2012-02-17ARM: exynos4210: basic Power Management Unit implementationMaksim Kozlov2-0/+508
Patch adds basic model for Exynos4210 SoC PMU. This model implements PMU registers just as a bulk of memory. Currently, the only reason this device exists is that secondary CPU boot loader uses PMU INFORM5 register as a holding pen.

2012-02-14qdev: print error message before abortingPaolo Bonzini1-13/+13
qdev_prop_set_* functions are always called by machine init functions that should know what they're doing, so they abort on error. Still, an assert(!errp) does not aid debugging.

2012-02-10xhci: handle USB_RET_NAKGerd Hoffmann1-11/+96
Add a field to XHCITransfer to correctly keep track of NAK'ed usb packets. Retry transfers when the endpoint is kicked again. Implement wakeup_endpoint bus op so we can kick the endpoint when needed. With this patch applied the emulated hid devices are working correctly when hooked up to xhci. usb-tabled without polling, yay! Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-10usb: add USBBusOps->wakeup_endpointGerd Hoffmann2-0/+5
Add usb bus op which is called whenever a usb endpoint becomes ready, so the host adapter emulation can react on that event. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: pass USBEndpoint to usb_wakeupGerd Hoffmann5-7/+15
Devices must specify which endpoint has data to transfer now. The plan is to use the usb_wakeup() not only for remove wakeup support, but for "data ready" signaling in general, so we can move away from constant polling to event driven usb device emulation. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: maintain async packet list per endpointGerd Hoffmann2-28/+108
Maintain a list of async packets per endpoint. With the current code the list will never receive more than a single item. I think you can guess what the future plan is though ;) Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: Set USBEndpoint in usb_packet_setup().Gerd Hoffmann16-62/+67
With the separation of the device lookup (via usb_find_device) and packet processing we can lookup device and endpoint before setting up the usb packet. So we can initialize USBPacket->ep early and keep it valid for the whole lifecycle of the USBPacket. Also the devaddr and devep fields are not needed any more. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: add USBEndpoint->{nr,pid}Gerd Hoffmann2-0/+7
Add a "nr" and "pid" fields to USBEndpoint so you can easily figure the endpoint number and direction of any given endpoint. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: USBPacket: add status, rename owner -> epGerd Hoffmann6-18/+35
Add enum to track the status of USBPackets, use that instead of the owner pointer to figure whenever a usb packet is currently in flight or not. Add some more packet status sanity checks. Also rename the USBEndpoint pointer from "owner" to "ep". Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: fold usb_generic_handle_packet into usb_handle_packetGerd Hoffmann1-33/+25
There is no reason to have a separate usb_generic_handle_packet function any more, fold it into usb_handle_packet(). Also call the do_token_* functions which handle control transfer emulation for control pipe packets only. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: kill handle_packet callbackGerd Hoffmann12-80/+4
All drivers except usb-hub use usb_generic_handle_packet. The only reason the usb hub has its own function is that it used to be called with packets which are intended for downstream devices. With the new, separate device lookup step this doesn't happen any more, so the need for a different handle_packet callback is gone. So we can kill the handle_packet callback and just call usb_generic_handle_packet directly. The special hub handling in usb_handle_packet() can go away for the same reason. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb-xhci: switch to usb_find_device()Gerd Hoffmann1-2/+10
Switch over xHCI to use the new usb_find_device() function for device lookup. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb-musb: switch to usb_find_device()Gerd Hoffmann1-4/+3
Switch over musb to use the new usb_find_device() function for device lookup. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-10usb: handle dev == NULL in usb_handle_packet()Gerd Hoffmann1-0/+4
Allow passing in a NULL pointer, return USB_RET_NODEV in that case. Removes the burden to to a NULL pointer check from the callers. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb-hub: implement find_deviceGerd Hoffmann1-0/+21
Implement the find_device callback for the usb hub. It'll loop over all ports, calling usb_find_device for all enabled ports until it finds a matching device. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: add usb_find_device()Gerd Hoffmann3-0/+32
Add usb_find_device(). This function will check whenever a device with a specific address is connected to the specified port. Usually this will just check state and address of the device hooked up to the port, but in case of a hub it will ask the hub to check all hub ports for a matching device. This patch doesn't put the code into use yet, see the following patches for details. The master plan is to separate device lookup and packet processing. Right now the usb code simply walks all devices, calls usb_handle_packet() on each until one accepts the packet (by returning something different that USB_RET_NODEV). I want to have a device lookup first, then call usb_handle_packet() once, for the device which actually processes the packet. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: kill usb_send_msgGerd Hoffmann2-14/+0
No users left. Zap it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: kill USB_MSG_RESETGerd Hoffmann8-31/+25
The USB subsystem pipes internal reset notifications through usb_handle_packet() with a special magic PID. This indirection is a pretty pointless excercise as it ends up being handled by usb_generic_handle_packet anyway. Replace the USB_MSG_RESET with a usb_device_reset() function which can be called directly. Also rename the existing usb_reset() function to usb_port_reset() to avoid confusion. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: kill USB_MSG_{ATTACH,DETACH}Gerd Hoffmann2-13/+3
The USB subsystem pipes internal attach/detach notifications through usb_handle_packet() with a special magic PID. This indirection is a pretty pointless excercise as it ends up being handled by usb_generic_handle_packet anyway. Remove it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb-ehci: Clear the portstatus powner bit on device disconnectHans de Goede1-0/+5
According to the EHCI spec port ownership should revert to the EHCI controller on device disconnect. This fixes the problem of a port getting stuck on USB 1 when using redirection and plugging in a USB 2 device after a USB 1 device has been redirected.

