similar to: Unable to use software counters

Hi All I want to use software counters available via "xenperf". However I get this error "Error getting number of perf counters: 38 (Function not implemented)". Am I missing something? Some configuration or option which needs to be turned on before I can use these counters. Any help would be much appreciated. I am using Xen 3.1.0 x86_64 -- Jyotirmaya Tripathi Virginia Tech

Hello, Even I think it would be a very big project for just 3 months, but it would be fun learning and developing this. I feel I have the required skills and would like to learn more for this. I have just one doubt regarding the GPU required for the task. Will a normal NVIDIA GT 740m would be enough or we need better GPUs like Tesla or Quadro? In the latter case how can one proceed in case of its

There's not a lot of information about it. Basically we need 2 instruction scheduling passes -- one pre-RA and one post-RA. The prerequisites are "know how compilers work" and "have a GPU that you can test performance on". I won't beat around the bush - this is a very tough project. Every attempt at it so far has basically failed. There are a lot of issues that have to

Hi, I think a nice project would be to write an application to figure out those latencies automatically maybe even based on envydis. It could generate latency information based on thread count, register usage, instruction/instruction class, hw unit used. Or even tries to figure out what kind of units exist. Like instructions out of a group which are free to issue/execute after instructions out

Hello, I am quite interested in the project "Instruction Scheduler" under X.org. Please tell me where can I find a detailed idea of the project and how to start it. I think I have the given prerequisites. Regards Shailesh Tripathi Shailesh Tripathi B.Tech.

Hi, this is almost an ia64 specific patch to xenperf. It makes xenperf output more understandable. On x86, it now displays hypercalls name. Tested on xen/ia64.

Hi all, I have dom0 and a guest on the same cpu: cpu0. However, when I look at interrupts and ipis (with Xenperf) I get the following. There is nothing going on Cpu3 so why the high number of IPIs? I have done a reset of the counters, but after I run my workload on the guest cpu3 IPIS go from 0 to 210276 (Dom- has only 1 cpu and xm vcpu-list shows the other 3 cpus in blocked state. The

This patch pretty prints the hypercall section for $xenperf -f Each hypercall count is tagged by its name.

Hi, Since long time ago, to enable the SR-IOV VF pci passthrough function, I'm always adding "amd_iommu=on" into kernel cmdline on AMD system. But recently I found even I do not do this action, IOMMU is still enabled by kernel on AMD system. After searching, I found there is no such setting any more, refer to

Hi! I have implemented a security feature in LLVM and now I want to evaluate the performance impact by comparing the perf profile of the originally compiled program and the modified program. For that I have run a benchmark with lnt runtest test-suite and -use-perf=all. I can compare the recorded counters in the lnt runserver webinterface perfectly fine with the side by side comparison. However,

Hello, Every queue has some status counters (completed, abandoned, hold time...) that are very useful for statistics. The problem is that those counters are reset every time Asterisk restarts. Is there a way to keep those counters, maybe in astdb? Also, is there a way to reset the counters through a cli command? Thanks. -- MARLON DUTRA Propus GnuPG ID: 0x3E2060AC pgp.mit.edu

I am acquiring some sampled data that is time-stamped (with a POSIXct). Some of the data is in the form of "counters" -- that is, what is interesting isn't value of a given counter at a given time, but the change in the counter from one sample to a later one. As the counters are only incremented, they would be perceived to be monotonically increasing -- ideally. Unfortunately, the
