2011-02-20video: tegra: Change overlay spinlock to mutexDan Willemsen
We call tegra_overlay_put inside the overlay lock, which can do a flip. It's not safe to do a flip in an atomic context.

2011-02-18video: tegra: nvmap: fix potential deadlockKirill Artamonov
Enabled mutex debugging reavealed potential deadlocks introduced with compaction. Handle spin lock replaced with mutex. Heap functions cannot be protected with spinlock because they call kernel slab allocation functions which cannot be called from atomic context. nvmap_client ref_lock is also replaced with mutex. Otherwise we cannot access heap parameters protected by mutex nvmap_handle lock. Extra locking for handle->owner removed. bug 793364 Change-Id: I635ce9ebf259dd7bf8802457567f93b7be5795ea Reviewed-on: http://git-master/r/19850 Reviewed-by: Kirill Artamonov <kartamonov@nvidia.com> Tested-by: Kirill Artamonov <kartamonov@nvidia.com> Reviewed-by: Daniel Willemsen <dwillemsen@nvidia.com>

Reverting previous hdmi hotplug fix (commit 633a7967cad4454327572f85fbdf5cd88eb68b78). It doesn't seem to fix hotplug problem on ventana, and it is causing tegra_dc_enable() to be called before we set up hdmi mode properly. It's no longer needed when we set ventna_hdmi_enb=1. The 5ms sleep time after tegra_dc_enable() is no longer needed, as the tegra_dc_enable() is removed from tegra_dc_hdmi_detect_worker(). bug 784597 Change-Id: Ibd2ef95f45bec23031e6f839490f06a2832c6931 Reviewed-on: http://git-master/r/17084 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com>

2011-01-31video: tegra: Fix HDMI mirroring corruptionDan Willemsen
The new overlay code had this change commented out, because I hadn't figured out how to get the resolution of the display outside of the fb driver. This change now grabs it from the h_active and v_active of the current mode. Old Change: video: tegra: Fixed the HDMI corruption issue. If internal panel has different resolution compared to HDMI panel, then window attributes are calculated differently, this causes HDMI panel to show corruption. This is fixed by checking actual display resolution while computing window attributes.

2011-01-28nvmap: Optionally check global list for IOC_GET_IDRobert Morell
For NVMAP_IOC_GET_ID, if the requested handle isn't found in the client-private list, check the device-wide handles if allowed (global handles or superuser). The proper way to share memory between clients is to first call IOC_GET_ID from the client who owns the memory, pass the resulting ID to the new client, and then use IOC_FROM_ID in the new client to get a handle. However, some (broken) legacy applications did both IOC_GET_ID and IOC_FROM_ID steps in the new client. To support those applications but hopefully prevent new applications from growing the same behavior, the NVMAP_SEARCH_GLOBAL_HANDLES config option was added that restores the old behavior (default N). Note that even with this option enabled, the client issuing the IOC_GET_ID call must be privileged to access the handle provided. In practice, this means the global list search only works for clients who have opened the /dev/knvmap super device node.
