found today.

733cfc784b * A bunch of changes which get us closer to running the sample. 1998-02-24 23:37:20 +00:00

b4d2f483b3 * PKE sim unit testing continuing. Starting to run milestone sample.
* sky-pke.h (PKE_MEM_READ): Removed "read" entry from FIFO trace.

	* sky-pke.c (pke_attach): Set trace file to line buffering iff
 	open.
	(pke_io_read_buffer, pke_io_write_buffer): Handle erroneous
 	reads/writes by zero-padding.
	(pke_io_write_buffer): Switch to more bit-field definition macros.
	(pke_issue): Remove "stalled" entry from FIFO trace.
	(pke_pc_advance): Correct logic for DMA-tag-skipping, PKEcode
 	classification.
	(pke_code_mskpath3): Sketch of possible PATH3 masking method.
	(pke_code_mpg): Keep order of lower/upper VU words as supplied.
	(pke_code_unpack): Logic change for wl/cl/num unpacking.  Weird.

653c259005 * PKE sim unit testing continuing. The DIRECT and MPG instructions
were hammered in today's runs.  Work is beginning in endian-proofing
  the code.

	* sky-pke.c (pke1_issue): Issue on correct PKE device.
	(pke_io_write_buffer, pke_code_mpg, pke_code_unpack): Perform more
 	endian conversions.
	(pke_code_mpg, pke_code_direct): Add operand alignment assertions.
	(pke_code_mpg): Correct VU stall checks.  Correct VU opcode
 	transfer ordering.
	(pke_code_direct): Correct typos in DIRECT operand accessing.
	(pke_code_unpack): Correct conditional sign-extension handling.

	* sky-gpuif.c (gif_io_read_buffer, gif_io_write_buffer): Correct
 	assertion polarity.
	(gif_read_tag): Disable faulty DMA-tag testing code.

534a3d5cf1 * Continuing unit testing of PKE simulator. It now successfully matches
the SCEI PKE simulator's output on its own test sample (tsv432.in).

	* sky-pke.h (PKE_MEM_READ, PKE_MEM_WRITE, PKE_REG_MASK_SET): Add
 	trace file records.

	* sky-pke.c: (pke_track_write): Removed function.  Replaced with
 	in-line modifications to VU tracking tables.
	(pke_attach): Attach VU tracking tables.  Use line buffering on
 	trace files.
	(pke_issue): Spit out additional trace records.
	(pke_pc_operand_bits): Correct bitfield masking error.
	(*): Replace sim_read/write with kludge PKE_MEM_READ/WRITE
 	throughout.
	(pke_code_unpack): Correct numerous small bugs in operand decoding
 	etc.

e23069923b * Started PKE sim unit testing. A number of minor errors were corrected.
A few PKE instructions even run correctly!  Next missing function of
  interest: FIFO pruning.

	* sky-pke.c (pke_issue): Take extra SIM_DESC argument.
	(pke_attach): Attach correct PKE0/PKE1 device.  Open trace file if
 	VIF{0,1}_TRACE_FILE env. var. is defined.
	(pke_io_write_buffer): Classify words in FIFO quadword.  Use
 	kludgey sim_core routines to access DMA registers.
	(pke_pc_advance): Add PKEcode classification.  Correct DMA tag
 	skipping.  Emit trace records.
	(pke_pc_fifo): Add PKEcode operand classification.
	(pke_check_stall): Perform stall checks against updated register
 	scheme.
	(pke_code_unpack): Correct operand-count calculation.
	(pke_code_stmask): Correct instruction skipping.

	* sky-pke.h (PKE_MEM_WRITE, PKE_MEM_READ): New kludge macros.
	(BIT_MASK_BTW): Corrected off-by-one error.
	(enum wordclass): Classify words in a FIFO quadword.

	* sky-dma.c (dma_io_read_buffer): Correct address checking assertions.

	* sky-engine.c (engine_run): Pass along SIM_DESC to PKE
 	instruction issue code.

3733e09fb6 DMA define names changed (SRCADDR -> MADR). 1998-02-18 16:47:03 +00:00

db6dac32c7 - PKE simulation almost finished. Needed enhancements:
* trace file generation
  * FIFO pruning

- PKE functions still missing due to external dependencies:
  * interrupt to 5900 (igen?)
  * VU busy checking (sky-vu / coprocessor registers)
  * PATH3 masking (sky-gpuif / covert control interface)

8f9acca317 First functional drop of the gpuif code plus modifications to
non-gpuif code to allow sky sim to build with --enable-sim-warnings

43a6998b41 - PKE simulation code almost complete. Still missing:
* handling of super duper packed UNPACK arguments
  * skipping of in-progress instruction on break/stop
  * interrupt generation to 5900
  * PATH2/PATH3 status checking & masking
  * ability to write to FIFO one word (instead of quadword) at a time

fba9bfed2d - Added almost all code needed for PKE0/1 simulation. Considers
clarifications given in SCEI question/answer batches #1 and #2.

803f52b9dc Second pass at moving sky files into mips dir,
prepend sky- to all #include's of sky headers.
