- Find out whether you have a PCI motherboard. PCI is the name of a
- bus system, i.e. the way the CPU talks to the other stuff inside
- your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
- VESA. If you have PCI, say Y, otherwise N.
-
- The PCI-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, contains valuable
- information about which PCI hardware does work under Linux and which
- doesn't.

- depends on PCI
- default y
- help
- Enable this option if your platform does not have a CPU cache which
- remains coherent with PCI DMA. It is safest to say 'Y', although you
- will see better performance if you can say 'N', because the PCI DMA
- code will not have to flush the CPU's caches. If you have a PCI host
- bridge integrated with your SH CPU, refer carefully to the chip specs
- to see if you can say 'N' here. Otherwise, leave it as 'Y'.

- * - Bits 0 and 7 are reserved on SH-3 (_PAGE_WT and _PAGE_SZ1 on SH-4).
- *
- * - Bit 1 is the SH-bit, but is unused on SH-3 due to an MMU bug (the

- * which is the default in cpu-sh3/mmu_context.h:MMU_CONTROL_INIT).
- *
- * In order to keep this relatively clean, do not use these for defining

- * exhausted.
- *
- * - Bit 9 is reserved by everyone and used by _PAGE_PROTNONE.

- * SH-X2 supports an extended mode TLB with split data arrays due to the
- * number of bits needed for PR and SZ (now EPR and ESZ) encodings. The PR and
- * SZ bit placeholders still exist in data array 1, but are implemented as
- * reserved bits, with the real logic existing in data array 2.
- *
- * The downside to this is that we can no longer fit everything in to a 32-bit
- * PTE encoding, so a 64-bit pte_t is necessary for these parts. On the plus
- * side, this gives us quite a few spare bits to play with for future usage.

+ * Linux PTEL encoding.
+ *
+ * Hardware and software bit definitions for the PTEL value (see below for
+ * notes on SH-X2 MMUs and 64-bit PTEs):
+ *
+ * - Bits 0 and 7 are reserved on SH-3 (_PAGE_WT and _PAGE_SZ1 on SH-4).
+ *
+ * - Bit 1 is the SH-bit, but is unused on SH-3 due to an MMU bug (the
+ * hardware PTEL value can't have the SH-bit set when MMUCR.IX is set,
+ * which is the default in cpu-sh3/mmu_context.h:MMU_CONTROL_INIT).
+ *
+ * In order to keep this relatively clean, do not use these for defining
+ * SH-3 specific flags until all of the other unused bits have been
+ * exhausted.
+ *
+ * - Bit 9 is reserved by everyone and used by _PAGE_PROTNONE.
+ *
+ * - Bits 10 and 11 are low bits of the PPN that are reserved on >= 4K pages.
+ * Bit 10 is used for _PAGE_ACCESSED, bit 11 remains unused.
+ *
+ * - On 29 bit platforms, bits 31 to 29 are used for the space attributes
+ * and timing control which (together with bit 0) are moved into the
+ * old-style PTEA on the parts that support it.
+ *
+ * XXX: Leave the _PAGE_FILE and _PAGE_WT overhaul for a rainy day.
+ *
+ * SH-X2 MMUs and extended PTEs
+ *
+ * SH-X2 supports an extended mode TLB with split data arrays due to the
+ * number of bits needed for PR and SZ (now EPR and ESZ) encodings. The PR and
+ * SZ bit placeholders still exist in data array 1, but are implemented as
+ * reserved bits, with the real logic existing in data array 2.
+ *
+ * The downside to this is that we can no longer fit everything in to a 32-bit
+ * PTE encoding, so a 64-bit pte_t is necessary for these parts. On the plus
+ * side, this gives us quite a few spare bits to play with for future usage.

- * Core file format: The core file is written in such a way that gdb
- * can understand it and provide useful information to the user (under
- * linux we use the `trad-core' bfd). The file contents are as follows:
- *
- * upage: 1 page consisting of a user struct that tells gdb
- * what is present in the file. Directly after this is a
- * copy of the task_struct, which is currently not used by gdb,
- * but it may come in handy at some point. All of the registers
- * are stored as part of the upage. The upage should always be
- * only one page long.
- * data: The data segment follows next. We use current->end_text to
- * current->brk to pick up all of the user variables, plus any memory
- * that may have been sbrk'ed. No attempt is made to determine if a
- * page is demand-zero or if a page is totally unused, we just cover
- * the entire range. All of the addresses are rounded in such a way
- * that an integral number of pages is written.
- * stack: We need the stack information in order to get a meaningful
- * backtrace. We need to write the data from usp to
- * current->start_stack, so we round each of these in order to be able
- * to write an integer number of pages.
