Since much debugging still centers around processes, having the pid is quite helpful. - Change the ddb paging "support" to use a variable (db_lines_per_page) to 2004-11-01T22:15:15Z John Baldwin jhb@FreeBSD.org 2004-11-01T22:15:15Z urn:sha1:d39d4a6e6412f88225d1b78c8a797ab82daac250 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. 2004-07-10T23:47:20Z Marcel Moolenaar marcel@FreeBSD.org 2004-07-10T23:47:20Z urn:sha1:37224cd3fcb911d440e40dd8e1f31652e2452537 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.
