Hello,
I'm looking for help with the following issue.
I'm trying to upgrade kernel on my custom iMX6sx board from very old
4.9.146 to resent 6.17. The board has eMMC connected to usdhc4, and
u-boot happily starts kernel from eMMC. The kernel boot sequence,
however, hangs waiting for root file-system as it doesn't see eMMC.
I figured that if I disable DTS "gpc/pgc/pd_pu" node in imx6sx.dtsi one
way or another, the board starts to boot, so it seems that with default
configuration the kernel power or clock management renders either usdhc4
or eMMC inactive.
Two methods to effectively disable "gpc/pgc/pd_pu" I've used to
work-around the problem are:
modified arch/arm/boot/dts/nxp/imx/imx6sx.dtsi
@@ -800,7 +800,7 @@ gpc: gpc@20dc000 {

+ .num_domains = 1,
.err009619_present = false,
.err006287_present = false,
};
and any of the two gives kernel that boots.
I looked at DTS files in the kernel that use imx6sx.dtsi as well, but
didn't find anything specific that'd help me with the problem.
I'm not sure how to debug this further and actually fix the issue. Any
ideas, please?
Below is success boot log. Failing boot hangs at or sometimes slightly
above the "Waiting for root device /dev/mmcblk0p2..." line, and has
additional
"imx-gpc 20dc000.gpc: probe with driver imx-gpc failed with error -2"
diagnostic due to my hack to disable "gpc" DTS node by commenting-out
"ipg" clock.
The only suspect thing I see in the log is:

and I'm not sure if it's relevant or expected.

I tried booting 6.17 on an imx6sx-sdb board and it booted successfully:

Thank you so much for checking! I think I'll try to compare my build to
this one, as I still have no other idea how to debug my problem. Could
you please send me resulting DTB file as well so that I can check my
build system against yours?

You have these cycles as well. Is it expected? I fail to see why gpc and
clock-controller end-up being mutually dependent. Besides, they are not
mutually dependent in the hardware, or are they?
I also have a few more doubts about imx6sx.dtsi:
1. Documentation/usage-model.rst suggests "interrupt-parent = <&intc>;"
to be root node property, not of /soc as in imx6sx.dtsi. Is this
essential?
2. intc: in imx6sx.dtsi is interrupt-parent of itself? If it needs to
be, this asks for an explanation in a comment?
intc: interrupt-controller@a01000 {
compatible = "arm,cortex-a9-gic";
#interrupt-cells = <3>;
interrupt-controller;
reg = <0x00a01000 0x1000>,
<0x00a00100 0x100>;
interrupt-parent = <&intc>;
};
3. Some nodes have <&intc>, and some <&gpc> as interrupt-parent. Could
somebody please re-check if it makes sense? Besides, "gpc" is not true
interrupt controller, right?
Thanks,

I have sent you the dtb off list.
I haven't had a chance to look at your questions yet.

I've checked that I end-up with the same DTB as you sent me off-list for
this configuration, so at least this part seems to work fine on my side.
I also tried the imx_v6_v7_defconfig - based kernel on my board
(obviously with my custom DTB), and the kernel still doesn't boot.
Further, I've found that it's enough to disable CONFIG_REGULATOR_ANATOP
in my custom kernel config to get kernel to see eMMC card, and then
mount it as root file-system.
I still fail to see what I do (or don't do) in my DTS (or kernel config)
to confuse the kernel, and how to figure that out. Any ideas?

Please share your dts so we can take a look.

It is built form multiple .dtsi, so I figure I attach the one after
pre-processing stage. Please let me know if you'd prefer I rather
manually insert all the custom .dtsi into a single .dts, and send that
one instead.

This format is hard to follow.
To make things easier for debugging, you could create a minimal board
dts file with only UART and eMMC nodes to reproduce the problem.
It's not clear to me the relationship between the ANATOP regulators
and the eMMC power on your board.

FYI, we have had some strange issues cropping up in regards to the
so-called ->sync_state() support in genpd, that was added in
v6.17-rc1. Not sure if this could be related.
Most of the problems pointed to commit: 0e789b491ba0 "pmdomain: core:
Leave powered-on genpds on until sync_state".
Although, it's not possible to make a plain revert of the above
commit, one can opt-out from the new behavior in genpd, by setting
GENPD_FLAG_NO_STAY_ON for the corresponding genpds that are registered
with pm_genpd_init().
Kind regards
Uffe

Please see attached minimum DTS. Maybe it misses something? Shouldn't
DTS describe how eMMC chip is powered, provided it's powered from NXP
MMPF0100F6ANES PMIC? I didn't find any hints in other DTS'es.

Sheer mystery for me.
The point of hang is not entirely deterministic either, that suggests
it's some power problem indeed. It may hang after random line among the
following depending on exact build and sometimes even from run-to-run:
...

check access for rdinit=/init failed: -2, ignoring
Waiting for root device /dev/mmcblk0p2...
Also, I just tried to compile entire kernel with -DDEBUG, and it starts
to see the eMMC, though still hangs not ever mounting the root FS:

Yes, the dts should describe the eMMC power supplies.
The properties are: vmmc-supply and vqmmc-supply.
Check arch/arm/boot/dts/nxp/imx/imx6qdl-colibri.dtsi for reference.

