 # Supported Primitives
 
+General limitations:
+
+* Currently blocked formats are not supported by any implementation unless
+    explicitly listed
+* There's a limit of maximum 5 post-ops for the implementations
+* The maximum supported size of any dimension of any input/output tensor of a
+    primitive is `INT32_MAX`
+
 ## Batch Normalization
 
 The implementation supports both forward and backward directions.
 
 * Supported formats: `NCDHW`, `NDHWC`, `NCHW`, `NHWC`, `NCW`, `NWC`, `NC`
+* Supported data types
+    * Forward direction: `f32`, `bf16`, `f16`, `s8`
+    * Backward direction: `f32`, `bf16`, `f16`
+
+## Binary
+
+* Supported formats: plain formats, `Ab32a`, `aBc32b`
+* Supported data types: `f32`, `bf16`, `f16`, `s8`, `u8`, `s32`
+
+## Convolution
+
+The implementation supports forward, backward data and backward weights
+directions.
+
+* Supported input/output formats: plain formats
+* Supported weights formats: `goiw`, `goihw`, `goidhw`, `oiw`, `oihw`, `oidhw`;
+* Supported data types: `f32`, `bf16`, `f16`, `s32`, `s8`, `u8`
+* Limitations
+    * Some very large problem sizes currently return `unimplemented` due to an
+      issue with long execution times
+
+## Concat
+
+A generic Concat implementation which uses the Reorder primitive is used. Refer
+to [src/gpu/generic/ref_concat.hpp](../ref_concat.hpp) for more information.
+
+## Deconvolution
+
+The implementation supports forward and backward data and backward weights
+directions.
+
+* Supported input/output formats: plain formats
+* Supported weights formats: `goiw`, `goihw`, `goidhw`, `oiw`, `oihw`, `oidhw`;
