Overview

The program measures the DMA controller beyond what the register descriptions give: register read-back, transfer times for each device, the CPU's share of the bus while a transfer runs, chopping, channel priority and the DICR interrupt flags. Each group writes its results to its own file.1

Times are counted on root counter 2, which counts system clock cycles. A time runs from the CHCR write that starts a channel to the first poll that sees CHCR bit 24 clear, so every figure includes a fixed overhead for the write and the poll. A CHCR write that starts no transfer reads 68 clocks on the card-h run. Rows that could exceed 131071 clocks use root counter 2 on system clock / 8 and are given here in system clocks.12

The groups that can hang the console run last, each in a separate program image, so that a hang loses only that row. The variants dmatime_drq1 to drq10, odd1 to odd4, pio1 to pio5 and unk1 to unk3 each hold one such row.1

Results

Register Read-back

With each channel's DPCR enable off, MADR keeps 24 bits: FFFFFFFFh reads 00FFFFFFh. BCR keeps all 32 bits. CHCR on channels 0 to 5 keeps the bits 71770703h, and the same register reads back at offset +Ch. A halfword or byte store to BCR or CHCR writes only its own lanes: halfword 1234h at +2 reads 12340000h.3

Channel 6 CHCR keeps only bits 30, 28 and 24 of a write, and bit 1 always reads 1, so FFFFFFFFh reads 51000002h. DPCR keeps every bit. DICR keeps bits 0 to 5 and bits 15 to 23. Bit 31 cannot be written, and writing bit 15 sets bit 31 at once.3

1F8010F8h read 7FE7581Ah and 1F8010FCh read 00FFFFFFh. Writing 0 or FFFFFFFFh to either changes nothing. 1F8010F8h does change between transfers: it read 7FE31AA3h after an OTC and 7FE70AA3h after an SPU read, and it changed during an SPU write.4

OTC (Channel 6)

An OTC transfer takes about one system clock a word plus the overhead, and about 1.06 clocks a word for long tables. BCR 0 clears 65536 words, which took the same time as 65535. MADR and BCR keep their start values after the transfer, and the CPU polled once during each.2

Table 1: OTC transfer time on the card-h run
Words System clocks
1 89
16 109 to 119
64 157
256 359
1024 1172
4096 4429 to 4434
16384 17461 to 17468
65535 69585 to 69601
65536 69586 to 69601

CHCR bit 30 changes nothing in the time, and it stays set after the transfer. The upper half of BCR is ignored in SyncMode 0.2

An OTC that counts down past address 0 stops at the wrap. Three words from address 4 wrote 0 at address 4 and 00FFFFFCh at address 0, and left the word at 1FFFFCh unchanged.5

GPU (Channel 2)

A GPU list costs about 10 clocks for each empty node. The CPU runs between nodes: a list of 2048 empty nodes took 21040 clocks and the CPU polled 1064 times during it. Each GP0 word in a node adds about 1.07 clocks, so 16 nodes of 255 words took 4612 to 4628 clocks.6

A list ended by FFFFFFh ends without an error. A list ended by FFFFFEh or 800000h sets DICR bit 15 and with it bit 31 and IRQ3, and MADR is left holding the end value.7

A 2048-word block write to VRAM in SyncMode 0 takes 2247 clocks. SyncMode 1 in blocks of 16 words takes 512 to 517 clocks for 16 blocks and 7126 to 7153 for 256 blocks, and smaller blocks cost more: 256 blocks of 1 word took 2978 clocks. Reads from VRAM are slower than writes in SyncMode 1. A read of 64 blocks of 16 words took 2235 clocks against 1855 for the write.8

With GP1(04h) set to 0 the GPU does not request data, and a SyncMode 0 or 1 transfer stays busy until GP1(04h)=2 is written. With CHCR bit 28 set, a SyncMode 0 transfer runs to the end even with the request off.9

SPU (Channel 4)

SPU transfers are much slower than GPU transfers. A SyncMode 0 write of 256 words took 2141 clocks, which is about 8 clocks a word. In SyncMode 1 the first block of 16 words took 217 to 221 clocks and each further block about 1160, so 64 blocks took about 73070 clocks. Reads take about the same time as writes. Changing the SPU delay register between 200931E1h, 220931E1h, 220931F1h and 22093141h moved the 16-block time by less than 1000 clocks.10

64 words were written to sound RAM and read back. After SyncMode 1 transfers 56 words matched, and after SyncMode 0 transfers 16 matched.10

