* jump_label, x86: Fix section mismatchPeter Zijlstra2011-12-06
| | | | | | | | | | | | | | | WARNING: arch/x86/kernel/built-in.o(.text+0x4c71): Section mismatch in reference from the function arch_jump_label_transform_static() to the function .init.text:text_poke_early() The function arch_jump_label_transform_static() references the function __init text_poke_early(). This is often because arch_jump_label_transform_static lacks a __init annotation or the annotation of text_poke_early is wrong.

* perf, x86: Fix event scheduler for constraints with overlapping countersRobert Richter2011-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current x86 event scheduler fails to resolve scheduling problems of certain combinations of events and constraints. This happens if the counter mask of such an event is not a subset of any other counter mask of a constraint with an equal or higher weight, e.g. constraints of the AMD family 15h pmu: counter mask weight amd_f15_PMC30 0x09 2 <--- overlapping counters amd_f15_PMC20 0x07 3 amd_f15_PMC53 0x38 3 The scheduler does not find then an existing solution. Here is an example: event code counter failure possible solution 0x02E PMC[3,0] 0 3 0x043 PMC[2:0] 1 0 0x045 PMC[2:0] 2 1 0x046 PMC[2:0] FAIL 2 The event scheduler may not select the correct counter in the first cycle because it needs to know which subsequent events will be scheduled. It may fail to schedule the events then. To solve this, we now save the scheduler state of events with overlapping counter counstraints. If we fail to schedule the events we rollback to those states and try to use another free counter. Constraints with overlapping counters are marked with a new introduced overlap flag. We set the overlap flag for such constraints to give the scheduler a hint which events to select for counter rescheduling. The EVENT_CONSTRAINT_OVERLAP() macro can be used for this. Care must be taken as the rescheduling algorithm is O(n!) which will increase scheduling cycles for an over-commited system dramatically. The number of such EVENT_CONSTRAINT_OVERLAP() macros and its counter masks must be kept at a minimum. Thus, the current stack is limited to 2 states to limit the number of loops the algorithm takes in the worst case. On systems with no overlapping-counter constraints, this implementation does not increase the loop count compared to the previous algorithm. V2: * Renamed redo -> overlap. * Reimplementation using perf scheduling helper functions. V3: * Added WARN_ON_ONCE() if out of save states. * Changed function interface of perf_sched_restore_state() to use bool as return value.

* perf, x86: Implement event scheduler helper functionsRobert Richter2011-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces x86 perf scheduler code helper functions. We need this to later add more complex functionality to support overlapping counter constraints (next patch). The algorithm is modified so that the range of weight values is now generated from the constraints. There shouldn't be other functional changes. With the helper functions the scheduler is controlled. There are functions to initialize, traverse the event list, find unused counters etc. The scheduler keeps its own state. V3: * Added macro for_each_set_bit_cont(). * Changed functions interfaces of perf_sched_find_counter() and perf_sched_next_event() to use bool as return value. * Added some comments to make code better understandable. V4: * Fix broken event assignment if weight of the first event is not wmin (perf_sched_init()).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AMD family 10h we see firmware bug messages like the following: [Firmware Bug]: cpu 6, try to use APIC500 (LVT offset 0) for vector 0x10400, but the register is already in use for vector 0xf9 on another cpu [Firmware Bug]: cpu 6, IBS interrupt offset 0 not available (MSRC001103A=0x0000000000000100) [Firmware Bug]: using offset 1 for IBS interrupts [Firmware Bug]: workaround enabled for IBS LVT offset perf: AMD IBS detected (0x00000007) We always see this, since the offsets are not assigned by the BIOS for this family. Force LVT offset assignment in this case. If the OS assignment fails, fallback to BIOS settings and try to setup this. The fallback to BIOS settings weakens the family check since force_ibs_eilvt_setup() may fail e.g. in case of virtual machines. But setup may still succeed if BIOS offsets are correct. Other families don't have a workaround implemented that assigns LVT offsets. It's ok, to drop calling force_ibs_eilvt_setup() for that families. With the patch the [Firmware Bug] messages vanish.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the core offcore support is fixed up (thanks Stephane) and we have sane generic events utilizing them, re-enable the raw access to the feature as well. Note that it doesn't matter if you use event 0x1b7 or 0x1bb to specify an offcore event, either one works and neither guarantees you'll end up on a particular offcore MSR.

The recent runtime PM changes interact rather badly with the lazy disabling of clocks late in the boot process through the clock framework, leading to situations where the runtime suspend/resume paths are entered without a clock being actively driven due to having been lazily gated off. In order to correct this we can trivially tie in the aforementioned stub as a general fallback for all SH platforms that don't presently have their own runtime PM implementations (the corner case being SH-based SH-Mobile platforms, which have their own stub through the hwblk API -- which in turn has bitrotted and will be subsequently adapted to use the same stub as everyone else), regardless of whether the platforms choose to define power domains of their own or not. This fixes up regressions for clock framework users who also build in runtime PM support without any specific power domains of their own, which was previously causing the serial console to be lost when warring with lazy clock disabling.

| | | * | | | | | arm/tegra: Don't create duplicate gpio and pinmux devicesStephen Warren2011-11-09

In this case, if we register the devices, they end up being probed once due to this registration, and a second time due to a device-tree node (or vice-versa). The second probe fails since the memory regions are already requested. Besides, we don't actually want the duplicated devices. To avoid this duplicate registration, modify *_pinmux_init() to check whether it's running on a DT machine. If not, register the pinmux devices. If so, don't register them. Finally, modify board-dt.c to call the *_pinmux_init() after all devices have been instantiated from device-tree. This allows the GPIO and pinmux devices to be instantiated and initialized before calling functions to configure the hardware. This has one disadvantage: The pinmux and GPIO initialization now happens after /all/ devices are instantiated, rather than after just gpio and pinmux but before anything else. So the correct HW configuration is not in place when e.g. the SD/MMC device is probed. Long-term, this should be solved by doing both: a) Initializing the HW state from DT nodes during GPIO and pinmux device probe. b) Using the deferred driver probe mechanism, so that drivers can defer their probe until after the gpio and pinmux drivers have probed. v2: s/int is_dt/bool is_dt/ v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing an explicit parameter into the function from outside.
