Detailed Description

Location "coordinates" for a CUDA device on a PCIe bus.

Note

can be compiled from individual values from a device's properties; see {properties_t}.

Member Function Documentation

parse() [1/2]

static pci_location_t cuda::device::pci_location_t::parse ( const ::std::string &  id_str )

static

Parse a string representation of a device's PCI location.

Note

This is not a ctor so as to maintain the PODness.

There are multiple notations for PCI IDs:

   domain::bus::device.function
domain::bus::device
bus::device.function

and any of them can be used.

parse() [2/2]

static pci_location_t cuda::device::pci_location_t::parse ( const char *  id_str )

static

Parse a string representation of a device's PCI location.

Note

This is not a ctor so as to maintain the PODness.

There are multiple notations for PCI IDs:

   domain::bus::device.function
domain::bus::device
bus::device.function

and any of them can be used.

Member Data Documentation

domain

optional<int> cuda::device::pci_location_t::domain

The four fields of the PCI configuration space.

Note

Only the first three are actually used/recognized by the CUDA driver, and when querying a CUDA device for its PCI ID, function will be unused. However - we have it be able to parse the different common string notations of PCI IDs; see https://wiki.xenproject.org/wiki/Bus:Device.Function_(BDF)_Notation .
