AMD chipsets have proprietary mechanisms for dicovering resources. Those resources are not discoverable via plug-and-play mechanisms like PCI configuration registers or ACPI. For this reason a chipset-specific knowledge of proprietary registers is required. At present there are two FreeBSD drivers that require the proprietary resource discovery. One is amdsbwd which is a driver for the watchdog timer in the AMD chipsets. The other is intpm SMBus driver when it attaches to the newer AMD chipsets where the resources of the SMBus HBA are not described in the regular PCI way. In both cases the resources are discovered by accessing AMD PMIO space. Thus, many definitions are shared between the two drivers. This change puts those defintions into a common header file. As an added benefit, intpm driver now supports newest FCHs built into AMD processors of Family 15h, models 70h-7Fh and Family 16h, models 30h-3Fh.

.Sh BUGS
|
|
This device requires IRQ 9 exclusively.
|
|
To use this, you should enable
|
|
ACPI function in BIOS configuration, or PnP mechanism assigns conflicted
|
|
IRQ for PnP ISA card.
|
|
And do not use IRQ 9 for Non-PnP ISA cards.
