BugLink: https://bugs.launchpad.net/bugs/1947829 [Impact] Sometimes MT7921 may not be probed due to an endless mcu reset: [ 5.789548] mt7921 mcu reset 0 [ 5.790625] mt7921 rx type 0x7 [ 5.790625] mt7921 eid 0x1 ext_eid 0x0 [ 5.790626] mt76_rx_event eid 0x1 ext_eid 0x0 [Fix] WiFi and Bluetooth firmware updates from mainline: * e5a80ef8 linux-firmware: update frimware for mediatek bluetooth chip (MT7921) * d34196f5 linux-firmware: update firmware for MT7921 WiFi device [Test Case] This should fix the mcu reset and wireless/bluetooh devices should be probed successfully. [Where problems could occur] While there is explicit FW API for kernel version compatibility checking, this might introduce some hidden glitches that we don't know yet. [Other Info] MT7921 is supported since Impish 5.13 kernel, and Impish already has the latest Bluetooth firmware, so only the WiFi one is proposed. For oem-5.13 and oem-5.14 in Focal, both firmware updates for Bluetooth and WiFi are required. ---------------------------------------------------------------- The following changes since commit dbd025299a27674401c31c9f055abc3044807627: UBUNTU: [Packaging] rebase-upstream: Add a bug reference if env variable LP is set (2021-09-30 08:12:32 +0200) are available in the Git repository at: https://git.launchpad.net/~vicamo/ubuntu/+source/linux-firmware bug-1947829/mt7921-mcu-reset/impish-pull for you to fetch changes up to 721e33dc2e615e810a3b4e0de0cb13e6083560f7: linux-firmware: update firmware for MT7921 WiFi device (2021-10-20 14:47:05 +0800) ---------------------------------------------------------------- Deren Wu (1): linux-firmware: update firmware for MT7921 WiFi device WHENCE | 4 ++-- mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin | Bin 92192 -> 92192 bytes mediatek/WIFI_RAM_CODE_MT7961_1.bin | Bin 685320 -> 689864 bytes 3 files changed, 2 insertions(+), 2 deletions(-) diff --git a/mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin b/mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin index 15c68961..d63e48da 100644 Binary files a/mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin and b/mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin differ diff --git a/mediatek/WIFI_RAM_CODE_MT7961_1.bin b/mediatek/WIFI_RAM_CODE_MT7961_1.bin index 9de3d1d4..2a0599f5 100644 Binary files a/mediatek/WIFI_RAM_CODE_MT7961_1.bin and b/mediatek/WIFI_RAM_CODE_MT7961_1.bin differ
