| | | | | | | | | | | | | | | | | | When rendering to a texture with BaseLevel set, the miptree may be laid out such that BaseLevel is in level 0 of the miptree (to avoid wasting memory on unused levels between 0 and BaseLevel-1). In that case, we have to shift our render target's level down to the appropriate level of the smaller miptree. The WebGL test in combination with a meta code relating to glGenerateMipmap also triggered a similar failure scenario. This GPU hang regression was introduced by c754f7a8.

* mesa: Fix bug in unclamped float to ubyte conversion.Manfred Ernst2013-06-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The IEEE float optimized version of UNCLAMPED_FLOAT_TO_UBYTE in macros.h computed incorrect results for inputs in the range 0x3f7f0000 (=0.99609375) to 0x3f7f7f80 (=0.99803924560546875) inclusive. 0x3f7f7f80 is the IEEE float value that results in 254.5 when multiplied by 255. With rounding mode "round to closest even integer", this is the largest float in the range 0.0-1.0 that is converted to 254 by the generic implementation of UNCLAMPED_FLOAT_TO_UBYTE. The IEEE float optimized version incorrectly defined the cut-off for mapping to 255 as 0x3f7f0000 (=255.0/256.0). The same bug was present in the function float_to_ubyte in u_math.h. Fix: The proposed fix replaces the incorrect cut-off value by 0x3f800000, which is the IEEE float representation of 1.0f. 0x3f7f7f81 (or any value in between) would also work, but 1.0f is probably cleaner.

* i965/gen7+: Disable fast color clears on shared regions.Paul Berry2013-06-124-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | In certain circumstances the memory region underlying a miptree is shared with other miptrees, or with other code outside Mesa's control. This happens, for instance, when an extension like GL_OES_EGL_image or GLX_EXT_texture_from_pixmap extension is used to associate a miptree with an image existing outside of Mesa. When this happens, we need to disable fast color clears on the miptree in question, since there's no good synchronization mechanism to ensure that deferred clear writes get performed by the time the buffer is examined from the other miptree, or from outside of Mesa. Fortunately, this should not be a performance hit for most applications, since most applications that use these extensions use them for importing textures into Mesa, rather than for exporting rendered images out of Mesa. So most of the time the miptrees involved will never experience a clear. v2: Rework based on the fact that we have decided not to use an accessor function to protect access to the region.

This will be needed when a buffer that has experienced a fast color clear is later used for a purpose other than as a render target (texturing, glReadPixels, or swapped to the screen). It resolves any remaining deferred clear operation that was not taken care of during normal rendering. Fortunately not much work is necessary; all we need to do is scale down the size of the rectangle primitive being emitted, run the fragment shader with the "Render Target Resolve Enable" bit set, and ensure that the fragment shader writes to the render target using the "replicated color" message. We already have a fragment shader that does that (the shader that we use for fast color clears), so for simplicity we re-use it. Reviewed-by: Eric Anholt <[email protected]>

* intel: Keep region name in intel_miptree_create_for_dri2_buffer().Paul Berry2013-06-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | When processing a buffer received from the X server, intel_process_dri2_buffer() examines intel_region::name to determine whether it's received a brand new buffer, or the same buffer it received from the X server the last time it made a request. However, this didn't work properly, because in the call to intel_miptree_create_for_dri2_buffer(), we create a fresh intel_region object to represent the buffer, and this was causing us to forget the buffer's previous name. This patch fixes things by copying over the region name when creating the fresh intel_region object. At the moment, this is just a minor performance optimization. However, when fast color clears are added, it will be necessary to ensure that the fast color clear state for a buffer doesn't get discarded the next time we receive that buffer from the X server.

* i965: Emit the depth/stencil state pointer directly, not via atoms.Kenneth Graunke2013-06-117-80/+18
| | | | | | | | | | | | | | | | | | | | | See two commits ago for the rationale. This allows us to delete the whole gen7_cc_state.c file. This does move these commands before the depth stall flushes from brw_emit_depthbuffer, which may be a problem. The documentation for 3DSTATE_DEPTH_BUFFER mentions that depth stall flushes are required before changing any depth/stencil buffer state, but explicitly lists 3DSTATE_DEPTH_BUFFER, 3DSTATE_HIER_DEPTH_BUFFER, 3DSTATE_STENCIL_BUFFER, and 3DSTATE_CLEAR_PARAMS. It does not mention this particular packet (_3DSTATE_DEPTH_STENCIL_STATE_POINTERS). No observed Piglit regressions on Sandybridge or Ivybridge. Together with the last two commits, this makes a cairo-gl benchmark faster by 0.324552% +/- 0.258355% on Ivybridge. No statistically significant change on Sandybridge.

* i965: Emit the BLEND_STATE pointer directly rather than via atoms.Kenneth Graunke2013-06-115-30/+18
| | | | | | | | | | | | | | | | | | | | | | | | Previously, we would: 1. Emit the new indirect state. 2. Flag CACHE_NEW_BLEND_STATE. 3. Rely on later state atoms to notice CACHE_NEW_BLEND_STATE and emit a pointer to the new indirect state. This is rather cumbersome: it requires two state atoms instead of one, and there's a strict ordering dependency in the list. Plus, the code gets spread across two functions (or even files in the case of Gen7+). Gen7+ has a packet to update just the blend state pointer, so it makes a lot of sense to simply emit that right away. Gen6 has a combined packet which updates blending, the color calculator, and depth/stencil state; however, each can still be modified independently. This drops the Gen6 micro-optimization where we tried to only emit one packet that changed all three states. State updates are pretty cheap. CACHE_NEW_BLEND_STATE is no longer necessary, so drop it.
