Types and Values

Includes

#include <igt.h>

Description

This helper library contains simple functions to wrap the raw drm/i915 kernel ioctls. The normal versions never pass any error codes to the caller and use igt_assert() to check for error conditions instead. For some ioctls raw wrappers which do pass on error codes are available. These raw wrappers have a __ prefix.

For wrappers which check for feature bits there can also be two versions: The normal one simply returns a boolean to the caller. But when skipping the testcase entirely is the right action then it's better to use igt_skip() directly in the wrapper. Such functions have _require_ in their name to distinguish them.

Functions

igt_ioctl ()

int
(*igt_ioctl) (int fd,
              unsigned long  request,
              void *arg);

This is a wrapper around drmIoctl(), which can be augmented with special code blocks like igt_while_interruptible.

Parameters

fd

file descriptor

 

request

IOCTL request number

 

arg

argument pointer

 

gem_handle_to_libdrm_bo ()
