Today’s Highlights: ruyi fixes cross-repo installation state issue, RuyiSDK 0.53 scheduled for release today

Date: 2026-09-23　Source: fix PR #502, issue #501

At 09:01 Beijing time on 09-23, the ruyi package manager merged “Fix installation state managemet across repos” into the main branch (merge commit 802dd4d9; fix commit 08fd6aeb, developed by maintainer xen0n), closing issue #501 reported by community user qingwan12138 on 09-21: after switching package sources, installed packages showed as “not installed,” and reinstallation was skipped, leaving the state permanently un-updatable.

Issue mechanism: installation records are keyed by “source repo ID,” but install deduplication checks only “name + version.” When a package with the same name and version exists in multiple repos, a user who installs from repo A and then switches to repo B will see ruyi list report “not installed” because it queries by the new repo ID; reinstalling is then short-circuited by “already installed, skipping” (exit code 0) without writing a new repo record; and uninstalling reports “not tracked as installed.” This ultimately creates a deadlock where “files are on disk but state is forever not-installed,” recoverable only via --reinstall or by uninstalling first. The fix changes installation state queries to match across repos by installation identity (category, name, version, host), preferring the exact repo ID record when identities match, and makes uninstall cover all same-identity records for the software, incidentally cleaning up duplicate records left by older --reinstall versions; a total of 162 lines changed, of which 117 are new regression tests (in the two files state.py and test_state.py).

The fix has been written into the issue 077 biweekly draft completed the same day (see 4.1): the draft’s “Package Manager” section states that “RuyiSDK 0.53 will be released on September 24, 2026, with the corresponding package manager version also being 0.53.0,” and lists the same batch of updates including binary package ABI compatibility detection infrastructure, default repo priority fix, and download failure mirror fallback fix. As of the end of the window (09-24 04:30), the latest published Release remains 0.54.0-alpha.20260918, with the v0.53.x branch stopped at 0.53.0-beta.20260917; the official version tagging and release announcement are today’s primary watch points.

1. RuyiAI Stack Progress (PyTorch / Triton / TileLang RISC-V Porting)

Window Overview: Of the 19 repositories in the RuyiAI-Stack organization, 5 saw activity during the window: pytorch (main upstream sync), ruyiai-daily, ruyiai-stack.github.io, mxnet, and caffe (newly created); triton-riscv, tilelang-riscv, llvm-project, pytorch-ci, FBGEMM, cpuinfo, VecIntrinBench, IntrinTrans, harness, dsh-osc, torq-tile, and others saw no pushes during the window.

1.1 PyTorch fork sees no RISC-V feature commits during window: riscv branch silent, 8 open PRs unchanged (09-23 status)

Date: 2026-09-23　Source: riscv branch commits, PR list

The fork’s riscv branch saw no new commits during the window: the branch head remains the 4f173e3e batch (bytes_to_scalar fix, inductor test blocklist, linear cross-entropy ULP tolerance, SyncBots integration, etc., with timestamps frozen on the evening of 09-20); the 8 open merge requests (#23, #35, #36, #38, #43, #46, #48, #51) remain timestamped 09-21 with no new merges and no newly opened PRs during the window. The two pending RVV patches (#46 ATen RVV support, #48 RVV CPU capability) remain unmerged, with wait times continuing to accumulate.

The main branch saw 20 upstream sync commits during the window, covering routine topics (FakeTensor-related rollbacks, MTIA SDPA test gating, CUTLASS tests, MPS histc, ROCm test reuse, xpu Triton pinning, etc.); filtering item by item against keywords such as riscv, rvv, vector, XuanTie, rv64, and rv32 turned up no RISC-V-related content, so this issue does not cover them in detail.

1.2 triton-riscv, tilelang-riscv, and dedicated target repositories silent during window (09-23 status)

Date: 2026-09-23　Source: triton-riscv, tilelang-riscv, llvm-project

The compiler and operator porting line saw no new activity this issue: triton-riscv commits stopped on 09-14, tilelang-riscv on 07-16, and the llvm-project fork on 09-17; harness (09-10), dsh-osc (09-15), and pytorch-ci (08-31) were also silent. None of the above repositories saw commits or releases during the window.

