2011-06-15hw/9118.c: Implement active-low interrupt supportPeter Maydell1-3/+9
The 9118 ethernet controller interrupt line is active low unless the IRQ config register is programmed to set both the IRQ_POL (polarity: active-high) and IRQ_TYPE (type: push-pull) bits: implement support for inverting the irq output in other configurations. This also requires that we support setting the bits in the first place, and that we correctly preserve them across software reset.

2011-06-15ide: Clear error_status after restarting flushKevin Wolf1-7/+11
Clearing the error status flag was missing for restarting flushes. Now that the error status is separate from the BM status register, we can simply set it to 0 after restarting the request. This ensures that we never forget to clear a bit. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-06-15ide: Fix ide_drive_pio_state_needed()Kevin Wolf1-1/+2
When a failed PIO request caused the VM to stop, we still need to transfer the PIO state even though DRQ=0 at this point. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-06-15ide: Split error status from status registerKevin Wolf4-8/+105
When adding the werror=stop mode, some flags were added to s->status which are used to determine what kind of operation should be restarted when the VM is continued. Unfortunately, it turns out that s->status is in fact a device register and as such is visible to the guest (some of the abused bits are even writable for the guest). For migration we keep on using the old VMState field (renamed to migration_compat_status) if the status register doesn't use any of the previously abused bits. If it does, we use a subsection with a clean copy of the status register. The error status is always sent in a subsection if there is any error. It can't use the old field because errors happen even without PCI. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

HcPeriodCurrentED is read-only, but Linux writes to it anyway; silently ignore this rather than printing a warning message. (Specifically, drivers/usb/host/ohci-hub.c:ohci_rh_resume() writes a 0, in at least kernels 2.6.25 through 2.6.39.)

2011-06-14usb-ehci: itd handling fixes.Gerd Hoffmann1-36/+65
This patch fixes a bunch of issues in the itd descriptor handling. Most important fix is to handle transfers which cross page borders correctly by looking up the address of the next page. Luckily the linux uses physically contigous memory so the data used to hits the correct location even with this bug instead of corrupting guest memory. Also the transfer length updates for outgoing transfers wasn't correct. While being at it DPRINTFs have been replaced by tracepoints. The isoch_pause logic has been disabled. Not clear to me which propose this serves and I think it is incorrect too as we just skip processing itds. Even when no xfer happens we have to clear the active bit.

2011-06-14The USB tablet should not claim boot protocol support.Kevin O'Connor1-1/+0

2011-06-14Fix USB mouse Set_Protocol behaviorKevin O'Connor1-2/+2
The QEMU USB mouse claims to support the "boot" protocol (bInterfaceSubClass is 1). However, the mouse rejects the Set_Protocol command. The qemu mouse does support the "boot" protocol specification, so a simple fix is to enable the Set_Protocol request.

2011-06-14usb-ehci: drop EXECUTING checks.Gerd Hoffmann1-30/+2
The state machine doesn't stop in EXECUTING state any more when async packets are in flight, so the checks are not needed any more and can be dropped. Also kick out the check for the frame timer. As we don't stop & sleep any more on async packets this is obsolete. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb: cancel async packets on unplugGerd Hoffmann7-7/+106
This patch adds USBBusOps struct with (for now) only a single callback which is called when a device is about to be destroyed. The USB Host adapters are implementing this callback and use it to cancel any async requests which might be in flight before the device actually goes away.

2011-06-14usb-ehci: fix offset writeback in ehci_buffer_rwGerd Hoffmann1-2/+2
Two bugs at once: First the mask is backwards, so the it used to keeps the offset and clears the page address, which is not what we need when we update the offset. Second the offset calculation is wrong in case head isn't page aligned. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: multiqueue supportGerd Hoffmann1-32/+139
This patch adds support for keeping multiple queues going at the same time. One slow device will not affect other devices any more. The patch adds code to manage EHCIQueue structs. It also does a number of changes to the state machine: * The state machine will never ever stop in EXECUTING any more. Instead it will continue with the next queue (aka HORIZONTALQH) when the usb device returns USB_RET_ASYNC. * The state machine will stop processing when it figures it walks in circles (easy to figure now that we have a EHCIQueue struct for each QH we've processed). The bailout logic should not be needed any more. For now it is still in, but will assert() in case it triggers. * The state machine will just skip queues with a async USBPacket in flight. * The state machine will resume processing as soon as the async USBPacket is finished. The patch also takes care to flush the QH struct back to guest memory when needed, so we don't get stale data when (re-)loading it from guest memory in FETCHQH state. It also makes the writeback code to not touch the first three dwords of the QH struct as the EHCI must not write them. This actually fixes a bug where QH chaining changes (next ptr) by the linux ehci driver where overwritten by the emulated EHCI. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: add queue data structGerd Hoffmann1-229/+257
Add EHCIQueue struct, move the fields needed to track the queue state into that struct. Pass the new struct instead of ehci state down to functions which handle the queue state. Lot of variable references have changed due to that without an actual functional change. Replace fetch_addr with two variables, one for async and one for periodic schedule. Add functions to get and set the fetch address. Use EHCIQueue->usb_status (old name: EHCIState->exec_status) directly in ehci_execute_complete instead of passing around the status using a parameters and the return value. ehci_state_fetchqh returns a EHCIQueue struct now. No change in behavior. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-06-14usb-ehci: trace state machine changesGerd Hoffmann1-137/+170
Add functions to get and set the current state of the state machine, add tracepoints there to trace state transitions.

2011-06-08ide/core: Remove explicit setting of BM_STATUS_INTKevin Wolf1-3/+4
BM_STATUS_INT is automatically set during ide_set_irq(), there's no reason to set it manually in addition. There is even one case where the interrupt status bit was set, but no IRQ was raised. This is when the PRD table was reached but there is more data to transfer. The correct behaviour for this case is not to set BM_STATUS_INT. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

Commit 353ac78d495ef976242abd868f68d78420861c2c moved the files without fixing the include paths. It used a modified CFLAGS to add hw to the include search path, but this breaks builds where the user wants to set special CFLAGS. Long include paths also increase compilation time.
