Attached is a patch to SheepShaver, to fix a problem where the ROM file can only be found on the first boot.

When a user creates a new SheepShaver machine, there is no preference file, so there is not ROM path preference. SheepShaver has logic so that in this case, it will look for a ROM file named "ROM" or "Mac OS ROM" in the current directory.

The user starts SheepShaver in order to get to the built-in Preferences Editor, and changes various settings (such as creation of a hard disk). Then the user reboots.

If the user forgot to set the ROM path at this time, then SheepShaver can no longer boot. The only recourse is for the user to find and delete the preferences file, or use an external preferences editor to set the ROM path.

The fix is to change SheepShaver to use the default ROM names when either the rom path is null (no preference) OR an empty string (preference exists with no rom path).

Attached is a patch to SheepShaver, to fix a SIGSEGV crash that occurs when booting a new machine with OS 7.5.

One of the bytes in the xPRAM portion of the NVRAM controls which version of the system memory manager is used by OS 7.5: the legacy 680x0 memory manager or the PPC memory manager (aka the "Modern Memory Manager"). OS 7.5 is supposed to be able to use either one, but for some reason SheepShaver crashes on boot if the 680x0 version is used.

Later Mac OS versions don't have this problem. They don't support the 680x0 version, so they force the PPC version to be used.

The fix is to have SheepShaver initialize the NVRAM to use the PPC memory manager. Note: This is supposed to be the default in OS 7.5.

This affects when a new NVRAM file is used, or when it is initialized after doing zapping the PRAM.

Attached is a patch to SheepShaver to fix memory allocation problems when OS X 10.5 is the host. It also relaxes the 512 MB RAM limit on OS X hosts.


Problem
-------
Some users have been unable to run SheepShaver on OS X 10.5 (Leopard) hosts. The symptom is error "ERROR: Cannot map RAM: File already exists".

SheepShaver allocates RAM at fixed addresses. If it is running in "Real" addressing mode, and can't allocate at address 0, then it was hard-coded to allocate the RAM area at 0x20000000. The ROM area as allocated at 0x40800000.

The normal configuration is for SheepShaver to run under SDL, which is a Cocoa wrapper. By the time SheepShaver does its memory allocations, the Cocoa application has already started. The result is the SheepShaver memory address space already contains libraries, fonts, Input Managers, and IOKit areas.

On Leopard hosts these areas can land on the same addresses SheepShaver needs, so SheepShaver's memory allocation fails.


Solution
--------
The approach is to change SheepShaver (on Unix & OS X hosts) to allocate the RAM area anywhere it can find the space, rather than at a fixed address.

This could result in the RAM allocated higher than the ROM area, which causes a crash. To prevent this from occurring, the RAM and ROM areas are allocated contiguously.

Previously the ROM starting address was a constant ROM_BASE, which was used throughout the source files. The ROM start address is now a variable ROMBase. ROMBase is allocated and set by main_*.cpp just like RAMBase.

A side-effect of this change is that it lifts the 512 MB RAM limit for OS X hosts. The limit was because the fixed RAM and ROM addresses were such that the RAM could only be 512 MB before it overlapped the ROM area.


Impact
------
The change to make ROMBase a variable is throughout all hosts & addressing modes.

The RAM and ROM areas will only shift when run on Unix & OS X hosts, otherwise the same fixed allocation address is used as before.

This change is limited to "Real" addressing mode. Unlike Basilisk II, SheepShaver *pre-calculates* the offset for "Direct" addressing mode; the offset is compiled into the program. If the RAM address were allowed to shift, it could result in the RAM area wrapping around address 0.


Changes to main_unix.cpp
------------------------
1. Real addressing mode no longer defines a RAM_BASE constant.

2. The base address of the Mac ROM (ROMBase) is defined and exported by this program.

3. Memory management helper vm_mac_acquire is renamed to vm_mac_acquire_fixed. Added a new memory management helper vm_mac_acquire, which allocates memory at any address.

