PCSX2 bug(s)?

IPU_Fifo.cpp
- IPU_Fifo_Output::write

Code:
        uint transsize = min(size, 8 - (uint)ipuRegs.ctrl.OFC);
        if(!transsize)
            return 0;

#if 1
        // new code?
        ipuRegs.ctrl.OFC += transsize;
#else
        // old code
        ipuRegs.ctrl.OFC = transsize;
#endif

        size -= transsize;

If OFC = 7 (output FIFO count), it'll only write 1 qword to FIFO (8 = full).

Old code will set OFC = 1 Excl instead of max 8 (full).


Don't know if this fixes anything but something I've noticed.
(and noticed that IPU_Fifo_Input::write looks okay)

Time Crisis 2 boot

Code:
        case 0x08:  // STATUS
            CDVD_LOG("cdvdRead08(Status) %x", cdvd.Status);
#if 1
            // Time Crisis 2 - checks spin flag
            if( cdvd.Spinning )
                return cdvd.Status | CDVD_STATUS_SPIN;
            else
#endif
            return cdvd.Status;
            break;

        case 0x0A:  // STATUS
            CDVD_LOG("cdvdRead0A(Status) %x", cdvd.Status);
#if 1
            // Time Crisis 2 - checks spin flag
            if( cdvd.Spinning )
                return cdvd.Status | CDVD_STATUS_SPIN;
            else
#endif
            return cdvd.Status;
            break;

We get toasted on PS1 -all the time- because of this. Combinations of status flags (read + spin together in particular).

You'll notice the 'CDVD Fast hack' is no longer needed. And the Standby slamming goes away.



edit:
Other than 1394 -1 barfs, not sure where 'Loading' problem is. Likely cdrom again. Smile

Not so sure why game would use an 'Break' abort? (that's new for me)

Break is usually used if a command is taking too long, maybe as you saw the spin status is used in conjunction with reading, but there youve made it always spin, so its trying to abort that command..

good finds tho! especially the ipu one, that could explain a lot!

It happens when you get into the main menu. Note that cdvdRead08(Status) logging is _before_ the spin flag hack is used.

This didn't help though:
if( cdvd.Spinning && cdvd.Reading )

Break happens with(out) the CDVD fast hack.

Just leaving around notes for you guys (until I find something else that may be borking your emu).

Good work!
Will definitely check this out when I have some time.

If you have anymore of these CDVD tips by chance, we could really use them.
As you may know by now, the thing is totally undocumented and everyone just guesses how it should work Tongue2

All the Shin Megami games use CDVD Break seemingly as part of their normal operation btw.

Code:
DvdRead: Reading Sector 31946(16 Blocks of Size 2064) at Speed=4x
DvdRead: Reading Sector 31962(16 Blocks of Size 2064) at Speed=4x
DvdRead: Reading Sector 31978(16 Blocks of Size 2064) at Speed=4x
CDVD Break Call
DvdRead: Reading Sector 31991(16 Blocks of Size 2064) at Speed=4x
DvdRead: Reading Sector 206164(16 Blocks of Size 2064) at Speed=4x
CDVD Break Call
DvdRead: Reading Sector 206176(16 Blocks of Size 2064) at Speed=4x
DvdRead: Reading Sector 31986(16 Blocks of Size 2064) at Speed=4x
CDVD Break Call
DvdRead: Reading Sector 31990(16 Blocks of Size 2064) at Speed=4x
DvdRead: Reading Sector 31992(16 Blocks of Size 2064) at Speed=4x
CDVD Break Call

I believe the driver calls break whenever a full file is read.

Also I'd like to ask if you guys ever had PSX games overwrite IOP memory by reading a disk too quickly?
In our case it's the games Tales of the Abyss, which really doesn't like short seek times.
If the seeks in some locations are below like 5 seconds, some IOP stuff dies (we assume it's overwriting wrong memory here).

Hello,

shalma is undergoing one of his two-five year hiatus vacations (burnout a few times already). Tongue2

I think he didn't know that. I'll tell him though! Laugh

Uhm.. g.

I remember working with him on Gundam Battle Assault 2 + InuYasha + Hokuto no Ken 2.

We had a problem where the CdlPause time was way too fast. Game was decompressing (case #1) and didn't have time to finish = crash.

case #2 was a timing issue and battles not starting.
case #3 was gpu transfer time and garbled up.

Team Buddies has problem with too fast cd timing (..?) - doesn't make it too menus (does in his debugger build though). Fade to Black uses roughly 'precise' 1/75x timing (too slow 1/74 = crash, too fast 1/76 = crash). Didn't care to understand why.

For case 1-3 above, we used 'guess' time of 4 * 1/75x read length. Same for CdlPause. Except for seek 0 - must be 0 time.


He also talked privately to me about your PCSX2 CdlPause not having ack - complete IRQ phases? (you just have ack) This chewed up >> several psx games also like FF7 (ack = 2 read cycles, complete = 0 or 4 read cycles if game does double pause).


I'll ask him later. He wanted to test around with Xebra cdrom but never cared enough.

Very interesting stuff! We need as much info on cdvd (cd should give good clues on how it'll react), it's such an unknown yet it causes so much bother lol

He made a few comments about cd -> cdvd:

1) Irq_CommandComplete

He thought he saw 'Irq_Acknowledge' but it Complete. Which works on PS1 he said except for some games that specifically check for Ack - Complete (like RE2).


2) CDVD_LOG( "CDVD read finished, DMA3 done" );

This bothered him a bit but he didn't investigate. PS2 seems to autopause by itself.

The PS1 has autopause reading but almost no one used it (Lode Runner did but not required). So it normally goes like this without autopause:
reads - seek time - ack (needed by a few games regardless of seek time)
read 1x - data ready
read 1x - data ready
pause - ack (2/75 seems right) - complete (~4/75 works)
(edit: he's not sure if PS1 autopause throws ack)


It's the lack of 'autopause' time in PCSX2 'read finished' code that makes him uneasy. PCSX2 just immediately stops with 'Complete' after the last block is read.

Something he still thinks about.


3) ReadTD time

2 PS1 games read tracks beyond the TOC limit (ex. Need for Speed reads track 02 when it has 1 track). Game wants 0:2:0 returned for all 'invalid' tracks.

He didn't think it would fix anything but it was worth mentioning (if cdrom plugin works but not cdiso).


Side-note:
He also said Guncom 2 FMV jigsaw puzzle is not PCSX2 IPU bug. It's GSdx (ZZOgl works okay). Something about memory alignment he thought.



If there was a more 'complete' list of possible CDVD game bug descriptions hanging around the SVN somewhere, maybe he'd revisit a few more again when he feels better. It's how we did bugs with PCSX1 - a sticky colored post-it board (really!).

I'll nag him again some other time about TC2. Laugh