1.3 Tech intelligence repository pushes 09-23 issue, site contributor data auto-updated (09-23 ~ 09-24)

Date: 2026-09-23　Source: commit 4c981090, site data commit 2ef2fadb

The tech intelligence repository completed one commit during the window (Beijing time 09-23 06:20), covering the 09-23 issue, with a self-described rolling window of 09-22 06:00 to 09-23 05:00. The RISC-V section of that issue included: XuanTie Hypervisor test suite refactoring (PR #33, test address translation modes now driven by platform/suite configuration), XiangShan vector floating-point path integration (PR #6615, kunminghu-v3 branch filling in register read/write, wakeup, and bypass data paths between the vector and floating-point regions), the LLVM “software interpreter execution” RISC-V target RFC (interpreter cost model discussion), plus items such as Buildroot external tree inclusion of SyterKit boot builds; most of the above items were originally timestamped before the window, so per the no-duplication principle this issue does not cover them in detail and only records the publishing action. The site repository saw one additional automated commit during the window (Beijing time 09-24 03:26), a routine update of the contributor data file.

1.4 RuyiAI-Stack organization adds two repositories, mxnet and caffe (09-23)

Date: 2026-09-23　Source: RuyiAI-Stack/mxnet, RuyiAI-Stack/caffe

The organization created two repositories in succession on the morning of 09-23 Beijing time (around 09:32 and 09:38): mxnet and caffe, bringing the total number of public repositories to 19. Neither repository is a GitHub fork link, and both carry full upstream history — mxnet contains 43 branches (master, v1.x, v2.0.0.alpha, etc.), with its latest commit stopping in 2023-01; caffe contains 7 branches, with its latest commit stopping in 2020-02; neither repository saw new commits during the window. Combined with the organization’s existing pytorch fork, RuyiAI-Stack’s coverage of classic deep learning frameworks under the “native + ported” approach has been broadened; the specific purpose of the two repositories (archival, porting baseline, or starting point for new work) remains to be tracked in future windows.

II. RuyiSDK Toolchain and Distributions (Kernel, Support Matrix, IDE, openRuyi)

Window Overview: Of the 46 repositories in the ruyisdk organization, 7 had pushes during the window: ruyi (#502 merged), support-matrix (4 merged, 3 under review), wechat-articles (5 pushes), ruyisdk-vscode-extension (3 pushes), ruyisdk-website, ruyi-backend, linux-xuantie-kernel (2 pushes); ruyi-tuner, riscv-gcc, board-docs, packages-index, docs, ruyisdk-overlay, ruyici and others all show their latest activity on 09-22 or earlier.

2.1 XuanTie Kernel Worktree Merges Two Commits: perf annotate Architecture Name Matching and compat UTS Definition Fix (09-23)

Date: 2026-09-23　Source: commit 94494ca6, commit 5eed2594

At 13:16 Beijing time on 09-23, the ruyisdk organization’s XuanTie kernel worktree (linux-xuantie-kernel, linux-6.6.36 branch) merged two fixes in succession: first, “perf annotate: Match the normalized riscv architecture name” (author cp0613) — aligning perf annotate’s RISC-V architecture name matching to the normalized naming convention, fixing the inconsistency between architecture name normalization and matching in the toolchain; second, “riscv: compat: fix COMPAT_UTS_MACHINE definition” (author RevySR) — correcting the COMPAT_UTS_MACHINE macro definition in the compat layer, which concerns the value of the UTS machine name field for 32-bit compatibility processes. The worktree’s previous most recent merge was the T-Head PMA memory type errata patch on 09-20; this period’s two commits are part of continuous small-step maintenance.

