Field Documentation

◆ alpha_blit

int(* alpha_blit) (DrmDriver *driver, DrmSurfaceBuffer *src_buf, const GAL_Rect *src_rc, DrmSurfaceBuffer *dst_buf, const GAL_Rect *dst_rc, uint8_t alpha)

This operation blits pixles from a source buffer with the source alpha value specified to a destination buffer.

Note: If this operation is set as NULL, the driver does not support hardware accelerated blit with alpha.

Definition at line 282 of file exstubs.h.

◆ alpha_key_blit

int(* alpha_key_blit) (DrmDriver *driver, DrmSurfaceBuffer *src_buf, const GAL_Rect *src_rc, DrmSurfaceBuffer *dst_buf, const GAL_Rect *dst_rc, uint8_t alpha, uint32_t color_key)

This operation blits pixles from a source buffer with the source alpha value specified to a destination buffer, but skipping the pixel value specified.

Note: If this operation is set as NULL, the driver does not support hardware accelerated blit with alpha and color key.

Definition at line 304 of file exstubs.h.

◆ check_blit

int(* check_blit) (DrmDriver *driver, DrmSurfaceBuffer *src_buf, DrmSurfaceBuffer *dst_buf)

This operation checks whether a hardware accelerated blit can be done between the source buffer and the destination buffer. If succeed, it returns 0.

Note: If this operation is set as NULL, it will be supposed that the driver does not support any hardware accelerated blit operation.

Definition at line 261 of file exstubs.h.

◆ clear_buffer

int(* clear_buffer) (DrmDriver *driver, DrmSurfaceBuffer *dst_buf, const GAL_Rect *rc, uint32_t pixel_value)

This operation clears the specific rectangle area of a buffer with the specific pixel value. If succeed, it returns 0.

Note: If this operation is set as NULL, the driver does not support hardware accelerated clear operation.

Definition at line 250 of file exstubs.h.

◆ copy_blit

int(* copy_blit) (DrmDriver *driver, DrmSurfaceBuffer *src_buf, const GAL_Rect *src_rc, DrmSurfaceBuffer *dst_buf, const GAL_Rect *dst_rc, enum DrmColorLogicOp logic_op)

This operation copies bits from a source buffer to a destination buffer.

Note: If this operation is set as NULL, the driver does not support hardware accelerated copy blit.

Definition at line 270 of file exstubs.h.

◆ create_buffer

DrmSurfaceBuffer*(* create_buffer) (DrmDriver *driver, uint32_t drm_format, unsigned int width, unsigned int height)

This operation creates a buffer with the specified pixel format, width, and height. If succeed, a valid DrmSurfaceBuffer object will be returned; NULL on error. Note that the field of pixels of the DrmSurfaceBuffer object is NULL until the map_buffer was called.

Note: The driver must implement this operation.

Definition at line 184 of file exstubs.h.

◆ create_buffer_from_handle

DrmSurfaceBuffer*(* create_buffer_from_handle) (DrmDriver *driver, uint32_t handle, unsigned long size, uint32_t drm_format, unsigned int width, unsigned int height, unsigned int pitch)

This operation creates a buffer for the given handle with the specified pixel format, width, and height. If succeed, a valid DrmSurfaceBuffer object will be returned; NULL on error.

Note: This operation can be NULL.

Definition at line 195 of file exstubs.h.

◆ create_buffer_from_name

DrmSurfaceBuffer*(* create_buffer_from_name) (DrmDriver *driver, uint32_t name, uint32_t drm_format, unsigned int width, unsigned int height, unsigned int pitch)

This operation creates a buffer for the given system global name with the specified pixel format, width, and height. If succeed, a valid DrmSurfaceBuffer object will be returned; NULL on error.

Note: This operation can be NULL.

Definition at line 206 of file exstubs.h.

◆ create_buffer_from_prime_fd

DrmSurfaceBuffer*(* create_buffer_from_prime_fd) (DrmDriver *driver, int prime_fd, unsigned long size, uint32_t drm_format, unsigned int width, unsigned int height, unsigned int pitch)

This operation creates a buffer for the given PRIME file descriptor with the specified pixel format, width, height, and pitch. If succeed, a valid DrmSurfaceBuffer object will be returned; NULL on error.

Note: This operation can be NULL.

Definition at line 217 of file exstubs.h.

◆ create_driver

DrmDriver*(* create_driver) (int device_fd)

This operation creates the DrmDriver object.

Note: The driver must implement this operation.

Definition at line 160 of file exstubs.h.

◆ destroy_buffer

void(* destroy_buffer) (DrmDriver *driver, DrmSurfaceBuffer *buffer)

This operation destroies a buffer.

Note: The driver must implement this operation.

Definition at line 241 of file exstubs.h.

◆ destroy_driver

void(* destroy_driver) (DrmDriver *driver)

This operation destroies the DrmDriver object.

Note: The driver must implement this operation.

Definition at line 167 of file exstubs.h.

◆ flush_driver

void(* flush_driver) (DrmDriver *driver)

This operation flushs the batch buffer of the driver or the hardware cache.

Note: This operation can be NULL.

Definition at line 174 of file exstubs.h.

◆ key_blit

int(* key_blit) (DrmDriver *driver, DrmSurfaceBuffer *src_buf, const GAL_Rect *src_rc, DrmSurfaceBuffer *dst_buf, const GAL_Rect *dst_rc, uint32_t color_key)

This operation blits pixles from a source buffer to a destination buffer, but skipping the pixel value specified by color_key.

Note: If this operation is set as NULL, the driver does not support hardware accelerated blit with color key.

Definition at line 293 of file exstubs.h.

◆ map_buffer

uint8_t*(* map_buffer) (DrmDriver *driver, DrmSurfaceBuffer *buffer)

This operation maps the buffer into the current process's virtual memory space, and returns the virtual address. If failed, it returns NULL.

Note: The driver must implement this operation.

Definition at line 227 of file exstubs.h.

◆ unmap_buffer

void(* unmap_buffer) (DrmDriver *driver, DrmSurfaceBuffer *buffer)

This operation un-maps a buffer.

Note: The driver must implement this operation.
