H A D | system.hh | 8527:6bac5b04d588 Fri Aug 19 16:08:00 EDT 2011 Ali Saidi <Ali.Saidi@ARM.com> ARM: Mark some variables uncacheable until boot all CPUs are enabled. There are a set of locations is the linux kernel that are managed via cache maintence instructions until all processors enable their MMUs & TLBs. Writes to these locations are manually flushed from the cache to main memory when the occur so that cores operating without their MMU enabled and only issuing uncached accesses can receive the correct data. Unfortuantely, gem5 doesn't support any kind of software directed maintence of the cache. Until such time as that support exists this patch marks the specific cache blocks that need to be coherent as non-cacheable until all CPUs enable their MMU and thus allows gem5 to boot MP systems with caches enabled (a requirement for booting an O3 cpu and thus an O3 CPU regression). 8286:abc8ab4ddd93 Wed May 04 21:38:00 EDT 2011 Ali Saidi <Ali.Saidi@ARM.com> ARM: Add support for loading the a bootloader and configuring parameters for it 8285:c38905a6fa32 Wed May 04 21:38:00 EDT 2011 Prakash Ramrakhyani <Prakash.Ramrakhyani@arm.com> ARM: Implement WFE/WFI/SEV semantics. 8229:78bf55f23338 Fri Apr 15 13:44:00 EDT 2011 Nathan Binkert <nate@binkert.org> includes: sort all includes |

Ruby overwrites the senderState pointer with another pointer. The pointer is restored only when Ruby gets done with the packet. LSQ makes use of senderState just after sendTiming() returns. But the dynamic_cast returns a NULL pointer since Ruby's senderState pointer is from a different class. Storing the senderState pointer before calling sendTiming() does away with the problem. 8581:56f97760eadd Thu Sep 22 21:59:00 EDT 2011 Steve Reinhardt <steve.reinhardt@amd.com> event: minor cleanup Initialize flags via the Event constructor instead of calling setFlags() in the body of the derived class's constructor.

Only create a memory ordering violation when the value could have changed between two subsequent loads, instead of just when loads go out-of-order to the same address. While not very common in the case of Alpha, with an architecture with a hardware table walker this can happen reasonably frequently beacuse a translation will miss and start a table walk and before the CPU re-schedules the faulting instruction another one will pass it to the same address (or cache block depending on the dendency checking). This patch has been tested with a couple of self-checking hand crafted programs to stress ordering between two cores. The performance improvement on SPEC benchmarks can be substantial (2-10%). 8481:818aea9960f5 Sun Jul 31 22:21:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> O3: Implement memory mapped IPRs for O3. 8272:82057507f2f9 Wed May 04 21:38:00 EDT 2011 Ali Saidi <Ali.Saidi@ARM.com> O3: Fix a small corner case with the lsq hazard detection logic. 8247:acf4b902c02e Wed Apr 20 22:07:00 EDT 2011 Nathan Binkert <nate@binkert.org> stats: one more name violation 8232:b28d06a175be Fri Apr 15 13:44:00 EDT 2011 Nathan Binkert <nate@binkert.org> trace: reimplement the DTRACE function so it doesn't use a vector At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing.

This change pulls the instruction decoding machinery (including caches) out of the StaticInst class and puts it into its own class. This has a few intrinsic benefits. First, the StaticInst code, which has gotten to be quite large, gets simpler. Second, the code that handles decode caching is now separated out into its own component and can be looked at in isolation, making it easier to understand. I took the opportunity to restructure the code a bit which will hopefully also help. Beyond that, this change also lays some ground work for each ISA to have its own, potentially stateful decode object. We'd be able to include less contextualizing information in the ExtMachInst objects since that context would be applied at the decoder. Also, the decoder could "know" ahead of time that all the instructions it's going to see are going to be, for instance, 64 bit mode, and it will have one less thing to check when it decodes them. Because the decode caching mechanism has been separated out, it's now possible to have multiple caches which correspond to different types of decoding context. Having one cache for each element of the cross product of different configurations may become prohibitive, so it may be desirable to clear out the cache when relatively static state changes and not to have one for each setting. Because the decode function is no longer universally accessible as a static member of the StaticInst class, a new function was added to the ThreadContexts that returns the applicable decode object. 8229:78bf55f23338 Fri Apr 15 13:44:00 EDT 2011 Nathan Binkert <nate@binkert.org> includes: sort all includes |

H A D | isa_parser.py | 8588:ef28ed90449d Tue Sep 27 02:48:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Use '_' instead of '.' to delimit type modifiers on operands. By using an underscore, the "." is still available and can unambiguously be used to refer to members of a structure if an operand is a structure, class, etc. This change mostly just replaces the appropriate "."s with "_"s, but there were also a few places where the ISA descriptions where handling the extensions themselves and had their own regular expressions to update. The regular expressions in the isa parser were updated as well. It also now looks for one of the defined type extensions specifically after connecting "_" where before it would look for any sequence of characters after a "." following an operand name and try to use it as the extension. This helps to disambiguate cases where a "_" may legitimately be part of an operand name but not separate the name from the type suffix. Because leaving the "_" and suffix on the variable name still leaves a valid C++ identifier and all extensions need to be consistent in a given context, I considered leaving them on as a breadcrumb that would show what the intended type was for that operand. Unfortunately the operands can be referred to in code templates, the Mem operand in particular, and since the exact type of Mem can be different for different uses of the same template, that broke things. 8538:b324639974f6 Thu Sep 08 06:21:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Don't look for operands in strings. 8537:00df5058a557 Thu Sep 08 06:20:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Match /* */ and // style comments.

