[SDL] [PATCH] fix FB_VideoQuit for ia64
Jesse Barnes
Fri Jan 14 11:13:54 PST 2005

I noticed that on my ia64 machine when SDL_Quit was called, the machine would
hang in weird ways. It turned out to be caused by a machine check in the
memset() call near the top of FB_VideoQuit. Generally memset shouldn't be
used on I/O regions like the framebuffer or other I/O device memory (the
Linux kernel has special routines for dealing with I/O memory), so I changed
the #ifdef __powerpc__ to #if defined(__powerpc__) || defined(__ia64__) and
SDL_Quit now works properly. The change should probably be made
unconditional though since doing one byte at a time is the only way to be
portable, afaik.

     3 Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC
     4 ==============================================================================
     5 
     6 These instructions are for people using the Apple MPW environment:
     7 http://developer.apple.com/tools/mpw-tools/
     8 
     9 CodeWarrior projects are available in the CWprojects directory.
    10 
    11 ==============================================================================
    12 I.  Building the Simple DirectMedia Layer libraries:
    13     (This step isn't necessary if you have the SDL binary distribution)
    14 
    15   First, unpack the MPWmake.sea.hqx archive and move SDL.make into the
    16   SDL directory.
    17 
    18   Start MPW
    19 
    20   Set the current directory within MPW to the SDL toplevel directory.
    21 
    22   Build "SDL"  (Type Command-B and enter "SDL" in the dialog)
    23 
    24   If everything compiles successfully, you now have the PPC libraries
    25   "SDL" and "SDLmain.o" in the 'lib' subdirectory.
    26 
    27 ==============================================================================
    28 II. Building the Simple DirectMedia Layer test programs:
    29 
    30   First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to
    31   the main SDL directory, and move the makefiles in the new test subdirectory
    32   to the SDL 'test' subdirectory.
    33 
    34   Start MPW
    35 
    36   Set the current directory within MPW to the SDL 'test' subdirectory.
    37 
    38   Build the programs that have an associated MPW makefile (file ending
    39   with .make), including "testwin", "testalpha", and "graywin".
    40 
    41   Copy the SDL library file into the test directory, and run!
    42 
    43 ==============================================================================
    44 III. Building the Simple DirectMedia Layer demo programs:
    45 
    46   Copy one of the test program Makefiles to the demo directory
    47   and modify it to match the sources in the demo.
    48 
    49 ==============================================================================
    50 IV.  Enjoy! :)

    52   If you have a project you'd like me to know about, or want to ask questions,
    53   go ahead and join the SDL developer's mailing list by sending e-mail to:
    54 
    55 	sdl-request@libsdl.org
    56 
    57   and put "subscribe" into the subject of the message. Or alternatively you
    58   can use the web interface:
