This is currently enabled via a separate address resource, which needs to be specified in the devicetree. The address resource is required because on some SoCs, such as RK3288, the LUT address is after the MMU address, and the latter is supported by a different driver. This prevents the DRM driver from requesting an entire register space. The current implementation works for RGB 10-bit tables, as that is what seems to work on RK3288. Signed-off-by: Ezequiel Garcia --- Changes from v3: * Move to atomic_enable and atomic_begin, as discussed with Sean Paul. * Dropped the Reviewed-bys. Changes from v2: * None. Changes from v1: * drop explicit linear LUT after finding a proper way to disable gamma correction. * avoid setting gamma is the CRTC is not active. * s/int/unsigned int as suggested by Jacopo. * only enable color management and set gamma size if gamma LUT is supported, suggested by Doug. * drop the reg-names usage, and instead just use indexed reg specifiers, suggested by Doug. Changes from RFC: * Request (an optional) address resource for the LUT. * Drop support for RK3399, which doesn't seem to work out of the box and needs more research. * Support pass-thru setting when GAMMA_LUT is NULL. * Add a check for the gamma size, as suggested by Ilia. * Move gamma setting to atomic_commit_tail, as pointed out by Jacopo/Laurent, is the correct way. --- drivers/gpu/drm/rockchip/rockchip_drm_fb.c | 1 + drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 125 ++++++++++++++++++++ drivers/gpu/drm/rockchip/rockchip_drm_vop.h | 5 + drivers/gpu/drm/rockchip/rockchip_vop_reg.c | 2 + 4 files changed, 133 insertions(+) diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_fb.c b/drivers/gpu/drm/rockchip/rockchip_drm_fb.c index ca01234c037c..697ee04b85cf 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_fb.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_fb.c @@ -17,6 +17,7 @@ #include "rockchip_drm_drv.h" #include "rockchip_drm_fb.h" #include "rockchip_drm_gem.h" +#include "rockchip_drm_vop.h" static const struct drm_framebuffer_funcs rockchip_drm_fb_funcs = { .destroy = drm_gem_fb_destroy, diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_vop.c b/drivers/gpu/drm/rockchip/rockchip_drm_vop.c index 613404f86668..85c1269a1218 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_vop.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_vop.c @@ -139,6 +139,7 @@ struct vop { uint32_t *regsbak; void __iomem *regs; + void __iomem *lut_regs; /* physical map length of vop register */ uint32_t len; @@ -1048,6 +1049,84 @@ static bool vop_crtc_mode_fixup(struct drm_crtc *crtc, return true; } +static bool vop_dsp_lut_is_enable(struct vop *vop) +{ + return vop_read_reg(vop, 0, &vop->data->common->dsp_lut_en); +} + +static void vop_crtc_write_gamma_lut(struct vop *vop, struct drm_crtc *crtc) +{ + struct drm_color_lut *lut = crtc->state->gamma_lut->data; + unsigned int i; + + for (i = 0; i < crtc->gamma_size; i++) { + u32 word; + + word = (drm_color_lut_extract(lut[i].red, 10) << 20) | + (drm_color_lut_extract(lut[i].green, 10) << 10) | + drm_color_lut_extract(lut[i].blue, 10); + writel(word, vop->lut_regs + i * 4); + } +} + +static void vop_crtc_gamma_set(struct vop *vop, struct drm_crtc *crtc, + struct drm_crtc_state *old_crtc_state) +{ + unsigned int idle; + int ret; + + /* + * In order to write the LUT to the internal memory, + * we need to first make sure the dsp_lut_en bit is cleared. + */ + spin_lock(&vop->reg_lock); + VOP_REG_SET(vop, common, dsp_lut_en, 0); + vop_cfg_done(vop); + spin_unlock(&vop->reg_lock); + + /* + * If the CRTC is not active, dsp_lut_en will not get cleared. + * Apparently we still need to do the above step to for + * gamma correction to be disabled. + */ + if (!crtc->state->active) + return; + + ret = readx_poll_timeout(vop_dsp_lut_is_enable, vop, + idle, !idle, 5, 30 * 1000); + if (ret) { + DRM_DEV_ERROR(vop->dev, "display LUT RAM enable timeout!\n"); + return; + } + + if (crtc->state->gamma_lut && + (!old_crtc_state->gamma_lut || (crtc->state->gamma_lut->base.id != + old_crtc_state->gamma_lut->base.id))) { + + spin_lock(&vop->reg_lock); + + vop_crtc_write_gamma_lut(vop, crtc); + VOP_REG_SET(vop, common, dsp_lut_en, 1); + vop_cfg_done(vop); + + spin_unlock(&vop->reg_lock); + } +} + +static void vop_crtc_atomic_begin(struct drm_crtc *crtc, + struct drm_crtc_state *old_crtc_state) +{ + struct vop *vop = to_vop(crtc); + + /* + * Only update GAMMA if the 'active' flag is not changed, + * otherwise it's updated by .atomic_enable. + */ + if (vop->lut_regs && crtc->state->color_mgmt_changed && + !crtc->state->active_changed) + vop_crtc_gamma_set(vop, crtc, old_crtc_state); +} + static void vop_crtc_atomic_enable(struct drm_crtc *crtc, struct drm_crtc_state *old_state) { @@ -1075,6 +1154,14 @@ static void vop_crtc_atomic_enable(struct drm_crtc *crtc, return; } + /* + * If we have a GAMMA LUT in the state, then let's make sure + * it's updated.
