Hello.
I'm contacting you because your email is listed in www.kernel.org/doc/linux/MAINTAINERS
I encountered a problem with the ahci-mvebu driver. I think it's a bug.
Hardware:
Areca ARC-5040 RAID enclosure (DAS), eSATA port, 8 SATA drive bays with 1x 500GB HDD stand-alone and 7x 2TB HDDs in RAID5.
Linksys WRT-1900ACS v2 router, Marvell Armada 385 (88F6820), one eSATAp using ahci-mvebu driver with port-multiplier support.
The router runs OpenWrt with kernel version 5.15.
Problem encountered:
Areca DAS is not detected properly. When I connect it, I get these repeating errors in kernel log:

The same errors appear if I leave it connected during reboot.
I tried to limit SATA speed to 150 and to disable NCQ from Areca admin interface. It didn't work.
I found no way of making it work.
The same router works perfectly when I connect a laptop HDD.
The same DAS, including the same eSATA cable, works perfectly when connected to an older
Linksys WRT-1900AC v1 with Marvell Armada XP (MV78230), using sata-mv driver.
This is the kernel log from the older router:

I'm not currently using the new router, so it's available for tests.

Can you try current mainline 6.1-rc kernel ? Not going to debug 5.15.
Debugging should be done on the latest kernel and any bug fix backported.

You mean an external single HDD connected with an eSATA port ?

What kernel version is running on that older Linksys box ?

This one seems OK with the PHY detection and it links up. Let me know the
kernel version and we can see what changed between the older kernel and
5.15. But you should still try latest 6.1-rc if possible.

OK. I have a bootable kernel v6.1-rc3, but no rootfs yet. I load it via tftp. I built it from github.com/torvalds/linux using OpenWrt toolchain. Bootlog is attached. At 17 seconds I connect the DAS.

Yes, to show that the hardware is not defective.

I don't think there is a change in kernel. It's just a diferent driver in use: ahci-mvebu vs. sata-mv.
BTW, is sata-mv compatible with this hardware? It won't auto-load instead of ahci-mvebu if ahci-mvebu is missing.
Thank you for your reply.

So the adapter & driver are OK for regular ATA devices but they may not
like port-multiplier devices, or one of its flavor. See:
https://en.wikipedia.org/wiki/Port_multiplier for a nice summary. PM
comes with either command-based switching or FIS-based switching. The
adapter may not support the flavor that your PM box uses, while the
sata-mv adapter does.

Try to check the router SATA adapter specs and your PM box spec and see
what PM flavor they support. If that matches, then this is likely a
driver issue. If they do not match, then nothing we can do. You will not
be able to use that PM box with your router.

There is a lot of info in Marvell Armada 38x Functional Specifications manual, but I don't
understand it. "FIS" is mentioned.
See https://ulli-kroll.de/Downloads/NAS326/A38x-Functional-Spec-PU0A.pdf , page 241.
From my kernel log:
ahci-mvebu f10a8000.sata: flags: 64bit ncq sntf led only pmp fbs pio slum part sxs
From https://ata.wiki.kernel.org/index.php/SATA_hardware_features
pmp means "port multiplier"
fbs means "FIS based switching"
Areca didn't write information so detailed in the manual, but it does say it supports NCQ,
so according to Wikipedia article you indicated, it probably isn't command-based switching.
Is there any way to get this info from the working router (sata-mv)? Or if I connect it to a desktop PC?

Yep, looks like the adapter does support FIS based switching. See table
1291 of that manual.

Yep. So the driver says it does support pmp & fbs, as expected from the
manual info.

