/*
* In DCN2.1, the non-double buffered version of the following 4 DLG registers are used in RTL.
* As a result, if S/W updates any of these registers during a mode change,
* the current frame before the mode change will use the new value right away
* and can lead to generating incorrect request deadlines and incorrect TTU/QoS behavior.

* REFCYC_PER_VM_REQ_FLIP[22:0]
* REFCYC_PER_VM_REQ_VBLANK[22:0]
*
* REFCYC_PER_VM_*_FLIP affects the deadline of the VM requests generated
* when flipping to a new surface
*
* REFCYC_PER_VM_*_VBLANK affects the deadline of the VM requests generated
* during prefetch period of a frame. The prefetch starts at a pre-determined
* number of lines before the display active per frame
*
* DCN may underflow due to incorrectly programming these registers
* during VM stage of prefetch/iflip. First lines of display active
* or a sub-region of active using a new surface will be corrupted
* until the VM data returns at flip/mode change transitions
*
* Work around:
* workaround is always opt to use the more aggressive settings.
* On any mode switch, if the new reg values are smaller than the current values,
* then update the regs with the new values.
