|
Bug fixes:
|
|
|
|
|
1. Fix SE serialization
|
|
|
|
|
2. SPARC_FS booting with TimingSimpleCPU
|
|
|
|
|
3. Rename cycles() to ticks()
|
|
|
|
|
4. Various SPARC ISA fixes
|
|
|
|
|
5. Draining code for checkpointing
|
|
|
|
|
6. Various performance improvements

|
|
|
2007-11-02 02:07:49 +01:00
|
|
|
Possible Incompatibilities:
|
|
|
|
|
1. Real TLBs are now used in SE mode. This is more accurate however it could
|
|
|
|
|
cause some problems if you've modified the way page handling is done in
|
|
|
|
|
SE mode.
|
|
|
|
|
2. There have been many changes to the way the SCons files work. SimObjects,
|
|
|
|
|
sources files, and trace flags are all specified in the SConscript files.
|
|
|
|
|
To see how to add your sources take a look at one of them.
|
|
|
|
|
3. Python is now used to created the parameter structs that were created
|
|
|
|
|
manually before. The parameters listed in a py file are turned into
|
2007-11-02 02:18:08 +01:00
|
|
|
a header file with the same name (e.g. BadDevice.py -> BadDevice.hh).
|
|
|
|
|
With this change the structs can be populated automatically and the
|
2007-11-02 02:07:49 +01:00
|
|
|
ugly macros to define and create SimObjects at the bottem of source
|
|
|
|
|
files are gone. The parameter structs also automatically inherit
|
|
|
|
|
parameters from their parents.

|
coherence). We are working to address these limitations and hope to
