|
Method 1b: Declare the I2C devices via devicetree
|
||||||
|
-------------------------------------------------
|
||||||
|
|
||||||
|
This method has the same implications as method 1a. The declaration of I2C
|
||||||
|
devices is here done via devicetree as subnodes of the master controller.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
i2c1: i2c@400a0000 {
|
||||||
|
/* ... master properties skipped ... */
|
||||||
|
clock-frequency = <100000>;
|
||||||
|
|
||||||
|
flash@50 {
|
||||||
|
compatible = "atmel,24c256";
|
||||||
|
reg = <0x50>;
|
||||||
|
};
|
||||||
|
|
||||||
|
pca9532: gpio@60 {
|
||||||
|
compatible = "nxp,pca9532";
|
||||||
|
gpio-controller;
|
||||||
|
#gpio-cells = <2>;
|
||||||
|
reg = <0x60>;
|
||||||
|
};
|
||||||
|
};
|
||||||
|
|
||||||
|
Here, two devices are attached to the bus using a speed of 100kHz. For
|
||||||
|
additional properties which might be needed to set up the device, please refer
|
||||||
|
to its devicetree documentation in Documentation/devicetree/bindings/.
|
||||||
|
|
||||||
|
|
||||||
|
Method 1c: Declare the I2C devices via ACPI
|
||||||
|
-------------------------------------------
|
||||||
|
|
||||||
|
ACPI can also describe I2C devices. There is special documentation for this
|
||||||
|
which is currently located at Documentation/acpi/enumeration.txt.

Linux 在 AArch64 中带标记的虚拟地址
|
||||||
|
=================================

||||||

|
||||||
|
本文档简述了在 AArch64 地址转换系统中提供的带标记的虚拟地址及其在
|
||||||
|
AArch64 Linux 中的潜在用途。
|
||||||
|
|
||||||
|
内核提供的地址转换表配置使通过 TTBR0 完成的虚拟地址转换（即用户空间
|
||||||
|
映射），其虚拟地址的最高 8 位（63:56）会被转换硬件所忽略。这种机制
|
||||||
|
让这些位可供应用程序自由使用，其注意事项如下：
|
||||||
|
|
||||||
|
(1) 内核要求所有传递到 EL1 的用户空间地址带有 0x00 标记。
|
||||||
|
这意味着任何携带用户空间虚拟地址的系统调用（syscall）
|
||||||
|
参数 *必须* 在陷入内核前使它们的最高字节被清零。
|
||||||
|
|
||||||
|
(2) 非零标记在传递信号时不被保存。这意味着在应用程序中利用了
|
||||||
|
标记的信号处理函数无法依赖 siginfo_t 的用户空间虚拟
|
||||||
|
地址所携带的包含其内部域信息的标记。此规则的一个例外是
|
||||||
|
当信号是在调试观察点的异常处理程序中产生的，此时标记的
|
||||||
|
信息将被保存。
|
||||||
|
|
||||||
|
(3) 当使用带标记的指针时需特别留心，因为仅对两个虚拟地址
|
||||||
|
的高字节，C 编译器很可能无法判断它们是不同的。
|
||||||
|
|
||||||
|
此构架会阻止对带标记的 PC 指针的利用，因此在异常返回时，其高字节
|
||||||
|
将被设置成一个为 “55” 的扩展符。
