Hi all,
we’re migrating a SDL1 application to SDL2 which should run on two different x86 devices with Yocto and GBM/KMSDRM.
The first one which runs without problem is a Intel Tiger Lake-based device with Iris driver. The second one is older, a Intel Haswell-based device with i965 driver. This is the problematic one.
Our application is writing to a directly to a surface/backbuffer and then flips it to be visible. We need to use the Software renderer for that. The behavior with that should be the same as with SDL1 and X11 graphics stack.
We’re using kernel 5.4, amd64, SDL 2.0.20 and Mesa 21.3.5.
Here’s the problem:
When calling SDL_RenderPresent the application crashes on the i965-based device with the message
i965: Failed to submit batchbuffer: Invalid argument
while it’s running without problem on the Iris-based device.
I’m able to reproduce it with this simple test program:
#include <SDL2/SDL.h>
#include <iostream>
#include <vector>
int main( int argc, char** argv )
{
SDL_Init( 0 );
// SDL_LogSetAllPriority(SDL_LOG_PRIORITY_VERBOSE);
std::cout << "Testing video drivers..." << '\n';
std::vector< bool > drivers( SDL_GetNumVideoDrivers() );
for( int i = 0; i < drivers.size(); ++i )
{
drivers[ i ] = ( 0 == SDL_VideoInit( SDL_GetVideoDriver( i ) ) );
SDL_VideoQuit();
}
std::cout << "SDL_VIDEODRIVER available:";
for( int i = 0; i < drivers.size(); ++i )
{
std::cout << " " << SDL_GetVideoDriver( i );
}
std::cout << '\n';
std::cout << "SDL_VIDEODRIVER usable :";
for( int i = 0; i < drivers.size(); ++i )
{
if( !drivers[ i ] ) continue;
std::cout << " " << SDL_GetVideoDriver( i );
}
std::cout << '\n';
if( SDL_Init( SDL_INIT_VIDEO ) < 0 )
{
std::cerr << "SDL_Init(): " << SDL_GetError() << '\n';
return EXIT_FAILURE;
}
std::cout << "SDL_VIDEODRIVER selected : " << SDL_GetCurrentVideoDriver() << '\n';

if( nullptr == screen )
{

return EXIT_FAILURE;
}
Uint32 background_color = ::SDL_MapRGB(screen->format, 255, 255, 255);
Uint32 background_color_overbright = ::SDL_MapRGB(screen->format, 160, 160, 160);
bool running = true;
unsigned char i = 0;
int ret = 0;
while( running )
{
SDL_Event ev;
while( SDL_PollEvent( &ev ) )
{
std::cerr << "SDL_PollEvent(): " << ev.type << '\n';
if( ( ev.type == SDL_QUIT ) ||
( ev.type == SDL_KEYDOWN && ev.key.keysym.sym == SDLK_ESCAPE ) )
{

}
}

if( 0 != ret )
{

{

}
std::cerr << "SDL_RenderPresent(): " << '\n';
SDL_RenderPresent( renderer );
/* std::cerr << "SDL_UpdateWindowSurface(): " << '\n';

}*/
i++;
}
SDL_DestroyRenderer( renderer );
SDL_DestroyWindow( window );
SDL_Quit();
return 0;
}
The output of this program:

Any ideas how to fix this? I’ve already tried SDL_UpdateWindowSurface but it aborts with the same error message.
Thank you in advance!
