GLCP_CLKACTIVE (MSR 51700011h) shows that
those clocks are indeed inactive, disable the clocks

51700009h).
Sleep Acknowledge is asserted after the clocks have
been disabled. The wakeup sequence is triggered by
the de-assertion of the Sleep Request, which turns on
all the clocks.
If a debug event in the debug circuitry triggers a clock
disable,
GLCP_CLKDISABLE. Each GLCP_CLKDISABLE bit
corresponds to a CCU, and when set, indicates that
the clock going to that CCU should be disabled.
Each bit in GLCP_CLKOFF (MSR 51700010h) corre-
sponds to a CCU. When set, the bit indicates that the
clock going to that CCU should be disabled. This is the
simplest case.

The GLCP has multiple clock domains, namely the
GeodeLink clock and PCI clock. The GeodeLink clock is
the clock source for the MSRs, the serial interface, and the
GeodeLink interface. The PCI clock is used in the power
management support for the clock disable delay timer.
Both the GeodeLink and PCI functional clocks come from
primary inputs. All these clocks are handled by a CCU.
Even though the PCI clock is always running in functional
mode, a CCU is needed to be able to perform reset syn-
chronization and to turn off the internal clock to support
TAPSCAN. The CCUs used by the GLCP are the asyn-
chronous versions, since the GLCP outputs asynchronous
busy signals.
