SWARM Change Log

#00061 michael pp Michael Dales (michael@dcs.gla.ac.uk) Thu Sep 27 10:41:39 BST 2001
------------------------------------------------------------------------------------
Contains lots of code by Hanish Menon [www.hanishkvc.com] to enable uCLinux to
work on SWARM. Here is a list of his changes:

* Working on uClinux, I found that Interrupts where getting disabled even thou
  they had been enabled, when working on Interrupt handlers. 
  Looking further on I found that for LDMxx instructions which use PC and sets 
  S bit, it doesn't restore CPSR from the required SPSR. So I have added a fix
  to DecodeMRTLoad function to take care of it. Its based on my preliminary 
  analysis of the SWARM code logic, so have to verify for absolute correctness 
  later.

* The SWI implementation provided by SWARM has been put in a 
  #ifdef SWARM_EXTRA_FEATURES block, 
  has it was conflicting with uClinux's swi implemenation. And also has its not
  part of any standard ARM processor.

* A simple debugger logic added. It allows one to set a breakpoint, dump 
  state of processor core and coprocessors. Step thro one or more instructions
  at a time. As part of it, added NextPC, DebugDumpCore and DebugDumpCoProc
  functions.

* Before calling the BarrelShifter logic, the shift distance was being checked
  to be less than 32 using a ASSERT statement, I have replaced it and made a
  message come up when ever it occurs.

* If the memory address accessed is greater than the available memory, then
  instead of quiting, I made it continue after showing the Processor DebugDump.
  Maybe we should have it generate some exception, is it Data or Prefetch abort?

* Added debug info regarding IRQ Disable bit and the busCurrentIRQ status.
  The debug info added to intctrl and ostimer have been put like other
  debug info within #ifndef QUIET blocks.

* And finaly uClinux-arm kernel 2.4.4-xxx is working on swarm to a great extent.
  Increased the Memory size to 12 MB from 10 MB, Giving 10 MB to applications 
  and ramdisk. Remaining goes to kernel roughly, have to fit it better a bit, 
  later.

* Updated my UART Ctrl logic to use a PseudoTTY instead of the previous
  logic where the stdin/stdout of SWARM was used has the interface to the 
  UART, which was ugly has stdin/stdout of SWARM is used for other purposes
  also.

  As a result of this fix you can communicate to the UART on SWARM by
  using the minicom or any other program which allows one to communicate 
  with a serial or terminal logic. The slave pseudo terminal to communicate
  with will be /dev/pts/XXX

* Looking into uClinux, I realized that the IntCtrl in Swarm maintains 
  the Interrupt Pending status only till the Device requesting the Interrupt
  keeps the IRQ line active. And the OSTimer which currently uses the IRQ
  mechanism inturn holds the IRQ request to IntCtrl only for one cycle.
 
  So rather than updating the OSTimer to hold the Request till the driver
  acknowledges to OSTimer, I updated the IntCtrl logic such that It maintains
  the Interrupt in a Pending state until the driver clears the corresponding
  Pending bit in the IntCtrl. The idea above being that with this mechanism, 
  each and every device which use Interrupt mode of operation doesn't have 
  to worry about holding the request till the driver acknowledges, instead 
  the IntCtrl takes care of this automatically.

* Looked into the Device/Pheriperal BUS definition and Usage logic and
  based on it updated the same for the pheriperals that I added.
  - Updated UART Ctrl bus definition to remove the RESET pin and 
    Reduce the Interrupt Pins from 4 to 1. This single interrupt 
    pin will be used later to notify the system about the status 
    of the Transmit and Recieve buffers or FIFOs.
  - Updated LCD Ctrl bus definition to remove the RESET pin and
    Reduce the Interrupt Pins from 4 to 1. This single interupt
    pin will be used to notify the system about any LCD Ctrl 
    related events.
  - Corrected a comment regarding OSTimer.addr pins.
* Updated the logic in armproc.cpp wrt UART and LCD Ctrls so that
  they can rise interrupts to the Interrupt Ctrl if required.
* Updated certain messages and return values.

* Added the srec loader
* Updated the LCD controller address

* ReIntroduced the Parse_Opts logic.
* Will be adding support for SREC file loading.
* Fixed a problem in the bin/Makefile 

* Added support for a minimal UART controller.
* Updated the earlier sample LCD controller which I had written wrt its Addr.

* Looking into SWARM and the Device/Pheriperal interface logic in SWARM
* Added a partial LCD Ctrl logic to test the interface logic

In addition I updated a few things in his code to fix a problem he'd 
highlighted with ldms.

------------------------------------------------------------------------------------
Added a large amount to the minimal libc implementation, to enable madplay mp3
player to compile for SWARM. Extended the default amount of memory to 10 meg 
to give madplay enough memory in which to work. Added code to pass extra 
params given to SWARM to the test application running on swarm. Started to 
add bits for proper MMU - but halted due to other demands on my time.

------------------------------------------------------------------------------------
Lots of changes here. Firstly added an OS timer and an interrupt controller
to the processor model. These are based on those in the Intel SA-1110. In
addition to interrupt handling, I had to add memory mapped devices to the 
processor model. Because of all the mode changing with interrupts, I was 
forced to tidy up my test app run time environment to make use of modes
(hither to everything ran in SVC mode...).

Added code to turn a swi call to SWARM that had an invalid number to 
generate a UDT, and for instructions with a cond code of 0xF to also
generate a UDT.

First pass at adding interrupts (IRQ and FIQ). Interrupts are always delayed
by cache reads and multi-cycle instructions. Simple IRQ/FIQ handler which
prints a message and then returns to the main code.

Changed SWARM so that on a bad address error, SWARM will dump the register
contents for the processor core and any coprocessors. Not fully tested - 
I fear that there is a legacy bug in CDisarm - but at the moment I'm busy
will applications, so I'll tidy it up later.

First working coprocessor!!!! It's not the prettiest piece of logic every,
but it works. I'm a tocuh tired, so I may try and improve on it at some
point, but essentially it just works. The system coprocessor register 0xB
includes the cycle counter. Test5 has the rpcc macro to read the value
of the cycle counter into a C variable. Funky. Think I just wore out
my copy of Kid A getting this to work :-)

Fixed bugs in both caches and byte writes. Note that accessing a swi upcall
into SWARM now flushes the cache(s) - this needs a better solution, but
it works for now. This was a problem if you did a read into a the stack
for instance. Byte writes were broken too, but I fixed that.

Much improved version. Now started to use the ARM gcc and some munging to 
produce binaries to run in SWARM. This has lead to some features being added
(e.g. mov pc, *) and a slew of bugs being found. In the test_apps dir is
a simple libgcc to link raw apps against. Not quite libc, but better than
a kick in the teeth :-)

Started to add Load/Store multiple, but it's wrong. Store works, but it doesn't
do it like it should. The datapath needs a bit of reworking. This checkin is
basically to allow me to revert if I break too much while trying to fix it.
