proper bus_space accesses and some abstraction layer. All drivers that utilised
Gayle also had to be refactored.
I tried not to break anything more, but this clearly needs more testing...
driver. If ACA500 is equipped with supported accelerator with MMU, it allows
running NetBSD on an Amiga 500.
Since ACA is not autoconf-aware, and the probe procedure does not exist yet, the
driver is activated with the ACA500_SUPPORT kernel option. The acahf driver
is commented out in the GENERIC kernel for now (at least until it stops being
very experimental and hackish).
When it comes to ACA-specific hardware, for now the boot CF slot works. Support for everything else is incoming...
for ports which don't bother to have unnecessary bus_dma(9) implementation
to appease MI driver modules that require bus_dma_tag_t.
For amiga, move <m68k/bus_dma.h> inclusion from <machine/pci_machdep.h>
to <machine/bus.h> since amiga will want actual bus_dma(9) in future
for PCI devices.
Fixes builds on sys/modules/if_axe etc on ancient ports.
"Sounds good" from martin@ on port-m68k@.
- The G-REX 4000 and G-REX 1200 are now really supported and working (still only 1st slot but the rest are a matter of time).
- Add bridge identification to p5pb, simplifies the driver and make it more user-friendly.
- Retire P5PB_GENFB and P5PB_OLD_FIRMWARE options, these are now handled automatically, depending on used hardware and firmware.
- Add PCI bus reconfiguration support to p5pb (PCI_NETBSD_CONFIGURE), allows using G-REX without boot to AmigaOS.
- Bring p5pb registers desription up to date with my knowledge.
- Add a lot of debugging code to p5pb (enabled by P5PB_DEBUG kernel option).
- Fix PCI_NETBSD_CONFIGURE in mppb (now it really works).
- Fix quirk handling in zbus.
- Update GENERIC.in and regen the kernel configs.
- Misc cleanup.
- Add bus enumeration and resource assignment (PCI_NETBSD_CONFIGURE) to mppb(4) - no more need to run AmigaOS to configure the bus.
- Add PCI configuration address register to p5pb(4).
- Add PCI I/O space support to p5pb(4).
- Move common code from p5pb(4) and mppb(4) to new pci_machdep.c file.
- Fix style.

This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.
Add missing bus_space(9) methods needed for MI PCI.
Add p5pb(4) - Phase5 PCI bridge driver (and the man page).
Add quirks table to zbus(4) - needed for p5pb.
Change approved by phx.
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Also, merge UCB and Utah copyright texts back into one, as they
originally were.
Extra verification by snj@.
which increases available user address space by 256MB. One file in
pkgsrc/lang/php53 was too large for the amiga. Also remove an old
presumably outdated comment.
to the MD include/cpu.h.
Also make sure that grf_cvreg.h includes cpu.h as it is needed by Xamiga
in xsrc/xfree/xc/programs/Xserver/hw/netbsd/amiga/s3/amigaCV.h.
- move macro SEGSHIFT, NBSEG, and SEGOFSET from <machine/param.h>
to <m68k/pmap_motorola.h> where they should belong
- also simplify NBSEG macro for both 020/030 and 040/060 cases
- also move m68k_trunc_seg(), m68k_round_seg(), and m68k_seg_offset()
(that use SEGOFSET) from <m68k/param.h> to <m68k/pmap_motorola.h>
- add comments about each segment size value used on pmap_motorola
implementation
- add TIA_SIZE, TIA_SHIFT, TIB_SIZE, and TIB_SHIFT macro which can be
used for ste/pte index sizes
- use proper vaddr_t cast instead of unsigned for SEGOFSET/PGOFSET macro
Tested on atari, hp300, and news68k.
They were incorrect since 1997 on amiga and atari, and since 2002
on other ports, but fortunately they don't look so fatal.
Anyway, these values will be moved into <m68k/pmap_motorola.h> soon
since they are quite pmap implementation dependent.
- 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>.
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.
- 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.
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.
