thorpej | Largely unify the <machine/cpu.h> headers on the m68k platforms.
|
| 1.56 |
| 19-Jan-2024 |
thorpej | Consistently use "intr_depth" as the name of the interrupt depth counter
on m68k platforms.
|
| 1.55 |
| 18-Jan-2024 |
thorpej | Make the M68K_MMU_* defines real kernel options, available in opt_m68k_arch.h.
For 68030, 68040, and 68060, infer M68K_MMU_MOTOROLA. For 68010 and 68020, it
must be an explicit option (set in std.${MACHINE} or, in the case of hp300,
inferred from the specific model option).
|
| 1.54 |
| 18-Jan-2024 |
thorpej | Don't put the MVME1xx model defines into IDENT, make them defflag options and
put them in opt_mvmeconf.h. Make these options depend on the appropriate
M680x0 option (MVME147 -> M68030, MVME16[27] -> M68040, MVME17[27] -> M68060)
so that the CPU option appears correctly in opt_m68k_arch.h.
|
| 1.53 |
| 16-Jan-2024 |
thorpej | Switch mvme68k over to the common interrupt dispatch code and G/C
__HAVE_LEGACY_INTRCNT.
|
| 1.52 |
| 09-Jan-2024 |
thorpej | Remove duplicated / slightly-tweaked loadustp() (load user segment table)
routines from all of the m68k ports using the shared pmap. Instead, in
pmap_init(), set up a function pointer to the appropriate mmu_load_urp*()
function in mmu_subr.s.
|
| 1.51 |
| 23-Nov-2019 |
ad | cpu_need_resched():
- Remove all code that should be MI, leaving the bare minimum under arch/.
- Make the required actions very explicit.
- Pass in LWP pointer for convenience.
- When a trap is required on another CPU, have the IPI set it locally.
- Expunge cpu_did_resched().
|
| 1.50 |
| 22-Aug-2018 |
msaitoh | - Cleanup for dynamic sysctl:
- Remove unused *_NAMES macros for sysctl.
- Remove unused *_MAXID for sysctls.
- Move CTL_MACHDEP sysctl definitions for m68k into m68k/include/cpu.h and
use them on all m68k machines.

mrg | fix PR 6724 - convert m68k options to defflag's. this means that
M680[12346] are now available from opt_m68k_arch.h. FPSP meantioned
in the PR has already been fixed, and i could not find any more.
i built these kernels to ensure i did not break their builds:

atari: HADES FALCON MILAN-PCIIDE
mac68k: GENERIC
sun2: GENERIC
sun3: GENERIC GENERIC3X

rmind | branches: 1.43.2; 1.43.4;
Remove uarea swap-out functionality:
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.
Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).
Discussed on <tech-kern>, reviewed by <ad>.

Merge the ppcoea-renovation branch to HEAD.
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.

jdolecek | Rearrange process exit path to avoid need to free resources from different
process context ('reaper').
From within the exiting process context:
* deactivate pmap and free vmspace while we can still block
* introduce MD cpu_lwp_free() - this cleans all MD-specific context (such
as FPU state), and is the last potentially blocking operation;
all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free()
* process is now immediatelly marked as zombie and made available for pickup
by parent; the remaining last lwp continues the exit as fully detached
* MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same
for both 'process' and 'lwp' exit
uvm_lwp_exit() is modified to never block; the u-area memory is now
always just linked to the list of available u-areas. Introduce (blocking)
uvm_uarea_drain(), which is called to release the excessive u-area memory;
this is called by parent within wait4(), or by pagedaemon on memory shortage.
uvm_uarea_free() is now private function within uvm_glue.c.
MD process/lwp exit code now always calls lwp_exit2() immediatelly after
switching away from the exiting lwp.
g/c now unneeded routines and variables, including the reaper kernel thread
|

clean up some other stuff along the way, including:
- use m68k/cacheops.*, remove duplicates from cpu.h.
- centralize a few declarations in (all the copies of) cpu.h.
- define M68K_VAC on platforms which have a VAC.
- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.