For the working router, you should also be getting the same message that
you printed above, listing the flags of the adapter. On my test box, for
an Intel C620 series AHCI I have:
ahci 0000:00:11.5: flags: 64bit ncq sntf pm led clo only pio slum part
ems deso sadm sds apst
So no pmp nor fbs support. And for an additional Marvell PCI SATA
adapter on that same box that supports port multiplier, I have:
ahci 0000:61:00.0: flags: 64bit ncq pio
So no pmp nor fbs either. Yet, I have a 4-drive port multiplier box
connected with eSATA to that adapter, some random unknown vendor thing.
And weirdly enough, it works fine.
On a different test machine, an Intel Z170 chipset AHCI says:
ahci 0000:00:17.0: flags: 64bit ncq sntf pm led clo only pio slum part
ems deso sadm sds apst
No pmp/fbs again (No Intel adapter that I know support pmp). And an
ASMedia ASM1062 Serial ATA Controller add-on PCI card says:
ahci 0000:08:00.0: flags: 64bit ncq sntf stag led clo pmp pio slum part
ccc sxs
pmp is supported, but no fbs. I have a Logitech LGB-4BNHEU3 4-drives box
connected which does not seem to support fbs (the manual is useless
about that). It works fine, but when connected to the Marvel adapter on
the other box, it does not...
PMP is a mess and never really stabilized as faster USB interfaces
showed up at about the same time as eSATA tried to spread. That never
happened, and we are left with a bunch of devices that are hit-and-miss.
This of course does not mean that this is not a bug in the ahci-mvebu
driver. We can try digging into that. First thing to try: enable debug
messages in libata and libahci/ahci-mvebu. See
Documentation/admin-guide/dynamic-debug-howto.rst for that. Then connect
your eSATA box and see what it says.

This is likely because the adapter does not support or has a buggy
plug-an-play. The adapter needs to be power cycled/reset to detect changes
in drive connections. If you have libata & ahci drivers compiled as
modules, you could try rmmod them and then "modprobe ahci_mvebu".

Hmmm... No clue. This comes from sata_link_hardreset(). Would be good to
add messages in that function to see what fails causing the jump to the
error message print. Looking at ahci_mvebu_stop_engine() comments, there
seem to be issues (errata) with this controller.

It seems that sata_link_hardreset() fails in more than one way:

See sata_link_debounce() function comments:
* Make sure SStatus of @link reaches stable state, determined by
* holding the same value where DET is not 1 for @duration polled
* every @interval, before @timeout.
That function looks at the 3 lower bits of the SSTATUS register of the
AHCI port. These bits are defined like this:
0h -> No device detected and Phy communication not established
1h -> Device presence detected but Phy communication not established
3h -> Device presence detected and Phy communication established
4h -> Phy in offline mode as a result of the interface being disabled or
running in a BIST loopback mode
Given that your prints are showing up to bit 8, I am assuming you are
printing "cur" without the 0xf mask applied to it in sata_link_debounce().
So the high order bit "1" in the printed value is bit 8, part of the
Interface Power Management (IPM) bits. That bit indicates:
Device not present or communication not established
For the lower 4 bits, you have either "0", that is "No device detected and
Phy communication not established" and "1" sometimes, indicating "Device
presence detected but Phy communication not established"
SSTATUS is not stable and even when the "device detected" bit is set,
there is no PHY.
So something is going on at the hardware level here. The register value is
not stable... You could try playing with the sleep interval (unsigned long
interval = params[0];) and duration (unsigned long duration = params[1];)
to see if anything changes. Especially try reducing and increasing interval.

What are the defaults? Are these defaults the same for all sata/ahci controllers? How much can I increase them? Will anything break?
What could be the cause of this? sata cable? Power source?
BTW, while doing the testing, I saw the same error with the laptop HDD. I disconnected the cable and then reconnected it, and the second time it was detected OK. Unfortunately, I wasn't capturing serial messages and I couldn't make it happen again.

Nothing will break. No commands are exchanged during that link-up. It is
only phy initialization. The defaults are defined by
sata_deb_timing_normal or sata_deb_timing_hotplug at the beginning of
libata-sata.c. The names speak for themselves: normal timing is for device
scan on boot, hotplug for... hotplug :)

Could be the cable. Try to use a good quality short cable if you can.
Power source can be a cause too, but less likely. I have seen lots of
issues with bad cables, but they generally manifest themselves under load
with transfers with bad ECC. When it happens, the errors are obvious.
Could be the plugs too. Check for dust and/or lose connection with the cable.

I checked the cable and connections. Everything looks OK. The cable is ~ 40cm
long.
I made these timeout changes:
const unsigned long sata_deb_timing_normal[] = { 5, 1000, 20000 };
const unsigned long sata_deb_timing_hotplug[] = { 25, 5000, 20000 };
And I have these results:

Can it be a hardware init / setup problem? In the Armada 38x Functional
Specifications there is a chapter about "Amplitude and Pre-emphasize level" at
the end of SATA.

