4 years agodrm/amd/display: Only revalidate bandwidth on medium and fast updates

drm/amd/display: Only revalidate bandwidth on medium and fast updates

[Why]
Changes that are fast don't require updating DLG parameters making
this call unnecessary. Considering this is an expensive call it should
not be done on every flip.

DML touches clocks, p-state support, DLG params and a few other DC
internal flags and these aren't expected during fast. A hang has been
reported with this change when called on every flip which suggests that
modifying these fields is not recommended behavior on fast updates.

[How]
Guard the validation to only happen if update type isn't FAST.

4 years agodrm/amd/powerplay: Fix NULL dereference in lock_bus() on Vega20 w/o RAS

...

Error appears when some i2c device driver tries to probe for devices
using adapter registered by `smu_v11_0_i2c_eeprom_control_init()`.
Code supporting this adapter requires `adev->psp.ras.ras` to be not
NULL, which is true only when `amdgpu_ras_init()` detects HW support by
calling `amdgpu_ras_check_supported()`.

Before 9015d60c9ee1, adapter was registered by

-> amdgpu_device_ip_init()
  -> amdgpu_ras_recovery_init()
    -> amdgpu_ras_eeprom_init()
      -> smu_v11_0_i2c_eeprom_control_init()

after verifying that `adev->psp.ras.ras` is not NULL in
`amdgpu_ras_recovery_init()`. Currently it is registered
unconditionally by

-> amdgpu_device_ip_init()
  -> pp_sw_init()
    -> hwmgr_sw_init()
      -> vega20_smu_init()
        -> smu_v11_0_i2c_eeprom_control_init()

Fix simply adds HW support check (ras == NULL => no support) before
calling `smu_v11_0_i2c_eeprom_control_{init,fini}()`.

Please note that there is a chance that similar fix is also required for
CHIP_ARCTURUS. I do not know whether any actual Arcturus hardware without
RAS exist, and whether calling `smu_i2c_eeprom_init()` makes any sense
when there is no HW support.

4 years agodrm/amd/display: Fill in dmub_srv fw_version from firmware metadata

drm/amd/display: Fill in dmub_srv fw_version from firmware metadata

[Why]
DMCUB firmware version is now available from firmware metadata block.

We should be passing this into dmub_srv so we can know when to apply
firmware version specific functionality like using CW4 only instead
of the REGION4.

[How]
We don't have the helpers for DM to actually extract out firmware
metadata block themselves.

We could add that and add helpers in DM to grab this, but not every
creation sequence has firmware instruction before dmub_srv_create.

Easiest way to handle this is to fill this in automatically per DM in
the place we do have it - when calculating the region parameters. But
only fill it in if DM already hasn't in case we need to override with
a specific version.

We aren't do anything firmware version specific in dmub_srv_create
today that does require fw_version, so while it's a little unituitive
to do it when calculating region parameters it works for now.
