linux-kselftest-next-6.2-rc1
This Kselftest update for Linux 6.2-rc1 consists of several fixes
and enhancements to existing tests and a few new tests:
- adds new amd-pstate and fixes and enhances existing ones
- adds new watchdog tests and enhances existing ones to improve coverage
- fixes to ftrace, splice_read, rtc, and efivars tests
- fixes to handle egrep obsolescence in the latest grep release
- miscellaneous spelling and SPDX fixes

2). Tbench test
|
||||
|
||||
Test and monitor the cpu changes when running tbench benchmark under the specified governor.
|
||||
These changes include desire performance, frequency, load, performance, energy etc.
|
||||
The specified governor is ondemand or schedutil.
|
||||
Tbench can also be tested on the ``acpi-cpufreq`` kernel driver for comparison.
|
||||
|
||||
3). Gitsource test
|
||||
|
||||
Test and monitor the cpu changes when running gitsource benchmark under the specified governor.
|
||||
These changes include desire performance, frequency, load, time, energy etc.
|
||||
The specified governor is ondemand or schedutil.
|
||||
Gitsource can also be tested on the ``acpi-cpufreq`` kernel driver for comparison.
