These values seem to cause Solaris 187 * to get the capacity more or less right when you run the format tool. 188 * They still have problems when dealing with devices larger than 1TB, 189 * but there isn't anything we can do about that. 190 * 191 * For smaller LUN sizes, this ends up causing the number of cylinders to 192 * work out to 0. Solaris actually recognizes that and comes up with its 193 * own bogus geometry to fit the actual capacity of the drive. They really 194 * should just give up on geometry and stick to the read capacity 195 * information alone for modern disk drives. 196 * 197 * One thing worth mentioning about Solaris' mkfs command is that it 198 * doesn't like sectors per track values larger than 256. 512 seems to 199 * work okay for format, but causes problems when you try to make a 200 * filesystem. 201 * 202 * Another caveat about these values: the product of these two values 203 * really should be a power of 2. This is because of the simplistic 204 * shift-based calculation that we have to use on the i386 platform to 205 * calculate the number of cylinders here. (If you use a divide, you end 206 * up calling __udivdi3(), which is a hardware FP call on the PC. On the 207 * XScale, it is done in software, so you can do that from inside the 208 * kernel.) 209 * 210 * So for the current values (256 S/T, 128 H), we get 32768, which works 211 * very nicely for calculating cylinders. 212 * 213 * If you want to change these values so that their product is no longer a 214 * power of 2, re-visit the calculation in ctl_init_page_index(). You may 215 * need to make it a bit more complicated to get the number of cylinders 216 * right. 217 */ 218#define CTL_DEFAULT_SECTORS_PER_TRACK 256 219#define CTL_DEFAULT_HEADS 128 220 221#define CTL_DEFAULT_ROTATION_RATE SVPD_NON_ROTATING 222 223struct ctl_page_index;
