[Milan P. Stanić]

Hello,

Sorry to annoy again, but could you tell me if I sent this bug report
to right mail address or I should send it somewhere else.

Also, did I sent bug report correctly or I did some mistakes which
caused it to be ignored.

TIA

It sounds to me suspend-to-ram never works for this machine, at least
since 5.2.1. Am I right?

Sorry if I was not clear in previous mail. suspend-to-ram and resume works
fine if the machine doesn't mount internal emmc card to use it in way.

If it boots from external mmc card or ssd disk attached over usb-c
interface and use root filesystem (or any other filesystem, /home for
example) on them (external mmc or disk on usb-c) it can go numerous
times to suspend-resume cycles without any problem.

But if any filesystem from emmc mounted then in can suspend and even
resume, but when resumed after some random time it start to make
problems: programs segfault, cant read or write files and similar
issue.

As I wrote in previous mail I can apply patches, build kernel and
(maybe) tweak some parameters in kernel source (if I know which one
should help me) to help subsystem developers to fix this problem.

FWIW I've also tried suspend on my NanoPC-T4 and seen that the eMMC 
(also HS400-ES) fails to come back properly on resume (thus resume never 
completes due to the missing root filesystem). IIRC it might even have 
been reproducible with suspend-to-idle, but I'd have to double-check that.

I forgot to tell that emmc worked without problem on this machine with
ChromeOS kernel 4.4.xx downloaded from
https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4
and with patches from
https://github.com/archlinuxarm/PKGBUILDs/tree/master/core/linux-gru
for about two years (iirc).
Problem started when I switched to mainline kernels, somewhere around
5.1.xx

Re: PROBLEM: mmc_select_hs400es failed, error -110【请注意，邮件由linux-mmc-owner@vger.kernel.org代发】

[Milan P. Stanić]

Hi,

Anyone looked at this problem?

Or, is there better url or mailing list where I should send this bug
report?

Or, could someone tell me what I could try to fix it, which file and
parameters to change?

This is the mmc-list and since the rock-chips list was added by Shawn
- you have directed your question correctly.

The problem is, this isn't a list where everyone can get free support.
People may be working on other platforms, for example.

The best option for you, is probably to ping Shawn or to reach out to
some other Rock-chips people, as it seems like these guys needs to
have a closer look.

Well, if you can narrow down the problem that is always helpful. So
for example, is there any upstream kernel that works - or is it only
working through the chrome-os tree (which likely contains vendor
specific changes that are not upstream).

Kind regards

Problem is in that the in last 5-6 months chrome-os kernels even don't
boot, i.e. I only get blank display. I patched it for few releases
locally but for about 3-4 months even my patch doesn't work.
Maybe I could find chrome-os kernel about year or two old and try, but
even then I don't know where to look for this problem.

Other option is to try with mainline kernels from 4.20.x and up one by
one major release to look on which version this problem started. This
will take time because problem occurs irregularly, sometimes in a few
hours but sometimes it works fine for a few days until it appears.

Thank you for pointing me whom to ask and what to try.

Re: PROBLEM: mmc_select_hs400es failed, error -110【请注意，邮件由linux-mmc-owner@vger.kernel.org代发】

[Milan P. Stanić]

Hi all,

I built chromeOS kernel 4.4.174 and after three days with few
suspend-to-ram and resume mmc driver works fine, i.e. no problem
occured.

Could someone who know programming mmc drivers look at differences
between this chromeOS kernel (4.4.174) and some of mainline kernels
to find cause of the problem and maybe to create fix or patch to send
for testing.

That delta is more than 4 years of development. I am not sure
investigating the delta would make sense, however I leave that to
Rock-chips people to decide - or whomever that are willing to help to
debug this.

I think it is not needed to look at full delta from this working
chromeOS kernel and current mainline but maybe to 5.0 or 5.1 releases.

But I'm not sure and because I don't know what to look I can only hope
that rockchip developers will find what is wrong.

Anyway, I use this rk3399 gru-kevin chromebook with external mmc card
and it works fine if I don't 'touch' emmc. But is slower than when emmc
is used for root and home filesystem, significantly, and would be nice
if someone can find fix or just point me where and what to look.

More than a one year passed but this bug still persist on gru-kevin
chromebook. I'm testing this with every kernel release in hope it will
be fixed.
Now I'm tested it on  5.14.0-rc5

Does this happen if you limit the emmc from going into high speed
modes? (disable hs-200 and hs-400 modes)
I'm curious if it's an issue resuming the emmc at all, or if it's an
issue jumping back into high speed mode.
Depending on if the emmc gets power cycled and how they handle power
management, this can lead to a mode mismatch between the controller
and the emmc.
Also does it eventually sort itself out? For example if rootfs isn't
on the emmc and resume completes, does the emmc eventually become
unwedged?

I haven't started playing with power management on rk3399 yet, but at
least this will help isolate down where the issue is.

Let me describe what happens (sorry for bad English, I'm self taught).

This never happens with external mmc.

This happens only with internal emmc and only after resume from suspend
to ram if the internal emmc mounted or the machine is booted with emmc
only.

This happens on random time after resume, sometimes after 5-10 minutes,
sometimes hours and sometimes even after day or two.

Never happens if the machine isn't suspended to ram.

Could you tel me how can I disable these modes (I'm not kernel hacker).

No, if the rootds is on emmc after some time when this happens trying to
run any command they segfaults.
