CTF generation
Hello everybody!
How do people generate the Compact Type Format (CTF) section?
Do you have a special parser or employ gcc debug information?
Is there any open utility to do this job?
Best regards,

RFC: XRay in the LLVM Library
Hi Dean,
I haven't looked very closely at XRay so far, but I'm wondering if making CTF (common trace format, e.g. see http://diamon.org/ctf/) the default format for XRay traces would be useful?
It seems it'd be nice to be able to reuse some of the tools that already exist for CTF, such as a graphical viewer (http://tracecompass.org/) or a converter library (http://man7.org/linux/...

where do kernel data types come from?
I have a script where I can freely reference struct nameidata*, struct
vnode*, etc. on Snow Leopard.
How does DTrace know about these data types? I understand things like
#pragma D depends_on library darwin.d
where darwin.d has typedefs.
I can''t find definitions of nameidata and vnode in any D scripts,
though. How does it work?
Thanks, Joel

DTrace merged ready for 7.1
...ll, either the dog ate it or subversion decided that it was
for certain eyes only (and not yours, or mine).
I have added a note to src/UPDATING mentioning this and a link to the
documentation.
I want 7.1 release to be built with a GENERIC kernel containing not only the DTrace
hooks, but also the CTF data, so I have defaulted the 'make buildkernel' to
turn on CTF generation. If you are building a kernel and modules without the
KDTRACE_HOOKS option, then you should do a 'make WITHOUT_CTF=1 buildkernel' to
avoid generating the CTF data (although that won't hurt).
For all buil...

RFC: XRay in the LLVM Library
Hi llvm-dev,
Recently, we've committed the beginnings of the llvm-xray [0] tool which allows for conveniently working with both XRay-instrumented libraries as well as XRay trace/log files. In the course of the review for the conversion tool [1] which turns a binary/raw XRay log file into YAML for human consumption purposes, a question arose as to how we intend to allow users to develop tools

ERROR: ctfmerge: Cannot open output file isp for r/w: No such fil
OK, I am trying to dtrace isp(4) module in freebsd 7.
each obj file is converted using:
ctfconvert -L VERSION isp_freebsd.o
and using "ctfdump isp_freebsd.o" I can see CTF info embedded in the .o file
but in the linked kernel module, I found much less CTF info inside it.
I guess I should use "ctfmerge" to combine the CTF info from each obj file into the final kernel...

MySQL THD via PID Provider
I want to go a lot deeper with my tracing of MySQL and to do so I want to look into MySQL Thread Descriptors (class THD). Inside is a great bulk of information utilized by a great many of the core functions within MySQL... I really want to get in there.
So far I''ve had no luck though. It''s a C++ class, and I''m afraid that I''m approaching it like a C struct,

Using DTrace in 32-bit to handle 64-bit parameters [72631230]
Hi all,
OK, so this at first looked like a clear cut "Don''t do it, or at worst
handle the results" issue my customer has come to me with, but the more
we discuss it, the more it looks like we should have better ways of
dealing with this issue.

dtrace missing ''unlinkat''? showing process stack?
everyone,
Just out of curiosity, I did a
dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }''
and looked at the entries produced by ''rm''.
I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files.
So - does dtrace contain unlinkat as a probe for a system call?

Sidebar to Systemtap and Dtrace Comparison
My leaky memory says we moved entry-point
into some form of debug record in the
standard libraries, circa Solaris 8/9.
Before that, my group maintained text files that
listed all the entry-points and their parameters for
libraries like libc.so, so that we could print
out parameter values in apptrace(8).
There''s a (small) chance the records are complete enough
that dtrace could use the

Enable anonymous tracing make Sunw2100z hang during boot

dtrace''ing at module unload time
Hi,
I am trying to trace some functions that are executed at detach time, and it seems that just
having dtrace around to instrument the module is causing a short circuit, whereas modunload will
return (device busy). I understand that this makes sense, but how can I get around this if I
want to trace stuff at detach time?
Thanks,

How to print kernel global variable.
I am doing some testing on the adjtime syscall, and I want to
dump out the value of the kernel variable "timedelta", and I
am failing at it. Some of my attempts got "Module is no longer
loaded" and some got "Symbol table entry is not a data object"
I found some info that dtrace can print out kernel global
variable, so what am I missing here?

RFC: Loadable segments watermark for lld
The ELF file header isn't always covered by a segment but still affects
loading. I think everything else that effects loading/dynamic linking is
always covered by a PT_LOAD segment. As evidence this is basically what
--strip-sections in llvm-strip and eu-strip do and they produce perfectly
runnable binaries.
Having a hash of the actual memory map is interesting IMO. Build IDs can't

Help with booting dom0 on a Dell 2950
Hi, I have installed b_78 on a Dell 2950 and booting to bare metal works fine but when I try to boot using the grub entry Solaris xVM it will boot to the point where it displays the uname info and then just stays there. It will not boot past that point. I have enabled VT technology in the BIOS (but only after the installation).
