201  * Solaris is somewhat picky about how many heads and sectors per track you
202  * have defined in mode pages 3 and 4.  These values seem to cause Solaris
203  * to get the capacity more or less right when you run the format tool.
204  * They still have problems when dealing with devices larger than 1TB,
205  * but there isn't anything we can do about that.
206  *
207  * For smaller LUN sizes, this ends up causing the number of cylinders to
208  * work out to 0.  Solaris actually recognizes that and comes up with its
209  * own bogus geometry to fit the actual capacity of the drive.  They really
210  * should just give up on geometry and stick to the read capacity
211  * information alone for modern disk drives.
212  *
213  * One thing worth mentioning about Solaris' mkfs command is that it
214  * doesn't like sectors per track values larger than 256.  512 seems to
215  * work okay for format, but causes problems when you try to make a
216  * filesystem.
217  *
218  * Another caveat about these values:  the product of these two values
219  * really should be a power of 2.  This is because of the simplistic
220  * shift-based calculation that we have to use on the i386 platform to
221  * calculate the number of cylinders here.  (If you use a divide, you end
222  * up calling __udivdi3(), which is a hardware FP call on the PC.  On the
223  * XScale, it is done in software, so you can do that from inside the
224  * kernel.)
225  *
226  * So for the current values (256 S/T, 128 H), we get 32768, which works
227  * very nicely for calculating cylinders.
228  *
229  * If you want to change these values so that their product is no longer a
230  * power of 2, re-visit the calculation in ctl_init_page_index().  You may
231  * need to make it a bit more complicated to get the number of cylinders
232  * right.
