225 * Solaris is somewhat picky about how many heads and sectors per track you
226 * have defined in mode pages 3 and 4.  These values seem to cause Solaris
227 * to get the capacity more or less right when you run the format tool.
228 * They still have problems when dealing with devices larger than 1TB,
229 * but there isn't anything we can do about that.
230 *
231 * For smaller LUN sizes, this ends up causing the number of cylinders to
232 * work out to 0.  Solaris actually recognizes that and comes up with its
233 * own bogus geometry to fit the actual capacity of the drive.  They really
234 * should just give up on geometry and stick to the read capacity
235 * information alone for modern disk drives.
236 *
237 * One thing worth mentioning about Solaris' mkfs command is that it
238 * doesn't like sectors per track values larger than 256.  512 seems to
239 * work okay for format, but causes problems when you try to make a
240 * filesystem.
241 *
242 * Another caveat about these values:  the product of these two values
243 * really should be a power of 2.  This is because of the simplistic
244 * shift-based calculation that we have to use on the i386 platform to
245 * calculate the number of cylinders here.  (If you use a divide, you end
246 * up calling __udivdi3(), which is a hardware FP call on the PC.  On the
247 * XScale, it is done in software, so you can do that from inside the
248 * kernel.)
249 *
250 * So for the current values (256 S/T, 128 H), we get 32768, which works
251 * very nicely for calculating cylinders.
252 *
253 * If you want to change these values so that their product is no longer a
254 * power of 2, re-visit the calculation in ctl_init_page_index().  You may
255 * need to make it a bit more complicated to get the number of cylinders
256 * right.