Does it hang if you pass "pm_genpd_ignore_unused" and
"clk_ignore_unused" in the kernel command line?

I saw Ulf's response about a potential regression in 6.17.
Do you see the hang with 6.16?

Another suggestion: if your eMMC operates only at 3.3V, try passing
the "no-1-8-v" property for usdhc4.

It does use 1.8. The rest of your suggestions I'll check and then get
back, thank you!

This uses:
pmic: pmic@8 {
compatible = "fsl,pfuze100";
that doesn't look like the one I need, and I don't see anything among
Documentation/devicetree/bindings/regulator/* for the NXP MMPF0100F6ANES
PMIC that is used on my board.
Does it mean that this regulator is unsupported? If so, doesn't it mean
that kernel simply won't touch it, and thus it can't be the cause of the
hang?
Anyway, I added naive fixed regulators (see attached modified DTS), but
it didn't change the outcome.

Yep, it still hangs (it's pd_ignore_unused, not pm_genpd_ignore_unused,
btw):
clk: Not disabling unused clocks
PM: genpd: Not disabling unused power domains
check access for rdinit=/init failed: -2, ignoring
Waiting for root device /dev/mmcblk0p3...
and I recall I've already tried it first thing to disable this right in
the code to no avail either.

Yep, 6.16 still hangs for me the same way.

Now after further investigations of the issue I find that success
a bit surprising.
I've found that my problem is cured by a commit in
https://github.com/nxp-imx/linux-imx
that works-around an issue that looks like imx6sx generic problem, and
should probably cause troubles on imx6sx-sdb board as well, but doesn't?
The commit is:
commit 65cf3a49ab15cdbbede3c97fd6bba731a3cd366f

MLK-11375-2 ARM: imx: disable cpuidle for imx6sx
i.MX6SX CPUIdle with ARM core power down has issue
and cause system hang during kernel boot up, disable
it for now and will enable it when busfreq driver
is ready.
Later (by the DAG, not by date) on the same imx_4.9.11_1.0.0_ga
branch at that repo, there is:
commit 816978f83b1d8dd6ce3bd5dd62223dbfdf74bdd3
Author: Anson Huang <b20788@freescale.com>

Commit: Octavian Purdila <octavian.purdila@nxp.com>
CommitDate: Thu Feb 23 14:21:42 2017 +0200
MLK-9708 arm: imx: add low power idle support for i.mx6sx
that effectively reverts the aforementioned commit while adding a lot of
other stuff. The resulting kernel also boots fine on my hardware.
Curiously enough, neither of these commits are there in the latest
branch lf-6.12.y there (and that kernel hangs on my board as well.)
Provided the latter commit is indeed the right fix for imx6sx support in
the kernel, what's the procedure to get it to the mainstream Linux
kernel?
Thanks,

It seems that your observation matches what Angelo (added on Cc)
reported a long time ago:
https://community.nxp.com/t5/i-MX-Processors/imx6sx-kernel-hangs-at-rootfs-mount/td-p/964920
I'd like to know if the bootloader version plays a role in the
different behavior that we see on the imx6sx-sdb versus your board.
I used U-Boot 2024.07 on my imx6sx-sdb. Which version did you use? Is
it based on an old NXP U-Boot tree?
Does using a recent bootloader make the hang disappear?

Uhh... U-Boot is very old and is heavily modified anyway. I figure our
local history starts at:
rel_imx_4.1.33_7ulp_beta
commit 43bff39513ae89c476751caff427b9855af78f7e
Author: Ye Li <ye.li@nxp.com>
Date: Fri Apr 14 13:44:48 2017 +0800
MLK-14693 mx7ulp: Change PLL rate calculation to avoid div 0
that looks like NXP tree to me indeed, likely taken once upon a time
from:
https://gitlab.com/jcgit/uboot-imx.git
that was a mirror of original NXP repository
git://git.freescale.com/imx/uboot-imx.git
That said, I wanted to get to recent kernel using working u-boot, then
maybe try to upgrade u-boot as well, but maybe even not. No reason as of
yet, especially as it's difficult for me to recover from a brick state
should boot-loader fail.

I attempted to build a U-Boot from this branch for the imx6sx-sdb
board, but it failed to compile with recent compilers.
If you send me a U-Boot binary for imx6sx-sdb from this branch
off-list, I can give it a try here.

I fail to figure how to build it for imx6sx-sdb:
$ git branch -a --contains rel_imx_4.1.33_7ulp_beta
remotes/vendor/imx_v2016.03_4.1.33_7ulp_beta
$ git co imx_v2016.03_4.1.33_7ulp_beta
branch 'imx_v2016.03_4.1.33_7ulp_beta' set up to track 'vendor/imx_v2016.03_4.1.33_7ulp_beta'.
Switched to a new branch 'imx_v2016.03_4.1.33_7ulp_beta'
$ cd configs
$ ls *imx*
imx31_phycore_defconfig picosom-imx6ul-qspi_defconfig
imx31_phycore_eet_defconfig picosom-imx6ul_defconfig
$
What defconfig did you use?

