df960a814e HFS+ is case insensitive (sic!). At least, it pointed out to not remove 
ppc_asm.s file but rather the temporary ppc_asm.out.s variant.

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.

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.

gbeauche
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.

0f4440f99f Handle "screen fbdev/WIDTH/HEIGHT" to force use of FBDev DGA instead of XF86 
DGA mode. In other words, root user can now use FBDev DGA though it's always
recommended to run SheepShaver with a normal user. Increase "ramsize" bounds
in the GUI and fully migrate to new "screen" modes. Remove "windowmodes" and
"screenmodes" defaults.

d27832cb1c - Implement fullscreen DGA via fbdev access under Linux. Besides, r/w access 
to /dev/mem is required on Linux to use XF86 DGA mode. Otherwise, there is
now a fallback to fbdev.
- Forward port some features from Basilisk II (set_window_name,
disable_mouse_accel).
- Don't SIGSTOP the emulation thread on suspend since that would completely
stop the process on Linux. Use a frame buffer lock instead (as B2 does)

0db0d48bf0 Avoid the use of floating-point when loading/storing from/to memory. This 
could have caused some rounding thus alterations to integer registers on
context switches when lfd/stfd instructions were used. e.g. cygwin compilers
defaulted to i686 code generation and exhibed this behaviour, you could also
see this behavior with -march=i586 -mtune=pentiumpro. GCC is perfectly right
to do those optimizations.

Colateral feature: SheepShaver should now run on Linux/ppc64 with relevant
32-bit runtime. Native Linux/ppc64 support is harder as low mem globals are
32-bit in mind and e.g. the TLS register there is %r13, %r2 is the TOC
