From d31c85fc864269ab8e6fb6ed36c87f2fc33a9430 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 13 Feb 2019 15:21:09 +0000 Subject: snd/hda, drm/i915: Track the display_power_status using a cookie drm/i915 is tracking all wakeref owners with a cookie in order to identify leaks. To that end, each rpm acquisition ops->get_power is assigned a cookie which should be passed to ops->put_power to signify its release (and removal from the list of wakeref owners). As snd/hda is already using a bool to track current status of display_power extending that to an unsigned long to hold the boolean cookie is a trivial extension, and will quell all doubt that snd/hda is the cause of the device runtime pm leaks. v2: Keep using the power abstraction for local wakeref tracking. v3: BUILD_BUG_ON impedance mismatch Signed-off-by: Chris Wilson Cc: Takashi Iwai Cc: Jani Nikula Acked-by: Takashi Iwai Reviewed-by: Mika Kuoppala Link: https://patchwork.freedesktop.org/patch/msgid/20190213152109.16997-1-chris@chris-wilson.co.uk --- include/drm/drm_audio_component.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'include/drm') diff --git a/include/drm/drm_audio_component.h b/include/drm/drm_audio_component.h index 4923b00328c1..d0c7444319f5 100644 --- a/include/drm/drm_audio_component.h +++ b/include/drm/drm_audio_component.h @@ -18,14 +18,17 @@ struct drm_audio_component_ops { * @get_power: get the POWER_DOMAIN_AUDIO power well * * Request the power well to be turned on. + * + * Returns a wakeref cookie to be passed back to the corresponding + * call to @put_power. */ - void (*get_power)(struct device *); + unsigned long (*get_power)(struct device *); /** * @put_power: put the POWER_DOMAIN_AUDIO power well * * Allow the power well to be turned off. */ - void (*put_power)(struct device *); + void (*put_power)(struct device *, unsigned long); /** * @codec_wake_override: Enable/disable codec wake signal */ -- cgit v1.3-18-gd494 From 8605a1366015afb0ec7dd486262d0b4088e3c75f Mon Sep 17 00:00:00 2001 From: Ramalingam C Date: Fri, 15 Feb 2019 14:04:57 +0530 Subject: drm/i915: enum port definition is moved into i915_drm.h For the reusability of the enum port in other driver modules (like mei_hdcp), enum port definition is moved from I915 local header intel_display.h to drm/i915_drm.h Signed-off-by: Ramalingam C Acked-by: Daniel Vetter [danvet: Fix subject prefix.] Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/1550219730-17734-3-git-send-email-ramalingam.c@intel.com --- drivers/gpu/drm/i915/intel_display.h | 16 +--------------- include/drm/i915_drm.h | 15 +++++++++++++++ 2 files changed, 16 insertions(+), 15 deletions(-) (limited to 'include/drm') diff --git a/drivers/gpu/drm/i915/intel_display.h b/drivers/gpu/drm/i915/intel_display.h index 4262452963b3..79203666fc62 100644 --- a/drivers/gpu/drm/i915/intel_display.h +++ b/drivers/gpu/drm/i915/intel_display.h @@ -26,6 +26,7 @@ #define _INTEL_DISPLAY_H_ #include +#include enum i915_gpio { GPIOA, @@ -150,21 +151,6 @@ enum plane_id { for ((__p) = PLANE_PRIMARY; (__p) < I915_MAX_PLANES; (__p)++) \ for_each_if((__crtc)->plane_ids_mask & BIT(__p)) -enum port { - PORT_NONE = -1, - - PORT_A = 0, - PORT_B, - PORT_C, - PORT_D, - PORT_E, - PORT_F, - - I915_MAX_PORTS -}; - -#define port_name(p) ((p) + 'A') - /* * Ports identifier referenced from other drivers. * Expected to remain stable over time diff --git a/include/drm/i915_drm.h b/include/drm/i915_drm.h index c44703f471b3..7523e9a7b6e2 100644 --- a/include/drm/i915_drm.h +++ b/include/drm/i915_drm.h @@ -100,4 +100,19 @@ extern struct resource intel_graphics_stolen_res; #define INTEL_GEN11_BSM_DW1 0xc4 #define INTEL_BSM_MASK (-(1u << 20)) +enum port { + PORT_NONE = -1, + + PORT_A = 0, + PORT_B, + PORT_C, + PORT_D, + PORT_E, + PORT_F, + + I915_MAX_PORTS +}; + +#define port_name(p) ((p) + 'A') + #endif /* _I915_DRM_H_ */ -- cgit v1.3-18-gd494 From 1626eab70ebc61d015e69a4bc3479d9228539343 Mon Sep 17 00:00:00 2001 From: Ramalingam C Date: Fri, 15 Feb 2019 14:04:58 +0530 Subject: drm/i915: header for i915 - MEI_HDCP interface Header defines the interface for the I915 and MEI_HDCP drivers.

They are however used in some drivers to define on which pixel clock edge data and sync signals are sampled, which should usually (but not always) be the opposite edge of the driving edge. This creates confusion. Create four new macros for both PIXDATA and SYNC that explicitly state the driving and sampling edge in their name to remove the confusion. The driving macros are defined as the opposite of the sampling macros to made code simpler based on the assumption that the driving and sampling edges are opposite.

Replace them through the code. This effectively changes the value of the .sampling_edge bridge timings field in the dumb-vga-dac driver. This is safe to do as no driver consumes these values yet.

Add two new optional connector helper operations, .prepare_writeback_job() and .cleanup_writeback_job() to support this. The job prepare operation is called from drm_atomic_helper_prepare_planes() to avoid a new atomic commit helper that would need to be called by all drivers not using drm_atomic_helper_commit(). The job cleanup operation is called from the existing drm_writeback_cleanup_job() function, invoked both when destroying the job as part of a aborted commit, or when the job completes. The drm_writeback_job structure is extended with a priv field to let drivers store per-job data, such as mappings related to the writeback framebuffer. For internal plumbing reasons the drm_writeback_job structure needs to store a back-pointer to the drm_writeback_connector. To avoid pushing too much writeback-specific knowledge to drm_atomic_uapi.c, create a drm_writeback_set_fb() function, move the writeback job setup code there, and set the connector backpointer. The prepare_signaling() function doesn't need to allocate writeback jobs and can ignore connectors without a job, as it is called after the writeback jobs are allocated to store framebuffers, and a writeback fence with a framebuffer is an invalid configuration that gets rejected by the commit check.
