gic

Arm的GIC库该库提供了Arm的GIC的API。初始化安全世界的主CPU use gic :: v2 :: GICv2; let gicv2 = GICv2 :: new (GICD_BASE, GICC_BASE); let props = []; // Primary CPU initialization // Enable the secure GIC distributor interface // Enable SPIs, PPIs & SGIs gicv2. distif_init ( & props); // Per CPU initialization // Enable the Group 0 SGIs and PPIs gicv2. pcpu_distif_init ( & props); // Enable secure interrupts and use

gic stream协议是一种基于AXI-stream协议的通信协议，用于在gic的IRI组件（interrupt routing infrastructure）和cpu interface之间传输信息。IRI组件包括distributor、redistributor和ITS。在gicv3中，IRI组件与cpu interface之间使用AXI-stream协议传输信息，通过包的组合实现gic的中断操作与中断管理。此外，gicv3还引入了一种新的中断类型，称为消息中断。123 #### 引用[.reference_title] - *1* [ARM_GIC3/4](https://blog.csdn.net/wangwangmoon_light/article/details/122006746)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 33.333333333333336%"] - *2* [undefined](undefined)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 33.333333333333336%"] - *3* [【转】ARM GIC中断系列（四）：gicv3架构-gic stream协议](https://blog.csdn.net/weixin_45264425/article/details/128364816)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_2"}}] [.reference_item style="max-width: 33.333333333333336%"] [ .reference_list ]
