trace: Add trace-events file for declaring trace events 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. This commit includes fixes from Prerna Saxena <prerna@linux.vnet.ibm.com> and Blue Swirl <blauwirbel@gmail.com>. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

# Trace events for debugging and performance instrumentation
#
# This file is processed by the tracetool script during the build.
#
# To add a new trace event:
#
# 1. Choose a name for the trace event. Declare its arguments and format
# string.
#
# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() ->
# trace_multiwrite_cb(). The source file must #include "trace.h".

trace: Support disabled events in trace-events 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: Stefan 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.

usb: data structs and helpers for usb descriptors. 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: Gerd Hoffmann <kraxel@redhat.com>

xen: Introduce the Xen mapcache On IA32 host or IA32 PAE host, at present, generally, we can't create an HVM guest with more than 2G memory, because generally it's almost impossible for Qemu to find a large enough and consecutive virtual address space to map an HVM guest's whole physical address space. The attached patch fixes this issue using dynamic mapping based on little blocks of memory. Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the lock option, so mapcache will not unmap these ram_ptr. Blocks that do not belong to the RAM, but usually to a device ROM or to a framebuffer, are handled in a separate function. So the whole RAMBlock can be map.

Introduce qemu_put_ram_ptr This function allows to unlock a ram_ptr give by qemu_get_ram_ptr. After a call to qemu_put_ram_ptr, the pointer may be unmap from QEMU when used with Xen.

coroutine: introduce coroutines Asynchronous code is becoming very complex. At the same time synchronous code is growing because it is convenient to write. Sometimes duplicate code paths are even added, one synchronous and the other asynchronous. This patch introduces coroutines which allow code that looks synchronous but is asynchronous under the covers. A coroutine has its own stack and is therefore able to preserve state across blocking operations, which traditionally require callback functions and manual marshalling of parameters. Creating and starting a coroutine is easy: coroutine = qemu_coroutine_create(my_coroutine); qemu_coroutine_enter(coroutine, my_data); The coroutine then executes until it returns or yields: void coroutine_fn my_coroutine(void *opaque) { MyData *my_data = opaque; /* do some work */ qemu_coroutine_yield(); /* do some more work */ } Yielding switches control back to the caller of qemu_coroutine_enter(). This is typically used to switch back to the main thread's event loop after issuing an asynchronous I/O request. The request callback will then invoke qemu_coroutine_enter() once more to switch back to the coroutine. Note that if coroutines are used only from threads which hold the global mutex they will never execute concurrently. This makes programming with coroutines easier than with threads. Race conditions cannot occur since only one coroutine may be active at any time. Other coroutines can only run across yield. This coroutines implementation is based on the gtk-vnc implementation written by Anthony Liguori <anthony@codemonkey.ws> but it has been significantly rewritten by Kevin Wolf <kwolf@redhat.com> to use setjmp()/longjmp() instead of the more expensive swapcontext() and by Paolo Bonzini <pbonzini@redhat.com> for Windows Fibers support.
