[5.0.0+] The buffer types for ReadBarRegion/WriteBarRegion were changed: 0x6 changed to 0x22, and 0x5 changed to 0x21.
=== QueryFunctions ===
Takes a type-0x6 output buffer containing an array of [[#FunctionState]]. Returns an output s32 '''Count'''.
=== AcquireFunction ===
Takes an input u32 '''FunctionHandle'''. Returns an output readable Event handle.
=== ReleaseFunction ===
Takes an input u32 '''FunctionHandle'''. No output.
=== GetFunctionState ===
Takes an input u32 '''FunctionHandle''' and a type-0x6 output buffer containing a [[#FunctionState]]. No output.
=== GetMappedBar ===
Takes two input u32s '''FunctionHandle''' and '''Bar'''. Returns an output u64 '''Address''' and an output [[#BarProfile]].
=== ReadConfig ===
Takes two input u32s '''FunctionHandle''', '''Offset''' and an input [[#BusAccessWidth]]. Returns an output u32 '''Config'''.
[7.0.0+] AcquireIrq now takes an additional 4-bytes of input, and no longer returns an output handle. SetAspmEnable now returns an output handle.
=== WriteConfig ===
Takes three input u32s '''FunctionHandle''', '''Offset''', '''Config''' and an input [[#BusAccessWidth]]. No output.
=== ReadBarRegion ===
Takes three input u32s '''FunctionHandle''', '''Bar''', '''Offset''', an input [[#BusAccessWidth]] and a type-0x6 output buffer. No output.
[5.0.0+] Now takes a type-0x22 output buffer instead.
=== WriteBarRegion ===
Takes three input u32s '''FunctionHandle''', '''Bar''', '''Offset''', an input [[#BusAccessWidth]] and a type-0x5 input buffer. No output.
[5.0.0+] Now takes a type-0x21 input buffer instead.
=== FindCapability ===
Takes an input u32s '''FunctionHandle''' and an input [[#CapabilityId]]. Returns an output u32 '''Capability'''.
=== FindExtendedCapability ===
Takes an input u32s '''FunctionHandle''' and an input [[#ExtendedCapabilityId]]. Returns an output u32 '''ExtendedCapability'''.
=== MapDma ===
Takes an input u32 '''FunctionHandle''', an input [[#DmaDirection]], an input u64 '''VirtualAddress''' and an input u32 '''Size'''. Returns an output u64 '''PhysicalAddress'''.
=== UnmapDma ===
Takes an input u32 '''FunctionHandle''' and an input u64 '''PhysicalAddress'''. No output.
=== UnmapDmaBusAddress ===
Takes an input u32 '''FunctionHandle''' and an input u64 '''BusAddress'''. No output.
=== GetDmaBusAddress ===
Takes an input u32 '''FunctionHandle''', an input u64 '''VirtualAddress''' and an input u32 '''Size'''. Returns an output u64 '''BusAddress'''.
=== GetDmaBusAddressRange ===
Takes an input u32 '''FunctionHandle'''. Returns two output u64s '''BusAddressRangeStart''' and '''BusAddressRangeEnd'''.
=== SetDmaEnable ===
Takes an input u32 '''FunctionHandle''' and an input bool '''Enable'''. No output.
=== AcquireIrq ===
Takes an input u32s '''FunctionHandle''' and an input [[#IrqType]]. Returns an output Event handle.
[7.0.0+] Now takes another input u32 and no longer returns an output Event handle.
=== ReleaseIrq ===
Takes an input u32 '''FunctionHandle'''. No output.
=== SetIrqEnable ===
Takes an input u32s '''FunctionHandle''', an unknown input u32 and an input bool '''Enable'''. No output.
=== SetAspmEnable ===
Takes an input u32 '''FunctionHandle''' and an input bool '''Enable'''. No output.
[7.0.0+] Now returns an output Event handle.
=== SetResetUponResumeEnable ===
Takes an input u32 '''FunctionHandle''' and an input bool '''Enable'''. No output.
=== ResetFunction ===
Takes an input u32 '''FunctionHandle''' and an unknown input u32. No output.
