2007-06-14[POWERPC] Fix per-cpu allocation on oldworld SMP powermacsPaul Mackerras
The per-cpu area(a) for the secondary CPU(s) isn't getting allocated on old SMP powermacs that don't have the secondary CPU(s) listed in the device tree, as per-cpu areas are now only allocated for CPUs in the cpu_possible_map, and we aren't setting the bits for the secondary CPU(s) until smp_prepare_cpus(), which is after per-cpu allocation. Therefore this sets the bits for CPUs 1..3 in cpu_possible_map in pmac_setup_arch, so they get per-cpu data allocated. Signed-off-by: Paul Mackerras <paulus@samba.org>

This allows "hotplugging" of CPUs on G5 machines. CPUs that are disabled are put into an idle loop with the decrementer frequency set to minimum. To wake them up again we kick them just like when bringing them up. To stop those CPUs from messing with any global state we stop them from entering the timer interrupt.

2007-05-02[POWERPC] Fix suspend states againJohannes Berg
In commit 0fba3a1f39f8b0a50b56c8b068fa52131cbc84c2 (a very long time ago, May 2006), I fixed a bug that caused powermacs to crash when you tried entering standby/mem suspend states. As I'm now getting more familiar with the suspend code I notice a few more things: 1. we previously misunderstood what pm_ops is for, it isn't supposed to be for doing platform dependent suspend/resume stuff that needs to be done for suspend to disk (as we currently try to use it!), it is instead for entering platform dependent suspend states ("standby", "mem"). 2. due to the first point, we never properly save FPU and altivec states when suspending to disk. It probably hasn't hurt yet because the process that writes the "disk" to /sys/power/state uses neither and its context is used. This patch addresses these points as follows: 1. remove all pm_ops from powermac, powermac suspend to ram isn't currently usable via /sys/power/state but is done via the PMU instead. 2. move the code responsible for storing FPU/altivec state into save_processor_state and the set_context() call to restore_processor_state. 3. add a call to kernel_enable_spe() It may look like there is some code removal missing but that is actually because the new suspend.h file overrides the ppc/suspend.h one which was previously used.

2006-12-04[POWERPC] Souped-up of_platform_device supportBenjamin Herrenschmidt
This patch first splits of_device.c and of_platform.c, the later containing the bits relative to of_platform_device's. On the "breaks" side of things, drivers uisng of_platform_device(s) need to include asm/of_platform.h now and of_(un)register_driver is now of_(un)register_platform_driver. In addition to a few utility functions to locate of_platform_device(s), the main new addition is of_platform_bus_probe() which allows the platform code to trigger an automatic creation of of_platform_devices for a whole tree of devices. The function acts based on the type of the various "parent" devices encountered from a provided root, using either a default known list of bus types that can be "probed" or a passed-in list. It will only register devices on busses matching that list, which mean that typically, it will not register PCI devices, as expected (since they will be picked up by the PCI layer). This will be used by Cell platforms using 4xx-type IOs in the Axon bridge and can be used by any embedded-type device as well.

2006-12-04[POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt
This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

2006-07-03[POWERPC] Add new interrupt mapping core and change platforms to use itBenjamin Herrenschmidt
This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.

This patch adds the .valid callback to pm_ops on PowerMac so that only the suspend to disk state can be entered. Note that just returning 0 would suffice since the upper layers don't pass PM_SUSPEND_DISK down, but we handle it there regardless just in case that changes.

We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants.

2006-01-09[PATCH] 2/5 powerpc: Rework PowerMac i2c part 2Benjamin Herrenschmidt
This is the continuation of the previous patch. This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

2006-01-09[PATCH] powerpc: Merge kexecMichael Ellerman
This patch merges, to some extent, the PPC32 and PPC64 kexec implementations. We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions. The current PPC64 implementation becomes the "default" implementation for PPC64 which platforms can select if they need no special treatment. I've added these default callbacks to pseries/maple/cell/powermac, this means iSeries no longer supports kexec - but it never worked anyway. I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with PPC64. Judging by the comments it might be better named machine_kexec_non_of, or something, but at the moment it's the only implementation for PPC32 so it's the "default". Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we already have in setup-common.c on powerpc. All this does is call ppc_md.nvram_sync, which only powermac implements, so instead make machine_shutdown a ppc_md member and have it call core99_nvram_sync directly on powermac. I've also stuck relocate_kernel.S into misc_32.S for powerpc. Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on P5 LPAR and successfully kexec'ed.

This makes platform code use the smp_ops variable directly instead of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments from the *_message_pass() functions, and removes the call to the never-implemented smp_ops->space_timers() function.