So the hardware is failing to detect the device presence. No clue why.
Only an ATA bus trace could tell us more here (do you have an ATA bus
analyzer around ?).
So options are:
1) Involve the router vendor and/or SoC vendor to see if they can help.
2) Use UDB connection between your router & drive box ? (if you can)
Another thing is: Did you try earlier kernel versions ? Any earlier kernel
working ? (I forgot if that is the case). If yes, then we should be able
to figure out the change that broke the driver (which may be something
changed in the SoC support rather than the mvebu driver itself).
gi-bisect will likely not be of any help given that you are not getting a
crash. So you will need to try out different kernel versions, starting
with LTS kernels, and refine (use Linus tags, including RCs, to find the
last working kernel). That may take some time, but will likely narrow down
the search for fixing this (if that is possible given the hardware setup
you have).

It could be. See above about searching for a working kernel version, if

Hello! Sorry for jumping into this discussion but I think it could be
useful for you to know that Armada 38x and 39x SoCs have HW errata
related to their SATA PHYs and SATA port replicators. Due to the wrong
Busy status returned, the GEN 1.0 Port Multiplier cannot establish a
link with the SATA 3.0 interface. As a workaround connect GEN 1.0 Port
Multiplier to a SATA 2.0 interface. Native A38x/A39x SATA IP is
controlled by ahci-mvebu linux kernel. I do not have any other details
if broken is SerDes / PHY block in that SoC or SATA block. But error
"cannot establish a link" may be related to that documented A38x/A39x
SATA HW errata. Note that older Marvell SoCs (Armada 375, 370) have also
some different SATA HW erratas related to link establishment, so in my
opinion there could be some common undocumented root cause with SATA in
all those 32-bit Marvell SoCs, as lot of HW blocks are shared, and not
only related to port replicators. I have never played/debugged SATA
issues on A38x but I observed similar issues with PCIe on A38x. And due
to nature of Common PHY HW blocks implementing same SerDes interface for
both PCIe and SATA PHYs on those SoCs, I would not be surprised if PHY
issues could be present on both PCIe and SATA functions.

Sorry for the late reply, but I really really hate bisecting, especially manually, and especially if the test must be run on another machine.
You are correct. It initially worked, but it was broken by this commit:
commit 2dc0b46b5ea30f169b0b272253ea846a5a281731
Author: David Milburn <dmilburn@redhat.com>
Date: Tue Nov 14 16:17:25 2017 -0600
libata: sata_down_spd_limit should return if driver has not recorded sstatus speed
During hotplug, it is possible for 6Gbps link speed to be limited all
the way down to 1.5 Gbps which may lead to a slower link speed when
drive is re-connected.
This behavior has been seen on a Intel Lewisburg SATA controller
(8086:a1d2) with HGST HUH728080ALE600 drive where SATA link speed was
limited to 1.5 Gbps and when re-connected the link came up 3.0 Gbps.
This patch was retested on above configuration and showed the
hotplugged link to come back online at max speed (6Gbps). I did not
see the downgrade when testing on Intel C600/X79, but retested patched
linux-4.14-rc5 kernel and didn't see any side effects from this
change. Also, successfully retested hotplug on port multiplier 3Gbps
link.

I do not have more details than what I already wrote in previous email.
Errata documents are in most cases available on Marvell Customer Portal.
You need to register for accessing them. https://www.marvell.com/portal
Documents which were available publicly without registration are here:
https://www.kernel.org/doc/html/latest/arm/marvell.html
(errata for a38x was not publicly available)

I think I'll wait for an opinion from Damien. Since the same libata-core.c works perfectly fine with sata-mv driver, but not ahci-mvebu, the problem might still be in the ahci-mvebu. The comment said: "sata_down_spd_limit should return if driver has not recorded sstatus speed". This probably means that ahci-mvebu does not record the expected "sstatus speed". I don't know what that is, but Damien probably does.

There is a slim chance that I could understand them. I'm just an amateur. I did some bare-metal programming on MCUs, but the kernel is way too complicated for me.

That is also possible. But existence of a38x sata specific errata smells.

