From 707b6e3d3cfaf8e6a3a4f2c381e0b354848771c2 Mon Sep 17 00:00:00 2001 From: Deepak S Date: Fri, 16 Jan 2015 20:42:17 +0530 Subject: [PATCH] drm/i915: Increase the range of sideband address. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Looks like latest BSW/CHV production system has sideband address > 128. Use u32 data types to cover new offset/address range :) Signed-off-by: Deepak S Reviewed-by: Ville Syrjälä Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_drv.h | 4 ++-- drivers/gpu/drm/i915/intel_sideband.c | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 100f1ff3563c..b5616471f45d 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -3131,8 +3131,8 @@ int sandybridge_pcode_read(struct drm_i915_private *dev_priv, u32 mbox, u32 *val int sandybridge_pcode_write(struct drm_i915_private *dev_priv, u32 mbox, u32 val); /* intel_sideband.c */ -u32 vlv_punit_read(struct drm_i915_private *dev_priv, u8 addr); -void vlv_punit_write(struct drm_i915_private *dev_priv, u8 addr, u32 val); +u32 vlv_punit_read(struct drm_i915_private *dev_priv, u32 addr); +void vlv_punit_write(struct drm_i915_private *dev_priv, u32 addr, u32 val); u32 vlv_nc_read(struct drm_i915_private *dev_priv, u8 addr); u32 vlv_gpio_nc_read(struct drm_i915_private *dev_priv, u32 reg); void vlv_gpio_nc_write(struct drm_i915_private *dev_priv, u32 reg, u32 val); diff --git a/drivers/gpu/drm/i915/intel_sideband.c b/drivers/gpu/drm/i915/intel_sideband.c index 01d841ea3140..3c42eeffa3cb 100644 --- a/drivers/gpu/drm/i915/intel_sideband.c +++ b/drivers/gpu/drm/i915/intel_sideband.c @@ -75,7 +75,7 @@ static int vlv_sideband_rw(struct drm_i915_private *dev_priv, u32 devfn, return 0; } -u32 vlv_punit_read(struct drm_i915_private *dev_priv, u8 addr) +u32 vlv_punit_read(struct drm_i915_private *dev_priv, u32 addr) { u32 val = 0; @@ -89,7 +89,7 @@ u32 vlv_punit_read(struct drm_i915_private *dev_priv, u8 addr) return val; } -void vlv_punit_write(struct drm_i915_private *dev_priv, u8 addr, u32 val) +void vlv_punit_write(struct drm_i915_private *dev_priv, u32 addr, u32 val) { WARN_ON(!mutex_is_locked(&dev_priv->rps.hw_lock)); -- GitLab
