2017-06-16drm/nouveau/disp/nv50-: implement a common supervisor 3.0Ben Skeggs
This makes use of all the additional routing and state added in previous commits, making it possible to deal with GM20x macro link routing, while also sharing code between the NV50 and GF119 implementations. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/devinit: use new devinit script interpreter entry-pointBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: add or/link args separate from output pathBen Skeggs
As of DCB 4.1, these are not the same thing. Compatibility temporarily in place until callers have been updated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: bump script offset to 32-bitsBen Skeggs
No (known) case yet, but other tables have been moving beyond 16-bits, so we may as well be prepared. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: rename 'crtc' to 'head'Ben Skeggs
Compatibility temporarily in place until all callers have been updated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: remove internal use of nvbios_init.biosBen Skeggs
We already have a subdev pointer, from which we can locate the device's BIOS subdev. No need for a separate pointer. Structure/callers not updated yet, as I want to batch more changes and only touch the callers once. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-06-16drm/nouveau/bios/iccsense: rails for power sensors have a mask of 0xf8 for ↵Karol Herbst
version 0x10 I only saw those values inside the vbios: 0xff, 0xfd, 0xfc, 0xfa for valid rails. No idea what the lower value does, but at least we get power readings on a lot of Fermi GPUs with that. v2: add missing parentheses Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/volt: Parse min and max for Version 0x40Karol Herbst

2017-02-17drm/nouveau/bios/power_budget: Add basic power budget parsingKarol Herbst
v2: Set entry to 0xff if not found Add cap entry for ver 0x30 tables Rework to fix memory leak v3: More error checks Simplify check for invalid entries v4: disable for ver 0x10 for now move assignments after the second last return Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-12-06drm/nouveau/bios/mxm: handle digital connector table 1.1Ben Skeggs
I suspect the version bump is just to signify that the table now specifies pad macro/links instead of SOR/sublinks. For our usage of the table, just recognising the new version is enough. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-10-12drm/nouveau/bios: Add parsing of VPSTATE tableKarol Herbst
This table contains three important clocks: base clock: This is the non boosted max clock. tdp clock: The clock at wich the vbios guarentees the TDP won't ever be exceeded at max load (seems to be always the same as the base clock, but behaves differently). boost clock: The avg clock the gpu will stay boosted to. It doesn't seem to affect the behaviour of the nvidia driver at all though. v2: Make clear that base/boost/tdp fields are ids. v5: Rename Base clock to vpstate. Make vbios pointers 32bit.

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/volt: Properly detect entry based voltage tablesKarol Herbst

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.

This is an oversight that made use of the trip-point-based fan managenent on cards that never expose those. This led the fan to stay at fan_min.
