This patch moves setting and clearing the remote_wakeup feature bit (via USB_REQ_{SET,CLEAR}_FEATURE) to common code. Also USB_REQ_GET_STATUS handling is moved to common code. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This patch adds fields to the USBDevice struct for the current speed (hard-wired to full speed for now) and current device configuration. Also a init function is added which inializes these fields. This allows USB_REQ_{GET,SET}_CONFIGURATION handling to be moved to common code. For most drivers the conversion is trivial ad they support a single configuration only anyway. One exception is bluetooth where some device-specific setup code runs after get/set configuration. The other is usb-net which actually has two configurations so the the code to check for the active configuration has been adapted. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This patch adds hw/usb-desc.[ch] files. They carry data structures for various usb descriptors and helper functions to generate usb packets from the structures. The intention is to have a internal representation of the device desription which is more usable than the current char array blobs, so we can have common code handle common usb device emulation using the device description. The usage of this infrastructure is optional for usb drivers as there are cases such as pass-through where it probably isn't very useful. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This patch implements the read/write state machine. Operations are fully asynchronous and multiple operations may be active at any time. Allocating writes lock tables to ensure metadata updates do not interfere with each other. If two allocating writes need to update the same L2 table they will run sequentially. If two allocating writes need to update different L2 tables they will run in parallel. Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch adds code to look up data cluster offsets in the image via the L1/L2 tables. The L2 tables are writethrough cached in memory for performance (each read/write requires a lookup so it is essential to cache the tables). With cluster lookup code in place it is possible to implement bdrv_is_allocated() to query the number of contiguous allocated/unallocated clusters.

It is not portable to use "%ld" for int64_t because int64_t may have type long on 64-bit platforms and long long on 32-bit platforms.

Sometimes it is useful to disable a trace event. Removing the event from trace-events is not enough since source code will call the trace_*() function for the event. This patch makes it easy to build without specific trace events by marking them disabled in trace-events: disable multiwrite_cb(void *mcb, int ret) "mcb %p ret %d" This builds without the multiwrite_cb trace event. Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com> trace: Allow bulk enabling/disabling of trace events at compile time For 'simple' trace backend, allow bulk enabling/disabling of trace events at compile time. Trace events that are preceded by 'disable' keyword are compiled in, but turned off by default. These can individually be turned on using the monitor. All other trace events are enabled by default. TODO : This could be enhanced when the trace-event namespace is partitioned into a group and an ID within that group. In such a case, marking a group as enabled would automatically enable all trace-events listed under it.

This patch introduces the trace-events file where trace events can be declared like so: qemu_malloc(size_t size) "size %zu" qemu_free(void *ptr) "ptr %p" These trace event declarations are processed by a new tool called tracetool to generate code for the trace events. Trace event declarations are independent of the backend tracing system (LTTng User Space Tracing, ftrace markers, DTrace). The default "nop" backend generates empty trace event functions. Therefore trace events are disabled by default. The trace-events file serves two purposes: 1. Adding trace events is easy. It is not necessary to understand the details of a backend tracing system. The trace-events file is a single location where trace events can be declared without code duplication. 2. QEMU is not tightly coupled to one particular backend tracing system. In order to support tracing across QEMU host platforms and to anticipate new backend tracing systems that are currently maturing, it is important to be flexible and not tied to one system.
