I am not replacing the following header files used by the Windows build, as I don't have a Windows build setup to test. Please point the Windows build at the header files inside these clean distribution packages and garbage collect the duplicates: GLew/*.h and SDL/Include_1.2. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5711 8ced0084-cf51-0410-be5f-012b33b47a6e

Patch version 0.9 of SDL(Simple DirectMedia Layer) for Nano-X API
|
|
=================================================================

|
|
|
This patch is against SDL version 1.2.4.
|
|
It enhances previous patch 0.8 by providing direct framebuffer
|
|
access as well as dynamic hardware pixel type support, not
|
|
requiring a compile-time option setting for different framebuffer
|
|
modes.
|
|
Tested against Microwindows version 0.89pre9.
|
|
|
|
Older Microwindows versions
|
|
===========================
|
|
If running on a version older than Microwindows 0.89pre9,
|
|
the following items might need to be patched in Microwindows.
|
|
|
|
1. Patch src/nanox/client.c::GrClose()
|
|
It fixes the client side GrClose(). In the original version,
|
|
GrOpen() can only be called once. When the GrOpen() is called at
|
|
the second time, the program will terminate. In order to prevent
|
|
this situation, we need to insert "nxSocket = -1" after
|
|
"close(nxSocket)" in GrClose(). If you do not have this problem,
|
|
you may skip this step.
|
|
|
|
2. Patch src/nanox/clientfb.c to return absolute x,y coordinates
|
|
when using GrGetWindowFBInfo(). Copy the version 0.89pre9
|
|
of src/nanox/clientfb.c to your system, or configure
|
|
using --disable-nanox-direct-fb.
|
|
|
|
=============
|
|
Quick Install
|
|
=============
|
|
|
|
1. ./configure --disable-video-x11 --disable-video-fbcon \
|
|
--enable-video-nanox \
|
|
--with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal]
|
|
2. make clean
|
|
3. make
|
|
4. make install (as root)
|
|
|
|
============
|
|
Nitty-gritty
|
|
============
|
|
|
|
--enable-nanox-direct-fb Use direct framebuffer access
|
|
--enable-nanox-debug Show debug messages
|
|
--enable-nanox-share-memory Use shared-memory to speed up
|
|
|
|
When running multi-threaded applications using SDL, such
|
|
as SMPEG, set THREADSAFE=Y in Microwindows' config file,
|
|
to enable GrXXX() system call critical section support.
|
|
|
|

|
|
Some programs can be used to test this patch.

Todo List
|
|
=========
|
|
|
|
1. Create hardware surface
|
|
2. Create YUVOverlay on hardware
|
|
3. Use OpenGL
|
|
4. Gamma correction
|
|
5. Hide/Change mouse pointer
|
|
6. Better window movement control with direct fb access
|
|
7. Palette handling in 8bpp could be improved
|
