[PATCH v3 00/16] drm/tegra: Fix IOVA space on Tegra186 and later
by Thierry Reding 01 Feb '19

01 Feb '19

From: Thierry Reding <treding(a)nvidia.com> Tegra186 and later are different from earlier generations in that they use an ARM SMMU rather than the Tegra SMMU. The ARM SMMU driver behaves slightly differently in that the geometry for IOMMU domains is set only after a device was attached to it. This is to make sure that the SMMU instance that the domain belongs to is known, because each instance can have a different input address space (i.e. geometry). Work around this by moving all IOVA allocations to a point where the geometry of the domain is properly initialized. This second version of the series addresses all review comments and adds a number of patches that will actually allow host1x to work with an SMMU enabled on Tegra186. The patches also add programming required to address the full 40 bits of address space. The third version of the series fixes the 40-bit addressing code by making sure that wide opcodes are always written atomically to the push buffer. Another pair of patches are introduced to fix a long-standing bug where the HOST1X_CHANNEL_DMAEND register wasn't properly programmed and one push buffer memory optimization that avoid wasting almost one full memory page per push buffer. This supersedes the following patch: https://patchwork.kernel.org/patch/10775579/ Thierry Thierry Reding (16): gpu: host1x: Set up stream ID table gpu: host1x: Program the channel stream ID gpu: host1x: Introduce support for wide opcodes gpu: host1x: Support 40-bit addressing gpu: host1x: Use direct DMA with IOMMU API usage gpu: host1x: Restrict IOVA space to DMA mask gpu: host1x: Support 40-bit addressing on Tegra186 gpu: host1x: Use correct semantics for HOST1X_CHANNEL_DMAEND gpu: host1x: Optimize CDMA push buffer memory usage drm/tegra: Store parent pointer in Tegra DRM clients drm/tegra: vic: Load firmware on demand drm/tegra: Setup shared IOMMU domain after initialization drm/tegra: Restrict IOVA space to DMA mask drm/tegra: vic: Do not clear driver data drm/tegra: vic: Support stream ID register programming arm64: tegra: Enable SMMU for VIC on Tegra186 arch/arm64/boot/dts/nvidia/tegra186.dtsi | 1 + drivers/gpu/drm/tegra/drm.c | 57 +++++---- drivers/gpu/drm/tegra/drm.h | 1 + drivers/gpu/drm/tegra/vic.c | 75 ++++++++--- drivers/gpu/drm/tegra/vic.h | 9 ++ drivers/gpu/host1x/cdma.c | 132 ++++++++++++++++++-- drivers/gpu/host1x/cdma.h | 2 + drivers/gpu/host1x/dev.c | 49 +++++++- drivers/gpu/host1x/dev.h | 8 ++ drivers/gpu/host1x/hw/cdma_hw.c | 32 ++++- drivers/gpu/host1x/hw/channel_hw.c | 42 ++++++- drivers/gpu/host1x/hw/host1x06_hardware.h | 6 + drivers/gpu/host1x/hw/host1x07_hardware.h | 6 + drivers/gpu/host1x/hw/hw_host1x06_channel.h | 11 ++ drivers/gpu/host1x/hw/hw_host1x07_channel.h | 11 ++ include/trace/events/host1x.h | 26 ++++ 16 files changed, 404 insertions(+), 64 deletions(-) create mode 100644 drivers/gpu/host1x/hw/hw_host1x06_channel.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x07_channel.h -- 2.19.1

From: Thierry Reding <treding(a)nvidia.com> The SOR has a crossbar that can map each lane of the SOR to each of the SOR pads. The mapping is usually the same across designs for a specific SoC generation, but every now and then there's a design that doesn't.

