pci_alloc_irq_vectors fails ENOSPC for XPS 13 9310

pci_alloc_irq_vectors fails ENOSPC for XPS 13 9310

[Thomas Krause]

Hello,

some variants of Dell XPS 13 9310 model have a QCA6390 device and I was 
trying to make it work using the  ath.git master branch (tag 
ath-202010011934).

Unfortunatly, I get the following error messages when loading the module:

-28 seems to reference ENOSPC, which seems to be related to the minimum 
number of vectors not beeing available. lspci output is

It there anything in my side I can to to fix the vector allocation or is 
the XPS 13 9310 just not supported? Bluetooth works with this kernel 
version, only Wifi fails.

Best,

Do you happen to know which models exacly have it? I'm trying to find a
reasonably priced laptop with QCA6390 from Finland or EU, no luck yet.
Apparently there was a certain Dell XPS 15 9500 model but it was almost
4k EUR.

I had the same problem as well back in the days, for me enabling
CONFIG_IRQ_REMAP helped. If it helps for you also I wonder if we should
mention that in the ath11k warning above :)

Dell at least sold the XPS 13 9310 with 32 GB RAM in Germany 
(https://www.dell.com/de-de/shop/laptops/neu-xps-13/spd/xps-13-9310-laptop/cn93212) 
with the QCA6390 device. With around 2300 EUR, this offer is still 
expensive but it's less than the 4000. In the delivery notes they called 
the Wi-Fi card "Killer Wi-Fi 6 AX500-DBS (2 x 2)" (part number 555-BFPF) 
but in the current version of the linked listing this is now "Killer 
Wifi 7 AX500". I'm not sure if the "DBS" part has anything to say.

CONFIG_IRQ_REMAP did not do the trick. I noticed that the Wi-Fi card is behind a PCI bridge which is also disabled, could this be a problem?

Yeah, that's more reasonable price for a laptop. Thanks, this is very
good info. I'll try to find one from Finland.

I don't know enough about PCI to say if the bridge is a problem or not.
I'm adding linux-wireless and linux-pci in someone can help. Also Devin
seems to have a similar problem.

To summarise: Thomas is reporting[1] a problem with ath11k on QCA6390
PCI device where he is not having enough MSI vectors. ath11k needs 32
vectors but pci_alloc_irq_vectors() returns -ENOSPC. PCI support is new
for ath11k and introduced in v5.10-rc1. The irq allocation code is in
drivers/net/wireless/ath/ath11k/pci.c. [2]

Can PCI folks help, what could cause this and how to debug it further?

I would first try with a full distro kernel config, just in case there's
some another important kernel config missing.

I don't think the bridge is an issue here.  AFAICT the bridge's I/O
and prefetchable memory windows are disabled, but the non-prefetchable
window *is* enabled and contains the space consumed by the ath11k
device:

  00:1c.0 PCI bridge: Intel Corporation Device a0b8 (rev 20)
	Bus: primary=00, secondary=56, subordinate=56, sec-latency=0
	Memory behind bridge: 8c300000-8c3fffff [size=1M]
  56:00.0 Network controller: Qualcomm Device 1101 (rev 01)
     Region 0: Memory at 8c300000 (64-bit, non-prefetchable) [size=1M]

This code is needlessly complicated.  If you absolutely need
msi_config.total_vectors and can't settle for any less, you can do
this:

  num_vectors = pci_alloc_irq_vectors(ab_pci->pdev,
                                      msi_config.total_vectors,
                                      msi_config.total_vectors,
                                      PCI_IRQ_MSI);

  if (num_vectors < 0) {
    ath11k_err(ab, "failed to get %d MSI vectors (%d)\n",
               msi_config.total_vectors, num_vectors);
    return num_vectors;
  }

But it seems a little greedy if the device can't operate at all unless
it gets 32 vectors.  Are you sure that's a hard requirement?  Most
devices can work with fewer vectors, even if it reduces performance.

