This patch is to improve the fine grain tuning function for RV/RV2/PCO.
This patch adds two new commands: "restore" and "commit".
This function uses the pp_od_clk_voltage sysfs file to configure the min
and max value of gfx clock frequency manually or restore the default value.
Command guide:
echo "s level value" > pp_od_clk_voltage
"s" - set the sclk frequency
"level" - 0 or 1, "0" represents the min value, "1" represents
the max value
"value" - the target value of sclk frequency, it should be limited in the
safe range
echo "r" > pp_od_clk_voltage
"r" - reset the sclk frequency, restore the default value instantly
echo "c" > pp_od_clk_voltage
"c" - commit the min and max value of sclk frequency to the system
only after the commit command, the target values set by "s" command
will take effect.
Example:
1)change power profile from "auto" to "manual"
$ cat power_dpm_force_performance_level
auto
$ echo "manual" > power_dpm_force_performance_level
$ cat power_dpm_force_performance_level
manual
2)check the default sclk frequency
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
3)use "s" -- set command to configure the min and max sclk frequency
$ echo "s 0 600" > pp_od_clk_voltage
$ echo "s 1 1000" > pp_od_clk_voltage
$ echo "c" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 600Mhz
1: 1000Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
4)use "r" -- reset command to restore the min or max sclk frequency
$ echo "r" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz

This patch is to enable the "fetch" function of pp_dpm_vclk and
pp_dpm_dclk.
It allows to fetch the current frequency of vcn and dcn and their

This patch is to add two new sysfs nodes for vangogh:
pp_dpm_dclk and pp_dpm_vclk.
The two sysfs nodes are similar to pp_dpm_fclk/memclk/socclk.
pp_dpm_dclk represents the DPM frequency of dcn unit.
pp_dpm_vclk represents the DPM frequency of vcn unit.

Vangogh uses one different format to name some feature bits of swSMU, it

clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.
This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.
So just initialize 'val' to zero to avoid the issue.

We can have the same src ids for different client ids so make sure to
check both the client id and the source id when handling interrupts.

We need to take into account the client id otherwise we'll end
up sending generic events for any src id that is registered.
We only support irq domains on pre-soc15 parts so client is
always legacy.

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" > /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" > /sys/class/drm/card0/device/pp_od_clk_voltage

When user specifies a reduced WGP(CU) config via disalbe_cu module
parameter, this does not disable the clocks which uses additional
power. This interface send active WGP number to SMU and SMU will
cooperate with RLC to power off relative WGPs.
v2: Add request active WGPs in Vangogh smu post init.

For all the ASICs that integrate psp v11, vega20
doesn't support ih reroute. arcturus and later will
allow kernel driver to program ih_cfg_index/data
through mmio directly. navi1x and onwards will only
support grb_ih_set command in sriov configuration.
psp_v11_0_reroute_ih is not needed any more.
