wierd ini files. The ini files are still used as an intermediate step,
but a sophisticated python library exists to help build them more
easily.
SConscript:
add the new embedded file stuff
remove all of the old object description junk
base/inifile.cc:
base/inifile.hh:
get rid of findDefault and findAppend since they were the source
of much evil.
base/trace.cc:
For now, if we don't have the dprintf_stream set up, dump
to standard out. We probably want a command line option
for this.
dev/alpha_console.cc:
PioDevice now takes a platform parameter.
All PioDevices must have a pio_latency parameter. We stick
a dummy parameter in here for now until we get rid of the
builder stuff.
dev/alpha_console.hh:
don't need Platform anymore
dev/baddev.cc:
PioDevice now takes a platform parameter.
All PioDevices must have a pio_latency parameter. We stick
a dummy parameter in here for now until we get rid of the
builder stuff. Same for the platform parameter, though we just
pass the PioDevice a null parameter since it isn't used by
this device and it's quicker.
dev/baddev.hh:
fix #include guards
dev/etherlink.cc:
rename parameters.
dev/ethertap.cc:
rename parameters
dev/ide_ctrl.cc:
All devices need an address even if it will get overwritten later.
dev/ide_disk.cc:
use an enum for the drive ID stuff.
rename disk_delay -> delay
Actually, I think that we should implement "cable select" and
have the controller tell the drive what it is.
dev/io_device.cc:
dev/io_device.hh:
All IO devices take a Platform *
dev/ns_gige.cc:
all devices need an io_bus. rename header_bus to io_bus
We don't need stuff for the interrupt controller since
it's all in the platform now.
dev/ns_gige.hh:
We don't need stuff for the interrupt controller now since
it's all in the platform.
dev/pciconfigall.cc:
Pass a dummy NULL to the PioDevice for the platform since
we don't need one.
dev/pcidev.cc:
Move a bunch of common functionality into the PciDev
dev/platform.hh:
remove unneeded code
dev/tsunami.cc:
remove unused param
dev/tsunami_cchip.cc:
pass platform pointer
dev/tsunami_io.cc:
dev/tsunami_pchip.cc:
dev/uart.cc:
pass platform variable
dev/uart.hh:
don't need to keep a platform pointer. it's in the base class
kern/linux/linux_system.cc:
kern/tru64/tru64_system.cc:
rename some parameters
sim/builder.cc:
clean up builder code. use more parameters from the
config node. all sections with a type= are now created,
the old mechanisms no longer work
sim/builder.hh:
remove some extra variables since they are found in the ConfigNode
sim/main.cc:
add a quick hack command line argument -X to dump out the
embedded files. (probably should be fixed up a little.)
accept .mpy files
printing to the streams has to happen after the hierarchy
is built since we're moving away from param contexts
sim/param.cc:
add parsing support for ranges
sim/process.cc:
isValid isn't very useful anymore. interpret the names
stdout, stderr, cout, cerr for the file descriptors
sim/pyconfig/SConscript:
Add Action handlers for creating an embedded python file
and for creating an embedded C file.
use these action handlers to embed all objects found in the objects
tree into the binary along with the importer and the m5config stuff
sim/pyconfig/m5config.py:
Major changes to the original configuration file generator. These
changes largely involve implementing copy-on-write like semantics
for all of the SimObjects. Real documentation must be written.
sim/universe.cc:
Universe becomes a SimObject since we don't really have the notion of
param contexts in the python code.

/*
|
|
* Memory mapped interface to the system console. This device
|
|
* represents a shared data region between the OS Kernel and the
|
|
* System Console.
|
|
*
|
|
* The system console is a small standalone program that is initially
|
|
* run when the system boots. It contains the necessary code to
|
|
* access the boot disk, to read/write from the console, and to pass
|
|
* boot parameters to the kernel.
|
|
*
|
|
* This version of the system console is very different from the one
|
|
* that would be found in a real system. Many of the functions use
|
|
* some sort of backdoor to get their job done. For example, reading
|
|
* from the boot device on a real system would require a minimal
|
|
* device driver to access the disk controller, but since we have a
|
|
* simulator here, we are able to bypass the disk controller and
|
|
* access the disk image directly. There are also some things like
|
|
* reading the kernel off the disk image into memory that are normally
|
|
* taken care of by the console that are now taken care of by the
|
|
* simulator.
|
|
*
|
|
* These shortcuts are acceptable since the system console is
|
|
* primarily used doing boot before the kernel has loaded its device
|
|
* drivers.
