MeowOS
ade0a57353
- meow_audiod：启动门控(/tmp/meow_boot_mode 非 meow exit 0)、IO/播放/路由三线程、
ring ~200ms、ALSA UAPI 独占直开、切率 mute-重配-恢复、抢占(后开赢+PREEMPTED)、
socket EOF 回收、xrun PREPARE 恢复；meow_route 轮询逻辑并入路由线程
- meow_audio CLI：status/tone/route/vol；services.d/audiod.conf(trigger=manual,on-fail)
- SDK meow_ui_audio.c 编进 meow_ui.a：懒连接/读线程分发 PREEMPTED 回调/EPIPE 标死/
无 audiod 返回 MEOW_ERR_NOENT 不隐式直开(MEOW_AUDIO_DIRECT=1 仅调试)
- launcher：确认 MeowOS 模式后 meow_svcd start audiod(double-fork best-effort 不阻塞)
- meow_route 退役：S89 预置换 audiod.conf + 清理旧 meow_route.conf(防拉起已删二进制
重启循环)；fw_content.conf 删 meow_route、加 meow_audiod+meow_audio(md5 打包时填)
- 真机定位并修复 ALSA UAPI 两大坑(即 ncm 播放无声根因)：
① hw_params 须全放行初始化(mask 全 1/interval [0,UINT_MAX])，memset 0 interval
等价只能取 0 → refine 必空 → HW_PARAMS 恒 EINVAL
② access/format mask 先清零再单点(pmask 只 OR)，全 1 被 choose 成 MMAP_INTERLEAVED
→ write() 恒 EINVAL
- 附带修复：dev_write fd<0 防日志风暴丢 PCM 限频日志；SDK state 解析 app_id 截空白；
meow_ui.h 文档负错误码表述修正
- 验证：宿主 FILE sink 全 IPC 链+抢占+tone WAV 20/20，SDK 客户端 13/13；
qemu-mipsel 同过；真机 tone 44.1k/96k 切率 written=played、underrun=0、日志完整
- meow_ui.a 53a3edd2 → ncm 重链 d2031829(已热更到卡)；launcher a2f932a1

#
|
||
# 位置：S70meow_sysui 之后、S90meow_bootmenu 之前（S70 < S84 < S89 < S90）。
|
||
# * rcS 顺序执行 /etc/init.d/S??*，而 S90meow_bootmenu 里 `exec /usr/bin/meow_bootmenu
|
||
# --fork` 会阻塞 rcS（选单后 exec meow_launcherd 或 fork 播放器监督），故任何 S90
|
||
# 之后的 init.d（如 S91/S92）**都不会执行**——svcd 必须排在 S90 之前。
|
||
# * 本脚本只装「稳定框架/KB级设置」：主机名 + 板载服务配置
|
||
# （/usr/data/meow/services.d/，Data 区，首启预置 mdnsd.conf + meow_svc_perf.conf +
|
||
# meow_svc_power.conf —— 后者为框架专项服务，trigger=boot 恒存在即启动）。
|
||
# * **svcd 拉起权**：若 meow_sysui（系统进程总监）已运行 → svcd 由 sysui 监管拉起
|
||
# （sysui.d/svcd.conf），本脚本仅在其已运行时 `meow_svcd reload` 让 svcd 补载 mdnsd.conf，
|
||
# 不重复拉起、不重挂（避免与 sysui 双重监护 svcd）。仅当 **sysui 未运行**时才回退到
|
||
# 现网的「重挂循环」自监护（旧固件/无 sysui 场景，向后兼容）。
|
||
#
|
||
# 红线：不 killall、不碰播放器信号、不刷机。svcd 以 -f 前台被 sysui（或重挂循环）拉起；
|

# 服务本身（mdnsd）由 svcd 按 restart=on-fail 托管。
