Adreno 225 support #2

starks · 2013-06-20T06:56:54Z

A lot of devices from 2012 use the MSM8960 SoC which includes the Adreno 225 GPU which is not supported by Mesa or the Fedora installer.

Attempting to run Mesa on the Galaxy S3 results in the phone abruptly rebooting.

https://github.com/freedreno/mesa/blob/master/src/gallium/drivers/freedreno/freedreno_screen.c#L401

Per your recommendations, I'd like to try modifying the above to forcibly accept a 225, but seeing as I can't even get X working, I don't think it matters.

With the recent SRGB changes all my automated OpenGL llvmpipe tests (piglit, conform, glretrace) start asserting with the backtrace below. I'm hoping this change will fix it. I'm not entirely sure, as this doesn't happen in my development machine (the bug probably depends on the exact X visual). Anyway, it seems the sensible thing to do here.

So when checking/building sse code we have three possibilities: 1 Old compiler, throws an error when using -msse* 2 New compiler, user disables sse* (-mno-sse*) 3 New compiler, user doesn't disable sse The original code, added code for #1 but not #2. Later on we patched around the lack of handling #2 by wrapping the code in __SSE4_1__. Yet it lead to a missing/undefined symbol in case of #1 or #2, which might cause an issue for #2 when using the i965 driver. A bit later we "fixed" the undefined symbol by using #1, rather than updating it to handle #2. With this commit we set things straight :) To top it all up, conventions state that in case of conflicting (-enable-foo -disable-foo) options, the latter one takes precedence. Thus we need to make sure to prepend -msse4.1 to CFLAGS in our test. v2: Clean the #includes. Suggested by Ilia, Matt & Siavash.

This is a partial revert of c893069. It split the {start,base}_vertex_location handling into several steps: 1. Set brw->draw.start_vertex_location = prim[i].start and brw->draw.base_vertex_location = prim[i].basevertex. (This happened once per _mesa_prim, in the main drawing loop.) 2. Add brw->vb.start_vertex_bias and brw->ib.start_vertex_offset appropriately. (This happened in brw_prepare_shader_draw_parameters, which was called just after brw_prepare_vertices, as part of state upload, and only happened when BRW_NEW_VERTICES was flagged.) 3. Use those values when emitting 3DPRIMITIVE (once per _mesa_prim). If we drew multiple _mesa_prims, but didn't flag BRW_NEW_VERTICES on the second (or later) primitives, we would do step #1, but not #2. The first _mesa_prim would get correct values, but subsequent ones would only get the first half of the summation. The reason I originally did this was because I needed the value of gl_BaseVertexARB to exist in a buffer object prior to uploading 3DSTATE_VERTEX_BUFFERS. I believed I wanted to upload the value of 3DPRIMITIVE's "Base Vertex Location" field, which was computed as: (prims[i].indexed ? prims[i].start : prims[i].basevertex) + brw->vb.start_vertex_bias. The latter value wasn't available until after brw_prepare_vertices, and the former weren't available in the state upload code at all. Hence the awkward split. However, I believe that including brw->vb.start_vertex_bias was a mistake. It's an extra bias we apply when uploading vertex data into VBOs, to move [min_index, max_index] to [0, max_index - min_index]. >From the GL_ARB_shader_draw_parameters specification: "<gl_BaseVertexARB> holds the integer value passed to the <baseVertex> parameter to the command that resulted in the current shader invocation. In the case where the command has no <baseVertex> parameter, the value of <gl_BaseVertexARB> is zero." I conclude that gl_BaseVertexARB should only include the baseVertex parameter from glDraw*Elements*, not any internal biases we add for optimization purposes. With that in mind, gl_BaseVertexARB only needs prim[i].start or prim[i].basevertex. We can simply store that, and go back to computing start_vertex_location and base_vertex_location in brw_emit_prim(), like we used to. This is much simpler, and should actually fix two bugs. Fixes missing geometry in Unvanquished.

Equivalent to commit 8ac3b52 but with sel operations. In this case we select the PredCtrl based on the writemask. This patch helps on cases like this: 1: cmp.l.f0.0 vgrf40.0.x:F, vgrf0.zzzz:F, vgrf7.xxxx:F 2: cmp.nz.f0.0 null:D, vgrf40.xxxx:D, 0D 3: (+f0.0) sel vgrf41.0.x:UD, vgrf6.xxxx:UD, vgrf5.xxxx:UD In this case, cmod propagation can't optimize instruction #2, because instructions #1 and #2 have different writemasks, and we can't update directly instruction #2 writemask because our code thinks that sel at instruction #3 reads all four channels of the flag, when it actually only reads .x. So, with this patch, the previous case becames this: 1: cmp.l.f0.0 vgrf40.0.x:F, vgrf0.zzzz:F, vgrf7.xxxx:F 2: cmp.nz.f0.0 null:D, vgrf40.xxxx:D, 0D 3: (+f0.0.x) sel vgrf41.0.x:UD, vgrf6.xxxx:UD, vgrf5.xxxx:UD Now only the x channel of the flag is used, allowing dead code eliminate to update the writemask at the second instruction: 1: cmp.l.f0.0 vgrf40.0.x:F, vgrf0.zzzz:F, vgrf7.xxxx:F 2: cmp.nz.f0.0 null.x:D, vgrf40.xxxx:D, 0D 3: (+f0.0.x) sel vgrf41.0.x:UD, vgrf6.xxxx:UD, vgrf5.xxxx:UD So now cmod propagation can simplify out #2: 1: cmp.l.f0.0 vgrf40.0.x:F, attr18.wwww:F, vgrf7.xxxx:F 2: (+f0.0.x) sel vgrf41.0.x:UD, vgrf6.xxxx:UD, vgrf5.xxxx:UD Shader-db numbers: total instructions in shared programs: 6235835 -> 6228008 (-0.13%) instructions in affected programs: 219850 -> 212023 (-3.56%) total loops in shared programs: 1979 -> 1979 (0.00%) helped: 1192 HURT: 0
