    Subject[PATCH 5.6 206/254] drm/amdgpu: unify fw_write_wait for new gfx9 asics
    Date
    From: Aaron Liu <aaron.liu@amd.com>

    commit 2960758cce2310774de60bbbd8d6841d436c54d9 upstream.

    Make the fw_write_wait default case true since presumably all new
    gfx9 asics will have updated firmware. That is using unique WAIT_REG_MEM
    packet with opration=1.