I don't think the bridge is an issue here.  AFAICT the bridge's I/O
and prefetchable memory windows are disabled, but the non-prefetchable
window *is* enabled and contains the space consumed by the ath11k
device:

  00:1c.0 PCI bridge: Intel Corporation Device a0b8 (rev 20)
	Bus: primary=00, secondary=56, subordinate=56, sec-latency=0
	Memory behind bridge: 8c300000-8c3fffff [size=1M]
  56:00.0 Network controller: Qualcomm Device 1101 (rev 01)
     Region 0: Memory at 8c300000 (64-bit, non-prefetchable) [size=1M]

This code is needlessly complicated.  If you absolutely need
msi_config.total_vectors and can't settle for any less, you can do
this:

  num_vectors = pci_alloc_irq_vectors(ab_pci->pdev,
                                      msi_config.total_vectors,
                                      msi_config.total_vectors,
                                      PCI_IRQ_MSI);

  if (num_vectors < 0) {
    ath11k_err(ab, "failed to get %d MSI vectors (%d)\n",
               msi_config.total_vectors, num_vectors);
    return num_vectors;
  }

But it seems a little greedy if the device can't operate at all unless
it gets 32 vectors.  Are you sure that's a hard requirement?  Most
devices can work with fewer vectors, even if it reduces performance.

Have you enabled VT-d from BIOS? This is required at least on some old 
laptops.

Good to know that the bridge shouldn't be the problem. Do you have any
ideas how to make more vectors available to ath11k, besides
CONFIG_IRQ_REMAP? Because QCA6390 works in Windows I doubt this is a
hardware problem.

True, this should be cleaned up. But of course this won't solve the
actual problem.

This was my first reaction as well when I saw the code for the first
time. And the reply I got is that the firmware needs all 32 vectors, it
won't work with less.

Good point, actually I have not. I'll add both ath10k and ath11k lists
to lore. It's even more important now that lists.infradead.org had a
hard drive crash and lost years of archives.

I do see a couple other drivers that are completely inflexible (they

Or you could just add linux-wireless, e.g.,

  L:      ath11k@lists.infradead.org
  L:      linux-wireless@vger.kernel.org

or even consider moving from ath10k and ath11k to
linux-wireless@vger.kernel.org.  I think there's some value in
consolidating low-volume lists.  It looks like ath11k had < 90

Interrupt remapping only helps when the device supports only MSI (not
MSI-X) because x86 (kernel) does not support multiple MSI interrupts
without remapping.

So if only MSI is available then you get exactly _one_ MSI vector
without remapping.

>> >> > CONFIG_IRQ_REMAP did not do the trick.

The config alone does not help. The hardware has to support it and the
BIOS has to enable it.

Check the BIOS for a switch which is named 'VT-d' or such. It might
depend on 'Intel Virtualization Technology' or such.

So I grabbed the PCI info from the link and it has:

     Capabilities: [50] MSI: Enable- Count=1/32 Maskable+ 64bit-

So no MSI-X, ergo only one MSI interrupt without remapping.

Right, even most high end network cards work with one interrupt.

Can I have a full dmesg please?

Please enable CONFIG_IRQ_REMAP and CONFIG_INTEL_IOMMU (not strictly
required, but it's a Dell BIOS after all). Also set
CONFIG_INTEL_IOMMU_DEFAULT_ON.

Or simply try a distro kernel.

Just to put more information to this:

Enforcing 32 vectors with MSI is beyond silly. Due to the limitations of
MSI all of these vectors will be affine to a single CPU unless irq
remapping is available and enabled.

So if irq remapping is not enabled, then what are the 32 vectors buying?
Exactly nothing because they just compete to be handled on the very same
CPU. If the design requires more than one vector, then this should be
done with MSI-X (which allows individual affinities and individual
masking).

That's known for 20 years and MSI-X exists for exactly that reason. But
hardware people still insist on implementing MSI (probably because it
saves 0.002$ per chip).

But there is also the firmware side. Enforcing the availability of 32
vectors on MSI is silly to begin with as explained above, but it's also
silly given the constraints of the x86 vector space. It takes just 6
devices having the same 32 vector requirement to exhaust it. Oh well...

I attached a full dmesg with the latest ath11k master and the 
configuration enabled. VT-d was enabled in BIOS. Most options have been 
already been present in the previous attempts (copied from the distro 
config) but CONFIG_INTEL_IOMMU_DEFAULT_ON needed to be set manually. I 
hope this helps, if there is more I can do to debug it on my side I'm

I attached a full dmesg with the latest ath11k master and the 
configuration enabled. VT-d was enabled in BIOS. Most options have been 
already been present in the previous attempts (copied from the distro 
config) but CONFIG_INTEL_IOMMU_DEFAULT_ON needed to be set manually. I 
hope this helps, if there is more I can do to debug it on my side I'm 
happy to do so.

which disables interrupt remapping and therefore the driver gets only
one MSI which makes it unhappy.

Not that I'm surprised, it's Dell.... Can you check whether they have a
BIOS update for that box?

