These values seem to cause Solaris 240 * to get the capacity more or less right when you run the format tool. 241 * They still have problems when dealing with devices larger than 1TB, 242 * but there isn't anything we can do about that. 243 * 244 * For smaller LUN sizes, this ends up causing the number of cylinders to 245 * work out to 0. Solaris actually recognizes that and comes up with its 246 * own bogus geometry to fit the actual capacity of the drive. They really 247 * should just give up on geometry and stick to the read capacity 248 * information alone for modern disk drives. 249 * 250 * One thing worth mentioning about Solaris' mkfs command is that it 251 * doesn't like sectors per track values larger than 256. 512 seems to 252 * work okay for format, but causes problems when you try to make a 253 * filesystem. 254 * 255 * Another caveat about these values: the product of these two values 256 * really should be a power of 2. This is because of the simplistic 257 * shift-based calculation that we have to use on the i386 platform to 258 * calculate the number of cylinders here. (If you use a divide, you end 259 * up calling __udivdi3(), which is a hardware FP call on the PC. On the 260 * XScale, it is done in software, so you can do that from inside the 261 * kernel.) 262 * 263 * So for the current values (256 S/T, 128 H), we get 32768, which works 264 * very nicely for calculating cylinders. 265 * 266 * If you want to change these values so that their product is no longer a 267 * power of 2, re-visit the calculation in ctl_init_page_index(). You may 268 * need to make it a bit more complicated to get the number of cylinders 269 * right. 270 */ 271#define CTL_DEFAULT_SECTORS_PER_TRACK 256 272#define CTL_DEFAULT_HEADS 128 273 274#define CTL_DEFAULT_ROTATION_RATE SVPD_NON_ROTATING 275 276struct ctl_page_index;
