- * CONS_IOPERM ioctl() to grant access only to those ports we care about.
- * This way we can guarantee some small level of stability because a driver

- *
- * So, for the time being, we change our IOPL until such time as the XFree86

- * To map the video memory, we first need to see if we are on a multi-console
- * system. If we are, we need to try to use an existing video class in the
- * kernel. We do this by retrieving the list of currently defined classes
- * (via the new CONS_GETCLASS ioctl()) to see if we have a class that will
- * match the range of memory we desire. If we can't find one, we have an
- * error and we abort.
- *
- * If we are not using a multi-console, we can simply use mmap() to map in
- * the frame buffer, using the classs-access method as a fall-back only if
- * the mmap() fails (it shouldn't). We always set the appropriate pointers
- * in the config structure to point ot the right function to map and unmap
- * the video memory. An alternative to using mmap() is to use the new
- * CONS_ADDVAS call, which will use vasmalloc() and vasbind() in the kernel
- * to map the physical address to a virtual one, which it then returns.
- * I am not 100% sure if this is faster or not, but it may prove easier to
- * debug things. Just to be on the safe side, I have included both methods
- * here, and the mmap() method can be used by setting USE_VASMETHOD to 0
- * above.
