Checking a whole host of pmap changes:
...
Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.
Also implemented a page zeroing function when the processor is idling. Note that hpcarm may wish to disable this.
I believe this code to be stable, if anyone has any problems please shout up.

Initial commit for merging A7000/NC with the RISCPC in order to get _one_
...
bootable GENERAL kernel for the 3 machines.
This is done by integrating the ARM7500 in a better way. In various places
the IOMD ID is checked and action is taken at runtime compared to
compiletime.
The small piece of assembler that is changed now uses the flag
`arm7500_ioc_found' that is set up by iomd.c at startup. When this chip
isnt found at startup it will skip reading the ARM7500 extended IRQ
registers and wont clear them either.
The next step will be getting the mode-definition files to the bootloader.
Currently they are compiled in.

Add a pmap_map_ptes function to map another process page table entries into the current pmap (similair to pmap_pte) but this allows multiple use of it, rather than repeated calls of pmap_pte for pte, map_ptes returns a pointer to the va where the entries were mapped so it can be reused ptes can be found by indexing into it.
...
Update some of the functions that use pmap_pte to pmap_map_ptes.
Note that there's a dummy macro for pmap_unmap_ptes, this is because at some point locking will be needed, so we need to be able to unlock them.
Performance gain seems to be minimal, however long term it should help improve things.
This is similair to the i386 pmap_map_ptes, however it's based on a version from Richard Earnshaw.

Move cpufunc stuff from arm32/arm32 to arm/arm. The only change involved is
...
to add recognition of the SA-1100 and SA-1110 for compatibility with hpcarm

Be consistent with limit constants:

- use "U" suffix for unsigned constants
- use "L" suffix for long constants
- use "UL" suffix for unsigned long constants
- use hexadecimal instead of decimal
Fixes build problems with vi (now that warnings/errors are enabled) on
mips, powerpc and arm platforms.

* Move definitions of exact-width integer types from <machine/types.h>
...
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
intmax_t, pointer-type and size_t arguments.

These calls are relatively conservative. It may be possible to
optimize these a little more.

Change the value of tf_pc in undefined-instruction handlers on arm32. It now

2001-03-13 20:22:02 +00:00
ce5529eabf
Change undefined instruction handler to use a linked list for each

co-processor. This is necessary so we can have several handlers for
CP0 (used as a catch-all for non-CP instructions).
Handlers are now removed using remove_coproc_handler(), rather than by calling
install_coproc_handler() with a NULL handler.
Because install_coproc_handler() can now allocate memory, there's a version
for use at boot time that doesn't.

Re-introduce <arm/endian_machdep.h>, this time using GCC's idea of the target
...
endianness.
2001-02-17 14:55:44 +00:00
9b6de1da90
Move cpu_coredump() from arm32/arm32/vm_machdep.c to arm/arm/vm_machdep_arm.c.
...
Also ANSIfy it and use it on arm26.
2001-02-13 22:54:25 +00:00
e07c392eed
Fix typo in header filename.
2001-02-13 14:11:30 +00:00
284047a2b2
Move sendsig() and sys___sigreturn14() from arm26/arm26/vm_machdep.c and
...
arm32/arm32/machdep.c into arm/arm/sig_machdep.c, merging and ANSIfying in
the process.
The code is based on the arm32 version, so I don't think anything should break
there.
2001-02-13 13:19:52 +00:00
a4e55e0f13
Shared ARM ptrace(2) implementation. Mostly the same as the arm32
...
version, but with some #ifdefs for arm26.
Also, don't define PT_STEP, since we don't implement it. This should
reduce code size a little.
2001-02-11 17:03:04 +00:00
9826a76781
Common <arm/reg.h> (and hence common struct reg) for ARM.
...
This is theoretically backward-incompatible on arm26, but GDB doesn't work there
yet anyway.
2001-02-11 14:51:55 +00:00
1178bf4219
Initial potentially sharable <arm/armreg.h>. Used by all arm26 code.
2001-01-22 22:10:39 +00:00
8805bd8b56
Unify arm26 and arm32 trapframe structures. The unified trapframe is the same
...
shape as the old arm32 one, but there are a few #defines to keep arm26 code
happy. Anything that depends on the precise shape of the trapframe,
and especially on being able to treat it as an array of registers, has been
updated.
2001-01-20 17:14:19 +00:00
2c20803b63
Add extra constants defined by ARM ELF revision B01.
2001-01-18 23:50:50 +00:00
48f4b0ea72
Tidy up some comments.
2001-01-18 21:54:28 +00:00
2c89ce7e74
Add <arm/frame.h>, for shared stack frame structures. Currently, only sigframes
...
are common.
2001-01-18 21:48:25 +00:00
6b017eaa04
Add ARMv5 instructions: BLX, CLZ, BKPT, MCR2, MRC2, CDP2, LDC2, STC2.
...
Also correct a comment.
2001-01-18 21:41:09 +00:00

