Changes since v4: - Set fb_id at init instead of memclear() and set (Eric Engestrom) Changes since v3: - remove unnecessary null check in drmModeFreeFB2 (Daniel Stone) Changes since v2: - getfb2 ioctl has been merged upstream - sync include/drm/drm.h in a seperate patch Changes since v1: - functions should be drm_public - modifier should be 64 bits - update ioctl number Signed-off-by: Juston Li Signed-off-by: Daniel Stone --- xf86drmMode.c | 33 +++++++++++++++++++++++++++++++++ xf86drmMode.h | 15 +++++++++++++++ 2 files changed, 48 insertions(+) diff --git a/xf86drmMode.c b/xf86drmMode.c index 0cf7992c6e9a..2eb7b765cce8 100644 --- a/xf86drmMode.c +++ b/xf86drmMode.c @@ -1594,3 +1594,36 @@ drmModeRevokeLease(int fd, uint32_t lessee_id) return 0; return -errno; } + +drm_public drmModeFB2Ptr +drmModeGetFB2(int fd, uint32_t fb_id) +{ + struct drm_mode_fb_cmd2 get = { .fb_id = fb_id, }; + drmModeFB2Ptr ret; + int err; + + err = DRM_IOCTL(fd, DRM_IOCTL_MODE_GETFB2, &get); + if (err != 0) + return NULL; + + ret = drmMalloc(sizeof(drmModeFB2)); + if (!ret) + return NULL; + + ret->fb_id = fb_id; + ret->width = get.width; + ret->height = get.height; + ret->pixel_format = get.pixel_format; + ret->flags = get.flags; + ret->modifier = get.modifier[0]; + memcpy(ret->handles, get.handles, sizeof(uint32_t) * 4); + memcpy(ret->pitches, get.pitches, sizeof(uint32_t) * 4); + memcpy(ret->offsets, get.offsets, sizeof(uint32_t) * 4); + + return ret; +} + +drm_public void drmModeFreeFB2(drmModeFB2Ptr ptr) +{ + drmFree(ptr); +} diff --git a/xf86drmMode.h b/xf86drmMode.h index 159a39937240..fc0bbd8dcb67 100644 --- a/xf86drmMode.h +++ b/xf86drmMode.h @@ -225,6 +225,19 @@ typedef struct _drmModeFB { uint32_t handle; } drmModeFB, *drmModeFBPtr; +typedef struct _drmModeFB2 { + uint32_t fb_id; + uint32_t width, height; + uint32_t pixel_format; /* fourcc code from drm_fourcc.h */ + uint64_t modifier; /* applies to all buffers */ + uint32_t flags; + + /* per-plane GEM handle; may be duplicate entries for multiple planes */ + uint32_t handles[4]; + uint32_t pitches[4]; /* bytes */ + uint32_t offsets[4]; /* bytes */ +} drmModeFB2, *drmModeFB2Ptr; + typedef struct drm_clip_rect drmModeClip, *drmModeClipPtr; typedef struct _drmModePropertyBlob { @@ -343,6 +356,7 @@ typedef struct _drmModePlaneRes { extern void drmModeFreeModeInfo( drmModeModeInfoPtr ptr ); extern void drmModeFreeResources( drmModeResPtr ptr ); extern void drmModeFreeFB( drmModeFBPtr ptr ); +extern void drmModeFreeFB2( drmModeFB2Ptr ptr ); extern void drmModeFreeCrtc( drmModeCrtcPtr ptr ); extern void drmModeFreeConnector( drmModeConnectorPtr ptr ); extern void drmModeFreeEncoder( drmModeEncoderPtr ptr ); @@ -362,6 +376,7 @@ extern drmModeResPtr drmModeGetResources(int fd); * Retrieve information about framebuffer bufferId */ extern drmModeFBPtr drmModeGetFB(int fd, uint32_t bufferId); +extern drmModeFB2Ptr drmModeGetFB2(int fd, uint32_t bufferId); /** * Creates a new framebuffer with an buffer object as its scanout buffer.
