These values seem to cause Solaris 219 * to get the capacity more or less right when you run the format tool. 220 * They still have problems when dealing with devices larger than 1TB, 221 * but there isn't anything we can do about that. 222 * 223 * For smaller LUN sizes, this ends up causing the number of cylinders to 224 * work out to 0. Solaris actually recognizes that and comes up with its 225 * own bogus geometry to fit the actual capacity of the drive. They really 226 * should just give up on geometry and stick to the read capacity 227 * information alone for modern disk drives. 228 * 229 * One thing worth mentioning about Solaris' mkfs command is that it 230 * doesn't like sectors per track values larger than 256. 512 seems to 231 * work okay for format, but causes problems when you try to make a 232 * filesystem. 233 * 234 * Another caveat about these values: the product of these two values 235 * really should be a power of 2. This is because of the simplistic 236 * shift-based calculation that we have to use on the i386 platform to 237 * calculate the number of cylinders here. (If you use a divide, you end 238 * up calling __udivdi3(), which is a hardware FP call on the PC. On the 239 * XScale, it is done in software, so you can do that from inside the 240 * kernel.) 241 * 242 * So for the current values (256 S/T, 128 H), we get 32768, which works 243 * very nicely for calculating cylinders. 244 * 245 * If you want to change these values so that their product is no longer a 246 * power of 2, re-visit the calculation in ctl_init_page_index(). You may 247 * need to make it a bit more complicated to get the number of cylinders 248 * right. 249 */ 250#define CTL_DEFAULT_SECTORS_PER_TRACK 256 251#define CTL_DEFAULT_HEADS 128 252 253#define CTL_DEFAULT_ROTATION_RATE SVPD_NON_ROTATING 254 255struct ctl_page_index;
