Method fields description[edit | edit source]

What is considered as rsx fifo commands is really combination of few fields describing so called "method". Single method description is 32 bit, and contain flags, addresses, and count of parameters.

Bits View (MSB:LSB) Description

Flag: Call
03:13 
000XXXXX XXXXXX00 00000000 00000000
Method count, since count is left shifted by 2 you can consider count as byte count & 0x1FFC
16:29 
00000000 00000000 AAABBBBB BBBBBB00
Method register (2 bits right-shifted)
03:31 
000XXXXX XXXXXXXX XXXXXXXX XXXXXXXX
Jump offset
00:29 
XXXXXXXX XXXXXXXX XXXXXXXX XXXXXX00
Call offset (2 bits right-shifted)

Note: It seems to be possible to write continuous registers using single write with multi param count. Eg. gcmInit write 0x00080384 to setup NV4097_SET_DEPTH_BOUNDS_MIN and NV4097_SET_DEPTH_BOUNDS_MAX using one command with two 4 bytes params.

SCE DRIVER These methods are executed by the LV1, not by the RSX.

Method registers[edit | edit source]

The method register field consists of two fields: A 3-bit long subchannel identifier and a 11-bit long offset in that channel. At driver user-level, the whole 14-bit field can be considered as nothing but a 2-bit-rightshifted address where data goes in, optionally triggering an event.

NV40_CHANNEL_DMA[edit | edit source]

These methods are executed by the PFIFO puller itself, instead of being forwared to an engine.

Register (whole 14 bit) Name Description
0x0050 NV406E_SET_REFERENCE Modify DMA control's reference register
0x0060 NV406E_SET_CONTEXT_DMA_SEMAPHORE DMA context object
0x0064 NV406E_SEMAPHORE_OFFSET Offset has to be smaller than 0x1000 and 4-aligned.
0x0068 NV406E_SEMAPHORE_ACQUIRE Make the PFIFO puller wait until offset contains the parameter.
0x006C NV406E_SEMAPHORE_RELEASE Write parameter to the specified offset.

libgcm Functions[edit | edit source]

cellGcmGetControlRegister[edit | edit source]

  • Returns EA of FIFO registers: PUT, GET and REF

cellGcmFlush[edit | edit source]

  • Kicks FIFO command processing by moving PUT register

cellGcmFinish[edit | edit source]

  • This function adds FIFO command for setting REF register to value 0xFFFFFFFF, kicks FIFO and then loops and checks REF register until it is set to value 0xFFFFFFFF.
  • It just waits until all FIFO commands are processed by GPU.

cellGcmGetFlipStatus[edit | edit source]

  • Returns flip status.
  • Checks bit 31 in word at offset 0x10C0 + 0x1 * 0x40 of reports area returned by lv1_gpu_context_allocate.
  • Flip status = ((word at 0x10C0 + 0x1 * 0x40) >> 31) ^ 0x1.
  • Flip status: 0 - flip done, 1 - flip waiting

cellGcmResetFlipStatus[edit | edit source]

  • Resets flip status.
  • Sets flip status to flip waiting.
  • Sets bit 31 to 0 in word at offset 0x10C0 + 0x1 * 0x40 of reports area returned by lv1_gpu_context_allocate.

Equivalent to: 

lv1_gpu_context_attribute(context handle, 0x10a, 0x1 /* id */, 0x7fffffff /* mask */, 0x0 /* value */, 0x0)

Small Test[edit | edit source]

Here is a FIFO program i executed on Linux: 

0x00040060     # set semaphore DMA context method
0x66616661     # DMA object handle
0x00040064     # set semaphore offset method
0x00000400     # semaphore offset
0x0004006C     # semaphore release method
0xf00dbeef     # semaphore value

And here is dump of reports area: 

000003f8: 0x1337beef
000003fc: 0x1337f001
00000400: 0xf00dbeef   # semaphore value
00000404: 0x1337babe
00000408: 0x1337beef
0000040c: 0x1337f001
  • As you see releasing semaphore writes 0xf00dbeef to reports area at offset 0x400.
