Register names for PCH P2SB device
|
|
Conventions:
|
|
- Register definition format:
|
Prefix_[GenerationName]_[ComponentName]_SubsystemName_RegisterSpace_RegisterName
|
- Prefix:
|
Definitions beginning with "R_" are registers
|
Definitions beginning with "B_" are bits within registers
|
Definitions beginning with "V_" are meaningful values within the bits
|
Definitions beginning with "S_" are register size
|
Definitions beginning with "N_" are the bit position
|
- [GenerationName]:
|
Three letter acronym of the generation is used (e.g. SKL,KBL,CNL etc.).
|
Register name without GenerationName applies to all generations.
|
- [ComponentName]:
|
This field indicates the component name that the register belongs to (e.g. PCH, SA etc.)
|
Register name without ComponentName applies to all components.
|
Register that is specific to -LP denoted by "_PCH_LP_" in component name.
|
- SubsystemName:
|
This field indicates the subsystem name of the component that the register belongs to
|
(e.g. PCIE, USB, SATA, GPIO, PMC etc.).
|
- RegisterSpace:
|
MEM - MMIO space register of subsystem.
|
IO - IO space register of subsystem.
|
PCR - Private configuration register of subsystem.
|
CFG - PCI configuration space register of subsystem.
|
- RegisterName:
|
Full register name.
