https://bugzilla.suse.com/show_bug.cgi?id=1218153 Bug ID: 1218153 Summary: reduce SERIAL_8250_RUNTIME_UARTS? Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: lnussel@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- CONFIG_SERIAL_8250_RUNTIME_UARTS is currently set to 32 which leads to 32 /dev/ttyS*. The upstream default is 4. Is there a need to pre-create that many nodes? I noticed that it clutters the `systemd-analyze blame` quite a bit when looking for boot times. Maybe reduce it back to 4? Users that really need that many ports can set 8250.nr_uarts=32 on the kernel command line as documented upstream: https://github.com/torvalds/linux/blob/master/drivers/tty/serial/8250/Kconfi... -- You are receiving this mail because: You are the assignee for the bug.
