Cool that they increased the accuracy, but where do you get that the
value can be negative? And if it is, how many bits are used? 16 or more?
What are those high bits?

pci_raw_set_power_state(), called by pci_set_power_state(), contains
this, which looks to me like it would be the only case where the problem
you're describing could be coming from:

dev->current_state = (pmcsr & PCI_PM_CTRL_STATE_MASK);
if (dev->current_state != state && printk_ratelimit())
dev_info(>dev, "Refused to change power state, currently 
in D%d\n",
 dev->current_state);

Do you happen to see this in the kernel logs? Perhaps this should be
considered an error rather than just an KERN_INFO level message?

Adding Bjorn and linux-pci for visibility.

 Since Kepler temperature sensors are able to report negative values. Those
 negative values are not for error reporting, but rather when you buried
 your GPU in snow somewhere in Antarctica and still want a valid
 temperature to be reported (unverified).

 Since Pascal (and maybe earlier) we have sensors with improved precision.

 Adjust the nvkm_get_temp method to be able to deal with those changes
 and let hwmon return an error properly.

I was asking rhyskidd to add stuff to rnndb, because he wrote the
nouveau patch for those sensors, check out for more details:
https://github.com/skeggsb/nouveau/blob/master/drm/nouveau/nvkm/subdev/therm/gp100.c#L27

regarding negative values, we have 0x02044c + 0x020450 for that and I
could imagine that 0x020460 can display negative values as well...
nobody tried for sure, but it seems plausible.

Anyway, moving from u8 to int should make life much easier for us if
we decide to really care about the higher precision. Currently our
code can't handle that for multiple reasons, but this solves one of
those at least.

We did not hear back from a lot of users about these issues, but I can
see that most GF108 vbios in our vbios repo are problematic, and some
GK106/GT215/GT216/GT218 might be too.

Yeah, this would hinder our reclocking efforts :s

The best idea I can come up with is to fake the temperature (register
0x20408) to 1°C (minimum the hardware allows us) and read the PWM duty,
then we can get the maximum duty by setting the temperature to the
fan_boost threshold.

Not sure we have a sure-way of computing the fan_boost threshold though,
maybe we can just use of the thermal throttling threshold for this (more
on this later in the email).

In any case, all of these solutions are workarounds. Given that the code
to compute these values is already found in vbioses, why is it a problem
to share the meaning of all the values in the fan calibration table,
and/or the algorithm?

> 
>>

Oh, thanks for giving me an idea about what the other values in this
table may be about :D

Anyways, the current code uses the entry id 0x46 of the thermal table
(bit P, offset 0x10) to find out what are the thermal points for
$fan_min and $fan_max. The $fan_min and $fan_max values are found in the
entry id 0x22 of the same table.

If the 0x46 entry is not present in the thermal table (which seems to be
the norm for Fermi), we revert to default values: 40 -> 85°C.

With these 4 values, we get 2 trip points (temp_min, fan_min)
and(temp_max, fan_max), and we merely do linear interpolation between them.

The manual toggle fans are only present on pre-tesla GPUs, let's ignore
them here, because we know what to do there.

All recent (2006+) GPUs use PWM, and anything after the GT215 use this
fan calibration table which took me a while to find, and that is still
mostly a mystery to me :s

Absolutely :) I have not updated Nouveau yet, in fear of setting a value
lower than what the proprietary driver does...

Unfortunately, it can also be the e11c/e120 couple, or 0x200d8/dc on
GF119+, or 0x200cd/d0 on Kepler+.

At least, it looks like we know which PWM controler we need to drive, so
I did not want to muddy the water even more by giving register
addresses, rather concentrating on the problem at hand: How to compute
the duty value for the PWM controler.

[Nouveau] [Bug 91523] [NVE7] driver cannot initialize gpu(failed to parse ramcfg data)

2017-11-22 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=91523

--- Comment #6 from FeepingCreature  ---
Looking at envytools' nvbios decode, given ramcfg=1, the first entry of the
timing mapping table (0x718f) has a value of 0xf at index 1, offset 0. This is
taken as index into the timing table (0x733c); however, the timing table only
defines 12 entries, and only six of them are nonzero.

If I simply skip entry 0, reclocking works fine. Maybe that's what 0x0f
indicates?

If you ever think you have the same problem as someone, file a new bug, and
make a mention of the fact that it *might* be related to some other bug.

All you're doing now is spamming other people's unrelated issues.

I think i have same problem.
Can reproduce error by play 4k video in mpv.
Or start Steam bigscreen mode.

I'm trying to install nvidia firmware, but system feels very slow and
unresponsive, and i can't test video or steam.

[Nouveau] [Bug 91523] [NVE7] driver cannot initialize gpu(failed to parse ramcfg data)

2017-11-22 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=91523

--- Comment #5 from default_357-l...@yahoo.de ---
I still get this error in 4.14.1. Same laptop, same vbios.rom. If I comment out
the "return ret" in
https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgk104.c#L1577,
it boots and runs 3d acceleration with xrandr offload, but cannot reclock
successfully.
