| * | | | | | | | | | | | | | | genirq: Add IRQ_AFFINITY_MANAGED flagRunmin Wang2017-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add IRQ_AFFINITY_MANAGED flag and related kernel APIs so that kernel driver can modify an irq's status in such a way that user space affinity change will be ignored. Kernel space's affinity setting will not be changed. Change-Id: Ib2d5ea651263bff4317562af69079ad950c9e71e Signed-off-by: Runmin Wang <runminw@codeaurora.org>

Contrary to the IRQ_NO_BALANCING flag, the kernel internal affinity mechanism is not blocked. This flag will be used for multi-queue device interrupts.

This causes audio to mute, as codec is not in proper reset state. Add new lock to synchronize codec subsystem restart APIs.

However, there are some LED class devices which needs the trigger not to be removed. In an use case like camera flash, camera flash driver passes in a trigger device to LED class driver. If the trigger is removed when the brightness is set to 0, this will affect the clients using those triggers. Hence add a flag to always keep the trigger even when brightness is set to 0.

Supporting this tunable correctly would result in complexity that would outweigh any foreseeable benefits. For example, disabling the feature globally would involve deleting all colocation groups one by one while ensuring no placement decisions are made during the process. Remove the tunable. Adding or removing a task from a colocation group is still possible and so we're not losing functionality.

The existing locking solution doesn't work; note that it tries to grab a lock inside the group_leader's context object, which you can only get at by going through a pointer that should be protected from these races. To avoid that problem, and to produce a simple solution, we can just use a lock per group_leader to protect all checks on the group_leader's context. The new lock is grabbed and released when no context locks are held.

For example the placement policy can be more aggressive in using idle CPUs on cluster that are power efficient and less aggressive on clusters that are geared towards performance. Add support for per cluster wake_up_idle flag to allow greater flexibility in placement policies.

The typical way to handle this is for the clk driver or some other early code to call clk_prepare_enable on this important clock as soon as it is registered and before the clk_disable_unused garbage collector kicks in. This patch introduces a formal way to handle this scenario that is provided by the clk framework. Clk driver authors can set the CLK_ENABLE_HAND_OFF flag in their clk data, which will cause the clk to be enabled in clk_register(). Then when the first clk consumer driver comes along and calls clk_get() & clk_prepare_enable(), the reference counts taken during clk registration are transfered (or handed off) to the clk consumer. At this point handling the clk is the same as any other clock which as not set the new CLK_ENABLE_HAND_OFF flag. In fact no changes to any clock consumer driver are needed for this to work.
