[CK Tile] Add WAVELET pipeline for forward grouped
convolution (#8009)
## Motivation
CK Tile forward grouped convolution trails classic CK on 3x3
convolutions whose
output-channel count is not divisible by 8, where the narrow output
store limits
the compute CShuffle epilogue. This ports the WAVELET pipeline (added
for
backward-weight in #7937) to the forward kernel to close that gap.
## Technical Details
- Kernel (`grouped_convolution_forward_kernel.hpp`): WAVELET
load/math-wave wiring,
mirroring the backward-weight implementation; the non-WAVELET path is
unchanged.
- Generator: implement `parse_native_fwd_instance`, the forward
native-instance parser.
- Registered WAVELET instances: profiler bf16 3 / fp16 5, tests 1 each.
WAVELET requires input channels divisible by 8 (it does not apply to
depthwise).
The bf16/fp16 instance asymmetry is intentional and measured: the VecC=8
tiles
never beat the compute pool in bf16 but win about 20% of divisible-by-8
3x3 shapes
in fp16, so VecC=8 is registered for fp16 only.
## Test Plan
- Correctness (CPU reference) for every registered profiler instance,
across VecC variants.
- Per-shape best-instance performance sweep over the 34 RetinaNet shapes
(bf16) and
a 200-shape cross-model sweep (bf16 and fp16), compared against classic
CK.
## Test Result
- Correctness: PASS for all instances.
- RetinaNet (bf16, vs classic CK): faster on 28 of 34 shapes, geomean
+19.5%; the
not-divisible-by-8 shapes up to 3.7x. One 1x1 stride-2 shape stays ~20%
behind
classic CK, unrelated to WAVELET.
- Cross-model (200 shapes): WAVELET wins 3x3 not-divisible-by-8 in both
dtypes
(up to 61% over the next-best compute instance); for divisible-by-8 3x3
it wins
about 20% of shapes in fp16 (3-11%) and none in bf16.

[CK Tile] Add conv Wavelet GEMM pipeline and bwd_weight
instances (#7937)
## Motivation
CK Tile had no pipeline competitive with old CK's wavelet on the
RetinaNet K=36 C=256 3x3 conv bwd_weight class. This adds a
wave-specialized "wavelet" GEMM pipeline so CK Tile has a competitive
kernel for spatial small-K shapes.
## Technical Details
- New wavelet GEMM pipeline (`gemm_pipeline_ag_bg_cr_wavelet.hpp`):
workgroup split into math waves (LDS read + MFMA) and load waves (DRAM
read + LDS write).
- VGPR role-split: `operator()` has two top-level mutually-exclusive
`is_math` branches so the allocator overlays both roles onto the same
physical VGPRs, cutting arch VGPR ~33-40% and raising occupancy.
Correctness depends on identical `block_sync_lds` counts on both arms
plus a matching load-wave barrier stub in the epilogue
(`cshuffle_epilogue.hpp`).
- Kernel dispatch (`grouped_convolution_backward_weight_kernel.hpp`):
`kIsWavelet` path, `LaunchBlockSize`, load-wave barrier stub.
Uplift: wavelet is the fastest CK Tile pipeline on the RetinaNet K=36
C=256 3x3 family, beating the best non-wavelet CK Tile kernel by 10-27%
(googlenet K=320 by 16-23%); the role-split roughly halves the parity
gap vs old CK on the 13x13 fp16 shape.
## Test Plan
- `ckProfiler grouped_conv_bwd_weight`, NHWGC layout, fp16/bf16,
`split_k=all`, CPU verify on RetinaNet K=36 shapes (7x7, 13x13) and a
broad 2D sweep.
- Correctness: `-v=1` across `split_k` in {-1,1,2,4,8,16,32,64}
(barrier-parity / deadlock check).
- `test_grouped_convnd_bwd_weight` over the tests `.conf` wavelet
instances.
## Test Result
- All wavelet instances CPU-verify correct across the split-K sweep; no
hangs (dual-arm barrier sequence matches).
- Wavelet wins the RetinaNet K=36 C=256 3x3 family (10-27% over best
non-wavelet CK Tile) and googlenet K=320 (16-23%); at parity-or-better
vs old CK on the majority of spatial shapes.

[CK_TILE] Add depthwise conv2d forward kernel (FP16/FP32) (#6838)
## Motivation
CK currently has no kernel optimized for depthwise convolution
(G=C_in=C_out, C=K=1 per group) and existing generic paths perform
poorly for this workload. This PR adds a dedicated depthwise conv
forward kernel in CK Tile.
## Technical Details
Adds a dedicated depthwise conv2d forward op to CK Tile that performs
direct convolution rather than falling back to the generic GEMM path.
The kernel is templatized by filter size, stride, and data type, and
compiled into ~60 instances covering common configurations (kernel
3/5/7/9, stride 1/2, FP16/FP32). Supports both CDNA (gfx942/gfx950) and
RDNA (gfx1100/gfx1200) architectures.
## Test Plan
- [x] Correctness and performance validated on gfx942, gfx950, and
gfx1100, with ckProfiler `grouped_conv_fwd` as baseline.
- [ ] MI300A (gfx942) and gfx1200 validation.

[CK_TILE, CK_BUILDER] Add bwd data to CK Tile profiler (#5516)
## Motivation
We want close the performance gap between old CK and CK Tile for bwd
data convolutions. To achieve this, we need tow things
- Configurations for the old CK kernel instances such that we can map
them into CK Tile instances.
- Support in CK profiler to run the CK Tile instance with the same API
as for old CK instances.
## Technical Details
Extracted kernel configurations from old CK. The codegen python script
for CK Tile convs is extended to support also bwd data. The generated
instances are added to the CMake build (target
`device_grouped_conv_bwd_data_tile_instances`).
A new profiler op (`grouped_conv_bwd_data_tile`) has been added to the
CK Profiler. The API is same as for old CK's profiler op
`grouped_conv_bwd_data`.

[CK_TILE] Add CK Tile bwd weight profiler (#4797)
## Motivation
To compare old CK and CK Tile, we need to extend the current CK profiler
to support running also CK Tile instance with the same API. In order to
have the same instance coverage in CK Tile compared to the old CK, I've
added code generation from old CK configurations to CK Tile instances
using the CK Builder.
## Technical Details
- The codegen python script for CK Tile fwd convs is extended to support
also bwd weight and bwd data.
- The generated instances are added to the CMake build (target
`device_grouped_conv_bwd_weight_tile_instance`s).
- A new profiler op (`grouped_conv_bwd_weight_tile`) has been added to
the CK Profiler.

[CK_TILE] Add support and tests for V6 pipeline in conv fwd
(#4357)
Added support for conv v6 pipeline in ck tile's convolution forward
kernel. CK Tile v6 pipeline is the equivalent to old ck's V5 pipeline
and should be faster than other pipelines for some cases. This PR also
adds tests inside profiler that's currently inside experimental
directory, so now we should be able to detect regressions easier.
