Device would write status blocks to wrong addr. - Fix kExclusiveLogin bit: 0x2000 (bit 13 per SBP-2 Table 14), not 0x0020. - Add RemoteWriteCallback to AddressSpaceManager so SBP2LoginSession gets notified when device writes status blocks to its address space. - Fix login response read timing: OnLoginWriteComplete now only ACKs the management agent write and waits for the status block callback instead of immediately reading the login response (which is empty at that point). New OnStatusBlockRemoteWrite dispatches to state-specific handlers. - Wire SubmitDelayedCallback to IODispatchQueue (DispatchAsync + IOSleep pattern matching BusResetCoordinator), replacing the no-op placeholder. --- .../Protocols/SBP2/AddressSpaceManager.hpp | 50 ++- .../Protocols/SBP2/SBP2LoginSession.cpp | 401 +++++++++++------- .../Protocols/SBP2/SBP2LoginSession.hpp | 41 +- ASFWDriver/Protocols/SBP2/SBP2WireFormats.hpp | 2 +- 4 files changed, 321 insertions(+), 173 deletions(-) diff --git a/ASFWDriver/Protocols/SBP2/AddressSpaceManager.hpp b/ASFWDriver/Protocols/SBP2/AddressSpaceManager.hpp index c065ce42..93e2b688 100644 --- a/ASFWDriver/Protocols/SBP2/AddressSpaceManager.hpp +++ b/ASFWDriver/Protocols/SBP2/AddressSpaceManager.hpp @@ -8,6 +8,7 @@ #include #include #include +#include #ifdef ASFW_HOST_TEST #include "../../Testing/HostDriverKitStubs.hpp" @@ -22,6 +23,11 @@ namespace ASFW::Protocols::SBP2 { class AddressSpaceManager { public: + // Callback invoked when a remote write arrives for a registered range. + // Parameters: handle, offset within range, payload data. + using RemoteWriteCallback = std::function payload)>; struct AddressRangeMeta { uint64_t handle{0}; uint64_t address{0}; @@ -197,16 +203,30 @@ class AddressSpaceManager { return Async::ResponseCode::AddressError; } - IOLockLock(lock_); - auto* range = FindRangeByAddressLocked(address, static_cast(payload.size())); - if (!range) { + RemoteWriteCallback callback; + uint64_t handle = 0; + uint32_t offset = 0; + + { + IOLockLock(lock_); + auto* range = FindRangeByAddressLocked(address, static_cast(payload.size())); + if (!range) { + IOLockUnlock(lock_); + return Async::ResponseCode::AddressError; + } + + offset = static_cast(address - range->meta.address); + WriteBytesLocked(*range, offset, payload); + callback = range->onRemoteWrite; + handle = range->meta.handle; IOLockUnlock(lock_); - return Async::ResponseCode::AddressError; } - const uint32_t offset = static_cast(address - range->meta.address); - WriteBytesLocked(*range, offset, payload); - IOLockUnlock(lock_); + // Fire callback outside lock to avoid deadlock. + if (callback) { + callback(handle, offset, payload); + } + return Async::ResponseCode::Complete; } @@ -281,6 +301,21 @@ class AddressSpaceManager { IOLockUnlock(lock_); } + // Register a callback to fire when a remote write arrives for the given handle. + // Must be called after AllocateAddressRange.

-**Entry**: From R1: Reset Wait when bus reset complete - -**State Actions**: `tree_ID_startActions()` - -**Behavior**: -- When PARENT_NOTIFY is observed on a port, that port is marked as a **child port** - -**Exit Transitions**: - -1. **T0:T1** - Timeout or Force Root: - ``` - Condition: (forceRoot || arbTimer >= FORCE_ROOT_TIMEOUT) && - children == NPORT - ``` - - If loop of active ports exists on bus → configuration timeout occurs - - Sets `T0_timeout` flag - - All active ports in Beta mode forced back to P11: Untested state - - May directly result in bus initialization completion - - May allow loop-free build process to set appropriate Beta ports into P12: Loop Disabled state - - Allows fresh bus reset to complete - -2. **T0:T0** - Configuration Timeout Loop: - ``` - Condition: T0_timeout && arbTimer == configTimeout - Action: loop = 1 - PH_EVENT.indication(PH_CONFIG_TIMEOUT, 0, 0) -

---- - -#### T1: Child Handshake - -**Purpose**: All ports labeled as child ports transmit CHILD_NOTIFY signal - -**State Actions**: `childHandshakeActions()` - -**Behavior**: -- Receipt of CHILD_NOTIFY signal allows nodes attached to this node's child port(s) to transition from T2: Parent Handshake to S0: Self-ID Start -- **Leaf nodes** have no children → exit immediately via T1:T2 transition -- If all ports are labeled child ports → node knows it is the **root** -

