2007-10-29Refactor and fix core vblank supportJesse Barnes
Consolidate support for synchronizing to and retrieving vblank counters. Also fix the core vblank code to return monotonic MSC counters, which are required by some GLX extensions. Adding support for multiple pipes to a low level driver is fairly easy, the Intel 965 driver provides simple example code (see intel_buffers.c:intelWindowMoved()). The new code bumps the media stream counter extension version to 2 and adds a new getDrawableMSC callback. This callback takes a drawablePrivate pointer, which is used to calculate the MSC value seen by clients based on the actual vblank counter(s) returned from the kernel. The new drawable private fields are as follows: - vblSeq - used for tracking vblank counts for buffer swapping - vblFlags - flags (e.g. current pipe), updated by low level driver - msc_base - MSC counter from the last time the current pipe changed - vblank_base - kernel DRM vblank counter from the last time the pipe changed Using the above variables, the core vblank code (in vblank.c) can calculate a monotonic MSC value. The low level DRI drivers are responsible for updating the current pipe (by setting VBLANK_FLAG_SECONDARY for example in vblFlags) along with msc_base and vblank_base whenever the pipe associated with a given drawable changes (again, see intelWindowMoved for an example of this). Drivers should fill in the GetDrawableMSC DriverAPIRec field to point to driDrawableGetMSC32 and add code for pipe switching as outlined above to fully support the new scheme.
2007-10-10Drop __DRInativeDisplay and pass in __DRIscreen pointers instead.Kristian Høgsberg
Many DRI entry points took a __DRInativeDisplay pointer and a screen index as arguments. The only use for the native display pointer was to pass it back to the loader when looking up the __DRIscreen for the given screen index. Instead, let's just pass in the __DRIscreen pointer directly, which let's drop the __DRInativeDisplay type and the getScreen function. The assumption is now that the loader will be able to retrieve context from the __DRIscreen pointer when necessary.

2005-01-31Bug #2428: #ifdef GLX_DIRECT_RENDERING in DRI drivers is pointless.Adam Jackson
2004-09-30OK, one more time. Simplify the state-backup system by just storing the fullEric Anholt
state in a ready-to-emit cmdbuf, which avoids the issue Nicolai Haehnle reported where the check() could return differently during backup-and-emit than it should have if it were called at the right time. Move the lit emission before most of the TCL state emission on r200, which fixes neverball issues. Tested with: r100/r200 with neverball, tuxracer, chromium, quake3, ipers
2004-09-22The previous code would emit a full set of state during the first EmitState onEric Anholt
a new cmdbuf, to ensure that state wasn't lost across UNLOCK/LOCK pairs (in the case of context switching). This was rather inefficient. Instead, after flushing a cmdbuf, mark the state as needing to be saved on UNLOCK. Then, at the beginning of flushing a cmdbuf, if we actually have lost the context, go back and emit a new cmdbuf with the full set of state, before continuing with the cmdbuf flush. Also, remove the dirty/clean atom lists, since atoms are emitted in a fixed order these days, and go with a simpler single list. Provides a 14% improvement in ipers performance in my tests, along with other apps.
2004-08-17Close some races with locking on R100 and R200 which could manifest as renderingEric Anholt
errors on r100 and rendering errors and hangs on r200 (same for R100 without OLD_PACKETS). If a command buffer filled after some state (EmitState or a VBPNTR write) was emitted, the lock was grabbed, the buffer flushed, a new buffer prepared, and the lock dropped. Another client could come in, set its own state as part of rendering, and when the first client flushed the rendering commands depending on the previous state, it got the 2nd client's state. This is fixed by checking for enough space before beginning a set of state emits and rendering, and flushing the buffer first if so. This guarantees that the buffer won't wrap. Also, move the "lost_context = 1" from the end of cmdbuf flushing to UNLOCK_HARDWARE for clarity (at a minimum) that any time the lock is dropped, state may get overwritten. We don't have enough information at the point of the LOCK_HARDWARE to reset our state to the last UNLOCK_HARDWARE point in the case that we did lose our context, but saving the information to rebuild that state may be a useful optimization (ipers data suggests up to 5%).

uses the NEW_INTERFACE now so _SOLO isn't necessary anymore. Tested with the hardware that I own.

2004-01-20Before calling _mesa_create_context(), initialize a dd_function_table structBrian Paul
by calling _mesa_init_driver_functions() and then plugging in the driver- specific functions. In particular, make sure ctx->Driver.NewTextureObject points to the appropriate driver function so that _all_ texture objects are augmented with the driver-specific data. Put in a bunch of assertions in the texture-related driver functions that texObj->DriverData is valid. Remove old dead code in near future.
