Use the same undefined-instuction handler on both arm26 and arm32. The handler
...
is derived mostly from the arm32 version, but with a check for an obscure ARM2
bug thrown in.
arm26 fpu and cpu drivers use the new interface for catching undefined
instructions.

Merge setregs() from sys/arch/arm32/arm32/machdep.c,

sys/arch/hpcarm/hpcarm/machdep.c and sys/arch/arm26/arm26/vm_machdep.c
into sys/arch/arm/arm/arm_machdep.c.

Remove CPU_* options (they're in files.arm now -- for some reason I missed
...
this lot in the last commit).
2001-02-25 18:28:27 +00:00
96b16f75a6
Hack to allow arm26 to have its own "cpu" device. This device should really
...
be shared between all ARM ports, but the arm32 one is too ugly for me to
touch it till I've got a test system running.
2001-02-25 15:33:33 +00:00

Reduce the amount of memory allocated for assembler fragments.
...
Excise unnecessary instructions from kernel launch code.
Increase HIMEM on >8Mb machines, since the last two changes didn't free
enough memory to boot with 16Mb.

Reduce unnecessary differences between this and Makefile.arm32.
...
Also (more significantly), use the compiler's default -mcpu setting. This
means I can now build APCS-32 kernels. They work, too.
2001-02-17 17:23:48 +00:00

Re-introduce <arm/endian_machdep.h>, this time using GCC's idea of the target

endianness.

Move cpu_coredump() from arm32/arm32/vm_machdep.c to arm/arm/vm_machdep_arm.c.

Also ANSIfy it and use it on arm26.

Fix a typo in the last change (eh_init_media -> eh_media_init).
2001-02-13 18:20:57 +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.

Since idle() turns up in so many stack backtraces, put it in the global

Adjust the way that media is initialized on DP8390-compatible

chips. The dp8390_softc now has media_init and media_fini
function pointers that do the work.
2001-02-12 18:49:03 +00:00

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

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.

cf_unit usage is now fixed.

Flush out cf_unit abuses.
...
Also, most device functions related to IRQ handling no longer take a device
pointer. We make so many assumptions about the machine's layout in irq.c that
this just seemed silly.

Use a permanent breakpoint to invoke DDB rather than constructing a trapframe
...
manually. Prevents the problem introduced in the trapframe unification
whereby continuing from DDB would cause a panic.

Use evcnts properly for interrupt counting.
...
The architecture here follows that of the vax port -- each device has its
evcnt in its softc, but defers actually incrementing it to the IRQ
dispatcher. This way, devices can attach sub-counts (e.g. Rx and Tx counts
for Ethernet interfaces), but don't all have to have code to increment the
counters.
Drivers deliberately call evcnt_attach_dynamic() before establishing their
interrupt handler so that the establish routine can attach a parent event if
that's appropriate. At present, it isn't.
