NVA3: Small misc mem reclocking fixes
Patch 1 fixes nva3 bailing due to not finding the right ramcfg
Patch 2 is a resend rebased on 3.17.0-rc4 for setting the vblank period
Patch 3-5 handle writes to per-partition registers, for which NVA3 does not
have special broadcast regs available.
Patch 6 removes local structs from NVA3 reclocking in favour of the already
existing "ram->base." variables, like in NVE0
As always,

[RFC] Fermi/Kepler identify DLLoff
Hello,
Attached a small patch that correctly identifies the DLLoff bit for >=GF100.
Marked RFC because I haven't seen any GDDR5 samples that *enable* the DLL. I'd
like to verify whether the DLL should be reset when enabled. Could increase
likelihood of succesfull reclock.
Ben: could you do some experiments with this bit to see if GDDR5 needs some DLL
reset logic?
Thanks, and happy

All-round reclocking improvements
In bulletpoints:
- Add some support for G94 and G96 reclocking. Has been tested on literally
two cards, which is hardly adequate as "full coverage". On the other hand,
the changes were small enough to make me confident this might work for others
as well.
- Fix NV50 wait for VBLANK when no monitor is plugged in.
- Voltage related inprovements for GT21x.
- Slightly improve Keplers

RESEND Preparations for Fermi DRAM clock changes
Two patches went missing as a result of PEBCAK. No v2 marks as nothing
changed really. Just resending for easier enforcement of patch order
in other people's trees. Sorry for the noise.
Original message:
No, no, these will not implement Fermi reclocking. This set of patches
contains some of the preparatory work that I deem stable enough to
move upstream. Notable changes
- Training pattern

Preparations for Fermi DRAM clock changes
No, no, these will not implement Fermi reclocking. This set of patches
contains some of the preparatory work that I deem stable enough to
move upstream. Notable changes
- Training pattern upload routines from GK104+ now shared with GT215+
- Timing calculation for Fermi
- GDDR5 MR calculation from VBIOS timing table v1.0. Also useful for that
pesky GT 240.
- A routine to translate a VBIOS init

Reclocking support for NVA0
Adds reclocking for NVA0, and a whole lot of work for other cards. Had these
patches collecting dust for a little, but tested them with both my NVA0,
and Martin's a while back. Success not guaranteed, but should be quite a
leap forward.
Happy reviewing and testing. Cheers,
Roy

MEMX improvements + DDR 2/3 MR generation
Patch 1 and 2 implement wait-for-vblank, required to remove flicker when reclocking memory
Patch 3 and 4 allow me to do things between waiting for VBLANK and disabling FB, like pause PFIFO and wait for the engines to idle. This minimises the time PFIFO is paused, thus maximises performance.
The rest of the patches speak for themselves. As the actual memory reclocking script is still somewhat prone

[PATCH 0/5] GPU-DRM-nouveau: Fine-tuning for five function implementations

A few update suggestions were taken into account
from static source code analysis.

Use kmalloc_array() in gt215_link_train()
Delete unnecessary braces
Adjust a kzalloc() call in gt215_ram_new()

[PATCH v5 00/20] Engine Reclocking Fixes for Fermi-Maxwell2
I've splitted my big series between the part which actually fixes the
engine reclocking bits and the part handling voltage/clock updates on
temperature change, so that the more reviewed parts can be merged in
faster.
This series fixes a lot of Engine reclocking issues found on Fermi, Kepler
and all Maxwell generation GPUs. It does _not_ fix memory reclocking on
Fermi.

- add fan_type (toggle or PWM)
v2:
- Do not memset the table to 0 as it erases the pre-set default values

[PATCH] pmu/fuc: don't use movw directly anymore
fixes compilation issues with recent envytools, because movw was removed
from fuc5, because it doesn't exist there anymore. The current code is
most likely broken for fuc5 hardware as well and might have triggered all
kinds of random memory reclocking fails.
Changes in fuc3 binaries are tue do opcode optimizations using shorter
opcodes when possible.

[PATCH 0/4] PMU engine counters
these are usually used for dynamic reclocking on gt215 and newer
The counters are used to get the load of the core, memory, video and pcie loads
currently I expose the loads through a debugfs "current_load" file, but I want
to move that to nvif and just add a wrapper around that in debugfs for
convenience
Anyway there are still some issues I would like to discuss:
