Subject: [PATCH] regulator: fan53555: fix TCS4525 voltage calulation
|
||||
|
||||
The TCS4525 has 128 voltage steps. With the calculation set to 127 the
|
||||
most significant bit is disregarded which leads to a miscalculation of
|
||||
the voltage by about 200mv.
|
||||
|
||||
Fix the calculation to end deadlock on the rk3566-quartz64 which uses
|
||||
this as the cpu regulator.
|
||||
|
||||

Subject: [PATCH] drm/panfrost: Add governor data with pre-defined thresholds
|
||||
|
||||
The simple_ondemand devfreq governor uses two thresholds to decide about
|
||||
the frequency change: upthreshold, downdifferential. These two tunable
|
||||
change the behavior of the governor decision, e.g. how fast to increase
|
||||
the frequency or how rapidly limit the frequency. This patch adds needed
|
||||
governor data with thresholds values gathered experimentally in different
|
||||
workloads.

Subject: [PATCH] drm/lima: add governor data with pre-defined thresholds
|
||||
|
||||
This patch adapts the panfrost pre-defined thresholds change [0] to the
|
||||
lima driver to improve real-world performance. The upthreshold value has
|
||||
been set to ramp GPU frequency to max freq faster (compared to panfrost)
|
||||
to compensate for the lower overall performance of utgard devices.
