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

d8a33b0952 Direct Color visual is OK for fbdev dga. 2005-06-24 22:31:28 +00:00
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.

c33f09b2d8 Fix crash in FBDev DGA mode when it failed to initialize (here, that was

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.

5810c6a764 Use "screen TYPE/WIDTH/HEIGHT" prefs item by default on Unix systems. The

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.

663facbf97 Fix native Linux/ppc with recent enough glibc that supports TLS; r2 is used 
in that case. Tell me if I broke other arches, e.g. r13 is no longer saved
in Video and Ethernet stubs, though it seems to be OK.

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

6c0e2a9f2a Disable MacOS -> X11 copying of cursor in windowed mode too. You can 
recompile with "mac_cursor_enabled" constant set to true. Disabling it
causes a better looking cursor that is not "disappearing" sometimes with
e.g. Microsoft Internet Explorer.

ba7bfc478e Extend NativeOp count to 64 (6-bit value), aka fix NATIVE_FILLRECT opcpdes. 
Translate NQD_{bitblt,fillrect,invrect} to direct native calls.
Use Mac2HostAddr() for converting Mac base address to native.

be little-endian and 64-bit safe.

b4ac3fb507 Basic fillrect/invrect NQD. Code may need to be factored out somehow. 
Verify that bitblt NQD transfer modes are really CopyBits() ones [MB5].
