| | | | | | | | | | | | | | | ABI change on ILP32 platforms and relating to events. However it's harmless on little-endian ILP32 platforms in the sense that it doesn't cause breakages. Old ILP32 thread libraries write a 32-bit th_p and new thread libraries write a 64-bit th_p. But due to the fact that we have an unused 32-bit data field right after th_p and that field is always initialized to zero, little-endian ILP32 machines effectively have a valid 64-bit th_p by accident. Likewise for new thread libraries and old libthread_db: little endian ILP32 is unaffected. At this time we don't support big-endian threaded applications in GDB, so the breakage for the ILP32 case goes unnoticed.

* - Change how the vmcore target maps FreeBSD thread IDs to GDB ptids. Wejhb2008-05-018-47/+40
| | | | | | | | | | | | | | now only use the TID and ignore the PID and use pid_to_ptid() to build a ptid treating the TID as a PID. The benefit of this is that the vmcore target now uses the same scheme as GDB's remote targets. As a result, the 'tid' command now works for remote targets (however, it only accepts TIDs and not addresses of 'struct thread' objects). - Use gdb_thread_select() to do the actual thread switch for the 'tid' and 'proc' commands. This now gives the same UI feedback when switching threads as the GDB 'thread' command rather than providing no visual output at all. MFC after: 1 week
* Rework how kgdb manages kernel and vmcore files to be a bit more gdb-ishjhb2008-04-2911-184/+338
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | so that kgdb can be used more like a normal gdb: - Load the kernel via the standard 'exec' target and allow it to be changed via the 'file' command. - Instead of explicitly loading the kernel file as the mail symbol file during startup, just pass it to gdb_main() as the executable file. - Change the kld support (via shared libraries) to cache the address of the linker_files and linker_kernel_file variables in addition to the offsets of various members in 'struct linker_file'. - When a new symbol file is loaded, recompute the addresses and offsets used by the kld support code. - When a new symbol file is loaded, recalculate the ofs_fix variable to account for the different ways a trapframe can be passed to trap frame handlers in i386. This is done by adding a MD kgdb_trgt_new_objfile() hook that is empty on all but i386. - Don't use the directory name of the kernel specified on the command line to find kernel modules in the kld support code. Instead, extract the filename of the current executable via exec_bfd. Now the 'kernel' variable is private to main.c again. - Make the 'add-kld' command explicitly fail if no executable is loaded. - Make the support for vmcores a real core-dump target that opens the kernel and vmcore on open and closes the kvm connection when closed, etc. - The 'core' command can now be used to select a vmcore to use, either a crash dump file or /dev/mem for live debugging. - The 'detach' command can be used to detach from a vmcore w/o attaching to a new one. - kgdb no longer explicitly opens a core dump during startup and no longer has to use an atexit() hook to close the kvm connection on shutdown. - Symbols for kld's are automatically loaded anytime a core is opened. Also, the unread portion of dmesg is dumped just as it was done on kgdb startup previously. - Don't require either a remote target or core dump if a kernel is specified. You can now just run 'kgdb kernel' similar to running gdb on an executable and later connect to a remote target or core dump. - Use a more relaxed way to verify remote targets specified via -r. Instead of explicitly allowing a few non-file target specifications, just assume that if stat() on the arg and on "/dev/" + arg both fail that is some non-file target and pass it to gdb. - Don't use a custom interpreter. The existing kgdb_init() hook and the target_new_objfile() hook give us sufficient hooks during startup to setup kgdb-specific behavior now. - Always add the 'proc', 'tid', and 'add-kld' commands on startup and not just if we have a core dump. Currently the 'proc' and 'tid' commands do not work for remote targets (I will fix at least 'tid' in the next round of changes though). However, the 'add-kld' command works fine for loading symbols for a kernel module on a remote target. - Always setup the 'kld' shared library target operations instead of just if we have a core dump. Although symbols for kernel modules are not automatically loaded when connecting to a remote target, you can do 'info sharedlibrary' after connecting to the remote target and kgdb will find all the modules. You can then use the 'sharedlibrary' command to load symbols from the module files. - Change kthr_init() to free the existing list of kthr objects before generating a new one. This allows it to be invoked multiple times w/o leaking memory. MFC after: 1 week

| | | | | | | | | | | | | | force the FreeBSD multithreaded core target to not register any target for handling core dumps. This is analogous to the 'coreops_suppress_target' variable that GDB provides for suppressing the default core dump target. KGDB will use this new variable so it can provide its own core dump target that uses libkvm to work with vmcore files. - Adjust the long name and documentation of the FreeBSD multithreaded core dump target so it better matches what GDB's core dump target uses.

* - Rework the kld support to hook into GDB's shared library support.jhb2008-01-293-81/+165
| | | | | | | | | | | | | | | kgdb(8) now treats kld's as shared libraries relative to the kernel "binary". Thus, you can use 'info sharedlibrary' to list the kld's along with 'sharedlibrary' and 'nosharedlibrary' to manage symbol loading and unloading. Note that there isn't an easy way to force GDB to use a specific path for a shared library. However, you can use 'nosharedlibrary' to unload all the klds and then use 'sharedlibrary' to load specific klds where it gets the kld correct and use 'add-kld' for the kld's where the default open behavior doesn't work. klds opened via 'sharedlibrary' (and during startup) do have their sections listed in 'info files'. - Change the 'add-kld' command to use filename completion to complete its argument.
