From 1166d4f0bfe67a9dc178be3454b4f0eac38663ad Mon Sep 17 00:00:00 2001 From: Ali Saidi Date: Thu, 23 Feb 2006 14:50:16 -0500 Subject: Get rid of the xc from the alphaAccess/alphaConsole backdoor device. Now allocate an array of stacks indexed by cpu number which specify cpu stacks and are initialized by cpu 0. Othe cpus spin waiting for their stacks before continuing. This change *REQUIRES* a the new console code to operate correctly. arch/alpha/ev5.cc: Add cpuId to initCPU/initIPR functions cpu/o3/cpu.cc: cpu/simple/cpu.cc: cpu/simple/cpu.hh: Move the cpu initilization into an init() function since it now needs the CPU id which isn't known at construction dev/alpha_access.h: dev/alpha_console.cc: dev/alpha_console.hh: instead of the bootstrap variables, add space for 64 cpu stacks in the alpha access structure. sim/system.cc: start all cpus immediately rather than just the first one --HG-- extra : convert_revision : 28c218af49d885a0f203ada419f16f25d5a3f37b --- dev/alpha_access.h | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'dev/alpha_access.h') diff --git a/dev/alpha_access.h b/dev/alpha_access.h index a20a05535..5a1df6f39 100644 --- a/dev/alpha_access.h +++ b/dev/alpha_access.h @@ -33,7 +33,7 @@ * System Console Memory Mapped Register Definition */ -#define ALPHA_ACCESS_VERSION (1303) +#define ALPHA_ACCESS_VERSION (1305) #ifdef CONSOLE typedef unsigned uint32_t; @@ -67,9 +67,7 @@ struct AlphaAccess uint64_t inputChar; // 68: Placeholder for input // MP boot - uint64_t bootStrapImpure; // 70: - uint32_t bootStrapCPU; // 78: - uint32_t align2; // 7C: Dummy placeholder for alignment + uint64_t cpuStack[64]; // 70: }; #endif // __ALPHA_ACCESS_H__ -- cgit v1.2.3
