From 497e4a1b2f6f9181518e9887991c0464bd8f6bcf Mon Sep 17 00:00:00 2001 From: Richard Qin Date: Wed, 10 Dec 2025 01:19:32 +0800 Subject: feat: Add initial Supervisor Mode Trap Handler Implement the initial mechanism for handling traps and exceptions in Supervisor Mode. Set up the stvec Control and Status Register (CSR) to direct all S-Mode Traps (Interrupts and Exceptions) to a unified assembly entry point. Implemented assembly code for saving and restoring the Trap Context (register state). Provides the foundational framework necessary for future Timer Interrupts and System Calls. --- include/drivers/uart.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/drivers') diff --git a/include/drivers/uart.h b/include/drivers/uart.h index 8bf4560..4d00d94 100644 --- a/include/drivers/uart.h +++ b/include/drivers/uart.h @@ -1,7 +1,9 @@ #pragma once +typedef unsigned long long uint64_t; namespace Drivers { void uart_init(); void uart_putc(char c); void uart_puts(const char* s); + void print_hex(uint64_t val); } \ No newline at end of file -- cgit v1.2.3
