Detailed Description

GPU Information.

This class typically contains information about a DRM node, however, its properties could have different meanings when using virtualized backends.

To see all available devices, use LSeat::gpus(). For a particular output, use LOutput::gpu().

Member Function Documentation

name()

const std::string& name ( ) const

inlinenoexcept

Gets the GPU name.

When using the DRM backend, this can be, e.g., /dev/dri/card0.

dev()

dev_t dev ( ) const

inlinenoexcept

Gets the Unix device identifier.

id()

int id ( ) const

inlinenoexcept

Gets the Libseat device ID.

Returns

A Libseat device ID, or -1 if the device was not opened with Libseat.

fd()

int fd ( ) const

inlinenoexcept

Gets the read-write file descriptor.

Warning

Do not attempt to close it or use it unless you know what you're doing.

Returns

A read-write file descriptor, or -1 if the backend doesn't provide it.

roFd()

int roFd ( ) const

inlinenoexcept

Gets the read-only file descriptor.

Returns

A read-only file descriptor, or -1 if the backend doesn't provide it.
