Toby Jaffey	147a9f2198	Split includes. ... All code needs uvm32_sys.h, but uvm32_common_custom.h is optional (and has defs needed for demos)	2025-12-12 15:56:47 +00:00
Toby Jaffey	ed57b62f79	Add render and getkey syscalls, for host-sdl use.	2025-12-12 14:25:01 +00:00
Toby Jaffey	76fba39a21	Rework syscall ABI. ... Syscalls now accept two parameters, allowing for things like "int count = read(buf, len)" Rather than providing safe signatures for syscalls, the user is now given helper functions to safely parse incoming values, c-strings and slices.	2025-12-09 21:51:35 +00:00
Toby Jaffey	6735b159ac	Make syscall names closer to libc	2025-12-08 16:28:00 +00:00
Toby Jaffey	9d6e6790e1	Cleanup syscall numbers	2025-12-08 12:53:33 +00:00
Toby Jaffey	61fe0e8647	Rename ioreq to syscall	2025-12-08 12:26:47 +00:00
Toby Jaffey	751f068486	Rework host/target interface to use ecall and proper syscalls instead of CSRs	2025-12-08 02:44:38 +00:00
Toby Jaffey	9e6f6c5a67	Added IOREQ_MILLIS and IOREQ_GETC to get current time and poll keyboard. ... IOREQ_GETC implemented inefficiently, but is fine for demo purposes.	2025-12-07 20:29:10 +00:00
Toby Jaffey	c9d30b6d28	uvm32 initial version	2025-12-06 16:44:23 +00:00
