237  * Solaris is somewhat picky about how many heads and sectors per track you
238  * have defined in mode pages 3 and 4.  These values seem to cause Solaris
239  * to get the capacity more or less right when you run the format tool.
240  * They still have problems when dealing with devices larger than 1TB,
241  * but there isn't anything we can do about that.
242  *
243  * For smaller LUN sizes, this ends up causing the number of cylinders to
244  * work out to 0.  Solaris actually recognizes that and comes up with its
245  * own bogus geometry to fit the actual capacity of the drive.  They really
246  * should just give up on geometry and stick to the read capacity
247  * information alone for modern disk drives.
248  *
249  * One thing worth mentioning about Solaris' mkfs command is that it
250  * doesn't like sectors per track values larger than 256.  512 seems to
251  * work okay for format, but causes problems when you try to make a
252  * filesystem.
253  *
254  * Another caveat about these values:  the product of these two values
255  * really should be a power of 2.  This is because of the simplistic
256  * shift-based calculation that we have to use on the i386 platform to
257  * calculate the number of cylinders here.  (If you use a divide, you end
258  * up calling __udivdi3(), which is a hardware FP call on the PC.  On the
259  * XScale, it is done in software, so you can do that from inside the
260  * kernel.)
261  *
262  * So for the current values (256 S/T, 128 H), we get 32768, which works
263  * very nicely for calculating cylinders.
264  *
265  * If you want to change these values so that their product is no longer a
266  * power of 2, re-visit the calculation in ctl_init_page_index().  You may
267  * need to make it a bit more complicated to get the number of cylinders
268  * right.
