These values seem to cause Solaris 226 * to get the capacity more or less right when you run the format tool. 227 * They still have problems when dealing with devices larger than 1TB, 228 * but there isn't anything we can do about that. 229 * 230 * For smaller LUN sizes, this ends up causing the number of cylinders to 231 * work out to 0. Solaris actually recognizes that and comes up with its 232 * own bogus geometry to fit the actual capacity of the drive. They really 233 * should just give up on geometry and stick to the read capacity 234 * information alone for modern disk drives. 235 * 236 * One thing worth mentioning about Solaris' mkfs command is that it 237 * doesn't like sectors per track values larger than 256. 512 seems to 238 * work okay for format, but causes problems when you try to make a 239 * filesystem. 240 * 241 * Another caveat about these values: the product of these two values 242 * really should be a power of 2. This is because of the simplistic 243 * shift-based calculation that we have to use on the i386 platform to 244 * calculate the number of cylinders here. (If you use a divide, you end 245 * up calling __udivdi3(), which is a hardware FP call on the PC. On the 246 * XScale, it is done in software, so you can do that from inside the 247 * kernel.) 248 * 249 * So for the current values (256 S/T, 128 H), we get 32768, which works 250 * very nicely for calculating cylinders. 251 * 252 * If you want to change these values so that their product is no longer a 253 * power of 2, re-visit the calculation in ctl_init_page_index(). You may 254 * need to make it a bit more complicated to get the number of cylinders 255 * right. 256 */ 257#define CTL_DEFAULT_SECTORS_PER_TRACK 256 258#define CTL_DEFAULT_HEADS 128 259 260#define CTL_DEFAULT_ROTATION_RATE SVPD_NON_ROTATING 261 262struct ctl_page_index;
