From time to time, my apq8096-db820c fails to boot to userspace, reset back to
fastboot and locks up: to easily reproduce the issue, i'm boot looping using a
cron job with a 1 min reboot entry on the board while leaving a "while 1; do
fastboot boot boot.img; done" on the host pc.

The issue is present in mainline up to 5.2-rc4, using defconfig and:

CONFIG_SCSI_UFS_QCOM=y
CONFIG_PHY_QCOM_QMP=y
CONFIG_PHY_QCOM_UFS=y

but was present in previous releases too (e.g. 4.14., 4.19, etc qcom-lt or
mainline), where it's even easier to reproduce (e.g. takes way less reboots to
trigger it).

These are the last lines printed out:

Any idea what is going on? Am i doing something wrong?

Hello Paolo,

I have a guess of what is going on.
db820c has 3 PCIe controllers,
that shares a singe QMP block (that has clocks, regulators, and resets).
The QMP block has 3 PCIe PHYs, that have their own clocks and resets.

^^ here the phy_init() called from pcie-qcom.c
which ends up to a call to qcom_qmp_phy_enable()

which has this code:

        ret = qcom_qmp_phy_com_init(qphy);
        if (ret)
                return ret;

qcom_qmp_phy_com_init() has this code:

        if (qmp->init_count++) {
                mutex_unlock(&qmp->phy_mutex);
                return 0;
        }

qcom_qmp_phy_com_init() later fails,
since the common block init time out, so the qmp driver
disables clocks, asserts reset, and disables regulators

> [    7.550891] qcom-pcie: probe of 600000.pcie failed with error -110

^^ here the second PCIe controller is probed.

it will call phy_init()

which will again call qcom_qmp_phy_enable() which will call
qcom_qmp_phy_com_init()

where this code:

        if (qmp->init_count++) {
                mutex_unlock(&qmp->phy_mutex);
                return 0;
        }

now will return 0,

so clocks will never be enabled, resets never deasserted, regulators
never enabled.

since qcom_qmp_phy_com_init() returns success in this case,
qcom_qmp_phy_enable() will try to continue with the init,
and writes to disabled hardware is usually not a good idea.

I think the proper fix for this is:

diff --git a/drivers/phy/qualcomm/phy-qcom-qmp.c b/drivers/phy/qualcomm/phy-qcom-qmp.c
index cd91b4179b10..22352e3b0ec5 100644

+               goto err_lane_rst;
 
        if (cfg->has_lane_rst) {
                ret = reset_control_deassert(qphy->lane_rst);



Kind regards,
Niklas

Hi Niklas,
unfortunately, it didn't help - i added a printk, to highlight when it failed:

--- a/drivers/phy/qualcomm/phy-qcom-qmp.c

-               return ret;
+       if (ret) {

+               goto err_lane_rst;

        if (cfg->has_lane_rst) {
                ret = reset_control_deassert(qphy->lane_rst);

After several reboots i was able to trigger the phy init failure again:

...

[    2.224956] qcom-qmp-phy 7410000.phy: Registered Qcom-QMP phy

...

these are the last lines printed, before rebooting in fastboot and
locking up there (as before[*]).

So, as far as i understand there are two distinct problems:

1) sometimes, qcom-qmp-phy fails to initialize

2) and when that happens, the failure is fatal and it led to a reboot & lockup
in fastboot

I still think that the above patch is correct,
even though it didn't fix your problem.

If you try to disable the two other PCIe controllers:

diff --git a/arch/arm64/boot/dts/qcom/apq8096-db820c.dtsi b/arch/arm64/boot/dts/qcom/apq8096-db820c.dtsi

Can you still reproduce the reboot?

                };

disabling the two other pci controllers (and leaving your previous patch
applied), made the issue more frequent: i was never able to boot to user space
three times in a row without experiencing a crash, previously it was more
sporadic.

On the other hand, now i can reproduce the issue more easily this way.
