+Subject: [PATCH 0834/4131] drm/amdkfd: Reject devices without host atomic
+ support
+
+HSA requires atomic operations from device to host for all ASICs from
+Gfx8 onwards. APUs implicitly support this through ATS. Discrete GPUs
+require PCI support to route atomics to the host bridge and complete
+them.
+
+Do not bind to PCI devices which cannot route atomics to the host.
