Hi Hector I’ve applied the following patchset (arranged in chronological order) to linux 6.2, and wifi seems to have broken on MacBookPro16,1 (brcmfmac4364b3) https://lore.kernel.org/asahi/20230212063813.27622-1-marcan@xxxxxxxxx/T/#t (BCM4355/4364/4377 support & identification fixes) https://lore.kernel.org/asahi/20230214080034.3828-1-marcan@xxxxxxxxx/T/#t (Apple T2 platform support) https://lore.kernel.org/asahi/20230214091651.10178-1-marcan@xxxxxxxxx/T/#t (BCM4387 / Apple M1 platform support) https://lore.kernel.org/asahi/b4489e24-e226-4f99-1322-cab6c1269f09@xxxxxxxxxxxx/T/#t (brcmfmac: cfg80211: Use WSEC to set SAE password) The logs show: Feb 23 20:08:57 MacBook kernel: usbcore: registered new interface driver brcmfmac Feb 23 20:08:57 MacBook kernel: brcmfmac 0000:05:00.0: enabling device (0000 -> 0002) Feb 23 20:08:57 MacBook kernel: brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4364b3-pcie for chip BCM4364/4 Feb 23 20:08:57 MacBook kernel: brcmfmac 0000:05:00.0: Direct firmware load for brcm/brcmfmac4364b3-pcie.Apple Inc.-MacBookPro16,1.bin failed with error -2 Feb 23 20:08:57 MacBook kernel: brcmfmac 0000:05:00.0: Direct firmware load for brcm/brcmfmac4364b3-pcie.bin failed with error -2 Feb 23 20:08:57 MacBook kernel: brcmfmac 0000:05:00.0: brcmf_pcie_setup: Dongle setup failed I also tested the patchiest in the following link, and wifi mostly worked there (occasionally it complained about some pic error, I’ll save the logs next time I encounter that) : https://github.com/t2linux/linux-t2-patches/blob/main/8001-asahilinux-wifi-patchset.patch Thanks Aditya > On 14-Feb-2023, at 1:30 PM, Hector Martin <marcan@xxxxxxxxx> wrote: > > Hi all, > > This short series adds the missing bits to support Apple T2 platforms. > > There are two quirks: these devices have firmware that requires the > host to provide a blob of randomness as a seed (presumably because the > chipsets lack a proper RNG), and the module/antenna information that > is used for Apple firmware selection and comes from the Device Tree > on ARM64 systems (already upstream) needs to come from ACPI on these > instead. > > Changes since the megaseries from a ~year ago: made the ACPI code bail > if there is no module-instance, so we don't try to get the antenna > info at all in that case (as suggested by Arend).
