Folks, We came across a memory race condition between VPP vhost driver and the kernel vhost. VPP is running a tap interface over vhost backend. In this case, VPP is acting as the vhost driver mode and the kernel vhost is acting as the vhost device mode. In the kernel vhost?s TX traffic direction which is VPP?s RX traffic direction, kernel vhost is the producer and VPP is the consumer. Kernel

Hello, I'm experiencing a kernel panic that appears to be caused by zfs. No errors are making it into /var/log/messages, but here is the error message that appears on my screen after panic (transcribed): panic solaris assert BSWAP_32(sa_hdr_phys->sa_magic) == SA_MAGIC, file: /src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/sa.c, line 1262 I can reproduce this by

Is it possible to use DTrace to display the number of arguments and their types for userland or kernel functions that are not explicitly instrumented or documented by their authors? We''re talking about functions provided by Veritas VxVM/VxFS and the like, and for example, we might want to try tracing I/Os from App => VxFS => VxVM => ssd driver to see where I/Os get aggregated or

Hi, Since almost all operations in the FUSE low-level API identify files by inode number, I''ve been using zfs_zget() to get the corresponding znode/vnode in order to call the corresponding VFS function in zfs_vnops.c. However, there are some cases when zfs_zget() behaves slightly different than I need: 1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return

Anyone have problems with getaddrinfo under AIX4.3? I have built 2.5.0 under linux, HP and VPP without too much in the way of problems. However, AIX4.3 version builds OK but doesn't execute getaddrinfo correctly. Any ideas?

The current code for primitive splitting and emission on pre-nv50 is severely broken. In particular: 1. Quads and lines are totally broken because "&= 3" should be "&= ~3" and similar for lines 2. Triangle fans and polygons are broken because the first vertex must be repeated for each split chunk 3. Line loops are broken because the must be converted to a line strip,

OK, I''ve been fritzing around with something I noticed last night, thinking that I understood what was going on, but now it''s getting confusing again. A system that has been running for a couple of months had a hole in the probe ID list near the end in the middle of the fbt probes. And then a couple of syscall probes were stuck in the hole. It looked like this: ... 40311

A few days ago I loaded R version 1.4.1 to run on Windows 98 and haven't been able to find information on the GUI approach in the FAQs, R Reference Index, or Search Engine . Edit has an item that allows changing GUI preferences, and the Target path in the icon ends in Rgui.exe, so it appears that R for Windows does include using the GUI approach. In S-Plus I wrote a application with

Hello! I want to do a non-linear regression with 2 explanatory variables (something like : length ~ a * time * exp( b* temperature)), having a data set (length, time, temperature). Which function could I use (I tried nls but I think it doesn't work) Thanks a lot! Janice

Unfortunately that's not really an R question. I recommend that you read up on the statistical methods underneath. One that I'd wholeheartedly recommend is Prof. Harrell's `Regression Modeling Strategies'. [BTW, there are now two implementations of gam() in R: one in `mgcv', which is fairly different from that in `gam'. I'm guessing you're referring to the one

I''m using a fbt probe where I get a system call id as an argument, how do I look up the name of it? At the moment I''m post-processing the output using /etc/name/to_sysnum but that doesn''t feel right :) cheers, /Martin -- This message posted from opensolaris.org

If I use a simple dtrace script such as this: fbt::somefunc:entry{self->trace=1;} fbt::somefunc:return{self->trace=0;} fbt:::entry{} fbt:::return{printf("%lx", arg1);} then it will descend to whatever depth is necessary If I want to limit it to say 3 functions deep, how can I do that? The quick answer I want to use is to do "self->depth++" on each entry and then

Hi all, I have questions about something I observed just now: 1) on AMD64, S10u1: # dtrace -n ''fbt::copystr:entry{printf ("%p\n", args[0]);}'' -c /bin/pwd dtrace: invalid probe specifier fbt::copystr:entry{printf ("%p\n", args[0]);}: in action list: index 0 is out of range for fbt::copystr:entry args[ ] but # dtrace -n ''fbt::copystr:entry{printf

Hey all, In order to make sure SIG content is "fresh", whenever a new version of CentOS comes out, content is discarded automatically unless SIG chairs specifically request it to be moved over. At the moment, Xen has three repos that are under consideration to be moved up: virt/x86_64/xen-46 virt/x86_64/xen-48 virt/x86_64/xen-410 I'll request xen-48 and xen-410 to be updated for

what is differenct between syscall::write:entry fbt::write:entry are the two probe fires at the same place. -- This message posted from opensolaris.org

Whilst trying out some D to get an insight into what is the most common reason for a given function to return, I have bumped into an error I don''t understand. The first take on what I was trying to do was: # dtrace -n ''fbt:ip:ip_input:return{@home[arg0] = count();}'' and all was well. The next step was: # dtrace -n
