Add a preliminary CD boot support to uboot for preparation of PR/54455.

Briefly tested on mame, but not enalbed yet.

(tsutsui)

Use proper signedness for the LIF file system data structures.

Ancient 4.3BSD used short and int for location, file size, file type,
and addresses etc. but all of them should be unsigned.
Also rename several variables and add comments for readability.

The LIF file system info can be found in "The HPDir Project" page:
https://www.hp9845.net/9845/projects/hpdir/

The same uboot.lif binaries are generated.

(tsutsui)

Rename ${PROGAOUT} -> ${PROGELF} to reflect reality.

(tsutsui)

Misc cosmetic changes for mostly readability.

- KNF and add some newlines per blocks
- define and use proper bintobcd() macro
- make local functions and variables static

The same uboot.lif binaries are generated.

(tsutsui)

Fix "stray level 1 interrupt" panic by pressing keys during autoconf(9).

Also explicitly initialize sc->sc_status = HIL_STATUS_BUSY in hil_attach().

Previously hil_intr(9) returned immediately during 'cold', but
all interrupts are enabled at the end of configure() (actually
in MD cpu_configure()) and cold is cleared in confiugre2()
after configure(), so there is a small window when hil interrupts
can be triggered during cold.

It looks there is no problem to process hil_intr() before
hil_attach_deferre() is called via configure2() because
we already check 'sc->sc_status != HIL_STATUS_BUSY' on
processing a kthread.

Note this seems also to appease the similar panic on mame's hp9k370
emulation (though mame's emulation around DMAC looks still incomplete).

Should be pulled up to netbsd-10 and netbsd-9.

(tsutsui)

Fix integer overflow of strtol(3) for "loadpoint" address on ILP32 hosts.

This strtol(3) was introduced in rev 1.12 for PR/57909 after netbsd-10,
but it returns LONG_MAX (0x7FFFFFFF) for 0xFFF00000 on ILP32 hosts and
the wrong loadpoint causes "NOT ENOUGH MEMORY" error by the BOOTROMs
on loading uboot.lif on (at least) my 9000/360 and 9000/425t.

(tsutsui)

Note about recent hp300 topcat(4) framebuffer improvements.

(tsutsui)

Add comments about quirks of 98542/98543 framebuffers with 1024x400 pixels.

(tsutsui)

Add 98542 and 98543 framebuffers to supported "Graphics Devices" section.

I hope someone will sync a list of supported devices in port wiki pages
with one in this installation notes.

(tsutsui)

Note that 98542 and 98543 variants are also supported by topcat(4).

(tsutsui)

Fix topcat(4) problems on some models that cause garbages on screen.

- Make sure that windowmove (hardware BITBLT) ops complete by checking
  tc_busywait() before calling putchar functions by MI rasops(9).
  It looks CPU accesses against VRAM during windowmove (copy, erase,
  and cursor) ops causes unexpected garbages at least on 98543 on HP360,
  98547 on HP370, and also on 98543 on 040 HP380 (but not on 98549).

- Handle 'sparse VRAM' on 98543 (and probably 98542) properly:
- Prepare and use own topcat_putchar1_4() function for sparse VRAM.
- Pass proper 'VRAM width' rather than actuall font width to all
  windowmove (copycols, erasecols, copyrows, eraserows, and do_cursor)
  operation functions.

Now all topcat(4) consoles on 98543 on HP360/HP380 and 98547 on HP370
work fine, and no visible regression on 98549 on HP380 and 98544 on HP360.

Worth to pullup netbsd-10.

(tsutsui)

Add DELAY(9) to make palette register settings stable on 98543 in HP360.

Note 98547 (6 bpp variant) on HP370 (68030 33MHz) doesn't need these
DELAYs so maybe only some old variants (98543 and 98545?) on 020/030
have such restriction (actually only one nop seems enough.)

(tsutsui)

Fix another fatal typo that prevents dma(4) interrupts.

(tsutsui)

Fix fatal typo that prevents all intio devices probed.

(tsutsui)

Check tc_waitbusy() before writing palette registers in topcat_setcolor().

