From 2939a7089ad89e38b24f96143dbd3c4292ac0287 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 3 Feb 2006 00:16:44 -0500 Subject: byte_swap.hh was removed from arch/alpha/, and replaced by sim/byteswap.hh. The new file uses LittleEndianGuest and BigEndianGuest namespaces to allow selecting the appropriate functions. arch/alpha/alpha_linux_process.cc: arch/alpha/alpha_tru64_process.cc: Added the endianness namespace. This may change. cpu/exec_context.hh: Changed the include path for byteswap, and forced LittleEndianness for lack of a better solution. cpu/o3/alpha_cpu.hh: Forced LittleEndianness, for lack of a better solution. cpu/o3/alpha_cpu_impl.hh: Cleared away some commented out code. cpu/o3/fetch_impl.hh: Changed the include patch for byteswap, and forced LittleEndianness for lack of a better solution. cpu/simple/cpu.cc: Added an include for byteswap.hh, and fixed the SimpleCPU to LittleEndian. This cpu only does alpha, so that's fine. dev/disk_image.cc: Changed the include path of byteswap.hh kern/freebsd/freebsd_system.cc: kern/linux/linux_system.cc: Added an include for byteswap.hh, and forced LittleEndianness for lack of a better solution. sim/system.cc: Forced LittleEndianness for lack of a better solution. --HG-- extra : convert_revision : b95d3e1265a825e04bd77622a3ac09fbac6bd206 --- kern/linux/linux_system.cc | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'kern/linux') diff --git a/kern/linux/linux_system.cc b/kern/linux/linux_system.cc index 1144b9bdd..26a4c0d3e 100644 --- a/kern/linux/linux_system.cc +++ b/kern/linux/linux_system.cc @@ -44,6 +44,7 @@ #include "mem/functional/memory_control.hh" #include "mem/functional/physical.hh" #include "sim/builder.hh" +#include "sim/byteswap.hh" #include "dev/platform.hh" #include "targetarch/arguments.hh" #include "targetarch/vtophys.hh" @@ -100,7 +101,7 @@ LinuxSystem::LinuxSystem(Params *p) char *dp264_mv = (char *)physmem->dma_addr(paddr, sizeof(uint64_t)); if (dp264_mv) { - *(uint32_t*)(dp264_mv+0x18) = htog((uint32_t)127); + *(uint32_t*)(dp264_mv+0x18) = LittleEndianGuest::htog((uint32_t)127); } else panic("could not translate dp264_mv addr\n"); -- cgit v1.2.3 From 2c5e03550adcd1348cc1d6f3c00af77cbf99c5ce Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Sun, 12 Feb 2006 12:40:58 -0500 Subject: Removed isa_traits.hh from targetarch, moved vptr.hh from arch/alpha to sim, fixed an include to have the new location, and removed an ambiguating function declaration in byteswap.hh.

Also several files need to include system.hh or symtab.hh. This is because exec_context.hh has less #includes than before, requiring some of the files that include it to include some other files as well. arch/alpha/faults.cc: Avoid accessing XC directly. arch/alpha/stacktrace.cc: StackTrace needs to include system.hh. cpu/cpu_exec_context.cc: Update for change to CPUExecContext. cpu/cpu_exec_context.hh: Make quiesce events use CPUExecContext instead of ExecContext. Include functions to allow the quiesce event and last activate/suspend be accessed. cpu/exec_context.hh: Include functions for quiesceEvent. cpu/intr_control.cc: Needs to include cpu/exec_context.hh. cpu/profile.cc: Needs to include symtab.hh for the symbol table. cpu/profile.hh: Needs forward declare of ExecContext. cpu/simple/cpu.cc: Rename xc to cpuXC. dev/tsunami_cchip.cc: Needs to include exec_context.hh. kern/kernel_stats.cc: Needs to include system.hh. kern/linux/events.cc: Needs to include system.hh. Also avoid accessing objects directly from the XC. kern/tru64/dump_mbuf.cc: Include symtab.hh for the SymbolTable and system.hh. kern/tru64/tru64_events.cc: Include system.hh sim/pseudo_inst.cc: Avoid accessing objects directly within the XC. --HG-- extra : convert_revision : 78fe30d98cd20f7403fa216f772071458b675c84 --- kern/linux/events.cc | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'kern/linux') diff --git a/kern/linux/events.cc b/kern/linux/events.cc index a781165ac..9f50eef04 100644 --- a/kern/linux/events.cc +++ b/kern/linux/events.cc @@ -32,6 +32,7 @@ #include "kern/linux/events.hh" #include "kern/linux/printk.hh" #include "kern/system_events.hh" +#include "sim/system.hh" namespace Linux { @@ -41,7 +42,7 @@ DebugPrintkEvent::process(ExecContext *xc) { if (DTRACE(DebugPrintf)) { if (!raw) { - StringWrap name(xc->system->name() + ".dprintk"); + StringWrap name(xc->getSystemPtr()->name() + ".dprintk"); DPRINTFN(""); } -- cgit v1.2.3
