Commit Message

Rodrigo Siqueira May 27, 2019, 1:19 a.m. UTC
The function __kms_addfb() and drmModeAddFB2WithModifiers() have a
similar code. Due to this similarity, this commit replaces all the
occurrences of  __kms_addfb() by drmModeAddFB2WithModifiers() and adds
the required adaptations.

V2: Simon Sir
 - Fix array data copy

V1: Arkadiusz Hiler
 - Fix array initialization
 - Drop __kms_addfb()

No. There is a critical difference between the two: igt_ioctl. That
allows us to control the ioctl for error injection into the kernel.

If you want to test libdrm API and not the kernel, please add tests
to libdrm.

Hi Chris,

Thank you for your feedback and the explanation about igt_ioctl, now
I've got it.
