在我的环境中,中断号可以通过dts(设备树)查到,比如: clint@2000000 { interrupts-extended = <0x02 0x03 0x02 0x07>; reg = <0x00 0x2000000 0x00 0x10000>; compatible = "riscv,clint0"; }; 其中interrupts-extended域中的*0x7*就表示Timer的中断号为7。这里为了简单起见,给出实现mtime时钟中断的伪...
简单说,这个文件用来定义板子上的资源,通过dts编译器生成header提供给metal库用,这样metal就不用手动配置寄存器常量了。 例如pwm硬件的启用,定义如下: pwm1: pwm@10025000 { compatible = "sifive,pwm0"; sifive,comparator-widthbits = <16>; sifive,ncomparators = <4>; interrupt-parent = <&plic>; interr...

在 spike 中,设备树的具体实现位于 riscv/dts.cc 和fdt 文件夹中。接下来借助 spike 的输出简单介绍一下 spike 的设备树。使用安装测试中的 hello 文件进行测试,执行 spike --dumpdts hello 即可看到设备树的输出。 /dts-v1/; / { #address-cells = <2>; #size-cells = <2>; compatible = "ucbbar,...

If using just a PLIC the system must continue to use the original basic xsip/xtip/xeip signals in the xip register to indicate pending interrupts. If using the CLIC then both the original basic and CLIC modes of interrupts must be supported. Embedded systems cannot use a non-compliant inte...
