[PATCH] Fix ppc64 smu driver locking

2005-09-29T22:42:58+00:00

The SMU driver has a small mistake in the locking of the interrupt code,
if polled access and interrupt access race, interrupt may take a lock
and return without releasing it. This fixes it. With that patch, the
driver is rock solid with my experimental thermal control (which bangs
it pretty hard) racing with real time clock and cpufreq handling.

[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] swsusp: switch pm_message_t to struct

2005-09-05T07:06:16+00:00

This adds type-checking to pm_message_t, so that people can't confuse it
with int or u32.  It also allows us to fix "disk yoyo" during suspend (disk
spinning down/up/down).

[We've tried that before; since that cpufreq problems were fixed and I've
tried make allyes config and fixed resulting damage.]

[PATCH] swsusp: fix remaining u32 vs. pm_message_t confusion

2005-09-05T07:06:15+00:00

Fix remaining bits of u32 vs.  pm_message confusion.  Should not break
anything.

[PATCH] ppc64: hide CONFIG_ADB

2005-07-27T23:25:57+00:00

This bites me all day when I use our default config for ppc64.  We use a
patch to fix the compile errors and provide the CONFIG_MAC_EMUMOUSEBTN
functionality (which is behind CONFIG_INPUT_ADBHID).  But Benh doesnt like
it.

http://ozlabs.org/pipermail/linuxppc64-dev/2005-March/003423.html

Just hide all the ADB parts from via-pmu on ppc64 instead.

[PATCH] openfirmware: implement hotplug for macio devices

2005-07-06T19:55:20+00:00

This adds the hotplug routine for generating hotplug events when devices
are seen on the macio bus.  It uses the attributed created by the sysfs
nodes to generate the hotplug environment vars for userspace.

Since the characters allowed inside the 'compatible' field are NUL
terminated, they are exported as individual OF_COMPATIBLE_# variables,
with OF_COMPATIBLE_N maintaining a count of how many there are.

In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied.  Those patches are
available at:

[PATCH] openfirmware: add sysfs nodes for open firmware devices

2005-07-06T19:55:20+00:00

This adds sysfs nodes that the hotplug userspace can use to load the
appropriate modules.

In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied.  Those patches are
available at:

 ftp://ftp.suse.com/pub/people/jeffm/linux/macio-hotplug/

Changes: The previous versions were built on 2.6.12. 2.6.13-rcX introduced
         a device_attribute parameter to the show functions. Since that
         parameter was treated as the output buffer, memory corruption would
         result, causing Oopsen very quickly.

[PATCH] openfirmware: generate device table for userspace

2005-07-06T19:55:20+00:00

This converts the usage of struct of_match to struct of_device_id,
similar to pci_device_id.  This allows a device table to be generated,
which can be parsed by depmod(8) to generate a map file for module
loading.

[PATCH] ppc32: Remove CONFIG_PMAC_PBOOK

2005-06-27T22:11:43+00:00

This patch removes CONFIG_PMAC_PBOOK (PowerBook support).  This is now
split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some
powerbooks have, CONFIG_PM for power management related code, and just left
out of any CONFIG_* option for some generally useful stuff that can be used
on non-laptops as well.