Lets wait for Damien.
Also note that in kernel ahci_mvebu.c driver code is custom function
ahci_mvebu_stop_engine where is description of another Errata Ref#226 -
SATA Disk HOT swap issue when connected through Port Multiplier in
FIS-based Switching mode.
This errata is documented _only_ for A3720 (not A38x/A39x) but is
installed for all mvebu platforms. So I'm not sure if this is not
another kernel bug and code should be adjusted to _not_ install
ahci_mvebu_stop_engine for a38x/a39x.

Hehe... those documents lot of time contains incomplete or ambiguous
statements and also professionals cannot understand them...
As I wrote in previous email, errata Ref #: FE-8889968 just says:
Due to the wrong Busy status returned, the GEN 1.0 Port Multiplier
cannot establish a link with the SATA 3.0 interface. As a workaround
connect GEN 1.0 Port Multiplier to a SATA 2.0 interface.
And I'm not SATA expert too. Lets wait for Damien.

Attending OSS Japan conference Monday & Tuesday, so I will be able to look at
this second half of this week. Given this latest information, there are a couple
of things we can try I think.

Without reverting the above patch, could you please try the following patch ?
diff --git a/drivers/ata/ahci_mvebu.c b/drivers/ata/ahci_mvebu.c
index 22ecc4f3ae79..396aacc3fbd1 100644

if (rc)
goto disable_resources;
This essentially disables the use of ahci_mvebu_stop_engine() function for
your adapter, that is, it assumes that your newer adapter is not subject
to errata Ref#226. If this helps, then we can have a cleaner fix using the
compatible string for the adapter/SoC.
Otherwise, we will need to add a quirk for this adapter to have a behavior
for it that is the same as if patch 2dc0b46b5ea3 is reverted.
By the way, what is the maximum speed of you pmp box ? Is it really 1.5
Gbps (sata gen 1) ?

No. It's 3 Gbps.

I did more tests, with and without the patch, with and without the commit reverted.
All logs start when eSATA cable is connected. I didn't include boot logs.

As you can see, it doesn't work. But I noticed something:
With commit reverted, initially it's not working and, after a reset, sets speed to 1.5Gbps and then the port multiplier is detected. When each port is scanned, speed is set to 3.0 Gbps and it works fine like that.
If the commit is NOT reverted, SATA speed is never limited and port multiplier is never detected.
--- commit reverted, no patch ---

So, is this a quirk of the mvebu controller or the Areca DAS? BTW, Areca uses some mvebu SOC too.
I'm going to try the Areca DAS with a few other controllers. I want to see what happens.

Hmmm... OK. Given that when it works (with the revert), the speed
reduction is to 1.5 Gbps. So it seems that the revert changes the error
return into checking the lowest speed because we do not already have a
previous speed... See below.

Can you try with no patches and no revert adding the following options to
your kernel command line ?
libata.force=2:3Gbps
and
libata.force=2:1.5Gbps
One at a time. Do not try them together :)
This will force the initial link speed to be set for ata2 port.

By the way, did you also try a cold boot ? Switching off your router,
connect the pmp box, turn on the router ? Does it change anything ?
ATA hot-plugging tends to have more problems, so worth trying. The
ahci_mvebu driver errata is for hot-plug, so this newer SoC may have
different issues with that too.

Yes. No change. Same errors.

No change. Same errors.

This one works, without any error at the beginning, unlike the way reverted commit worked.

Note that the kernel command doesn't seem to actually limit the speed.

Just to make it clear, errata Ref#226 is for Armada 3720. Armada 385 is
32-bit and is _older_ product than 64-bit Armada 3720. Marvell naming
convention is... well unintuitive.
In my opinion Marvell tried to fix A385 errata Ref#FE-8889968 in its new
A3720 product but broke something different which introduced a new HW
errata Ref#226.

Interesting. So it looks like the adapter does not like speeds above
1.5Gbps, at least with pmp/fbs... When connecting a regular 3 or 6 gbps
HDD (sata-2 or sata-3), do you get higher speeds ?
So the temporary workaround is to use "libata.force=2:1.5Gbps" on the
kernel command line. For a better fix, we need to figure out why higher
speeds do not work... Difficult one. Let me have another look at the specs
& driver again. Might take some time though.

ah ! I thought the reverse :) Indeed not intuitive...

Checking the specs for the SoC again, it does say:
Gen3 Serial ATA PHY (6 Gbps) with speed negotiation to Gen1, Gen2
So with your gen2 (3gbps) pmp box, clearly, the speed negotiation is not
working but limiting it to 1.5gbps seems ok. Could you add the following
print to see what the HW is saying it supports ?

