b50b3bda1d Add code from i386 to support sysbeep(). Doesn't work quite right but it 
makes a noise.

28c3132268 Linker script for alpha kernel. 1998-07-15 19:19:24 +00:00
Bruce Evans
37889b394a Changed to the C9x draft spelling of the (unsigned) integral type 
suitable for holding object pointers (ptrint_t -> uintptr_t).
Added corresponding signed type (intptr_t).  Changed/added
corresponding non-C9x types for function pointers to match.  Don't
use nonstandard types to implement these types, and don't comment
on them in <machine/types.h>.

8e8c234f4d Don't bother calling pmap_emulate_reference() from cpu_fork(). It isn't 
needed and it panics a DIAGNOSTIC kernel.

1009171eb2 Oops, forgot to modify the pointer-int typedefs from the i386 version. 1998-07-10 02:34:50 +00:00
Bruce Evans
2e480d34aa Added a kernel-only typedef (ptrint_t) giving an integral type that is 
least unsuitable for holding an object pointer.  This should have been
used to fix warnings about casts between pointers and ints on alphas.

Moved corresponding existing general typedef (fptrint_t) for function
pointers from the i386 <machine/profile.h> to a kernel-only typedef
in <machine/types.h>.  Kludged libc/gmon/mcount.c so that it can
still see this typedef.

f71f5262b1 Add the ability to suspend as well as hibernate to the system. This 
is the kernel part of my commits, the userlevel stuff will be done in
a separate commit.  Add the ability to suspend as well as hibernate to
syscons.  Create a new virtual key like hibernate for suspend.  Update
apm_bios.h to define more apm bios goodies.

e6d4206665 Add basic support for 2117x pci chipsets. Currently only pyxis (21174) 
is supported.  Older chipsets will be easy to support later but right now,
I just want to boot my 164LX scratch machine :-).

5aade7d9d3 Define bio_imask to allow the ncr driver to compile. The idea of passing 
mask address around when registering interrupts is wrong IMHO.  We should
use a priority level like IPL_BIO and the lower levels can then translate
it into a mask if they want.