This seems to make palette operations more stable on my HP360 with HP98543.

(tsutsui)

Use proper planemask per a vaild number of planes.

(tsutsui)

Fix MD allocattr to return proper attributes what MI rasops(9) expects.

(tsutsui)

Move a check of topcat(4) specific fb width quirks to topcat.c.

We need to check fb->planes but it's propbed in topcat.c after
common diofb_fbinquire() is called.

Also add a comment that it looks these 1 bpp and 4 bpp boards have
VRAM with sparse address layout and we have to handle
512 pixels per line with 1024 bytes per line.

(tsutsui)

Increase DELAY() for waitbusy macroes as pre-wscons and 4.4BSD did.

It looks necessary for sane palette ops at least on HP98543 topcat
on 68030 HP 9000/360.

(tsutsui)

Don't panic as a fatal error on receiving packets with invalid length.

Such errors could happen on aged and fragile 10BASE-2 hub etc.

(tsutsui)

Use LINKS to create hard links to generate proper METALOG files.

Also use the default ${PROG} variable and "install" target.

Fixes PR port-hp300/58211.
Should be pulled up to netbsd-10 and netbsd-9.

(tsutsui)

Disable dmf* and dmz* entries and add warns "not integrated yet."

Also note tty[EFGH]? have been used by MI wscons and new tty node names
should be assigned once dmf(4) is committed.

Also put back libfb.a in xorg_server_ver=110 case.

It looks required only on building Xorg server binary and
unnecessary for release (actually marked as obsolete only on vax),

and most ports will be switched to Xorg 1.20 soon.

(tsutsui)

Replace DELAY() with one in hp300 bootloader and adjust cpuspeed counts.

Fix boot failure on my ancient Seagate ST52160N drive.
It looks some of such old drives can't respond to SCSI
test-unit-ready command without proper wait after SCSI bus reset.
Bump version again to denote a fix.

XXX we should re-evaluate cpuspeed counts for DELAY() in bootloaders
    (where cache is disabled) on other m68k ports, hp300 and luna68k etc.

(tsutsui)

Port rasops'fied smg(4) framebuffer driver for VS3100 from OpenBSD/vax.

This allows using more fonts other than 8x15 pixels on smg(4).
Tested on my VAXstation 3100/m30.

Note the bitorder of smg(4) VRAM is LSB first (i.e. LSBit is the
most left side pixel) and this requires more complicated changes
to bitmask ops in MI rasops(9) because several LE machines have
VRAMs whose MSBit is connected to the most left side pixel,
but for now I prepared smg(4) specific putchar and cursor ops
based on old luna68k omrasops.

(tsutsui)

(tsutsui)

Request only 36 bytes for a response of INQUIRY command for legacy drives.

Some drives don't respond larger requested size for newer
SCSI3 devices and not all drivers can handle short xfers.
We should fix drivers to handle such short xfers properly,
but we need only SCSI device type here (and the 36 bytes are
enough even if we want vendor and product names on a bootloader).

The problem is reported from Andreas Grabher (a maintainer of NeXT
Computer Emulator)a on port-next68k@:

(tsutsui)

Remove trailing spaces and TABs.

(tsutsui)

Remove leftover "last kernel PT page" settings derived from hp300.

Whilehere, also remove VM definitions for obsolete COMPAT_HPUX stuff.

All hp300 machines has RAMs at a region from the highest address
i.e. 0xFFFFFFFF to smaller address (as HP claims "it's the MSB first"),
so kernels have to prepare PA==KVA mappings as the "last PT page" to
guarantee the running kernel works both before and after the MMU is
turned on.  For such a special mapping, we have to set up necessary
segment table and page table during early startup, in pmap_bootstrap()
invoked from locore.s.

On the other hand, NeXT machines have RAMs at a region from 0x40000000
to below (i.e. to larger address) so we still need a PA==KVA mapping.
However currently NetBSD/next68k just uses the transparent translation
registers to achieve the PA==KVA mapping, so unlike hp300 we don't have
to prepare special segment table and page table for it.

