LinuxLists.cc - [PATCH v4 1/2] devcoredump: Add dev_coredumpm

2024-06-07 19:32:47

Subject: [PATCH v4 1/2] devcoredump: Add dev_coredumpm_timeout()

Add function to set a custom coredump timeout.

For Xe driver usage, current 5 minutes timeout may be too short for
users to search and understand what needs to be done to capture
coredump to report bugs.

We have plans to automate(distribute a udev script) it but at the end
will be up to distros and users to pack it so having a option to
increase the timeout is a safer option.

v2:
- replace dev_coredump_timeout_set() by dev_coredumpm_timeout() (Mukesh)

v3:
- make dev_coredumpm() static inline (Johannes)

Subject: [PATCH v4 2/2] drm/xe: Increase devcoredump timeout

5 minutes is too short for a regular user to search and understand
what he needs to do to report capture devcoredump and report a bug to
us, so here increasing this timeout to 1 hour.
