* 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().

* Introduce CONFIG_SUSPEND for suspend-to-Ram and standbyRafael J. Wysocki2007-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | Introduce CONFIG_SUSPEND representing the ability to enter system sleep states, such as the ACPI S3 state, and allow the user to choose SUSPEND and HIBERNATION independently of each other. Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has been chosen and the kernel is intended for SMP systems. Also, introduce CONFIG_PM_SLEEP which is automatically selected if CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the code needed for both suspend and hibernation. The top-level power management headers and the ACPI code related to suspend and hibernation are modified to use the new definitions (the changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce the number of ifdefs). There are many other files in which CONFIG_PM can be replaced with CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in the future. Signed-off-by: Rafael J.

* / | x86_64: fake pxm-to-node mapping for fake numaDavid Rientjes2007-07-21
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For NUMA emulation, our SLIT should represent the true NUMA topology of the system but our proximity domain to node ID mapping needs to reflect the emulated state. When NUMA emulation has successfully setup fake nodes on the system, a new function, acpi_fake_nodes() is called. This function determines the proximity domain (_PXM) for each true node found on the system. It then finds which emulated nodes have been allocated on this true node as determined by its starting address. The node ID to PXM mapping is changed so that each fake node ID points to the PXM of the true node that it is located on. If the machine failed to register a SLIT, then we assume there is no special requirement for emulated node affinity so we use the default LOCAL_DISTANCE, which is newly exported to this code, as our measurement if the emulated nodes appear in the same PXM. Otherwise, we use REMOTE_DISTANCE. PXM_INVAL and NID_INVAL are also exported to the ACPI header file so that we can compare node_to_pxm() results in generic code (in this case, the SRAT code).

* acpi: fix potential call to a freed memory section.Aaron Durbin2007-05-17
| | | | | | | | | | | | | | | | | | | | Strip __cpuinit[data] from Node <-> PXM routines and supporting data structures. Also make pxm_to_node_map and node_to_pxm_map local to the numa acpi module. This fixes a bug triggered by the following conditions: - boot on a machine with a SLIT table defined - kernel is configured w/ CONFIG_HOTPLUG_CPU=n - cat /sys/devices/system/node/node*/distance This will cause an oops by calling into a freed memory section. In particular, on x86_64, __node_distance calls node_to_pxm().

But we found that some of the _ADR-Based devices don't have _PRT, i.e. they are not managed by the new ACPI PCI bridge driver. So that .bind method is not called for some _ADR-Based devices, which leads to a failure. Now we make ACPI PCI Root Bridge Driver scan and binds all _ADR-Based devices once the driver is loaded, in the .add method of ACPI PCI Root Bridge driver.