Note many other m68k ports (like luna68k, news68k, x68k etc.) have
RAMs at a region from 0x00000000 so usually we can assume PA==KVA
and don't have to bother to prepare such speicial mappings.

No user visible changes (except now freed wasted pages for the tables).
Tested on my NeXTstation slab.

during ncr53c9x_intr() for esp(4) at ipl 3.  It worked on netbsd-5
and prior, but on netbsd-5 splbio() was changed from ipl 3 to 6
for SMP support and on netbsd-6 ncr53c9x driver was changed to
use mutex(9) instead of simple_lock(9), so nextdma interrupts
were no longer raised during ncr53c9x interrupt handler.

For now, just call mutex_exit(9) and mutex_enter(9) during
waiting nextdma(4) interrupts in MD esp_dma_intr() handler.
This could be wrong and the interrupt handler for nextdma should
be reorganized, but it just works.

Should be pulled up to netbsd-10 and netbsd-9.

next68k: Specify proper constraints for bus_space_read region and multi ops.

These functions write the read data into memory at a specified pointer,
but without the "memory" constraint gcc could optimize out these ops
if the memory is allocated on local stack.

With this fix nextkbd(4) works again.

Should be pulled up to netbsd-10 and netbsd-9.

(tsutsui)

next68k: Fix delay_divisor value for proper delay(9) on 68040.

(tsutsui)

Fix link errors now complained by new ld(1) from binutils 2.39.

(tsutsui)

No need to link shared libXext here.

(tsutsui)

Remove obsolete bpf entries not neceerary for clonified bpf(4).

Fixes "MAKEDEV: bpf8: unknown device" errors.

(tsutsui)

TAB/space cleanup.

(tsutsui)

TAB/space/indent cleanup.

(tsutsui)

Make sure to call wsfont_init(9) as other framebuffer drivers.

Otherwise wsfont_find(9) always fails and wsdisplay(4) is not attached.
XXX: still no output on the framebuffer console on my VAXstation 3100/m30

(tsutsui)

TAB/spaces/indents cleanup.

(tsutsui)

Disable (comment out) options DIAGNOSTIC in INSTALL kernels.

It has been there since the initial revision 1.1 while
it was disabled in GENERIC in revision 1.121 back in 2002:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/mac68k/conf/GENERIC#rev1.121

Briefly discussed in PR/57107, and maybe should be pulled up to
netbsd-9 and netbsd-10.

(tsutsui)

Fix out of bounds invalidate (and writeback) in bus_dmamap_sync(9) ops.

Detected by the POOL_REDZONE check in sys/kern/subr_pool.c that
has been activated if options DIAGNOSTIC is enabled on post netbsd-9.
The extra invalidate on DMASYNC_PREREAD op discards redzone pattern
data allocated right after an mbuf cluster without proper writeback
to memory so that it triggers false redzone assertions on freeing mbufs.
This bug was my botch in rev 1.25 committed 15 years ago. (sigh)

Fixes PR/57107 (kernel panic on -current when configuring network
with sn(4) on mac68k), as actually the bus_dma(9) op changes
in the past days were introduced for mac68k sn(4) improvements
by using the MI SONIC (src/sys/dev/ic/dp83932.c) driver.
https://mail-index.netbsd.org/port-mac68k/2007/06/01/0001.html

Should be pulled up to netbsd-9 and netbsd-10.

(tsutsui)

Enable UFS2 support.

Tested on 425t with HPDisk emulating 7958B using NetBSD 9.3 UFS2 image.

(tsutsui)

Make hp300 bootloaders UFS2 ready.

(tsutsui)

Remove a #if 0'ed out unused function.

(tsutsui)

Cleanup extern declarations.

(tsutsui)

Enable options DISKLABEL_EI by default as amd64.

No particular comment no port-i386@:
https://mail-index.netbsd.org/port-i386/2022/12/02/msg004063.html

(tsutsui)

Explicitly include <sys/kernel.h> for hz(9) as man pages says.

