* locking: Convert __raw_spin* functions to arch_spin*Thomas Gleixner2009-12-141-4/+4

* locking: Convert raw_spinlock to arch_spinlockThomas Gleixner2009-12-141-1/+1
| | | | | | | | | | | | | | | | | | | The raw_spin* namespace was taken by lockdep for the architecture specific implementations. raw_spin_* would be the ideal name space for the spinlocks which are not converted to sleeping locks in preempt-rt. Linus suggested to convert the raw_ to arch_ locks and cleanup the name space instead of using an artifical name like core_spin, atomic_spin or whatever No functional change.

* powerpc: Change archdata dma_data to a unionBecky Bruce2009-09-241-1/+1
| | | | | | | | | | Sometimes this is used to hold a simple offset, and sometimes it is used to hold a pointer. This patch changes it to a union containing void * and dma_addr_t. get/set accessors are also provided, because it was getting a bit ugly to get to the actual data.

| | | | | | | | | | | | | | | | | | | | | | CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | The logic that checks to see if a machine check is caused by an NMI will always match when NMI hasn't been initialized, since the mpic routine will return NO_IRQ (and that's what the nmi_virq value is as well). Signed-off-by: Olof Johansson <olof@lixom.net>
* | [POWERPC] pasemi: Distribute interrupts evenly across cpusOlof Johansson2007-12-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default the OpenPIC on PWRficient will bias to one core (since that will improve changes of the other core being able to stay idle/powered down). However, this conflicts with most irq load balancing schemes, since setting an interrupt to be delivered to either core doesn't really result in the load being shared. It also doesn't work well with the soft irq disable feature of PPC, since EE will stay on until the first interrupt is taken while soft disabled. Set the gconf0 config bit that enables even distribution of interrupts among the two cores. Signed-off-by: Olof Johansson <olof@lixom.net>
* | [POWERPC] pasemi: Implement NMI supportOlof Johansson2007-12-281-3/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PWRficient-based boards have a NMI button that's wired up to a GPIO as interrupt source. By configuring the openpic accordingly, these get delivered as a machine check with high priority, instead of as an external interrupt. The device tree contains a property "nmi-source" in the openpic node for these systems, and it's the (hwirq) source for the input. Also, for these interrupts, the IACK is read from another register than the regular (MCACK instead), but they are EOI'd as usual. So implement said function for the mpic driver. Finally, move a couple of external function defines to include/ instead of local under sysdev. Being able to mask/unmask and eoi directly saves us from setting up a dummy irq handler that will never be called. Signed-off-by: Olof Johansson <olof@lixom.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | Maple and pasemi both require PCI as does CONFIG_OF_PLATFORM_PCI. The default setting of CONFIG_ISA_DMA_API is set to match the protection around the relevant routines in asm/dma.h. I also had to remove the PMAC platform from the combined build. The precis is that to build a 64 bit kernel with no PCI, you can only include pSeries and iSeries.

* | [POWERPC] pasemi: Implement MSI supportOlof Johansson2007-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement MSI support for PA Semi PWRficient platforms. MSI is done through a special range of sources on the openpic controller, and they're unfortunately breaking the usual concepts of how sources are programmed: * The source is calculated as 512 + the value written into the MSI register * The vector for this source is added to the source and reported through IACK This means that for simplicity, it makes much more sense to just set the vector to 0 for the source, since that's really the vector we expect to see from IACK. Also, the affinity/priority registers will affect 16 sources at a time. To avoid most (simple) users from being limited by this, allocate 16 sources per device but use only one. This means that there's a total of 32 sources. If we get usage scenarions that need more sources, the allocator should probably be revised to take an alignment argument and size, not just do natural alignment. Finally, since I'm already touching the MPIC names on pasemi, rename the base one from the somewhat odd " PAS-OPIC " to "PASEMI-OPIC".

This uses this property instead of assuming 64. If no property is found, we assume 64 entries as before. This soft patches the SLB handler, so it shouldn't change performance at all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the PWRficient cpus are entered into powersavings states, the astate is automatically dropped down to 0. While we still restore it when we come out of idle, it can still cause some weird effects with respect to performance (especially since it takes a while to ramp up to higher astates). So, to avoid this, don't enter power savings when the cpufreq driver (or user) has set higher astates than 0. The restore is still required, since there's a chance the astate has been raised from the other cpu while the idling one was asleep. Signed-off-by: Olof Johansson <olof@lixom.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We no longer initialise the name and owner fields of the of_platform_driver, but use the fields of the embedded device_driver's name field instead.

| * | [POWERPC] Add workaround for MPICs with broken register readsOlof Johansson2007-09-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some versions of PWRficient 1682M have an interrupt controller in which the first register in each pair for interrupt sources doesn't always read with the right polarity/sense values. To work around this, keep a software copy of the register instead. Since it's not modified from the mpic itself, it's a feasible solution. Still, keep it under a config option to avoid wasting memory on other platforms. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>
