* usb-storage: switch trace eventsGerd Hoffmann2020-11-161-0/+12

* dev-serial: store flow control and xon/xoff charactersMark Cave-Ayland2020-11-041-0/+2
| | | | | | | | | | | | | Note that whilst the device does not do anything with these values, they are logged with trace events and stored to allow future implementation. The default flow control is set to none at reset as documented in the Linux ftdi_sio.h header file.

* trace-events: Fix attribution of trace points to sourceMarkus Armbruster2020-09-091-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some trace points are attributed to the wrong source file. Happens when we neglect to update trace-events for code motion, or add events in the wrong place, or misspell the file name. Clean up with help of scripts/cleanup-trace-events.pl. Funnies requiring manual post-processing: * accel/tcg/cputlb.c trace points are in trace-events. * block.c and blockdev.c trace points are in block/trace-events. * hw/block/nvme.c uses the preprocessor to hide its trace point use from cleanup-trace-events.pl. * hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to guard debug code. * include/hw/xen/xen_common.h trace points are in hw/xen/trace-events. * linux-user/trace-events abbreviates a tedious list of filenames to */signal.c. * net/colo-compare and net/filter-rewriter.c use pseudo trace points colo_compare_miscompare and colo_filter_rewriter_debug to guard debug code.

* usb: add hostdevice property to usb-hostGerd Hoffmann2020-06-171-0/+1
| | | | | | | | | | | | | The new property allows to specify usb host device name. Uses standard qemu_open(), so both file system path (/dev/bus/usb/$bus/$dev on linux) and file descriptor passing can be used. Requires libusb 1.0.23 or newer. The hostdevice property is only present in case qemu is compiled against a new enough library version, so the presence of the property can be used for feature detection.

* dwc-hsotg (dwc2) USB host controller emulationPaul Zimmerman2020-06-051-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the dwc-hsotg (dwc2) USB host controller emulation code. Based on hw/usb/hcd-ehci.c and hw/usb/hcd-ohci.c. Note that to use this with the dwc-otg driver in the Raspbian kernel, you must pass the option "dwc_otg.fiq_fsm_enable=0" on the kernel command line. Emulation of slave mode and of descriptor-DMA mode has not been implemented yet. These modes are seldom used. I have used some on-line sources of information while developing this emulation, including: http://www.capital-micro.com/PDF/CME-M7_Family_User_Guide_EN.pdf which has a pretty complete description of the controller starting on page 370. https://sourceforge.net/p/wive-ng/wive-ng-mt/ci/master/tree/docs/DataSheets/RT3050_5x_V2.0_081408_0902.pdf which has a description of the controller registers starting on page 130. Thanks to Felippe Mathieu-Daude for providing a cleaner method of implementing the memory regions for the controller registers.

* usb-host: remove 'remote wakeup' flag from configuration descriptorYuri Benditovich2020-01-131-0/+1
| | | | | | | | | | | | | | | | If the redirected device has this capability, Windows guest may place the device into D2 and expect it to wake when the device becomes active, but this will never happen. For example, when internal Bluetooth adapter is redirected, keyboards and mice connected to it do not work. Current commit removes this capability (starting from machine 5.0) Set 'usb-host.suppress-remote-wake' property to 'off' to keep 'remote wake' as is or to 'on' to remove 'remote wake' on 4.2 or earlier.

| | | | | | | | | | | | | | | We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.
