     8   This patch is against SDL version 1.2.4.
     9   It enhances previous patch 0.8 by providing direct framebuffer
    10   access as well as dynamic hardware pixel type support, not
    11   requiring a compile-time option setting for different framebuffer
    12   modes.
    13   Tested against Microwindows version 0.89pre9.
    14 
    15   Older Microwindows versions
    16   ===========================
    17   If running on a version older than Microwindows 0.89pre9,
    18   the following items might need to be patched in Microwindows.
    19 
    20   1. Patch src/nanox/client.c::GrClose()
    21   It fixes the client side GrClose(). In the original version, 
    22   GrOpen() can only be called once. When the GrOpen() is called at 
    23   the second time, the program will terminate. In order to prevent
    24   this situation, we need to insert "nxSocket = -1" after 
    25   "close(nxSocket)" in GrClose(). If you do not have this problem,
    26   you may skip this step. 
    27 
    28   2. Patch src/nanox/clientfb.c to return absolute x,y coordinates
    29   when using GrGetWindowFBInfo().  Copy the version 0.89pre9
    30   of src/nanox/clientfb.c to your system, or configure
    31   using --disable-nanox-direct-fb.
    32 
    33   =============
    34   Quick Install 
    35   =============
    36 
    37   1. ./configure --disable-video-x11 --disable-video-fbcon \ 
    38        --enable-video-nanox \ 
    39        --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] 
    40   2. make clean 
    41   3. make 
    42   4. make install (as root) 
    43 
    44   ============
    45   Nitty-gritty 
    46   ============
    47 
    48   --enable-nanox-direct-fb       Use direct framebuffer access
    49   --enable-nanox-debug           Show debug messages 
    50   --enable-nanox-share-memory    Use shared-memory to speed up 
    51 
    52   When running multi-threaded applications using SDL, such
    53   as SMPEG, set THREADSAFE=Y in Microwindows' config file,
    54   to enable GrXXX() system call critical section support.
    55