---- - -#### T3: Root Contention - -**Purpose**: Handle root contention when two nodes both try to make each other the parent - -**State Actions**: `rootContendActions()` - -**Behavior**: -- Both nodes back off by sending IDLE signal, starting a timer, and picking a random bit -- If random bit is one, node waits longer than if zero -- When timer expires, node samples contention port once again - -**Exit Transitions**: - -1. **T3:T2** - Lost contention (become child): - ``` - Condition: portRArb[contention port] == IDLE at end of delay - Action: Send PARENT_NOTIFY signal - ``` - - If node took longer delay, it takes this path - - Allows node to exit T2: Parent Handshake state via Self-ID Start path - - Otherwise two nodes see ROOT_CONTENTION again and repeat process with new random bits - -2. **T3:T1** - Won contention (become root): - ``` - Condition: portRArb[contention port] == PARENT_NOTIFY at end of delay - Action: Other node already transitioned to T2: Parent Handshake - First node returns to T1: Child Handshake and becomes root -

-Bus reset and self-identification are the foundational synchronization mechanisms in IEEE 1394, providing: - -1. **Topology Discovery**: Self-ID state machine broadcasts physical capabilities in deterministic order -2. **Node Addressing**: Distributed tree identification assigns unique physical IDs (0 to N-1) -3. **Speed Negotiation**: Parent-child speed capability exchange during S3/S4 states -4. **Bus Optimization**: Gap count optimization and root forcing improve performance -5. **Error Recovery**: Timeout mechanisms (R1:R0, All:R0c) ensure forward progress - -**State Machine Progression**: -``` -Power-On → R0: Reset Start → R1: Reset Wait → T0-T2: Tree ID → -S0-S4: Self-ID → A0: Idle (Normal Operation) -``` - -**Key Principle**: Distributed state machines where all nodes cooperate to establish coherent topology without centralized coordination. - -**Implementation Complexity**: Requires precise OHCI register sequencing, DMA management, FSM coordination, and sub-microsecond timing for speed signal exchange. - -**Performance Impact**: -- Gap count optimization: 8x bandwidth improvement in typical topologies -- Speed negotiation: Enables S100/S200/S400/S800 operation per link -- Self-ID overhead: ~50-200μs for typical 3-10 node networks -

Use std::atomic with relaxed ordering to avoid undefined behavior while the existing generation counter handles logical synchronization.

写操作可能需要特殊的 AT 描述符配置 -4. **DMA 一致性**：大数据传输时需确保页表映射的 DMA 缓冲区与 OHCI 硬件一致 -5. **DriverKit 沙箱限制**：DriverKit 环境下某些内核级操作（如 IOMemoryDescriptor 操作）有额外约束 -6. **测试覆盖缺口**：LoginSession、CommandORB、ManagementORB、PageTable 目前缺少单元测试（代码量大但未测试） -7. **UserClient API 缺口**：阶段三和四的核心逻辑已完成但尚未暴露 UserClient 选择器，Swift 应用无法直接调用登录/命令功能 +1. **参考实现稀缺**：仍需持续参考 Linux `firewire-sbp2` 与 Apple `IOFireWireSBP2` 的行为差异 +2. **扫描仪兼容性**：目标扫描仪可能使用厂商特定命令集，不能简单类比存储设备 +3. **OHCI 描述符限制**：Fetch Agent 写操作与命令提交流程仍需更多硬件侧验证 +4. **DMA 一致性**：大数据传输时页表映射与 OHCI 硬件同步仍是高风险点 +5. **DriverKit API 差异**：当前完整 DriverKit 构建仍被 `IODispatchQueue::DispatchAsyncAfter` 用法阻塞，需要先修正 ORB 定时实现 +6. **硬件验证缺口**：当前已打通软件调试闭环，但真机 `login + inquiry` smoke 还未形成稳定证据 +7. **生命周期收口不足**：bus reset / reconnect 的类内能力已存在，但系统级接线与恢复策略仍待验证 From e0d54311bd312036216b2369ee2936154be80c39 Mon Sep 17 00:00:00 2001 From: gly11 Date: Wed, 22 Apr 2026 16:44:23 +0800 Subject: [PATCH 24/45] feat: Implement SBP-2 command handling and metadata structures - Added SubmitSBP2Command and GetSBP2CommandResult methods to SBP2Handler for command submission and result retrieval. - Introduced SBP2CommandWireFormats.hpp to define wire formats for SBP-2 command requests and results. - Extended DeviceDiscoveryWireFormats to include management agent offset, LUN, unit characteristics, and fast start fields. - Created SBP2SessionRegistryTests to validate command submission and response handling. - Updated documentation to reflect the current state and goals of the SBP-2 scanner integration. ---

