Geert--

Recent (non-official) MkLinux kernels support /dev/adbmouse (busmouse
emulation).  GPM works with it, so I suspect that XF68_FBdev would as
well.  Choice #2 does seem the least amount of work.

One question--would acceleration would still require framebuffer
devices?

Mark Hatle ported /dev/adbmouse to mklinux last february. It wasn't
available in DR3 but I believe that it's available in the GENERIC
mklinux kernels.

Well, globegate GENERIC kernels have the slightly-better then current
adbmouse driver from linuxpmac (does macx mice w/o problem).

Did you fix the problem with the non-working option (alt) keys?
In the XF68_FBDev of the new R5beta linuxppc, it is still there.
For me (PM6400, standard Apple keyboard and 1-button mouse), XF68_FBDev
is pretty much useless. 

If you need more information to get to the bottom of this problem, just
say what kind of tests to perform.

Nice.

> One question--would acceleration would still require framebuffer

No. Xpmac does it without frame buffer devices: it just mmap()s /dev/mem. All
that has to be changed is the interface to the frame buffer device API: instead
of asking the frame buffer device for address and size of frame buffer and MMIO
region, and mmap()ing that, something else has to be done.

One other thing to consider is video mode programming. XF68_FBDev uses
modelines (except for `mode "default"'), while Xpmac can take a vmode and cmode
argument. But I think this can be solved by putting the Modeline <->
vmode/cmode conversion routine in XF68_FBDev (cfr. drivers/video/macmodes.c).

And of course there won't be support for virtual screens, as the vmode/cmode
API doesn't provide for this.

Problem is that I don't know anything about ADB, nor have ADB devices :-(

Simple question: What is the advantage of fbdev server without
 frame buffer device ?

Please note I am NOT against this project. More possible selection
is better.

I wouldn't call them non-official... they're just non-Apple.  They're at
least somewhat sanctioned.  :-)

This would be a better long-term solution, though I would find it more
palatable to add an FB-style interface to the existing drivers, adding
whatever additional functionality is necessary rather than dumping the
existing drivers (since switching to the LinuxPPC drivers would probably
mean dropping x100 support, or else rewriting those drivers from scratch). 
Note that this is a couple of notches down in priority for me (as far as
my time goes), but anyone else interested in working on it can feel free.

vmode ioctl stuff?  Since when does MkLinux support detecting or changing
video modes?  This is where we're going to run into trouble either way.
This particular support code needs to be written.  In the process, it
would be logical to make it support both a framebuffer interface and the
traditional interface for compatibility with older vmlinux servers.

And the mach kernel has to have a small amount of code added to map that
physical space into the vmlinux server's address space, I believe, or
probably more like additional code in the vmlinux server to request it....
I'm not sure where the line is drawn... I'm still learning the
Mach/vmlinux io mapping stuff, the hard way... by coding something and
then poking around to see why it doesn't work.  :-)

Personally, I don't have any problem with requiring people to upgrade
their kernel for enhanced performance, though adding traditional ioctl
support for people who don't want to upgrade would be a nice touch.  With
the amount of kernel development happening right now, and the number of
bugs being fixed, people would be well advised to try to stay current if
they're using MkLinux anyway.  ;-)

Well, I've considered porting the Linux 2.1 framebuffer devices as
part of the current work on porting the gnumach Linux device driver
support to the OSF Mach kernel used by MkLinux.  However, the gnumach
code currently supports only block and network devices, and adding the
video support currently isn't on my personal priority list.  (Porting
MkLinux to Linux 2.1 seems higher priority...)

So, pragmatically, choice #2 still seems more feasible in the short
term.  In the long term, I agree that choice #1 would be better.

Doesn't the stuff in <asm/vc_ioctl.h> come from MkLinux?

This is indeed a very good question!

I think the most important reason is that you're integrated with XFree86 (like
all the other Linux ports), and get all its extra features for free.

Another approach would be to create a new subdirectory
xc/programs/Xserver/hw/xfree68/xpmac/, that only differs from the xfree68/fbdev
directory by the differences between the frame buffer device API and the
MkLinux graphics API. The disadvantage of this is that you still have two
server binaries, though.

I must confess that I am a bit lost among the many different versions of 
XF68_FBDev. For the one from XFree86 3.3.3, do I have to install all of 
XFree86 3.3.3, or does it work with XFree86 3.3.2 which is in linuxppc-pre-R5?
I tried several versions, and both on R4 and on pre-R5, the result was the same.
Except that some versions did not want to run on pre-R5.

I would be the first to assume that this is a problem with my configuration,
except that there were some reports by others who had the same problems,
and I am pretty sure that there is a large silent majority of linuxppc users on power Macs who never tried XF68_FBDev so far.

If XF68_FBDev is going to be the standard for everybody, one should make sure
that it works on PowerMacs, too.

The X server doesn't use any of the X11 shared libs. All it needs is libc and
libm. So if you have to correct glibc, it's supposed to work.

Geert> What about the XF68_FBDev from XFree86 3.3.3?

Hi,

I just installed Xfree86-3.3.3 and XF68_FBDev on PowerMac
8500/120 (standard Apple keyboard, 1-button mouse and
linuxpmac 2.1.125).  The situation was the same as Martin.
So, I added adb_buttons=1 in boot-file and restarted the
system.  Then it seems to me that option key itself acts
like right button.  However, there is no middle button
emulation.

Somebody in this list I can't remember (sorry) wrote that
adb_buttons=1 option enable the right option- and control-
keys to emulate mouse buttons.  Unfortunately, my standard
Apple keyboard has left option- and control- keys but does
not have right ones. :-(

Yes, MkLinux uses the VC_* ioctls.  I presume that's what you mean...

Maybe.  I'm not saying the linux server part doesn't have the support,
just that the mach kernel drivers don't, AFAIK.  :-)

Re: XF68_FBDev under MkLinux?

[Elgin Lee]

Geert--

Perhaps I misunderstand.  What ioctls are you proposing to use?
MkLinux (Linux and Mach sides combined) supports ioctls like
VC_GETMODE, VC_SETMODE, VC_INQMODE, VC_SETCMAP, and VC_GETCMAP.
However, I believe that the Mach drivers will currently only allow you
to use the one video mode (width, height, depth, etc.) in effect from
the MacOS side.  That one mode should be revealed by the video ioctls.

Would that restriction cause a problem?

These ioctls.

No problem. That's very similar to `mode "default"' with XF68_FBDev.

The framework is already in the mach kernel. In fact, there is video
initialization code for the pdm (the [6-8]100's)?? The other drivers
are only partially implemented.

status of multiprocessor support?

[Wesley Horner]

I am thinking about picking up a duel 604e/200 for Linuxppc and BeOS but I
am worried that BeOS will be the only one to see any benefit.  Has anybody
gotten linuxppc working on two processors yet.  If so what was required.

 I have an mmap and ioctl stuff patch for MkLinux at:
  ftp://ppc.linux.or.jp/pub/users/oikawa/mklinux/AccelX_interface/981017/AccelX_support.patch
that makes ioctl(, VC_GETMODE, (struct vc_mode *)&mode) be able to fill out
mode.disp_reg_address field with mmappable graphic chip's MMIO address.

Sorry, but you have to apply this patch manually because this is not
to GENERIC ## kernel but to Apple's DR3 and it contains unnecessary
code appended.
 This patch doesn't do any address alignment even if MMIO address is
not page aligned. Please fix it before use such a graphic chip.

is this a Mac or some other board? I'll be working on SMP for the Motorola
MTX in a few weeks.

Mac SMP is partially/mostly supported, AFAIK
