| * | ACPI: track opregion names to avoid driver resource conflicts.Thomas Renninger2008-02-07
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Small ACPICA extension to be able to store the name of operation regions in osl.c later In ACPI, AML can define accesses to IO ports and System Memory by Operation Regions. Those are not registered as done by PNPACPI using resource templates (and _CRS/_SRS methods). The IO ports and System Memory regions may get accessed by arbitrary AML code. When native drivers are accessing the same resources bad things can happen (e.g. a critical shutdown temperature of 3000 C every 2 months or so). It is not really possible to register the operation regions via request_resource, as they often overlap with pnp or other resources (e.g. statically setup IO resources below 0x100). This approach stores all Operation Region declarations (IO and System Memory only) at ACPI table parse time. It offers a similar functionality like request_region and let drivers which are known to possibly use the same IO ports and Memory which are also often used by ACPI (hwmon and i2c) check for ACPI interference. A boot parameter acpi_enforce_resources=strict/lax/no is provided, which is default set to lax: - strict: let conflicting drivers fail to load with an error message - lax: let conflicting driver work normal with a warning message - no: no functional change at all Depending on the feedback and the kind of interferences we see, this should be set to strict at later time. Goal of this patch set is: - Identify ACPI interferences in bug reports (very hard to reproduce and to identify) - Find BIOSes for that an ACPI driver should exist for specific HW instead of a native one. - stability in general Provide acpi_check_{mem_}region. Drivers can additionally check against possible ACPI interference by also invoking this shortly before they call request_region. If -EBUSY is returned, the driver must not load. Use acpi_enforce_resources=strict/lax/no options to: - strict: let conflicting drivers fail to load with an error message - lax: let conflicting driver work normal with a warning message - no: no functional change at all Cc: "Mark M.

| * | ACPI : Update T-state coordination after getting _TSD infoZhao Yakui2008-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Accordint to ACPI spec, the _TSD object provides T-state control cross logical processor dependency information to OSPM. After the _TSD data for all cpus are obtained, OSPM will set up the T-state coordination between CPUs. Of course if the _TSD doesn't exist or _TSD data is incorrect , it is assumed that there is no T-state coordination and T-state is changed independently. Now there is no proper solution to update T-state coordination after one cpu is hotplugged. So this patch won't support hotplugged cpu very well.

