[PATCH] ppc: Fix timekeeping with HZ=250 on some Mac models

2005-10-05T14:33:42+00:00

Older Macs which uses the VIA chip timers to calibrate the timebase used
some code that wouldn't work if HZ wasn't divisible by 100...

This fixes it at least for 250.  Not totally perfect but should be
enough for now (so it at least works with the default value which is now
250).

There is still a potential issue with the core using CLOCK_TICK_RATE to
maintain xtime and CLOCK_TICK_RATE value on ppc32 is pure crap, but that
is a different problem, this patch at least brings us back to our
previous situation.

[PATCH] ppc32: Add new iBook 12" to PowerMac models table

2005-10-02T00:01:48+00:00

This adds the new iBook G4 (manufactured after July 2005) to the
PowerMac models table.  The model name (PowerBook6,7) is taken from a
12" iBook, I don't know if it also matches the 14" version.  The patch
applies to a vanilla 2.6.13.2 kernel.

[PATCH] pmac: fix cpufreq for old tipb 550Mhz

2005-10-01T00:20:20+00:00

The old 550Mhz titanium powerbook can switch to a lower frequency
(500Mhz). A user has been repeately reporting overtemp conditions on his
machine at high speed so this simple patch adds support to PowerMac
cpufreq for this machine. The difference in frequency isn't big but seem
enough to fix that user's problems. The patch has been around for some
time now and doesn't seem to cause any problem, so I suppose it could go
in now.

[PATCH] ppc64: SMU driver update & i2c support

2005-09-23T05:17:35+00:00

The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5.  It drives things like fans, i2c busses, real time
clock, etc...

The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously.  This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors.  This driver is a basic block
for upcoming work on thermal control for those machines, among others.

[PATCH] ppc32: support hotplug cpu on powermacs

2005-09-10T17:15:11+00:00

This allows cpus to be off-lined on 32-bit SMP powermacs.  When a cpu
is off-lined, it is put into sleep mode with interrupts disabled.  It
can be on-lined again by asserting its soft-reset pin, which is
connected to a GPIO pin.

With this I can off-line the second cpu in my dual G4 powermac, which
means that I can then suspend the machine (the suspend/resume code
refuses to suspend if more than one cpu is online, and making it cope
with multiple cpus is surprisingly messy).

[PATCH] more SPIN_LOCK_UNLOCKED -> DEFINE_SPINLOCK conversions

2005-09-09T21:03:48+00:00

This converts the final 20 DEFINE_SPINLOCK holdouts.  (another 580 places
are already using DEFINE_SPINLOCK).  Build tested on x86.

[PATCH] ppc32: Kill PVR_440* defines

2005-09-09T20:57:29+00:00

The following patch changes the usages of PVR_440* into strcmp's with the
cpu_name field, and removes the defines altogether.  The Ebony portion was
briefly tested long ago.  One benefit of moving from PVR-tests to string
tests in general is that not all CPUs can be on and be able to do this type
of comparison.

thread.