scw | Separate out devices common to many Motorola mvme boards (68k, 88k and ppc)
in preparation for future mvmeppc and mvme88k ports.
This needs a bit if tidying up to make it trully shareable, which will
happen as the new mvme ports are added.
|

| 06-Jul-2001 |
scw | branches: 1.24.2; 1.24.8;
Ditch the `simulated' software interrupt in favour of
hardware-assisted soft interrupts on all boards.
(Note: VMEChip2-less 162/172 not yet tested)
This greatly simplifies the `rei' path and allows
interrupt nesting to be tracked somewhat more easily.
As a result we now have a working CLKF_INTR() macro
and can detect uvm_fault() being called from an interrupt
(although there may still be a very short race detecting
the latter; need to investigate further).

Revamp the bus_space(9) implementation:
. use a structure for the tag instead of an integer constant,
. add bus_space_{peek,poke}_N() (and G/C `badaddr()'),
. fix a few drivers which have dependencies on the implementation.

scw | Add support for the m68060-based machines: MVME-172 and MVME-177.
CPU support taken from a combination of NetBSD/amiga and NetBSD/x68k.
At this time, MVME-172 works but MVME-177 is untested. Since the '177
is otherwise identical to the MVME-167, this should *just work*.
|
| 1.19 |
| 15-Sep-2000 |
scw | Use the complete ethernet address stored in nvram on mvme162/mvme167
instead of faking the first 5 nibbles a'la mvme147.
Apparently recent mvme16x boards have a new 5 nibble prefix...
|
| 1.18 |
| 25-Aug-2000 |
thorpej | Make need_resched() take a "struct cpu_info *" argument. This
causes gives a primitive form of processor affinity. Its use in
roundrobin() still needs some work.

thorpej | First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap
of non-empty run queues), sched_slpque (sleep queues).
NOTE: These may collectively move into a struct schedstate
at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime
(time process on this CPU started running), spc_flags
(replaces struct proc's p_schedflags), and
spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and
a curcpu() macro. Simplify existing cpu_info declarations
where appropriate.
- All references to per-CPU scheduler state now made through
curcpu(). NOTE: this will likely be adjusted in the future
after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

scw | Merge 'scw_mvme68k_bus_space' branch with the trunk.
These changes add support for:
o The MI VMEbus framework on both MVME147 and MVME167.
o Enhancements to the existing MD bus_space(9) implementation.
o Most of the bus_dma(9) API.

thorpej | branches: 1.8.4;
Changes to support fork_kthread():
- cpu_set_kpc() now takes void *arg third argument, passed to the
entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

scottr | Avoid declaring the "astpending" and "want_resched" globals in cpu.h,
as this breaks C++ code that happens to indirectly include this header.
Both Matthias Scheler and I noticed this, independently.
This problem notably does not affect the atari and sun3/sun3x ports,
which have already implemented a similar solution.
|
| 1.6 |
| 12-Sep-1996 |
thorpej | - Use MVME "machine options" to associate MVME models with CPU
options (a'la the hp300 port).
- Declare a "machineid" extern.
- Define constants for machineid, which match the Bug's idea
of MVME model numbers.

|
| 1.12.10.1 |
| 11-Mar-2000 |
scw | Checkpoint of development of the following features of mvme68k:
. Preliminary support for the MI VMEbus framework.
. Full bus_space* and "mostly-there" bus_dma* support.
At this time, MI VMEbus drivers may well work 'as is' on an MVME147 board.
Work to get the MVME167 to this stage is ongoing.
Testers will be required at some point as I have no VMEbus boards which
have existing MI drivers! (Although I am able to test things in a limited
fashion using a noddy driver and a VMEbus RAM card).
TODO:
. Expunge all remaining use of IIOV() and freinds.
. Flag the 'boot device' using bus_space_tag_t and offset.
. Add a 24bit address constraint to bus_dmamem_alloc() (for le/ie)
. VMEChip2 support on MVME167/MVME177
. Support the mvme68k boards in VMEbus slave mode.
. Anything else I can thing of, besides having another beer. ;-)