What it does: Parses the _WDG method and exports functions to process WMI method calls, data block query/ set commands (both based on GUID) and does basic event handling. How: WMI presents an in kernel interface here (essentially, a minimal wrapper around ACPI) (const char *guid assume the 36 character ASCII representation of a GUID - e.g. 67C3371D-95A3-4C37-BB61-DD47B491DAAB) wmi_evaluate_method(const char *guid, u8 instance, u32 method_id, const struct acpi_buffer *in, struct acpi_buffer *out) wmi_query_block(const char *guid, u8 instance, struct acpi_buffer *out) wmi_set_block(const char *guid, u38 instance, const struct acpi_buffer *in) wmi_install_notify_handler(acpi_notify_handler handler); wmi_remove_notify_handler(void); wmi_get_event_data(u32 event, struct acpi_buffer *out) wmi_has_guid(const char guid*) wmi_has_guid() is a helper function to find if a GUID exists or not on the system (a quick and easy way for WMI dependant drivers to see if the the method/ block they want exists, since GUIDs are supposed to be unique). Event handling - allow a WMI based driver to register a notifier handler for each GUID with WMI. When a notification is sent to a GUID in WMI, the handler registered with WMI is then called (it is left to the caller to ask for the WMI event data associated with the GUID, if needed). What it won't do: Unicode - The MS article[1] calls for converting between ASCII and Unicode (or vice versa) if a GUID is marked as "string". This is left up to the calling driver. Handle a MOF[1] - the WMI mapper just exports methods, data and events to userspace. MOF handling is down to userspace. Userspace interface - this will be added later. [1] http://www.microsoft.com/whdc/system/pnppwr/wmi/wmi-acpi.mspx === ChangeLog == v1 (2007-10-02): * Initial release v2 (2007-10-05): * Cleaned up code - split up super "wmi_evaluate_block" -> each external symbol now handles its own ACPI calls, rather than handing off to a "super" method (and in turn, is a lot simpler to read) * Added a find_guid() symbol - return true if a given GUID exists on the system * wmi_* functions now return type acpi_status (since they are just fancy wrappers around acpi_evaluate_object()) * Removed extra debug code v3 (2007-10-27) * More code clean up - now passes checkpatch.pl * Change data block calls - ref MS spec, method ID is not required for them, so drop it from the function parameters. * Const'ify guid in the function call parameters. * Fix _WDG buffer handling - copy the data to our own private structure. * Change WMI from tristate to bool - otherwise the external functions are not exported in linux/acpi.h if you try to build WMI as a module. * Fix more flag comparisons. * Add a maintainers entry - since I wrote this, I should take the blame for it. v4 (2007-10-30) * Add missing brace from after fixing checkpatch errors. * Rewrote event handling - allow external drivers to register with WMI to handle WMI events * Clean up flags and sanitise flag handling v5 (2007-11-03) * Add sysfs interface for userspace. Export events over netlink again. * Remove module left overs, fully convert to built-in driver. * Tweak in-kernel API to use u8 for instance, since this is what the GUID blocks use (so instance cannot be greater than u8). * Export wmi_get_event_data() for in kernel WMI drivers. v6 (2007-11-07) * Split out userspace into a different patch v7 (2007-11-20) * Fix driver to handle multiple PNP0C14 devices - store all GUIDs using the kernel's built in list functions, and just keep adding to the list every time we handle a PNP0C14 devices - GUIDs will always be unique, and WMI callers do not know or care about different devices. * Change WMI event handler registration to use its' own event handling struct; we should not pass an acpi_handle down to any WMI based drivers - they should be able to function with only the calls provided in WMI. * Update my e-mail address v8 (2007-11-28) * Convert back to a module. * Update Kconfig to default to building as a module. * Remove an erroneous printk. * Simply comments for string flag (since we now leave the handling to the caller). v9 (2007-12-07) * Add back missing MODULE_DEVICE_TABLE for autoloading * Checkpatch fixes v10 (2007-12-12) * Workaround broken GUIDs declared expensive without a WCxx method. * Minor cleanups v11 (2007-12-17) * More fixing for broken GUIDs declared expensive without a WCxx method. * Add basic EmbeddedControl region handling. v12 (2007-12-18) * Changed EC region handling code, as per Alexey's comments. v13 (2007-12-27) * Changed event handling so that we can have one event handler registered per GUID, as per Matthew Garrett's suggestion. v14 (2008-01-12) * Remove ACPI debug statements v15 (2008-02-01) * Replace two remaining 'x == NULL' type tests with '!x' v16 (2008-02-05) * Change MAINTAINERS entry, as I am not, and never have been, paid to work on WMI * Remove 'default' line from Kconfig Signed-off-by: Carlos Corbacho <carlos@strangeworlds.co.uk> CC: Matthew Garrett <mjg59@srcf.ucam.org> CC: Alexey Starikovskiy <aystarik@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com>

The root of the tree is the RSDP (Root System Description Pointer). To find the RSDP, the OS searches for the signature "RSD PTR " in well known physical memory locations. Then the OS computes a table checksum to verify that the signature is really part of a valid table header. Some systems have a proper signature but an invalid checksum; followed elsewhere by a proper signature with valid checksum. http://bugzilla.kernel.org/show_bug.cgi?id=9444 The Linux RSDP scanning code bailed out on those systems and as a result they booted with ACPI disabled. Fix this by deleting the Linux RSDP scanning code and plugging in the ACPICA RSDP scanning code. Signed-off-by: Len Brown <len.brown@intel.com>

Removing these methods allows drivers to have all transaction parameters available at 'prep' time, saves two function pointers in struct dma_async_tx_descriptor, and reduces the number of indirect branches.. A consequence of moving this data to the 'prep' routine is that multi-source routines like async_xor need temporary storage to convert an array of linear addresses into an array of dma addresses. In order to keep the same stack footprint of the previous implementation the input array is reused as storage for the dma addresses. This requires that sizeof(dma_addr_t) be less than or equal to sizeof(void *). As a consequence CONFIG_DMADEVICES now depends on !CONFIG_HIGHMEM64G. It also requires that drivers be able to make descriptor resources available when the 'prep' routine is polled.
