Also, put the cpu_decl()s in cpuconf.h, so that platform support files
can pull in the prototypes from there, and pull in options for those
systems for which there is code in the source tree.
at least 8-). Add structure offssets for structure members, so we
know how much space we're using. Make the version in the bootinfo
structure be a u_long, so there's no implicit padding in the structure.
Add a few more pointers to the bootinfo v1 structure, which will all
be set to NULL for now.
was sent to developers, but will eventually become a man page or
something), i noticed a few in various names:
(1) _map and _alloc should take a flags argument, rather than a
'cacheable' boolean.
(2) BUS_BARRIER_* flags should be BUS_SPACE_BARRIER_*.
(3) bus_space_copy_* should be bus_space_copy_region_* for consistency
with other region ops.
Fix all of these (in a backward-compatible way, at least for now). Redefine
internal usees of those names to use the new names. Also, while at it,
clean up the copy functions (remove unnecessary variables) and make sure
that they and other functions conform to the spec.
(1) it was using 'max', and some functions use a variable
of that name (*sigh*), and
(2) that makes it easier to be a bit trickier, and only call
swpipl if changing the IPL.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
__builtin_classify_type() into harmless values, so that lint doesn't
get confused, think they're real functions, and that they're being
invoked in the wrong ways.
using __weak_alias in libc, __indr_reference should probably be defined
to do nothing (but defined, so that duplicate functions/variables aren't
compiled). However, when not using __weak_alias, __indr_reference causes
them to be omitted completely, which is a lose. So, until weak aliases
are going to be used, don't define __weak_alias or __indr_reference.
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.
rather than and-ing 16G-1. That just strips the k0seg bits, rather
than making the false assumption that the physical address is going
to be in the lower 16G. That doesn't apply for CIA device-space
addresses, for instance.
deleting (and cleaning up) N pages of #ifdefs in machdep.c. While we're
at it, make the cpu type options generate flags, and check them instead of
kernel Makefile defines.
create an assembly label, and SYSCALLNUM to convert a syscall name into
the macro that's defined to be its number. Add a CALLSYS_NOERROR macro
which invokes the named system call. (CALLSYS_NOERROR is here since
it's used in locore, for sigcode.)
consistency with the way machdep headers for other things are done.
(the creation of the ecoff_machdep.h files was done on the CVS server, to
keep the RCS logs intact.)
macros to use to remove #ifdefs from the machine ID case check.
Eventually, these headers will contain other information, e.g.
machine-dependent relocation information, etc.
and IEEE S and T floating datum loads and stores. VAX floating data
types not yet supported, and in the future will only be supported if
FIX_UNALIGNED_VAX_FP is defined. (No point in wasting the space when
most of the time there will never be VAX FP loads and stores.) Right
now, these features can be controlled only by sysctl. The (boolean)
integer sysctls machdep.unaligned_print, machdep.unaligned_fix, and
machdep.unaligned_sigbus control printing about unaligned accesses
(defaults on), fixing up of unaligned accesses (defaults on), and
forcing a SIGBUS on unaligned accesses (defaults off). If an access
is not fixed up (for lack of method or explicit decision), a SIGBUS is
always generated to keep programs from using bogus data. At some point,
these three choices should be controlled by per-process flags, as well.
more naturally in terms of way the OSF/1 PALcode delivers traps and
interrupts. Clean up fault/exception handling code and system entry
points. Seperate ASTs into a seperate C function.
(2) Restructure and improve machine check and correctable error
handling based on information in the 2nd Ed. of the Alpha Architecture
Reference Manual.
(3) Removed unused (and not likely useful) PALcode assembly stubs.

clean up some, and add prototypes for all of the CPU instruction and

alpha_cpu.h, and this file is no longer necessary for the
Alpha. However, some machine-independent code (e.g.
/sys/compat/common/kern_exit_43.c) still wants a file with
this name to be around.
from the mach3 versions only as much as necessary to allow the old
NetBSD/Alpha pmap code to compile. THESE WILL NOT WORK AS-IS, and at
minimum will require code to implement reference- and modified-bit
emulation.
This is a bit of a hack, as-is, since there's a lot of code that's
outright duplicated between the various files and because it doesn't
support detection of a network device as the root device. The
latter's not a problem yet, because NetBSD/Alpha can't load the kernel
from the network to begin with.
common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support. As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.
documentation I have calls them, and update for new definitions in
sys/exec_ecoff.h. Also, fix ECOFF_SEGMENT_ALIGNMENT macro so that it
actually returns the right alignment.
reasons: it won't attach as console, and there's currently no way to do
keyboard input on TC machines), and has no real RAMDAC (colormap, cursor,
etc.) support. Digital UNIX does not support CFB frame buffers in the
Alpha, but they appear to work OK (with an appropriate monitor) in my
3000/300.