Without libata.force=2:1.5Gbps, the extra debug message appears only during boot.

I had the impression that speed always starts low and is negociated up (1.5 -> 3 -> 6), not starting high and decreased. How would negociation work if the speed is too high and one of the devices can't communicate?
I tried the pmp box on other computers. ATI/AMD AHCI, Jmicron PATA/SATA combo card, Intel ICH7. None of these have any errors in the log.

OK. So the HW is saying that it has no restrictions on the link speed.
From AHCI specs, bits 07:04 of SCR CONTROL (SControl) mean:
0h No speed negotiation restrictions
1h Limit speed negotiation to Generation 1 communication rate
2h Limit speed negotiation to a rate not greater than Generation 2
communication rate
3h Limit speed negotiation to a rate not greater than Generation 3
communication rate

First of all, understand how PMP works: the adapter must first detect that
it is dealing with a port multiplier box, not an actual device. But on
startup, it does not know that yet and so link speed negotiation is done
with the box. Once that is done and a "PMP" device type detected, the link
speed may be changed to the lowest speed of all the devices in the box so
that the adapter can communicate with all of them over the same link.

OK. So by limiting to 1.5gbps, detection works and the adapter detects the
PMP device. The driver then goes on to probe all ports present on the PMP.

Here, the speed is limited to 1.5gbps for all ports because the kernel
option limited the link to that speed. SCR control == 0x300 means
"Transitions to both Partial and Slumber states disabled"... Hmm. May be
this is what we need: no LPM.

Not sure why it resets again here... Might be the COMRESET needed for PMP
before probing the ports.

So now the PMP box speed is negotiated at 3gbps at it should have in the
first place. Weird. The option should still force limit it to 1.5gbps...

And the first port gets 3gbps too.

The speed will start at the highest auto-negotiated speed, at the HW
level. The ahci driver will however lower it if it sees errors during
probe and try probe again with the lower speed.
What I do not understand here is why after the second reset we get 3gbps.
The libata.force parameter seems to be ignored and auto-negociation
working, detecting the pmp at 3gbps. Need to dig into that...
In the mean time, can you try this kernel boot option:
libata.force=2:nolpm
without the "2:1.5Gbps" option.

sata_link_hardreset(), inside if(sata_set_spd_needed(link)){} condition,
but I replaced it with detailed debug inside sata_set_spd_needed() and ___sata_set_spd_needed()
I ran the tests again with the new debug messages.
These are kernel boot logs with eSATA cable already connected.
I selected only the interesting lines to make it easy to read.

Could you try adding messages in the function sata_down_spd_limit() ?
I recall that during probe, scr status does not give a current speed,
which creates the problem of triggering that "return -EINVAL" in the else
for "if (spd > 1)"...
What I would like you to print is:
diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c

spd = (sstatus >> 4) & 0xf;
- else
+ pr_info("spd from STS: 0x%0x\n", spd);
+ } else {
spd = link->sata_spd;
+ }
mask = link->sata_spd_limit;
if (mask <= 1)
Please try printing that in addition to the messages you already have. And
please try with default boot (no ata options) and with the 1.5gbps force
(since that is the only one working).

Can you share the patch/diff printing these ? Just to be sure I look at the
right place :)

OK. And here is the problem: cur spd is 0x0, so unknown, and that leads to an
einval exit of sata_down_spd_limit() instead of trying something sensible like
starting with 6Gbps. That leads sata_set_spd to also have cur spd = 0 and
setting of a bad scontrol which prevents detecting the drive. See the difference
with forcing 1.5gbps:

We have a good SCR thanks to spd being set to 1 = 1.5 gbps.
So patching sata_down_spd_limit() is the right solution I think. Let me cook
something for you to test.

Thanks for that. Unfortunately, my PMP box is currently disconnected from
my test machine in the lab. Need to get there to reconnect it :)
But I think I got an idea of what is wrong here. Can you try this patch:
diff --git a/drivers/ata/libata-sata.c b/drivers/ata/libata-sata.c
index 18ef14e749a0..cb12054c733f 100644

if (limit == UINT_MAX)
- target = 0;
+ /* Try highest gen 3 limit */
+ target = 3;
else
target = fls(limit);
Note that with further digging, it seems that even for a working system
with all drives detected, we always end-up with something like:
cat
/sys/devices/pci0000:00/0000:00:17.0/ata6/link6/ata_link/link6/sata_spd_limit
<unknown>
And same for hw_sata_spd_limit.
So the UINT_MAX blind initialization of the speed limit before probing
seems to never be corrected and set to the actual limit of the
link/device. That needs further correction. But for your case, the above
should fix the issue I think.

