2019-12-05drm/amdgpu: add check before enabling/disabling broadcast modeGuchun Chen1-16/+22
When security violation from new vbios happens, data fabric is risky to stop working. So prevent the direct access to DF mmFabricConfigAccessControl from the new vbios and onwards.

2019-09-13drm/amd/amdgpu: add sw_fini interface for df_funcsJack Zhang1-0/+8
add sw_fini interface of df_funcs. This interface will remove sysfs file of df_cntr_avail function. The old behavior only create sysfs of df_cntr_avail in sw_init, but never remove it for lack of sw_fini interface. With this,driver will report create sysfs fail when it's loaded for the second time.

2018-06-01drm/amdgpu/df: fix potential array out-of-bounds readColin Ian King1-1/+1
The comparison with the number of elements in array df_v3_7_channel_number is off-by-one and can produce an array out-of-bounds read if fb_channel_number is equal to the number of elements of the array. Fix this by changing the comparison to >= instead of >.
