| * vmwgfx: Reinstate the update_layout ioctlThomas Hellstrom2011-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to redefine a connector as "connected" if it matches a window in the host preferred GUI layout. Otherwise "smart" window managers would turn on Xorg outputs that we don't want to be on. This reinstates the update_layout and adds the following information to the modesetting system. a) Connection status <-> Equivalent to real hardware connection status b) Preferred mode <-> Equivalent to real hardware reading EDID c) Host window position <-> Equivalent to a real hardware scanout address dynamic register. It should be noted that there is no assumption here about what should be displayed and where. Only how to access the host windows. This also bumps minor to signal availability of the new IOCTL.

* vmwgfx: Fix up query processingThomas Hellstrom2011-10-05
| | | | | | | | | | | | | | | | | | | | | | Previously, query results could be placed in any buffer object, but since we didn't allow pinned buffer objects, query results could be written when that buffer was evicted, corrupting data in other buffers. Now, require that buffers holding query results are no more than two pages large, and allow one single pinned such buffer. When the command submission code encounters query result structures in other buffers, the queries in the pinned buffer will be finished using a query barrier for the last hardware context using the buffer. Also if the command submission code detects that a new hardware context is used for queries, all queries of the previous hardware context is also flushed. Currently we use waiting for a no-op occlusion query as a query barrier for a specific context. The query buffer is also flushed and unpinned on context destructions, master drops and before scanout bo placement.