构建仍被 `IODispatchQueue::DispatchAsyncAfter` 用法阻塞，需要先修正 ORB 定时实现 -6. **硬件验证缺口**：当前已打通软件调试闭环，但真机 `login + inquiry` smoke 还未形成稳定证据 -7. **生命周期收口不足**：bus reset / reconnect 的类内能力已存在，但系统级接线与恢复策略仍待验证 +1. **扫描仪未必遵循块设备语义** + - 当前实现已避免把 scanner bring-up 绑定到 storage 语义，但后续仍需根据真机证据决定命令集合 + +2. **raw CDB 是 bring-up 必需能力** + - 对扫描仪而言，这不是调试锦上添花，而是识别厂商协议的基础能力 + +3. **真机验证仍是主要缺口** + - 当前软件路径已打通，但是否能稳定工作仍取决于硬件侧

AR DMA test helpers now correctly use little-endian byte order matching OHCI hardware. Bus reset discovery always applies a 100ms baseline delay matching Apple ScanBus behavior. Cycle master is disabled by default; explicit PHY bus reset removed in favor of linkEnable auto reset.

- 输出应在主操作成功时保留成功结果；logout cleanup 失败只记录为 warning - -2. **继续收敛 async read / management agent CSR direct-read 诊断** - - 已确认 discovery 已给出 `Management_Agent_Offset=0x00c000 -> csr_addr=0xF0030000` - - 已从 dext 日志确认：`0xF0000400` block read 的真实响应是 `rCode=0x07 (AddressError)` - - 已从 dext 日志确认：`0xF0030000` quadlet read 的真实响应是 `rCode=0x06 (TypeError)` - - 下一步优先对照 Apple / Linux 行为判断：这些 rCode 是目标设备的合法拒绝，还是 ASFW block request 线上的格式/时序问题 - -3. **补 FireWire 硬盘对照，区分“全局 block-read 坏”还是“Nikon 特有”** - - 在同一 Thunderbolt adapter 上对已知 FireWire 硬盘重复： - - `mcs tx read --node --address 0xF0000400` - - `mcs tx block-read --node --address 0xF0000400 --length 8` - - 若硬盘也失败，优先排查 ASFWDriver async block transaction / AT descriptor / response parsing - - 若仅 Nikon 失败，优先继续 bus timing / 设备初始化路径 - -4. **继续补 owner 生命周期与清理回归** - - `mcs-cli sbp2 inquiry --node 0` 之前出现的 `allocateAddressRange failed: 0xe00002db`，已定位并修复为 user client `Stop/free` 未释放 owner 绑定资源 - - 仍需补更系统的断连 / reset / 重复 create-release 回归，确认不会残留 DMA、地址空间或旧结果 - -5. **在 login 真正跑通后重新执行完整 SBP-2 smoke** - - 固定顺序： - - discover - - create session - - start login - - inquiry - - test unit ready - - request sense - - raw cdb - - release - - 保存 generation、loginID、transport status、SBP-2 status、sense、raw CDB payload - -6. **bus reset / reconnect 验证** - - reset 期间确认新命令被拒绝 - - in-flight 命令确认进入失败态 - - reconnect 后确认 session 可继续使用 - -7. **补强回归** - - 按需增加 session 清理、reset 收敛、raw CDB 错误路径测试 - ---- - -## 风险与注意事项 - -1. **扫描仪未必遵循块设备语义** - - 当前实现已避免把 scanner bring-up 绑定到 storage 语义，但后续仍需根据真机证据决定命令集合 - -2. **raw CDB 是 bring-up 必需能力** - - 对扫描仪而言，这不是调试锦上添花，而是识别厂商协议的基础能力 - -3. **真机验证仍是主要缺口** - - 当前软件路径已打通，但是否能稳定工作仍取决于硬件侧 login、命令完成与 reset 行为 - -4. **DriverKit 构建虽已恢复，运行时行为仍需实机确认** - - 构建通过不等于扫描仪协议行为已稳定 diff --git a/install-debug-asfw.sh b/install-debug-asfw.sh deleted file mode 100755 index 00bb284b..00000000 --- a/install-debug-asfw.sh +++ /dev/null @@ -1,338 +0,0 @@ -#!/usr/bin/env bash -set -euo pipefail -
