Kernel oops when updating CVS firmware

[hughsie]

On my unreleased Dell ARL-based laptop I was able to do sudo fwupdtool --plugins intel-cvs install-blob 06CB0701.bin -vv which made the progress bar move encouragingly. When the update had reached 100% of the write:

FuStructIntelCvsStatus:
dev_state: 0x16
fw_upd_retries: 0x5
total_packets: 0x1dd1
num_packets_sent: 0x1dd1
fw_dl_finished: 0x0
fw_dl_status_code: 0x0

... then looking at sysfs, the /sys/devices/pci0000:00/0000:00:14.0/usb3/3-4/3-4:1.0/usbio-i2c.21.auto/i2c-14/i2c-INTC10E0:00 device went away, and then "came back" a few seconds later, where fwupdtool then froze. I saw this in dmesg:

It looks to me like some kind of refcounting problem -- as soon as the new i2c device appears fwupd queries the cvs_ctrl_data_pre file for the new version -- which seems to make the kernel explode -- and any subsequent access to /sys/devices/pci0000:00/0000:00:14.0/usb3/3-4/3-4:1.0/usbio-i2c.21.auto/i2c-14/i2c-INTC10E0:00 causes the same uninterruptable freeze of the fwupd daemon. Ideas?

Hi Richard,

The issue is due to use of Auxiliary Bus in USBIO. If we use AUX, then we are closing old i2c and creating the new i2c, in this case old i2c was not close properly and new USBIO was not sure which one to use. Due to inconsistency/timing we got memory leakage.

I have created issue on USBIO drivers.

Hi Richard,
To get past this issue, we have been working on a new USBIO stack that does not utilize aux bus. Currently, we are still undergoing internal review before we push it upstream, so hence we couldn't get you a clean version. Below is the branch that contains the changes being reviewed.

For FW download to work with this new USBIO stack, there is a change needed from the FW side to get it working. But for the time being, you can apply the below change on the driver side, on top of the above link I shared and be able to upgrade your FW.

Let me know if it works okay for you. Will share an official version once we have the fixes in.

Hi Sid. When using ioext-main branch I only get:

  CC [M]  drivers/usb/misc/usbio.o
/tmp/ccqLUhQU.s: Assembler messages:
/tmp/ccqLUhQU.s:7: Error: junk at end of line, first unrecognized character is `U'
/tmp/ccqLUhQU.s:8: Error: junk at end of line, first unrecognized character is `U'

The out-of-tree module works fine with the main branch. This is on a fully up-to-date Fedora 41.

we are still undergoing internal review before we push it upstream

Maybe you can pass up your management chain that this "internal review" process that everything seems to be afflicted by is making it very hard to work together in the open source ecosystem. At this point I have three out-of-tree modules, all of which on specific branches, two of which with manually applied patches -- and still the camera firmware can't update. It's essentially farcical at this point for devices that are shipping to users already.

Issue pops up when you use gcc-9.x for kernel and gcc-13.x for building usbio.o module. Sid will confirm if gcc-13.x is used to build kernel and firmware will resolve this issue. Please refer to attached build snapshot which has same error.

[hughsie]

My kernel was built with gcc 14.2.1 and I'm using the same gcc 14.2.1 for the module.

[karesidd]

Hi Richard,

I'm noticing the issue when building with gcc-12 and beyond. It seems to be okay with gcc-11. I tested it with kernel 6.12 and had gcc-11 in my setup so i didn't notice this issue. I've narrowed it down to this commit -> gpio: adding gpio-usbio

Not exactly understanding what the issue is, so I've been commenting out code to see if it compiles. Will keep you posted and update the branch once I resolve.

Regarding your comment about having to deal with side patches and branches, unfortunately the usb max packet descriptor change is supposed to be coming from the firmware vendor, and so this was just to temporarily unblock you.

Regards,
Sid

Hi Richard,

I'm able to compile on Fedora 41, with gcc 14.2.1 without any issues. Fedora 41 came with kernel 6.11. What is your kernel version?

[hughsie]

I'm using kernel 6.13.9-200.fc41.x86_64 -- you need to sudo dnf update -y to update to the latest versions of everything.

[karesidd]

Hi Richard,

This PR -> intel/usbio-drivers#36 will fix the above issue. Will get it reviewed and integrated.

Regards,
Sid
