* [PATCH 03/10] Migrate Xilinx Vertex support from the OCP bus to the platfom bus.
From: Grant C. Likely @ 2006-01-14 9:48 UTC (permalink / raw)
To: linuxppc-embedded, mporter, glikely
This patch only deals with the serial port definitions as there is no
support for any other xilinx IP cores in the kernel tree at the moment.
Board specific configuration moved out of virtex.[ch] and into the
xparameters.h wrapper.
Board specific XPAR values now get bound to common defines with a 'VIRTEX_'
prefix. That way, xparameters_*.h files may be vastly different, but they
can be wired up to use the same infrastructure.
This also prepares for the transition to the flattened device tree model.
When the bootloader provides a device tree generated from an xparameters.h
files, the kernel will no longer need xparameters/*. The platform bus will
get populated with data from the device tree, and the device drivers will
be automatically connected to the devices. Only the bootloader (or
ppcboot) will need xparameters directly.

* [PATCH 02/10] Make Virtex-II Pro support generic for all Virtex devices
From: Grant C. Likely @ 2006-01-14 9:48 UTC (permalink / raw)
To: linuxppc-embedded, mporter, glikely
The PPC405 hard core is used in both the Virtex-II Pro and Virtex 4 FX
FPGAs. This patch cleans up the Virtex naming convention to reflect more
than just the Virtex-II Pro.
Rename files virtex-ii_pro.[ch] to virtex.[ch]
Rename config value VIRTEX_II_PRO to XILINX_VIRTEX

* [PATCH 01/10] Move xparameters.h into xilinx virtex device specific path
From: Grant C. Likely @ 2006-01-14 9:47 UTC (permalink / raw)
To: linuxppc-embedded, mporter, glikely
xparameters should not be needed by anything but virtex platform code.
Move it from include/asm-ppc/ to platforms/4xx/xparameters/
This is preparing for work to remove xparameters from the dependancy tree
for most c files. xparam changes should not cause a recompile of the world.
Instead, drivers should get device info from the platform bus (populated
by the boot code)

* [PATCH] Remove powermac support from ARCH=ppc
From: Paul Mackerras @ 2006-01-14 11:28 UTC (permalink / raw)
To: linuxppc-dev
This patch makes it possible to build kernels for PReP and/or CHRP
with ARCH=ppc by removing the (non-building) powermac support.
It's now also possible to select PReP and CHRP independently.
Powermac users should now build with ARCH=powerpc instead of
ARCH=ppc.
This patch doesn't actually remove all the powermac files under
arch/ppc, but they could go.
This means, BTW, that it will no longer be possible to build 32-bit
kernels for Apple G5 machines. Also, miboot users (are there any
still?) are out of luck until I move the miboot stuff over to
arch/powerpc/boot.

Can we please make arch/powerpc the defaul for native builds with uname
== ppc now that all interesting workstation class machines are supported
better by arch/powerpc? Else this patch will be rather painfull for
those building their own kernels.

Nice! Overall I like this. It removes some of the kexec limitations of
having to play with platform numbers when booting a newer kernel that
detects platforms differently (or renumbered) too.
I do have a couple of comments on the implementation:
I got complaints when I did this for cpu features, where I first used
a cpu_has_feature(<x>) syntax instead of cpu_has_feature(CPU_FTR_<x>).
I think I agree with some of the reasoning for that too: someone searching
for "powermac" when looking for the "machine_is(powermac)" logic won't
find it.
Because of this, I suggest keeping the mach_ part in the syntax, i.e,
to use:
machine_is(mach_powermac) instead, and not do preprocessor mangling of
the label name. The same would go for define_machine().
It would seem to make some sense to keep the platform types looking
like defines (i.e. MACH_POWERMAC instead of mach_powermac) to keep it
consistent with the CPU and firmware feature testing, but the way it's
implemented that doesn't make much sense. That's a bit of a shame.
In the probe loop, ppc_md is copied over for each probe, that seems
wasteful. Shouldn't the probe routines use and modify their own
machdep_calls instead of ppc_md, so the copying can be done only once,
after a match is found?

Besides the specific comments below, you have long lines in some
places. Can you break them at 78-80 columns? I know it's awkward when
a function name is 30 characters, but still.

Maybe a primitive for iterating over compatible nodes would be useful in

If you have two completely separate exit paths for error, and two
separate loops for setup, shouldn't the setup for the two cases be in
separate functions in the first place?
That way, there's no need to prefix the unreg and err exit labels
either.

If nothing else, miboot is used to make install floppies for oldworld
boxes for the Debian installer. I doubt very many people are using it
for normal boot, but this is the simplest way to boot from a floppy
disk on oldworld models.

Any reason not to remove CHRP too ?

OK, we can do that in a second step.

32 bits kernel on g5 were unuspported for ages and I announced the death
of that support long enough in advance. miboot works with plain vmlinux,
the only thing those miboot images are useful for is if you need a
compressed image due to lack of space and/or if you need an embedded
initrd. Hopefully, that should be trivial to add back though.

I'm not sure about these ... I'm definitely not fan of going uppercase (and
it makes no sense vs. the implementation as it's not macros). I also don't
get your problem with grep... the "mach_" construct is totally invisible,
so people wouldn't grep for it, but for "powermac" alone.
Or do you mean a grep on "powermac" might return too many things unrelated ?
It should be easy enough in this case to grep for machine_is(powermac) instead
then, after all, that's the only possible use...

