# 授人以渔
要参照对比学习！
# 提取 DSDT
1. 在Mac 下，用MaciASL就可以直接获取DSDT信息（New from ACPI）。
2. 启动到 Clover 界面，按键盘 F4（部分笔记本可能是`F4+Fn`）会自动提取 DSDT 文件到 U 盘`EFI/ClOVER/ACPI/origin` 文件夹下
# FN 小太阳
用 MaciASL 打开 `DSDT.aml`，然后搜索 0x86 和 0x87 (不要问为什么是这两个值，不多谈，经验所得，知道这两个值是跟亮度调节有关的！
本机 是在 `_Q11` 和 `_Q12` 两个方法中！
# 原生电源管理
1. MaciASL.app 打开 DSDT.aml
2. 然后搜索你 CPU 的名字。一般情况下，CPU 的名字可能是:`PR.CPU0`,`PR.P000`,`PR.PR00`,`SB.CPU0`,`SB.P000`,`SB.PR00`, `SCK0.C000`, `SCK0.CPU0`。请依次搜索直到找到自己的CPU名字，比如我的 PC 就是`PR.CPU0`
3. 仓库地址在这里:https://github.com/daliansky/OC-little ，找到“电源 -> 注入X86文件夹”，寻找包含有自己 CPU 名字的 dsl 文件。
4. 另存为，文件名字随便写吧，就叫`PLUG-XCPM.aml`，记住后缀为`.aml`。
5. 将 `PLUG-XCPM.aml`放入 OC 引导文件夹`EFI/OC/ACPI`下，并在 config.plist 中添加加载此`.aml`文件。
6. 重启系统（不行的话，可以尝试清理一次 nvram），我们看到“偏好设置–节能中，原生电源管理已经被加载了。
7. 一般有4项节能出现，而第五项“断电后重启”这项还需要加载 PPMC 以及 LPCB 下的 PMCR 才能出现。虽然说这项功能没啥鸟用，使用通用的`SSDT-PM.aml`载入即可。
提醒一下，并非所有的机型都可以开启“节能四项”或“节能五项”，如 Mac mini 仅提供三项，具体情况可以参考苹果官方帮助文档:https://support.apple.com/zh-cn/HT202824 。
> [手把手教你 黑苹果加载原生电源管理，开启节能五项！](https://macx.top/8842.html)
## 加载 AppleLPC 驱动原生电源管理
结合以下两个 方法，使用 Hackintool 工具 “> PCIe -> Device Name” 下 查找 LPC 关键字，来修改 VirtualSMC.kext 中的`info.plist`文件，注意字母小写！

# 电量显示（笔记本）
先搜索电池相关设备所在位置：是 `EC` 还是 `H_EC` 还是 `EC0`；本机 `EC` 位置：
```
Scope (_SB.PCI0.LPCB)
{
Device (EC)
{
Name (_HID, EisaId ("PNP0C09")) // _HID: Hardware ID
```
可以看出 EC 的 ACPI 路径为 `_SB.PCI0.LPCB.EC`，我们需要寻找位于该范围下 `OperationRegion` 和 `Field`
## 筛选 过 8位
```
OperationRegion (RAM, SystemMemory, 0xFF700100, 0x0100)
Field (RAM, ByteAcc, Lock, Preserve)
{
...
}
...
OperationRegion (EC81, EmbeddedControl, Zero, 0xFF)
Field (EC81, ByteAcc, Lock, Preserve)
{
...
}
```
清理找出 存在被调用的情况）整理出：
16 位： OEM3
拆分：
OEM3：OE0M OE1M
32 位：
BDC0 BFC0 BDV0 BST0 BPR0 BRC0 BPV0 BCW0 BCL0
拆分：
BD0C BF0C BD0V BS0T BP0R BR0C ...
