Re: BU40N Blu-Ray drive not working with latest kernel

Hm this doesn't give any new information @loqs Should I just send the bugreport and you reply with the patch that we have already tried?

Re: BU40N Blu-Ray drive not working with latest kernel

Could you build a kernel with the patch applied to rule out a build error on my part?

Re: BU40N Blu-Ray drive not working with latest kernel

Could you retest the following? This is again with the patch from @loqs applied:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-6.12.8.arch1-1.1-x86_64.pkg.tar.zst

Note that this is a patched version of the linux package now, and not linux-mainline anymore. So please verify that you have booted the right thing by running "uname -r"

6.12.8-arch1-1.1 built by gromit the drive doesn't work.

Re: BU40N Blu-Ray drive not working with latest kernel

@gromit that rules a build issue out so can you include the failing patch in the upstream report? I would just be guessing why the quirk is not working as expected at this point.

Re: BU40N Blu-Ray drive not working with latest kernel

Could you also post the output of the following?

hdparm -I /dev/sr0

Well mine is in an enclosure so it just gets the enclosure

/dev/sr0:

ATA device, with non-removable media
Standards:
	Likely used: 1
Configuration:
	Logical		max	current
	cylinders	0	0
	heads		0	0
	sectors/track	0	0
	--
	Logical/Physical Sector size:           512 bytes
	device size with M = 1024*1024:           0 MBytes
	device size with M = 1000*1000:           0 MBytes 
	cache/buffer size  = unknown
Capabilities:
	IORDY not likely
	Cannot perform double-word IO
	R/W multiple sector transfer: not supported
	DMA: not supported
	PIO: pio0 

I set a udev rule for "max_performance" and it works fine now. For some reason around kernel 6.12.4 or 5 it is setting my desktop as a laptop and setting "med_power_with_dipm" for power management, Which is also when the problems seem to have started for me.

Re: BU40N Blu-Ray drive not working with latest kernel

@Alesar1 could you upload a dmesg for the mainline kernel with the patch applied?

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.13rc6-1.1-x86_64.pkg.tar.zst

Re: BU40N Blu-Ray drive not working with latest kernel

Thanks for posting the logs, it's always awesome to work with people who respond quickly! ^_^

@loqs, upstream also said that the patch should be good as-is, let's see what the further investigation brings up!

Re: BU40N Blu-Ray drive not working with latest kernel

@Alesar1 could you also upload a dmesg from 6.13.0-rc6-1.1-mainline-dirty with the kernel parameter ahci.mobile_lpm_policy=1 in case upstream wants a dmesg showing the correct detection of the drive.

Ugh, what is this? I'm quite confused ...

I'll add this information to the upstream thread

Re: BU40N Blu-Ray drive not working with latest kernel

@loqs could it be that it is actually not the blueray player that needs the quirk but the host controller?

Re: BU40N Blu-Ray drive not working with latest kernel

Alright, upstream got back to us with an additional debug patch (from https://lore.kernel.org/all/Z4U-rc3VUeegHGAg@ryzen) that I have applied to the following kernel:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.13rc7-1.1-x86_64.pkg.tar.zst

It would be good if you could test it (with no modification of the kernel commandline) and see if this makes the device work and post the dmesg in any case.

Re: BU40N Blu-Ray drive not working with latest kernel

No, it doesn't work.
It looks like the drive doesn't show up in dmesg until (and unless) I open it using the button on it. (when the drive is used with a working kernel).

As you can see above, the drive is loaded after >300 seconds. (this log comes from the LTS kernel).

Here's the log using Linux version 6.13.0-rc7-1.1-mainline-dirty : https://0x0.st/8oiE.txt

Re: BU40N Blu-Ray drive not working with latest kernel

@Alesar1 could you run the previous 6.13.0-rc7-1.1-mainline-dirty kernel again and wait for a while (dunno maybe 5-10 min) to see if we also get the "ata4: SATA link up" there after a while?

Re: BU40N Blu-Ray drive not working with latest kernel

Alright, we have a new debug patch, please test (maybe also for 5-10 minutes) and post the dmesg:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.13rc7-1.2-x86_64.pkg.tar.zst

Re: BU40N Blu-Ray drive not working with latest kernel

I tested 6.13.0-rc7-1.2-mainline-dirty and waited 10 minutes, but nothing showed up, I then pushed the eject button on the drive, but I got nothing on dmesg.

Re: BU40N Blu-Ray drive not working with latest kernel

Quoting from https://lore.kernel.org/linux-ide/Z4f_5 … ppL@ryzen/

Short story:
I was thinking about this a lot, and unfortunately I came to the conclusion
that we cannot with good conscience write such a workaround.

The reason is that we would increase the power usage on all SATA ports that
have no devices connected to them at boot, not just for his controller, but
for all SATA controller all around the world, just to have a workaround for
this non-spec compliant SATA Blu-Ray player.
(The reason is that would not be able to offline the port, which will shut
down the PHY).

I suggest that your user simply does:
# echo max_performance > /sys/class/scsi_host/host3/link_power_management_policy
or
$ sudo sh -c "echo max_performance > /sys/class/scsi_host/host3/link_power_management_policy"

Does the suggested solution work for those affected? Please also see the long story in the link.