I was told that on Dell XPS 15 (with a working QCA6390 setup) there's a

separate "Virtualisation" setting in BIOS. See if you have that and try
enabling it.

Thanks for the advise. I already configured the BIOS and kernel in this
way. I also update the BIOS XPS 13 9310 Bios to 1.1.1, but the 

 "DMAR: [Firmware Bug]: Your BIOS is broken; DMAR reported at address 0!"

still remains and therefor the 

 "failed to get 32 MSI vectors, only -28 available"

message.

The really bad thing is that the Killer Wi-Fi 6 AX500-DBS QCA6390 is
solder on the mainboard :-(

I was informed about another setting to test: try disabling "Enable
Secure Boot" in the BIOS. I don't know yet why it would help, but that's
what few people have recommended.

Please let me know how it goes.

I have two options under "Virtualization" in the BIOS: "Enable Intel 
Virtualization Technology (VT)" and "VT for Direct I/O". Both were 
enabled. Secure boot was also turned off. BIOS version is also at the 
most current version 1.1.1. Because of the dmesg errors Thomas Gleixner 
mentioned, I assume it would be best to contact Dell directly (even if 
I'm not sure if and how fast they will respond). If the driver would 
manage to work with only 1 vector, I assume this would also make it work 
on my configuration, even with possible performance hits.

Best,

Thomas

This is good to know, thanks for testing. Now we have explored all
possible BIOS options as I know of.

I have asked our people to report this to Dell, but no response yet.

This is the workaround we are working on at the moment. There's now a
proof of concept patch but I'm not certain if it will work. I'll post it
as soon as I can and will provide the link in this thread.

The proof of concept patch for v5.10-rc2 is here:

https://patchwork.kernel.org/project/linux-wireless/patch/1605121102-14352-1-git-send-email-kvalo@codeaurora.org/

Hopefully it makes it possible to boot the firmware now. But this is a
quick hack and most likely buggy, so keep your expectations low :)

In case there are these warnings during firmware initialisation:

ath11k_pci 0000:05:00.0: qmi failed memory request, err = -110
ath11k_pci 0000:05:00.0: qmi failed to respond fw mem req:-110

Try reverting this commit:

I also see this -22 error (see my logs in [1]), even when the firmware
reboots normally. Do you see anything after these messages?

The problem which reverting 7fef431be9c9 helps has these errors:

ath11k_pci 0000:06:00.0: qmi failed memory request, err = -110
ath11k_pci 0000:06:00.0: qmi failed to respond fw mem req:-110

Sorry for the top posting, web email has ruined my mailing list
etiquette.  It seems having the correct firmware in place has caused
some forward movement.  I now see this:

Occasionally my kernel is panic'ing at random spots (this is probably
related to the other patch I guess), but I do have a bit of an adapter
now ,ifconfig shows it.  I don't seem to be able to find any networks
with it however.

Applying the patch and revert patch 7fef431be9c9 worked on the first
glance.

After a couple of minutes the connection get broken. The kernel log
shows the following error:

ath11k_pci 0000:55:00.0: wmi command 16387 timeout
ath11k_pci 0000:55:00.0: failed to send WMI_PDEV_SET_PARAM cmd
ath11k_pc
i 0000:55:00.0: failed to enable PMF QOS: (-11

It is also not possible to unload the ath11k_pci, rmmod will hang.

Applying the patch and revert patch 7fef431be9c9 worked on the first
glance.

After a couple of minutes the connection get broken. The kernel log
shows the following error:

ath11k_pci 0000:55:00.0: wmi command 16387 timeout
ath11k_pci 0000:55:00.0: failed to send WMI_PDEV_SET_PARAM cmd
ath11k_pc
i 0000:55:00.0: failed to enable PMF QOS: (-11

It is also not possible to unload the ath11k_pci, rmmod will hang.

I can confirm the same behavior as Stefani so far.  After applying the
patch, and reverting commit 7fef431be9c9, I am able to connect to a
network.  It hasn't disconnected yet (I'm sending this email via that
connection).  I'll report what I find next.

Thanks again for the help!

