2009-01-11irq: initialize nr_irqs based on nr_cpu_idsMike Travis
Impact: Reduce memory usage. This is the second half of the changes to make the irq_desc_ptrs be variable sized based on nr_cpu_ids. This is done by adding a new "max_nr_irqs" macro to irq_vectors.h (and a dummy in irqnr.h) to return a max NR_IRQS value based on NR_CPUS or nr_cpu_ids. This necessitated moving the define of MAX_IO_APICS to a separate file (asm/apicnum.h) so it could be included without the baggage of the other asm/apicdef.h declarations. Signed-off-by: Mike Travis <travis@sgi.com>
2009-01-11irq: change references from NR_IRQS to nr_irqsMike Travis
Impact: preparation, cleanup, add KERN_INFO printk Modify references from NR_IRQS to nr_irqs as the later will become variable-sized based on nr_cpu_ids when CONFIG_SPARSE_IRQS=y. Signed-off-by: Mike Travis <travis@sgi.com>
2009-01-11x86: reduce stack usage in init_intel_cacheinfoMike Travis
Impact: reduce stack usage. init_intel_cacheinfo() does not use the cpumask so define a subset of struct _cpuid4_info (_cpuid4_info_regs) that can be used instead. Signed-off-by: Mike Travis <travis@sgi.com>
2009-01-11x86: cleanup remaining cpumask_t code in mce_amd_64.cMike Travis
Impact: Reduce memory usage, use new cpumask API. Use cpumask_var_t for 'cpus' cpumask in struct threshold_bank and update remaining old cpumask_t functions to new cpumask API. Signed-off-by: Mike Travis <travis@sgi.com>
2009-01-11SGI UV cpumask: use static temp cpumask in flush_tlbMike Travis
Impact: Improve tlb flush performance for UV Calling alloc_cpumask_var a zillion times a second does affect performance. Replace with static cpumask. Note: when CONFIG_X86_UV is defined, this extra PER_CPU memory will be optimized out for non-UV configs as is_uv_system() will then return a constant 0. Signed-off-by: Mike Travis <travis@sgi.com>
2009-01-11x86: change flush_tlb_others to take a const struct cpumaskRusty Russell
Impact: reduce stack usage, use new cpumask API. This is made a little more tricky by uv_flush_tlb_others which actually alters its argument, for an IPI to be sent to the remaining cpus in the mask. I solve this by allocating a cpumask_var_t for this case and falling back to IPI should this fail. To eliminate temporaries in the caller, all flush_tlb_others implementations now do the this-cpu-elimination step themselves. Note also the curious "cpus_or(f->flush_cpumask, cpumask, f->flush_cpumask)" which has been there since pre-git and yet f->flush_cpumask is always zero at this point.

2009-01-11cpumask: update irq_desc to use cpumask_var_tMike Travis
Impact: reduce memory usage, use new cpumask API. Replace the affinity and pending_masks with cpumask_var_t's. This adds to the significant size reduction done with the SPARSE_IRQS changes. The added functions (init_alloc_desc_masks & init_copy_desc_masks) are in the include file so they can be inlined (and optimized out for the !CONFIG_CPUMASKS_OFFSTACK case.) [Naming chosen to be consistent with the other init*irq functions, as well as the backwards arg declaration of "from, to" instead of the more common "to, from" standard.] Includes a slight change to the declaration of struct irq_desc to embed the pending_mask within ifdef(CONFIG_SMP) to be consistent with other references, and some small changes to Xen.

2009-01-11MIPS: Alchemy: new userspace suspend interface for development boards.Manuel Lauss
Replace the current sysctl-based suspend interface with a new sysfs- based one which also uses the Linux-2.6 suspend model. To configure wakeup sources, a subtree for the demoboards is created under /sys/power/db1x: sys/ `-- power `-- db1x |-- gpio0 |-- gpio1 |-- gpio2 |-- gpio3 |-- gpio4 |-- gpio5 |-- gpio6 |-- gpio7 |-- timer |-- timer_timeout |-- wakemsk `-- wakesrc The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2 bits of the SYS_WAKEMSK (wakeup source enable) register. Writing '1' enables a wakesource, 0 disables it. The 'timer_timeout' node holds the timeout in seconds after which the TOYMATCH2 event should wake the system. The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex), the 'wakemsk' node can be used to get/set the wakeup mask directly. For example, to have the timer wake the system after 10 seconds of sleep, the following must be done in userspace: echo 10 > /sys/power/db1x/timer_timeout echo 1 > /sys/power/db1x/timer echo mem > /sys/power/sleep This patch also removes the homebrew CPU frequency switching code. I don't understand how it could have ever worked reliably; it does not communicate the clock changes to peripheral devices other than uarts.

2009-01-11MIPS: Alchemy: Fix up PM code on Au1550/Au1200Manuel Lauss
Au1550/Au1200 have a different memory controller which requires additi- onal code to properly put memory to sleep (code taken from AMD/RMI's Linux-2.6.11 source package).

2009-01-11MIPS: Alchemy: move calc_clock function.Manuel Lauss

2009-01-11MIPS: Alchemy: RTC counter clocksource / clockevent support.Manuel Lauss
Add support for the 32 kHz counter1 (RTC) as clocksource / clockevent device. As a nice side effect, this also enables use of the 'wait' instruction for runtime idle power savings. If the counters aren't enabled/working properly, fall back on the cp0 counter clock code. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-01-11MIPS: make cp0 counter clocksource/event usable as fallback.Manuel Lauss
The current mips clock build infrastructure lets a system only use either the MIPS cp0 counter or a SoC specific timer as a clocksource / clockevent device. This patch renames the core cp0 counter clocksource / clockevent functions from mips_* to r4k_* and updates the wrappers in asm-mips/time.h to call these renamed functions instead. Chips which can detect whether it is safe to use a chip-specific timer can now fall back on the cp0 counter if necessary and possible (e.g. Alchemy with a follow-on patch). Existing behaviour is not changed in any way. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-01-11MIPS: Alchemy: remove cpu_table.Manuel Lauss

2009-01-11MIPS: Alchemy: update core interrupt code.Manuel Lauss
This patch attempts to modernize core Alchemy interrupt handling code. - add irq_chips for irq controllers instead of irq type, - add a set_type() hook to change irq trigger type during runtime, - add a set_wake() hook to control GPIO0..7 based wakeup, - use linux' IRQF_TRIGGER_ constants instead of homebrew ones, - enable GENERIC_HARDIRQS_NO__DO_IRQ. - simplify plat_irq_dispatch - merge au1xxx_irqmap into irq.c file, the only place where its contents are referenced. - board_init_irq() is now mandatory for every board; use it to register the remaining (gpio-based) interrupt sources; update all boards accordingly.
