* configure.ac: Add a warning about known bugs in the kernel
-
Requirements:
- A Linux kernel version 2.6.11 or newer is required.
- GTK+ 2.6.0 or newer is required
-- libglade 2.5.1 is required
+- libglade 2.5.1 or newer is required
Compiling:
system compiler, but if you have upgraded your kernel it is
possible that the new kernel was compiled with a different compiler
- In that case, "modprobe sysprof-module" will produce this
+ If the module is compiled with a different compiler than the one
+ compiling the kernel, "modprobe sysprof-module" will produce this
error message:
insmod: error inserting './sysprof-module.o': -1 Invalid module format
-
Debugging symbols
-- The programs you want to profile should have debugging symbols, or
- you won't get much usable information. On a Fedora Core system,
- installing the relevant -debuginfo package should be sufficient.

+- The programs and libraries you want to profile should have debugging
+ symbols, or you won't get much usable information. On a Fedora Core system,
+ installing the relevant <package>-debuginfo package should be sufficient.
+ On Ubuntu and Debian, the debug packages are called <package>-dbg.
-- X server.
+- X server
The X server as shipped by most distributions uses its own home-rolled
module loading system and Sysprof has no way to deal with that, so if you
- run sysprof with your normal X serverr you won't get any information about
+ run sysprof with your normal X server you won't get any information about
how time is spent inside the X server.
- To fix this you have to compile your own X server:
+ On Ubuntu and Debian there is a package, xserver-xorg-dbg, containing a
+ binary called Xorg-debug that is built in such a way that sysprof can use
+ it. On other systems, to get an X server with usable symbols you
+ have to compile your own:
(1) Compile the X server to use ".so" modules:
xc/config/cf/xorgsite.def.
If you are compiling the CVS version of the X server
- (the one that will eventually become 7.0), then this is

already the default.
- "make World"
+
+ - Don't run "make install" yet. (See below).
- (2) Install the X server making sure it can't see any ".a" files. If
- you install on top of an existing installation, just do
+ (2) Make sure the new X server can't see any old ".a" files lying
+ around. If you install on top of an existing installation, just do
find /usr/X11R6/lib/"*.a" | sudo xargs rm
- and install the newly compiled X server.
+ then run "make install" as root to install the newly compiled
+ X server.
If a ".so" X server finds .a files in its module path it will
try to load those in preference to .so files and this causes
This is just the (deleted) problem.
* Build system
- - Find out what distributions it actually works on
- (ask for sucess/failure-stories in 1.0 releases)
-
- Create RPM package? See fedora-packaging-list for information
about how to package kernel modules. Lots of threads in
June 2005 and forward.
Before 1.2:
+* Crash reported by Rudi Chiarito with n_addrs == 0.
+
+* Find out why we get hangs with rawhide kernels. This only happens with the
+ 'trace "current"' code. See this mail:
+
+ http://mail.nl.linux.org/kernelnewbies/2005-08/msg00157.html
+
+ esp0 points to top of kernel stack
+ esp points to top of user stack
+
+ (Reported by Kjartan Marass).
+
* Figure out how to make sfile.[ch] use less memory.
- In general clean sfile.[ch] up a little:
- split out dfa in its own generic class
DONE:
-Before 1.0:
+* Find out what distributions it actually works on
+ (ask for sucess/failure-stories in 1.0 releases)
+
+* Add note in README about Ubuntu and Debian -dbg packages and how to get
+ debug symbols for X there.
+
+* Before 1.0:
- Update version numbers in source
