From 41016fe1028e4b0ee6f436f928564699898ec2b0 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 19 Feb 2021 13:00:28 +0100 Subject: drm: Rename plane->state variables in atomic update and disable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some drivers are storing the plane->state pointer in atomic_update and atomic_disable in a variable simply called state, while the state passed as an argument is called old_state. In order to ease subsequent reworks and to avoid confusing or inconsistent names, let's rename those variables to new_state. This was done using the following coccinelle script, plus some manual changes for mtk and tegra. @ plane_atomic_func @ identifier helpers; identifier func; @@ ( static const struct drm_plane_helper_funcs helpers = { ..., .atomic_disable = func, ..., }; | static const struct drm_plane_helper_funcs helpers = { ..., .atomic_update = func, ..., }; ) @ moves_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; symbol old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *new_state = plane->state; ... } @ depends on moves_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; identifier old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { <... - state + new_state ...> } @ moves_new_state_oldstate @ identifier plane_atomic_func.func; identifier plane; symbol oldstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *oldstate) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *newstate = plane->state; ... } @ depends on moves_new_state_oldstate @ identifier plane_atomic_func.func; identifier plane; identifier old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { <... - state + newstate ...> } @ moves_new_state_old_pstate @ identifier plane_atomic_func.func; identifier plane; symbol old_pstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_pstate) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *new_pstate = plane->state; ... } @ depends on moves_new_state_old_pstate @ identifier plane_atomic_func.func; identifier plane; identifier old_pstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_pstate) { <... - state + new_pstate ...> } Reviewed-by: Ville Syrjälä Signed-off-by: Maxime Ripard Acked-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20210219120032.260676-8-maxime@cerno.tech --- drivers/gpu/drm/stm/ltdc.c | 28 ++++++++++++++-------------- 1 file changed, 14 insertions(+), 14 deletions(-) (limited to 'drivers/gpu/drm/stm') diff --git a/drivers/gpu/drm/stm/ltdc.c b/drivers/gpu/drm/stm/ltdc.c index 83f4b2e7f8d1..3aa5bad8bbe4 100644 --- a/drivers/gpu/drm/stm/ltdc.c +++ b/drivers/gpu/drm/stm/ltdc.c @@ -778,33 +778,33 @@ static void ltdc_plane_atomic_update(struct drm_plane *plane, struct drm_plane_state *oldstate) { struct ltdc_device *ldev = plane_to_ltdc(plane); - struct drm_plane_state *state = plane->state; - struct drm_framebuffer *fb = state->fb; + struct drm_plane_state *newstate = plane->state; + struct drm_framebuffer *fb = newstate->fb; u32 lofs = plane->index * LAY_OFS; - u32 x0 = state->crtc_x; - u32 x1 = state->crtc_x + state->crtc_w - 1; - u32 y0 = state->crtc_y; - u32 y1 = state->crtc_y + state->crtc_h - 1; + u32 x0 = newstate->crtc_x; + u32 x1 = newstate->crtc_x + newstate->crtc_w - 1; + u32 y0 = newstate->crtc_y; + u32 y1 = newstate->crtc_y + newstate->crtc_h - 1; u32 src_x, src_y, src_w, src_h; u32 val, pitch_in_bytes, line_length, paddr, ahbp, avbp, bpcr; enum ltdc_pix_fmt pf; - if (!state->crtc || !fb) { + if (!newstate->crtc || !fb) { DRM_DEBUG_DRIVER("fb or crtc NULL"); return; } /* convert src_ from 16:16 format */ - src_x = state->src_x >> 16; - src_y = state->src_y >> 16; - src_w = state->src_w >> 16; - src_h = state->src_h >> 16; + src_x = newstate->src_x >> 16; + src_y = newstate->src_y >> 16; + src_w = newstate->src_w >> 16; + src_h = newstate->src_h >> 16; DRM_DEBUG_DRIVER("plane:%d fb:%d (%dx%d)@(%d,%d) -> (%dx%d)@(%d,%d)\n", plane->base.id, fb->base.id, src_w, src_h, src_x, src_y, - state->crtc_w, state->crtc_h, - state->crtc_x, state->crtc_y); + newstate->crtc_w, newstate->crtc_h, + newstate->crtc_x, newstate->crtc_y); bpcr = reg_read(ldev->regs, LTDC_BPCR); ahbp = (bpcr & BPCR_AHBP) >> 16; @@ -863,7 +863,7 @@ static void ltdc_plane_atomic_update(struct drm_plane *plane, reg_update_bits(ldev->regs, LTDC_L1CFBLNR + lofs, LXCFBLNR_CFBLN, val); /* Sets the FB address */ - paddr = (u32)drm_fb_cma_get_gem_addr(fb, state, 0); + paddr = (u32)drm_fb_cma_get_gem_addr(fb, newstate, 0); DRM_DEBUG_DRIVER("fb: phys 0x%08x", paddr); reg_write(ldev->regs, LTDC_L1CFBAR + lofs, paddr); -- cgit v1.2.3