Re: pci_alloc_irq_vectors fails ENOSPC for XPS 13 9310

I've yet to see any instability after 45 minutes of exercising it, I
do see a couple of messages that came out of the driver:

[    8.963389] ath11k_pci 0000:55:00.0: Unknown eventid: 0x16005
[   11.342317] ath11k_pci 0000:55:00.0: Unknown eventid: 0x1d00a

then when it associates:

[   16.718895] wlp85s0: send auth to ec:08:6b:27:01:ea (try 1/3)
[   16.722636] wlp85s0: authenticated
[   16.724150] wlp85s0: associate with ec:08:6b:27:01:ea (try 1/3)
[   16.726486] wlp85s0: RX AssocResp from ec:08:6b:27:01:ea
(capab=0x411 status=0 aid=8)
[   16.738443] wlp85s0: associated
[   16.764966] IPv6: ADDRCONF(NETDEV_CHANGE): wlp85s0: link becomes ready

The adapter is achieving around 500 mbps on my gigabit connection, my
2018 mbp sees around 650, so it's doing pretty well so far.

Stefani - when you applied the patch that Kalle shared, which branch
did you apply it to?  I applied it to ath11k-qca6390-bringup and when
I revert 7fef431be9c9 there is a small merge conflict I needed to
resolve.  I wonder if either the starting branch, or your chosen
resolution are related to the instability you see (or I'm just lucky
so far! :)).

I used the vanilla kernel tree 
https://git.kernel.org/torvalds/t/linux-5.10-rc2.tar.gz. On top of this
i applied the 

RFT-ath11k-pci-support-platforms-with-one-MSI-vector.patch

and reverted the patch 7fef431be9c9

I did also my testing on v5.10-rc2 and I recommend to use that as the
baseline when debuggin these ath11k problems. It helps to compare the
results if everyone have the same baseline.

Absolutely, I'll rebuild to 5.10 later today and apply the same series
of patches and report back.  I'll also test out the patch on both
versions from Carl to fix resuming.  It stands to reason that we may
be seeing another regression between Stefani (5.10) and myself (5.9
bringup branch) as I don't see any disconnections or instability once
the interface is online.

Absolutely, I'll rebuild to 5.10 later today and apply the same series
of patches and report back.  I'll also test out the patch on both
versions from Carl to fix resuming.  It stands to reason that we may
be seeing another regression between Stefani (5.10) and myself (5.9
bringup branch) as I don't see any disconnections or instability once
the interface is online.

Yeah, there is something strange happening between v5.9 and v5.10 we
have not yet figured out. Most likely it has something to do with memory
allocations and DMA transfers failing, but no clear understanding yet.

But to keep things simple let's only discuss the MSI problem on this
thread, and discuss the timeouts in the another thread:

http://lists.infradead.org/pipermail/ath11k/2020-November/000641.html

I'll include you and other reporters to that thread.

Ok, I've tried a clean checkout of 5.10-rc2 with the one MSI patch
applied and 7fef431be9c9 reverted.  I can't get my machine to  boot
into anything usable with that configuration.  I'm running ubuntu so
its starting right into X and sometime between showing the available
users and me clicking the icon to login the machine freezes.  I can
see in the system tray that the wifi adapter is being activated and
appears to have associated with an AP, I just can't do much beyond
that as the keyboard backlight wakes up, but the caps lock key doesn't
work.  I see similar behavior with the 5.9 configuration, but after a
reboot or two I win whatever race is occuring.  With 5.10, I tried
maybe 10-15 times with 0 success.

Kalle, what would be a useful next move for trying to hunt this?  It
seems I can't really test the single MSI patch on 5.10 since with the
patch (+ the reverted commit) the driver isn't stable enough for my
machine to stay running.  It seems your hunch is that this is related
to the issues in the other thread
(http://lists.infradead.org/pipermail/ath11k/2020-November/000550.html)?
 I see the SOTA for debugging these things would be to use the kdump
tools and let the secondary kernel dump diagnostics for me.  Would
such logs be useful for you/this?

Thanks!

I can confirm this behavior on my configuration. I managed to login once 
and select the Wifi and connect to it. It seemed curiously enough be 
stable long enough to enter the Wifi passphrase. After the connection 
was established, the system hang and on each attempt to reboot into the 
graphical system it would freeze at some point (sometimes even before 
showing the login screen).

Kernel was both based on 5.10-rc2 and 5.10-rc3 (I did see the same 
behavior) with the patch applied, 7fef431be9c9 reverted and firmware 
downloaded and copied to /lib/firmware/ath11k/QCA6390/hw2.0/.

