2011-09-06video: tegra: Implement EDID queryRobert Morell
This change implements the TEGRA_DC_EXT_CONTROL_GET_OUTPUT_EDID ioctl in the dc_ext interface. It first adds a way for the tegra dc EDID module to export EDID data safely, without the risk of reading an incomplete or corrupted EDID in the presence of hotplug, by moving the actual data to a substructure with a lifetime maintained by a kref. Then, that support is plumbed through the hdmi block (which is currently the only way to get at the EDID) and out to userspace.

2011-09-06video: tegra: dc: Separate allocations for U and VRobert Morell
Currently, dc_ext only takes a single nvmap memory ID per overlay, even in the YUV case (the U and V planes are expected to be differentiated using an offset from the beginning of the nvmap allocation). This is problematic for some software flows, such as certain video interlacing algorithms that will vary the luma plane while keeping the chrome plane constant. This change allows dc_ext clients to specify a different nvmap allocation for each of the Y, U, and V planes. If a YUV surface is used and no U or V plane allocation is specified, the old behavior is preserved: the U and V offsets are assumed to be within the same allocation as Y. Note: this changes the behavior of the offset parameter: the old code added offset to offset_u and offset_v when using it. The new code treats all three offsets as relative to the beginning of the allocation. It also fixes a bug in the code where offset was applied twice to the Y plane. I believe this is safe because the presence of this bug means that no existing clients are using offset != 0 (or if they are, they're already broken).

2011-08-22video: 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.

2011-08-22video: tegra: dc_ext: Add head status ioctlRobert Morell
This change adds a new tegra_dc_ext ioctl to allow userspace to query whether a head is currently enabled or not. This is necessary for the X server to be able to restore the outputs that were enabled before it was started. bug 818525 Original-Change-Id: I6d209894081312621f623a722cdd3fcb53553c61 Signed-off-by: Robert Morell <rmorell@nvidia.com> Reviewed-by: Aaron Plattner <aplattner@nvidia.com> Reviewed-by: Olof Johansson <olofj@chromium.org> Reviewed-on: http://git-master/r/40530 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>
2011-08-22video: tegra: Expose vblank syncpointRobert Morell
This change adds support for userspace to query the syncpoint that display autoincrements every vblank. This can be useful for applications to time buffer submissions to throttle rendering and prevent excessive host stalls. bug 818525 Original-Change-Id: I050e4dcd08609da802f10eeec5b70da181b21717 Signed-off-by: Robert Morell <rmorell@nvidia.com> Reviewed-on: http://git-master/r/40529 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>
2011-08-22video: tegra: Expose possible bound head maskRobert Morell
This change adds support for userspace to query which heads an output may be bound to. Since our implementation currently hardcodes the head to output mapping, we currently always fill in a single bit. However, for future implementations we will be able to dynamically bind outputs to heads. bug 818525 Original-Change-Id: Ib0dead7748620a538c8f8d6ef548ca8b13a9c2b2 Signed-off-by: Robert Morell <rmorell@nvidia.com> Reviewed-on: http://git-master/r/40528 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>
2011-08-22video: tegra: Add userspace CSC controlRobert Morell
This adds configurability of the per-window color space conversion support in the Tegra display controller through the dc extension interface. The CSC matrix defaults to its previously-hardcoded values, but can be overridden by userspace. bug 818525 Original-Change-Id: I00d8e48dd38a40e5b8c36d4624d31c834e5cd9de Signed-off-by: Robert Morell <rmorell@nvidia.com> Reviewed-on: http://git-master/r/40527 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>

This change makes the input rect for Tegra windows be a 20.12 fixed-point number instead of an integer. This allows software to specify sub-pixel precision. bug 818525 Original-Change-Id: I130f63b68159ed896d1113ea537307997875ca40 Signed-off-by: Robert Morell <rmorell@nvidia.com> Reviewed-on: http://git-master/r/40526 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>
