From 2fd427c7926495b3e1ad3c7aaaa489f8cde95573 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 5 Jun 2008 14:30:07 +0000 Subject: 2008-06-05 Joel Sherrill * rtems/score/cpu.h: Add CPU_SIMPLE_VECTORED_INTERRUPTS porting parameter to indicate that the port uses the Simple Vectored Interrupt model or the Programmable Interrupt Controller Model. The PIC model is implemented primarily in the BSP and it is responsible for all memory allocation. --- cpukit/score/cpu/unix/ChangeLog | 8 ++++++++ cpukit/score/cpu/unix/rtems/score/cpu.h | 9 +++++++++ 2 files changed, 17 insertions(+) (limited to 'cpukit/score/cpu/unix') diff --git a/cpukit/score/cpu/unix/ChangeLog b/cpukit/score/cpu/unix/ChangeLog index c582284e9f..571f638759 100644 --- a/cpukit/score/cpu/unix/ChangeLog +++ b/cpukit/score/cpu/unix/ChangeLog @@ -1,3 +1,11 @@ +2008-06-05 Joel Sherrill + + * rtems/score/cpu.h: Add CPU_SIMPLE_VECTORED_INTERRUPTS porting + parameter to indicate that the port uses the Simple Vectored + Interrupt model or the Programmable Interrupt Controller Model.
