...following... I've got a list (returned from a function) and I would like to "cbind()" the lists together to create a "cross tab" report or simply bind them together somehow the function returns a list that looks like the following: > all$BM $species [1] "BM" $vbar.nobs [1] 3 $vbar.sum [1] 54.05435 $count.nobs [1] 20 $basal.area [1] 26 $expf [1] 5.339182 > so there are different variable types in the list (meaning I can't use cbind?) to create a table with more than one column for stringing together multiple species. I tried to use rbind and got simi...

...examples, although it works for the second. By fails, I mean it returns NULL. ---------- example 1 ---------- test1(int *a, const int *ip) { int k; for (k = 0; k < ip[2]; ++k) { a[k] = (k+11)/(k+2); } } ---------- example 2 ---------- test2(int *a) { int k, ip[4]; vbar(ip, 4, 7); for (k = 0; k < ip[2]; ++k) { a[k] = (k+11)/(k+2); } } However, in both cases the trip count is the same and equally undecidable, since "vbar()" is an external function. Note that in each example that is the only code in the file and I am running my pa...

...ry to get VGA passthrough working in a Windows 7 x64 domU. I''m running debian squeeze/testing/unstable with Jeremy''s 2.6.32.x kernel. The best I got to work is the device showing up under Windows 7, with all resources and whatnot. I''ve applied the vga-loadbios patch and vBAR-pBAR patch to xen, and the vBAR-pBAR patch to qemu-dm. This behaviour isn''t stable though. Sometimes I can log on and then domU crashes with a BSoD (nvlddmkm.sys). Sometimes I can log on and actually do something. But certain operations, like changing display options or checking devic...

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

There was an inquiry on this list recently about plotting some simple error bars on a graph. Now Splus has a function (error.bar --- originally written by Sue Clancy of DMS, CSIRO, I believe) to do this job virtually at the touch of a key. (Well a few keys. :-) ) The error.bar function is written completely in raw S --- no calls to ``.Internal'' or anything like that. So it would be

I am happy to announce that I have successfully (and finally!) been able to pass a PCIe graphics card via VT-d to a Windows XP HVM DomU. About time!

Hi everyone, First post, already a call for help :) I''m trying to use a gtx 580 with Xen 4 VGA Passthrough to test CUDA performances, the MB is an Asus P7P55 LX with a i7 870, VT-D is enabled in bios and reported as active by Xen. I''m using Debian Squeeze as Dom0 and DomU OS. Dom0 is configured with iommu=1 and iommu=verbose parameters and xen-pciback.hide=(01:00.0)(01:00.1)

This patch supports basic gfx passthrough on QEMU: - disable emulated VGA adpater if there is passthroughed gfx - register/unregister legacy VGA I/O ports and MMIOs for passthroughed gfx Signed-off-by: Ben Lin <ben.y.lin@intel.com> Signed-off-by: Weidong Han <weidong.han@intel.com> _______________________________________________ Xen-devel mailing list

I just wanted to drop a note to say that I have managed to get VGA passthrough working with multiple cards and domUs. The cards I am using are quasi Quadro 5000 (modified GTX470) and quasi Quadro 6000 (modified GTX480). (Here is an older article about modified GTS450 modified to Quadro 2000 if anyone is interested:

Hi List, many People seem to be interested in the Graphic-Card Passthrough Feature (for more or less obvious reasons). Official Support is still under development, and i hope not to interfere with it in any (bad) way ... But i remember my own painfull and timeconsuming research when i wanted this feature to work, so i thought perhaps this spares some time for the unpatient users like me :)

Dear Gordan, I have a Gigabyte Geforce GTX 560. Is it possible to mod it into a Quadro? If it is possible, please give me the link with the list of steps to mod it into a Quadro. Is it a simple process? Thank you very much. -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Dear Xen Users, I have _partial_ (that is, less than 100%) success following Jean David Techer''s Xen 4.2-unstable VGA Passthrough Documentation. In both Windows 8 Consumer Preview HVM and Windows XP Home Edition HVM, I get yellow exclamation mark besides NVIDIA Geforce 8400 GS in Device Manager. NVIDIA Geforce 8400 GS in Device Manager reports: 1) Windows has stopped this device

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.
