amd_pmu_v2_handle_irq should be used to handle PMU overflow in AMD processor. When I use perf top -ag in the system, it is heavily called. But when I use the perf stat -a command, there are fewer calls to this function, why is that? And why is there a very small number ...
Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq(). Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Krzysztof Kozlowski <krzysztof.kozlowsk...
// 使能/禁能IRQ、FIQ中断 __swi(0x00) void SwiHandle1(int Handle);这句话怎么分析 __swi是ADS编译器的关键字,用它做前缀可以声明一个软中断调用,格式为: __swi(功能号) 返回值 名称 (参数列表) 功能号:即软中断指令中的24位立即数,软中断号 名 称:即调用软中断

The chip model I use is EFR32BG22C224. Now I write UART programs based on soc_empty routines. Instead of using the official UART driver, I initialize, enable and open the interrupt by operating registers.After testing, the UART was able to send data normally, but it was difficult to tr...
