@ Rex, If we apply the [1], it will make users easily reproduce the [2], that is why kernel maintainer reverted the [1].
I thought I backport the [2] to the kernel first, then backport [1] to the kernel, I tried to backport the [2] to the osp1 kernel myself, but it didn't work at all, so I asked for help to Intel, they estimated a couple of days then tell me it is not easy and they will not help backport the [2] to 5.0 and 5.3, and without [1], the dmic function will not be affected. About the linux-firmware, already sru them to Eoan and Bionic with this bug: https://bugs.launchpad.net/ubuntu/+source/linux- firmware/+bug/1859387, the firmware under Eoan and Bionic can support the kernel both with [1] and without [1]. Because this bug will not affect the dmic function, just lower the priority, when I finish the more urgent bug, I will spend more time investigating backport [2], then resend the patch [1]. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1857409 Title: alsa/sof: load different firmware on different platforms Status in HWE Next: New Status in OEM Priority Project: New Status in linux package in Ubuntu: Confirmed Status in linux-oem-osp1 package in Ubuntu: Fix Released Status in linux-oem-osp1 source package in Bionic: Confirmed Status in linux source package in Eoan: Confirmed Status in linux source package in Focal: Confirmed Bug description: [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 [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 [Test Case] Prepare the firmware from https://github.com/thesofproject/linux-firmware master branch, then boot the kernel with these patches. [Regression Risk] Low, just let different platforms load differnt firmware, and these patches are in the upstream kernel.
