From 945b18fb4803b01e822ade6aef6cc0b6e4bd644f Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Thu, 1 Oct 2020 01:36:42 +0300 Subject: drm/i915: Fix TGL DKL PHY DP vswing handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The HDMI vs. not-HDMI check got inverted whem the bogus encoder->type checks were eliminated. So now we're using 0 as the link rate on DP and potentially non-zero on HDMI, which is exactly the opposite of what we want. The original bogus check actually worked more correctly by accident since if would always evaluate to true. Due to this we now always use the RBR/HBR1 vswing table and never ever the HBR2+ vswing table. That is probably not a good way to get a high quality signal at HBR2+ rates. Fix the check so we pick the right table.

charset=UTF-8 Content-Transfer-Encoding: 8bit Now that we've plumbed the crtc state all the way down we can eliminate the DP_TP_{CTL,STATUS} register offsets from intel_dp, and instead we derive them directly from the crtc state. And thus we can get rid of the nasty hack in intel_ddi_get_config() which mutates intel_dp during the readout.

Consilidate lspcon_init() into lspcon_resume() to dynamically init lspcon chip, and make HDMI port work. v6: - Rebase on latest for-linux-next. v5: - Consolidate lspcon_resume() with lspcon_init(). - Move more logic into lspcon code. v4: - Trust VBT in intel_infoframe_init(). - Init lspcon in intel_dp_detect(). v3: - Make sure it's handled under long HPD case. v2: - Move lspcon_init() inside of intel_dp_hpd_pulse().

charset=UTF-8 Content-Transfer-Encoding: 8bit Atm, if a full modeset is performed during the initial modeset the link training will happen with uninitialized max DP rate and lane count. Make sure the corresponding encoder state is initialized by adding an encoder hook called during driver init and system resume. A better alternative would be to store all states in the CRTC state and make this state available for the link re-training code. Also instead of the DPCD read in the hook there should be really a proper sink HW readout in place. Both of these require a bigger rework, so for now opting for this minimal fix to make at least full initial modesets work. The patch is based on https://patchwork.freedesktop.org/patch/101473/?series=10354&rev=3 v2: (Ville) - s/sanitize_state/sync_state/ - No point in calling the hook when CRTC is disabled, remove the call. - No point in calling the hook for MST, remove it. v3: Check only DPCD_REV to avoid clobbering intel_dp->dpcd.

