there are two variants of boot.atari per machine types (std or milan)
and they should be selected and copied from /usr/mdec/{std,milan} dirs
to /targetroot during installation.
Problem on default installation with sysinst was reported by David Ross.
Add asm sources which provide a fixed entry point for raw bootxx and bootxxx
because modern aggressive gcc4 may reorder functions in the same source
and the first function in a C source won't always appear at the beginning
in its object.
Also overhaul various files in the stand directory:
- rename stand/Makefile.inc to stand/Makefile.booters and
explicitly include it from each Makefile because the stand
directory contains non standalone programs like installboot and
Makefile.inc will be included implicitly from all Makefiles in SUBDIRs
- put more common options into Makefile.booters so that
all boot programs use proper options (-Os etc.)
- make standalone boot programs compile without installed ${DESTDIR}:
- create machine and m68k symlinks in ${.OBJDIR} in all boot programs
- set appropriate make environments to suppress errors and warnings
- <string.h> isn't there in _STANDALONE case
- put #ifdef TOSTOOLS (looks equivarent with !_STANDALONE)
to some files in stand/tostools
- use ${LD} ${LINKFLAGS} rather than ${CC} ${LDFLAGS}
- create raw binaries on ${PROG} target rather than on beforeinstall
and stop weird renaming on beforeinstall and afterinstall
- print proper error message if bootxx size is larger than limit
- create ${DESTDIR}/usr/mdec/{milan,std} directories on beforeinstall
in all boot programs
(XXX: how can we put MD /usr/mdec/foo directories into src/etc/mtree?)
- prototype warnsfy
- cleanup Makefiles for readablity and remove unnecessary rules
- no need to use daddr_t in installboot because the AHDI label doesn't
support 64 bit block numbers
Tested by David Ross (PR submitter) on port-atari, and
finally NetBSD/atari on TT030 is now fully functional.
Should be pulled up to netbsd-4 (where gcc4 was initially imported)
and netbsd-5.
Rewrite a weird calculation marked "XXX fix calculations XXX"
for an index value of lev2 segment table for the kernel Sysptmap
with more meaningful expressions and PAGE_SIZE independent macro.
Also use "~0" rather than "-1" for an unsigned bitmap value.
Should produce the same results and no functional change.
Tested on Falcon with 68060 by Tuomo Makinen.
via (atari specific) add_sicallback(), as a workaround hack.
Many drivers which use the MD sicallback depend on BASEPRI() macro
defined in <machine/cpu.h> to check nested interrupts,
but functions invoked from MI softint(9) won't run at IPL_SOFT
any longer and the BASEPRI() macro doesn't return expected value
as the past.
Fixes lost interrupt problem on Falcon wdc(4) reported by
Tuomo Makinen on port-atari, and also confirmed by him.
Should be pulled up to netbsd-5.

- change kernel address space layout (i.e. move Sysmap to the end of KVA)
to match other m68k ports, which should be done on yamt-km merge
- rework pmap_zero_page(), pmap_copy_page() and some more other functions
to make them compatible with m68k/pmap_motorola.c
- move pmap_bootstrap() into a separate file to allow using either
the atari pmap.c or the m68k common pmap_motorola.c
- use common m68k include files, pcb.h, pmap_motorola.h, and pte_motorola.h
- misc style and cosmetic changes
Most merge work is done by Tuomo Makinen, and
miscellaneous fixes and cleanups are done by me.
Tested on Falcon with both 68030 and 68060 by Tuomo, and
also tested on TT030 by David Ross on port-atari.
Should be pulled up to netbsd-4 (it requires at least Sysmap changes)
and netbsd-5.
rather than calling brelse(9) after read.
Tested by Tuomo Makinen on port-atari.
Should fix pool panics during installation reported by David Ross

and actually close PR port-atari/39850.
which is now the "API" provided by the pmap module. pmap_kernel()
remains as the syntactic sugar.
Bonus cosmetics round: move all the pmap_t pointer typedefs into
uvm_pmap.h.
Thanks to Greg Oster for providing cpu muscle for doing test builds.
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:
1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.
2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.
I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.
Please commit changes to 'GENERIC.in' and other source files *first*, then
run 'makeconf' and commit the generated files to ensure the 'Created from:'
tags are correct.
Then follow it. Noted by tsutsui@
discussed with tsutsui@ on port-m68k. OK'ed by jdc@.
For atari:
- export ipl2psl_table[] and make it uint16_t
- make makeiplcookie(9) inline
- put PSL_S bit into ipl2psl_table[] rather than adding it in makeiplcookie(9)
- vme/if_le_vme.c: fix a wrong usage of IPL_NET
we no longer need to guard against access from hardware interrupt handlers.
Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.
except the ppbus stuff (which doesn't compile) and ulpt(4) which is
unrelated and can be dealt with separately.
As usual, it comes with related cosmetic changes.
- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

They can be tweaked via sysctl now. Ports that were setting values on
them weren't touched, I only removed the ones that were commented out.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
transfer as a write to ensure the memory is writable before starting any
transfer. The fault status information does not reflect this in the 'read'
status bit (i.e. it shows up as a read access), so faults with a RMW access
to non-writable memory was not getting the correct protection. The page would
be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts
to execute a RMW access to a data page, which is read-only because it's CoP
Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer
and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write
fault bits, and both are set on a RMW access and the trap code was checking
the write status bit.
Fixes PR#36848.
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.