XXX: it looks sys/param.h r1.615 and later also has extern int hz

(tsutsui)

Add empty DIOCCACHESYNC ioctl(2) for rd(4).

Without this raid(4) always complains on various raidctl(8) ops:
> raid0: cache flush[0] to component 0 failed (22)

RAID1 configured by raid(4) just works HP-IB disks on hp300.

(tsutsui)

Misc KNF and cosmetics.

(tsutsui)

Remove more duplicated static function declarations.

(tsutsui)

Use proper RAW_PART macro rather than a magic number.

(tsutsui)

Set disk_geom parameters required by DIOCGPARTINFO in disk_ioctl().

With this change raid(4) no longer complains before mountroot:
> RAIDframe: can't get disk size for dev rd0 (22)

Should be pulled up to netbsd-9.

(tsutsui)

Remove a duplicated static function declaration.

(tsutsui)

Pass a correct dev_t arg to disk_ioctl().

Probably harmless.

(tsutsui)

Check bounds of each partition by MI bounds_check_with_label(9).

The previous implementation was committed in rev 1.26 about 26 years ago
and it looks there is no quirk to use the old MD one.

(tsutsui)

Check bounds of RAW_PART by bounds_check_with_mediasize() as other drivers.

With this check, dd(1) without a count value against a raw partition
is terminated properly at the end of media.  Tested on 425t and HPDisk.

Should be pulled up to netbsd-9.

(tsutsui)

Fix silent bus error panic on 98543A topcat framebuffer on HP320 and HP360.

It looks DELAY(100)s before checking cmap_busy in old pre-wscons grf_tc.c
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/hp300/dev/Attic/grf_tc.c?rev=1.42
are actually necessary on 68020 (HP320) and 68030 (HP360) machines,
while it works without them on 68040 (HP380).

Should be pulled up to netbsd-9.

(tsutsui)

Misc KNF and cosmetics.

No binary change.

(tsutsui)

Remove unnecessary declarations.

(tsutsui)

Service mode switch should not be treated as an error.

Use aprint_normal(9) to avoid confusing dmesg.

(tsutsui)

Sync with rdreg.h integer type changes.

(tsutsui)

Use proper integer types for HP-IB xfer parameters.

No visible regression on 425t and HPDisk.

(tsutsui)

Remove now unused buffer members from softc prepared only for rdreset().

(tsutsui)

Fix "rd(4) at punits not configured on HPDisk are misprobed" problem.

- check not only stat value returned by C_QSTAT command against
  each punit but also desc.d_name returned by C_DESC command
  because it looks HPDisk responds to commands against punits supported
  but not-configured punits at 1-3
- prepare rdreset_unit() function to manage reset punit ops during
  probe without valid softc

The stragety is taken from OpenBSD with several modification.
Tested on 425t with real 9122D and HPDisk emulating two 7937H drives.

Should be pulled up to netbsd-9.

(tsutsui)

Use explicit struct to represent RX queue buffer data structure.

No binary change.

Maybe the similar change should be applied to MI com(4) and zsc(4)?

(tsutsui)

Use common macro for numbers of cylinders and blocks for HP-IB disks.

No binary changes.

(tsutsui)

Make local functions and variables static.

(tsutsui)

Make local variables static and read only ones const.

(tsutsui)

Sync a list of HP-IB disk IDs with kernel's one.

Now bootloader can boot from 2202A, 7908A, 7911A, and 7941A.
Tested on 425t and HPDisk.

(tsutsui)

Use complete cpu name strings for readability.

(tsutsui)

Use a consistent pointer variable.  No functional change.

(tsutsui)

Remove global hwplanecount and use ri_depth in struct rasops instead.

No functional change.

(tsutsui)

Set an actual framebuffer depth (bpp) to rasops ri_depth.

The previous value was derived from OpenBSD/luna88k but
it has not been referenced even via ioctl(2).

(tsutsui)

Explicitly limit a number of rasops rows per size of rowattr[].

(tsutsui)

Remove trailing whitespaces.

(tsutsui)

Use C99 designated initializers.

(tsutsui)

Make local functions static.

(tsutsui)
