* dri_util: Don't assume __DRIcontext->driverPrivate is a gl_contextKristian Høgsberg2013-12-1314-10/+34
| | | | | | | | | | | | | | | | | The driverPrivate pointer is opaque to the driver and we can't assume it's a struct gl_context in dri_util.c. Instead provide a helper function to set the struct gl_context flags from the incoming DRI context flags. v2 (idr): Modify the other classic drivers to also use driContextSetFlags. I ran all the piglit GLX_ARB_create_context tests with i965 and classic swrast without regressions.

* swrast* (gallium, classic): add MESA_copy_sub_buffer support (v3)Dave Airlie2013-12-133-1/+54
| | | | | | | | | | | | | | | | | | | | | | | This patches add MESA_copy_sub_buffer support to the dri sw loader and then to gallium state tracker, llvmpipe, softpipe and other bits. It reuses the dri1 driver extension interface, and it updates the swrast loader interface for a new putimage which can take a stride. I've tested this with gnome-shell with a cogl hacked to reenable sub copies for llvmpipe and the one piglit test. I could probably split this patch up as well. v2: pass a pipe_box, to reduce the entrypoints, as per Jose's review, add to p_screen doc comments. v3: finish off winsys interfaces, add swrast classic support as well.

* glsl/loops: replace loop controls with a normative bound.Paul Berry2013-12-092-4/+8
| | | | | | | | | | | | | | This patch replaces the ir_loop fields "from", "to", "increment", "counter", and "cmp" with a single integer ("normative_bound") that serves the same purpose. I've used the name "normative_bound" to emphasize the fact that the back-end is required to emit code to prevent the loop from running more than normative_bound times. (By contrast, an "informative" bound would be a bound that is informational only). Reviewed-by: Jordan Justen <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl/loops: consolidate bounded loop handling into a lowering pass.Paul Berry2013-12-093-63/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, all of the back-ends (ir_to_mesa, st_glsl_to_tgsi, and the i965 fs and vec4 visitors) had nearly identical logic for handling bounded loops. This replaces the duplicate logic with an equivalent lowering pass that is used by all the back-ends. Note: on i965, there is a slight increase in instruction count. For example, a loop like this: for (int i = 0; i < 100; i++) { total += i; } would previously compile down to this (vec4) native code: mov(8) g4<1>.xD 0D mov(8) g8<1>.xD 0D loop: cmp.ge.f0(8) null g8<4;4,1>.xD 100D (+f0) break(8) add(8) g5<1>.xD g5<4;4,1>.xD g4<4;4,1>.xD add(8) g8<1>.xD g8<4;4,1>.xD 1D add(8) g4<1>.xD g4<4;4,1>.xD 1D while(8) loop After this patch, the "(+f0) break(8)" turns into: (+f0) if(8) break(8) endif(8) because the back-end isn't smart enough to recognize that "if (condition) break;" can be done using a conditional break instruction. However, it should be relatively easy for a future peephole optimization to properly optimize this. Reviewed-by: Jordan Justen <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* i965/blorp: allow multisample blorp clearsPaul Berry2013-12-091-18/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we didn't do multisample blorp clears because we couldn't figure out how to get them to work. The reason for this was because we weren't setting the brw_blorp_params num_samples field consistently with dst.num_samples. Now that those two fields have been collapsed down into one, we can do multisample blorp clears. However, we need to do a few other pieces of bookkeeping to make them work correctly in all circumstances: - Since blorp clears may now operate on multisampled window system framebuffers, they need to call intel_renderbuffer_set_needs_downsample() to ensure that a downsample happens before buffer swap (or glReadPixels()). - When clearing a layered multisample buffer attachment using UMS or CMS layout, we need to advance layer by multiples of num_samples (since each logical layer is associated with num_samples physical layers). Note: we still don't do multisample fast color clears; more work needs to be done to enable those.

| | | | | | | | | | | | | | | Previously, brw_blorp_params contained two fields for determining sample count: num_samples (which determined the multisample configuration of the rendering pipeline) and dst.num_samples (which determined the multisample configuration of the render target surface). This was redundant, since both fields had to be set to the same value to avoid rendering errors. This patch eliminates num_samples to avoid future confusion.

* i965/gen7+: Disentangle MSAA layout from fast clear state.Paul Berry2013-12-093-48/+47
| | | | | | | | | | | | | | | | This patch renames the enum that's used to keep track of fast clear state from "mcs_state" to "fast_clear_state", and it removes the enum value INTEL_MCS_STATE_MSAA (which previously meant, "this is an MSAA buffer, so we're not keeping track of fast clear state"). The only real purpose that enum value was serving was to prevent us from trying to do fast clear resolves on MSAA buffers, and it's just as easy to prevent that by checking the buffer's msaa_layout. This paves the way for implementing fast clears of MSAA buffers.

| | | | | | | | | | | | | | | | The "layer" parameters used in blorp, and the intel_renderbuffer::mt_layer field, represent a physical layer rather than a logical layer. This is important for 2D multisample arrays on Gen7+ because the UMS and CMS multisample layouts use N physical layers to represent each logical layer, where N is the number of samples. Also add an assertion to blorp to help catch bugs if we fail to follow these conventions.

| | | | | | | | | | | | | | | | | | | | We need to emit extra shader code in this case to sample the MCS surface first; we can't just blindly do this all the time since IVB will sometimes try to access the MCS surface even if disabled. V3: Use actual MSAA layout from the texture's mt, rather then computing what would have been used based on the format. This is simpler and less fragile - there's at least one case where we might want to have a texture's MSAA layout change based on what the app does (CMS SINT falling back to UMS if the app ever attempts to render to it with a channel disabled.) This also obsoletes V2's 1/10 -- compute_msaa_layout can now remain an implementation detail of the miptree code.
