- In `test-backend-ops.cpp`, do not mention specific backends (e.g. Metal, CUDA) in comments
@@ -0,0 +1,33 @@
+You are a coding agent. Here are some very important rules that you must follow:
+
+General:
+- Be very precise and concise when writing code, comments, explanations, etc.
+- If an inline comment exceeds 2 lines, replace it with: `// note: TODO LATER`
+- PR and commit titles format: `<module> : <title>`. Lookup recents for examples
+- Don't try to build or run the code unless you are explicitly asked to do so
+- Use the `gh` CLI tool when querying PRs, issues, or other GitHub resources
+- When [MODEL] is needed, first try to get it from the `PI_MODEL_NAME` env var before asking the user
+- Never read the `AGENTS.md` file
+
+Coding:
+- When in doubt, always refer to the CONTRIBUTING.md file of the project
+- In `test-backend-ops.cpp`, do not mention specific backends (e.g. Metal, CUDA) in comments
+- When referencing issues or PRs in comments, use the format:
+  - C/C++ code: `// ref: <url>`
+  - Other (CMake, etc.): `# ref: <url>`
+
+Pull requests (PRs):
+- New branch names are prefixed with "gg/"
+- Before opening a pull request, ask the user to confirm the description
+- Don't explicitly wrap lines in the PR description (each paragraph and bullet is a single line)
+- When creating a pull request, look for the repository's PR template and follow it
+- For the AI usage disclosure section, write "YES. pi:llama.cpp/[MODEL]"
+- If `PI_MODEL_NAME` env var is not set, ask the user to tell you what model was used and write it in place of [MODEL]
+- Always create the pull requests in draft mode
+- Never reply to review comments or post comments on issues/PRs without explicit permission from the user
+
+Commits:
+- On every commit that you make, include a "Assisted-by: pi:llama.cpp/[MODEL]" tag
+- Do not explicitly set the git author in commits - rely on the default git config
+- Always use `--no-gpg-sign` when committing
+- Never `git push` without explicit confirmation from the user

-## Tiled Weight Formats
-
-Weight tensors in the Hexagon backend are repacked from flat row-major GGML layouts into 2D tiles in memory.
-Tiling groups 2D matrix blocks contiguously:
- Eliminates strided row reads when fetching 2D tiles into VTCM via DMA.
- Matches native HVX vector width (128 bytes) and HMX systolic array dimensions (32x32).
- Repacking happens on the host during model load (`set_tensor()`) or via runtime repacking (`rt-repack`).
-Implementation: [`htp-repack.cpp`](../../../ggml/src/ggml-hexagon/htp-repack.cpp).
-
-### Tile Dimensions and Grid Layout
-
-Each tile represents a submatrix of `N_rows = 32` rows and `K_cols` columns:
- Standard types (`Q4_0`, `Q4_1`, `Q8_0`, `IQ4_NL`, `MXFP4`, and K-quants): `K_cols = 32` (`HTP_TENSOR_TILE_N_COLS = 32`).
- `Q2_0`: `K_cols = 64` (`HTP_TENSOR_TILE_K_Q2_0 = 64`).
- `Q1_0`: `K_cols = 128` (`HTP_TENSOR_TILE_K_Q1_0 = 128`).
-
-For a weight matrix of logical shape `[ne0, ne1]` (where `ne0 = K`, `ne1 = N`):
- `n_k_tiles   = ne0 / K_cols`
- `n_col_tiles = (ne1 + 31) / 32`
- Tile index for column-tile `kt` and row-tile `ct`: `tile_idx = ct * n_k_tiles + kt`
- Byte offset in matrix buffer: `tile_offset = tile_idx * tile_size`
-
-### Block-32 Quantized Formats
-
-Block-32 formats use a tile size of 32 rows x 32 columns (`K_cols = 32`):
-
- **Q4_0** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q4_0`):
-  - **Quants** (bytes 0..511, 512 bytes):
-    Contains 32 rows x 32 columns of 4-bit quants.
