2014-11-23kvm, x86: Adding support for SE mode executionAlexandru Dutu
This patch adds methods in KvmCPU model to handle KVM exits caused by syscall instructions and page faults. These types of exits will be encountered if KvmCPU is run in SE mode.

2014-04-01arm: fix typos in makefile for ARM m5 util and link staticallyAnthony Gutierrez
1) fixes a typo for clean target libgemOpJni.so -> libgem5OpJni.so 2) addes jni_gem5Op.h to clean since it is added during make 3) links the m5 utility statically since it won't work on some images otherwise
2014-01-24arm: Add support for ARMv8 (AArch64 & AArch32)ARM gem5 Developers
Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64 kernel you are restricted to AArch64 user-mode binaries. This will be addressed in a later patch. Note: Virtualization is only supported in AArch32 mode. This will also be fixed in a later patch.

2013-10-31arm: fix m5ops binary for ARM and add m5fail.Ali Saidi
Changes to make m5ops work under virtualization seemed to break them working with non-virtualized systems and the recently added m5 fail command makes the m5op binary not compile. For now remove the code for virtualization.
2013-09-30x86: Add support for m5ops through a memory mapped interfaceAndreas Sandberg
In order to support m5ops in virtualized environments, we need to use a memory mapped interface. This changeset adds support for that by reserving 0xFFFF0000-0xFFFFFFFF and mapping those to the generic IPR interface for m5ops. The mapping is done in the X86ISA::TLB::finalizePhysical() which means that it just works for all of the CPU models, including virtualized ones.
2013-08-14arm: use -march when compiling m5op_arm.SAnthony Gutierrez
Using arm-linux-gnueabi-gcc 4.7.3-1ubuntu1 on Ubuntu 13.04 to compiled the m5 binary yields the error: m5op_arm.S: Assembler messages: m5op_arm.S:85: Error: selected processor does not support ARM mode `bxj lr' For each of of the SIMPLE_OPs. Apparently, this compiler doesn't like the interworking of these code types for the default arch. Adding -march=armv7-a makes it compile. Another alternative that I found to work is replacing the bxj lr instruction with mov pc, lr, but I don't know how that affects the KVM stuff and if bxj is needed.
2013-05-14arm: Add support for the m5fail pseudo-opAndreas Sandberg
2013-05-14arm: Fix compilation error in m5 utilityAndreas Sandberg
Changeset 5ca6098b9560 accidentally broke the m5 utility. This changeset adds the missing co-processor call used to trigger the pseudo-op in ARM mode and fixes an alignment issue that caused some pseudo-ops to leave thumb mode.
2013-05-07arm: Make libm5 a dependency of the m5 utilityAndreas Sandberg
The m5 utility wasn't relinked properly since libm5.a wasn't a dependency of the utility. This changeset addresses that issue.
2013-04-22kvm: Add support for pseudo-ops on ARMAndreas Sandberg
This changeset adds support for m5 pseudo-ops when running in kvm-mode. Unfortunately, we can't trap the normal gem5 co-processor entry in KVM (it doesn't seem to be possible to trap accesses to non-existing co-processors). We therefore use BZJ instructions to cause a trap from virtualized mode into gem5. The BZJ instruction is becomes a normal branch to the gem5 fallback code when running in simulated mode, which means that this patch does not need to change the ARM ISA-specific code. Note: This requires a patched host kernel.
2013-03-25x86: Revert [02321b16685f] which breaks m5ops on x86Andreas Sandberg
Changeset 02321b16685f added m5_writefile to m5op_x86.S a second time, which causes a compilation error on when compiling for x86. This changeset reverts that changeset and fixes the error.
2013-01-08util: add writefile to m5 util program for x86Lluís Vilanova
2013-01-08util: add m5_fail op.Lluís Vilanova
Used as a command in full-system scripts helps the user ensure the benchmarks have finished successfully. For example, one can use: /path/to/benchmark args || /sbin/m5 fail 1 and thus ensure gem5 will exit with an error if the benchmark fails.
2013-01-07util: Fix stack corruption in the m5 utilAndreas Sandberg
The number of arguments specified when calling parse_int_args() in do_exit() is incorrect. This leads to stack corruption since it causes writes past the end of the ints array.

2012-10-09m5: Expose m5 pseudo-instructions to C/C++ via a static libraryJames Clarkson
Updated the util/m5/Makefile.arm so that m5op_arm.S is used to create a static library - libm5.a. Allowing users to insert m5 psuedo-instructions into their applications for fine-grained checkpointing, switching cpus or dumping statistics. e.g. #include <m5op.h> void foo(){ ... m5_reset_stats(<delay>,<period>) m5_work_begin(<workid>,<threadid>); ... m5_work_end(<workid>,<threadid>); m5_dump_stats(<delay>,<period>); }

2011-09-13gem5ops: Implement Java JNI for gem5OpsPrakash Ramrakhyani
These ops allow gem5 ops to be called from within java programs like the following: import jni.gem5Op; public class HelloWorld { public static void main(String[] args) { gem5Op gem5 = new gem5Op(); System.out.println("Rpns0:" + gem5.rpns()); System.out.println("Rpns1:" + gem5.rpns()); } static { System.loadLibrary("gem5OpJni"); } } When building you need to make sure classpath include gem5OpJni.jar: javac -classpath $CLASSPATH:/path/to/gem5OpJni.jar HelloWorld.java and when running you need to make sure both the java and library path are set: java -classpath $CLASSPATH:/path/to/gem5OpJni.jar -Djava.library.path=/path/to/libgem5OpJni.so HelloWorld
