      drm/radeon/kms: R3XX-R4XX fix GPU reset code · a1e9ada3
      Jerome Glisse authored
      Previous reset code leaded to computer hard lockup (need to unplug
      the power too reboot the computer) on various configuration. This
      patch change the reset code to avoid hard lockup. The GPU reset
      is failing most of the time but at least user can log in remotely
      or properly shutdown the computer.
      
      Two issues were leading to hard lockup :
      - Writting to the scratch register lead to hard lockup most likely
      because the write back mecanism is in fuzy state after GPU lockup.
      - Resetting the GPU memory controller and not reinitializing it
      after leaded to hard lockup. We did only reinitialize in case of
      successfull reset thus unsuccessfull reset quickly leaded to hard
      lockup.
