◆ mir_connection_allocate_buffer_gbm
typedef void(* mir_connection_allocate_buffer_gbm) (MirConnection *connection, int width, int height, unsigned int gbm_pixel_format, unsigned int gbm_bo_flags, MirBufferCallback available_callback, void *available_context) |
Allocate a MirBuffer via gbm.
available in V1 and V2.
The callback will be called when the buffer is available for use. It will be called once when created, and once per every mir_presentation_chain_submit_buffer.
The buffer can be destroyed via mir_buffer_release().
- Note
- Not all formats or flags are available, and allocations may fail. Be sure to check mir_buffer_is_valid() on the returned buffer.
- Parameters
-
[in] | connection | The connection |
[in] | width | Requested buffer width |
[in] | height | Requested buffer height |
[in] | gbm_pixel_format | The pixel format, one of the GBM_FORMATs |
[in] | gbm_bo_flags | The gbm_bo_flags for the buffer. |
[in] | available_callback | The callback called when the buffer is available |
[in] | available_context | The context for the available_callback |
◆ MirBufferGbmAge
typedef unsigned int(* MirBufferGbmAge) (MirBuffer *buffer) |

- Precondition
- The buffer is suitable for GBM_BO_IMPORT_FD
- Parameters
-
- Returns
- The age of the buffer
◆ MirBufferGbmFd
typedef int(* MirBufferGbmFd) (MirBuffer *buffer) |
Access the fd a MirBuffer suitable for gbm import.
- Precondition
- The buffer is suitable for GBM_BO_IMPORT_FD
- Warning
- The fd is owned by the buffer. Do not close() it.
- Parameters
-
- Returns
- The fd
◆ MirBufferGbmFlags
typedef uint32_t(* MirBufferGbmFlags) (MirBuffer *buffer) |
Get the gbm_bo_flags of a MirBuffer.
- Precondition

- Parameters
-
- Returns
- The gbm_bo_flags of the buffer
◆ MirBufferGbmFormat
typedef uint32_t(* MirBufferGbmFormat) (MirBuffer *buffer) |
Get the GBM_FORMAT of a MirBuffer.
- Precondition

- Parameters
-
- Returns
- The stride of the buffer
◆ MirBufferIsGbmImportable
typedef bool(* MirBufferIsGbmImportable) (MirBuffer *buffer) |
Check if a MirBuffer is suitable for import via GBM_BO_IMPORT_FD.
- Parameters
-
- Returns
- True if suitable, false if unsuitable

typedef void(* MirConnectionAllocateBufferGbm) (MirConnection *connection, uint32_t width, uint32_t height, uint32_t gbm_pixel_format, uint32_t gbm_bo_flags, MirBufferCallback available_callback, void *available_context) |
v2 version of mir_connection_allocate_buffer_gbm, with more accurate types.
◆ MirConnectionAllocateBufferGbmSync
typedef MirBuffer*(* MirConnectionAllocateBufferGbmSync) (MirConnection *connection, uint32_t width, uint32_t height, uint32_t gbm_pixel_format, uint32_t gbm_bo_flags) |
Allocate a MirBuffer via gbm and wait for the allocation.
available in V2. The buffer can be destroyed via mir_buffer_release().
- Parameters
