I don't know why it is that way. I would think it should fail at this point. Anyone know why this is?
Yesterday I noticed on a box at work that if you compile in both vesafb and
atyfb (the box has an ATI 3D RAGE PRO), you get both fb0 (atyfb) and fb1
(vesafb). That's not supposed to happen.
Vesafb did print that the frame buffer was already in use, but it just
continued, cfr. this code:
if (!request_mem_region(vesafb_fix.smem_start, vesafb_fix.smem_len, "vesafb")) {
printk(KERN_WARNING
"vesafb: abort, cannot reserve video memory at 0x%lx\n",
vesafb_fix.smem_start);
/* We cannot make this fatal. Sometimes this comes from magic
spaces our resource handlers simply don't know about */
}
That was on plain 2.6.5. But to my surprise the latest 2.4 behaves the same.
This seems to have been changed in 2.4.15.
Does anyone know why this was changed?
