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