It still boots for me. Please see the log below. I tested several boots.
My board is a very old one, with i.MX6SX version 1.0.
Looking at the commit you mentioned:
https://github.com/nxp-imx/linux-imx/commit/816978f83b1d8dd6ce3bd5dd62223dbfdf74bdd3
It does add an 'if (imx_get_soc_revision() >= IMX_CHIP_REVISION_1_2) '
check, so maybe this cpuidle fix is silicon version dependent?
Such a commit is huge. Could you add only the code under the above
'if' logic to see if it works in mainline?

I'm not familiar with the code and can't figure what exactly I'm
expected to check. Could you please prepare a patch, and I'll be happy
to apply and check it.

Here is a patch you can try.
It's not a formal patch yet, as it needs to be split.

Subject: [PATCH] ARM: imx6sx: Initialize RC-OSC for TO1.2+ to fix low-power
idle hang
i.MX6SX silicon revision TO1.2 and later power off the 24 MHz XTAL
during low-power idle and switch to the internal RC oscillator.
Without proper RC-OSC initialization, this transition can hang early
in boot or resume from idle.
Boards based on TO1.0/TO1.1 do not exhibit this behavior since the
XTAL remains powered, so the initialization is only needed for TO1.2+.
This change conditionally enables and tunes the RC-OSC before cpuidle
setup for TO1.2 and newer silicon revisions.
Based on the following commit from the NXP vendor kernel:

As I've already reported, this patch unfortunately doesn't solve my
issue, but then things got even more "interesting".
Before I've said that latest kernel branch lf-6.12.y on
https://github.com/nxp-imx/linux-imx does not have the 816978f83b
commit, but yesterday I've found it does include similar change though
with different commit message and without any reference to the original
commit (that's why I missed it):
https://github.com/nxp-imx/linux-imx/commit/3f127cc4f5f0f1c8563390c4db7727fcb5735aa9
Now, this commit does *not* solve my problem either. I.e., lf-6.12.y
still hangs on my board. I even tried to cherry-pick the original
816978f83b on top of this, and all the conflicts I got look formal
rather than functional, leaving code unchanged after resolution, so this
commit is in fact almost perfect cherry-pick of the original 816978f83b
that did solve my problem on the imx_4.9.11_1.0.0_ga branch of that
repository.
Yet another thing I figured that it's unlikely powering problem, as both
3.3 and 1.8 are still there on eMMC when the board hangs. Clocks are
most probable suspect then.
I'm going to dig into imx_4.9.11_1.0.0_ga branch again more carefully to
try to figure what's going on, and what actually either fixes or
work-arounds the problem at hand.

Well, that activity ended up being almost useless. Even though I've
found yet another patch that "fixes" the build for my board in
imx_4.9.11_1.0.0_ga branch, it happens to cure neither latest mainstream
kernel nor NXP lf-6.12.y branch.
For reference, the patch is:
https://github.com/nxp-imx/linux-imx/commit/fe3aca041b0b8042d59bcf1d9169109c9220e783
I figure the only sensible option that is left is to try to actually
debug the issue on my board using either the latest mainstream kernel,
or lf-6.12.y by NXP (which one is more promising BTW?), but right
now I have no idea where to start. Any hints?
Also, could you please comment on the issues I've raised earlier, to help
me better understand the state of iMX6SX support:
1. Documentation/usage-model.rst suggests "interrupt-parent = <&intc>;"
to be root node property, not of /soc as in imx6sx.dtsi. Is this
essential? Anyway, shouldn't either documentation or implementation be
fixed to agree on this?
2. intc: in imx6sx.dtsi is interrupt-parent of itself? Is it a mistake?
If not, this asks for an explanation in a comment?
intc: interrupt-controller@a01000 {
compatible = "arm,cortex-a9-gic";
#interrupt-cells = <3>;
interrupt-controller;
reg = <0x00a01000 0x1000>,
<0x00a00100 0x100>;
interrupt-parent = <&intc>;
};
3. Some nodes have <&intc>, and some <&gpc> as interrupt-parent. Could
somebody please re-check if it makes sense? Besides, "gpc" is not true
interrupt controller, right, so what's the matter of having it as
interrupt-parent for some nodes?
4. Suspect cycles in DTS:
/soc/bus@2000000/clock-controller@20c4000: Fixed dependency cycle(s) with /soc/bus@2000000/gpc@20dc000
/soc/bus@2000000/gpc@20dc000: Fixed dependency cycle(s) with /soc/bus@2000000/clock-controller@20c4000
/soc/bus@2000000/clock-controller@20c4000: Fixed dependency cycle(s) with /soc/bus@2000000/gpc@20dc000
/soc/bus@2000000/gpc@20dc000: Fixed dependency cycle(s) with /soc/bus@2000000/clock-controller@20c4000
/soc/bus@2000000/gpc@20dc000: Fixed dependency cycle(s) with /soc/bus@2000000/clock-controller@20c4000
Are they to better be manually fixed?
