From 89b4798c0619a2ba99046d5ad36f0e6851625f7a Mon Sep 17 00:00:00 2001 From: Gurchetan Singh Date: Mon, 26 Nov 2018 09:54:05 -0800 Subject: [PATCH] virgl: don't mark buffers as unclean after a write We can mark the buffer unclean if it's ever bound as a TBO, SSBO, ABO, or image. This improves dEQP-GLES3.performance.buffer.data_upload.function_call.map_buffer_range.new_specified_buffer.flag_write_full.stream_draw from 9.58 MB/s to 451.17 MB/s. v2: Track buffer cleanliness as a function of bindings (Ilia). v3: virgl_modify_clean --> virgl_dirty_res (Erik) Tested-By: Gert Wollny Reviewed-by: Erik Faye-Lund --- src/gallium/drivers/virgl/virgl_buffer.c | 1 - src/gallium/drivers/virgl/virgl_encode.c | 10 ++++++++++ 2 files changed, 10 insertions(+), 1 deletion(-) diff --git a/src/gallium/drivers/virgl/virgl_buffer.c b/src/gallium/drivers/virgl/virgl_buffer.c index 88a22b56f9a..f72c93f4995 100644 --- a/src/gallium/drivers/virgl/virgl_buffer.c +++ b/src/gallium/drivers/virgl/virgl_buffer.c @@ -106,7 +106,6 @@ static void virgl_buffer_transfer_unmap(struct pipe_context *ctx, if (trans->base.usage & PIPE_TRANSFER_WRITE) { if (!(transfer->usage & PIPE_TRANSFER_FLUSH_EXPLICIT)) { struct virgl_screen *vs = virgl_screen(ctx->screen); - vbuf->base.clean = FALSE; vctx->num_transfers++; vs->vws->transfer_put(vs->vws, vbuf->base.hw_res, &transfer->box, trans->base.stride, trans->base.layer_stride, trans->offset, transfer->level); diff --git a/src/gallium/drivers/virgl/virgl_encode.c b/src/gallium/drivers/virgl/virgl_encode.c index 400ba684742..49d95de8353 100644 --- a/src/gallium/drivers/virgl/virgl_encode.c +++ b/src/gallium/drivers/virgl/virgl_encode.c @@ -61,6 +61,12 @@ static void virgl_encoder_write_res(struct virgl_context *ctx, } } +static void virgl_dirty_res(struct virgl_resource *res) +{ + if (res) + res->clean = FALSE; +} + int virgl_encode_bind_object(struct virgl_context *ctx, uint32_t handle, uint32_t object) { @@ -615,6 +621,7 @@ int virgl_encode_sampler_view(struct virgl_context *ctx, if (res->u.b.target == PIPE_BUFFER) { virgl_encoder_write_dword(ctx->cbuf, state->u.buf.offset / elem_size); virgl_encoder_write_dword(ctx->cbuf, (state->u.buf.offset + state->u.buf.size) / elem_size - 1); + virgl_dirty_res(res); } else { virgl_encoder_write_dword(ctx->cbuf, state->u.tex.first_layer | state->u.tex.last_layer << 16); virgl_encoder_write_dword(ctx->cbuf, state->u.tex.first_level | state->u.tex.last_level << 8); @@ -949,6 +956,7 @@ int virgl_encode_set_shader_buffers(struct virgl_context *ctx, virgl_encoder_write_dword(ctx->cbuf, buffers[i].buffer_offset); virgl_encoder_write_dword(ctx->cbuf, buffers[i].buffer_size); virgl_encoder_write_res(ctx, res); + virgl_dirty_res(res); } else { virgl_encoder_write_dword(ctx->cbuf, 0); virgl_encoder_write_dword(ctx->cbuf, 0); @@ -972,6 +980,7 @@ int virgl_encode_set_hw_atomic_buffers(struct virgl_context *ctx, virgl_encoder_write_dword(ctx->cbuf, buffers[i].buffer_offset); virgl_encoder_write_dword(ctx->cbuf, buffers[i].buffer_size); virgl_encoder_write_res(ctx, res); + virgl_dirty_res(res); } else { virgl_encoder_write_dword(ctx->cbuf, 0); virgl_encoder_write_dword(ctx->cbuf, 0); @@ -999,6 +1008,7 @@ int virgl_encode_set_shader_images(struct virgl_context *ctx, virgl_encoder_write_dword(ctx->cbuf, images[i].u.buf.offset); virgl_encoder_write_dword(ctx->cbuf, images[i].u.buf.size); virgl_encoder_write_res(ctx, res); + virgl_dirty_res(res); } else { virgl_encoder_write_dword(ctx->cbuf, 0); virgl_encoder_write_dword(ctx->cbuf, 0); -- 2.30.2
