+AMDGPU RAS Support
88
+==================
89
+
90
+The AMDGPU RAS interfaces are exposed via sysfs (for informational queries) and
91
+debugfs (for error injection).

+Sample Code
124
+-----------
125
+Sample code for testing error injection can be found here:
126
+https://cgit.freedesktop.org/mesa/drm/tree/tests/amdgpu/ras_tests.c
127
+
128
+This is part of the libdrm amdgpu unit tests which cover several areas of the GPU.
129
+There are four sets of tests:
130
+
131
+RAS Basic Test
132
+
133
+The test verifies the RAS feature enabled status and makes sure the necessary sysfs and debugfs files
134
+are present.
135
+
136
+RAS Query Test
137
+
138
+This test checks the RAS availability and enablement status for each supported IP block as well as
139
+the error counts.
140
+
141
+RAS Inject Test
142
+
143
+This test injects errors for each IP.
144
+
145
+RAS Disable Test
146
+
147
+This test tests disabling of RAS features for each IP block.
