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

In order to be meaningful and usable together with other measuring methods, their use in my opinion should impose as little overhead as possible. With that, I wonder why per-cpu counters use atomic operations.

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.

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

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.

My recent interest in the TPR-write problem has got me thinking about if there is any other optimisation that could be done for windows, especially as a few people have reported issues with more than a few processors, and they say they are already running 2K3sp2 which should have TPR optimisation in it already. Is there any facility currently for profiling the frequency of vmexit''s to

Guys, OK, now that we have the new core contributors squared away, we can go back to finishing the contributors list. There were some people who got added and then there is existing contributors list. I think Darren''s suggestion to wait to add new core contributors is fine (let the new constitution settle down and we can in the meanwhile have a more inclusive look at both rather than

Updated set of patches for coverage. Changes: - change copyright lines - use gcov: instead of cover: in commit comment - use #ifdef in xen/common/sysctl.c instead of dummy inline function - added base documentation in docs/misc - added -h option to xencov

In crossbow, each mac_srs has a kernel thread called "mac_rx_srs_poll_ring" to poll the hardware and crossbow will wakeup this thread to poll packets from the hardware automatically. Does crossbow provide any method to disable the polling mechanism, for example disabling the this kernel thread?

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

Hello, I am Abhinav Tripathi, B.Tech 3rd Year student from IIT Indore, India. I was looking on the projects ideas page of llvm and saw that I could also propose to work on the SAFECode Open projects.

I found most of the projects quite alluring as I have been working on a

I've resolved the conflicts between the xen-unstable svn tree's patchset and xen-unstable 16319 (which was the tip a few days ago). The result is below, as the output of `svn diff' - so a series of interdiffs, unfortunately. Also, I noticed that after installing the resulting packages, it wasn't able to correctly select the xen-unstable tools; instead, it fell back to the default.

Hi, Keir, Currently, HVM guests do not have access to performance counters. So it is not possible to use performance analyzer software such as vtune in HVM guest to analyze programme performance. Other usage of performance counters , for example, the NMI watchdog, won''t function either. This patch will enable performance counters in HVM guest. Currently, only Core 2 Duo is implemented.
