These values seem to cause Solaris 197 * to get the capacity more or less right when you run the format tool. 198 * They still have problems when dealing with devices larger than 1TB, 199 * but there isn't anything we can do about that. 200 * 201 * For smaller LUN sizes, this ends up causing the number of cylinders to 202 * work out to 0. Solaris actually recognizes that and comes up with its 203 * own bogus geometry to fit the actual capacity of the drive. They really 204 * should just give up on geometry and stick to the read capacity 205 * information alone for modern disk drives. 206 * 207 * One thing worth mentioning about Solaris' mkfs command is that it 208 * doesn't like sectors per track values larger than 256. 512 seems to 209 * work okay for format, but causes problems when you try to make a 210 * filesystem. 211 * 212 * Another caveat about these values: the product of these two values 213 * really should be a power of 2. This is because of the simplistic 214 * shift-based calculation that we have to use on the i386 platform to 215 * calculate the number of cylinders here. (If you use a divide, you end 216 * up calling __udivdi3(), which is a hardware FP call on the PC. On the 217 * XScale, it is done in software, so you can do that from inside the 218 * kernel.) 219 * 220 * So for the current values (256 S/T, 128 H), we get 32768, which works 221 * very nicely for calculating cylinders. 222 * 223 * If you want to change these values so that their product is no longer a 224 * power of 2, re-visit the calculation in ctl_init_page_index(). You may 225 * need to make it a bit more complicated to get the number of cylinders 226 * right. 227 */ 228#define CTL_DEFAULT_SECTORS_PER_TRACK 256 229#define CTL_DEFAULT_HEADS 128 230 231#define CTL_DEFAULT_ROTATION_RATE SVPD_NON_ROTATING 232 233struct ctl_page_index;
