192 * Solaris is somewhat picky about how many heads and sectors per track you
193 * have defined in mode pages 3 and 4.  These values seem to cause Solaris
194 * to get the capacity more or less right when you run the format tool.
195 * They still have problems when dealing with devices larger than 1TB,
196 * but there isn't anything we can do about that.
197 *
198 * For smaller LUN sizes, this ends up causing the number of cylinders to
199 * work out to 0.  Solaris actually recognizes that and comes up with its
200 * own bogus geometry to fit the actual capacity of the drive.  They really
201 * should just give up on geometry and stick to the read capacity
202 * information alone for modern disk drives.
203 *
204 * One thing worth mentioning about Solaris' mkfs command is that it
205 * doesn't like sectors per track values larger than 256.  512 seems to
206 * work okay for format, but causes problems when you try to make a
207 * filesystem.
208 *
209 * Another caveat about these values:  the product of these two values
210 * really should be a power of 2.  This is because of the simplistic
211 * shift-based calculation that we have to use on the i386 platform to
212 * calculate the number of cylinders here.  (If you use a divide, you end
213 * up calling __udivdi3(), which is a hardware FP call on the PC.  On the
214 * XScale, it is done in software, so you can do that from inside the
215 * kernel.)
216 *
217 * So for the current values (256 S/T, 128 H), we get 32768, which works
218 * very nicely for calculating cylinders.
219 *
220 * If you want to change these values so that their product is no longer a
221 * power of 2, re-visit the calculation in ctl_init_page_index().  You may
222 * need to make it a bit more complicated to get the number of cylinders
223 * right.
