Relative Priorities of SVC, PendSV, Systick in RTOSes

I know that RTX uses the following system exception priorities, on my MCU (silabs efm32gg, CM3-based) with 3 priority bits SVC = 6 PendSV = Systick = 7, where lower numeric value is higher priority...
Raising priority of PendSV within NVIC when PendSV pending

Hi, I'm trying to understand the behavior of raising (lowering numerical priority) the priority of PendSV in the NVIC of a Cortex M4 or M7 when PendSV is already pending. Below are the cases I'm grappling...
