Date: Mon, 22 Oct 2018 13:17:45 -0400 From: "F. Heitkamp" <heitkamp@...ritech.net> To: linux-kernel@...r.kernel.org Subject: Problem with XFX RX 580 on 4.18-19 I have a XFX Radeon 580 4GB installed on X58 chipset. I have only been able to get it to work on Linux 4.18.x and 4.19.x by using the amdgpu.dc=0 kernel boot parameter. It works up to the 4.17.19 kernel but the console font comes out shitty, pixelated and unreadable and it will not display well on my 4K monitor. e.g. console font is so bad it's unusable. In contrast I have another box which as a Radeon Vega 64 and the fonts/display are fantastic. I am using almost identical kernels and mesa/drm configuration. I also had the Vega 64 on the same box as the RX 580 previously and it worked fine; Fonts display were great. I have done some searching and I can't tell if it's a known problem for the polaris 20 GPU. Is anyone else experiencing a problem like this? This is the kernel config stanza that I use on both boxes. # Graphics support # # CONFIG_AGP is not set CONFIG_INTEL_GTT=m CONFIG_VGA_ARB=y CONFIG_VGA_ARB_MAX_GPUS=16 # CONFIG_VGA_SWITCHEROO is not set CONFIG_DRM=m CONFIG_DRM_MIPI_DSI=y # CONFIG_DRM_DP_AUX_CHARDEV is not set # CONFIG_DRM_DEBUG_SELFTEST is not set CONFIG_DRM_KMS_HELPER=m CONFIG_DRM_KMS_FB_HELPER=y CONFIG_DRM_FBDEV_EMULATION=y CONFIG_DRM_FBDEV_OVERALLOC=100 # CONFIG_DRM_LOAD_EDID_FIRMWARE is not set # CONFIG_DRM_DP_CEC is not set CONFIG_DRM_TTM=m CONFIG_DRM_VM=y CONFIG_DRM_SCHED=m # # I2C encoder or helper chips # CONFIG_DRM_I2C_CH7006=m CONFIG_DRM_I2C_SIL164=m # CONFIG_DRM_I2C_NXP_TDA998X is not set # CONFIG_DRM_I2C_NXP_TDA9950 is not set CONFIG_DRM_RADEON=m CONFIG_DRM_RADEON_USERPTR=y CONFIG_DRM_AMDGPU=m CONFIG_DRM_AMDGPU_SI=y CONFIG_DRM_AMDGPU_CIK=y CONFIG_DRM_AMDGPU_USERPTR=y # CONFIG_DRM_AMDGPU_GART_DEBUGFS is not set # # ACP (Audio CoProcessor) Configuration # CONFIG_DRM_AMD_ACP=y # # Display Engine Configuration # CONFIG_DRM_AMD_DC=y CONFIG_DRM_AMD_DC_DCN1_0=y # CONFIG_DEBUG_KERNEL_DC is not set # LSPCI Info: 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
