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.
