* drm/nouveau/nv1a,nv1f/disp: fix memory clock rate retrievalIlia Mirkin2017-07-041-1/+2
| | | | | | | | | | | | | | commit 24bf7ae359b8cca165bb30742d2b1c03a1eb23af upstream. Based on the xf86-video-nv code, NFORCE (NV1A) and NFORCE2 (NV1F) have a different way of retrieving clocks. See the nv_hw.c:nForceUpdateArbitrationSettings function in the original code for how these clocks were accessed.

* drm/nv50/disp: min/max are reversed in nv50_crtc_gamma_set()Dan Carpenter2017-06-171-1/+1
| | | | | | | | | | | | | | | commit bdefc8cbdfc71ea73e0573dbd2d24c0a68232218 upstream. We should be taking the minimum here instead of the max. It could lead to a buffer overflow.

* drm/nouveau/gem: return only valid domain when there's only oneIlia Mirkin2016-08-261-2/+3
| | | | | | | | | | | | | | | | | | | | | commit 2a6c521bb41ce862e43db46f52e7681d33e8d771 upstream. On nv50+, we restrict the valid domains to just the one where the buffer was originally created. However after the buffer is evicted to system memory, we might move it back to a different domain that was not originally valid. When sharing the buffer and retrieving its GEM_INFO data, we still want the domain that will be valid for this buffer in a pushbuf, not the one where it currently happens to be. This resolves fdo#92504 and several others. These are due to suspend evicting all buffers, making it more likely that they temporarily end up in the wrong place.
