tsutsui | Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).
Background:
- All m68k ports have fixed PAGE_SIZE value in their kernels,
but each port uses different PAGE_SIZE value (4096 or 8192)
due to historical reasons.
- Currently module(7) binaries are built per each port so
all m68k kernel sources don't support run-time variable PAGE_SIZE.
- MI <uvm/uvm_param.h> assumes that the port supports a variable
PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
are defined and they have different values.
- On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
for internal optimization.
- m68k ports share userland binaries (especially pkgsrc binaries)
among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
support m68k ports where PAGE_SIZE==8192.
(though this would affect only if static binaries built on
4k page hosts are executed on 8k page hosts)
To solve these inconsistency on PAGE_SIZE definitions,
we should have an independent PAGE_SIZE related definitions
for userland, but it requires major reorganization.
For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.
Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@:
https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035
https://mail-index.netbsd.org/tech-kern/2020/01/thread1.html#025954
Should be pulled up to netbsd-9.

Add dumb memory probe routines for Milan to use all available memory.

Reorganize and bump VM related constants.
- sync VM_MAXUSER_ADDRESS and VM_MAX_ADDRESS with other hp300 derived ports
and use same definitions for USRSTACK as other m68k ports
(no worth to have sun3/sunos compat in these days)
- remove unused KUSER_AREA
- bump MAXTSIZ, MAXDSIZ, and MAXSSIZ
These changes allow my 64MB TT030 build pkgsrc/textproc/icu
which seems to require >200MB VA space.
(note our current 040/060 pmap implementation can't handle >224MB VA size)

thorpej | Minor tweak to the pv_table management in the Hibler-derived m68k pmaps:
The head of the list is now a pv_header, which contains the first pv_entry
as well as a 16-bit attributes field (replaces the pmap_attributes array
plus the pv_entry::pv_flags field) as a 16-bit count of caller-specified
cache-inhibited mappings.
Tested on hp300 (shared pmap_motorola.c), changes to atari and amiga copies
are purely mechanical.

|
| 1.15 |
| 29-Apr-2001 |
thorpej | Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.

Fix I/O access failures for regions allocated by bus_space_map(9) on Milan.
Passing to PMAP_WIRED against I/O spaces seems problematic,
probably after yamt-km branch merge, which was committed
between NetBSD 3.0 and NetBSD 4.0.
(i.e. ISA and PCI devices on Milan didn't work after 4.0 release)
XXX:
According to pmap(9) man page, the "flags" arg for pmap_enter(9)
doesn't take VM_PROT_READ and VM_PROT_WRITE, but pmap_enter()
implementation in sys/arch/m68k/m68k/pmap_motolora.c historically
checks them.
Fix silent hang during config_console() (before consinit()) on Milan.
config_console() was a dirty hack used by ancient m68k ports
to probe and initialize console devices before "real" configure(9),
using subset of configure(9) functions.
In that case, most device specific data (except I/O access method)
are not initialized so we must not access device specific device_t and
softc structures in config_console() cases.
Fix silent hang after isa_intr_establish() on Milan.
The problems (wrong macro replacements) were slipped in rev 1.107:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/atari/atari/locore.s#rev1.107
Handle yet another atari specific quirk in the MI ISA fdc(4)/fd(4) driver.
This makes fd(4) drive(s) (which is necessary for installation)
properly attached on Milan.
atari uses "fdcisa" and "fdisa" for ISA fdc to co-exist other fd(4)
drivers, on-board (atari/dev/fd.c) one and Hades (atari/dev/hdfd.c) one.
Use a proper PSL value to be passed to splx(9) functions.
This should have been changed on yamt-splraiseipl branch merge
back in 2006, which made MI IPL_xxx values independent from
m68k MD PSL values for the %sr register.
Restore piixide(4) for Milan and disable other pciide devices.
piixide was removed in rev 1.18 and the log message said
"because Intel IDE disk controllers only exist as part of
Intel chipsets for x86 systems" but the Milan actually has
the Intel 82371FB southbridge on its board.
Other pciide devices are unlikely necessary for the default
kernel for such a rare machine.
Also fix pasto in comment.
Skip NVRAM checksum check and re-initialization on Milan.
Milan's firmware seems to use different check method.
Ack EOI for IRQ_SLAVE of the master PIC after ack for IRQ of the slave PIC.
I'm not sure if there are possible races in the original code, but
this is what i8259_asm_ack2() in sys/arch/x86/include/i8259.h does
and it looks this change makes a Milan kernel a bit stable.
Replace CRTC register values with ones taken from sys/dev/ic/vga_subr.c.
This fixes noise around column 3 and 4 and makes screen output clearer
on Milan with S3 Trio64V.
Explicitly setup the secondary IDE interrupt of PIIX on Milan.
The secondary IDE interrupt is connected to MBIRQ0 on PIIX, but
the Milan's ROM bootloader (at least version 0.99.7) doesn't seem
to setup the MBIRQ0 register to route it to IRQ15.
On Milan, also explicitly disable MBIRQ1 on PIIX.
Milan's ROM bootloader v1.2 and v1.4 incorrectly set MBIRQ0 connected
to the secondary IDE to IRQ14 (not 15) and unused MBIRQ1 to IRQ15,
so both IDE channels don't work properly.
Add dumb memory probe routines for Milan to use all available memory.
Tested on Milan with 32Mx1, 32Mx4, 128MBx1, and 128MBx3.
(bootloader ROM fails to load TOS with 128MBx4)
No particular comment on port-atari@:
http://mail-index.netbsd.org/port-atari/2018/02/09/msg000580.html
Provide wdboot as a copy of sdboot for Milan.
It looks Milan's bootloader ROM emulates IDE disks as SCSI disks
so sdboot works for them, but atari's installboot checks a specified
device name and requires wdboot for wd(4) devices.
Fix another possible out of bounds.
Replace bus_dmamap_sync(9) op with a newer one taken from m68k/bus_dma.c.
This could fix memory corruption issue caused by PREREAD ops with regions
whose boundaries are not aligned at cacheline size.

Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).
Background:
- All m68k ports have fixed PAGE_SIZE value in their kernels,
but each port uses different PAGE_SIZE value (4096 or 8192)
due to historical reasons.
- Currently module(7) binaries are built per each port so
all m68k kernel sources don't support run-time variable PAGE_SIZE.
- MI <uvm/uvm_param.h> assumes that the port supports a variable
PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
are defined and they have different values.
- On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
for internal optimization.
- m68k ports share userland binaries (especially pkgsrc binaries)
among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
support m68k ports where PAGE_SIZE==8192.
(though this would affect only if static binaries built on
4k page hosts are executed on 8k page hosts)
To solve these inconsistency on PAGE_SIZE definitions,
we should have an independent PAGE_SIZE related definitions
for userland, but it requires major reorganization.
For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.
Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@:
https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035
https://mail-index.netbsd.org/tech-kern/2020/01/thread1.html#025954
Should be pulled up to netbsd-9.