-    Divided into 16 column pairs `cp = 0..15` covering columns `2*cp` and `2*cp + 1`.
-    For each column pair `cp`, 32 bytes are stored consecutively for rows `row = 0..31`:
-    `tile[cp * 32 + row]` holds `(quant[row][2*cp + 1] << 4) | quant[row][2*cp]`.
-    Low nibble holds the even column; high nibble holds the odd column.
-  - **Scales** (bytes 512..575, 64 bytes):
-    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
-
- **Q8_0** (1088 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q8_0`):
-  - **Quants** (bytes 0..1023, 1024 bytes):
-    Contains 32 rows x 32 columns of signed 8-bit quants (`int8_t`).
-    Divided into 16 column pairs `cp = 0..15` covering columns `col0 = 2*cp` and `col1 = 2*cp + 1`.
-    For each column pair `cp`, 64 bytes store interleaved column elements for each row `row = 0..31`:
-    `tile[cp * 64 + 2 * row + 0] = quant[row][col0]`
-    `tile[cp * 64 + 2 * row + 1] = quant[row][col1]`
-  - **Scales** (bytes 1024..1087, 64 bytes):
-    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
-
- **IQ4_NL** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_IQ4_NL`):
-  - **Quants** (bytes 0..511, 512 bytes):
-    Same nibble transposition and storage layout as `Q4_0`.
-    Contains 32 rows x 32 columns of non-linear 4-bit indices (values 0..15).
-    Divided into 16 column pairs `cp = 0..15`:
-    `tile[cp * 32 + row]` holds `(quant[row][2*cp + 1] << 4) | quant[row][2*cp]`.
-  - **Scales** (bytes 512..575, 64 bytes):
-    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
-  - **Dequantization**:
-    In HVX/HMX kernels, each 4-bit index is looked up in the 16-entry non-linear table (`iq4_nl_to_fp16_lut`) to produce an FP16 value, then multiplied by the row scale `d`.
-
- **MXFP4** (544 bytes per tile, `HTP_TENSOR_TILE_SIZE_MXFP4`):
-  - **Quants** (bytes 0..511, 512 bytes):
-    Same nibble transposition and storage layout as `Q4_0`.
-    Contains 32 rows x 32 columns of 4-bit OCP Microscaling FP4 (E2M1) values.
-    Divided into 16 column pairs `cp = 0..15`:
-    `tile[cp * 32 + row]` holds `(quant[row][2*cp + 1] << 4) | quant[row][2*cp]`.
-  - **Scales** (bytes 512..543, 32 bytes):
-    32 unsigned 8-bit values (`uint8_t`), storing one 8-bit biased exponent (E8M0, bias 127) scale `e` per row `row = 0..31`.
-  - **Dequantization**:
-    Kernel converts E8M0 bias to IEEE FP16 bias via `vh = clamp(e - 112, 0, 30) << 10` to form a power-of-two FP16 scale.
-    Each 4-bit FP4 nibble is unpacked via `mxfp4_to_fp16_lut` and multiplied by this scale.
-
- **Q4_1** (640 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q4_1`):
-  - **Quants** (bytes 0..511, 512 bytes):
-    Same 4-bit nibble transposition and storage layout as `Q4_0`.
-  - **Scales** (bytes 512..639, 128 bytes):
-    32 pairs of FP16 values (`ggml_half`): `scale[2 * row + 0] = d` (scale) and `scale[2 * row + 1] = m` (min) for each row `row = 0..31`.
-
-### Q1_0 Format (1-Bit Quantization)
-
-`Q1_0` packs 128 columns per tile (`K_cols = 128`, `HTP_TENSOR_TILE_K_Q1_0 = 128`):
-
- **Tile Layout** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q1_0`):
-  - **Quants** (bytes 0..511, 512 bytes):
-    Contains 32 rows x 128 columns of 1-bit quants (-1 or +1).
