* hw/qxl: qxl_send_events: nop if stoppedAlon Levy2013-01-121-0/+1
| | | | | | | | | | Added a trace point for easy logging. RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=870972 Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> (cherry picked from commit 511aefb0c60e3063ead76d4ba6aabf619eed18ef)
* hw/qxl: tracing fixesAlon Levy2012-11-131-2/+4
| | | | | | | | | | | | | | | | | | Add two new trace events: qxl_send_events(int qid, uint32_t events) "%d %d" qxl_set_guest_bug(int qid) "%d" Change qxl_io_unexpected_vga_mode parameters to be equivalent to those of qxl_io_write for easier grouping under a single systemtap probe. Change d to qxl in one place.

* ehci: switch to new-style memory opsGerd Hoffmann2012-11-131-3/+6
| | | | | | | | | | | | | | | | | | | Also register different memory regions for capabilities, operational registers and port status registers. Create separate tracepoints for operational regs and port status regs. Ditch a bunch of sanity checks because the memory core will do this for us now. Offloading the byte, word and dword access handling to the memory core also has the side effect of fixing ehci register access on bigendian hosts.

* xhci: drop bufferingGerd Hoffmann2012-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch splits the xhci_xfer_data function into three. The xhci_xfer_data function used to do does two things: (1) copy transfer data between guest memory and a temporary buffer. (2) report transfer results to the guest using events. Now we three functions to handle this: (1) xhci_xfer_map creates a scatter list for the transfer and uses that (instead of the temporary buffer) to build a USBPacket. (2) xhci_xfer_unmap undoes the mapping. (3) xhci_xfer_report sends out events. The patch also fixes reporting of transaction errors which must be reported unconditinally, not only in case the guest asks for it using the ISP flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revision bumped to 4 for new IO support, enabled for spice-server >= 0.11.1. New io enabled if revision is 4.

Once we have a new stable spice-server release and the qemu patches to enable the new bits merged we'll go flip the switch and make rev4 the default ] This io calls the corresponding new spice api spice_qxl_monitors_config_async to let spice-server read a new guest set monitors config and notify the client.

* pseries: Add PCI MSI/MSI-X supportAlexey Kardashevskiy2012-08-151-0/+5
| | | | | | | | | | | | | | | | | | | | | | | This patch implements MSI and MSI-X support for the pseries PCI host bridge. To do this it adds: * A "config_space_address to msi_table" map, since the MSI RTAS calls take a PCI config space address as an identifier. * A MSIX memory region to catch msi_notify()/msix_notiry() from virtio-pci and pass them to the guest via qemu_irq_pulse(). * RTAS call "ibm,change-msi" which sets up MSI vectors for a device. Note that this call may configure and return lesser number of vectors than requested. * RTAS call "ibm,query-interrupt-source-number" which translates MSI vector to interrupt controller (XICS) IRQ number.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | $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.

* Add rate limiting of RTC_CHANGE, BALLOON_CHANGE & WATCHDOG eventsDaniel P. Berrange2012-06-151-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Allow certain event types to be rate limited to avoid flooding monitor clients. The monitor_protocol_event() method is changed such that instead of immediately emitting the event to Monitor instances, it will call a new monitor_protocol_event_queue() method. This will check to see if the rate limit for the event has been exceeded, and if so schedule a timer to wakeup at the end of the rate limit period. If further events arrive before the timer fires, the previously queued event will be discarded in favour of the new event. The event will eventually be emitted when the timer fires. This logic is applied to RTC_CHANGE, BALLOON_CHANGE & WATCHDOG events, since the data associated with these events is stateless * monitor.c: Add support for rate limiting * monitor.h: Define monitor_global_init for one-time setup tasks * vl.c: Invoke monitor_global_init * trace-events: Add hooks for monitor event tracing Signed-off-by: Daniel P.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch carries a complete rewrite of the usb descriptor parser. Changes / improvements: * We are using the USBDescriptor struct instead of hard-coded offsets now to access descriptor data. * (debug) printfs are all gone, tracepoints have been added instead. * We don't try (and fail) to skip over unneeded descriptors. We parse them all one by one. We keep track of which configuration, interface and altsetting we are looking at and use this information to figure which desciptors are in use and which we can ignore. * On parse errors we clear all endpoint information, which will disallow any communication with the device, except control endpoint messages. This makes sure we don't end up with a silly device state where half of the endpoints got enabled and the other half was left disabled. * Some sanity checks have been added. The new parser is more robust and also leaves complete device information in the trace log if you enable the ush_host_parse_* tracepoints. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
