2016-10-12drm/nouveau/volt: Add temperature parameter to nvkm_volt_mapKarol Herbst
The voltage entries actually may map to a different voltage depending on the current temperature. v2: Only read the temperature when actually needed. v5: Be smarter about using max(). Don't read the temperature anymore. Signed-off-by: Karol Herbst <karolherbst@gmail.com> Reviewed-by: Martin Peres <martin.peres@free.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-10-12drm/nouveau/clk: Let nvkm_clk_tstate take a temperature valueKarol Herbst
This way other subdevs can notify the clk subdev about temperature changes without the need of clk to poll that value. Also make this function safe to be called from an interrupt handler. Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-10-12drm/nouveau/clk: Add index field to nvkm_cstateKarol Herbst
It is better to read out the id out of the cstate struct directly instead of iterating over the list of cstates over and over again. Especially when we start saving pointers to a nvkm_cstate struct, it makes things easier. v5: Rename field to id.

2016-10-12drm/nouveau/volt: Add min_id parameter to nvkm_volt_set_idKarol Herbst
Each pstate has its own voltage map entry like each cstate has. The voltages of those entries act as a floor value for the currently selected pstate and nvidia never sets a voltage below them.

2016-10-12drm/nouveau/volt: Parse the max voltage map entriesKarol Herbst
There are at least three "max" entries, which specify the max voltage. Because they are actually normal voltage map entries, they can also be affected by the temperature. Nvidia respects those entries and if they get changed, nvidia uses the lower voltage from all three. We shouldn't exceed those voltages at any given time. v2: State what those entries do in the source. v3: Add the third max entry. v5: Better describe the entries.

2016-10-12drm/nouveau/clk: Don't create cstates with voltages higher than what the gpu ↵Karol Herbst
can do nvkm_volt_map_min is a copy of nvkm_volt_map, which always returns the lowest possible voltage for a cstate. nvkm_volt_map will get a temperature parameter there later and also fix the voltage calculation, so that this functions will be completly different later.

2016-10-12drm/nouveau/volt: Properly detect entry based voltage tablesKarol Herbst
There is a field in the voltage table which tells us if the VIDs are taken from the entries or calculated through the header. v2: Don't break older versions. v5: Reverse flag name.

2016-10-12drm/nouveau/bios/volt: Handle voltage table version 0x50 with zeroed headerKarol Herbst
Some Fermi+ GPUs specify VID information via voltage table entries, rather than describing them as a range in the header. The mask may be bigger than 0x1fffff, but this value is already >2V, so it will be fine for now. This patch fixes volting issues on those cards enabling them to switch cstates. v6: rework message Signed-off-by: Karol Herbst <karolherbst@gmail.com> Reviewed-by: Martin Peres <martin.peres@free.fr> Tested-by: Pierre Moreau <pierre.morrow@free.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-10-12drm/nouveau/iccsense: Parse the resistors and config the right wayKarol Herbst
Previously we parsed that table a bit wrong: 1. The entry layout depends on the sensor type used. 2. We have all resitors in one entry for the INA3221. 3. The config is already included in the vbios. This commit addresses that issue and with that we should be able to read out the right power consumption for every GPU with a INA209, INA219 and INA3221.

2016-10-12Merge tag 'drm-for-v4.9' into drm-intel-next-queuedDaniel Vetter
It's been over two months, git definitely lost it's marbles. Conflicts resolved by picking our version, plus manually checking the diff with the parent in drm-intel-next-queued to make sure git didn't do anything stupid. It did, so I removed 2 occasions where it double-inserted a bit of code. The diff is now just - kernel-doc changes - drm format/name changes - display-info changes so looks all reasonable.
