From 10769d2bbd1f82f4a1ed62f5316d85d626a8840c Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Mon, 14 Apr 2014 20:24:26 +0300 Subject: [PATCH] drm/i915: remove the i915_dpio debugfs entry MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There are igt tools that can read/write the DPIO registers, so having a debugfs entry for only some of those registers is somewhat arbitrary / redundant. Remove it. v2: - instead of fixing the entry by taking a power domain reference around the register accesses, remove the entry (Ville) Signed-off-by: Imre Deak Reviewed-by: Ville Syrjälä Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_debugfs.c | 48 ----------------------------- 1 file changed, 48 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_debugfs.c b/drivers/gpu/drm/i915/i915_debugfs.c index 02f1b39fce36..4c785a26dceb 100644 --- a/drivers/gpu/drm/i915/i915_debugfs.c +++ b/drivers/gpu/drm/i915/i915_debugfs.c @@ -1903,53 +1903,6 @@ static int i915_ppgtt_info(struct seq_file *m, void *data) return 0; } -static int i915_dpio_info(struct seq_file *m, void *data) -{ - struct drm_info_node *node = (struct drm_info_node *) m->private; - struct drm_device *dev = node->minor->dev; - struct drm_i915_private *dev_priv = dev->dev_private; - int ret; - - - if (!IS_VALLEYVIEW(dev)) { - seq_puts(m, "unsupported\n"); - return 0; - } - - ret = mutex_lock_interruptible(&dev_priv->dpio_lock); - if (ret) - return ret; - - seq_printf(m, "DPIO_CTL: 0x%08x\n", I915_READ(DPIO_CTL)); - - seq_printf(m, "DPIO PLL DW3 CH0 : 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW3(0))); - seq_printf(m, "DPIO PLL DW3 CH1: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW3(1))); - - seq_printf(m, "DPIO PLL DW5 CH0: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW5(0))); - seq_printf(m, "DPIO PLL DW5 CH1: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW5(1))); - - seq_printf(m, "DPIO PLL DW7 CH0: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW7(0))); - seq_printf(m, "DPIO PLL DW7 CH1: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW7(1))); - - seq_printf(m, "DPIO PLL DW10 CH0: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW10(0))); - seq_printf(m, "DPIO PLL DW10 CH1: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_PLL_DW10(1))); - - seq_printf(m, "DPIO_FASTCLK_DISABLE: 0x%08x\n", - vlv_dpio_read(dev_priv, PIPE_A, VLV_CMN_DW0)); - - mutex_unlock(&dev_priv->dpio_lock); - - return 0; -} - static int i915_llc(struct seq_file *m, void *data) { struct drm_info_node *node = (struct drm_info_node *) m->private; @@ -3808,7 +3761,6 @@ static const struct drm_info_list i915_debugfs_list[] = { {"i915_gen6_forcewake_count", i915_gen6_forcewake_count_info, 0}, {"i915_swizzle_info", i915_swizzle_info, 0}, {"i915_ppgtt_info", i915_ppgtt_info, 0}, - {"i915_dpio", i915_dpio_info, 0}, {"i915_llc", i915_llc, 0}, {"i915_edp_psr_status", i915_edp_psr_status, 0}, {"i915_sink_crc_eDP1", i915_sink_crc, 0}, -- 2.39.5
