* Fix emacs local variable block to use correct C style variable.David Vrabel2013-02-211-1/+1
| | | | | | | The emacs variable to set the C style from a local variable block is c-file-style, not c-set-style. Signed-off-by: David Vrabel <david.vrabel@citrix.com
* libxc: convert evtchn interfaces to use an opaque handle typeIan Campbell2010-12-231-8/+7
| | | | | | | | | | | | This makes the interface consistent with the changes made to the main interface in 21483:779c0ef9682c. Also fix some references to "struct xc_interface" which should have been simply "xc_interface" in tools/xenpaging, and update QEMU_TAG to pull in the corresponding qemu change.

* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-7/+7
| | | | | | | | | | | | | | | | | | | | This patch eliminate the global variables in libxenctrl (used for logging and error reporting). Instead the information which was in the global variables is now in a new xc_interface* opaque structure, which xc_interface open returns instead of the raw file descriptor; furthermore, logging is done via xentoollog. There are three new parameters to xc_interface_open to control the logging, but existing callers can just pass "0" for all three to get the old behaviour. All libxc callers have been adjusted accordingly. Also update QEMU_TAG for corresponding qemu change. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* xentrace: Add an option not to enable tracingKeir Fraser2010-04-131-2/+16
| | | | | | | | | Add an option that will set up the buffers and listen for updates, but will not enable tracing. This is useful if you have hacks in Xen to enable tracing at key points (for example, debugging a shadow bug). Signed-off-by: George Dunlap <george.dunlap@eu.citrix.com>
* xentrace: Skip to low cpu when throwing away portions of the circular bufferKeir Fraser2010-04-131-0/+15

* xentrace: Disable tracing, then read records one more time.Keir Fraser2010-02-031-4/+14
| | | | | | | | | | | When interrupted, first disable tracing, then read through the records one last time. Without this patch, it's possible to get traces which interact (such as runstate changes) on processors with higher numbers, while missing the corresponding traces generated on lower-numbered processors.

* xentrace: Per-cpu xentrace buffersKeir Fraser2010-01-201-73/+60
| | | | | | | | | | | | | | | | In the current xentrace configuration, xentrace buffers are all allocated in a single contiguous chunk, and then divided among logical cpus, one buffer per cpu. The size of an allocatable chunk is fairly limited, in my experience about 128 pages (512KiB). As the number of logical cores increase, this means a much smaller maximum per-cpu trace buffer per cpu; on my dual-socket quad-core nehalem box with hyperthreading (16 logical cpus), that comes to 8 pages per logical cpu. This patch addresses this issue by allocating per-cpu buffers separately. Signed-off-by: George Dunlap <dunlapg@umich.edu>

* xentrace: Allow xentrace to handle >4G of trace data.Keir Fraser2008-02-111-2/+11
| | | | | | | | | | | | | It was previously assert'ing when it hit 4G. Also, because the trace buffer is not a power of 2 in size, using modulo arithmetic to address the buffer does not work when the index wraps around 2^32. This patch fixes both issues, and as a side effect, removes all integer division from the hypervisor side of the trace mechanism. Signed-off-by: Michael A Fetterman <Michael.Fetterman@cl.cam.ac.uk>
* xentrace: Don't append trace on existing file.Keir Fraser2007-12-041-7/+7
| | | | | | | | | | | | | When you run "xentrace -e <mask> trace.output" the first time, all is fine. When you run it a second time, then the data is appended which makes you reading old data with xentrace_format and you interprete it as new data. This usually happens when you automated tracing guests with xentrace and xentrace_format with a script. Therefore, attached patch makes xentrace to truncate the file to zero bytes before writing any data. Signed-off-by: Christoph Egger <Christoph.Egger@amd.com>

* [xen][tracing] Introduce variable-size trace recordsGeorge Dunlap2007-09-211-28/+104
| | | | | | | | | | | | | | | | | | | This patch introduces variable-size trace records. Each record consists of a 32-bit "header", an optional cycle count, and up to seven more 32-bit words. The header is packed with the following information: bits 0-27: The trace event. bits 28-30: The number of 32-bit "extra" words in the records bit 31: Does the trace include a 64-bit tsc? This patch standardizes behavior wrt 32 and 64-bit hypervisors and dom0s. Note that this patch requires a new version of the xentrace daemon running in dom0. The new daemon, instead of pre-pending the cpu to every record as it writes it, inserts a "cpu change" record to the trace file that record the cpu and the number of records it's about to write.
