194 /* NOTE: Interrupts might get called from three modes: real mode, 16-bit, and
195 * (via DeviceIoControl) 32-bit. For automatic conversion of pointer
196 * parameters, interrupt handlers should use CTX_SEG_OFF_TO_LIN with
197 * the contents of a segement register as second and the contents of
198 * a *32-bit* general register as third parameter, e.g.
199 * CTX_SEG_OFF_TO_LIN( context, DS_reg(context), EDX_reg(context) )
200 * This will generate a linear pointer in all three cases:
201 * Real-Mode: Seg*16 + LOWORD(Offset) + V86BASE
202 * 16-bit: convert (Seg, LOWORD(Offset)) to linear
203 * 32-bit: use Offset as linear address (DeviceIoControl!)
205 * Real-mode is recognized by checking the V86 bit in the flags register,
206 * 32-bit mode is recognized by checking whether 'seg' is a system selector
207 * (0 counts also as 32-bit segment).
