Somebody else might have better -methods on doing it. This person is therefore invited to share this -experience with the rest of the world by adding it here. - -Paul Flinders has made some patches to gdb to add support for loadable -modules. This version of gdb is currently available as binary for -Linux/x86 on Paul's web site: - - www.dawa.demon.co.uk/xfree-gdb - -This web-site also contains the patches to gdb 4.18 so you may port it -to other platforms. - -It loads the module symbols and supports all gdb features like -breakpointing, disassembling and single stepping. It also shows the -exact location of a signal 11. Paul has fixed the code so that all of -this is working even if using modules compiled without -g. You can -find his latest version on his web site. - -If no module aware gdb is available the following hints might help: - -1. Use remote login. This can be done thru a network connection or - simply by connecting a serial console. This enables you to watch - the Xservers output while running set breakpoints with gdb etc. - Don't even try to run the Xserver from a system console. Whenever - something happens gdb waits for input. However the Xserver has - locked the system console including the keyboard, therefore you'll - never be able to send any input to gdb. Even if your process - doesn't crash or you haven't set any breakpoints a vt switch can be - hazardous: When doing vt switching a signal is sent; unless you did - - gdb> handle SIGUSR1 nostop - - gdb waits for you to continue the program which cannot happen as - you don't have access to gdb's console. - -2. You can compile any source file with debugging symbols to obtain - more information about where an error occurred. Simply go to the - directory which holds the corresponding object file and do: - - # rm .o - # xc/config/util/makeg.sh .o - - After relinking the server or module gdb is able to obtain the - necessary debugging information and will show the exact line in the - source where the error ccurred. See also: - xc/config/util/makeg.man. - -3. In some cases it might be useful to have the assembler output of a - compiled source file. This can be obtained by doing: - - # make .s - - or - - # xc/config/util/makeg.sh .s - - Make will use exactly the same rules it uses for building *.o files. - -4. In some cases it might be useful to set breakpoints in modules. If - no module aware gdb is available you should add a call to one of - the three dummy breakpoint functions - - xf86Break1(), xf86Break2() and xf86Break3() - - to the source file and recompile the module. You now just have to - set a breakpoint onto the appropriate dummy functions. These - functions are located in the core part of the server and therefore - will be available any time. - -5. Without module support gdb is not able to print the function where - an error occurred in a module. - - If you get a line like: - - (gdb) bt - #0 0x823b4f5 in ?? () - .... - - You may obtain the function the address belongs to by calling - LoaderPrintSymbol(): - - (gdb) call LoaderPrintSymbol(0x823b4f5) - - The symbol returned might not always be the name of the function - which contains the address. In case of static functions the symbol - is not known to the loader. However LoaderPrintSymbol() will print - the nearest known function and the offset from its start. You may - easily find the exact location of the address if you do: - - # objdump --disassemble .o - - .o is the name of the object file containing the symbol printed. - -6. Locating static symbols in modules is simpler if the module is a - single object file instead of a library. Such a object file can - easily be build from a library: # mkdir tmp # cd tmp; ar x - module-path/.a # ld -r *.o -o module-path/.o - - When calling LoaderPrintSymbol() the closes public symbol will be - printed together with the offset from the symbol's address. If a - static symbol comes before the first public symbol in a module The - following trick may help: - - create a file 1-.c in tmp/ - containing: - void Dummy-() {} - - Compile it: - - # gcc -c 1-.c - - and do the link step above. - - This way Dummy-() will be the first public function in the - module. All addresses in static function can now be printed - relatively to this address if no other public function comes before - this static one. - -7. In some situations it is quite helpful to add debugging symbols to - the binary. This can be done per object file. Simply remove the - object file and do - - # makeg - - When looking for a bug in a module these debugging infos can be - very helpful: Calling LoaderPrintSymbol() as described above will - return a function and an offset giving the exact location of the - address with respect to this function entry point. When - disassembling an object file with debugging symbols: # objdump -d - -l .o one will receive a disassembled output containing line - number information. Thus one can locate the exact line of code - where the error occurred. - -8. To quickly trace the value of a variable declared in a module three - dummy variables have been added to the core part: - - CARD32 xf86DummyVar1; - CARD32 xf86DummyVar2; - CARD32 xf86DummyVar3; - - The variable can be assigned to one of them. One can then use gdb - to return the value of this variable: - - gdb> p /x xf86DummyVar1 - -9. Sometimes it might be useful to check how the preprocessor replaced - symbols. One can obtain a preprocessed version of the source file - by doing: - - make .i - - This will generate a preprocessed source in .i. - -10. xfree() can catch if one tries to free a memory range twice. You - will get the message: - - Xalloc error: range already freed in Xrealloc() :-( - - To find the location from which xfree() was called one can - breakpoint on XfreeTrap(). The backtrace should show the origin of the - call this call. - -11. To access mapped physical memory the following functions might be - useful. - - These may be used to access physical memory that was mapped using - the flags VIDMEM_FRAMEBUFFER or VIDMEM_MMIO32: - - CARD8 xf86PeekFb8(CARD8 *p); - CARD16 xf86PeekFb16(CARD16 *p); - CARD32 xf86PeekFb32(CARD32 *p); - void xf86PokeFb8(CARD8 *p, CARD8 v); - void xf86PokeFb16(CARD16 *p, CARD16 v); - void xf86PokeFb32(CARD16 *p, CARD32 v); - - Physical memory which was mapped by setting VIDMEM_MMIO should be - accessed using the following. Here the base address to which the - memory is mapped and the offset are required separately. - - CARD8 xf86PeekMmio8(pointer Base, unsigned long Offset); - CARD16 xf86PeekMmio16(pointer Base, unsigned long Offset); - CARD32 xf86PeekMmio32(pointer Base, unsigned long Offset); - void xf86PokeMmio8(pointer Base, unsigned long Offset, CARD8 v); - void xf86PokeMmio16(pointer Base, unsigned long Offset, CARD16 v); - void xf86PokeMmio32(pointer Base, unsigned long Offset, CARD32 v); - diff --git a/xorg-server/hw/xfree86/doc/devel/Makefile.am b/xorg-server/hw/xfree86/doc/devel/Makefile.am index
