Description
Reserved.
Reserved. Always set to 0.
VIP Clock Power Mode.
0: Disable clock gating. VIP clock is always ON.
1: Enable active hardware clock gating.
The VIP input clock to the video input block is enabled when this bit is 0. When this bit is
1, the VIP input clock is enabled whenever the VIP reset bit (VIP Memory Offset 00h[0])
is 0 or if VIP_MODE (VIP Memory Offset 00h bit [3:1]) is in a non 000 state. This bit
defaults to 1.
Reserved. Always set to 0.
GLIU Clock Power Mode.
0: Disable clock gating. GLIU clock is always ON.
1: Enable active hardware clock gating.
GLIU clock is always on if the VIP reset bit (VIP Memory Offset 00h[0]) is 0. When the
VIP reset bit is 1 and this bit is 1, the internal VIP GLIU clocks are only turned on in
response to requests (memory mapped read/writes and MSR read/writes) from the GLIU.
This bit defaults to 1.
