255 * VSID allocation
256 *
257 * We first generate a 36-bit "proto-VSID". For kernel addresses this
258 * is equal to the ESID, for user addresses it is:
259 * (context << 15) | (esid & 0x7fff)
260 *
261 * The two forms are distinguishable because the top bit is 0 for user
262 * addresses, whereas the top two bits are 1 for kernel addresses.
263 * Proto-VSIDs with the top two bits equal to 0b10 are reserved for
264 * now.
265 *
266 * The proto-VSIDs are then scrambled into real VSIDs with the
267 * multiplicative hash:
268 *
269 * VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
270 * where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
271 * VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
272 *
273 * This scramble is only well defined for proto-VSIDs below
274 * 0xFFFFFFFFF, so both proto-VSID and actual VSID 0xFFFFFFFFF are
275 * reserved. VSID_MULTIPLIER is prime, so in particular it is
276 * co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
277 * Because the modulus is 2^n-1 we can compute it efficiently without
278 * a divide or extra multiply (see below).
279 *
280 * This scheme has several advantages over older methods:
281 *
282 * - We have VSIDs allocated for every kernel address
283 * (i.e. everything above 0xC000000000000000), except the very top
284 * segment, which simplifies several things.
285 *
286 * - We allow for 15 significant bits of ESID and 20 bits of
287 * context for user addresses. i.e. 8T (43 bits) of address space for
288 * up to 1M contexts (although the page table structure and context
289 * allocation will need changes to take advantage of this).
290 *
291 * - The scramble function gives robust scattering in the hash
292 * table (at least based on some initial results). The previous
293 * method was more susceptible to pathological cases giving excessive
294 * hash collisions.
295 */

260 * VSID allocation
261 *
262 * We first generate a 36-bit "proto-VSID". For kernel addresses this
263 * is equal to the ESID, for user addresses it is:
264 * (context << 15) | (esid & 0x7fff)
265 *
266 * The two forms are distinguishable because the top bit is 0 for user
267 * addresses, whereas the top two bits are 1 for kernel addresses.
268 * Proto-VSIDs with the top two bits equal to 0b10 are reserved for
269 * now.
270 *
271 * The proto-VSIDs are then scrambled into real VSIDs with the
272 * multiplicative hash:
273 *
274 * VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
275 * where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
276 * VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
277 *
278 * This scramble is only well defined for proto-VSIDs below
279 * 0xFFFFFFFFF, so both proto-VSID and actual VSID 0xFFFFFFFFF are
280 * reserved. VSID_MULTIPLIER is prime, so in particular it is
281 * co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
282 * Because the modulus is 2^n-1 we can compute it efficiently without
283 * a divide or extra multiply (see below).
284 *
285 * This scheme has several advantages over older methods:
286 *
287 * - We have VSIDs allocated for every kernel address
288 * (i.e. everything above 0xC000000000000000), except the very top
289 * segment, which simplifies several things.
290 *
291 * - We allow for 15 significant bits of ESID and 20 bits of
292 * context for user addresses. i.e. 8T (43 bits) of address space for
293 * up to 1M contexts (although the page table structure and context
294 * allocation will need changes to take advantage of this).
295 *
296 * - The scramble function gives robust scattering in the hash
297 * table (at least based on some initial results). The previous
298 * method was more susceptible to pathological cases giving excessive
299 * hash collisions.
300 */