Sorry to interfering in from the side, but I have observed very similar behavior with a Marvel 88SE6121 controller (AHCI kernel module): Very old SATA-1 HDDs (mostly laptop HDDs in my tests) work flawlessly, SATA-2/3 HDDs consistently fail. Limiting SATA speed (libata.force=1.5G ...) does not help.
Interestingly, SATA-2/3 HDDs do work with U-Boot and 'ancient' 3.x kernels. There was a suspicion that it was the PCI subsystem (the change in kernel 3.16 from kirkwood/pci.c to mvebu-pci). Pali Rohár did a great job to investigate this problem very persistently, but in the end we did not find a solution.
Without knowing anything about this area, there was the assumption that the problem must be at one of the lower levels close to the hardware.
You can find all the details and a lot of protocols in Bug https://bugzilla.kernel.org/show_bug.cgi?id=216094
I've been trying to revive my NAS440 for over 10 years with all the components (https://github.com/hn/seagate-blackarmor-nas), so I have the hardware available and am happy to persevere to try things or otherwise help.

Well, the first thing to do would be to test your system using the latest
kernel 6.2-rc5 and see if the problem still exists. If it does, please
report the issue.

It doesn't work. I didn't really expect it to work, since manually forcing 3Gbps didn't work either - probably a hardware issue like you said.
I think that the old behaviour (before commit 2dc0b46b5ea30f169b0b272253ea846a5a281731) of slowing down sata speed when a connection can't be established is in fact the right thing to do. Maybe a longer delay before reducing the link speed would satisfy the random cases that the commit author reported. Maybe he was just having a loose connector issue - especially since he only reported one case.

Well, this one was not intended to limit the link speed to anything.
target == 0 written to scontrol means "no autonegociation speed limit",
while target == 3 means "limit autonegotiated speed to gen 3", which are
effectively equivalent since the max speed is gen 3 :) The point was to
force an scontrol write: in your case, spd is 0 and the default code with
target == 0 ends up with __sata_set_spd_needed returning false and so
sata_set_spd() doing nothing. Setting target to 3 forced trying to set the
speed to gen3. Wanted to see what that did.
Given that things are working by forcing 1.5gbps, and you endup with the
correct 3gbps link speed, it seems that this hardware does not like
negotiation starting from the highest speed. The SATA-IO specifications do
clearly mandate that adapters should allow for any initial speed, the
highest or the lowest and be ready for negotiation from any starting
combination of device and adapter speeds. But it seems that the designers
of this adapter and/or of the pmp box missed that chapter :)

I do not think that a longer delay will change anything in your case since
the device presence cannot be established when starting speed negotiation
without a limit: see the "debounce, SCR=0x100" messages in your debug,
while the 1.5gbps link speed forcing leads to an immediate device presence
detected (debounce, SCR=0x113 message).
Can you please try this one:

spd = link->sata_spd;
+ }
mask = link->sata_spd_limit;
if (mask <= 1)
If that does not work, we'll have to handle your case with a HORKAGE flag
for that adapter.

I was referring to the original "bug" the commit author (David Milburn) was trying to fix.

Hi. It's me again.
May I bother you with another bug? (^_^;)
The machine is a Lenovo X61 Tablet, a tablet PC with Intel GM965 / ICH8-M.
It has a cardbus slot (32bit PCI), Ricoh RL5C476 II (VEN_1180 DEV_0476).
The card is a VIA VT6421 (VEN_1106 DEV_3249) SATA/PATA controller.
The card has 2 SATA ports and no PATA.

Beuh... libata does not understand these status. Bit 3 is set in the
status, but that one is transport dependent, so defined in CF card...
Would need to look that up, but it seems to be that the device reports
that an PIO is still on-going. It seems like we are in the realm of "this
is a weird drive". You could try increasing the 10ms timeout in
ata_wait_idle(): change the call:
ata_sff_busy_wait(ap, ATA_BUSY | ATA_DRQ, 1000);
to something like:
ata_sff_busy_wait(ap, ATA_BUSY | ATA_DRQ, 5000);
to see if that changes anything.