2.2 Support Matrix Lands Four Reports: Three Milk-V Duo S Reports and a K510 Update, with Three More PRs Under Review (09-23)

Date: 2026-09-23　Source: PR #407, PR #396, PR #395, PR #392

The support matrix merged four reports in a concentrated batch on the evening of 09-23 (between 20:11 and 21:03 Beijing time): a new xv6 test report for Milk-V Duo S (PR #407), an RT-Thread test report (PR #396), and a Debian test report (PR #395), all three submitted by community contributor ZihanCheng63; plus an update to the K510 BuildRoot test report (PR #392, submitted by zhiyao310). The Duo S report line continues the Arch Linux and Ubuntu entries from around 09-21, with xv6 being a newly added system category. Three PRs remained under review and unmerged at the end of the window: the Duo S Zephyr report (PR #405, last updated 09-24 00:54) and RT-Thread Smart report (PR #397), as well as an RT-Thread 5.3.1 report for the ESP32C3 (Espressif MCU with RISC-V core) (PR #406).

2.3 IDE and Tooling: Three VS Code Extension Fixes, Routine Website Data Update, Backend Dependency Upgrade (09-23)

Date: 2026-09-23　Source: extension commit 72c74a59, extension commit 413db615

The RuyiSDK VS Code extension saw three fixes submitted by maintainer sisungo during the window (around 14:51 Beijing time on 09-23): fixing some versions being incorrectly marked as pre-release, adding error messages for pip installation failures, and updating screenshots to match the new icons. The website repository received one automated API data update (#590); ruyi-backend merged Dependabot’s pydantic 2.13.5 upgrade (PR #122). None of the three involve functional changes; all are routine maintenance.

2.4 openRuyi Merges Two Commits: vkmark Backport Fix and SPDX Header Check; No New Announcements on News Page (09-23)

Date: 2026-09-23　Source: commit ac32afa3, commit f81cb3be

Two commits in the openRuyi package directory during the window: at 16:53 Beijing time, Icenowy Zheng merged a vkmark backport patch (fixing a crash under the lavapipe software rendering scenario); at 11:59, honghua added a check-spdx-header pre-commit check (license header compliance automation). The organization’s ceph-ci repository had 2 additional CI infrastructure adjustments (non-ASan build pool limit set to 24, cleanup tasks). The openRuyi news page had no updates during the window; the latest announcement remains the 2026.08 monthly release, and the 2026.09 release page has not yet gone live.

III. Vector Extensions and Operator Optimization (VecIntrinBench / IntrinTrans / FBGEMM)

3.1 All Three Dedicated Target Repositories Silent During the Window (09-23 Status)

Date: 2026-09-23　Source: VecIntrinBench, IntrinTrans, FBGEMM

All three repositories — targeting vector intrinsic benchmarks, intrinsic translation, and low-precision operator libraries — had no commits during the window: VecIntrinBench’s last commit was 02-13 (latest push record 06-24), IntrinTrans 06-25, and the FBGEMM fork 07-13; fellow observation targets cpuinfo (05-20) and torq-tile (04-09) were likewise silent. The most recent reproducible result in this direction remains the ONNX Runtime MLAS RVV kernel optimization recorded on 09-17 (3.01x speedup on ResNet50 on K3/X100); for tooling-side progress related to vector optimization, see the entries in the LLVM, Go, and V8 sections of the biweekly draft in 4.1.

IV. Community and Events (Biweekly Report, Forum)

4.1 Biweekly Report Issue 077 Completes Integration of Five Sections, Publishing Today (09-23)

Date: 2026-09-23　Source: Commit #359, Commit #364, Issue 077 Draft

Biweekly Report Issue 077 completed five section-level commits within the window (file 20260924-ruyisdk-biweekly-77.md): ruyipkg (#359, 09:17, including the 0.53 update notes and packages-index resource updates), GCC (#360, 11:36), Go (#361, 12:24), OpenJDK (#363, 15:22), and the base C library (#364, 16:24). In terms of content: the base C library section adds coverage of glibc porting pow into the libmvec framework and newlib porting vector math implementations of rsqrt and expm1; the OpenJDK section lists the 11 JDK mainline PRs reviewed and merged in this issue (including fixes for RISC-V string_indexof_char out-of-bounds, G1 barrier optimization, vector integer division, and Zcb extension enabled by default) along with progress on the RISC-V port of JEP 544 AOT static compilation; the Go section documents retesting of chacha20 RVV optimizations and an RVV SIMD proposal for the image library; the GCC section covers backports of Spacemit vendor extensions and more. Issue 077 is scheduled for release today (09-24) and remained in draft integration status as of the end of the window (the latest published issue on the forum is still 076).

