From d2aebee488b71e6f28b8728e7473b63f412ca897 Mon Sep 17 00:00:00 2001 From: Alex AUVOLAT Date: Thu, 11 Jul 2013 22:38:20 +0200 Subject: Added direct acces to video memory from userland. Next : same for keyboard ; move VT handling to userland. Consequence : a foreground app has total control over I/O. Next : implement sockets & a userland console multiplexer. --- src/kernel/task/syscall.cpp | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/kernel/task') diff --git a/src/kernel/task/syscall.cpp b/src/kernel/task/syscall.cpp index a3074b8..2e1350e 100644 --- a/src/kernel/task/syscall.cpp +++ b/src/kernel/task/syscall.cpp @@ -78,6 +78,10 @@ static void link_sc(registers *r) { r->eax = link((char*)r->ebx, (char*)r->ecx, r->edx); } +static void devcontrol_sc(registers *r) { + r->eax = dev_control(r->ebx, (char*)r->ecx); +} + int_callback syscalls[NUMBER_OF_SYSCALLS] = { // This must correspond to common/include/tce/syscalls.h 0, // 0 @@ -109,6 +113,7 @@ int_callback syscalls[NUMBER_OF_SYSCALLS] = { // This must correspond to common read_sc, write_sc, link_sc, + devcontrol_sc, 0 }; -- cgit v1.2.3
