在我们的代码中,对于此外设的访问,采用writel接口,也就是四字节读写。 通过异常日志可以看到,异常时的地址为 xxxxxx2,ffffffc011b18302 此地址非4的倍数。 那么再走读代码,查看到对寄存器偏移访问时,使用了如下数据结构。 AI检测代码解析 struct pci_usb_reg { ...
Write code that uses these instructions in an embedded assembler function. Use an appropriate member of the __sync_* family of GNU built-in functions, for example __sync_lock_test_and_set(). [SDCOMP-28842] The ‑‑fpu option has been extended to support the FPv5 architecture: ‑...
The access rules are enforced based on specific properties of a transfer, such as an address range for the transfer and access attributes (such as read/write, user/privilege, and secure/non-secure). Datasheet 12 of 168 ...
