2012-06-25video: tegra: host: add public APIs for power & syncpoint managementMayuresh Kulkarni
- add public APIs for power & sync-point management - all these APIs end with string _ext - all these APIs can be found in linux/nvhost.h - all these APIs take nvhost_device as first argument - all these APIs are based on the fact that host1x hardware driver is parent of all the host1x client driver - this allows clients of host1x which are outside host1x driver code to just include nvhost.h & use host1x driver interfaces - this also hides the implementation details of power & sync-point inside host1x driver code - move sync point ids for dc and nvavp to nvhost.h Bug 961009 Change-Id: I1a9ca074df87656c4d4bd246853e039a7850d56a Signed-off-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> Reviewed-on: http://git-master/r/109219 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> GVS: Gerrit_Virtual_Submit

2012-05-17video: tegra: host: Do not panic on hardware timeoutTerje Bergstrom
nvhost panics if hardware does not respond within 30 seconds. Remove this behavior, as it causes problems in emulation and simulation. Panic should be used only to prevent corruption. Submits are now given a default timeout of 30 seconds. The clients can still override with their own timeout value. MPE doesn't provide the number of slots for context save/restore. This information is needed to be able to use the submit timeout for MPE.

2012-01-30video: tegra: host: CPU reg read to use power managementTerje Bergstrom
CPU register read did not have access to nvhost power management. Due to this only modules that were powered on previously are actually accessible via the API. This patch refactors CPU access to: * Move mutexes to sync point, as they're sync point operations * Move register address spaces to nvhost_device * Call register read with access to the respective nvhost_device * Initialize module completely at boot-up so that register reads can be done without an initialized channel.

The kernel now receives wait tracking data (similar to gathers and relocs) and compares the current syncpt with the threshold value. If it's old, it gets a kernel mapping and rewrites the method data to use a kernel reserved syncpt that is always 0 (so trivially pops when seen by the HW).

2011-11-30video: tegra: host1x driverGary King
the graphics and display hardware on tegra SoCs is accessed through a command DMA front-end called host1x host driver clients place commands into memory objects called streams, and submit a stream on one of 8 channels: the assignment of streams-to-channels depends on the hardware module(s) programmed by the stream: for example, all streams which program the 3D hardware are submitted on channel 1. the host1x hardware includes two synchronization primitives to allow command streams to synchronize access to memory or to hardware engines shared across channels (e.g. the 2D blitter): sync points and module mutexes. both primitives can also be used to synchronize with the CPU. the host1x driver performs power management for all modules behind the host block: once a module is idle (i.e., the last stream which accesses it has completed, indicated by a syncpoint) and has remained idle for an extended period of time, the module's clock (and power gate island, if the module is uniquely power-gated) is disabled, and will be automatically re-enabled when a new stream is submitted for that module. includes channel debugging support originally implemented by Erik Gilling <konkers@google.com> Original Author: Antti Hatala <ahatala@nvidia.com> Signed-off-by: Gary King <gking@nvidia.com> Change-Id: Idf0ecc8e7710f3839903a9fbfbe5650990a96b2c
