2012-03-14kvmvapic: align start address as well as sizeAvi Kivity1-1/+3
The kvmvapic code remaps a section of ROM as RAM to allow the guest to maintain state there. It is careful to align the section size to a page boundary, to avoid creating subpages, but neglects to do the same for the start address. These leads to an assert later on when the memory core tries to create a page which is half RAM and half ROM. Fix by aligning the start address to a page boundary. This can be triggered by running qemu-system-x86_64 -enable-kvm -vga none. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-03-13kvmclock: Always register typeAndreas Färber1-2/+0
Currently, the "kvmclock" type is only registered when kvm_enabled(). This breaks when moving type registration to before command line parsing (so that QOM types can be used for CPU and machine). Since the QOM classes are lazy-initialized anyway and kvmclock_create() has another kvm_enabled() check, simply drop the KVM check in kvmclock_register_types(). kvm-i8259, kvm-apic and kvm-ioapic do not suffer from such a check.

2012-03-13usb-ohci: DMA writeback bug fixesWei Yang1-2/+15
This patch fixes two bugs in the OHCI device where the device writes back data to system memory that should be exclusively under the control of the guest side driver. In OHCI specification Section 5.2.7, it mentioned "In all cases, Host Controller Driver is responsible for the insertion and removal of all Endpoint Descriptors in the various Host Controller Endpoint Descriptor lists". In the ohci_frame_boundary(), ohci_put_hcca() writes the entire hcca back including the interrupt ED lists which should be under driver control. This violates the specification and can race with a host driver updating that list at the same time. In the OHCI Spec Section 4.6, Transfer Descriptor Queue Processing, it mentioned "Since the TD pointed to by TailP is not accessed by the HC, the Host Controller Driver can initialize that TD and link at least one other to it without creating a coherency or synchronization problem". While the function ohci_put_ed() writes the entire endpoint descriptor back including the TailP which should under driver control. This violate the specification and can race with a host driver updating the TD list at the same time. In each case the solution is to make sure we don't write data which is under driver control.

2012-03-07usb: add shortcut for control transfersGerd Hoffmann2-0/+60
Add a more direct code path to submit control transfers. Instead of feeding three usb packets (setup, data, ack) to usb_handle_packet and have the do_token_* functions in usb.c poke the control transfer parameters out of it just submit a single packet carrying the actual data with the control xfer parameters filled into USBPacket->parameters.

2012-03-07usb: add USB_RET_IOERRORHans de Goede4-5/+11
We already have USB_RET_NAK, but that means that a device does not want to send/receive right now. But with host / network redirection we can actually have a transaction fail due to some io error, rather then ie the device just not having any data atm. This patch adds a new error code named USB_RET_IOERROR for this, and uses it were appropriate. Notes: -Currently all usb-controllers handle this the same as NODEV, but that may change in the future, OHCI could indicate a CRC error instead for example. -This patch does not touch hw/usb-musb.c, that is because the code in there handles STALL and NAK specially and has a if status < 0 generic catch all for all other errors Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-03-07usb-ehci: Fix and simplify nakcnt handlingHans de Goede1-28/+4
The nakcnt code in ehci_execute_complete() marked transactions as finished when a packet completed with a result of USB_RET_NAK, but USB_RET_NAK means that the device cannot receive / send data at that time and that the transaction should be retried later, which is also what the usb-uhci and usb-ohci code does. Note that there already was some special code in place to handle this for interrupt endpoints in the form of doing a return from ehci_execute_complete() when reload == 0, but that for bulk transactions this was not handled correctly (where as for example the usb-ccid device does return USB_RET_NAK for bulk packets). Besides that the code in ehci_execute_complete() decrement nakcnt by 1 on a packet result of USB_RET_NAK, but -since the transaction got marked as finished, nakcnt would never be decremented again -there is no code checking for nakcnt becoming 0 -there is no use in re-trying the transaction within the same usb frame / usb-ehci frame-timer call, since the status of emulated devices won't change as long as the usb-ehci frame-timer is running So we should simply set the nakcnt to 0 when we get a USB_RET_NAK, thus claiming that we've tried reload times (or as many times as possible if reload is 0). Besides the code in ehci_execute_complete() handling USB_RET_NAK there was also code handling it in ehci_state_executing(), which calls ehci_execute_complete(), and then does its own handling on top of the handling in ehci_execute_complete(), this code would decrement nakcnt *again* (if not already 0), or restore the reload value (which was never changed) on success. Since the double decrement was wrong to begin with, and is no longer needed now that we set nakcnt directly to 0 on USB_RET_NAK, and the restore of reload is not needed either, this patch simply removes all nakcnt handling from ehci_state_executing().

2012-03-07usb-ehci: Remove dead nakcnt codeHans de Goede1-20/+0
This patch removes 2 bits of dead nakcnt code: 1) usb_ehci_execute calls ehci_qh_do_overlay which does: nakcnt = reload; and then has a block of code which is conditional on: if (reload && !nakcnt) { which ofcourse is never true now as nakcnt == reload. 2) ehci_state_fetchqh does: nakcnt = reload; but before nakcnt is ever used ehci_state_fetchqh is always followed by a ehci_qh_do_overlay call which also does: nakcnt = reload; So doing this from ehci_state_fetchqh is redundant.

2012-03-07usb-ehci: Fix cerr trackingHans de Goede1-13/+6
cerr should only be decremented on errors which cause XactErr to be set, and when that happens the failing transaction should be retried until cerr reaches 0 and only then should USBSTS_ERRINT be set (and inactive cleared and USBSTS_INT set if requested). Since we don't have any hardware level errors (and in case of redirection the real hardware has already retried), re-trying makes no sense, so immediately set cerr to 0 on errors which set XactErr.
