Implement functions calls from within DDB on ia64. On ia64 a function pointer doesn't point to the first instruction of that function, but rather to a descriptor. The descriptor has the address of the first instruction, as well as the value of the global pointer. The symbol table doesn't know anything about descriptors, so if you lookup the name of a function you get the address of the first instruction. The cast from the address, which is the result of the symbol lookup, to a function pointer as is done in db_fncall is therefore invalid. Abstract this detail behind the DB_CALL macro. By default DB_CALL is defined as db_fncall_generic, which yields the old behaviour. On ia64 the macro is defined as db_fncall_ia64, in which a descriptor is constructed to yield a valid function pointer. While here, introduce DB_MAXARGS. DB_MAXARGS replaces the existing (local) MAXARGS. The DB_MAXARGS macro can be defined by platforms to create a convenient maximum. By default this will be the legacy 10. On ia64 we define this macro to be 8, for 8 is the maximum number of arguments that can be passed in registers. This avoids having to implement spilling of arguments on the memory stack.

Support statically attaching of ddb commands in non-ddb modules. The details are hidden in the DB_COMMAND(cmd_name, func_name) and DB_SHOW_COMMAND(cmd_name, func_name) macros. DB_COMMAND() adds to the top-level ddb command table and DB_SHOW_COMMAND adds to the `show' subtable. Most external commands will probably be `show' commands with no side effects. They should check their pointer args more carefully than `show map' :-), or ddb should trap internal faults better (like it does for memory accesses). The vm ddb commands are temporarily unattached. ddb.h: Also declare `db_indent' and db_iprintf() which will replace vm's `indent' and iprintf().

#define DB_COMMAND(cmd_name, func_name) \
Clean up the way we handle auxiliary commands for a given ddb command table. Previously, the ddb code knew of each linker set of auxiliary commands and which explicit command list they were tied to. These changes add a simple command_table struct that contains both the static list of commands and the pointers for any auxiliary linker set of additional commands. This also makes it possible for other arbitrary command tables to be defined in other parts of the kernel w/o having to edit ddb itself. The DB_SET macro has also been trimmed down to just creating an entry in a linker set. A new DB_FUNC macro does what the old DB_SET did which is to not only add an entry to the linker set but also to include a function prototype for the function being added. With these changes, it's now also possible to create aliases for ddb functions using DB_SET() directly if desired.

- Change the ddb paging "support" to use a variable (db_lines_per_page) to control the number of lines per page rather than a constant. The variable can be examined and changed in ddb as '$lines'. Setting the variable to 0 will effectively turn off paging. - Change db_putchar() to force out pending whitespace before outputting newlines and carriage returns so that one can rub out content on the current line via '\r \r' type strings. - Change the simple pager to rub out the --More-- prompt explicitly when the routine exits. - Add some aliases to the simple pager to make it more compatible with more(1): 'e' and 'j' do a single line. 'd' does half a page, and 'f' does a full page. MFC after: 1 month Inspired by: kris

Mega update for the KDB framework: turn DDB into a KDB backend. Most of the changes are a direct result of adding thread awareness. Typically, DDB_REGS is gone. All registers are taken from the trapframe and backtraces use the PCB based contexts. DDB_REGS was defined to be a trapframe on all platforms anyway. Thread awareness introduces the following new commands: thread X switch to thread X (where X is the TID), show threads list all threads. The backtrace code has been made more flexible so that one can create backtraces for any thread by giving the thread ID as an argument to trace. With this change, ia64 has support for breakpoints.

Add two helper functions: db_lookup_thread() and db_lookup_proc(). They take the addr value passed to a ddb command and attempt to use it to lookup a struct thread * or struct proc *, respectively. Each function first reparses the passed in value as if it was an ID entered in base 10. For threads the ID is treated as a thread ID, for proceses the ID is treated as a PID. If a thread or proc matching the ID is found, it is returned. For db_lookup_thread(), if the check_pid argument is true and it didn't find a thread with a matching thread ID, it will treat the ID as a PID and look for a matching process. If it finds one it returns the first thread in the process. If none of the ID lookups succeeded, then the functions assume that the passed in address is a thread or proc pointer, respectively. This allows one to use tids, pids, or structure pointers interchangeably in ddb functions that want to lookup threads or processes if desired.

Add 'hwatch' and 'dhwatch' ddb commands analogous to 'watch' and 'dwatch'. The new commands install hardware watchpoints if supported by the architecture and if there are enough registers to cover the desired memory area. No objection by: audit@, hackers@ MFC after: 2 weeks

Mega update for the KDB framework: turn DDB into a KDB backend. Most of the changes are a direct result of adding thread awareness. Typically, DDB_REGS is gone. All registers are taken from the trapframe and backtraces use the PCB based contexts. DDB_REGS was defined to be a trapframe on all platforms anyway. Thread awareness introduces the following new commands: thread X switch to thread X (where X is the TID), show threads list all threads. The backtrace code has been made more flexible so that one can create backtraces for any thread by giving the thread ID as an argument to trace. With this change, ia64 has support for breakpoints.

Add a one-shot callout facility to db_printf() that executes the registered callout when a specified number of lines have been output. This can be used to implement pagers for ddb commands that output a lot of text. A simple paging function is included that automatically rearms itself when fired. Reviewed by: bde, julian

Support statically attaching of ddb commands in non-ddb modules. The details are hidden in the DB_COMMAND(cmd_name, func_name) and DB_SHOW_COMMAND(cmd_name, func_name) macros. DB_COMMAND() adds to the top-level ddb command table and DB_SHOW_COMMAND adds to the `show' subtable. Most external commands will probably be `show' commands with no side effects. They should check their pointer args more carefully than `show map' :-), or ddb should trap internal faults better (like it does for memory accesses). The vm ddb commands are temporarily unattached. ddb.h: Also declare `db_indent' and db_iprintf() which will replace vm's `indent' and iprintf().

/*
* Command table.
*/
Clean up the way we handle auxiliary commands for a given ddb command table. Previously, the ddb code knew of each linker set of auxiliary commands and which explicit command list they were tied to. These changes add a simple command_table struct that contains both the static list of commands and the pointers for any auxiliary linker set of additional commands. This also makes it possible for other arbitrary command tables to be defined in other parts of the kernel w/o having to edit ddb itself. The DB_SET macro has also been trimmed down to just creating an entry in a linker set. A new DB_FUNC macro does what the old DB_SET did which is to not only add an entry to the linker set but also to include a function prototype for the function being added. With these changes, it's now also possible to create aliases for ddb functions using DB_SET() directly if desired.
