32bit RGB modes should work directly and get a nice speed increase. Can't remember if it was ARGB or RGBA, but one of them certainly works with direct video output.

All I know is that this two functions fail to give me correct colors bitmap format.
the memory address returned from p96GetBitMapAttr(the_bitmap, P96BMA_MEMORY)
is in a corrupt gfx card format (32bit) GBAR.


static bool get_direct_video_from_window()
{
the_bitmap = the_win -> RPort -> BitMap;

VideoMonitor.mac_frame_base = (uint32)Host2MacAddr((uint8 *) p96GetBitMapAttr(the_bitmap, P96BMA_MEMORY));
VideoMonitor.bytes_per_row = p96GetBitMapAttr(the_bitmap, P96BMA_BYTESPERROW);
}



static bool get_direct_video_from_screen()
{
the_bitmap = the_screen->RastPort.BitMap;

VideoMonitor.mac_frame_base = (uint32)Host2MacAddr((uint8 *) p96GetBitMapAttr(the_bitmap, P96BMA_MEMORY));
VideoMonitor.bytes_per_row = p96GetBitMapAttr(the_bitmap, P96BMA_BYTESPERROW);
}


If I use P96LockBitmap() then "rinf.Memory" will be correct ARGB format, problem is I can only access this memory temporary, so its no good for MacOS that can access the memory at any time.


if (lock = p96LockBitMap( the_screen->RastPort.BitMap, (UBYTE *)&rinf, (ULONG)sizeof( struct RenderInfo))
{
// do some thing whit in rinf.Memory...
p96UnlockBitMap( the_screen->RastPort.BitMap, lock );
}

Then I'll list it in the news item.

I'd agree with you, but then we'd both be wrong.

@Moxee

It's on OS4Depot .

"There are 10 types of people in the world: those who understand binary, and those who don't."

I have found this chunk of code and can't remember if it was a working one but take a look... I didn't add byteswapping code and I had 32bit screenmodes working on uA1-Radeon. This code fragment belongs to the time I started to add byteswapping for certain screenmodes (but didn't finish it)

// Open Picasso96 screen
static bool init_screen_p96(ULONG mode_id)
{
// Set relative mouse mode
ADBSetRelMouseMode(true);

// Check if the mode is one we can handle
uint32 depth = p96GetModeIDAttr(mode_id, P96IDA_DEPTH);
uint32 format = p96GetModeIDAttr(mode_id, P96IDA_RGBFORMAT);

switch (depth) {
case 8:
VideoMonitor.mode = VMODE_8BIT;
break;
case 15:
case 16:
if (format != RGBFB_R5G5B5) {
ErrorAlert(GetString(STR_WRONG_SCREEN_FORMAT_ERR));
return false;
}
VideoMonitor.mode = VMODE_16BIT;
break;
case 24:
case 32:
if (format != RGBFB_A8R8G8B8) {
ErrorAlert(GetString(STR_WRONG_SCREEN_FORMAT_ERR));
return false;
}
VideoMonitor.mode = VMODE_32BIT;
break;
default:
ErrorAlert(GetString(STR_WRONG_SCREEN_DEPTH_ERR));
return false;
}

// Yes, get width and height
uint32 width = p96GetModeIDAttr(mode_id, P96IDA_WIDTH);
uint32 height = p96GetModeIDAttr(mode_id, P96IDA_HEIGHT);

VideoMonitor.x = width;
VideoMonitor.y = height;

// Open screen
the_screen = IP96->p96OpenScreenTags(
P96SA_DisplayID, mode_id,
P96SA_Title, (ULONG)GetString(STR_WINDOW_TITLE),
P96SA_Quiet, TRUE,
P96SA_NoMemory, TRUE,
P96SA_NoSprite, TRUE,
P96SA_Exclusive, TRUE,
TAG_END
);
if (the_screen == NULL) {
ErrorAlert(GetString(STR_OPEN_SCREEN_ERR));
return false;
}

// Open window
the_win = IIntuition->OpenWindowTags(NULL,
WA_Left, 0, WA_Top, 0,
WA_Width, width, WA_Height, height,
WA_NoCareRefresh, TRUE,
WA_Borderless, TRUE,
WA_Activate, TRUE,
WA_RMBTrap, TRUE,
WA_ReportMouse, TRUE,
WA_CustomScreen, (ULONG)the_screen,
TAG_END
);
if (the_win == NULL) {
ErrorAlert(GetString(STR_OPEN_WINDOW_ERR));
return false;
}

// Set VideoMonitor
ScreenToFront(the_screen);
//USE THIS IF P96 STUFF ISN'T SHOWN CORRECTLY
//#if 1
// VideoMonitor.mac_frame_base = (uint32)Host2MacAddr((uint8 *)VideoMonitor.mac_frame_base);
//#endif

VideoMonitor.mac_frame_base = p96GetBitMapAttr(the_screen->RastPort.BitMap, P96BMA_MEMORY);
VideoMonitor.bytes_per_row = p96GetBitMapAttr(the_screen->RastPort.BitMap, P96BMA_BYTESPERROW);
return true;
}

Sorry that code is totally useless can can't possibly work, for one thing the
VideoMonitor.mac_frame_base is not converted to MacOS address space.

the line that does convert memory in to MacOS address space is two line up, and disabled.

// VideoMonitor.mac_frame_base = (uint32)Host2MacAddr((uint8 *)VideoMonitor.mac_frame_base);

and as I wrote p96GetBitMapAttr(the_screen->RastPort.BitMap, P96BMA_MEMORY);

Returns the Memory in wrong byte format.

If was possible to set VideoMonitor.mode to GBAR then direct video might work.

Well, I had a working version of Basilisk II for OS4 some years ago and it still works on OS4 final with latest updates, if you want to take a look I could send the full sources to to your email, c&p to web forums isn't exacty comfortable...

Moreover, I could send you a working binary with direct video working as a proof if you want.

I had a question for the guru's working on this project. I'd like to use a hard partition for the mac boot. This new version see's the partition just fine and reports the size correctly. When I tell the Mac to initialize it I get an error "Disk initialization failed!". I suspect I need set the Partition type correctly, it's currently SFS. I looked for some guidance on the partition type with no luck. Any thoughts?

Thanks,
