SDL-1.2.7 patches for A1200

[epinter]

I made these patches to run SDL-1.2.7 on A1200 (using qt/e). I can see the image and hear the sound, but I can't rotate the screen.
Somebody can help ?

I have SDL-1.2.12 library using fbcon video driver. Tested and working on E680i and A1200 (at least it works for rockbox, support 16bpp only) but have no rotation code also. My solution, added rotation code inside rockbox. Is it bad? No, its make rockbox much faster compare to qtopia video driver on E680i. Of course make SDL game port to A1200 more complicated.

can you send me or post the patches ?

Sorry, far away from my code right now and still need some work on event catcher. Have no full 18bpp support also. My event catcher via a socket (taken from chyp's opieproxy idea) sometimes stop working on A1200 (button/touchscreen stop responding sometimes).

Some tips if you have a plan to compile SDL fbcon:
1. Comment out open mouse and open keyboard command
2. Comment out enter graphic console command
3. Comment out save and restore graphic palette command
4. Comment out FBIO_PUTSCREENINFO command
5. Write your own socket client to catch opieproxy event

Rockbox release delayed because above event catcher problem

Thank you for the tips. I discovered the FBIOPUT_VSCREENINFO because of SDL freezes. A1200 doesn't like FBIOPUT.

If I find something about SDL rotation, I will tell you.

Decided to made a new video driver for EZX device base on fbcon and qtopia video driver. Known working for Rockbox port on E680i and A1200. Download SDL-1.2.12, and then apply my patch. Please read README.EZX inside SDL-1.2.12 folder. Edit my setenv.sh script if needed and then run:

# source setenv.sh
# CFLAGS="-Os -mcpu=xscale -mtune=xscale -fsigned-char -Wa,-mcpu=iwmmxt -fno-guess-branch-probability -fno-if-conversion -fno-delayed-branch -fno-loop-optimize -fcrossjumping -foptimize-sibling-calls -fgcse -fexpensive-optimizations -fstrength-reduce -frerun-loop-opt -fforce-mem -fpeephole2 -fschedule-insns -fschedule-insns2 -fstrict-aliasing -freorder-functions -fsched-interblock -fno-align-jumps -fno-align-labels -fno-align-functions -finline-functions -frename-registers -fno-math-errno -funsafe-math-optimizations -fno-trapping-math -ffinite-math-only -finline-limit=500 -fno-builtin -fno-rtti" ./configure --host=arm-linux-gnu --disable-debug --enable-cdrom --enable-threads --enable-timers --enable-endian --enable-file --enable-oss --disable-alsa --disable-esd --disable-arts --disable-diskaudio --disable-nas --disable-esd-shared --disable-esdtest --disable-mintaudio --disable-nasm --disable-video-x11 --disable-video-dga --disable-video-fbcon --disable-video-directfb --disable-video-ps2gs --disable-video-xbios --disable-video-gem --disable-video-dummy --disable-video-opengl --enable-input-events --enable-pthreads--disable-video-picogui --disable-video-qtopia --enable-video-ezx --enable-dlopen --prefix=/opt/a1200-lib

Thank you very much for the patch. I will try it.
I just ported your eClock 0.2 to A1200... I posted the patch on the same thread...
