Hi, Is anybody know the purpose of this method (xen_evtchn_do_upcall)? When I run a user level application involved in TCP receiving and the SoftIRQ for eth0 on the same CPU core, everything is OK. But if I run them on 2 different cores, there will be xen_evtchn_do_upcall() existing (maybe when the local_bh_disable<http://www.cs.fsu.edu/~baker/devices/lxr/http/ident?i=local_bh_disable>() or

Since the image pointed to may (and generally will) live in boot services memory (which we add to the global memory pool long before ACPI tables get looked at), we should prevent Dom0 from trying to retrieve the image data. The alternatives would be to - not add boot services memory to the global pool at all, or - defer adding boot services memory until Dom0 indicates it is safe to do so, or -

Hi, I''m still seeing a very strange issue here. First, let''s clarify that the issue has never occurred with the good old xen 3.x and the good old 2.6.18 kernel. So the issue is, that with xen 4.x (including 4.1.1) pretty much any kernel (including kernel from [1] and vanilla 3.0.0, didn''t test the 2.6.18), the machine freezes during a reboot. The machine won''t

Dear R-helpers, New to R, I'm in the middle of a project that I'm using to force me learn R. I'm running into some behavior that I don't understand, and I need some advice. In the last week I've gotten some great advice from the list on visualizing my data, and I was hoping people could help me get over another barrier I've encountered to my progress. Before I

Hello. I am hoping someone can help with a problem I am having. I am running the Windows folding at home client through wine. This app is very load intensive and performs many scientific calculations. It consumes 100% of all six cores in my system. However, I run it with a "nice" level of 19 so that it only uses idle cycles. Unfortunately, with this setup, my system consistently

Now that the scheduler can deal with migrate disable properly, there is no real compelling reason to make it only available for RT. There are quite some code pathes which needlessly disable preemption in order to prevent migration and some constructs like kmap_atomic() enforce it implicitly. Making it available independent of RT allows to provide a preemptible variant of kmap_atomic() and makes

Hej folks, I''ve been trying to get a new machine up and running with the latest Xen for a while on a Slackware64 (current) machine. After installing Xen from source and building a new kernel with all xen options enabled I haven''t been able to get the machine to behave. The machine is a brand new dual opteron 6212 on a Supermicro H8DGi board with 64G ECC memory. Running a stock

Hello, I am building a home file server and am looking for an ATX mother board that will be supported well with OpenSolaris (onboard SATA controller, network, graphics if any, audio, etc). I decided to go for Intel based boards (socket LGA 775) since it seems like power management is better supported with Intel processors and power efficiency is an important factor. After reading several

Hi Jan, After commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, booting dom0 stalls several times. Sometimes this results in RCU stall warnings from the dom0 kernel, hitting the "any" key, on normal or serial console, makes the boot continue for a while but it stalls several times. (It also stalls on shutdown BTW) I have