I changed that from the old way indeed to allow the probe() function to
override things in ppc_md.
> Shouldn't the probe routines use and modify their own

I don't like modifying their own machdep calls because the name of the
structure is hidden. In general, I prefer that things continue to only
access ppc_md. and not their own machine structure that goes away. That
means that the code "patching" it can be moved away etc... without
special case instead of having a special case in probe() that has to
reference the machine specific copy...
I doubt the memcpy per machine at boot will cause any kind of
significant performance issue ...

IMHO, this is not needed because _everybody_ who is working
with these chips know what IMMR means. And there cannot be _any_
confusion about it. Let's not add useless comments.
We don't add comments describing what MMU, PTE, PCI and IOMMU means,
do we? Any chip specific code has tons of strange abbreviations
which might be puzzling for anybody who isn't familiar with this chip
but are quite clear for anybody who are.

Yeah, that's what I meant with doesn't make sense in this case. I was
just thinking out loud.

One drawback is that source navigation tools like tags and cscope probably
won't find it, and the base strings are quite generic (powermac, cbe/cell,
etc). A stringbased grep will, sure.

Ok.

Yeah, that's why I said it seemed wasteful, not that it'd be a
performance issue.

* [PATCH 001/001] subsystem: Themperature monitoring for ibook 2.2
From: Cedric Pradalier @ 2006-01-15 1:43 UTC (permalink / raw)
To: linuxppc-dev
From: Cedric Pradalier <cedric.pradalier@free.fr>
This driver provides some thermostat monitoring for ibook2,
equipped with a adm103x fan control chip. It also provides
and sysfs access to the adm103x fan control parameters. For
instance
#cat /sys/device/temperature/info?
T:51*C S:56*C R:10*C <-- sensor 0
T:48*C S:76*C R:10*C <-- sensor 1
#echo "56 10" > /sys/device/temperature/info0
make the fan starts at 56 degrees and accelerate
progressively till max at 66 degrees (56 + 10), on the
sensor 0.
The drivers also provides a ioctl access to the fan
parameters. This can be enabled/disabled at compile time.
major/minor number are 63 200, in the experimental range.

+Therm ADM103X Version 1.2.3
+--------------------------------------------------------------
+Authors...: Cedric Pradalier (cedric.pradalier@free.fr)
+
+
+Description
+--------------------------------------------------------------
+ This driver provides some thermostat monitoring for ibook2, equipped
+ with a adm1030 or adm1031 fan control chip. It also provides a sysfs
+ access to the adm103x fan control parameters. For instance
+ * #cat /sys/device/temperature/info?
+ * T:51*C S:56*C R:10*C <-- sensor 0
+ * T:48*C S:76*C R:10*C <-- sensor 1
+ * #echo "56 10" > /sys/device/temperature/info0
+ make the fan starts at 56 degrees and accelerate progressively till max
+ at 66 degrees (56 + 10), on the sensor 0.
+
+ Reading /sys/device/temperatures/minpwm0 shows the minimum speed of the fan.
+ Writing an integer value between 0 and 100 set this value. Low speed make
+ lower noise, but high speed lower temperature faster... Default is 33%.
+ * #echo "45" > /sys/device/temperature/minpwm0
+
+ You can also access the driver with ioctl commands. You need to include
+ /usr/include/linux/therm_adm103x.h in sources. Then, nearly all commands
+ expect a struct IOC_Adm103x argument.
+
+ typedef struct _IOC_Adm103x_ {
+ unsigned char id; /* sensor or fan id */
+ unsigned char mintemp; /* fan starting temp (deg)*/
+ unsigned char rangetemp; /* fan speeding range (deg)*/
+ unsigned char minpwm; /* min fan speed (percent)*/
+ signed long int millitemp; /* current temp (millideg)*/
+ unsigned char hysteresis;/* current histeresis (deg)*/
+ unsigned char reg; /* accessed register */
+ unsigned char value; /* value get/set into reg */
+ } IOC_Adm103x;
+
+ Nine commands are available :
+

I just did a "git fetch -f powerpc" where my .git/remotes/powerpc points
at the powerpc.git tree on kernel.org.

The powerpc.git tree is now identical to Linus' tree as of a day or so
ago. There are several ways you can reset your tree:
- make a fresh clone of Linus' tree, and make its .git/remotes/powerpc
point at the powerpc.git tree on kernel.org, or
- do "git fetch -f powerpc" (substitute whatever remote name you use
for the powerpc.git tree) (according to Stephen Rothwell), or
- do a pull as you would normally do, then throw away the merge and
the extra objects by doing:
git reset --hard FETCH_HEAD
git prune
- or you can delete the local tree and do a fresh clone.
I will start putting stuff in powerpc.git in the next day or so.
Paul.

I haven't been exposed much yet to embedded 32-bit PPC, I thought at
first that it was something chip-specific, not an architected feature
common across the families. I agree, it doesn't really need further
explanation in this case.

To be clear its a system level architecture feature on Freescale
SOCs. It goes by a few different names (immrbar, ccsrbar, eumbar),
but the purpose is the same.
