separate the rx thread and tx thread and get rid of the dedicated flag.
dev/ns_gige.cc:
dev/ns_gige.hh:
dev/ns_gige_reg.h:
python/m5/objects/Ethernet.py:
dedicated flag goes away, we have new individual flags for
rx thread and tx thread
dev/sinic.cc:
Virtualize sinic
- The io registers are replicated many times in memory, allowing the NIC to
differentiate among several virtual interfaces.
- On the TX side, this allows multiple CPUs to initiate transmits at the same
time without locking in the software. If a partial packet is transmitted,
then the state machine blocks waiting for that virtual interface to complete
its packet. Then the state machine will move on to the next virtual
interface. The commands are kept in fifo order.
- On the RX side, multiple partial transmits can be simultaneously done.
Though a packet does not deallocate its fifo space until all preceeding
packets in the fifo are deallocated. To enable multiple receives, it
is necessary for each virtual nic to keep its own information about its
progress through the state machine.
dev/sinic.hh:
Virtualize sinic
Receive state must be virtualized since we allow the receipt of packets in
parallel.
dev/sinicreg.hh:
Virtualize sinic

add support for delaying pio writes until the cache access occurs
dev/sinicreg.hh:
Add delay_read and delay_write to the register information struct
for now, we won't delay any reads, and we'll delay the writes that
initiate DMAs
python/m5/objects/Ethernet.py:
add a parameter to delay pio writes until the timing access
actually occurs.

interrupts.
dev/sinic.cc:
- The prepareRead function sets all the variables in the register
file that depend on various state bits that change on the fly.
Includes RxDone, RxWait, TxDone, and TxWait
- Use the new register information accessor functions to grab
validity and size information for the read and write functions
- read all registers directly from the register space by offset
and size, not by actual name (less code)
- The side effect of reading the interrupt status (clearing it) now
happens outside the actual chunk of code where the value is loaded.
- Add an iprRead function for when we may want speculative access
to device registers through an ipr or special instruction.
- When RxData or TxData are written, their busy flag is set to
indicate that they have an outstanding transaction.
- The RxHigh and TxLow interrupts are special, they only interrupt
if the rxEmpty or txFull limits were hit
- Move reset to the command register
- Update more registers on reset, clear rxEmpty and txFull
- Data dumps only happen if EthernetData trace flag set
- When a DMA completes, kick the other engine if it was waiting
- implement all of the new interrupts
- serialize the new stuff
dev/sinic.hh:
- Put all registers with their proper size and alignment into
the regs struct so that we can copy multiple at a time.
- Provide accessor functions for accessing the registers with
different sizes.
- Flags to track when the rx fifo hit empty and the tx fifo became
full. These flags are used to determine what to do when below
the watermarks, and are reset when crossing the watermark.
- the txDmaEvent should actually trigger the txDmaDone function
- Add an iprRead function for when we may want speculative access
to device registers through an ipr or special instruction.
- The prepareRead function sets all the variables in the register
file that depend on various state bits that change on the fly.
- add rx_max_intr and dedicated (for dedicated thread) config params
dev/sinicreg.hh:
Add some new registers: Command, RxMaxIntr, RxFifoSize, TxFifoSize,
rename XxThreshold to XxFifoMark
Move Reset to the Command register
Add Thread to the Config register
New interrupts, better names
More info in RxDone and TxDone

the nsgige state machine can run. The frequency is of the actual
state transitions, and not the rate of what underlying
instructions might run at.
dev/ns_gige.cc:
Implement a state machine clock that acutally limits how fast
the state machine can run. After each state transition, a
variable is kept to hold the next state transition until the
next clock. The frequency is of the actual state transitions,
and not the rate of what underlying instructions might run at.

Special mpy importer is gone; everything is just plain
Python now (funky, but straight-up).
May not completely work yet... generates identical ini
files for many configs/kernel settings, but I have yet
to run it against regressions. This commit is for my
own convenience and won't be pushed until more testing
is done.
python/m5/__init__.py:
Get rid of mpy_importer and param_types.
python/m5/config.py:
Major cleanup. We now have separate classes and
instances for SimObjects. Proxy handling and param
conversion significantly reorganized. No explicit
instantiation step anymore; we can dump an ini file
straight from the original tree.
Still needs more/better/truer comments.
test/genini.py:
Replace LoadMpyFile() with built-in execfile().
Export __main__.m5_build_env.
