According to the Book3S spec, the interrupt context starts with an MSR value that is rather simple. If we leave out the HV case, it's almost always 0. To reflect this, let's redesign the way that MSR value gets calculated. Using this, we also squash the bug where MSR_POW can slip through into the interrupt handler MSR.

The lwarx and ldarx instructions have a bit to give some hint to the CPU which is safe to ignore. We currently refuse to accept any instruction with that bit set, as it used to be declared MBZ. Let's remove the reserved bit and make the instruction work as expected. This fixes Linux boot for ppc64.

Sending ESP a command caused it to trigger DMA immediately even if DMA was not enabled at the DMA controller. Add a signal from DMA controller to ESP to tell ESP about changes in DMA enable bit. Also use the correct function for setting up GPIO outputs. This fixes NetBSD 1.6.1 through 3.0 boot. Thanks to Artyom Tarasenko for extensive debugging of the problem.

Janne Huttunen noticed that the FIFO end pointer is updated by the guest after writing each word to the FIFO, at least the X.org driver which is open does this. This means that there's no way for the host to know if the guest is in the middle a write operation. Qemu thus needs to read the beginning of the command up to when it's able to tell how many words are expected for the given command. It will abort reading and rewind the FIFO if there aren't enough words yet, this should be relatively rare but it is suspected to have been the cause of the occasional FIFO overrun that killed the display.

Character devices created by qemu_chr_open don't allow duplicate device names, so naming all UART devices "null" no longer works. Running "qemu-system-arm -M n800" (and some other machines) results in this error message: qemu-system-arm: Duplicate ID 'null' for chardev Can't create serial device, empty char device This is fixed by setting a default label "uart1", "uart2" or "uart3".

This patch adds the trace-file command: trace-file [on|off|flush] Open, close, or flush the trace file. If no argument is given, the status of the trace file is displayed. The trace file is turned on by default but is only written out when the trace buffer becomes full. The flush operation can be used to force write out at any time. Turning off the trace file does not change the state of trace events; tracing will continue to the trace buffer. When the trace file is off, use "info trace" to display the contents of the trace buffer in memory.

Allow users to specify a file for trace-outputs at configuration. Also, allow trace files to be annotated by <pid> so each qemu instance has unique traces. The trace file name can be passed as a config option: --trace-file=/path/to/file (Default: trace ) At runtime, the pid of the qemu process is appended to the filename so that mutiple qemu instances do not have overlapping logs. Eg : trace-1234 for qemu launched with pid 1234. I have yet to test this on windows. getpid() is used at many places in code(including vnc.c), so I'm hoping this would be okay too.

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 adds support for dynamically enabling/disabling of trace events. This is done by internally maintaining each trace event's state, and permitting logging of data from a trace event only if it is in an 'active' state. Monitor commands added : 1) info trace-events : to view all available trace events and their state. 2) trace-event NAME on|off : to enable/disable data logging from a given trace event. Eg, trace-event paio_submit off disables logging of data when paio_submit is hit. By default, all trace-events are disabled. One can enable desired trace-events via the monitor.

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.
