| Subject: drm/amdgpu/powerplay/vega10: allow undervolting in p7 |
| |
| From: Pelle van Gils <pelle@vangils.xyz> |
| |
| commit e6f4e274c1e52d1f0bfe293fb44ddf59de6c0374 upstream. |
| |
| The vega10_odn_update_soc_table() function does not allow the SCLK |
| dependent voltage to be set for power-state 7 to a value below the default |
| in pptable. Change the for-loop condition to allow undervolting in the |
| highest state. |
