PC711Probe 1.7.0

PC711Probe 1.7.0

Complete macOS 11–15 PC711 compatibility update. / 完整覆盖 macOS 11–15 的 PC711 兼容性更新。

Changes / 变化

• Keeps one automatic PC711Probe.kext, restricted to SK hynix 1C5C:174A with NVMe class 01:08:02. / 保持单个自动运行的 PC711Probe.kext，仅匹配 SK hynix 1C5C:174A 与 NVMe class 01:08:02。
• Switches Big Sur's existing PC711 MSI allocation to MSI-X before Apple IONVMeFamily attaches. / 在 Apple IONVMeFamily 接管前，把 Big Sur 为 PC711 分配的 MSI 切换为 MSI-X。
• Requests MSI-X during early PCI matching on macOS 12–15, covering Recovery and second-stage Installer polled commands. / 在 macOS 12–15 的 PCI 匹配早期请求 MSI-X，覆盖 Recovery 与安装第二阶段的轮询命令。
• Retains the later macOS 14–15 interrupt-source route as a fallback. / 保留 macOS 14–15 的中断源兼容路由作为后备。
• Does not load on macOS 26, where the tested PC711 works natively. / macOS 26 不加载本插件，实测 PC711 已原生免驱。

Matching boundary / 匹配边界

The patch runs before NVMe Identify and therefore matches PCI 1C5C:174A plus NVMe class 01:08:02, not the later model string. This PCI identity is also reported by SK hynix Gold P31 and BC711 devices. Only SKHynix_HFS512GDE9X084N, firmware 41010C22, has been hardware-validated; every other 1C5C:174A device remains untested. / 补丁在 NVMe Identify 之前运行，因此匹配 PCI 1C5C:174A 与 NVMe class 01:08:02，而不是稍后才能读取的型号字符串。SK hynix Gold P31 和 BC711 也有使用该 PCI 身份的记录。目前只实机验证了固件 41010C22 的 SKHynix_HFS512GDE9X084N；其他 1C5C:174A 设备均未验证。
