Hello,
CPPC cpufreq driver is used for ARM servers and this patch series tries
to provide counter-based frequency invariance support for them in the
absence for architecture specific counters (like AMUs).
This is tested by:
- /me with some hacks on Hikey, as I didn't have access to the right
ha
This patch attempts to make it generic enough so other parts of the
kernel can also provide their own implementation of scale_freq_tick()
callback, which is called by the scheduler periodically to update the
per-cpu freq_scale variable.
The implementations now need to provide 'struct scale_freq_da
The Frequency Invariance Engine (FIE) is providing a frequency scaling
correction factor that helps achieve more accurate load-tracking.
Normally, this scaling factor can be obtained directly with the help of
the cpufreq drivers as they know the exact frequency the hardware is
running at. But that

On a typical end product, a vendor may choose to secure some regions in
the NAND memory which are supposed to stay intact between FW upgrades.
The access to those regions will be blocked by a secure element like

Hi Linus,
Please pull powerpc updates for 5.12.
There will be a conflict with the devicetree tree. It's OK to just take their

attention to just the user mapping's status isn't enough.
Also use GNTST_okay instead of implying its value (zero).
