Hi devels
I'm currently trying to implement a gfxdriver for a custom design based
on an Leon chip on an Altera FPGA. I have managed to mmap the video
hardware I/O registers to the gfxdriver so it is succesfully
initialized, probed and started
I run an example directfb application that does some blits with
alphachannel blend which is the first function i want to accelerate. I
see the enginesync and checkstate functions get called but not the
setstate and blit functions
In checkstate i call
state->accel |= DFXL_BLIT;
and in setstate
state->set |= DFXL_BLIT;
state->mod_hw = 0;
also in blit i just return true
in initdriver is set
funcs->CheckState = sciensis_check_state;
funcs->SetState = sciensis_set_state;
funcs->EngineSync = sciensis_engine_sync;
funcs->Blit = sciensis_blit;
and finally in initdevice
dev_info->caps.flags = CCF_CLIPPING;
dev_info->caps.accel = DFXL_BLIT;
dev_info->caps.blitting = DSBLIT_ALL;
the last just to be sure
after the gfxdriver is initialized and probed i get
(*) DirectFB/Core/WM: Default 0.3 (directfb.org)
(!) DirectFB/DirectFBCreate: Setting desktop resolution to 320x240 failed!
-> Using default resolution.
(!) DirectFB/DirectFBCreate: Setting desktop format failed!
-> Using default format.
(!) DirectFB/DirectFBCreate: Setting desktop buffer mode failed!
-> No virtual resolution support or not enough memory?
Falling back to system back buffer.
that i saw comes from the layers module
i have a framebuffer fixed 320x240x32 @ 0x50000000 (address)
it has allocated 600k of mem
what could be the problem?
thanx in advance guys and girls
