christos | From Felix Deichmann:
While writing "slhci at tc" support, I noticed TC bus_space functions
for alpha don't work as they should (tc_bus_mem.c). Consideration of
dense vs. sparse space seems problematic, especially for widths < 4.
I found information mainly in
[1] https://web-docs.gsi.de/~kraemer/COLLECTION/DEC/d3syspmb.pdf
[2]
http://h20565.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04623255
and a dirty (but tested) hack based on this is attached as an example.
It would be great if someone could have a look and do a cleaner version
preferably.
Especially the end of ([2] section 12.2.2) provides a summary of which
"instruction" to use for which data width in which space, and possible
side effects (unintentional double reads/writes) in dense space...

matt | branches: 1.34.6; 1.34.10;
Do a minor cleanup of alpha (this will make applying pullups post branching
easier).
u_int{8,16,32,64}_t -> uint{*}_t
Change all old-style definitions to C89 prototypes.
Whitespace cleanup.
Constification in db_disasm.c

| 1.33 |

chs | branches: 1.33.2; 1.33.6;
change inline to static inline to appease gcc 4.5.
|
| 1.32 |
| 01-Jul-2011 |
dyoung | #include <sys/bus.h> instead of <machine/bus.h>.
|
| 1.31 |
| 15-Dec-2010 |
matt | rework <uvm/uvm_extern.h> includes.
|
| 1.30 |
| 14-Mar-2009 |
dsl | branches: 1.30.4;
ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
|
| 1.29 |
| 14-Mar-2009 |
dsl | Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
|
| 1.28 |
| 14-Mar-2009 |
dsl | Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

|
| 1.22 |
| 17-Apr-2000 |
drochner | implement bus_space_vaddr()
|
| 1.21 |
| 26-Feb-2000 |
thorpej | - Add a bus space method for getting the translation for a window.
- Add sysarch methods for "get bus window count", "get bus window",
and "pci conf read/write".
These are a hack, but they're what's necessary in order to make
XFree86 work in its current state.
|
| 1.20 |
| 25-Feb-2000 |
thorpej | Add an internal bus space method alpha_bus_space_translate(), which
provides a method to translate an address on an I/O bus into a sysBus
address, along with acccess method information.

ovbcopy -> memmove
|

thorpej | Provide a hook for bypassing space accounting, needed to support ISA PnP
for now.
|
| 1.17 |
| 02-Sep-1997 |
thorpej | branches: 1.17.6;
Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.
|
| 1.16 |
| 23-Jul-1997 |
cgd | branches: 1.16.2;
when i was documenting the bus_space interfaces (the document
was sent to developers, but will eventually become a man page or
something), i noticed a few in various names:
(1) _map and _alloc should take a flags argument, rather than a
'cacheable' boolean.
(2) BUS_BARRIER_* flags should be BUS_SPACE_BARRIER_*.
(3) bus_space_copy_* should be bus_space_copy_region_* for consistency
with other region ops.
Fix all of these (in a backward-compatible way, at least for now). Redefine
internal usees of those names to use the new names. Also, while at it,
clean up the copy functions (remove unnecessary variables) and make sure
that they and other functions conform to the spec.
|
| 1.15 |
| 07-Apr-1997 |
cgd | by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
|
| 1.14 |
| 06-Apr-1997 |
cgd | clean up NetBSD RCS ID strings, include machine/options.h
|
| 1.13 |
| 02-Dec-1996 |
cgd | branches: 1.13.2;
implement bus_space_copy_*().
|
| 1.12 |
| 02-Dec-1996 |
cgd | move barrier operation definition closer to the top of the bus space ops
structure. In the implementations, allow the barrier op to be inlined.
|
| 1.11 |
| 02-Dec-1996 |
cgd | implement bus_space_set_multi_* and bus_space_set_region_* operations.
|
| 1.10 |
| 02-Dec-1996 |
cgd | declare the single-datum read and write methods as inline, so that
the multi and region methods can inline them.
|
| 1.9 |
| 23-Oct-1996 |
cgd | update for new bus.h macros. bus_io_* and bus_mem_* integrated into
single bus_space_* framework. Unfortunately, bus_space_{read,write}_*
operations still imply barriers. That will change soon.
|
| 1.8 |
| 22-Oct-1996 |
cgd | update for new bus.h
|
| 1.7 |
| 09-Jul-1996 |
cgd | clean and update for new defintions, prototypes, etc.
|
| 1.6 |
| 11-Jun-1996 |
cgd | fix pasto in last commit.
|
| 1.5 |
| 11-Jun-1996 |
cgd | since bus_mem_subregion() can return failure, don't even bother to try
to handle the case where subregion offset isn't a multiple of 8.
|
| 1.4 |
| 11-Jun-1996 |
cgd | implement bus_mem_subregion() and bus_io_subregion().
|
| 1.3 |
| 03-Jun-1996 |
cgd | gross hack to get around the fact that there are currently devices with
common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support. As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.
|
| 1.2 |
| 20-May-1996 |
cgd | branches: 1.2.4;
add wbflush() calls in strategic places. These really shouldn't be
here, and there should be a generic 'bus' interface to do memory
read/write barriers.
|
| 1.1 |
| 18-May-1996 |
cgd | TurboChannel bus_mem_* functions. bus_mem_{read,write}_8, and
bus_mem_read_{1,2} are not yet supported for sparse space.
|
| 1.2.4.2 |
| 13-Jun-1996 |
cgd | pull up from trunk:
>implement bus_mem_subregion() and bus_io_subregion().
and:
>since bus_mem_subregion() can return failure, don't even bother to try
>to handle the case where subregion offset isn't a multiple of 8.
and:
>fix pasto in last commit.

Also, a few cleanups and corrections.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
