2024-10-10scripts/gdb: fix timerlist parsing issueKuan-Ying Lee
commit a633a4b8001a7f2a12584f267a3280990d9ababa upstream. Patch series "Fix some GDB command error and add some GDB commands", v3. Fix some GDB command errors and add some useful GDB commands. This patch (of 5): Commit 7988e5ae2be7 ("tick: Split nohz and highres features from nohz_mode") and commit 7988e5ae2be7 ("tick: Split nohz and highres features from nohz_mode") move 'tick_stopped' and 'nohz_mode' to flags field which will break the gdb lx-mounts command: (gdb) lx-timerlist Python Exception <class 'gdb.error'>: There is no member named nohz_mode. Error occurred in Python: There is no member named nohz_mode. (gdb) lx-timerlist Python Exception <class 'gdb.error'>: There is no member named tick_stopped. Error occurred in Python: There is no member named tick_stopped. We move 'tick_stopped' and 'nohz_mode' to flags field instead.

2023-04-18scripts/gdb: fix lx-timerlist for HRTIMER_MAX_CLOCK_BASES printingPeng Liu
HRTIMER_MAX_CLOCK_BASES is of enum type hrtimer_base_type. To print it as an integer, HRTIMER_MAX_CLOCK_BASES should be converted first.

2023-04-18scripts/gdb: fix lx-timerlist for Python3Peng Liu
Below incompatibilities between Python2 and Python3 made lx-timerlist fail to run under Python3. o xrange() is replaced by range() in Python3 o bytes and str are different types in Python3 o the return value of Inferior.read_memory() is memoryview object in Python3 akpm: cc stable so that older kernels are properly debuggable under newer Python.

2023-04-18scripts/gdb: fix lx-timerlist for struct timequeue_head changePeng Liu
commit 511885d7061e ("lib/timerqueue: Rely on rbtree semantics for next timer") changed struct timerqueue_head, and so print_active_timers() should be changed accordingly with its way to interpret the structure.

2019-05-14scripts/gdb: add a timer list commandStephen Boyd
Implement a command to print the timer list, much like how /proc/timer_list is implemented. This can be used to look at the pending timers on a crashed system.
