User $ grep -rB1 'MODULE_FIRMWARE.*SKL' /usr/src/linux/drivers/gpu/drm/i915 /usr/src/linux/drivers/gpu/drm/i915/intel_guc_fw.c-#define I915_SKL_GUC_UCODE GUC_FW_PATH(skl, SKL_FW_MAJOR, SKL_FW_MINOR) To identify the firmware file name, either by checking /var/log/kern.log: tgl_guc_70.bin and HuC firmware does not have a version number e.g. GuC firmware for Gen 12+ now only uses major version numbers e.g. 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. An example is available as a part of the dracut article.Īlternatively compile the i915 driver as a kernel module and it will automatically load the firmware from the filesystem. 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: ↑ Requires at least kernel version 6.0.0 and Mesa 22.2Ī full list of Intel CPU graphic capabilities is here.↑ Broxton is the name of the graphics core associated with the Goldmont microarchitecture (Apollo Lake platform, among others).↑ Cherryview is the name of the graphics core associated with the Airmont microarchitecture (Braswell, Cherry Trail platforms, among others).↑ 4.0 4.1 Used to be supported by proprietary Legacy OpenCL drivers from Intel, which are no longer maintained.↑ Valley View is the name of the graphics core associated with the Silvermont microarchitecture (Bay Trail platform, among others).↑ 2.0 2.1 2.2 2.3 Used to be supported by Beignet project which is now deprecated and no longer maintained. ↑ 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.
