This 4th version of the scale invariance patchset adds an important change
compare to previous ones. It still scales the time to reflect the
amount of work that has been done during the elapsed running time but this is
now done at rq level instead of per entity and rt/dl/cfs_rq. The main
advantage
Move rq_of() helper function so it can be used in pelt.c

The current implementation of load tracking invariance scales the
contribution with current frequency and uarch performance (only for
utilization) of the CPU. One main result of this formula is that the
figures are capped by current capacity of CPU. Another one is that the

Hi all,
This series adds platform support for AAEON's UP Squared, a x86 SBC
based on Apollo Lake [1]. Specifically, it enables control for the board
pin headers and for the LEDs, as both of these features are only

Add a serial driver for the SiFive UART, found on SiFive FU540 devices
(among others).
The underlying serial IP block is relatively basic, and currently does
not support serial break detection. Further information on the IP
block can be found in the documentation and Chisel sources:
