From: Stanimir Varbanov Date: Thu, 26 May 2016 22:10:37 +0000 (+0300) Subject: gallium: push offset down to driver X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e382bc649b95aa2ab6e86d60b0520236b2bf2947;p=mesa.git gallium: push offset down to driver Push offset down to drivers when importing dmabuf. This is needed to more fully support EGL_EXT_image_dma_buf_import when a non-zero offset is specified. Tesing has been done for freedreno, and compile tested following gallium drivers: nouveau,svga,virgl,r600,r300,radeonsi,swrast,i915,ilo Signed-off-by: Stanimir Varbanov Reviewed-by: Emil Velikov --- diff --git a/src/gallium/drivers/nouveau/nouveau_screen.c b/src/gallium/drivers/nouveau/nouveau_screen.c index 4ca9e5c06cd..2c421cc748c 100644 --- a/src/gallium/drivers/nouveau/nouveau_screen.c +++ b/src/gallium/drivers/nouveau/nouveau_screen.c @@ -89,6 +89,12 @@ nouveau_screen_bo_from_handle(struct pipe_screen *pscreen, struct nouveau_bo *bo = 0; int ret; + if (whandle->offset != 0) { + debug_printf("%s: attempt to import unsupported winsys offset %d\n", + __FUNCTION__, whandle->offset); + return NULL; + } + if (whandle->type != DRM_API_HANDLE_TYPE_SHARED && whandle->type != DRM_API_HANDLE_TYPE_FD) { debug_printf("%s: attempt to import unsupported handle type %d\n", diff --git a/src/gallium/drivers/vc4/vc4_screen.c b/src/gallium/drivers/vc4/vc4_screen.c index 5ab1682b25a..733275a8f7b 100644 --- a/src/gallium/drivers/vc4/vc4_screen.c +++ b/src/gallium/drivers/vc4/vc4_screen.c @@ -559,6 +559,13 @@ vc4_screen_bo_from_handle(struct pipe_screen *pscreen, { struct vc4_screen *screen = vc4_screen(pscreen); + if (whandle->offset != 0) { + fprintf(stderr, + "Attempt to import unsupported winsys offset %u\n", + whandle->offset); + return NULL; + } + switch (whandle->type) { case DRM_API_HANDLE_TYPE_SHARED: return vc4_bo_open_name(screen, whandle->handle, whandle->stride); diff --git a/src/gallium/state_trackers/dri/dri2.c b/src/gallium/state_trackers/dri/dri2.c index 182d4e6b3e2..8dea6715d7d 100644 --- a/src/gallium/state_trackers/dri/dri2.c +++ b/src/gallium/state_trackers/dri/dri2.c @@ -790,8 +790,6 @@ dri2_create_image_from_winsys(__DRIscreen *_screen, templ.depth0 = 1; templ.array_size = 1; - whandle->offset = 0; - img->texture = screen->base.screen->resource_from_handle(screen->base.screen, &templ, whandle, PIPE_HANDLE_USAGE_READ_WRITE); if (!img->texture) { @@ -842,7 +840,7 @@ dri2_create_image_from_fd(__DRIscreen *_screen, __DRIimage *img = NULL; unsigned err = __DRI_IMAGE_ERROR_SUCCESS; - if (num_fds != 1 || offsets[0] != 0) { + if (num_fds != 1) { err = __DRI_IMAGE_ERROR_BAD_MATCH; goto exit; } @@ -1056,8 +1054,6 @@ dri2_from_names(__DRIscreen *screen, int width, int height, int format, if (num_names != 1) return NULL; - if (offsets[0] != 0) - return NULL; format = convert_fourcc(format, &dri_components); if (format == -1) @@ -1067,6 +1063,7 @@ dri2_from_names(__DRIscreen *screen, int width, int height, int format, whandle.type = DRM_API_HANDLE_TYPE_SHARED; whandle.handle = names[0]; whandle.stride = strides[0]; + whandle.offset = offsets[0]; img = dri2_create_image_from_winsys(screen, width, height, format, &whandle, loaderPrivate); diff --git a/src/gallium/winsys/i915/drm/i915_drm_buffer.c b/src/gallium/winsys/i915/drm/i915_drm_buffer.c index c0698529e1c..ba454ecf54c 100644 --- a/src/gallium/winsys/i915/drm/i915_drm_buffer.c +++ b/src/gallium/winsys/i915/drm/i915_drm_buffer.c @@ -101,6 +101,9 @@ i915_drm_buffer_from_handle(struct i915_winsys *iws, if ((whandle->type != DRM_API_HANDLE_TYPE_SHARED) && (whandle->type != DRM_API_HANDLE_TYPE_FD)) return NULL; + if (whandle->offset != 0) + return NULL; + buf = CALLOC_STRUCT(i915_drm_buffer); if (!buf) return NULL; diff --git a/src/gallium/winsys/intel/drm/intel_drm_winsys.c b/src/gallium/winsys/intel/drm/intel_drm_winsys.c index 1c5aabe3304..d3bc4303077 100644 --- a/src/gallium/winsys/intel/drm/intel_drm_winsys.c +++ b/src/gallium/winsys/intel/drm/intel_drm_winsys.c @@ -313,6 +313,11 @@ intel_winsys_import_handle(struct intel_winsys *winsys, drm_intel_bo *bo; int err; + if (handle->offset != 0) { + debug_error("attempt to import unsupported winsys offset"); + return NULL; + } + switch (handle->type) { case DRM_API_HANDLE_TYPE_SHARED: { diff --git a/src/gallium/winsys/radeon/drm/radeon_drm_bo.c b/src/gallium/winsys/radeon/drm/radeon_drm_bo.c index 950cbb3e55f..2c10e2eb622 100644 --- a/src/gallium/winsys/radeon/drm/radeon_drm_bo.c +++ b/src/gallium/winsys/radeon/drm/radeon_drm_bo.c @@ -858,6 +858,12 @@ static struct pb_buffer *radeon_winsys_bo_from_handle(struct radeon_winsys *rws, unsigned handle; uint64_t size = 0; + if (!offset && whandle->offset != 0) { + fprintf(stderr, "attempt to import unsupported winsys offset %u\n", + whandle->offset); + return NULL; + } + /* We must maintain a list of pairs , so that we always return * the same BO for one particular handle.