This makes implementing an include statement as part of a grammar possible. 8449:4be49ad47c74 Tue Jul 05 19:52:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Define operand types with a ctype directly. 8448:86ed97566b23 Tue Jul 05 19:48:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Simplify operand type handling. This change simplifies the code surrounding operand type handling and makes it depend only on the ctype that goes with each operand type. Future changes will allow defining operand types by their ctypes directly, convert the ISAs over to that style of definition, and then remove support for the old style. These changes are to make it easier to use non-builtin types like classes or structures as the type for operands. 8339:1810956fa5dc Tue Jun 07 03:46:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Loosen the regular expressions matching filenames. The regular expressions matching filenames in the ##include directives and the internally generated ##newfile directives where only looking for filenames composed of alpha numeric characters, periods, and dashes. In Unix/Linux, the rules for what characters can be in a filename are much looser than that. This change replaces those expressions with ones that look for anything other than a quote character. Technically quote characters are allowed as well so we should allow escaping them somehow, but the additional complexity probably isn't worth it. 8176:46f5d6391f99 Thu Mar 24 13:55:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Set up op_src_decl and op_dest_decl for pc operands. 7816:b5003ac75977 Sat Jan 08 00:50:00 EST 2011 Steve Reinhardt <steve.reinhardt@amd.com> scons: show sources and targets when building, and colorize output. I like the brevity of Ali's recent change, but the ambiguity of sometimes showing the source and sometimes the target is a little confusing. This patch makes scons typically list all sources and all targets for each action, with the common path prefix factored out for brevity. It's a little more verbose now but also more informative. Somehow Ali talked me into adding colors too, which is a whole 'nother story. |

By using an underscore, the "." is still available and can unambiguously be used to refer to members of a structure if an operand is a structure, class, etc. This change mostly just replaces the appropriate "."s with "_"s, but there were also a few places where the ISA descriptions where handling the extensions themselves and had their own regular expressions to update. The regular expressions in the isa parser were updated as well. It also now looks for one of the defined type extensions specifically after connecting "_" where before it would look for any sequence of characters after a "." following an operand name and try to use it as the extension. This helps to disambiguate cases where a "_" may legitimately be part of an operand name but not separate the name from the type suffix. Because leaving the "_" and suffix on the variable name still leaves a valid C++ identifier and all extensions need to be consistent in a given context, I considered leaving them on as a breadcrumb that would show what the intended type was for that operand. Unfortunately the operands can be referred to in code templates, the Mem operand in particular, and since the exact type of Mem can be different for different uses of the same template, that broke things. 8449:4be49ad47c74 Tue Jul 05 19:52:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Define operand types with a ctype directly. 8442:b1f3dfae06f1 Sun Jul 03 01:34:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA: Use readBytes/writeBytes for all instruction level memory operations. 8229:78bf55f23338 Fri Apr 15 13:44:00 EDT 2011 Nathan Binkert <nate@binkert.org> includes: sort all includes |

Restore the System get/setMemoryMode methods, and use this mechanism to specialize SimObject as well, eliminating teh need for sim_object.i. Needed bits of sim_object.i are moved to the new pyobject.i. Also sucked a little SimObject specialization into cxx_param_decl() allowing us to get rid of src/sim/sim_object_params.hh. Now the generation and wrapping of the base SimObject param struct is more in line with how derived objects are handled. 8295:221013f9fd2f Thu May 12 14:19:00 EDT 2011 Nathan Binkert <nate@binkert.org> stats: better expose statistics to python.

This code is like a set of ranges. I'm using it to keep track of changed lines in source code, but it could be use to keep track of memory ranges and holes in memory regions. It could also be used in memory allocation type stuff.

This distinguished them from the read and write functions which handled higher level data types. Because those functions don't exist any more, this change renames readBytes and writeBytes to more general names, readMem and writeMem, which reflect the fact that they are how you read and write memory. This also makes their names more consistent with the register reading/writing functions, although those are still read and set for some reason. 8443:530ff1bc8d70 Sun Jul 03 01:34:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ExecContext: Get rid of the now unused read/write templated functions. 8277:bfaab04cb292 Wed May 04 21:38:00 EDT 2011 Ali Saidi <Ali.Saidi@ARM.com> CPU: Add some useful debug message to the timing simple cpu. 8276:66bb0d8ae8bf Wed May 04 21:38:00 EDT 2011 Ali Saidi <Ali.Saidi@ARM.com> CPU: Fix a case where timing simple cpu faults can nest.

This turns out to be very useful when building code from an EXTRAS directory using SCons's -C option. We were trying to do this with targets but it didn't actually work since we didn't update BUILD_TARGETS (so SCons got confused internally). We weren't even trying with EXTRAS. To simplify the code, the default target is also interpreted relative to the launch dir even though it was explicitly handled as relative to the m5 dir before... I doubt anyone really uses this anyway so it didn't seem worth the complexity. (Maybe we should get rid of it?) 8267:06f3a4cbd585 Mon May 02 03:40:00 EDT 2011 Steve Reinhardt <steve.reinhardt@amd.com> scons: allow use of current builds as default build settings Currently the --default= option only looks at the predefined build configs (in m5/build_opts), so you're limited to basing a new build config off of those (ALPHA_SE, etc.).
