From 22d3fd4600fcb3da3df63157234a241485b58157 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Fri, 7 Feb 2014 19:12:49 +0000 Subject: [PATCH] drm/i915: Move num_plane to the intel_device_info structure MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit And rename it to num_sprites as this value doesn't count the primary plane. This limit lives with num_pipes really, and now that dev_priv->info is writable we can put it there instead. While at it, introduce a intel_device_info_runtime_init() where we'll be able to gather the device info fields at run-time. v2: rename num_plane to num_sprites (Ville Syrjälä) v3: rebase on top of latest drm-nightly Reviewed-by: Mika Kuoppala (for v2) Reviewed-by: Ville Syrjälä (for v2) Signed-off-by: Damien Lespiau Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_dma.c | 23 ++++++++++++++++++++--- drivers/gpu/drm/i915/i915_drv.h | 5 ++--- drivers/gpu/drm/i915/intel_display.c | 4 ++-- 3 files changed, 24 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_dma.c b/drivers/gpu/drm/i915/i915_dma.c index 0a9d0adc5a63..e281298c6fd5 100644 --- a/drivers/gpu/drm/i915/i915_dma.c +++ b/drivers/gpu/drm/i915/i915_dma.c @@ -1459,6 +1459,25 @@ static void i915_dump_device_info(struct drm_i915_private *dev_priv) #undef SEP_COMMA } +/* + * Determine various intel_device_info fields at runtime. + * + * Use it when either: + * - it's judged too laborious to fill n static structures with the limit + * when a simple if statement does the job, + * - run-time checks (eg read fuse/strap registers) are needed. + */ +static void intel_device_info_runtime_init(struct drm_device *dev) +{ + struct intel_device_info *info; + + info = (struct intel_device_info *)&to_i915(dev)->info; + + info->num_sprites = 1; + if (IS_VALLEYVIEW(dev)) + info->num_sprites = 2; +} + /** * i915_driver_load - setup chip and create an initial config * @dev: DRM device @@ -1638,9 +1657,7 @@ int i915_driver_load(struct drm_device *dev, unsigned long flags) if (!IS_I945G(dev) && !IS_I945GM(dev)) pci_enable_msi(dev->pdev); - dev_priv->num_plane = 1; - if (IS_VALLEYVIEW(dev)) - dev_priv->num_plane = 2; + intel_device_info_runtime_init(dev); if (INTEL_INFO(dev)->num_pipes) { ret = drm_vblank_init(dev, INTEL_INFO(dev)->num_pipes); diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index f66699f1ba11..36ea18999dee 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -79,7 +79,7 @@ enum plane { }; #define plane_name(p) ((p) + 'A') -#define sprite_name(p, s) ((p) * dev_priv->num_plane + (s) + 'A') +#define sprite_name(p, s) ((p) * INTEL_INFO(dev)->num_sprites + (s) + 'A') enum port { PORT_A = 0, @@ -530,6 +530,7 @@ struct intel_uncore { struct intel_device_info { u32 display_mmio_offset; u8 num_pipes:3; + u8 num_sprites:2; u8 gen; u8 ring_mask; /* Rings supported by the HW */ DEV_INFO_FOR_EACH_FLAG(DEFINE_FLAG, SEP_SEMICOLON); @@ -1450,8 +1451,6 @@ typedef struct drm_i915_private { u32 hpd_event_bits; struct timer_list hotplug_reenable_timer; - int num_plane; - struct i915_fbc fbc; struct intel_opregion opregion; struct intel_vbt_data vbt; diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 1ad59d73e7d6..c2686d7d2efc 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -1189,7 +1189,7 @@ static void assert_sprites_disabled(struct drm_i915_private *dev_priv, u32 val; if (IS_VALLEYVIEW(dev)) { - for (i = 0; i < dev_priv->num_plane; i++) { + for (i = 0; i < INTEL_INFO(dev)->num_sprites; i++) { reg = SPCNTR(pipe, i); val = I915_READ(reg); WARN((val & SP_ENABLE), @@ -11038,7 +11038,7 @@ void intel_modeset_init(struct drm_device *dev) for_each_pipe(i) { intel_crtc_init(dev, i); - for (j = 0; j < dev_priv->num_plane; j++) { + for (j = 0; j < INTEL_INFO(dev)->num_sprites; j++) { ret = intel_plane_init(dev, i, j); if (ret) DRM_DEBUG_KMS("pipe %c sprite %c init failed: %d\n", -- 2.20.1
