2017-12-04misc: Rename misc.(hh|cc) to logging.(hh|cc)Gabe Black
These files aren't a collection of miscellaneous stuff, they're the definition of the Logger interface, and a few utility macros for calling into that interface (panic, warn, etc.).

2017-12-04misc: Move the ExitLogger class definition into misc.ccGabe Black
This class isn't referred to outside of misc.hh, and isn't necessarily useful outside of the particular logging setup implemented in misc.cc. The Logger class itself is different since it provides a generic interface that can be used with different logging schemes.

2017-12-04tests: Remove trietest's dependence on cprintf.Gabe Black
Dumping the structure of the tries being constructed was useful for debugging when the trie data structure was being developed, but the output can't be automatically verified easily, and what's considered correct depends on the specific implementation of the trie itself. To make some of the earlier tests more meaningful, additional lookups were added which verified that the correct values were returned when the nodes of the trie were in particular arrangements.

2017-12-01arm: Enable ns registers access in secure modeGiacomo Travaglini
Arm security extension introduced register banking between secure and non-secure mode. This has been removed in armv8 using AArch64 in EL3, where the decoded register is by default the non-secure version. Using non-secure register infos(flags) was preventing secure execution to access the register with the MRC/MCR at EL1. The patch updates the following banked registers' flags so that their non-secure version can be accessed in secure mode: MISCREG_CSSELR, MISCREG_SCTLR, MISCREG_ACTLR, MISCREG_TTBR0, MISCREG_TTBR1, MISCREG_TTBCR, MISCREG_DACR, MISCREG_DFSR, MISCREG_IFSR, MISCREG_ADFSR, MISCREG_AIFSR, MISCREG_DFAR, MISCREG_IFAR, MISCREG_PAR, MISCREG_PRRR, MISCREG_MAIR0, MISCREG_NMRR, MISCREG_MAIR1, MISCREG_AMAIR0, MISCREG_AMAIR1, MISCREG_VBAR, MISCREG_CONTEXTIDR, MISCREG_TPIDRURW, MISCREG_TPIDRURO, MISCREG_TPIDRPRW, MISCREG_CNTP_TVAL, MISCREG_CNTP_CTL, MISCREG_CNTP_CVAL For those registers the following permission bits have been set: MISCREG_PRI_S_RD MISCREG_PRI_S_WR Change-Id: Ib881c526e75d69e313f8ef66eb78fc704de6bf59 Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-by: Giacomo Gabrielli <giacomo.gabrielli@arm.com> Reviewed-on: https://gem5-review.googlesource.com/6201 Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>

2017-11-27scons: Switch from "guards" to "tags" on source files.Gabe Black
Tags are just arbitrary strings which are attached to source files which mark them as having some property. By default, all source files have the "gem5 lib" tag added to them which marks them as part of the gem5 library, the primary component of the gem5 binary but also a seperable component for use in, for example, system C. The tags can be completely overridden by setting the "tags" parameter on Source, etc., functions, and can be augmented by setting "add_tags" which are tags that will be added, or alternatively additional tags. It's possible to specify both, in which case the tags will be set to the union of tags and add_tags. add_tags is supposed to be a way to add extra tags to the default without actually overriding the default. Both tags and add_tags can be a list/tuple/etc of tags, or a single string which will be converted into a set internally. Other existing tags include: 1. "python" for files that need or are used with python and are excluded when the --without-python option is set 2. "main" for the file(s) which implement the gem5 binary's main function. 3. The name of a unit test to group its files together. 4. Tags which group source files for partial linking. By grouping the "tags" into a single parameter instead of taking all extra parameters as tags, the extra parameters can, in the future, be passed to the underlying scons environment. Also, the tags are either present or not. With guards, they could be present and True, present and False, or not present at all.

These classes are just used as base classes for other instructions and don't need to be part of the ISA definition. Pull them into standard C++ files.

Change the definition of PMU events in order to integrate events not cannot easily be represented by probe points. The software increment event is now defined as a special type with its separate implementation in pmu.cc and pmu.hh.

2017-11-21cpu, cpu, sim: move Cycle probe updateJose Marinho
Move the code responsible for performing the actual probe point notify into BaseCPU. Use BaseCPU activateContext and suspendContext to keep track of sleep cycles. Create a probe point (ppActiveCycles) that does not count cycles where the processor was asleep. Rename ppCycles to ppAllCycles to reflect its nature.