4. Changed and rearranged the allocation of RAM and ROM areas.

Before it worked like this:

  - Allocate ROM area
  - If can, attempt to allocate RAM at address zero
  - If RAM not allocated at 0, allocate at fixed address

We still want to try allocating the RAM at zero, and if using DIRECT addressing we're still going to use the fixed addresses. So we don't know where the ROM should be until after we do the RAM. The new logic is:

  - If can, attempt to allocate RAM at address zero
  - If RAM not allocated at 0
      if REAL addressing
         allocate RAM and ROM together. The ROM address is aligned to a 1 MB boundary
      else (direct addressing)
         allocate RAM at fixed address
  - If ROM hasn't been allocated yet, allocate at fixed address

5. Calculate ROMBase and ROMBaseHost based on where the ROM was loaded.

6. There is a crash if the RAM is allocated too high. To try and catch this, check if it was allocated higher than the kernel data address.

7. Change subsequent code from using constant ROM_BASE to variable ROMBase.


Changes to Other Programs
-------------------------
emul_op.cpp, main.cpp, name_registery.cpp, rom_patches.cpp, rsrc_patches.cpp, emul_ppc.cpp, sheepshaver_glue.cpp, ppc-translate-cpp:
Change from constant ROM_BASE to variable ROMBase.

ppc_asm.S: It was setting register to a hard-coded literal address: 0x40b0d000. Changed to set it to ROMBase + 0x30d000.

ppc_asm.tmpl: It defined a macro ASM_LO16 but it assumed that the macro would always be used with operands that included a register specification. This is not true. Moved the register specification from the macro to the macro invocations.

main_beos.cpp, main_windows.cpp: Since the subprograms are all expecting a variable ROMBase, all the main_*.cpp pgrams have to define and export it. The ROM_BASE constant is moved here for consistency. The mains for beos and windows just allocate the ROM at the same fixed address as before, set ROMBaseHost and ROMBase to that address, and then use ROMBase for the subsequent code.

cpu_emulation.h: removed ROM_BASE constant. This value is moved to the main_*.cpp modules, to be consistent with RAM_BASE.

user_strings_unix.cpp, user_strings_unix.h: Added new error messages related to errors that occur when the RAM and ROM are allocated anywhere.

Attached is a set of patches to port the precise timer that is currently used in the Linux and BeOS builds of SheepShaver to Mac OS X (and any other Mach-based operating systems).

Currently, the Linux build uses the clock_gettime() function to get nanosecond-precision time, and falls back on gettimeofday() if it is not present. Unfortunately, Mac OS X does not currently support clock_gettime(), and gettimeofday() has only microsecond granularity. The Mach kernel, however, has a clock_get_time() function that does very nearly the same thing as clock_gettime(). The patches to BasiliskII cause the timing functions such as timer_current_time() to use clock_get_time() instead of gettimeofday() on Mach-based systems that do not support clock_gettime().

The changes to SheepShaver involve the precise timer. The existing code for Linux uses pthreads and real-time signals to handle the timing. Mac OS X unfortunately does not seem to support real-time signals, so Mach calls are again used to suspend and resume the timer thread in order to attempt to duplicate the Linux and BeOS versions of the timer. The code is somewhat ugly right now, as I decided to leave alone the pre-existing style of the source file, which unfortunately involves #ifdefs scattered throughout the file and some duplication of code. A future patch may want to clean this up to separate out the OS-specific code and put it all together at the top of the file. However, for the time being, this seems to work.

This has not been extensively tested, because I have not been able to get my hands on a good test-case app for the classic Mac OS that would run inside the emulator and try out the timer. However, performance does seem to be better than with the pre-existing code, and nothing seems to have blown up as far as I can tell. I did find a game via a Google search -  Cap'n Magneto - that is known to have problems with Basilisk/SheepShaver's legacy 60 Hz timer, and the opening fade-to-color for this game appears to run much more smoothly with the precise timer code in place.

SheepShaver includes the C errno string in many error messages. One case is when it calls the memory allocation routines in the Basilisk II vm_alloc.cpp program.

This works when the memory allocation routine uses functions that set errno (such as mmap or malloc). For example, running SheepShaver on a Linux hosts produces meaningful error messages.

The problem is that when run on an OS X host, the memory allocation uses Mach routines such as vm_allocate, which do not set errno.

So when SheepShaver reported the error, it used a stale value of errno, which happened to be 17. The result was an extremely misleading error message: "Cannot map RAM: File already exists".

The fix is to change vm_alloc so that it translates Mac return codes into POSIX errno values.

It also initializes errno to 0 at the start of the memory allocation routine, so that no matter what path it takes, it won't return a stale value.