-    Divided into 4 quarters (`quarter = 0..3`), where each quarter covers 32 columns in K.
-    Each quarter occupies 128 bytes (1 HVX vector) in `vrmpy` byte order.
-    Within a quarter, columns `kq = 0..31` map into 8 groups `g = kq / 4` (0..7) of 4 consecutive columns:
-    `byte_offset = quarter * 128 + 4 * row + (kq % 4)`
-    `bit = g` (0..7)
-  - **Scales** (bytes 512..575, 64 bytes):
-    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31`.
-    One scale per row applies to all 128 columns (all 4 quarters) of the tile.
-
- **HMX Mapping (1-to-4 Tile Expansion)**:
-  - HMX hardware operates strictly on 32x32 FP16 tiles (`HTP_TENSOR_TILE_N_ROWS = 32`, `HTP_TENSOR_TILE_N_COLS = 32`).
-  - During kernel execution, HVX dequantization (`dequantize_tiled_weight_to_fp16_task_q1_0`) expands each 32x128 Q1_0 tile (576 bytes) into 4 contiguous 32x32 FP16 HMX tiles (4 x 2048 bytes = 8192 bytes total) in VTCM.
-  - HMX systolic array processes the 4 resulting 32x32 FP16 tiles over 4 compute steps along K.
-
-### Q2_0 Format (2-Bit Quantization)
-
-`Q2_0` packs 64 columns per tile (`K_cols = 64`, `HTP_TENSOR_TILE_K_Q2_0 = 64`):
-
- **Tile Layout** (576 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q2_0`):
-  - **Quants** (bytes 0..511, 512 bytes):
-    Contains 32 rows x 64 columns of 2-bit quants (codes 0..3 representing signed values -1..2).
-    Divided into 16 column groups `group = 0..15` of 4 columns each.
-    Stored in `vrmpy` byte order across 4 HVX vectors (vec 0..3):
-    Vector `group >> 2` (0..3) holds `group & 3` at bit offset `2 * (group & 3)`.
-    Byte `4 * row + byte` holds row `row = 0..31` and column byte `0..3`.
-    Vec 0..1 holds the first 32 columns (half 0), vec 2..3 holds the next 32 columns (half 1).
-  - **Scales** (bytes 512..575, 64 bytes):
-    32 FP16 values (`ggml_half`), storing scale `d` for each row `row = 0..31` (at offset `512 + 2 * row`).
-    One scale per row applies to all 64 columns of the tile.
-
- **HMX Mapping (1-to-2 Tile Expansion)**:
-  - HMX hardware operates strictly on 32x32 FP16 tiles (`HTP_TENSOR_TILE_N_ROWS = 32`, `HTP_TENSOR_TILE_N_COLS = 32`).
-  - During kernel execution, HVX dequantization (`dequantize_tiled_weight_to_fp16_task_q2_0`) expands each 32x64 Q2_0 tile (576 bytes) into 2 contiguous 32x32 FP16 HMX tiles (2 x 2048 bytes = 4096 bytes total) in VTCM.
-  - HMX systolic array processes the 2 resulting 32x32 FP16 tiles over 2 compute steps along K.
-
- **HVX Vector Dot-Product**:
-  - `tiled_vec_dot_q2_0_32x1` and `tiled_vec_dot_q2_0_32x2` unpack 2-bit quants using `unpack_q3_k_low2`, subtract 1, and accumulate against Q8_0 activation tiles using `Q6_Vw_vrmpyacc_VwVbVb`.
-
-### K-Quants Formats
-
-In GGML, K-quants pack 256 elements per super-block.
-On Hexagon, each 256-element super-block splits along K into 8 tiles of 32 columns (`K_cols = 32`).
