Subject: [RFC PATCH 0/2] OMAP: PM: add devices wakeup latency constraints APIs
Date: Thu, 10 Feb 2011 20:23:25 +0100 [thread overview]
Message-ID: <1297365807-12143-1-git-send-email-j-pihet@ti.com> (raw)
From: Jean Pihet <j-pihet@ti.com>
- Implement OMAP PM layer omap_pm_set_max_dev_wakeup_lat API.
- Created arch/arm/plat-omap/omap-pm-constraints.c file from
arch/arm/plat-omap/omap-pm-noop.c and the associated Kconfig option
OMAP_PM_CONSTRAINTS.
This code is an early submission in RFC state and is for review only.
Testing is on-going.
ToDo:
- implement the API for the SDMA device (omap_pm_set_max_sdma_lat),
- change the power domains latency figures to some more realistic values,
- add the hook to the existing kernel PM QoS interfaces (cpu_dma_latency),
cf. Documentation/power/pm_qos_interface.txt
