 191  * Solaris is somewhat picky about how many heads and sectors per track you

 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.