Looks like a problem with interrupts here. Can you "gdb vmlinux" and "list
*(cpuidle_enter_state+0xbb)" to see exactly what is failing here ?

Looks like the ATA_PFLAG_UNLOADED is not set, causing this warning. But
given that there seem to be issues with interrupts, the eject may not be
detected.

Marius,
Thanks again for testing.
Could you try a new variation of the fix shown below ? This newer fix
should avoid uselessly going down to 1.5 Gbps as shown above.
Thanks !

OK. That is because the limit is not being changed with the added "return 0".
What about this version:

OK. So it seems that your adapter really wants the initial scan at 1.5 Gbps...
Since the initial tweak worked, I will post the official patch for it. I will CC
you. Please retest to be sure and send a "Tested-by:" tag ! Thanks !

Apologies for asking you to test again, but could you try this simpler
version of the initial tweak:
diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c

*/
if (spd > 1)
mask &= (1 << (spd - 1)) - 1;
- else
+ else if (link->sata_spd)
return -EINVAL;
/* were we already at the bottom? */
This is a partial revert of the commit that created the issue in the
first place. But better check this is OK.

No problem. I'll test everything until you find the best possible fix for the kernel.

Perfect. I prefer this version of the fix as it actually does *exactly* what the
comment above the if/else hunk says, that is not force 1.5gbps speed if we
already have a recorded speed. But in your case, we do not have a recorded speed
(link->sata_spd == 0), so retrying with 1.5gbps is the right thing to do.
I will write a nice commit message and post.
Thanks for testing.

I sent the official patch and CC-ed you. Can I add your
"Tested-by: Marius Dinu <marius@psihoexpert.ro>" tag to the patch and queue it ?

Yes, I was planning to reply myself, but I'm not done testing yet. At this point I can only say it's working on mvebu / Armada 385. I plan to backport to v5.15 and test with the other router that I have (mvebu / Armada XP), a laptop and two x86_64 desktops, one of which has various PATA and SATA controllers in all sorts of weird configurations. I hope to do it all this weekend.
Thank you for the patch!

I did testing on Intel & AMD machines with different adpaters/drives/pmp that I
have (AHCI, ASMedia and Marvell adapters). Everything was OK on my end.
The tag is for this kernel only. If backporting to 5.15 does not solve the
issue, we will need to take that separately and redo debugging on that version.
I would like to send the patch to Linus by the end of the week...

I saw that the patch was applied to v5.15 too. That was probably not a good ideea. This weekend I tried to test the patch in OpenWrt kernel v5.15. It doesn't work:

...and these two lines repeat forever. There is no "giving up".
I tried the workaround "libata.force=2:1.5Gbps". It works, but with a delay:

So probably some other commit needs backporting before this one works. Any ideea which might it be?
I will try another bisect when I have time. Any clues would help a lot.

EPIPE is supposed to be to tell the upper layer to lower the speed...

...which here ends up not looking good as the speed limit is still UINT_MAX, so
unknown for that drive. So I guess that for 5.15, we need to fix not only the
current speed, but also the speed limit.

And then here, automagically, the libata.force limit seem to kick in... Very weird.

That is weird too. No point in repeatedly resetting if the link is up. So the
patch really screwed up something for 5.15.

Nothing weird here. There is one reset for each logical port. Only two ports are used.
I'm going to insert the debug messages in this kernel version too and test again.

Ah! missed the port number changing :) You are right.

Thanks. Did you test the other LTS 6.1 kernel too ? The patch was backported
there too.

I tested the patch applied to github tags "v6.1" and "v5.15". They both work fine.
I build another OpenWrt image and it doesn't work. I don't know why and it's difficult to add modifications into OpenWrt kernel, because the kernel sources don't persist. The build system erases everything, unpacks fresh kernel sources and then patches them. To make any modification I have to add .diff files into the patches dir and build again, write the new firmware into the router flash, test, etc. It's very slow.
I think I'm going to leave it as it is and limit the speed from the kernel command line until OpenWrt updates the kernel.
Thank you for your help.

OK. Sounds good. Thanks a lot for testing.
