Just for documentation purposes, to get linux-next-20220930 booting on
the QDrive3 with the upstream arm64 defconfig I had to apply the
following patches:
- arm64: dts: qcom: sc8280xp: fix UFS PHY serdes size
https://lore.kernel.org/linux-arm-msm/20220915141601.18435-1-johan+linaro@kernel.org/
Without this, the phy fails to probe due to the following error:
qcom-qmp-ufs-phy 1d87000.phy: can't request region for resource [mem 0x01d87400-0x01d87507]
qcom-qmp-ufs-phy 1d87000.phy: failed to create lane0 phy, -16
qcom-qmp-ufs-phy: probe of 1d87000.phy failed with error -16
- This hack patch is still needed:
disable has_address_auth_metacap and has_generic_auth
https://github.com/andersson/kernel/commit/d46a4d05d5a17ff4447af08471edd78e194d48e5
Without this, the boot hangs at:
rcu: srcu_init: Setting srcu_struct sizes based on contention.
arch_timer: cp15 and mmio timer(s) running at 19.20MHz (virt/virt).
clocksource: arch_sys_counter: mask: 0xffffffffffffff max_cycles: 0x46d987e47, max_idle_ns: 440795202767 ns
sched_clock: 56 bits at 19MHz, resolution 52ns, wraps every 4398046511078ns
- My UFS clock patch is still needed:
arm64: dts: qcom: sc8280xp: correct ref_aux clock for ufs_mem_phy
https://lore.kernel.org/lkml/20220830180120.2082734-1-bmasney@redhat.com/T/#u
- I didn't use an initrd for testing so I had to change the options
CONFIG_SCSI_UFS_QCOM and CONFIG_PHY_QCOM_QMP from =m to =y.
