[PATCH] drm/nouveau/kms/gf119-: allow both 256- and 1024-sized LUTs to be used
The hardware supports either size. Also add checks to ensure that only these two sizes may be used for supplying a LUT. Finally, experimental evidence suggests you can't mix sizes for degamma and gamma. Disallow this as well. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- Note that all the gv100+ changes are purely speculative. Tested on a GK208 with 8- and 10-bpc formats

The hardware supports either size. Also add checks to ensure that only these two sizes may be used for supplying a LUT. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- Only tested on G84 and GK208. The GV100+ is entirely untested. With the fixed modetest tool, setting ilut and olut sizes to different quantities seems to work out OK, across a range of formats (XR24, XB30, XB4H).

[PATCH v3 4/4] drm/nouveau: Move PBN and VCPI allocation into nv50_head_atom
Atomic checks should never modify anything outside of the state that they're passed in. Unfortunately this appears to be exactly what we're doing in nv50_msto_atomic_check() where we update mstc->pbn every time the function is called. This hasn't caused any bugs yet, but it needs to be fixed in order to ensure that when committing an artificially duplicated state (like during system

[PATCH 6/9] drm/nouveau/kms/nv140-: Track wndw mappings in nv50_head_atom
While we're not quite ready yet to add support for flexible wndw mappings, we are going to need to at least keep track of the static wndw mappings we're currently using in each head's atomic state. We'll likely use this in the future to implement real flexible window mapping, but the primary reason we'll need this is for CRC support. See: on nvidia hardware, each CRC entry in

[PATCH 1/4] drm/nouveau: dispnv50: Don't create MSTMs for eDP connectors
On the ThinkPad P71, we have one eDP connector exposed along with 5 DP connectors, resulting in a total of 11 TMDS encoders. Since the GPU on this system is also capable of MST, we create an additional 4 fake MST encoders for each DP port. Unfortunately, we also do this for the eDP port as well, resulting in: 1 eDP port: +1 TMDS encoder +4 DPMST encoders 5 DP ports: +2 TMDS