[PATCH] drm/sun4i: tcon: Prepare and enable TCON channel 0 clock at init
by Paul Kocialkowski 01 Feb '19

01 Feb '19

When initializing clocks, a reference to the TCON channel 0 clock is obtained. However, the clock is never prepared and enabled later. Switching from simplefb to DRM actually disables the clock (that was usually configured by U-Boot) because of that. On the V3s, this results in a hang when writing to some mixer registers when switching over to DRM from simplefb. Fix this by preparing and enabling the clock when initializing other clocks. Waiting for sun4i_tcon_channel_enable to enable the clock is apparently too late and results in the same mixer register access hang.

[PATCH 0/8] drm/meson: Add support for HDMI2.0 4k60
by Neil Armstrong 01 Feb '19

01 Feb '19

This patchset aims to add support for the following HDMI2.0 4k60 modes: - 594Mhz TMDS frequency needing TMDS Scramling and 1/40 rate for RGB/YUV4:4:4 - 297MHz TMDS frequency with YUV4:2:0 encoding The first mode uses the SCDC helpers introduced by intel to : - discover where the monitor support SCDC - setup the SCDC parameters This is implemented in the dw-hdmi bridge driver by handling scrambling support during the bridge setup and by exporting an helper for the PHY setup to setup the SCDC configuration for the 1/40 TMDS rate. This code will only be active if the encoder support a TMDS rate > 340MHz. This patch could eventually break support on different SoC when connected on a 4k60 monitor with SCDC : - i.MX correctly discards pixel clocks > 216MHz - R-CAR discards discards pixel clocks > 297MHz since [1] - Rockchip discards invalid pixel clocks not in the rockchip_mpll_cfg table - sun8i correctly discards pixel clocks > 297MHz on a83t - sun8i discards discards pixel clocks > 594Mhz on h6, which is already broken First patch should fix support for Allwinner H6. The second mode is implemented by added the missing 4:2:0 bypass handling in the dw-hdmi bridge driver and adding a "mtmdsclock" separating the pixel clock from the tmds clock in the mode setup phase. We also enable support for these modes in the connector only if the platform glue code explicits the support. Only the meson DRM dw_hdmi glue allows ycbcr420 modes, so no breakage is expected here. The remaining patches adds support for : - 1/40 TMDS rate aka DIV40 in the dw-hdmi meson PHY setup - 4:2:0 output and clock setup The dw-hdmi support re-uses the support done by Rockchip engineers on the Linux 4.4 BSP kernel. These modes has been validated using a MuxLab HDMI Signal Analyser in addition to different UHD TVs supporting full 4k60 or the 4:2:0 variant.

[PATCH] drm/i915: Enable fastboot by default on VLV and CHV
by Hans de Goede 01 Feb '19

01 Feb '19

We really want to have fastboot enabled by default to avoid an ugly modeset during boot. Currently we are enabling fastboot by default on gen9+ (Skylake and newer). The intention is to enable it on older generations after it has seen more testing on gen9+. VLV and CHV devices are still being sold in stores today, as such it is desirable to also enable fastboot by default on these now. I've extensively tested fastboot=1 support on over 50 different Bay- and Cherry-Trail devices. Testing DSI and eDP panels as well as HDMI output (and even DP over Type-C on one device). All 50 devices work fine with fastboot=1. On 2 devices their DSI panel turns black as soon as the i915 driver loads when fastboot=0, so having fastboot enabled is required for these 2 to work properly (for lack of a better fix).

[PATCH 0/2] RFC: Mixel DPHY support for i.MX8
by Guido Günther 01 Feb '19

01 Feb '19

This adds initial support for the Mixel IP based mipi dphy as found on i.MX8 processors. It has support for the i.MX8MQ, support for other variants can be added - once the necessary parts are in - via the provided hooks. The driver is somewhat based on what's found in NXPs BSP. Documentation on the DPHY's registers is currently thin in the i.MX8 reference manuals (even on the i.MX8QXP form 11/18) so most of the values were taken from existing drivers. This is based on linux-next as of 2019-01-21 and Maxime Ripard's dphy configuration helper patches which would need to go in first. To get DSI working on the imx8MQ there's a driver for the nwl dsi host controller missing which I intend to looking at too.
