[miopen] Enable long path support for addkernels on Windows - #7387
Merged
Merged
Conversation
Add a Windows application manifest to addkernels.exe that enables long path support (paths > 260 characters). This fixes build failures on Windows when MIOpen kernel source paths exceed MAX_PATH. The manifest sets longPathAware=true, which combined with the system LongPathsEnabled registry setting allows the executable to handle paths up to 32,767 characters.

Nice!! I didn't know this was possible so thanks for the PR. will ensure CI is good and then we'll get it merged since risk seems low. |

That is pretty nifty.

Previously for gfx1151 MIOpen builds in rocm-libraries multi arch CI, we kept getting errors for `[MIOpen] File not found: "C:/home/runner/_work/rocm-libraries/rocm-libraries/external-rocm-libraries/projects/miopen/src/kernels/dynamic_igemm/igemm_gtc_xdlops_nhwc_gfx940/bwd_fp32/igemm_bwd_gtcx3_nhwc_fp32_bx0_ex1_bt64x32x32_wt16x16x4_ws1x1_wr2x1_ta1x4x2x1_1x8x1x32_tb1x4x1x1_1x8x1x32_mh_gkgs.s"` from https://github.com/ROCm/rocm-libraries/actions/runs/25721249175/job/75551278686, as the path exceeded 260 characters.

JIRA ID: ALMIOPEN-2312 ## Motivation `projects/miopen/CHANGELOG.md`'s "MIOpen 3.5.2 for ROCm 7.14.0" section only had 4 entries, but 68 commits touched `projects/miopen` between the `therock-7.13` tag and `release/therock-7.14`. Auditing that commit range (via `git log --oneline therock-7.13..remotes/origin/release/therock-7.14 -- projects/miopen`) found 18 additional user-facing changes — new gfx950/gfx1250 architecture support, SystemDB refreshes, AI-heuristic improvements, several correctness/crash bug fixes, and OpenCL solver removals — that were never documented. This PR backfills those entries so the 7.14.0 changelog accurately reflects what shipped. ## Technical Details Added 24 lines to the existing "MIOpen 3.5.2 for ROCm 7.14.0" section of `projects/miopen/CHANGELOG.md`, merging new bullets into the existing `Added`/`Changed`/`Resolved Issues` sub-sections (no new entries were duplicated or reworded) and adding a new `Removed` sub-section for solver removals. No existing content was altered. Each new bullet was traced to a specific commit + PR: | Entry | Commit | PR | |---|---|---| | Added gfx950 (MI350X/MI355X) SystemDB | `60d8e1e5175` | #8081 | | Added initial gfx1250 architecture support | `d3f057b2f22` | #7587 | | Added JSON-formatted performance logs (`MIOPEN_PERFORMANCE_LOGS`) | `ffbde871260` | #5736 | | Refreshed gfx942 SystemDB | `faf754a9ef6` | #8174 | | Refined 2D AI heuristics (Tunanet/KTN) for gfx942 & gfx950 | `c24ad415884` | #7109 | | Fixed thread-safety issue in AI-heuristic model caches | `cd957402309` | #9149 (cherry-pick of #9131) | | Fixed CK grouped-conv solvers not always registered in host | `c971d54d7ae` | #9105 | | Fixed legacy CK buffer resource descriptor (gfx1250) | `1dee011b8b0` | #8758 | | Removed stale gfx942 SystemDB naive-solver entries | `f42668f6316` | #7028 | | Fixed softmax NaN when `beta=0` | `fb8157c8512` | #8426 | | Fixed BN backward spatial variant 1 vectorized memory access bug | `1351a7e8b10` | #6765 | | Fixed use-after-free of `kernel_id` in `InitInvokerFactoryNCHW` | `394ebffb50d` | #7922 | | Fixed SoftMarginLoss forward reduce-kernel kernarg corruption | `1e65a31570f` | #8065, #8135 | | Fixed build with `MIOPEN_ENABLE_AI_KERNEL_TUNING=OFF` | `e6288c3ca61` | #6800 | | Fixed install RPATH for MIOpenDriver / CK backend libs | `ef8a4cf2f93` | #7485 | | Fixed dangling lambda causing log-level 6 segfault | `190f9791737` | #6953 | | Enabled Windows long-path support for `addkernels` | `1f9d69724cf` | #7387 | | Removed OCL solver `ConvOclDirectFwd1x1` | `126c720cadd` | #6491 | | Removed OCL solver `conv_ocl_dir2Dfwdgen` | `2d499ddf709` | #6633 | | Removed OCL solvers `ConvOclBwdWrW1x1`, `ConvOclBwdWrW2` | `b5d43a33dc6` | #6859 | | Removed OCL solvers `OpTensorLeadingOnes`, `Op5dTensorGeneric` | `8642c83b7de` | #7347 | The remaining ~40 commits in the 68-commit range were deliberately excluded (tests/CI/build/docs/internal refactors/1:1 OCL→HIP swaps with no behavior change, per each commit's own stated scope) and are not represented here. ## Risk Assessment **Risk Level: 🟢 Low** This is a documentation-only change to a single Markdown file. No code, build configuration, tests, or public API surface is touched. ### Impacted Components - `projects/miopen/CHANGELOG.md` only. ### Potential Side Effects None expected. This does not change any runtime behavior; it only documents changes that already shipped on `release/therock-7.14`. ### Mitigation Steps None required beyond normal review — a reviewer familiar with the 7.14 release can spot-check a few entries against the linked commit hashes/PR numbers for accuracy. ## Test Plan Not applicable (no code changes). Verification was done by cross-referencing every added bullet against a specific commit hash and PR number pulled from `git log`, and by diffing the edited section against `git show remotes/origin/release/therock-7.14:projects/miopen/CHANGELOG.md` to confirm no existing entry was duplicated or altered. ## Test Result All 21 new bullets map 1:1 to a real commit/PR in the `therock-7.13..release/therock-7.14` range for `projects/miopen`. No pre-existing changelog text was modified — `git diff` shows a pure addition (24 insertions, 0 deletions). Two borderline commits (`a67834413e8` "Standalone build", `7c7cd5774a9` "enable warnings about deprecated API/features") were deliberately left out pending author judgment on whether they warrant an entry.