I did a bit more digging to see if I could find any new information,
I'm not sure I did but here's what I did / found.  I spent the time to
get a kdump kernel running and enabled, I was able to SysRq-C (both
via keyboard and echo c > /proc/sysrq-trigger) and generate a crash
dump.  Actually viewing them at the moment will require reverting a
couple of patches to printk to fix the file for the crash utility
(https://github.com/crash-utility/crash/issues/67), but right now
that's not super important since the mechanism isn't being triggered.
As reported here and by Mitchell, the adapter will work occasionally,
but more often it will hang the machine (I too tried 5.10-rc3 with no
noticable differences).  Whatever is causing the system to hang isn't
triggering the kdump kernel to take over and dump the vmcore.  I've
set watchdog=1 , nmi_watchdog=1, hung_task_panic=1, softlockup_panic=1
trying to convince the kernel to dump it's state during this.  I've
not been able to make it write a crash, it just sits 'hung'.  One
interesting observation that may be related, is that if the lockup
occurs during my login, I can actually see the system grind to a halt
over the course of a number of frames (the rendering of the login
animations starts to stutter/get really slow, then after a few frames
everything is frozen).  If something were spin locking/ed, I'd expect
the soft lockup panic to find it, but I don't know these mechanisms
well.

The only consistent behavior that I managed to create is that if the
wifi adapter / machine are in a 'working' state (ie: I can browse the
internet, etc) and I issue sysrq-c to crash the kernel and then let
the crash dump write and reboot the machine, once booted the adapter
is no longer seen by the kernel, and there are zero messages in dmesg
that match "ath11k".  The driver shows up in lsmod , but it reports
zero messages and it's like the adapter is completely invisible.  A
power off and back on of the machine will re-enter it into the
freezing/wifi working lottery.

I did a bit more digging to see if I could find any new information,
I'm not sure I did but here's what I did / found.  I spent the time to
get a kdump kernel running and enabled, I was able to SysRq-C (both
via keyboard and echo c > /proc/sysrq-trigger) and generate a crash
dump.  Actually viewing them at the moment will require reverting a
couple of patches to printk to fix the file for the crash utility
(https://github.com/crash-utility/crash/issues/67), but right now
that's not super important since the mechanism isn't being triggered.
As reported here and by Mitchell, the adapter will work occasionally,
but more often it will hang the machine (I too tried 5.10-rc3 with no
noticable differences).  Whatever is causing the system to hang isn't
triggering the kdump kernel to take over and dump the vmcore.  I've
set watchdog=1 , nmi_watchdog=1, hung_task_panic=1, softlockup_panic=1
trying to convince the kernel to dump it's state during this.  I've
not been able to make it write a crash, it just sits 'hung'.  One
interesting observation that may be related, is that if the lockup
occurs during my login, I can actually see the system grind to a halt
over the course of a number of frames (the rendering of the login
animations starts to stutter/get really slow, then after a few frames
everything is frozen).  If something were spin locking/ed, I'd expect
the soft lockup panic to find it, but I don't know these mechanisms
well.

The only consistent behavior that I managed to create is that if the
wifi adapter / machine are in a 'working' state (ie: I can browse the
internet, etc) and I issue sysrq-c to crash the kernel and then let
the crash dump write and reboot the machine, once booted the adapter
is no longer seen by the kernel, and there are zero messages in dmesg
that match "ath11k".  The driver shows up in lsmod , but it reports
zero messages and it's like the adapter is completely invisible.  A
power off and back on of the machine will re-enter it into the
freezing/wifi working lottery.

Good evening all!  Just wanted to follow up as I think I've started to
uncover some of what's happening with the XPS and this driver.  So
since I can't get the kdump kernel to dump anything for me, I took a
bit more of a naive approach.  I blacklisted the modules (ath11k /
ath11k_pci) from modprobe so I could at least control when it was
loaded.  I managed to capture a series of crashes (in phone pics, but
I'll transcribe the relevant bits here) that seem to indicate some
kind of runaway / spin locked behavior.  In all but one case[*], both
the crash and the eventual working state, the driver completely
initialized successfully with messaging like this:

[   23.677675] ath11k_pci 0000:55:00.0 wlp85s0: renamed from wlan0

So up until this point, everything is working without issues.
Everything seems to spiral out of control a couple of seconds later
when my system attempts to actually bring up the adapter.  In most of
the crash states I will see this:

[   31.286725] wlp85s0: send auth to ec:08:6b:27:01:ea (try 1/3)
[   31.390187] wlp85s0: send auth to ec:08:6b:27:01:ea (try 2/3)
[   31.391928] wlp85s0: authenticated
[   31.394196] wlp85s0: associate with ec:08:6b:27:01:ea (try 1/3)

