Ben Skeggs 27740383dd drm/nva3/pm: initial attempt at more magic PFB regs
The reg calculation may get moved elsewhere at some point, but lets
figure out what exactly we need to do first.

Ben Skeggs fd99fd6100 drm/nouveau/pm: calculate memory timings at perflvl creation time
Statically generating the PFB register and MR values for each timing set
turns out to be insufficient.  There's at least one (so far) known piece
of information which effects MR values which is stored in the perflvl
entry on some chipsets (and in another table on later ones), which is
disconnected from the timing table entries.

After this change we will generate a timing set based on an input clock
frequency instead, and have this data stored in the performance level
data.

Ben Skeggs 03ddf04bdb drm/nouveau/pm: restructure bios table parsing
It turns out we need access to some additional information in various VBIOS
tables to handle PFB memory timings correctly.

Rather than hack in parsing of the new stuff in some kludgy way, I've
restructured the VBIOS parsing to be more primitive, so we can use them in
more flexible ways in the future.

The perflvl->timing association code is disabled for the moment until it can
be reworked.  We don't use this stuff yet anyway, so no harm done.

Ben Skeggs f3fbaf34e2 drm/nv50/pm: rewrite clock management, and switch to the new pm hooks
This area is horrifically complicated on these chipsets, and it's likely we
will need at least a few more tweaks yet.

Oh yes, and it's completely disabled on IGPs for the moment.  From traces,
things look potentially different there yet again.  Sigh...

Ben Skeggs 9f403603f2 drm/nv40/pm: parse geometric delta clock from vbios
This changes the meaning of what we reported as "core" clock previously.

The shader/rop units are allegedly supposed to be run at the base clock
listed in the perf table, while the geometric clock can be bumped from
this value on some boards.

So that we can report both, we'll report the base clock as "shader" (since
the shaders *do* run at it), and the geometric clock as "core".

Emil Velikov 2905544073 drm/nouveau/pm: Prevent overflow in nouveau_perf_init()
While parsing the perf table, there is no check if
the num of entries read from the vbios is less than
the currently allocated number.

In case of a buggy vbios this will cause overwriting
of kernel memory, causing aditional problems.

Add a simple check in order to prevent the case

Ben Skeggs 96d1fcf8b5 drm/nouveau/pm: translate ramcfg strap through ram restrict table
Hopefully this is how we're supposed to correctly handle when the RAMCFG
strap is above the number of entries in timing-related tables.

It's rather difficult to confirm without finding a configuration where
the ram restrict table doesn't map 8-15 back onto 0-7 anyway.  There's
not a single vbios in the repo which is configured differently..

In any case, this is probably still better than potentially reading
outside of the bounds of various tables..

Francisco Jerez 0fbb114af7 drm/nouveau: Parse old style perf tables.
Used on nv17-nv28, they contain memory clocks and timings, only one of
the table entries can actually be used, depending on the RAMCFG
straps, and it's usually higher than the frequency programmed on boot
by the BIOS.

The memory timings listed in table version 0x1x are used to init the
0x12xx range but they aren't required for reclocking to work.
