* [CPUFREQ] speedstep-centrino should ignore upper performance control bitsGary Hade2006-12-12
| | | | | | | | | | | | | | On some systems there could be bits set in the upper half of the control value provided by the _PSS object. These bits are only relevant for cpufreq drivers that use IO ports which are not currently supported by the speedstep-centrino driver. The current MSR oriented code assumes that upper bits are not set and thus fails to work correctly when they are. e.g. the control and status value equality check failed on the IBM x3650 even though the ACPI spec allows inequality.

* [CPUFREQ] Workaround for BIOS bug in software coordination of frequencyVenkatesh Pallipadi2006-09-05
| | | | | | | | | | | | | | | | Some buggy BIOSes do a "software any" kind of coordination without telling about it to OS. So, when OS sets frequency on one CPU on these platforms, it will also impact all the other logical CPUs that are in the same power domain. Attached patch is a workaround for those buggy BIOSes. Patch should be a noop on the normal non-buggy platforms.

I get a steady stream of mail which I don't really do anything useful with; the cpufreq list seems like a better destination, unless someone wants to get the mail directly. Also clean up a couple of ancient comments which don't really apply anymore (as far as I know, nobody has ever damaged a CPU with this driver).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux invokes the AML _PDC method (Processor Driver Capabilities) to tell the BIOS what features it can handle. While the ACPI spec says nothing about the OS invoking _PDC multiple times, doing so with changing bits seems to hopelessly confuse the BIOS on multiple platforms up to and including crashing the system. Factor out the _PDC invocation so Linux invokes it only once. http://bugzilla.kernel.org/show_bug.cgi?id=5483 Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

* | [PATCH] fix missing includesTim Schmielau2005-10-30
|/ | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [CPUFREQ] speedstep-centrino: skip extract_clock logic for acpi based centrinoVenkatesh Pallipadi2005-09-01
| | | | | | | | | | | | | | | | | | speedstep_centrino.c:extract_clock() assumes the bus speed of 100MHz, which is not true with latest laptops. Due to this assumption and due to the encoded frequency check during initialization, speedstep-centrino driver fails even on systems that has proper ACPI information to do the P-state transition. The change below moves the centrino-speedstep detection to be used only when table based P-state transition is done. For ACPI based P-state transition, we skip the centrino_cpu identification, and as a result we don't use the bus speed assumption in extract_clock. This change makes speedstep-centrino work on Pentium-M based systems, which have more than 100MHz bus speed.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
