thorpej 8abe76d2f0 Add offset and length parameters to bus_dmamap_sync(), used for specifiying 
partial syncs of a DMA mapping.

thorpej 99cc8482d1 Change the last argument of bus_dmamap_sync() from bus_dmasync_op_t to int, 
and allow more than one synchronization operation to be specified in
a single call.  Dissallow mixing of PRE and POST operations.

thorpej fdcd077928 asm -> __asm__ 1997-11-05 00:34:15 +00:00
thorpej 4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>: 
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.
 1997-11-04 23:09:23 +00:00
mark 07db350668 Define __STRING and __CONCAT macros for assembly routines. 1997-10-27 00:28:09 +00:00
thorpej 665f7d1a6e Implement __RENAME() in <machine/cdefs.h> 1997-10-22 05:20:32 +00:00
mark ea1c03acd8 Fix bug in last commit that only worked with cpp -traditional. 1997-10-18 02:46:09 +00:00
mark 1cc95a3df0 Fix .type directives to use #function rather than @function. 
This is due to the problem of the @ character being a single character
comment in the asm assembler. The '#' character has now been chosen
instead for future versions of GCC and GAS so lets conform now.
 1997-10-17 18:27:30 +00:00
mark fb9c150c48 arm32 kernel source restructure

  - Added definitions for ARM8 cpu.
  - Added bus dma support.

Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

leo d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized 
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.
 1997-09-19 13:52:37 +00:00
mark d50cd34639 Remove a dead version of the _MCOUNT_DECL macro. 1997-07-31 00:22:15 +00:00
mark 0e187069c2 The cpu_cahce_*_rng() functions take a start address and a length rather 
than a start address and end address so reflect this in the macros and
prototypes.

mark 663277e00c Simplify cpu option checks now that multiple CPU types are supported in a 
single kernel.
 1997-02-04 06:10:48 +00:00
mark ee02ce0401 Major overhaul of handling of CPU/MMU/TLB specific functions. This allows 
different ARM CPUS with different cache architectures for example to be
supported in a single kernel.
        - All CPU/MMU/TLB specific functions are now held as function
          pointers in a cpu_functions structure defined in machine/cpufunc.h
	  All coproc 15 accesses, TLB flushing, cache cleaning/flushing
          and abort correction functions are now defined in this structure.
        - cpufuncs is a global structure that is setup during initarm()
          that holds all the function pointers for the booted CPU.
	- A global variable 'cputype' now defines the probed cputype.
        - All the existing functions for manipulating CPU specific features
          have been replaced with macros defined in machine/cpufunc.h
          that will call the appropriate function in the cpu_functions
          structure.
	- CPU functions are provided for selected CPU types (config options)
          and the appropriate cpu_functions structure is chosen during
          booting, based on the probed CPU type.
	- All the required functions for existing CPU types (ARM6, ARM7 and
          SA110) have been implemented.

mark 0bebac783d Update for new bus space interface. This implementation is based on 
cgd's alpha implementation. Bus tags now point to a structure of
function pointers to bus space routines rather than being an index to
one of several I/O methods making it simpler and more efficient in
handling many different busses and mapping schemes.
 1997-01-13 00:33:36 +00:00

 1996-12-27 01:55:48 +00:00
cgd 96acdadef7 First step inn removing config_scan() and the hacks that gave devices 
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
