Emulator

It never happened to me. I use r4883.

Hm....perhaps there is a bad memory access in a thread which is hiding the real issue
or something. I once tracked one down like this that ended up being a buffer overflow
in the dsp plugin...quite annoying to find.

However, unless someone can reproduce this there's really nothing to do.

hm, he's right. With dual core unchecked, games crash dolphin when booting now.

I can't reproduce this either, so it could be system or OS specific.

nope, I just tested a bit and it seems to be game specific. e.g. Mario Kart Wii, Dead
Space Ex., Mario Party 8, Fatal Frame 4, NSMB, etc.
Also CG: Z:TP, Mario Party 4, MP1&2, etc.

Well, maybe there are several factors shrug
Using Win7 64bit. recent dolphin revs 64bit.

I have this problem with Wii Big Brain Academy and the System Menu 4.2u also. I
actually reported this in issue 2038, but I didn't know at the time of reporting it
was being caused when the dual core option was unchecked.

I am using Ubuntu 9.10 linux 64bit and the latest dolphin revisions. This began on
the commit to revision 4854 if that helps.

Issue 2038 has been merged into this issue.

Issue 2106 has been merged into this issue.

Issue 2143 has been merged into this issue.

I've narrowed down the problem to these routines: asm_routines.pairedStoreQuantized

I am not familiar with the SSE instruction-set and so I cannot debug it any further
than this.

The single core crash does not occur in Interpreter mode.

BTW: single core crash doesn't occur on 32 Bit OS.

i'm running on win7 64bit .I have 7 games but only the game 'Arc Rise Fantasia' crashed
when single core is used .

so far, it only crashes on windows x64 (it seems like linux isn't affected either)
and it was introduced in r4854.

glenric is using linux x64 and it happens to him (see comment above).

My guess is that there is a state problem involving the x64 registers between the
asm_routines.pairedStoreQuantized and the video plugin vertex loader. I cannot think
of any other reason why this might be happening under these circumstances.

i also tested it using dolphin 32bit version on 64 bit windows 7 and single core works
fine .Therefore , only 64 bit version running on 64 bit windows will crash .

Issue 2097 might be related after all?
Some testing revealed that the same patch as Sonic did for OSX (r4897) works, infact
with even less (only disabling LoadStorePaired does the trick).

I'm still using R4869 as it is the fastest build for me and I can confirm this problem.

Win 7 X64.

@Jack can we disable it on 64 bit on coming release? or is it like major slow down?
(I would suggest even disabling it completely for all platforms...)

nakee: Can't say anything about that, my reasoning was mainly based on observation of
experiences people had on Linux and OSX - I haven't got any crashes lately, on Win7
x64 with DC, not bothering to use SC when DC works.
Gonna see if I can find out other things about it, but I don't really know. I'd let
other people comment on it that tried out both things - crashing and working with the
patch in Issue 2097.

Well, it at least seems to fix the SC Crash I get with Harvest Moon - Magical Melody;
other games work or dont make heavy use of Paired ops until where i checked.
I can't say whether setting bJITLoadStorePairedOff = true in general has any
noticeable impact on performance, since I don't have any comparable experiences with
it disabled.

How about
#ifdef _M_X64
if (!Core::g_StartupParameters.bCPUOnThread) { Default(inst; return; }
#endif
for psq_st and psq_l (both Jit and JitIL)?

j4ck.fr0st, I agree with using that patch and putting a TODO comment in, so we
remember to come back to this one.

Try now. I have doubts about my fix though.

Still crashing using single core on 64-bit r5063 on a Intel Core i7 920 HT enabled
with Windows 7 Ultimate 64-bit. This is an issue that needs to be fixed as some games
run poorly when dual core is enabled.

Please, WHAT GAMES are crashing? I currently cannot reproduce it, and thus, I cannot
debug and fix it.

one of the game i tested which will crash when using x64 + single core is Arc Risa
Fantasia JAP.

Games I've tested to be crashing with single core:

Bomberman Land
Mario Kart Wii
NSMB
Wii Play
Wii Sports
Super Mario Galaxy
Zelda TP

As mentioned earlier, Harvest Moon: Magical Melody also crashes (for me at least).

To add some more value to this issue, skid and i were discussing this on IRC
yesterday. It seems that the main problem is the vertex loader, which appearently
uses the same set of registers. With single core, those regs are shared, and a
context switch during a paired store will mess them up. Dual core doesnt have this
problem, since both run on separate threads.

I'm going to take a look into an earlier trace I had, since my crashes always showed
up inside the vertex manager, where address (being passed by reference) suddenly
became 0, while a stack further up it was non zero. Might turn out to be nothing of
worth at all, but thats my next thing to look into.

Wii music crashes with dual core option unchecked.

nakeee: linux still has this problem why did you merge the issue?
