Introduction
The radeon driver has code like that for many GPU families:
if (!rdev->me_fw) {
r = r100_cp_init_microcode(rdev);
if (r) {
DRM_ERROR("Failed to load firmware!\n");
return r;
}
}
The result of that is that without the nonfree firmware, the radeon driver doesn't load.
Being able to use that driver, even if the 3D acceleration doesn't work without the nonfree firmware is very interesting:
- it can enable native resolution
- It supports multi-displays
