2019-03-19util: Build m5 with -no-pie flagRyan Gambord
Added -no-pie flag to link /util/m5 to support newer versions of GCC that enable PIE by default. Tested for backwards compatibility with GCC 4.3, which, only warns for the unrecognized flag.

2018-09-26util: Do not use $(PWD) in MakefilesKevin Brodsky
644e8cdf5ee7 ("util: Move the m5ops.h file to a shared directory") added include/ to the include path for m5 Makefiles, based on $(PWD): $(PWD)/../../include. Unfortunately, this breaks when using `make -C <path>`, as -C does not move PWD accordingly. The fix is simply to remove $(PWD), as a relative path is just fine here.

The header file with C declarations for m5ops is sometimes needed by code outside of the util/m5 directory. Move this file to the shared include directory and factor out flags to a generic asm header.

2016-10-26dev: Add m5 op to toggle synchronization for dist-gem5.Michael LeBeane
This patch adds the ability for an application to request dist-gem5 to begin/ end synchronization using an m5 op. When toggling on sync, all nodes agree on the next sync point based on the maximum of all nodes' ticks. CPUs are suspended until the sync point to avoid sending network messages until sync has been enabled. Toggling off sync acts like a global execution barrier, where all CPUs are disabled until every node reaches the toggle off point. This avoids tricky situations such as one node hitting a toggle off followed by a toggle on before the other nodes hit the first toggle off.

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: 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.
