gbeauche	6eacaf2e82	Fix asm clobbers for newer gcc 4.0.1, don't use -msse to enable xmm clobbers ... (likewise for -mmmx vs. mmx registers). Instead, since GCC won't generate MMX/SSE code without explicit intrinsics use of vectorization, we know those register won't be clobbered outside of the __asm__ code. So, it's safe as is (we could also remove all sse/mmx clobbers).	2005-07-09 21:53:26 +00:00

gbeauche	0f358518df	New paranoia checks that better match was SheepShaver is doing with threads ... and sigaltstack(). At least, this time we force use of threads and also alter r1 to see whether the current threading model relies on it or not.	2005-07-04 06:09:59 +00:00
gbeauche	29207d9cf2	Move sigregs handling to dedicated header	2005-07-04 05:34:33 +00:00

gbeauche	811b8d6648	Bad MacOS X, we need our our semaphore.h from Basilisk II to get POSIX ... unnamed semaphores emulation with named Mach semaphores.	2005-07-03 22:44:30 +00:00
gbeauche	97eaae096c	Fix typo for AO_transmit_packet() thunk.	2005-07-03 22:43:11 +00:00
gbeauche	e259aeb504	Tweaks to build slirp on MacOS X. Yeah, there is now ethernet there! ;-)	2005-07-03 22:42:48 +00:00
gbeauche	f346839f86	Add the complete NDRV variant for DIRECT_ADDRESSING modes. We could use ... this one for all cases but I'd prefer keep it that way. i.e. the old driver in REAL_ADDRESSING mode (with the D(bug()) facility), and the new NDRV for DIRECT_ADDRESSING mode (e.g. Windows).	2005-07-03 22:04:18 +00:00
gbeauche	97726bd1e7	Minor tweaks to support compilation of ether.cpp within MacOS. i.e. mostly ... migrate the Ethernet driver to the MacOS side. This is enabled for DIRECT_ADDRESSING cases. I didn't want to alter much of ether.cpp (as it would have required to support that mode). Of course, in REAL_ADDRESSING mode (the default) and for debugging purposes, the old driver is still available.	2005-07-03 22:02:01 +00:00
gbeauche	9c16ab1514	Remove obsolete and broken Cygwin/X11 hacks. Forbid builds of the Windows ... version from within the Unix/ directory.	2005-07-03 13:39:06 +00:00
gbeauche	b7004b1199	Add necessary configury + support code to support slirp in SheepShaver, ... the user-space network emulation layer. Enable it on all Unix supported platforms where I know it works.	2005-07-03 13:05:36 +00:00
gbeauche	2cf7fd2a88	First round of patches to increase ethernet code portability.	2005-07-03 08:23:42 +00:00
gbeauche	029d86ce4c	Fix build with CodeWarrior in MacOS (9 under SheepShaver ;-)	2005-07-02 22:54:07 +00:00
gbeauche	7cc1bbc7b8	Issue a SysError(dsOldSystem) if we are trying to use MacOS < 8.1.0 with a ... NewWorld ROM. That may be 8.1.0 included but original iMac had a NewWorld ROM compatible system. Otherwise we will crash because the boot routine is trying to execute code through unitialized descriptor that points to 0x13ff, which is obviously wrong (and unaligned on word-boundaries for 68k code).	2005-07-02 17:51:43 +00:00
gbeauche	2881c20813	Hopefully fix the remaining issue in the High Resolution Timing support ... code and re-enable it on Linux platforms (they have clock_nanosleep). Why did I trigger an interrupt inside a held lock? Hmmm, we should probably add an _ack semaphore like we do e.g. for ethernet.	2005-07-01 23:15:11 +00:00
gbeauche	245c691102	Check for <stdint.h> ourselves + build with -mdynamic-no-pic on MacOS X.	2005-07-01 06:16:00 +00:00

