Previously we would re-upload the constant data to the batchbuffer, then re-emit the packets. We only need to do the last step (causing the existing data in the batchbuffer to be re-uploaded to the push constant staging area in the L3).
Now that we've separated the two, it's pretty easy to accomplish. --- src/mesa/drivers/dri/i965/gen7_urb.c | 6 +++++- src/mesa/drivers/dri/i965/genX_state_upload.c | 9 ++------- 2 files changed, 7 insertions(+), 8 deletions(-) diff --git a/src/mesa/drivers/dri/i965/gen7_urb.c b/src/mesa/drivers/dri/i965/gen7_urb.c index 525c9c4d3da..8e614b1176e 100644 --- a/src/mesa/drivers/dri/i965/gen7_urb.c +++ b/src/mesa/drivers/dri/i965/gen7_urb.c @@ -101,7 +101,11 @@ gen7_allocate_push_constants(struct brw_context *brw) * Similar text exists for the other 3DSTATE_PUSH_CONSTANT_ALLOC_* * commands. */ - brw->ctx.NewDriverState |= BRW_NEW_PUSH_CONSTANT_ALLOCATION; + brw->vs.base.push_constants_dirty = true; + brw->tcs.base.push_constants_dirty = true; + brw->tes.base.push_constants_dirty = true; + brw->gs.base.push_constants_dirty = true; + brw->wm.base.push_constants_dirty = true; } void diff --git a/src/mesa/drivers/dri/i965/genX_state_upload.c b/src/mesa/drivers/dri/i965/genX_state_upload.c index a8641a31768..264e999b86a 100644 --- a/src/mesa/drivers/dri/i965/genX_state_upload.c +++ b/src/mesa/drivers/dri/i965/genX_state_upload.c @@ -2816,7 +2816,6 @@ static const struct brw_tracked_state genX(vs_push_constants) = { _NEW_TRANSFORM, .brw = BRW_NEW_BATCH | BRW_NEW_BLORP | - BRW_NEW_PUSH_CONSTANT_ALLOCATION | BRW_NEW_VERTEX_PROGRAM | BRW_NEW_VS_PROG_DATA, }, @@ -2847,8 +2846,7 @@ static const struct brw_tracked_state genX(gs_push_constants) = { .brw = BRW_NEW_BATCH | BRW_NEW_BLORP | BRW_NEW_GEOMETRY_PROGRAM | - BRW_NEW_GS_PROG_DATA | - BRW_NEW_PUSH_CONSTANT_ALLOCATION, + BRW_NEW_GS_PROG_DATA, }, .emit = genX(upload_gs_push_constants), }; @@ -2873,8 +2871,7 @@ static const struct brw_tracked_state genX(wm_push_constants) = { .brw = BRW_NEW_BATCH | BRW_NEW_BLORP | BRW_NEW_FRAGMENT_PROGRAM | - BRW_NEW_FS_PROG_DATA | - BRW_NEW_PUSH_CONSTANT_ALLOCATION, + BRW_NEW_FS_PROG_DATA, }, .emit = genX(upload_wm_push_constants), }; @@ -3690,7 +3687,6 @@ static const struct brw_tracked_state genX(tes_push_constants) = { .mesa = _NEW_PROGRAM_CONSTANTS, .brw = BRW_NEW_BATCH | BRW_NEW_BLORP | - BRW_NEW_PUSH_CONSTANT_ALLOCATION | BRW_NEW_TESS_PROGRAMS | BRW_NEW_TES_PROG_DATA, }, @@ -3720,7 +3716,6 @@ static const struct brw_tracked_state genX(tcs_push_constants) = { .brw = BRW_NEW_BATCH | BRW_NEW_BLORP | BRW_NEW_DEFAULT_TESS_LEVELS | - BRW_NEW_PUSH_CONSTANT_ALLOCATION | BRW_NEW_TESS_PROGRAMS | BRW_NEW_TCS_PROG_DATA, }, -- 2.13.2 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
