2012-05-11video: tegra: host: move chip_support out of nvhost_masterMayuresh Kulkarni
- currently, nvhost_master holds the reference to struct chip_support - the struct chip_support hides the chip specific implementation for channel submit, cdma, push buffer operations etc. so it exposed all the internal structures through nvhost_master - move chip_support to be a part of nvhost_bus since it only has function pointers to chip specific api implementations - nvhost_master is host1x device specific private data so ideally it should not hold reference to chip specifics Bug 871237 Change-Id: I4f3f48ee5fc47a90288d110ea8eef905150275a0 Signed-off-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> Reviewed-on: http://git-master/r/94421 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> GVS: Gerrit_Virtual_Submit

Currently nvhost hard codes usage of context handler and sync point id. Split the context handler and context structures into generic and host1x specific parts, and move the allocation to happen via a function pointer in nvhost_device. Also updates gr3d and mpe to use sync point id and waitbase from nvhost_device.

2011-11-30video: tegra: nvhost: add submit timeout supportChris Johnson
In this change, nvhost_cdma starts a timer (if a timeout is specified in the userctx), for the buffer at the head of the sync_queue that has not reached its syncpt threshold. If the timeout fires, nvhost_cdma initiates a channel / module reset. It then detects up to where in the sync_queue it stopped execution (based on the current HW syncpt value). For any remaining uncompleted buffers in the context, nvhost_cdma NOPs the entry and CPU incrs the syncpt to where it should be had it completed. If one of the sync_queue entries belongs to another context, it still does the syncpt incrs for this context, but via the PB as a GATHER opcode, At the end, CDMA is restarted, so buffers are refetched (either with NOP slots, or GATHERs to incr syncpts). This appears as though the buffer has completed (and the associated resources released). For testing, debugfs entries have been added under /d/tegra_nvhost force_timeout_val - set the timeout value, in ms force_timeout_channel - channel ID, were timeouts checks occur force_timeout_pid - process ID to set the userctx The idea is to set the timeout_val, then the timeout_channel (e.g. for 3D, the channel ID is 1) and then the process ID, gotten from running adb shell ps.

2011-11-30[ARM/tegra] nvhost: Merge NVIDIA changes into Google's nvhostAndrew Howe
Google's 2.6.36 nvhost driver branched from NVIDIA's 2.6.32 nvhost at some point before it was actually committed to 2.6.32, but the former's original commit included some fixes that were added to the latter after that. Confusing... Also Google's version has some changes that we like so they will remain, but that makes merging difficult. Anyway, this commit brings the rest of our 2.6.32 changes into 2.6.36 and cleans it up a bit. It might be nicer to break this up into a load of smaller commits but it turned out to be very difficult to do that.

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