With the SPU transfer mode set to stop, a SyncMode 0 or 1 transfer stays busy until the mode is set to DMA write. With CHCR bit 28 it runs to the end.11 During a SyncMode 1 SPU write, MADR advances and BCR counts down one block at a time, and the CPU polls between blocks.12

CPU During a Transfer

A loop running from the instruction cache keeps running during an OTC burst. A loop of registers alone or of scratchpad loads finished in the time of the loop or of the transfer, whichever was longer: 4000 turns took 17402 clocks with an OTC of 16384 words, and 10000 turns took 40019 with and without it. The timer read at the end waits for the transfer.13

Loops that use the bus wait for the transfer. 1000 turns of RAM stores took 21390 clocks with the OTC against 4019 alone, and RAM loads and CHCR loads added the full transfer time. During a SyncMode 1 SPU write, register loops ran at full speed and RAM loads ran about 15 percent slower.13

Chopping

Chopping a 2048-word GPU block write in SyncMode 0 lets the CPU run between pieces of the transfer. MADR advances and BCR counts down while it runs, and they end at the last address and 0. The time depends on both windows.14

Table 2: 2048-word GPU write with chopping in system clocks (CPU polls)
DMA window (words) CPU window 1 clock 4 clocks 16 clocks 32 clocks 128 clocks
1 16720 (1040) 23376 (1548) 47888 (3412) 80680 (6141) 276648 (20471)
2 9440 (513) 13400 (1023) 24640 (1706) 41000 (3069) 139208 (10231)
4 5864 (266) 7352 (511) 13472 (1022) 21856 (1533) 70704 (5111)
16 3136 (127) 3504 (127) 5032 (254) 7088 (381) 19280 (1271)
128 2352 (15) 2408 (15) 2576 (30) 2792 (45) 4240 (151)

The same write without chopping takes 2247 clocks with one poll. A 256-word SPU write chopped at 16 words and 64 clocks took 3206 clocks against 2138 unchopped.14

Priority

Two channels were armed with their DPCR enables off and then started by one DPCR write, both writing the same 64 words. In SyncMode 0 the channel with the higher priority (the lower number) ran first and the other channel's data was left in memory. At equal priority, channel 6 ran before channel 4 and before channel 2.15 DPCR bits 28 to 30 made no difference to an SPU write or to a CPU loop running beside it.15

DICR Interrupts

A channel's flag is set at the end of its transfer when its enable bit (16+n) is set, whether or not bit 23 is set. Bit 31 and IRQ3 follow only when bit 23 is set as well. Writing 1 to a flag clears it.16

Table 3: DICR around a 16-word OTC on the card-h run
DICR written DICR after the OTC IRQ3
00000000h 00000000h 0
00400000h 40400000h 0
00800000h 00800000h 0
00C00000h C0C00000h 1
00FF0000h C0FF0000h 1
00008000h 80008000h 0
0000003Fh 0000003Fh 0

IRQ3 is raised when bit 31 changes from 0 to 1. A flag set while bit 23 was off raised IRQ3 as soon as bit 23 was written, and a second flag while bit 31 was already set raised nothing.16

CHCR Bits 8 29 and 30

Bit 30 stays set in CHCR after a transfer. A 16-block GPU write took 476 to 480 clocks with it against 494 without, and a 16-block SPU write 17355 against 17700. Bit 8 in a list transfer changes nothing. A forced SyncMode 0 burst with bit 29 set runs to the end, and CHCR reads 30000001h after it.17

Bit 8 in SyncMode 1 runs last because it may stop the DMA. On the card-b run the log ends at that row with no result.18

Expansion Port (Channel 5)

DMA5 from the expansion port at 1F000000h never ends in SyncMode 0 or 1 without bit 28: the channel was still busy after 20000 polls. With bit 28 it runs, at about 20 clocks a word: 1 word took 111 to 115 clocks and 64 words 1380 to 1388. With nothing in the port, every word read FFFFFFFFh.19

List End Timing

Short GPU lists ending FFFFFFh took 65 clocks for one empty node and 98 for four. Writing DICR 7F000000h before the transfer changed only the first sample of the first row. That sample read 75 clocks against 65.20

DICR around a 16 word OTC (channel 6: enable bit 22, flag bit 30). psx-spx sets the flag only with bit 23 and bit 22 (dmachannels.txt:184-186), nocash with bit 22 alone (channels.txt:122-123). IRQ3 is I_STAT bit 3, acknowledged before each OTC.