A bit of extra discussion based on the latest ARM ARM.
2001-01-18 20:42:03 +00:00
8df387473f
Move <machine/signal.h> into shared directory.
2001-01-13 17:02:36 +00:00
70d40a123c
Make db_disasm_interface const.
2001-01-13 16:53:27 +00:00
f52101bc64
Make all the disasm_interface_t arguments const, thus allowing us to
...
allocate them statically in the text segment. Do so for disassemble().
2001-01-13 16:52:01 +00:00
792b8500bc
ANSIfy, un-__Pify, and in the case of disassem.c, add an RCSID.
2001-01-13 16:44:25 +00:00
78c0ba909e
Separate out sigcode into its own file, since it's shared by arm26 and arm32.
2001-01-13 00:06:50 +00:00

Storing four-byte pointers to two-character strings is silly. All the
...
auxilliary tables used by the disassembler are now char[][].
The main table still uses pointers because:
- the longest instruction name, "imbrange" is >7 characters long, which would
make the field length wasteful.
- GCC spots that most of the formats are shared and makes them pointers to the
same string, so turning them into char[8] would be counter-productive.

Move all the nasty big tables into the text segment. This isn't much use in
...
the kernel at present, but maybe one day when we have a ROMmable kernel...
2001-01-12 22:44:08 +00:00
cdae07e857
Correct comments (the code does support LDF, STF, LDC, STC).
...
Support BX (for completeness).
Correct spelling of SWP.
2001-01-12 22:19:15 +00:00
e9bb2a7916
Correct immediate constant handling: bits [11:8] are a rotation, not a shift.
...
Also add support for the "P" modifier to TEQ, TST, CMP and CMN, and don't
bother displaying the "S" bit for these instructions.
Together, these correct the disassembly of 0xe33ff3c2 (an instruction in
arm26 irq_handler() from "teqs r15, #0x08000000" to "teqp r15, 0x08000003".
2001-01-12 21:56:18 +00:00

Prototypes for disassemble_readword() and disassemble_printaddr().
2001-01-12 21:35:48 +00:00
a5ef6e1f81
Move db_disasm.c into sys/arch/arm/arm. Use arm26 version, since it should
...
generate smaller compiled code.
2001-01-12 21:31:51 +00:00
a4047bf10c
Move the generic ARM disassembler from arm32/arm32 to arm/arm.
2001-01-12 13:43:11 +00:00
6fa98146d5
Start merging actual code in arm32 and arm26:
...
arm32/arm32/in_cksum_arm32.c -> arm/arm/in_cksum_arm.c
Also move specification of other checksum stuff to files.arm, even though we
use the MI code for that.
2001-01-11 23:27:26 +00:00

Share <machine/elf_machdep.h> between arm26 and arm32.
2001-01-11 22:28:06 +00:00
dc037466f5
Install all the headers (arm32 does).
2001-01-11 21:05:03 +00:00
1add2fd369
Remove <arm/endian_machdep.h>, since we might get a big-endian ARM port
...
some time.
2001-01-11 21:03:10 +00:00

... this one's utterly pointless though.
2001-01-10 19:05:46 +00:00
29de7da78b
Header files which don't differ between arm32 and arm26 and can thus be
...
shared.
2001-01-10 19:02:05 +00:00

Empty file to keep config happy.
