2024-09-01scripts/gdb: fix timerlist parsing issueKuan-Ying Lee1-15/+16
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: timerlist: convert int chunks to strAmjad Ouled-Ameur1-1/+1
join() expects strings but integers are given.

2023-04-18scripts/gdb: fix lx-timerlist for HRTIMER_MAX_CLOCK_BASES printingPeng Liu1-1/+2
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 Liu1-1/+3
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 Liu1-2/+1
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 Boyd1-0/+219
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.