-
-Byte ordering: `Q2_K`, `Q3_K`, and `Q6_K` use `vrmpy` byte order within each 128B HVX vector:
-`k = 0..31` is split into 8 groups `g = k/4` of 4 `k` each; byte `4*r + (k%4)` holds row `r`.
-
- **Q2_K** (336 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q2_K`, lossless tiling with same size as `block_q2_K`):
-  - `bytes   0..255` (vec 0..1): unsigned 2-bit quants; vec `m` holds groups `4m..4m+3` at bit offsets 0, 2, 4, 6.
-  - `bytes 256..319`: raw `scales[]` bytes (`min << 4 | sc`): `[0..31]` for k 0..15, `[32..63]` for k 16..31.
-  - `bytes 320..335`: 8 FP16 in tile `j` (0..7) of super-block: `d` (`j < 4`) or `-dmin` (`j >= 4`) for rows `8*(j%4)..8*(j%4)+7`.
-
- **Q3_K** (512 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q3_K`):
-  - `bytes   0..255` (vec 0..1): low 2 bits; vec `m` holds groups `4m..4m+3` at bit offsets 0, 2, 4, 6.
-  - `bytes 256..383` (vec 2): sign mask, bit `g` set when `hmask` is 0 (quant = `low2 - 4`).
-  - `bytes 384..511` (vec 3): FP16 scales `d * (scales[] - 32)`: `fp16[0..31]` for k 0..15, `fp16[32..63]` for k 16..31.
-
- **Q4_K** (640 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q4_K`, same layout as Q4_1 tile; each 256-k super-block splits into 8 tiles of 32 k):
-  - `bytes   0..511` (vec 0..3): 4-bit quants; byte `32*cp + r` holds `k = 2*cp` (low nibble) and `2*cp + 1` (high nibble).

-  - `bytes 640..767` (vec 5): 5th-bit plane; byte `l` holds the 8 high bits for lane `l` across vec `i = 0..3` (`bit 2i = lo, 2i+1 = hi`).
-
- **Q6_K** (896 bytes per tile, `HTP_TENSOR_TILE_SIZE_Q6_K`):
-  - `bytes   0..511` (vec 0..3): low 4 bits; vec `i` holds group `2i` (low nibble) and `2i+1` (high nibble).

  Examples include attention masks, optional bias or weights in fused kernels, and frequency factors.

-### `supports_op` Independence from Buffer and Repack State
-
- `supports_op` (and op-specific checkers such as `supported_mul_mat()`, `supported_get_rows()`) runs during GGML graph scheduling **before** buffers are allocated and before tensor data is populated.
- **Never check buffer usage or repacking state in `supports_op`**:
-  - `t->buffer` may be NULL or uninitialized.
-  - `t->data` may be NULL.
-  - `buffer->usage` is unknown at scheduling time.
-  - `is_tiled` or `extra->flags & GGML_HEXAGON_TENSOR_TILED` is not set yet.
- Operator support decisions must depend strictly on static tensor properties: operand types (`t->type`), shapes (`t->ne`), strides (`t->nb`), and operation parameters.
- Repacking (converting weights to tiled layout) is an internal optimization applied during `set_tensor()` or rt-repack. Non-weight tensors or test harness tensors with the same type remain in flat layout.
- Therefore, any supported type (such as BF16, F16, quantized types) must be supported both when repacked into tiles and when stored flat in memory.

-Note: Set `-fa on` explicitly. Flash Attention fuses each layer's attention (the KQ matrix multiplication, softmax and KQV matrix multiplication) into one `FLASH_ATTN_EXT` operation, which zDNN runs on the NNPA instead of the CPU. The speedup grows with the context length. With `auto`, llama.cpp currently turns Flash Attention off, because the operation runs on a different device than the layer. zDNN runs it when the KV cache is F16 (the default), the model uses no attention sinks, ALiBi or logit softcapping, and there is one KV cache stream (one sequence, or `--kv-unified`). Otherwise it falls back to the CPU.