需要修改的 Method：
```
_SB.PCI0.LPCB.EC._Q35
_SB.PCI0.LPCB.EC._Q37
_SB.WMI.GCMD
_SB.BAT0.UPBI
_SB.BAT0.UPBS
```
## 需要 16 位和32 位拆分函数
添加 16 位拆分读取 `B1B2` 函数
添加 32 位拆分读取 `B1B4` 函数
写入注意！：
```
Store (RECB (0x64, 0x0100), FB4)
WECB (0x64, 0x0100, FB4)
```
## 计算 offset
要点：8 bit 进 1
```
OperationRegion (XRAM, SystemMemory, 0xFF700100, 0x0100) // 保持原来的起始偏移量，其他位置可能要加上原起始偏移量
Field (XRAM, ByteAcc, Lock, Preserve)
{
Offset (0x16), // 根据原 DSDT.dsl 位置的 BDC0 前一个值的位置（保持 8进1 ，十六进制）
BD0C, 8,
BD1C, 8,
BD2C, 8,
BD3C, 8,
BF0C, 8,
```
## EC 域外的引用修改
代码段: `If (LNot (^^LPCB.EC0.BATP (Zero)))`
`^^LPCB.EC0.BATP` 这个方法写法中存在 `^^` 这两个字符，意思上级的上级域里面的，类似于相对路径，`LPCB.EC.BATP` 方法，完整路径就是 `\\\_SB.PCI0.LPCB.EC0.BATP`, 因为这个方法不在我们的 SSDT 里面，故此我们需要外部引入他。在 `External` 的部分加入 `External (\\\_SB.PCI0.LPCB.EC0.BATP, MethodObj)`
但是上面的 `^^LPCB.EC0.BATP` 这样的调用方法猜测应该是同一 SSDT 或是在 DSDT 中存在才能这样写，如果是外部引入后，我们需要将其改成绝对路径.
将 `^^LPCB.EC0.BATP` 替换成 `\\\_SB.PCI0.LPCB.EC0.BATP`.
```
* 140, 6084, Object does not exist (NBIX)
```
或者：
```
B1B2 (^^PCI0.LPCB.EC.OE0M, ^^PCI0.LPCB.EC.OE1M)
改为
If ((B1B2 (^^PCI0.LPCB.EC0.ADC0, ^^PCI0.LPCB.EC0.ADC1) < 0x0C80))
```
## 注意
改名函数参数个数！
注意返回值！不是所有函数都定义了返回值！
```
...
Else
{
IVBI () // 没有返回
}
}
Else
{
Return (\_SB.PCI0.LPCB.EC0.XTST(Arg0, Arg1)) // 这里其实不需要 Return ，并且加了参数
}
```
## 改名！
最后好需要 配合在 `OC/ACPI/patch` 中改名！
## 结果：
```swift
// battery
// In config ACPI, _Q35 renamed XQ35
// Find: 5F513335 00
// Replace: 58513335 00
//
// In config ACPI, _Q37 renamed XQ37
// Find: 5F513337 00

将驱动 [ACPIBatteryManager.kext](https://github.com/fishrong/ASUS-FL5500L-EFI/tree/master/EFI/CLOVER/kexts/Other/ACPIBatteryManager.kext/Contents) 放到 clover 的 kexts 目录下，再向 **DSDT** 中打相应补丁，在 [Rehabman 电池补丁](https://github.com/RehabMan/Laptop-DSDT-Patch/tree/master/battery)找自己电脑相应型号的补丁。将生成的 **DSDT.aml** 放到 **EFI/CLOVER/patched/。**
如果重启没有效果，可尝试拔下电源适配器（笔记本）再重启。

# acpi 打补丁 – OpenCore
为了让黑果更加接近白果，在很多方面我们都需要打补丁，如 USB，原生电源管理，开关机，显卡等等很多方面完善都需要用到打补丁。
我们举个例子说明如何打补丁 。 比如我们想把xhc 下的 `_PRW` 进行改名为 `XPRW`。
~~~
Comment String XHC:_PRW to XPRW
Count Number //需要重点解释
Enabled Boolean True //表示应用此补丁，不应用选False
Find Data 5F505257 //hex转text的含义即是：_PRW
Limit Number 0 //这个按默认即可 不去管他
Mask Data <> //这个按默认即可 不去管他
OemTableId Data <> //这个按默认即可 不去管他
Replace Data 58505257 //hex转text的含义即是：XPRW
ReplaceMask Data <> //这个按默认即可 不去管他
Skip Number //需要重点解释
TableLength Number 0 //这个按默认即可 不去管他
TableSignature Data 44534454 //hex转text的含义即是：DSDT，这里按默认即可，代表对dsdt进行修改
~~~
oc 的 tgtbridge 是通过一个数过去来定位具体哪一个位置的。
比如 xhc 的 prw 是整张 dsdt 里面的第 55 个，那 skip 填 54，意味着跳过前 54 个，从第 55 个开始执行。那执行多少次呢？执行一次 count 就填 1；比如你要同时改第 55 个和 56 个，那 count 就填 2。
```
grep -nr "GPRW" *.dsl // 查找具体位置
grep -cnr "GPRW" *.dsl // 查找具体个数
```
然后以 -v 重启，看看能不能正常开机。如果可以正常开机，登录以后打开终端执行以下命令，查看日志中是否包括 ACPI Error：
```
$ log show --last boot | grep -Ei "ACPI"
```
