Rule #4: Give competitors' recommendations only where appropriate. No religion/politics unless it is directly related to Intel Corporation

Rule 3: All posts must be related to Intel or Intel products. Rule 2: No Unoriginal Sources, Referral links or Paywalled Articles. If you can't say something respectfully, don't say it at all. This includes comments such as "retard", "shill", "moron" and so on. Uncivil language, slurs, and insults will result in a ban. Luckily, this is easy enough to modify, as long as the kernel version is >= 3.13.x and < 4.2.Subreddit and discord for Intel related news and discussions. If it is, or when the brightness buttons are working, the issue is that the kernel can not detect where the brightness control is. īrightness does not change with keyboard shortcutsįirst, make sure vendor compatibility is on in the kernel configuration: Toshiba for Toshiba, etc.

Kernel with version 4.2 or newer is needed with some 8th generation chipsets.

This is usually done through the bootloader. acpi_osi="Linux" can be passed to the kernel command line to try to solve this issue. Otherwise, it is possible to always have a black screen unless nomodeset is passed to the kernel, thus disabling kernel mode setting (KMS).

According to this Debian wiki, CONFIG_FRAMEBUFFER_CONSOLE must be set to y (aka built-in to the kernel).

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:

↑ Broxton is the name of the graphics core associated with the Goldmont microarchitecture (Apollo Lake platform, among others)Ī full list of Intel CPU graphic capabilities is here.

↑ 5.0 5.1 5.2 5.3 5.4 Supported by dev-libs/intel-compute-runtime.

↑ Cherryview is the name of the graphics core associated with the Airmont microarchitecture (Braswell, Cherry Trail platforms, among others).

dev-libs/intel-neo was superseded by dev-libs/intel-compute-runtime. Both packages are no longer maintained, thus currently unavailable.

↑ 3.0 3.1 Used to be supported by dev-libs/intel-neo, which superseded dev-libs/beignet ( Upstream info) as of Q1/2020.

↑ Valley View is the name of the graphics core associated with the Silvermont microarchitecture (Bay Trail platform, among others).

↑ 1.0 1.1 Mesa 22.0 and higher have dropped support for i915 classic driver.

E.g., “3rd Gen” in the example lspci output above corresponds to “Gen7” in the table below. The lspci output for the graphics controller may refer to CPU generations, whereas the Feature support table below refers to GPU generations.
