Otherwise, it is possible to always have a black screen unless nomodeset is passed to the kernel, thus disabling kernel mode setting (KMS).
Section "Device" Identifier "Device0" Driver "intel" Option "AccelMethod" "SNA" Option "TearFree" "true" EndSection Or by grepping the MODULE_FIRMWARE in the kernel source tree: Kernel: HuC: Failed to fetch firmware i915/kbl_huc_ver01_07_1398.bin (error -2) Kernel: GuC: Failed to fetch firmware i915/kbl_guc_ver9_33.bin (error -2) To identify the firmware file name, either by checking /var/log/kern.log: Disable it if the system experiences freezing (for example, after resuming from hibernation). Enabling GuC/HuC firmware loading causes issues in some systems. HuC firmware (and GuC as a dependent) is needed for AVC/HEVC/VP9 low power encoding bitrate control, including CBR, VBR, etc. It is possible to enable loading of the firmware using kernel parameter i915.enable_guc_loading=1 (before kernel 4.16) or i915.enable_guc=3 (since kernel 4.16).
įor Gen11+ GPUs, GuC/HuC firmware loads by default since Linux 5.4 (see commit).įor Gen9 and Gen9.5 GPUs, GuC/HuC firmware won't load by default. HEVC/H.265 ♜ontroller firmware improves hardware acceleration of media decoding. Graphics ♜ontroller firmware offloads functions from the host driver. Including the firmware in-kernel may cause suspend-to-ram to fail, if this is a concern don't include the blob built into the kernel, instead, add the firmware blob into the initramfs. Systems using Skylake, Broxton, or newer Intel graphics will need additional firmware from sys-kernel/linux-firmware package:
Information on HD Graphics 4000 and UHD Graphics 605 compatibility with other computer components. Pipelines / CUDA coresĬompatibility, dimensions and requirements Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.
These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed.
