| * | acpi-cpufreq: Fix some x86/x86-64 acpi-cpufreq driver issuesFenghua Yu2007-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses some issues in x86/x86-64 acpi-cpufreq driver: 1. Current memory allocation for acpi_perf_data is actually open-coded alloc_percpu(). The patch defines and handles acpi_perf_data as percpu data. The code will be cleaner and easier to be maintained with this change. 2. Won't load driver in acpi_cpufreq_early_init() failure case. 3. Add __init for acpi_cpufreq_early_init().

Raising this trip-point may allow you to keep your system silent up to a higher temperature. However, it will not allow you to raise the lowest temperature trip point above the next higher trip point (if there is one). Lowering this trip point may kick in the fan sooner. Note that overriding this trip-point will disable any BIOS attempts to implement hysteresis around the lowest temperature trip point. This may result in the fan starting and stopping frequently if temperature frequently crosses C. WARNING: raising trip points above the manufacturer's defaults may cause the system to run at higher temperature and shorten its life. Signed-off-by: Len Brown <len.brown@intel.com>

They will be marked as <disabled> in /proc/acpi/thermal_zone/*/trip_points. There are two cases where this option is used: 1. Debugging a hot system crossing valid trip point. If your system fan is spinning at full speed, be sure that the vent is not clogged with dust. Many laptops have very fine thermal fins that are easily blocked. Check that the processor fan-sink is properly seated, has the proper thermal grease, and is really spinning. Check for fan related options in BIOS SETUP. Sometimes there is a performance vs quiet option. Defaults are generally the most conservative. If your fan is not spinning, yet /proc/acpi/fan/ has files in it, please file a Linux/ACPI bug. WARNING: you risk shortening the lifetime of your hardware if you use this parameter on a hot system. Note that this refers to all system components, including the disk drive. 2. Working around a cool system crossing critical trip point due to erroneous temperature reading. Try again with CONFIG_HWMON=n There is known potential for conflict between the the hwmon sub-system and the ACPI BIOS. If this fixes it, notify lm-sensors@lm-sensors.org and linux-acpi@vger.kernel.org Otherwise, file a Linux/ACPI bug, or notify just linux-acpi@vger.kernel.org.

"thermal.psv=C", where 'C' is degrees Celsius, overrides all existing passive trip points for all ACPI thermal zones. thermal.psv is checked at module load time, and in response to trip-point change events. Note that if the system does not deliver thermal zone temperature change events near the new trip-point, then it will not be noticed. To force your custom trip point to be noticed, you may need to enable polling: eg. thermal.tzp=3000 invokes polling every 5 minutes. Note that once passive thermal throttling is invoked, it has its own internal Thermal Sampling Period (_TSP), that is unrelated to _TZP.

If _TZP is 0, no polling should be used. If _TZP is non-zero, then the platform recommends that the OS poll the thermal zone at the specified rate. The minimum period is 30 seconds. The maximum period is 5 minutes. (note _TZP and thermal.tzp units are in deci-seconds, so _TZP = 300 corresponds to 30 seconds) If _TZP is not present, ACPI 3.0b recommends that the thermal zone be polled at an "OS provided default frequency". However, common industry practice is: 1. The BIOS never specifies any _TZP 2. High volume OS's from this century never poll any thermal zones Ie. The OS depends on the platform's ability to provoke thermal events when necessary, and the "OS provided default frequency" is "never":-) There is a proposal that ACPI 4.0 be updated to reflect common industry practice -- ie. no _TZP, no polling. The Linux kernel already follows this practice -- thermal zones are not polled unless _TZP is present and non-zero. But thermal zone polling is useful as a workaround for systems which have ACPI thermal control, but have an issue preventing thermal events. Indeed, some Linux distributions still set a non-zero thermal polling frequency for this reason. But rather than ask the user to write a polling frequency into all the /proc/acpi/thermal_zone/*/polling_frequency files, here we simply document and expose the already existing module parameter to do the same at system level, to simplify debugging those broken platforms. Note that thermal.tzp is a module-load time parameter only. Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the z/VM reader is already open, it can happen that after opening the Linux reader device, not the topmost file is processed. According the semantics of the Linux z/VM unit record device driver, always the topmost file has to be processed. With this fix an error is returned if that is not the case.

| * | | | [S390] vmur: reject open on z/VM reader files with status HOLDMichael Holzheu2007-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a reader file with HOLD status is at the top of the reader queue, currently all read requests will return data of the second file in the queue. But the semantics of vmur is that always the topmost file is read. With this fix -EPERM is returned on open, if the topmost reader file is in HOLD status.

| * | | | [S390] vmur: allocate single record buffers instead of one big data bufferMichael Holzheu2007-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vmur allocates one contiguous kernel buffer to copy user data when creating ccw programs for punch or printer. If big block sizes are used, under memory pressure it can happen, that we do not get memory in one chunk. Now we allocate memory for each single record to avoid high order allocations.

To make sure this is the case even if slab debugging is turned on create an own slab cache for qdio_q structures. Besides that don't use the slab allocator to allocate whole pages. Use the page allocator instead. Also fix a few memory leaks in error handling code.
