Userspace fails to properly set the upper 32bits and a 32 bit kernel
don't check the upper 32 bits :-)

Android-x86 4.0-r1 (32 bit) have problems with x86_64 kernel when he
trying to use a radeon kms. The following change correct a problem:
drivers/gpu/drm/radeon_kms.c (function radeon_info_ioctl):
- value_ptr = (uint32_t *)((unsigned long)info->value);
+ value_ptr = (uint32_t *)((unsigned)info->va
Hi!
I have problems running android-x86 (32 bit, 4.0-r1) with kernel 3.10
64 bit. Android drivers (binder and ashmem) are modified for this mode
(no problems). Problem is with radeon fb. Function radeon_iocl() is
failed on line: DRM_ERROR("copy_to_user %s:%u\n", __func__, __LINE__)
on request RADEO
Hi!
drivers/gpu/drm/radeon/radeon_kns.c: static int radeon_info_ioctl(...)
...
value_ptr = (uint32_t *)((unsigned long)info->value);
// value_ptr = (uint32_t __user *)(info->value); // looks like more
correct for x86_64
...
if (copy_to_user(value_ptr, (char*)value, value_size)) {...
Why value_ptr
Hi!
There is a notebook eMashines e442 142G25Mikk Model PEW86 with a video
card Radeon HD 4250. Since a kernel 3.7.10 (tested until 3.16.1) it
have a problem: screen is a white (not black) when PC is idle. A
changes causing problem is:
--- linux-3.6.11/drivers/gpu/drm/radeon/radeon_encoders.c
