* | metag: System Calls | James Hogan | 2013-03-02 | 1 | -0/+180 |
Add metag system call and gateway page interfaces. The metag architecture port uses the generic system call numbers from asm-generic/unistd.h, as well as a user gateway page mapped at 0x6ffff000 which contains fast atomic primitives (depending on SMP) and a fast method of accessing TLS data. System calls use the SWITCH instruction with the immediate 0x440001 to signal a system call. Signed-off-by: James Hogan <james.hogan@imgtec.com> |
