9 years agocpuquiet: Fix race in runnable governor
Peter Boonstoppel [Wed, 5 Dec 2012 18:45:53 +0000 (10:45 -0800)]
cpuquiet: Fix race in runnable governor

Fixed a race where the cpuquiet driver would call device_free() before
the governor was started, which would lead to a kernel panic because
runnables_timer was not initialized.

Introduced RUNNING state, so states are:
- DISABLED: truly disabled
- IDLE: enabled, but not polling upon request from the driver
- RUNNING: actively polling

cpuquiet: Update averaging of nr_runnables

Doing a Exponential moving average per nr_running++/-- does not
guarantee a fixed sample rate which induces errors if there are lots of
threads being enqueued/dequeued from the rq (Linpack mt). Instead of
keeping track of the avg, the scheduler now keeps track of the integral
of nr_running and allows the readers to perform filtering on top.

Implemented a proper exponential moving average for the runnables
governor and a straight 100ms average for the balanced governor. Tweaked
the thresholds for the runnables governor to minimize latency. Also,
decreased sample_rate for the runnables governor to the absolute minimum
of 10msecs.

Updated to K3.4

9 years agodma: pl330: use dma_addr_t for describing bus addresses

dma: pl330: use dma_addr_t for describing bus addresses

The microcode bus address (pl330_dmac.mcode_bus) is currently a u32,
which fails to compile when building on a system with 64-bit bus
addresses.

This patch uses dma_addr_t to represent the address instead.
