commit aa6158112645aae514982ad8d56df64428fcf203 upstream.

Navi series GPUs have 2 SIMDs per CU (and then 2 CUs per WGP).
The NV enum headers incorrectly listed this as 4, which later meant
we were incorrectly reporting the number of SIMDs in the HSA
topology. This could cause problems down the line for user-space
applications that want to launch a fixed amount of work to each
SIMD.

Enable DCS

V1: Enable Async DCS.
V2: Add the ppfeaturemask bit to enable from the modprobe parameter.
V3:
1. add the flag to skip APU support.
2. remove the hunk for workload selection since
it doesn't impact the function.

<title>drm/amd/pm: implement processor fine grain feature for vangogh (v3)</title>

<id>0d90d0ddd10e576dbbad64486c263e5e86bbcdd7</id>
<content type='text'>
This patch is to implement the processor fine grain feature for vangogh.
It's similar with gfx clock, the only difference is below:

echo "p core_id level value" &gt; pp_od_clk_voltage

1. "p" - set the cclk (processor) frequency
2. "core_id" - 0/1/2/3, represents which cpu core you want to select
2. "level" - 0 or 1, "0" represents the min value,  "1" represents the
   max value
3. "value" - the target value of cclk frequency, it should be limited in
   the safe range

v2: fix some missing changes as Evan's suggestion.
v3: add version check and fix the restore.

<title>drm/amd/pm: support overdrive vddgfx offset setting(V2)</title>

<id>a2b6df4fd6e3c0ba088b00fc00579dac263b0a64</id>
<content type='text'>
This is supported by Sienna Cichlid, Navy Flounder and Dimgrey
Cavefish. For these ASICs, the target voltage calculation can be
illustrated by "voltage = voltage calculated from v/f curve +
overdrive vddgfx offset".

V2: limit the smu_version check for Sienna Cichlid only

Here are some sample usages about this new OD setting:
1. Check current vddgfx offset setting by
cat /sys/class/drm/card0/device/pp_od_clk_voltage
...
...
OD_VDDGFX_OFFSET:
0mV
...
...

2. Set new vddgfx offset by
echo "vo 10" &gt; /sys/class/drm/card0/device/pp_od_clk_voltage
cat /sys/class/drm/card0/device/pp_od_clk_voltage
...
...
OD_VDDGFX_OFFSET:
10mV
...
...
3. Commit the new setting by
echo "c" &gt; /sys/class/drm/card0/device/pp_od_clk_voltage

illustrated by "voltage = voltage calculated from v/f curve +
overdrive vddgfx offset".

V2: limit the smu_version check for Sienna Cichlid only

Here are some sample usages about this new OD setting:
1. Check current vddgfx offset setting by
cat /sys/class/drm/card0/device/pp_od_clk_voltage
...
...
OD_VDDGFX_OFFSET:
0mV
...
...

2. Set new vddgfx offset by
echo "vo 10" &gt; /sys/class/drm/card0/device/pp_od_clk_voltage
cat /sys/class/drm/card0/device/pp_od_clk_voltage
...
...
OD_VDDGFX_OFFSET:
10mV
...
...
3. Commit the new setting by
echo "c" &gt; /sys/class/drm/card0/device/pp_od_clk_voltage

v1: add osssys v4_2 register offset and shift masks
header files. vega20 and arcturus will refer to
these ip headers. (Hawking)
v2: clean up osssys v4_2 registers (Alex)
