Does xentrace write into buffers by default?
Hello, I have a question about the way Xentrace takes a trace. In previous versions of Xen, I took a trace by setting the size of buffers, activating them and writing the information into a file (optional). setsize 20 tbctl 1 xentrace /tmp/xentrace.dat Now I''m using xen-unstable and I see that setsize is already integrated in xentrace command. My question is: does start/stop buffer is

xentrace
Hi, I've made some SAP benchmarks on my Xen system and discovered a huge difference in the performance of a "xened" SAP system compared to a native SAP system. Hence, I tried to figure out what might cause this 'overhead' and run a xentrace (listining to all events). Xentrace produced 24gb data and I converted it to 27gb human-readable data. After I gathered the

[PATCH] xentrace event mask for memory management class
Since TRC_MEM is defined as 0x000af000 in xen/include/public/trace.h, TRC_MEM = TRC_SCHED | TRC_VMX. I feel strange about this. I do not think scheduling is a part of memory management. Am I right? If not, please tell me the background TRC_MEM is defined as TRC_SCHED | TRC_VMX. If so, please apply this patch. This patch defines TRC_MEM as an independent event mask. In addition, xentrace

xentrace and MSR_READ/MSR_WRITE
I am trying to learn some more about the way windows does TPR writes, and tried xentrace for the first time. I did ''xentrace --time-interval=5 xentrace.out'' to capture some data, and then ran it through ''xentrace_format'' using the supplied example defs file. I can see some PF_XEN entries with virt=0xFFFE0080 (address of TPR), but I want to know the value being

[PATCH][xentrace][HVM] introduce HVM tracing to unify SVM and VMX tracing
Hello, this patch introduces HVM tracing: one tracing class for both, SVM and VMX. It adds several new trace events. So we can differentiate between them in the xentrace formats file and format each event''s data items appropriately. With this patch the xentrace_format output is much more informative. The previous simple tracing in SVM and VMX is completely replaced. Unfortunately I

[PATCH] Make xentrace hypercall a bit more sane
xentrace, setsize and the hypervisor don''t seem to be on the same page. If tracing is not enabled, the hypercall will only allow TBUF_SET_SIZE and TBUF_ENABLE. However, set_size calls TBUF_GET_INFO, and xentrace wants to call TBUF_SET_EVT_MASK and TBUF_SET_CPU_MASK before calling TBUF_ENABLE. I don''t see any reason not to call SET_*_MASK and GET_INFO if tracing is not enabled.

Problem correlating TSC read from domU with Xentrace's TSC
Hi, I am trying to correlating performance issue in guest VM with the scheduling trace from Xentrace. User-mode application in guest VM periodically dump APIC ID and RDTSC into trace. I also start Xentrace in Dom0 during the same period. However, I notice that range of TSC values report both trace is completely disjointed. TSC values from Xentrace is always greater than what guest VM see, even

how to use xentrace and xentrace_format
Hi, I have read a mail in the mail list about xentrace and xentrace_format. But I am still puzzled on how to use them. Could somebody give me an example about how to use xentrace and xentrace_format. What I have done is that: 1. Root:/# xentrace /var/perftests/xentrace.log Then I use xentrace_format to get what I want 2. cat /var/perftests/xentrace.log | xentrace_format

How to enable Xentrace in xen-unstable?
Hi, I am using xen-unstable and interested to trace the hypervisor. In previous versions, I was able to trace it by: setsize 20 tbctl 1 xentrace /tmp/xentrace.dat And these functions don''t exist in xen-unstable. xentrace --help shows that in more recent versions the buffers'' size could be determined as a parameter for xentrace. But I can not find any replacement for

[PATCH 5/6] xen, tools: calculate nr_cpus via num_online_cpus
Once Xen calculates nr_nodes properly, all nr_cpu calculations based on nr_nodes * sockets_per_node * cores_per_socket * threads_per_core are broken. The easy fix is to replace those calculations with a new field, nr_cpus in physinfo which is calculated by num_online_cpus(). This patch does so and attempts to change all users over to nr_cpus field in physinfo. This patch touches

xentrace: cycles error
Hi All, I am running xentrace on an idle machine (dom0 has 2 cpus). There are 4 cpus in the system > date xentrace -e0x82000 > idle.out date The sampling interval is 25 seconds. However when I format and look at the output, I see the sample time is 761 seconds or something bizarre Looks like the cpu cycles have gone beserk. Any ideas as to what could be happening thanks Prabha
