* ddb: add ability to print user registersmhorne2021-01-081-1/+23
| | | | | | | | | | | | | | | | | | | | The debugger is always entered after some kind of kernel trap, often a breakpoint in kdb_enter(). This means that the most recent trapframe will include kernel state at the time of the trap, when often it is desirable to the developer to view the contents of the previous trapframe. This trapframe often corresponds to the entry from userspace. The ddb(4) man page claims the ability to display user register state via the 'u' modifier to `show registers`, but this appears untrue. It is not obvious from a quick search of the history when this feature was added, or when it was removed. (Re)implement this feature in db_show_regs, noting that it is not necessarily populated with userspace state.

* Various changes to the registers displayed in DDB for x86.John Baldwin2015-07-221-1/+2
| | | | | | | | | | | | | | | | | | | - Fix segment registers to only display the low 16 bits. - Remove unused handlers and entries for the debug registers. - Display xcr0 (if valid) in 'show sysregs'. - Add '0x' prefix to MSR values to match other values in 'show sysregs'. - MFamd64: Display various MSRs in 'show sysregs'. - Add a 'show dbregs' to display the value of debug registers. - Dynamically size the column width for register values to properly align columns on 64-bit platforms. - Display %gs for i386 in 'show registers'.

* ddb: finish converting boolean values.Pedro F. Giffuni2015-05-211-1/+1
| | | | | | | | | | | | The replacement started at r283088 was necessarily incomplete without replacing boolean_t with bool.

* Mega update for the KDB framework: turn DDB into a KDB backend.Marcel Moolenaar2004-07-101-19/+19
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time. Notes: svn path=/head/; revision=36735
* Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.Poul-Henning Kamp1998-05-281-27/+1
| | | | | | | | | | | | | | | | | | | | | | | Clean up (or if antipodic: down) some of the msgbuf stuff. Use an inline function rather than a macro for timecounter delta. Maintain process "on-cpu" time as 64 bits of microseconds to avoid needless second rollover overhead. Avoid calling microuptime the second time in mi_switch() if we do not pass through _idle in cpu_switch() This should reduce our context-switch overhead a bit, in particular on pre-P5 and SMP systems.
