emu1010k firmware does not properly load in 13.04 with kernel 3.8.0

[Eriks Dobelis]

emu1010k firmware does not load in 13.04 with kernel 3.8.0.
With kernel 12.10, kernel 3.5 it was working, but to make it properly load after hibernation I had to compile it into kernel with:
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="emu/emu1010b.fw emu/micro_dock.fw emu/hana.fw"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

With 3.8.0 it neither loads from the start, nor after hibernation even with above lines compiled into kernel. Log files don't show error, but repeat msg on loading firmware. Once in few seconds everything freezes momentarily. If I switch off the dock, then it does not freeze (and obviously card does not work).
If I boot into Windows and reboot into Ubuntu, card works ok (as Windows probably load firmware, I didn't switch off the external dock during reboot).

I have found somewhat similar bug in ArchLinux for kernel 3.8.6 and related soundcard: https://bugs.archlinux.org/task/34865 , which was said to be fixed in 3.8.8.

From dmesg grepping on emu:

[ 18.761448] emu1010: Special config.
[ 18.761565] emu1010: EMU_HANA_ID = 0x3f

[ 20.886776] emu1010: Card options = 0x8
[ 20.887270] emu1010: Card options3 = 0x8

and later:

etc., etc.

I have exactly the same problem.

One thing to note is that if you read the dmesg log without grepping, there is a line right after every "emu1010: Audio Dock Firmware loaded" line stating the Audio Dock version is "0.0", meaning that the module is failing to read both major and minor version numbers.

Also, I found a work around that at least works for me.
1. Reboot to kernel 3.5.x using GRUB
    The firmware should load without problem
    (although nothing else works because everything is built against 3.8 kernel)
2. Don't turn off the micro dock and reboot back to kernel 3.8

It seems that as long as I don't turn off the dock, it keeps working even after system reboot/shutdowns.

I have emu 1616m PCI card.

Apparently booting 3.5.x achieves something similar as booting Windows.

This is how dmesg looks after I have booted Windows, rebooted into Ubuntu with kernel 3.8. As I wrote, in such case everything works. Interestingly Card options is 0x4 instead of 0x8. And there are no lines with audio dock firmware loading.

[ 18.169454] emu1010: Special config.
[ 18.169572] emu1010: EMU_HANA_ID = 0x3f
[ 18.169573] emu1010: firmware file = emu/emu1010b.fw, size = 0x11bdc
[ 20.310378] emu1010: Hana Firmware loaded
[ 20.310424] emu1010: Hana version: 1.6
[ 20.310481] emu1010: Card options = 0x4
[ 20.310504] emu1010: Card options = 0x4
[ 20.311001] emu1010: Card options3 = 0x4

Is there some tool to manually control loading of the firmware? Any debugging info that could be switched on? Anybody has tried 3.8.8 or 3.9 with Ubuntu 13.04?

[Eriks Dobelis (eriks00)]

Nick, can you post dmesg when you boot into 3.5?

[Eriks Dobelis (eriks00)]

I briefly looked into code. I found out that options seem to be correct:
#define EMU_HANA_OPTION_DOCK_ONLINE 0x04 /* Audio Dock online and FPGA configured */
#define EMU_HANA_OPTION_DOCK_OFFLINE 0x08 /* Audio Dock online and FPGA not configured */

Also, EMU_HANA+DOCK_ID = 0x15 is the only value that is considered as success after trying to load microdock firmware.

On EMU_HANA+DOCK_IRQ_STATUS = 0x0 I have no idea what shall it be normally at this point. These are the values from header file:
#define EMU_HANA_IRQ_WCLK_CHANGED 0x01
#define EMU_HANA_IRQ_ADAT 0x02
#define EMU_HANA_IRQ_DOCK 0x04
#define EMU_HANA_IRQ_DOCK_LOST 0x08

Not being able to read dock major and minor rev does not sound good. Apparently firmware is not loaded successfully. No further ideas where to look.

Thanks to Tobias Powalowski I found this:
https://projects.archlinux.org/svntogit/packages.git/tree/trunk/alsa-firmware-loading-3.8.8.patch?h=packages/linux
I'll check it out later.

[Eriks Dobelis (eriks00)]

I applied the patch to Ubuntu kernel 3.8 and the problem seems to be gone, at least it booted once.

[Eriks Dobelis (eriks00)]

I've been using it for couple of days without problems. Recommend for anyone experiencing the same problem.