2012-02-10usb-uhci: implement bandwidth managementGerd Hoffmann1-7/+22
The OS is allowed to make the UHCI Controller run in circles. That is usually done to serve multiple connected USB devices in a robin-round fashion, so the available USB bandwidth is evenly distributed between devices. The uhci emulation handles this in a very poor way though. When it figures it runs in circles it stops processing unconditionally, so it usually processes at most a single transfer desriptor per queue, even if there are multiple transfer descriptors are queued up. This patch makes uhci act in a more sophisticated way. It keeps track of successful processed transfer descriptors and transfered bytes. Then it will stop processing when there is nothing to do (no transfer descriptor was completed the last round) or when the transfered data reaches the usb bandwidth limit. Result is that the usb-storage devices connected to uhci are ten times faster, mkfs.vfat time for a 64M stick goes down from five seconds to a half second. Reason for this is that we are now processing up to 20 transfer descriptors (with 64 bytes each) per frame instead of a single one. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-09AHCI: Masking of IRQs actually masks themAlexander Graf1-0/+2
When masking IRQ lines, we should actually mask them out and not declare them active anymore. Once we mask them in again, they are allowed to trigger again. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-02-09AHCI: Fix port reset raceAlexander Graf1-0/+5
bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio that is currently in flight finish. So what we do is: port reset detect ncq in flight cancel ncq delete ncq sg list at which point we have double freed the sg list. Instead, with this patch we do: port reset detect ncq in flight cancel ncq check if we are really still in flight delete ncq sg list which makes things work and gets rid of the race.

2012-02-09ARM devboards: Set arm_sysctl properties before init, not afterPeter Maydell3-3/+3
The ARM devboard models (vexpress-a9, realview, versatilepb, etc) were accidentally trying to set one of the arm_sysctl properties after device init. This has now become a fatal error; set the property before device init where it should be done instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-02-08apic: Fix legacy vmstate loading for KVMJan Kiszka1-1/+6
Also in case of loading pre-vmstate machines, we also need to open-code the reading of the timer expires value and instead call the post_load callback to apply it (or not). This fixes loading of legacy states into the KVM APIC.
