From 0fcd48bac51f344b805e9cdc32156b0a8efdbba0 Mon Sep 17 00:00:00 2001 From: Gurchetan Singh Date: Mon, 19 Nov 2018 10:28:26 -0800 Subject: [PATCH] virgl: add protocol for resource transfers Mostly similar to VIRGL_CCMD_RESOURCE_INLINE_WRITE. However, this uses the resource's already attached iovecs rather than the command buffer to transfer the data. v2: Used (1 << 16) not (1 << 15) [@gerddie] Reviewed-by: Gert Wollny --- src/gallium/drivers/virgl/virgl_hw.h | 1 + src/gallium/drivers/virgl/virgl_protocol.h | 11 +++++++++++ 2 files changed, 12 insertions(+) diff --git a/src/gallium/drivers/virgl/virgl_hw.h b/src/gallium/drivers/virgl/virgl_hw.h index 8759e57..fec9ce8 100644 --- a/src/gallium/drivers/virgl/virgl_hw.h +++ b/src/gallium/drivers/virgl/virgl_hw.h @@ -234,6 +234,7 @@ enum virgl_formats { #define VIRGL_CAP_GUEST_MAY_INIT_LOG (1 << 14) #define VIRGL_CAP_SRGB_WRITE_CONTROL (1 << 15) #define VIRGL_CAP_QBO (1 << 16) +#define VIRGL_CAP_TRANSFER (1 << 17) /* virgl bind flags - these are compatible with mesa 10.5 gallium. * but are fixed, no other should be passed to virgl either. diff --git a/src/gallium/drivers/virgl/virgl_protocol.h b/src/gallium/drivers/virgl/virgl_protocol.h index 5733355..62b28bd 100644 --- a/src/gallium/drivers/virgl/virgl_protocol.h +++ b/src/gallium/drivers/virgl/virgl_protocol.h @@ -94,6 +94,8 @@ enum virgl_context_cmd { VIRGL_CCMD_SET_ATOMIC_BUFFERS, VIRGL_CCMD_SET_DEBUG_FLAGS, VIRGL_CCMD_GET_QUERY_RESULT_QBO, + VIRGL_CCMD_TRANSFER3D, + VIRGL_CCMD_END_TRANSFERS, }; /* @@ -565,4 +567,13 @@ enum virgl_context_cmd { #define VIRGL_QUERY_RESULT_QBO_OFFSET 5 #define VIRGL_QUERY_RESULT_QBO_INDEX 6 +#define VIRGL_TRANSFER_TO_HOST 1 +#define VIRGL_TRANSFER_FROM_HOST 2 + +/* Transfer */ +#define VIRGL_TRANSFER3D_SIZE 13 +/* The first 11 dwords are the same as VIRGL_RESOURCE_IW_* */ +#define VIRGL_TRANSFER3D_DATA_OFFSET 12 +#define VIRGL_TRANSFER3D_DIRECTION 13 + #endif -- 2.7.4
