drm/i915: Initialize dkl_phy spin lock from display code path Start moving the initialization of display locks from i915_driver_early_probe(). Display locks should be initialized from display-only code paths. It was also agreed that if a variable is only used in one file, it should be initialized only in that file, so intel_dkl_phy_init() was added. v2: - added intel_display_locks_init() v3: - rebased v4: - dropped intel_display_locks_init() v5: - moved intel_dkl_phy_init() to the beginning of file Cc: intel-gfx@xxxxxxxxxxxxxxxxxxxxx Cc: Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx> Cc: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Cc: Jani Nikula <jani.nikula@xxxxxxxxx> Cc: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx> Reviewed-by: Lucas De Marchi <lucas.demarchi@xxxxxxxxx> Signed-off-by: José Roberto de Souza <jose.souza@xxxxxxxxx> Link: https://patchwork.freedesktop.org/patch/msgid/20230420170558.35398-1-jose.souza@xxxxxxxxx (cherry picked from commit bfa010f608491036327db20aad1d15e28da0189e) --- drivers/gpu/drm/i915/display/intel_display_driver.c | 2 ++ drivers/gpu/drm/i915/display/intel_dkl_phy.c | 9 +++++++++ drivers/gpu/drm/i915/display/intel_dkl_phy.h | 1 + drivers/gpu/drm/i915/i915_driver.c | 1 - 4 files changed, 12 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/display/intel_display_driver.c b/drivers/gpu/drm/i915/display/intel_display_driver.c index 92c624f6d2ae7..95669ad1a7975 100644 --- a/drivers/gpu/drm/i915/display/intel_display_driver.c +++ b/drivers/gpu/drm/i915/display/intel_display_driver.c @@ -30,6 +30,7 @@ #include "intel_display_driver.h" #include "intel_display_power.h" #include "intel_display_types.h" +#include "intel_dkl_phy.h" #include "intel_dmc.h" #include "intel_dp.h" #include "intel_dpll.h" @@ -177,6 +178,7 @@ void intel_display_driver_early_probe(struct drm_i915_private *i915) if (!HAS_DISPLAY(i915)) return; + intel_dkl_phy_init(i915); intel_color_init_hooks(i915); intel_init_cdclk_hooks(i915); intel_audio_hooks_init(i915); diff --git a/drivers/gpu/drm/i915/display/intel_dkl_phy.c b/drivers/gpu/drm/i915/display/intel_dkl_phy.c index 57cc3edba0163..a001232ad445e 100644 --- a/drivers/gpu/drm/i915/display/intel_dkl_phy.c +++ b/drivers/gpu/drm/i915/display/intel_dkl_phy.c @@ -11,6 +11,15 @@ #include "intel_dkl_phy.h" #include "intel_dkl_phy_regs.h" +/** + * intel_dkl_phy_init - initialize Dekel PHY + * @i915: i915 device instance + */ +void intel_dkl_phy_init(struct drm_i915_private *i915) +{ + spin_lock_init(&i915->display.dkl.phy_lock); +} + static void dkl_phy_set_hip_idx(struct drm_i915_private *i915, struct intel_dkl_phy_reg reg) { diff --git a/drivers/gpu/drm/i915/display/intel_dkl_phy.h b/drivers/gpu/drm/i915/display/intel_dkl_phy.h index 570ee36f9386f..5956ec3e940b1 100644 --- a/drivers/gpu/drm/i915/display/intel_dkl_phy.h +++ b/drivers/gpu/drm/i915/display/intel_dkl_phy.h @@ -12,6 +12,7 @@ struct drm_i915_private; +void intel_dkl_phy_init(struct drm_i915_private *i915); u32 intel_dkl_phy_read(struct drm_i915_private *i915, struct intel_dkl_phy_reg reg); void diff --git a/drivers/gpu/drm/i915/i915_driver.c b/drivers/gpu/drm/i915/i915_driver.c index decaff25c36cf..a4e11a3c1842f 100644 --- a/drivers/gpu/drm/i915/i915_driver.c +++ b/drivers/gpu/drm/i915/i915_driver.c @@ -225,7 +225,6 @@ static int i915_driver_early_probe(struct drm_i915_private *dev_priv) mutex_init(&dev_priv->display.wm.wm_mutex); mutex_init(&dev_priv->display.pps.mutex); mutex_init(&dev_priv->display.hdcp.comp_mutex); - spin_lock_init(&dev_priv->display.dkl.phy_lock); i915_memcpy_init_early(dev_priv); intel_runtime_pm_init_early(&dev_priv->runtime_pm); -- 2.40.0
