Subject: [PATCH] realtime: Set tsc as 'reliable'
|
||||
|
||||
We already disable the clocksource watchdog, it's there to double-check
|
||||
whether clock results are coherent between reads. But a new reliability
|
||||
test was introduced in recent kernels[1], tracking tsc drift between
|
||||
CPUs[2]. It works by programming timers on all CPUs, including isolated
|
||||
ones, and checks whether the tsc was adjusted in between runs. This
|
||||
introduces unwarranted latency on real time systems. So let's promote
|
||||
tsc to 'reliable', which disables both checks.
|
||||
|
||||
There shouldn't be any impact on old nor new setups. First, this test
|
||||
didn't exist in the past, so any eventual drift was left uncorrected.
|
||||
Second, most telco and HPC use-cases will make heavy use of tsc in
|
||||
user-space, and its reliability is already assumed in the system's
|
||||
design.
|
||||
|
||||
[1] c7719e793478 x86/tsc: Add a timer to make sure TSC_adjust is always
|
||||
checked
|
||||
[2] Generally caused by rogue BIOSes adjusting the tsc on a CPU and not
|
||||
doing so on the rest
