The board code has this sound/soc/intel/boards/bdw-rt5677.c:285: .codec_name = "i2c-RT5677CE:00", It's clearly a match to ACPI enumerated I2C slave device.

I suspect that the ACPI data here is less-than-optimal (but it does have the latest underlying chromeos update). If you tell me what to run I can poke the data and confirm. Thanks!

After looking at 89128534f925 (which introduced the above line, and thus support for the Chromebook), I think that 36afb0ab648 and 55e59aa0525a are wrong and should be reverted. It seems like they're an attempt to make 89128534f925 be done 'properly' but it also seems like the Chromebook is the only platform in question that triggers that code and it results in a NULL pointer dereference, so it's a regression on the only platform that makes use of the code paths in question. I'd also be happy to try a patch on top of master to see if that resolves things. The oops in question looks like: BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 IP: rt5677_i2c_probe+0x4a/0x730 [snd_soc_rt5677] PGD 0 P4D 0 Oops: 0000 [#1] SMP Modules linked in: snd_soc_rt5677(+) btusb(+) btrtl iwlwifi(+) snd_soc_rl6231 btbcm snd_ CPU: 1 PID: 403 Comm: systemd-udevd Not tainted 4.12.0-rc1ph+ #119 Hardware name: GOOGLE Samus, BIOS 04/02/2015 task: ffff947de8ca1cc0 task.stack: ffffaf5641fe0000 RIP: 0010:rt5677_i2c_probe+0x4a/0x730 [snd_soc_rt5677] RSP: 0000:ffffaf5641fe3b30 EFLAGS: 00010246 RAX: ffff947de8e02618 RBX: ffff947de8e02618 RCX: 0000000000000000 RDX: 0000000000000001 RSI: 0000000000000286 RDI: ffff947dec7ece98 RBP: ffffaf5641fe3b68 R08: ffff947dfec9bda0 R09: ffff947de8e02600 R10: ffff947dfec9bd20 R11: ffffd7ef91a12180 R12: ffff947dec7ecc20 R13: ffff947dec7ecc00 R14: 0000000000000000 R15: 0000000000000000 FS: 00007f9bd7fdb8c0(0000) GS:ffff947dfec80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000018 CR3: 000000046872b000 CR4: 00000000003406e0 Call Trace: ? acpi_dev_pm_attach+0xa4/0xe0 ? rt5677_to_irq+0xe0/0xe0 [snd_soc_rt5677] i2c_device_probe+0x17c/0x230 driver_probe_device+0x2a1/0x460 __driver_attach+0xd8/0xe0 ? driver_probe_device+0x460/0x460 bus_for_each_dev+0x58/0x90 driver_attach+0x19/0x20 bus_add_driver+0x40/0x270 driver_register+0x5b/0xe0 i2c_register_driver+0x3b/0x80 ? 0xffffffffc072b000 rt5677_i2c_driver_init+0x17/0x1000 [snd_soc_rt5677] do_one_initcall+0x4c/0x1a0 ? kmem_cache_alloc+0xf7/0x150 do_init_module+0x56/0x1e8 load_module+0x1f54/0x2710 ? symbol_put_addr+0x30/0x30 SyS_finit_module+0x96/0xd0 do_syscall_64+0x4e/0xb0 entry_SYSCALL64_slow_path+0x25/0x25

The only obvious issue with the original patch "ASoC: rt5677: Add ACPI support" is that it adds an I2C ID instead of an ACPI ID. I don't have 36afb0ab648 so I've no idea what it is and 55e59aa0525a is "ASoC: rt5677: Move platform code to board file" which is a code motion patch and looks more like stylistic faff around the shambles that is ACPI than anything else.

Sorry, let me re-phrase. The commit: commit 89128534f925711eea1653c264683b7d14a46530 Author: John Keeping <john@metanate.com> Date: Wed Aug 24 22:06:35 2016 +0100 ASoC: rt5677: Add ACPI support The Chromebook Pixel 2015 uses this codec with the ACPI ID RT5677CE, but does not use the standard DT property names so add a new function to parse the codec properties from these ACPI properties. Also, the GPIOs are only available by index, so we need to register a mapping to allow machine drivers to access the GPIOs by name. Adds all of the code which "ASoC: rt5677: Move platform code to board file" and "ASoC: rt5677: Introduce proper table for ACPI enumeration" move around and re-work. > > support for the Chromebook), I think that 36afb0ab648 and 55e59aa0525a > > are wrong and should be reverted.

Ugh, typo on my part proving your point :) I meant _a_36afb... which is "ASoC: rt5677: Introduce proper table for ACPI enumeration". My gut feeling (and I'd be happy to be told how to poke ACPI to confirm this..) is that the ACPI table is in fact not including some information that the code expects and that's why the original patch added an I2C ID not an ACPI ID.