4.2 Forum Adds 09-23 Open Source Tech News Roundup Post (09-23)

Date: 2026-09-23　Source: Community Post 2850

One new topic appeared on the forum within the window: at 11:30 Beijing time on 09-23, community member Yaya-tan001 posted “2026-09-23 Open Source Tech News Roundup” (Topic No. 2850) in the RuyiAI section, containing a daily open source news digest. This issue covers the proposed LLVM LLD Massive Binaries working group, Triton’s FP4-to-FP32 upcast support, Spike’s fix for mip.SEIP read/write semantics defects, and items from the PyTorch ecosystem and the AI industry. The post received no replies; there were no other new topics on the forum in this window, nor any new biweekly progress posts. The Ruyi community booth at the Yunqi Conference welcomes the final day of its exhibition today (09-24).

V. Trend Observations

5.1 Release-Week Cadence: Immediate Fix Loop Plus the 0.53 Release and Biweekly Report 077

From report to merge took about 36 hours (#501 was reported on 09-21 at 20:48 and the fix was merged on 09-23 at 09:01), and the maintainer wrote the fix into the 0.53 update notes of the biweekly report about a quarter-hour after the merge — “report, fix, and release artifact” all closed the loop within the same release cycle, a direct sample of the community’s response cadence. Observation points worth checking over the next 24 hours: whether the formal tagging of the v0.53.x branch and the 0.53.0 release announcement appear as expected; and whether the fix lands as a backport in the actual 0.53.0 changelog (the v0.53.x branch currently still sits at 0.53.0-beta.20260917).

5.2 The “Single Board, Multiple Systems” Pattern in the Support Matrix and the Pending Queue

Within three days, the Milk-V Duo S extended from Arch Linux and Ubuntu to Debian, RT-Thread, and xv6, and with Zephyr and RT-Thread Smart still under review, the OS coverage of a single low-cost board is being systematically rolled out; meanwhile, reports for edge and MCU-class chips such as the K510, CH32V307, and ESP32C3 are also being updated on a rolling basis. For users, the density of reproducible material for “check the matrix first, then pick a board” is increasing; for the community, such reports are mostly entry points for new contributors to cut their teeth, and the length of the pending queue reflects contributor activity better than the number of merges in a single day.

5.3 Broadening Framework Coverage and the Wait for Depth on the PyTorch Side

RuyiAI-Stack has newly added mxnet and caffe to its repositories (see 1.4), placing them alongside the existing pytorch fork to form three classic deep learning frameworks side by side; but the RISC-V feature line of the PyTorch fork remains silent (no new commits on the riscv branch, the timestamps of 8 open PRs unmoved, and the two RVV kernel support patches still queued). Breadth expansion and depth advancement have diverged, and the first actions in the mxnet and caffe repos can be used to verify where this “broad but shallow” interim state heads next.

5.4 Gaps and Watch Points in This Window

Gaps that must be recorded faithfully: the PyTorch riscv branch and its open PRs are both silent; the three dedicated target repositories triton-riscv, tilelang-riscv, and the vector operator project are all silent; ruyi-tuner, riscv-gcc, board-docs, and packages-index have no commits or releases; on the news side, multiple Google News queries in both Chinese and English for RuyiAI, RuyiSDK, the Ruyi community, and openRuyi returned zero hits in a row, and there were no new arXiv entries within the window. Watch points: first, the formal release of RuyiSDK 0.53 and ruyi 0.53.0 and the tagging of v0.53.x; second, the content of the official biweekly report 077; third, closing developments from the Yunqi Conference (through 09-24); fourth, follow-up actions in the mxnet and caffe repos; fifth, the openRuyi 2026.09 monthly release announcement.
