* mesa/i965: Refactor brw_is_front_buffer_{drawing,reading} to common codeIan Romanick2015-10-061-22/+2

* i965: Always intel_prepare_render() after invalidating front buffers.Kenneth Graunke2014-05-061-0/+2
| | | | | | | | | | | | | | | Fixes glean/texture_srgb, which hit recursive-flush prevention assertions in vbo_exec_FlushVertices. This probably hurts the performance of front buffer rendering, but very few people in their right mind do front buffer rendering. Fixes Glean's texture_srgb test.

* i965: Drop intel_check_front_buffer_rendering().Eric Anholt2014-03-111-18/+0
| | | | | | | | | This was being applied in a subset of the places that intel_prepare_render() was called, to set the same flag that intel_prepare_render() was setting. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>
* i965: Drop broken front_buffer_reading/drawing optimization.Eric Anholt2014-03-111-17/+27
| | | | | | | | | | | | The flag wasn't getting updated correctly when the ctx->DrawBuffer or ctx->ReadBuffer changed. It usually ended up working out because most apps only have one window system framebuffer, or if they have more than one and they have any front read/drawing, they will have called glReadBuffer()/glDrawBuffer() on it when they get started on the new buffer.

* intel: When checking for updating front buffer reading, use the right fb.Eric Anholt2014-03-111-1/+1
| | | | | | | | | | | | | It's the ctx->ReadBuffer that gets read from, not the ctx->DrawBuffer. So, if you happened to have a ctx->ReadBuffer that was the winsys buffer, and it had previously been intel_prepare_render()ed but not invalidated since then, and you called glReadBuffer() to switch to front buffer instead of back buffer reading on the winsys fbo while your drawbuffer was a user FBO, you'd never get the front buffer's miptree fetched, and segfault.

| | | | | | | | | | | | | | This makes brw_context available in every function that used intel_context. This makes it possible to start migrating fields from intel_context to brw_context.

| | | | | | | | * Fix crash at context creation in most drivers supporting vblank. * Don't pass vblank sequence or flags to functions that get passed the drawable private already. * Attempt to initialize vblank related drawable private fields just once per drawable. May need more work in some drivers.
* Refactor and fix core vblank supportJesse Barnes2007-10-291-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | passing them to the kernel. This works because all drawing commands in the 965 driver are emitted with the lock held and the batchbuffer is always flushed prior to releasing the lock. This allows multiple cliprects to be dealt with, without replaying entire batchbuffers and redundantly re-emitting state.
