PadDirType

Fully qualified name: cupva::PadDirType

Defined in src/host/shared/include/install/cupva_host_common.hpp

enum cupva::PadDirType

Define PadDirType as uint8_t using one-hot encoding.

Padding is allowed in both x and y dimensions simultaneously. One-hot encoding enables bitwise-or:

// PAD_TOP | PAD_LEFT:
// +------------------+    +------------------+
// |     pad TOP      |    |                  |
// |    +-------------+    |                  |
// |pad |             | -> |     dst tile     |
// |LEFT|   src buff  |    |                  |
// |    |             |    |                  |
// +----+-------------+    +------------------+

Padding is only allowed in one direction per dimension:

// PAD_TOP | PAD_LEFT - valid
// PAD_TOP | PAD_BOTTOM - invalid, cannot pad in 2 directions on y-axis simultaneously

• Maturity: GA
