Changes Since V1: - move sources list per-crtc - init sources-list only for gen3 Changes Since V2: - Adopt to driver style - Address other review comments from Laurent Pinchart Signed-off-by: Mahesh Kumar Cc: dri-devel@lists.freedesktop.org Cc: Laurent Pinchart Reviewed-by: Laurent Pinchart --- drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 85 +++++++++++++++++++++++++++++++++- drivers/gpu/drm/rcar-du/rcar_du_crtc.h | 3 ++ 2 files changed, 87 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/rcar-du/rcar_du_crtc.c b/drivers/gpu/drm/rcar-du/rcar_du_crtc.c index 43e67cffdee0..39981ce422e1 100644 --- a/drivers/gpu/drm/rcar-du/rcar_du_crtc.c +++ b/drivers/gpu/drm/rcar-du/rcar_du_crtc.c @@ -691,6 +691,68 @@ static const struct drm_crtc_helper_funcs crtc_helper_funcs = { .atomic_disable = rcar_du_crtc_atomic_disable, }; +static void rcar_du_crtc_crc_sources_list_init(struct rcar_du_crtc *rcrtc) +{ + struct rcar_du_device *rcdu = rcrtc->group->dev; + const char **sources; + unsigned int count; + int i = -1; + + /* CRC available only on Gen3 HW. */ + if (rcdu->info->gen < 3) + return; + + /* Reserve 1 for "auto" source. */ + count = rcrtc->vsp->num_planes + 1; + + sources = kmalloc_array(count, sizeof(*sources), GFP_KERNEL); + if (!sources) + return; + + sources[0] = kstrdup("auto", GFP_KERNEL); + if (!sources[0]) + goto error; + + for (i = 0; i < rcrtc->vsp->num_planes; ++i) { + struct drm_plane *plane = &rcrtc->vsp->planes[i].plane; + char name[16]; + + sprintf(name, "plane%u", plane->base.id); + sources[i + 1] = kstrdup(name, GFP_KERNEL); + if (!sources[i + 1]) + goto error; + } + + rcrtc->sources = sources; + rcrtc->sources_count = count; + return; + +error: + while (i >= 0) { + kfree(sources[i]); + i--; + } + kfree(sources); + + rcrtc->sources = NULL; + rcrtc->sources_count = 0; +} + +static void rcar_du_crtc_crc_sources_list_uninit(struct rcar_du_crtc *rcrtc) +{ + unsigned int i; + + if (!rcrtc->sources) + return; + + for (i = 0; i < rcrtc->sources_count; i++) + kfree(rcrtc->sources[i]); + kfree(rcrtc->sources); + + rcrtc->sources = NULL; + rcrtc->sources_count = 0; +} + static struct drm_crtc_state * rcar_du_crtc_atomic_duplicate_state(struct drm_crtc *crtc) { @@ -717,6 +779,15 @@ static void rcar_du_crtc_atomic_destroy_state(struct drm_crtc *crtc, kfree(to_rcar_crtc_state(state)); } +static void rcar_du_crtc_cleanup(struct drm_crtc *crtc) +{ + struct rcar_du_crtc *rcrtc = to_rcar_crtc(crtc); + + rcar_du_crtc_crc_sources_list_uninit(rcrtc); + + return drm_crtc_cleanup(crtc); +} + static void rcar_du_crtc_reset(struct drm_crtc *crtc) { struct rcar_du_crtc_state *state; @@ -809,6 +880,15 @@ static int rcar_du_crtc_verify_crc_source(struct drm_crtc *crtc, return 0; } +const char *const *rcar_du_crtc_get_crc_sources(struct drm_crtc *crtc, + size_t *count) +{ + struct rcar_du_crtc *rcrtc = to_rcar_crtc(crtc); + + *count = rcrtc->sources_count; + return rcrtc->sources; +} + static int rcar_du_crtc_set_crc_source(struct drm_crtc *crtc, const char *source_name) { @@ -879,7 +959,7 @@ static const struct drm_crtc_funcs crtc_funcs_gen2 = { static const struct drm_crtc_funcs crtc_funcs_gen3 = { .reset = rcar_du_crtc_reset, - .destroy = drm_crtc_cleanup, + .destroy = rcar_du_crtc_cleanup, .set_config = drm_atomic_helper_set_config, .page_flip = drm_atomic_helper_page_flip, .atomic_duplicate_state = rcar_du_crtc_atomic_duplicate_state, @@ -888,6 +968,7 @@ static const struct drm_crtc_funcs crtc_funcs_gen3 = { .disable_vblank = rcar_du_crtc_disable_vblank, .set_crc_source = rcar_du_crtc_set_crc_source, .verify_crc_source = rcar_du_crtc_verify_crc_source, + .get_crc_sources = rcar_du_crtc_get_crc_sources, }; /* ----------------------------------------------------------------------------- @@ -1026,5 +1107,7 @@ int rcar_du_crtc_create(struct rcar_du_group *rgrp, unsigned int swindex, return ret; } + rcar_du_crtc_crc_sources_list_init(rcrtc); + return 0; } diff --git a/drivers/gpu/drm/rcar-du/rcar_du_crtc.h b/drivers/gpu/drm/rcar-du/rcar_du_crtc.h index 7680cb2636c8..592c79993e08 100644 --- a/drivers/gpu/drm/rcar-du/rcar_du_crtc.h +++ b/drivers/gpu/drm/rcar-du/rcar_du_crtc.h @@ -67,6 +67,9 @@ struct rcar_du_crtc { struct rcar_du_group *group; struct rcar_du_vsp *vsp; unsigned int vsp_pipe; + + const char *const *sources; + unsigned int sources_count; }; #define to_rcar_crtc(c) container_of(c, struct rcar_du_crtc, crtc)
