Reality is that it is -a struct dma_buf*, but advertising it as such to other drivers seems -to encourage the use of it as such, and I'm not sure on the implications -of that. - -Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org> ---- - drivers/staging/vc04_services/vc-sm-cma/vc_sm.c | 10 +++++----- - drivers/staging/vc04_services/vc-sm-cma/vc_sm_knl.h | 6 +++--- - drivers/staging/vc04_services/vchiq-mmal/mmal-common.h | 2 +- - drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c | 2 +- - 4 files changed, 10 insertions(+), 10 deletions(-) - ---- a/drivers/staging/vc04_services/vc-sm-cma/vc_sm.c -+++ b/drivers/staging/vc04_services/vc-sm-cma/vc_sm.c -@@ -745,7 +745,7 @@ static int bcm2835_vc_sm_cma_remove(stru - } - - /* Get an internal resource handle mapped from the external one. */ --int vc_sm_cma_int_handle(int handle) -+int vc_sm_cma_int_handle(void *handle) - { - struct dma_buf *dma_buf = (struct dma_buf *)handle; - struct vc_sm_buffer *res; -@@ -762,7 +762,7 @@ int vc_sm_cma_int_handle(int handle) - EXPORT_SYMBOL_GPL(vc_sm_cma_int_handle); - - /* Free a previously allocated shared memory handle and block. */ --int vc_sm_cma_free(int handle) -+int vc_sm_cma_free(void *handle) - { - struct dma_buf *dma_buf = (struct dma_buf *)handle; - -@@ -772,7 +772,7 @@ int vc_sm_cma_free(int handle) - return -EPERM; - } - -- pr_debug("%s: handle %08x/dmabuf %p\n", __func__, handle, dma_buf); -+ pr_debug("%s: handle %p/dmabuf %p\n", __func__, handle, dma_buf); - - dma_buf_put(dma_buf); - -@@ -781,7 +781,7 @@ int vc_sm_cma_free(int handle) - EXPORT_SYMBOL_GPL(vc_sm_cma_free); - - /* Import a dmabuf to be shared with VC. */ --int vc_sm_cma_import_dmabuf(struct dma_buf *src_dmabuf, int *handle) -+int vc_sm_cma_import_dmabuf(struct dma_buf *src_dmabuf, void **handle) - { - struct dma_buf *new_dma_buf; - struct vc_sm_buffer *res; -@@ -801,7 +801,7 @@ int vc_sm_cma_import_dmabuf(struct dma_b - res = (struct vc_sm_buffer *)new_dma_buf->priv; - - /* Assign valid handle at this time.*/ -- *handle = (int)new_dma_buf; -+ *handle = new_dma_buf; - } else { - /* - * succeeded in importing the dma_buf, but then ---- a/drivers/staging/vc04_services/vc-sm-cma/vc_sm_knl.h -+++ b/drivers/staging/vc04_services/vc-sm-cma/vc_sm_knl.h -@@ -17,12 +17,12 @@ - #endif - - /* Free a previously allocated or imported shared memory handle and block. */ --int vc_sm_cma_free(int handle); -+int vc_sm_cma_free(void *handle); - - /* Get an internal resource handle mapped from the external one. */ --int vc_sm_cma_int_handle(int handle); -+int vc_sm_cma_int_handle(void *handle); - - /* Import a block of memory into the GPU space. */ --int vc_sm_cma_import_dmabuf(struct dma_buf *dmabuf, int *handle); -+int vc_sm_cma_import_dmabuf(struct dma_buf *dmabuf, void **handle); - - #endif /* __VC_SM_KNL_H__INCLUDED__ */ ---- a/drivers/staging/vc04_services/vchiq-mmal/mmal-common.h -+++ b/drivers/staging/vc04_services/vchiq-mmal/mmal-common.h -@@ -52,7 +52,7 @@ struct mmal_buffer { - struct mmal_msg_context *msg_context; - - struct dma_buf *dma_buf;/* Exported dmabuf fd from videobuf2 */ -- int vcsm_handle; /* VCSM handle having imported the dmabuf */ -+ void *vcsm_handle; /* VCSM handle having imported the dmabuf */ - u32 vc_handle; /* VC handle to that dmabuf */ - - u32 cmd; /* MMAL command. 0=data. */ ---- a/drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c -+++ b/drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c -@@ -1794,7 +1794,7 @@ int mmal_vchi_buffer_cleanup(struct mmal - if (buf->vcsm_handle) { - int ret; - -- pr_debug("%s: vc_sm_cma_free on handle %08X\n", __func__, -+ pr_debug("%s: vc_sm_cma_free on handle %p\n", __func__, - buf->vcsm_handle); - ret = vc_sm_cma_free(buf->vcsm_handle); - if (ret) |
