makefile.objsPaolo Bonzini
This patch starts converting the hw/ directory. Some files in hw/ are compiled once, some twice (32-/64-bit), some once per target. Each category is moved in a separate patch. After this patch, the files that are compiled once will show the same hierarchy in the build tree as they do in the source tree, for example hw/qdev.o instead of just qdev.o.
