2007-02-22[CPUFREQ] constify cpufreq_driver where possible.Dave Jones12-13/+13

2007-02-20rdmsr_on_cpu, wrmsr_on_cpuAlexey Dobriyan4-1/+74
There was OpenVZ specific bug rendering some cpufreq drivers unusable on SMP. In short, when cpufreq code thinks it confined itself to needed cpu by means of set_cpus_allowed() to execute rdmsr, some "virtual cpu" feature can migrate process to anywhere. This triggers bugons and does wrong things in general. This got fixed by introducing rdmsr_on_cpu and wrmsr_on_cpu executing rdmsr and wrmsr on given physical cpu by means of smp_call_function_single(). Dave Jones mentioned cpufreq might be not only user of rdmsr_on_cpu() and wrmsr_on_cpu(), so I'm putting them into arch/{i386,x86_64}/lib/ .

2007-02-14[CPUFREQ] Longhaul - Redo Longhaul ver. 2Rafał Bilski1-22/+31
Start using v2 version of Longhaul when available. It provides voltage scaling and can use ACPI C3 state. That's curious. CPU will not change frequency on ACPI C3 when v1 is in use, but it will when v2 is used. Driver will return max frequency all the time if this isn't true for all processors. There is strange thing with mobile voltage. Looks like only Nehemiah (C3-M) supports it. Earlier processors have different mobile VRM (in docs), but I can't find any which is using it. Looks like all are using VRM 8.5. So fail for non Nehemiah with mobile VRM. Signed-off-by: Rafal Bilski <rafalbilski@interia.pl> Signed-off-by: Dave Jones <davej@redhat.com>

2007-02-10[CPUFREQ] Longhaul - Separate frequency and voltage transitionRafał Bilski1-16/+93
This change should make Longhaul more compatible with both ver. 2 and Powersaver processors. Voltage transitions will be done before or after frequency transition. That depends on direction of change. I don't know how to force conservative governor when voltage scaling is enabled, so there is only a warning for user. Minimal voltage is calculated in different way now because in this way more power is saved at lower multipliers.

2007-02-10[CPUFREQ] Enhanced PowerSaver driverRafał Bilski3-0/+344
This is driver for Enhanced Powersaver which is present in VIA C7 processors. Beta tested by Jorgen (jorgen (at) greven dot dk). Thanks! Based on documentation provided by Dave Jones (Thanks!) and C7 Eden datasheet available from www.via.com.tw. Looks like all these C7 Eden CPU's don't have P-states in BIOS. I know that 2 p-states is low, but Jorgen finds it usefull anyway because board is passive cooled. There are 3 different types of C7 processors (called brands): 0. C7-M - these processors can set any maultiplier between min and max, any voltage between min and max. 1. C7 - only min and max states are supported. Voltage is different for min and max states. 2. Eden - only min and max states are supported. Looks like this brand can only change multiplier. Voltage seems to be the same for min and max frequency.

2007-02-09[AVR32] Add PIOE device and reserve SDRAM pinsHaavard Skinnemoen2-0/+33
The PIOE device was left out before because it muxes SDRAM pins (and is therefore a bit dangerous to mess with) and because no existing drivers had any use for it. It is needed for CompactFlash, however, and now that we have a way to protect the SDRAM pins, it can be safely added. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2007-02-09[AVR32] ext int fixesDavid Brownell1-19/+17
Bugfixes for external irq handler set_irq_type(): - If set_irq_type() can't set the type, don't change anything! - It's not OK to change the flow handler as part of set_irq_type(), among other issues that violates spinlock rules. Instead, we can call the relevant handler when we demux the external interrupts. - The external irq demux has no need to grab the spinlock. And in fact grabbing it that way was wrong, since that code might be pre-empted by an irq at a different priority level, and that code might then have tried to grab that spinlock...