[   31.407730] wlp85s0: associated
[   31.434354] IPv6: ADDRCONF(NETDEV_CHANGE): wlp85s0: link becomes ready

And then either somewhere in that pile of messages, or a second or two
after this my machine will start to stutter as I mentioned before, and
then it either hangs, or I see this message (I'm truncating the
timestamp):

[   35.xxxx ] sched: RT throttling activated

After that moment, the machine is unresponsive.  Sorry I can't seem to
extract this data other than screenshots from my phone at the moment,
you can see the dmesg output from 6 different hangs here:
https://github.com/w1nk/ath11k-debug

* - In the case where the driver didn't fully initialize successfully
and hung; during the initialization right after the "MSI vectors: %d"
printk, I started seeing these:

[ 77.xxx ] alloc_contig_range: [88d8e0, 88d8e9) PFNs busy

Good evening all!  Just wanted to follow up as I think I've started to
uncover some of what's happening with the XPS and this driver.  So
since I can't get the kdump kernel to dump anything for me, I took a
bit more of a naive approach.  I blacklisted the modules (ath11k /
ath11k_pci) from modprobe so I could at least control when it was
loaded.  I managed to capture a series of crashes (in phone pics, but
I'll transcribe the relevant bits here) that seem to indicate some
kind of runaway / spin locked behavior.  In all but one case[*], both
the crash and the eventual working state, the driver completely
initialized successfully with messaging like this:

So up until this point, everything is working without issues.
Everything seems to spiral out of control a couple of seconds later
when my system attempts to actually bring up the adapter.  In most of
the crash states I will see this:

[   31.286725] wlp85s0: send auth to ec:08:6b:27:01:ea (try 1/3)
[   31.390187] wlp85s0: send auth to ec:08:6b:27:01:ea (try 2/3)

[   31.407730] wlp85s0: associated
[   31.434354] IPv6: ADDRCONF(NETDEV_CHANGE): wlp85s0: link becomes ready

And then either somewhere in that pile of messages, or a second or two
after this my machine will start to stutter as I mentioned before, and
then it either hangs, or I see this message (I'm truncating the
timestamp):

[   35.xxxx ] sched: RT throttling activated

After that moment, the machine is unresponsive.  Sorry I can't seem to
extract this data other than screenshots from my phone at the moment,
you can see the dmesg output from 6 different hangs here:
https://github.com/w1nk/ath11k-debug

* - In the case where the driver didn't fully initialize successfully
and hung; during the initialization right after the "MSI vectors: %d"
printk, I started seeing these:

As this driver uses threaded interrupts, this looks like an interrupt
storm and the interrupt thread consumes the CPU fully. The RT throttler
limits the RT runtime of it which allows other tasks make some
progress. That's what you observe as stutter.

You can apply the hack below so the irq thread(s) run in the SCHED_OTHER
class which prevents them from monopolizing the CPU. That might make the
problem simpler to debug.

Thanks,

I was able to apply this patch and play a little bit.  Unfortunately,
whatever is still going on is mostly the same.  It seems this patch
extends the 'stuttering' I see a little bit, but the end result is
still an unresponsive machine.  I didn't get tons of time to play yet,
so the extra time may make it possible to finally get sysrq-c issued
and get a vmcore dump.  I also tried to replicate a google android
patch I found to basically BUG() on the rt throttling activating
(https://groups.google.com/a/chromium.org/g/chromium-os-reviews/c/NDyPucYrvRY)
but that path hasn't activated for me since I booted it.  I'll
hopefully have a chance again this evening.

VT for Direct I/O enables the IOMMU and the interrupt remapping unit,
but the kernel can't use it because the ACPI tables are busted.

but the kernel can't use it because the ACPI tables are busted.

Good luck.

Thanks for this info. The platform I have, J1900, indeed does not support VT-d.

So I guess I'm not able to use this card. That's unfortunate.

It doesn't seem like the Windows driver works either. It doesn't give any errors
but it fails to find any wireless networks.

The background here is that linux-wireless is quite high volume list and
not everyone have time to follow that, so having specific ath10k and
ath11k lists make it easier for those people. So I'm hesitant to
shutdown driver lists for that reason.

Just to provide another case, I have the same issue with this driver.

CONFIG_IRQ_REMAP=y and doesn't have any effect.

I'm unsure if the issue could be my system (Atom / Intel J1900) or the
that I'm using a slightly different card. Is there anyway to tell from the
lspci output? Here is what I guess is most relevant:
