** Description changed: [Impact] - In our ubuntu kernel, the sof driver will load the sof-cnl.ri (firmware) - on all platforms, but mainline kernel already supported the multi - firmwares on differnt platforms, and OEM project needs us to - support the mutli-firmware names in the ubuntu kernel + Intel released a new version sof firmware to Canonical, they suggested + that we should integrate the version v1.3-0f73628 and we should only + pick the cml and cnl firmwares since other firmwares are not fully + tested. Since we have a couple of Lenovo and Dell cnl and cml machines + which need to enable sof driver, we integrate the firmwares to + ubuntu. [Fix] - cherry-pick 3 upstream patches, then on cnl platforms, it will - load sof-cnl.ri, on cml platfomrs, it will load sof-cml.ri, on cfl - platforms, it will load sof-cfl.ri + - fix the hang issue in the firmware for the cml and cnl + - introduce the ldc file which helps to do the firmware debug + - divide the firmware to cml and cnl specific ones + [Test Case] - Prepare the firmware from https://github.com/thesofproject/linux-firmware - master branch, then boot the kernel with these patches. + These firmwares are already widely used in oem project, the audio + functions worked very well under both Lenovo and Dell dmic machines. [Regression Risk] - Low, just let different platforms load differnt firmware, and these - patches are in the upstream kernel. + Low, Intel released these firmware to us, and we already did large + numbers audio test in the oem project.
