[PATCH][XM-TEST] Fix bugzilla # 674 by changing the xm-test Console.py to wait for the command prompt.
...o run. DO NOT APPLY. This patch is FOR REVIEW ONLY at this stage since my python skills are pretty lame and it really needs to get some testing from people who have actually been experiencing problems. For me, xm-test works the same on my machine with and without this patch.

Bug in use of grant tables in blkback.c error path?
...and attempt to map the remaining pages after an error is encountered. All in all, this looks like a bug to me where failure to map a grant reference in the middle of a set would result in pages kept mapped in the backend when fast_flush_area fails to clean them up. Am I right?

latest USB code
Here''s the latest USB code against the xen 3.0.0 release. Since the last posting this version updates the code to use the new 32 bit grant references and the latest GNTTABOP_map_grant_ref definition. I''ve also changed the definition of the virtual USB HCD to have a single port rather than seven ports with six unused. Domains importing multiple USB devices will get a HCD for

PATCH: Port equalloudfilt.m MATLAB to scilab
Although the script doesn't generate identical results, it seems to get fairly close. The deviations for the Butterworth filter settings seem larger than for the equal loudness filter. This script requires OpenSource scilab which is available for Windows, Linux and MacOS. http://www.scilab.org/products/scilab/download Earl -------------- next part -------------- A non-text attachment was scrubbed...

low pass filter analysis in R
Hello R users, I am trying to use R to do the low pass filter analysis for the tidal data. I am a novice in R and so far been doing only simple stuffs on R. I found a package called signal but couldn't find the proper tutorial for the low pass filter. Could anyone point me to the proper tutorial or starting point on how to do low pass filter analysis in R ? Thank you so much. Janesh

distances from points to line
Dear all, I have discovered that there are many things that I used to do in my GIS which are easily done directly in R, for example calculating interpoint distances using geoR and pick out points inside a polygon using splancs. I now wonder, is there a function to create a line object like a watercourse and then calculate the distances between many points in space and this line? I couldn't

...e implements several time series filters useful for smoothing and extracting trend and cyclical components of a time series. The routines are commonly used in economics and finance, however they should also be interest to other areas.

[PATCH] fast_flush_area in blkback.c still broken after 55194bd55b86
...TTABOP_unmap_grant_ref in fast_flush_area. Also, I think the memset of the pending_grant_handles array should happen before you start using them so I moved it to before blkif_xenbus_init. I''m not sure if this is necessary or it might possibly have to go even earlier.

[PATCH][5/17] USB virt 2.6 split driver---concrete local buffer reference types
This patch implements a local buffer reference type for kernel virtual address space and a remote buffer reference type for buffers up to 16 pages based on grant tables. These types are used by the USB driver for bulk data transfer.

[LLVMdev] incorrect x86 instruction size calculation
Hello, I'm trying to write some backends for LLVM that generate code that complies with SFI validation rules by re-implementing SFI for the LLVM x86 backend based on the Google NaCl project. However, in trying to implement 32-byte code alignment, X86InstrInfo::GetInstSizeInBytes() is returning incorrect instruction sizes for certain instructions (that I have seen so far): MOV32mi,

USB frontend and backend disappeared from latest unstable tree