gbeauche	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.	2005-06-30 22:19:01 +00:00
gbeauche	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.	2005-06-30 15:29:11 +00:00
gbeauche	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.	2005-06-30 13:29:43 +00:00
gbeauche	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.	2005-06-30 10:17:58 +00:00
gbeauche	c9b044aeaf	Completely avoid any form of nested interrupt processing.	2005-06-30 09:09:59 +00:00
gbeauche	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.	2005-06-30 07:34:17 +00:00
gbeauche	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.	2005-06-30 06:38:09 +00:00
gbeauche	7ac6ad2f46	Clean-ups: comments, ticks per sec output, don't restore r13 twice.	2005-06-28 16:50:30 +00:00
gbeauche	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.	2005-06-28 16:47:32 +00:00
gbeauche	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.	2005-06-25 11:40:29 +00:00
gbeauche	198925c5ae	clean-ups from previous experiment with sched_yield(), this one caused a ... slow-down too.	2005-06-25 11:36:35 +00:00
gbeauche	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.	2005-06-25 11:06:24 +00:00
gbeauche	b92ce82a32	Rewrite SheepThreads locks & semaphores. They now look much better and avoid ... busy waits for acquiring spin locks.	2005-06-25 11:00:30 +00:00

gbeauche	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.	2005-06-23 16:23:31 +00:00

gbeauche	c33f09b2d8	Fix crash in FBDev DGA mode when it failed to initialize (here, that was ... because fb visual was Direct Color instead of True Color). We used to initialize the_buffer* even if !open_display. Report that gracefully with the dedicated STR_OPEN_WINDOW_ERR.	2005-06-22 16:40:24 +00:00

gbeauche	f226f793dd	Extend internal math library from GNU libc to accomodate older systems ... with glibc 2.2.X or simply no C99 capable C library. Fix vrfiz instruction to really truncate on float values.	2005-06-22 12:32:32 +00:00
gbeauche	28a167b3bd	Avoid <limits> to determine vector register numeric_limits<>. This fixes ... build with ancient compilers like gcc "2.96".	2005-06-22 12:27:01 +00:00
gbeauche	3aa78832fc	pointer-to-member-functions fixlets, NULL may be (void *)0 on ancient ... compilers which is not suitable here.	2005-06-22 12:25:43 +00:00

gbeauche	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.	2005-03-28 09:05:28 +00:00
gbeauche	5810c6a764	Use "screen TYPE/WIDTH/HEIGHT" prefs item by default on Unix systems. The ... former options (windowmodes/screenmodes) are migrated if the user uses the GUI. Also make a note about EXPERIMENTAL state for jit68k.	2005-03-27 22:32:46 +00:00
gbeauche	abd2c5406f	Add "screen" prefs item similar to Basilisk II. Don't ignore SEGV by default ... as this could hide real bugs.	2005-03-27 22:08:33 +00:00
gbeauche	08e30a894e	disable 68k DR emulator for now (not stable enough yet)	2005-03-27 22:06:52 +00:00
gbeauche	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)	2005-03-27 19:05:18 +00:00
gbeauche	0bc6418ea6	Implement screen win/WIDTH/HEIGHT prefs item that overrides any other value ... for windowmodes and screenmodes. Necessary for arbitrary full screen mode sizes.	2005-03-27 14:53:04 +00:00
gbeauche	fbe378f780	Add custom video modes for full screen in unsual resolutions (e.g. 1400x1050). ... X11 and SDL infrastructures have yet to be implemented	2005-03-27 13:44:45 +00:00
gbeauche	ca7a87465b	Disable high-res timings as it could still hang. The advantage is that we ... now can use special mutexes to debug deadlocks	2005-03-27 13:41:46 +00:00

gbeauche	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.	2005-03-20 23:07:11 +00:00

gbeauche	dd7b09ebe8	Use a mutex to protect wakeup_time instead of a semaphore, do we want some ... sort of barrier synchronisation? Anyhow, the current implementation looks reasonable enough now when using old LinuxThreads without TLS. XXX: in the past, the sem_post in sigsuspend_handler would not release the calling thread thus entering into a mutual waiting condition.	2005-03-16 00:35:51 +00:00

gbeauche	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 (PowerOpen/AIX ABI)	2005-02-27 21:52:06 +00:00

gbeauche	73d51962f6	Merge in-progress PowerPC "JIT1" engine for AMD64, IA-32, PPC. ... The merge probably got wrong as there are some problems probably due to the experiment begining with CR deferred evaluation. With nbench/ppc, performance improvement was around 2x.

gbeauche	cd86ff9e94	- Start emulating the FPSCR. Fix mtfsf, mffs. ... - Implement mftbr so that MacOS can fully boot with extensions. However, using clock() is probably not the right solution. Patching UpTime from DriverServicesLib et al. may be a better solution.	2003-11-09 15:39:30 +00:00
