SMI/SCI Generation
Interrupts for power management events are not supported on legacy operating systems. To support
power management on non-PCI Express aware operating systems, PM events can be routed to
generate SCI. To generate SCI, MPC.PMCE must be set. When set, a power management event
will cause SMSCS.PMCS (D28:F0/F1/F2/F3:Offset DCh:bit 31) to be set.
Additionally, BIOS workarounds for power management can be supported by setting MPC.PMME
(D28:F0/F1/F2/F3:Offset D8h:bit 0). When this bit is set, power management events will set
SMSCS.PMMS (D28:F0/F1/F2/F3:Offset DCh:bit 0), and SMI # will be generated. This bit will be
set regardless of whether interrupts or SCI is enabled. The SMI# may occur concurrently with an
interrupt or SCI.
SERR# Generation
SERR# may be generated via two paths; through PCI mechanisms involving bits in the PCI header,
or through PCI Express mechanisms involving bits in the PCI Express capability structure.
Hot-Plug
Each root port implements a Hot-Plug controller which performs the following:
The root port only allows Hot-Plug with modules (e.g., ExpressCard*). Edge-connector based Hot-
Plug is not supported.
Presence Detection
When a module is plugged in and power is supplied, the physical layer will detect the presence of
the device, and the root port sets SLSTS.PDS (D28:F0/F1/F2/F3:Offset 5Ah:bit 6) and
SLSTS.PDC (D28:F0/F1/F2/F3:Offset 6h:bit 3). If SLCTL.PDE (D28:F0/F1/F2/F3:Offset 58h:
bit 3) and SLCTL.HPE (D28:F0/F1/F2/F3:Offset 58h:bit 5) are both set, the root port will also
generate an interrupt.
