Subject: [PATCH 0/2] Fixes of AMD GFX7/8 hang on Loongson platforms

This patchset tries to fix some workaround code in amdgpu/radeon driver,
that makes Loongson 3A+7A platform suffering from GPU crashes.

Icenowy Zheng (2):
  drm/amdgpu: make duplicated EOP packet for GFX7/8 have real content
  drm/radeon: repeat the same EOP packet for EOP workaround on CIK
