- * At present, all PowerPC 400-class processors share a similar TLB
- * architecture. The instruction and data sides share a unified,
- * 64-entry, fully-associative TLB which is maintained totally under
- * software control. In addition, the instruction side has a
- * hardware-managed, 4-entry, fully-associative TLB which serves as a
- * first level to the shared TLB. These two TLBs are known as the UTLB
- * and ITLB, respectively (see "mmu.h" for definitions).
- *
- * There are several potential gotchas here. The 40x hardware TLBLO
- * field looks like this:
- *
- * 0 1 2 3 4 ... 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- * RPN..................... 0 0 EX WR ZSEL....... W I M G
- *
- * Where possible we make the Linux PTE bits match up with this
- *
- * - bits 20 and 21 must be cleared, because we use 4k pages (40x can
- * support down to 1k pages), this is done in the TLBMiss exception
- * handler.
- * - We use only zones 0 (for kernel pages) and 1 (for user pages)
- * of the 16 available. Bit 24-26 of the TLB are cleared in the TLB
- * miss handler. Bit 27 is PAGE_USER, thus selecting the correct
- * zone.
- * - PRESENT *must* be in the bottom two bits because swap PTEs
- * use the top 30 bits. Because 40x doesn't support SMP anyway, M is
- * irrelevant so we borrow it for PAGE_PRESENT. Bit 30
- * is cleared in the TLB miss handler before the TLB entry is loaded.
- * - All other bits of the PTE are loaded into TLBLO without
- * modification, leaving us only the bits 20, 21, 24, 25, 26, 30 for
- * software PTE bits. We actually use bits 21, 24, 25, and
- * 30 respectively for the software bits: ACCESSED, DIRTY, RW, and
- * PRESENT.

From: Michael Ellerman @ 2024-06-28 12:12 UTC (permalink / raw)
To: linuxppc-dev
Replace 4xx usage with 44x, and replace 4xx_SOC with 44x.
Also, as pointed out by Christophe, if 44x || BOOKE can be simplified to
just test BOOKE, because 44x always selects BOOKE.
Retain the CONFIG_4xx symbol, as there are drivers that use it to mean
4xx || 44x, those will need updating before CONFIG_4xx can be removed.
