Setting .compat_ioctl = radeon_compat_ioctl for KMS make 32bit ioctls work. But
there is still problem that stops ia32-glxinfo from working.
After starting ia32-glxinfo:
libGL: OpenDriver: trying /usr/lib32/dri/r300_dri.so
drm_radeon_getparam_t (RADEON_PARAM_DEVICE_ID): -14
libGL error: failed to create dri screen
[...]
In dmesg I only get this:
[10664.708003] [drm:radeon_info_ioctl] *ERROR* copy_to_user
I will check what drm debug=1 prints.
For now I thin that 32bit DRM_RADEON_INFO(radeon_kms.c:radeon_info_ioctl) fails
here:
"
if (DRM_COPY_TO_USER(value_ptr, &value, sizeof(uint32_t))) {
DRM_ERROR("copy_to_user\n");
return -EFAULT;
}
"
64bit one works as excepted.