Hide this behind a single macro that chooses the correct register according to the phy being accessed, use the correct bitfields for each pll/phy and implement separate functions for DG1 since it doesn't share much with ICL/TGL anymore. The previous values were correct for PHY A and B since they were using the same register as before and the bitfields were matching. v2: Add comment and try to simplify DG1_DPCLKA* macros by reusing previous ones v3: - Fix DG1_DPCLKA_CFGCR0_DDI_CLK_SEL_MASK() after wrong macro reuse - Move phy -> id map to a separate macro (Aditya) - Remove DG1_DPCLKA_CFGCR0_DDI_CLK_SEL_MASK where not required (Aditya) - Use drm_WARN_ON Cc: José Roberto de Souza Cc: Clinton Taylor Cc: Matt Roper Cc: Aditya Swarup Signed-off-by: Lucas De Marchi Reviewed-by: Aditya Swarup Link: https://patchwork.freedesktop.org/patch/msgid/20201106210006.837953-1-lucas.demarchi@intel.com --- drivers/gpu/drm/i915/display/intel_ddi.c | 91 +++++++++++++++++++++++++++- drivers/gpu/drm/i915/display/intel_display.c | 24 +++++++- drivers/gpu/drm/i915/i915_reg.h | 24 ++++++++ 3 files changed, 135 insertions(+), 4 deletions(-) (limited to 'drivers/gpu/drm/i915/display/intel_ddi.c') diff --git a/drivers/gpu/drm/i915/display/intel_ddi.c b/drivers/gpu/drm/i915/display/intel_ddi.c index 19b16517a502..36a4a1f4d775 100644 --- a/drivers/gpu/drm/i915/display/intel_ddi.c +++ b/drivers/gpu/drm/i915/display/intel_ddi.c @@ -2970,6 +2970,40 @@ static u32 icl_dpclka_cfgcr0_clk_off(struct drm_i915_private *dev_priv, return 0; } +static void dg1_map_plls_to_ports(struct intel_encoder *encoder, + const struct intel_crtc_state *crtc_state) +{ + struct drm_i915_private *dev_priv = to_i915(encoder->base.dev); + struct intel_shared_dpll *pll = crtc_state->shared_dpll; + enum phy phy = intel_port_to_phy(dev_priv, encoder->port); + u32 val; + + /* + * If we fail this, something went very wrong: first 2 PLLs should be + * used by first 2 phys and last 2 PLLs by last phys + */ + if (drm_WARN_ON(&dev_priv->drm, + (pll->info->id < DPLL_ID_DG1_DPLL2 && phy >= PHY_C) || + (pll->info->id >= DPLL_ID_DG1_DPLL2 && phy < PHY_C))) + return; + + mutex_lock(&dev_priv->dpll.lock); + + val = intel_de_read(dev_priv, DG1_DPCLKA_CFGCR0(phy)); + drm_WARN_ON(&dev_priv->drm, + (val & DG1_DPCLKA_CFGCR0_DDI_CLK_OFF(phy)) == 0); + + val &= ~DG1_DPCLKA_CFGCR0_DDI_CLK_SEL_MASK(phy); + val |= DG1_DPCLKA_CFGCR0_DDI_CLK_SEL(pll->info->id, phy); + intel_de_write(dev_priv, DG1_DPCLKA_CFGCR0(phy), val); + intel_de_posting_read(dev_priv, DG1_DPCLKA_CFGCR0(phy)); + + val &= ~DG1_DPCLKA_CFGCR0_DDI_CLK_OFF(phy); + intel_de_write(dev_priv, DG1_DPCLKA_CFGCR0(phy), val); + + mutex_unlock(&dev_priv->dpll.lock); +} + static void icl_map_plls_to_ports(struct intel_encoder *encoder, const struct intel_crtc_state *crtc_state) { @@ -3017,6 +3051,19 @@ static void icl_map_plls_to_ports(struct intel_encoder *encoder, mutex_unlock(&dev_priv->dpll.lock); } +static void dg1_unmap_plls_to_ports(struct intel_encoder *encoder) +{ + struct drm_i915_private *dev_priv = to_i915(encoder->base.dev); + enum phy phy = intel_port_to_phy(dev_priv, encoder->port); + + mutex_lock(&dev_priv->dpll.lock); + + intel_de_rmw(dev_priv, DG1_DPCLKA_CFGCR0(phy), 0, + DG1_DPCLKA_CFGCR0_DDI_CLK_OFF(phy)); + + mutex_unlock(&dev_priv->dpll.lock); +} + static void icl_unmap_plls_to_ports(struct intel_encoder *encoder) { struct drm_i915_private *dev_priv = to_i915(encoder->base.dev); @@ -3032,6 +3079,37 @@ static void icl_unmap_plls_to_ports(struct intel_encoder *encoder) mutex_unlock(&dev_priv->dpll.lock); } +static void dg1_sanitize_port_clk_off(struct drm_i915_private *dev_priv, + u32 port_mask, bool ddi_clk_needed) +{ + enum port port; + u32 val; + + for_each_port_masked(port, port_mask) { + enum phy phy = intel_port_to_phy(dev_priv, port); + bool ddi_clk_off; + + val = intel_de_read(dev_priv, DG1_DPCLKA_CFGCR0(phy)); + ddi_clk_off = val & DG1_DPCLKA_CFGCR0_DDI_CLK_OFF(phy); + + if (ddi_clk_needed == !ddi_clk_off) + continue; + + /* + * Punt on the case now where clock is gated, but it would + * be needed by the port.

charset=UTF-8 Content-Transfer-Encoding: 8bit Currently the DPLL .get_freq() uses pll->state.hw_state which is not the thing we actually read out (except during driver load/resume). Outside of that pll->state.hw_state is just the thing we committed last time around. During state check we just read the thing into crtc_state->dpll_hw_state, so that is what we should use for calculating the DPLL output frequency. I think we used to do this so that the results of the readout were actually used, but somehow it got changed when the .get_freq() refactoring happened.

Ideally the end user never notices the second pipe is used. This way ideally everything will be tear free, and updates are really atomic as userspace expects it. This uses generic modeset_enables() calls like trans port sync but still has special handling for disable since for slave we should not disable things like encoder, plls that are not enabled for slave.