My best guess if you're using mainline is that this is triggered by a36afb0ab6488ea (ASoC: rt5677: Introduce proper table for ACPI enumeration) causing the ACPI core code to run and explode on whatever you've got in the tables on that system. Someone who knows what ACPI is up to should probably dig into what's going on, even if reverting fixes it that looks worryingly like we might explode on other devices.

My gut The code that's causing issues looks like it's generic ACPI code which is worrying me, it looks like it's dying setting up the PM. It could be that the trace is a bit misleading or that it's the result of earlier damage though. > feeling (and I'd be happy to be told how to poke ACPI to confirm this..) > is that the ACPI table is in fact not including some information that > the code expects and that's why the original patch added an I2C ID not > an ACPI ID. I'm pretty sure it's just that the people writing the code didn't really know how ACPI is supposed to work in Linux so used the fallback path which appears to have been copied from OF for some reason. It makes sense with OF because the IDs OF uses include the name of the part like the Linux internal IDs rather than just some random line noise like is apparently idiomatic for ACPI (this one is one of the better ones!) so there's a decent chance that a driver that gets found might do something sensible.

The only bug so far I saw is the following one https://bugzilla.kernel.org/show_bug.cgi?id=196397 ...and above commit fixes it. Can you place somewhere the bundle of the following: 1. Output file (tables.dat) of % acpidump -o tables.dat 2. Output of % cat /proc/interrupts 3. Output of % lspci -vv -xx 4. Output of % grep -H 15 /sys/bus/acpi/devices/*/status ?

I have checked those files and found that device is in the table and pretty much properly defined ACPI I2C slave. The change in the driver you referred to makes the change to modalias. Thus, I'm suspecting that your user space helper either has some hard coded values for previous case, or just broken. Can you also check is the codec module loaded (lsmod) and, if it's not, load it manually and check if sound works again. P.S. In any case you need the patch mentioned in bug #196397

Not sure what userspace helper you mean here? The kernel is oopsing, userspace shouldn't be able to do that. > P.S. In any case you need the patch mentioned in bug #196397 What is that?

In any case you need the patch mentioned in bug #196397 I've applied "ASoC: rt5677: Hide platform data in the module sources" manually to Linus' tree and still see the same problem. Perhaps there's now some missing alias information that really needs to still be provided? snd-soc-sst-bdw-rt5677-mach is not loaded and I can't manually load it later on. What user space helper configuration am I supposed to need to have now, for this to work? Thanks!

Could you double-check? Your Oops likely comes from the NULL id->driver_type reference that is removed by the commit ddc9e69b9dc2. If you still get an Oops, we need to decode it properly now to understand what's going on. thanks, Takashi

You might have cherry-picked a wrong one, I suppose? Alright, I read-things to quickly, and to be clear: (a) "ASoC: rt5677: Hide platform data in the module sources" is _not_ in Linus' tree (I confused this with a different commit) and _is_ in Mark's ASoC for-next branch currently. (b) Applying just that patch on top of Linus' tree _does_ fix my regression (an Oops and non-functional audio) with audio and now sound works well, as expected. Can we please get that as a fix for this release? Thanks!

Thanks! OK, so the fix for 4.13 would be either to cherry-pick this commit, or just to re-add "RT5677CE:00" to i2c_id temporarily as a quick band-aid fix (and remove again in 4.14). The former is cleaner, but it's bigger, while the latter is a safer oneliner at the late RC stage. I leave the decision to Mark. Takashi

I'm happier with the oneline change TBH, like you say it's pretty late in the release cycle. Can you just apply the patch directly and send it to Linus with my ack or should I put together a pull request?

Apparently you are the one who tested the commit 89128534f925 ("ASoC: rt5677: Add ACPI support") year ago. The commit states that ACPI properties that are used in Chromebook Pixel 2015 is non-standard (not the same as for DT). However, DSDT shows the opposite! I would like to ask yuo and John what is the status of that currently? Do we have any publicly available laptop with non-standard properties?

Is there any sort of "build date" or similar in the dump I provided yesterday? Every once in a while my laptop accidentally books into ChromeOS and then it might grab and apply some updates and it's not impossible that Google updated things in the interim. I'm quite happy to test patches or provide further dumps / etc from my system. You might want to start by talking with the person behind https://github.com/raphael/linux-samus to see if they know more about different versions of the hardware or at least point you towards more testers. Thanks!

Thanks! It's just a heads up to point to a potential problem with this board. I suspect Google would take care of this.

And the patch adding this was the first (and still only) time I've really looked at ACPI, so it's quite possible that I misunderstood something at the time. From memory, I think the particular problem I was referring to in the commit message was that certain GPIOs were only defined by index and not by property name (specifically "plug-det-gpios", "mic-present-gpios" and "headphone-enable-gpios"), and having dumped DSDT just now I do not see those strings appearing anywhere.
