- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).
These calls are relatively conservative. It may be possible to
optimize these a little more.
calling pmap_steal_memory() directly. On these platforms, since
uvm_pageboot_alloc() is a wrapper around pmap_steal_memory(), there
is no functional change. This is merely for API consistency.
- Correctly handle striding of data
- Better support for endian neutral access
- Correctly implement _stream variants of bus_space functions that can
byte swap. This reverses the automatic byte swapping done in hardware
for 16 bit ISA bus cards
- re-read RISC/os volume header off disk before writing new label
in case it was updated by installboot utility
- no longer keep a copy of the volume header in cpu_disklabel
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()
Patch written by enami.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate
as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro
for hpcmips, use new bootverbose instead of it's own hpcmips_verbose
Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.
Give rest of clock interrupt code a revamp. Because we are using an external
cycle counter we can now handle loosing several hundred interrupts without
the time slipping.
* For MIPS RISC/os based diskl labels create partition 8 which is used
by sash (and where bootstrap code hides).
* If existing MIPS RISC/os label is present update disk parameter information
consistant with other ports.
Prevent uninitialized time from being written back to the RTC (1-Jan-1970)
if the machine is halted from the root device name prompt
(bootflags & RB_ASKNAME)
All compatable values are copied from the MIPS volume header to the
BSD disklabel structures.
* Add support for writing Mips volume header.
* Remove support for writing NetBSD label directly (this was broken)
These changes allow the kernel to read either a BSD disklabel created under
NetBSD/sparc or a MIPS volume header created under RISC/os.
There is a small amount of losage with the conversion between the 2
types of disk labels (mainly to do with file system types).
A table is used to map partition numbers and types between the two
types, and unless someone does something real fancy (or crazy) it should
work in both senario's
This change will allow the stand alone shell to directly load a NetBSD
kernel and mount a file system, avoiding the need for a seperate disk or
bootp server to bootstrapping NetBSD.
NetBSD/mipsco is now self sufficiant. We are not far from having a
miniroot filesystem and removing the need to have another NetBSD
machine to create the base filesystems.
Minor Trap for young players:
The root partition must be created with 'newfs -O' in order for the
stand alone shell to boot the kernel
TODO:
Add support for writing NetBSD disk labels back in - it will be useful
for non boot disks. I'm just not sure how to control the 2 behavours
- Using the prom getenv function determine the correct console port
- Remove old prom function hooks
- Tidy up bootflags (remove upper case names, fixup RB_ASKNAME) as
recommended by Jaromír Doleèek
handler to hook up device interrupts and softc callbacks.
Suggested by: Jason Thorpe and Toru Nishimura
* Fixup the indenting in a few places to conform to NetBSD style
