LPI 始终是基于消息的中断,它们的配置保存在表中而不是寄存器。比如 PCIe 的 MSI/MSI-x 中断。 GIC v3 组成 GICv3 控制器由以下三部分组成: Distributor:SPI 中断的管理,将中断发送给 Redistributor 打开或关闭每个中断。Distributor对中断的控制分成两个级别。一个是全局中断的控制(GIC_DIST_CTRL)。一旦关闭了全...
Refer to theT23x BCT Deployment Guidefor more information. To configure PCIE, CAN, and SPI and generate the correct .dtsi files from theJetson AGX Orin pinmux spreadsheet, complete the steps inPinmux Changes. For debugging purposes, dynamically change the pinmux. In the...

也就是最终通过msi_set_affinity来实现,在该函数中首先通过 __ioapic_set_affinity在绑定属性要求的cpu中选择空闲vector,然后通过__write_msi_msg把配置写入PCIE配置区。需要说明的是:该irq最终可以运行的cpu数量并不完全由用户指定,还与apic的模式相关,对于apic_physflat,实际上只为该irq分配了一个cpu核心,该irq...
RAS涉及的硬件包括且不限于:CPU、Memory、IO、PCIe、硬盘和其他外设 •CPU – detect errors at instruction execution and at L1/L2/L3 caches; •Memory – add error correction logic (ECC) to detect and correct errors; •I/O – add CRC checksums for tranfered data; ...
