| 2009-04-26 | X86: Implement lowest priority interrupts more correctly. | Gabe Black | |
| Lowest priority interrupts are now delivered based on a rotating offset into the list of potential recipients. There could be parasitic cases were a processor gets picked on and ends up at that rotating offset all the time, but it's much more likely that the group will stay consistent and the pain will be distributed evenly. | |||
| 2009-04-26 | X86: Tell the function that sends int messages who to send to instead of ↵ | Gabe Black | |
| figuring it out itself. | |||
| 2009-04-26 | X86: Make the local APICs register themselves with the IO APIC. | Gabe Black | |
| This is a hack so that the IO APIC can figure out information about the local APICs. The local APICs still have no way to find out about each other. Ideally, when the local APICs update state that's relevant to somebody else, they'd send an update to everyone. Without being able to do a broadcast, that would still require knowing who else there is to notify. Other broadcasts are implemented using assumptions that may not always be true. | |||
| 2009-04-26 | X86: Record the initial APIC ID which identifies an APIC in M5. | Gabe Black | |
| The ID as exposed to software can be changed. Tracking those changes in M5 would be cumbersome, especially since there's no guarantee the IDs will remain unique. | |||
| 2009-04-26 | X86, Config: Make makeX86System consider the number of CPUs, and clean up ↵ | Gabe Black | |
| interrupt assignment. | |||
| 2009-04-24 | SPARC: Tighten up the clone system call and SPARCs copyRegs. | Gabe Black | |
| 2009-04-23 | request: reorganize flags to group related flags together. | Steve Reinhardt | |

| flags. | |||
| 2009-04-22 | stats: expose statistics to python | Nathan Binkert | |
| 2009-04-22 | stats: Move flags into info.hh and use base/flags.hh to manage the flags | Nathan Binkert | |
| 2009-04-22 | stats: Shuffle around info stuff so it can be accessed separately | Nathan Binkert | |
| 2009-04-22 | stats: Rename the info classes to hopefully make things a bit clearer | Nathan Binkert | |
| FooInfoBase became FooInfo FooInfo became FooInfoProxy | |||
| 2009-04-22 | stats: update reference outputs now that compatibility is gone | Nathan Binkert | |
| Because of the initialization bug, it wasn't consistent anyway. | |||
| 2009-04-22 | stats: remove simplescalar compatibility for printing | Nathan Binkert | |
| 2009-04-22 | stats: fix initialization bug in distribution text output | Nathan Binkert | |
| 2009-04-22 | i8254xGBe: major style overhaul. | Steve Reinhardt | |
| Moved DescCache template functions from .hh to .cc file. Also fixed lots of line-wrapping problems, and some irregular indentation. | |||
| 2009-04-22 | Update stats for new single bad-address responder. | Steve Reinhardt | |
| Mostly just config.ini updates, though the different response latency for bad addresses caused very minor timing changes in the O3 Linux boot tests. | |||
| 2008-07-16 | mem: use single BadAddr responder per system. | Steve Reinhardt | |
| Previously there was one per bus, which caused some coherence problems when more than one decided to respond. Now there is just one on the main memory bus. The default bus responder on all other buses is now the downstream cache's cpu_side port. Caches no longer need to do address range filtering; instead, we just have a simple flag to prevent snoops from propagating to the I/O bus. | |||
| 2009-04-21 | scons: Rename the basic environment from env -> main. | Nathan Binkert | |
| env is used as a local variable all over the place and sometimes it is easy to get confused as to whether the global env or local env is being used. This will become especially important when I change the way we support our variants. | |||
| 2009-04-21 | scons: Fix two problems with the way that the library path is generated. | Nathan Binkert | |
| 1) -L is automatically added, so don't do it ourselves 2) prepend the paths for gzstream and libelf so they are certain to come first. The problem is that python might add /usr/lib to the path and the user might have a locally installed version of libelf installed. | |||
| 2009-04-21 | Automated merge with ssh://m5sim.org//repo/m5 | Nathan Binkert | |
| 2009-04-21 | pseudo: only include kernel stats if FULL_SYSTEM. | Nathan Binkert | |
| 2009-04-21 | arm: include missing file for arm | Nathan Binkert | |
| 2009-04-21 | arm: Unify the ARM tlb. We forgot about this when we did the rest. | Nathan Binkert | |
| This code compiles, but there are no tests still | |||
| 2009-04-21 | rundiff: flush stdout after each diff | Steve Reinhardt | |
| 2009-04-21 | scons: make default target work again | Nathan Binkert | |
| 2009-04-21 | Set up m5threads tests on classic (non-ruby) memory system. | Steve Reinhardt | |
| Just one test (40.m5threads-test-atomic) is set up for now. These tests require that the m5threads SPARC binaries are present in /dist or in test-progs. | |||
| 2009-04-21 | syscall_emul: style fixes (mostly wrapping overly long lines) | Steve Reinhardt | |
| 2009-04-21 | syscall: Resolve conflicts between m5threads and Gabe's recent SE changes. | Steve Reinhardt | |
| 2009-04-21 | Commit m5threads package. | Daniel Sanchez | |
| This patch adds limited multithreading support in syscall-emulation mode, by using the clone system call. The clone system call works for Alpha, SPARC and x86, and multithreaded applications run correctly in Alpha and SPARC. | |||
| 2009-04-21 | SCons: Export export_vars so SConsopts files can add to them | Nathan Binkert | |
| 2009-04-21 | Minor tweaks for future Ruby compatibility. | Steve Reinhardt | |
| 2009-04-21 | request: add PREFETCH flag. | Steve Reinhardt | |
| 2009-04-20 | request: rename INST_READ to INST_FETCH. | Steve Reinhardt | |
| 2009-04-20 | request: split public and private flags into separate fields. | Steve Reinhardt | |
| This frees up needed space for more public flags. Also: - remove unused Request accessor methods - make Packet use public Request accessors, so it need not be a friend | |||
