ec8661f431 Fix a damn silly bug. On some occasions, we could have spcflags() set to
EXEC_RETURN | HANDLE_INTERRUPT. And then, we handled the interrupt, but
EXEC_RETURN was set so we returned very quickly without completing the
interrupt routine. As a side effect, this occasionnaly hung the emulator
most likely with {ethernet,audio}-based applications that trigger a lot
of interrupts.

The fix is to always honour EXEC_RETURN flag at first, of course.

fd69df24f3 Re-enable spinlocks on {i386,x86_64} since they are now used only for really
small atomic operations (add/sub). This implementation should be enough for
that purpose.

08c5f8b713 Improve idle wait mechanism. Now, the emulator thread can be suspended
(idle_wait) until events arrived and notified through TriggerInterrupt().
i.e. we no longer sleep a fixed amount of time on platforms that support
a thread wait/signal mechanism.

55f5e3a41b Fix CR save/restore in EmulOp thunk. I don't know what it fixes for real
but that was definitely wrong to only preserve CR2 there.

ea42af0568 Consume the packet even if we could not allocate a message block for it in
the Ethernet interrupt. The BeOS version does that, likewise for MOL. Otherwise,
we end up into an infinite loop reporting the memory allocation failure.

I think this is now the expected behavior as we wouldn't have stats
(num_rx_no_mem) for it if we couldn't get out of the EtherIRQ. ;-) Besides,
the packet will be resent for reliable networks.

38d03d02e9 The alternate stack trick never worked as you can't modify an active stack.
i.e. it returned EPERM and ran into stack corruption to eventually crash the
emulator. This is noticeable in !hw_mac_cursor_accl mode (e.g. fullscreen DGA).

In order to the sigalstack() to be effective, we must kludge the kernel to
think it's running on another stack. In practise, we provide another stack
for the SIGUSR2 handler. sigusr2_handler_init() fulfills that purpose.

I hope this fixes remaining issues forever. At some point, I had multiple
*_init() handlers in case this is necessary.

a8ba24aecf Use fast spinlocks only for small enough atomic operations. Otherwise, you
run into some performance problems in e.g. video graphics experience because
of busywaits in the current spin_lock() implementation.

52138d2014 We HAVE_PTHREADS even if we use our own pthreads implementation, this also
induces availability of locking primitives. I will merge the !HAVE_PTHREADS
case (a la Basilisk II) for EMULATED_PPC when I get back to home.

d0da2a0dda - Restore TOC on EMUL_OP_EXEC_RETURN from Execute68k
- Restore r13 on EMUL_RETURN, though I never saw r13 clobbered
- Increase stack frame allocated to EmulOp processing on par with BeOS
- Factor GetResource wrappers with a macro + restore r13 too

26ee263b6f Don't fake the TVECT value on non-BeOS native systems. This is important
for systems that use a global r2 as the TLS register, e.g. Linux/ppc with
newer glibc. Also remove the syscall junk which were simply workarounds
for this bug. Remove a duplicate r2 restoration in EmulOp.

BTW, it's possible to get SheepShaver running on Linux/ppc systems with
NPTL rather than SheepThreads.

fe99211e75 Support USE_CPU_EMUL_SERVICES in SDL/video driver. Only trigger ethernet
interrupt in one_tick() if no pthreads at all are used, i.e. ether_dummy
is effective in that case. Otherwise, don't trigger ethernet again if
pthreads are available (and ether_unix) and cpu emul services are active.

957bee00cf Always allocate RAM and ROM areas at the same time. This avoids having ROM
suddenly allocated below RAM and thus not working. Besides, this may fix a
latent deallocation bug in real addressing mode (i.e. release the whole
block allocated at once, not separately).

Side effect: this makes Basilisk II work in direct addressing mode with JIT
on Darwin 8.0.1 for x86.
