These values seem to cause Solaris 199 * to get the capacity more or less right when you run the format tool. 200 * They still have problems when dealing with devices larger than 1TB, 201 * but there isn't anything we can do about that. 202 * 203 * For smaller LUN sizes, this ends up causing the number of cylinders to 204 * work out to 0. Solaris actually recognizes that and comes up with its 205 * own bogus geometry to fit the actual capacity of the drive. They really 206 * should just give up on geometry and stick to the read capacity 207 * information alone for modern disk drives. 208 * 209 * One thing worth mentioning about Solaris' mkfs command is that it 210 * doesn't like sectors per track values larger than 256. 512 seems to 211 * work okay for format, but causes problems when you try to make a 212 * filesystem. 213 * 214 * Another caveat about these values: the product of these two values 215 * really should be a power of 2. This is because of the simplistic 216 * shift-based calculation that we have to use on the i386 platform to 217 * calculate the number of cylinders here. (If you use a divide, you end 218 * up calling __udivdi3(), which is a hardware FP call on the PC. On the 219 * XScale, it is done in software, so you can do that from inside the 220 * kernel.) 221 * 222 * So for the current values (256 S/T, 128 H), we get 32768, which works 223 * very nicely for calculating cylinders. 224 * 225 * If you want to change these values so that their product is no longer a 226 * power of 2, re-visit the calculation in ctl_init_page_index(). You may 227 * need to make it a bit more complicated to get the number of cylinders 228 * right. 229 */ 230#define CTL_DEFAULT_SECTORS_PER_TRACK 256 231#define CTL_DEFAULT_HEADS 128 232 233#define CTL_DEFAULT_ROTATION_RATE SVPD_NON_ROTATING 234 235struct ctl_page_index;
