[PATCH] drm/i915: Mark GEM wedged right after marking device unplugged
by Janusz Krzysztofik 05 Apr '19

05 Apr '19

As soon as a device is considered unplugged, not only prevent pending users from accessing the device structures but also cancel all their pending requests so all consumed resources can be cleaned up as soon as possible.

[PATCH] drm/sun4i: DW HDMI: Lower max. supported rate for H6
by Jernej Skrabec 05 Apr '19

05 Apr '19

Currently resolutions with pixel clock higher than 340 MHz don't work with H6 HDMI controller. They just produce a blank screen. Limit maximum pixel clock rate to 340 MHz until scrambling is supported.

[PATCH 0/8] v4.19.0 Added Color Management Module
by VenkataRajesh.Kalakodima＠in.bosch.com 05 Apr '19

05 Apr '19

From: kalakodima venkata rajesh <venkatarajesh.kalakodima(a)in.bosch.com> This patchset adds rcar- display unit color management module (CMM) function feature, Which allows correction and adjustment of the display data, through updating Look up table (gamma) and Cubic look up table (CTM) property values Base color management module reference code taken from below link, https://github.com/renesas-rcar/du_cmm . - In above code, modified variable namingâ€™s and removed un used functionalities. - Introduce new functions for queueing cubic look up table and look up table events. - Implemented interfaces in color management module to set CLU /LUT table using standard DRM data structures as input. Look up table is a 1D-LUT that converts each of three-color components by using a lookup table. LUT is used for gamma correction. Cubic look up table is a three-dimensional LUT (3D-LUT) that converts the input three-color-component data into desired three color Components by using a lookup table - Implemented atomic check helper functions for enable/disable LUT and CLU (Gamma and Color Transformation Matrix properties). - Allocated memory necessary for cubic look up table and look up table and added mode fix up callback function - Added update gamma and color transformation matrix properties in commit tail function, If any change in property values. kalakodima venkata rajesh (8): drm: Add DU CMM support functions drm: Add DU CMM support boot and clk changes drm: rcar-du: Give a name to clu table samples drm: rcar-du: Refactor the code with new functions drm: rcar-du: Implement interfaces to set clu and lut using drm data structures drm: rcar-du: Implement atomic_check to check for gamma and ctm properties drm: rcar-du: update gamma and ctm properties in commit tail drm: rcar-du: Add shutdown callback function in platform_driver .../boot/dts/renesas/r8a7795-es1-salvator-x.dts | 5 + arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts | 5 + .../arm64/boot/dts/renesas/r8a7795-salvator-xs.dts | 5 + arch/arm64/boot/dts/renesas/r8a7795.dtsi | 29 +- arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dts | 6 +- .../arm64/boot/dts/renesas/r8a7796-salvator-xs.dts | 4 + arch/arm64/boot/dts/renesas/r8a7796.dtsi | 25 +- .../arm64/boot/dts/renesas/r8a77965-salvator-x.dts | 7 +- .../boot/dts/renesas/r8a77965-salvator-xs.dts | 7 +- arch/arm64/boot/dts/renesas/r8a77965.dtsi | 27 +- drivers/clk/renesas/r8a7795-cpg-mssr.c | 4 + drivers/clk/renesas/r8a7796-cpg-mssr.c | 3 + drivers/clk/renesas/r8a77965-cpg-mssr.c | 106 +- drivers/gpu/drm/bridge/synopsys/dw-hdmi.c | 35 + drivers/gpu/drm/rcar-du/Makefile | 2 + drivers/gpu/drm/rcar-du/rcar_du_cmm.c | 1470 ++++++++++++++++++++ drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 82 ++ drivers/gpu/drm/rcar-du/rcar_du_crtc.h | 28 + drivers/gpu/drm/rcar-du/rcar_du_drv.c | 85 +- drivers/gpu/drm/rcar-du/rcar_du_drv.h | 16 +- drivers/gpu/drm/rcar-du/rcar_du_encoder.c | 2 +- drivers/gpu/drm/rcar-du/rcar_du_encoder.h | 1 + drivers/gpu/drm/rcar-du/rcar_du_group.c | 5 + drivers/gpu/drm/rcar-du/rcar_du_kms.c | 25 + drivers/gpu/drm/rcar-du/rcar_du_regs.h | 92 ++ include/drm/bridge/dw_hdmi.h | 1 + include/drm/drm_atomic.h | 25 + include/drm/drm_ioctl.h | 7 + 28 files changed, 2082 insertions(+), 27 deletions(-) create mode 100644 drivers/gpu/drm/rcar-du/rcar_du_cmm.c -- 2.7.4

[PATCH 1/4] drm/i915/dsi: Fix pipe_bpp for handling for 6 bpc pixel-formats
by Hans de Goede 05 Apr '19

05 Apr '19

There are 3 problems with the dsi code's pipe_bpp handling for 6 bpc pixel-formats which this commit addresses: 1) It assumes that the pipe_bpp is the same as the bpp going over the dsi lanes. This assumption is not valid for MIPI_DSI_FMT_RGB666, where pipe_bpp should be 18 so that we do proper dithering but we actually send 24 bpp over the dsi lanes (MIPI_DSI_FMT_RGB666_PACKED sends 18 bpp). This assumption is enforced by an assert in *_dsi_get_pclk(). This assert triggers on the initial hw-state readback on BYT/CHT devices which use MIPI_DSI_FMT_RGB666, such as the Prowise PT301 tablet. PIPECONF is set to 6BPC / 18 bpp by the GOP, while mipi_dsi_pixel_format_to_bpp() returns 24. This commits switches the calculations in *_dsi_get_pclk() to use the bpp from mipi_dsi_pixel_format_to_bpp(intel_dsi->pixel_format) which returns the bpp going over the mipi lanes and drops the assert. 2) On BXT bxt_dsi_get_pipe_config() wrongly overrides the pipe_bpp which i9xx_get_pipe_config() reads from PIPECONF with the return value from mipi_dsi_pixel_format_to_bpp(). This avoids the assert from 1. but is wrong since the pipe is actually running at the value configured in PIPECONF. This commit drops the override of pipe_bpp from bxt_dsi_get_pipe_config(). 3) The dsi encoder's compute_config() never assigns a value to pipe_bpp, unlike most other encoders. Falling back on compute_baseline_pipe_bpp() which always picks 24. 24 is only correct for MIPI_DSI_FMT_RGB88 for the others we should use 18 bpp so that we correctly do 6bpc color dithering. This commit adds code to intel_dsi_compute_config() to properly set pipe_bpp based on intel_dsi->pixel_format.
