[Crash-utility] Re: Bug report: "timer -r" option fails on 6.18-rc kernels

This is due to [1]. [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit...

The "timer -r" option displays the base->get_time function, but now kernel switches the function by base->clockid, which are CLOCK_* macro values. We can copy the function names and macro values from the kernel, but if they are modified, crash cannot follow the changes automatically. How should we fix this? or in the first place, maybe we can change what the "timer -r" displays there, instead of .get_time function name. For example, if we show enum hrtimer_base_type values by base->index: crash> timer -r CPU: 0 HRTIMER_CPU_BASE: ffff8b7aefc20640 CLOCK: 0 HRTIMER_CLOCK_BASE: ffff8b7aefc20680 [HRTIMER_BASE_MONOTONIC] ... CLOCK: 1 HRTIMER_CLOCK_BASE: ffff8b7aefc206c0 [HRTIMER_BASE_REALTIME] ... What do you think?

Thanks, Kazu
