Additionally, it doesn't always happen. It seems to happen on the first load of the module, however, running modprobe -r && modprobe in a loop (with the powerdown properly modified so the log isn't full of splats), it doesn't seem to occur every time.

But as I mentioned above, this also looks broken as qcadev->init_speed is never set anywhere. You could investigate and clean up this code before or after adding support for wcn6855, but the above really doesn't look right and would at least need to go in a separate patch with a proper explanation. > > > > > > if (qcadev->oper_speed) > > > @@ -1723,7 +1725,8 @@ static int qca_setup(struct hci_uart *hu) > > > > > > bt_dev_info(hdev, "setting up %s", > > > qca_is_wcn399x(soc_type) ?

This is driver is already spamming the logs, while generally we should only be logging when things go wrong. Those info messages can probably be changed to dev_dbg(), but that's a separate issue and not something that's needed to add support for wcn6855. And same here, you can keep the above as is, but it seems like someone will soon need to clean up the type handling as all these conditionals are getting a bit unwieldy. > > > @@ -1883,6 +1888,20 @@ static const struct qca_device_data qca_soc_data_wcn6750 = { > > > .capabilities = QCA_CAP_WIDEBAND_SPEECH | QCA_CAP_VALID_LE_STATES, > > > }; > > > > > > +static const struct qca_device_data qca_soc_data_wcn6855 = { > > > + .soc_type = QCA_WCN6855, > > > + .vregs = (struct qca_vreg []) { > > > + { "vddio", 5000 }, > > > + { "vddbtcxmx", 126000 }, > > > + { "vddrfacmn", 12500 }, > > > + { "vddrfa0p8", 102000 }, > > > + { "vddrfa1p7", 302000 }, > > > + { "vddrfa1p2", 257000 }, > > > > Hmm.

With what we currently have, we end up loading hpnv21.bin for our nvm patch file, however, we actually want (at least on my Thinkpad X13s) the .b8c file from the Windows partition for our nvm patch; With the b8c file symlinked to .bin with just my patch set, I am able to connect a pair of Air Pods Gen1 to the ThinkPad and play back audio, as well as use them for input. With the .bin file that comes from linux-firmware, they will still connect, however, they will randomly disconnect, as well as the audio output is all garbled. I think, ideally, we get v6+ in, and then we can figure out what to do about the bits that Tim's patch adds. I've tried them locally, but I'm not confident enough in my knowledge to address the issues that are brought up in the code review there. > > > With power-off handling fixed, this seems to work as quite well on my > > > X13s with 6.3-rc1.

Ok, but then we need to ask Lenovo and Qualcomm to release the firmware files we need for the X13s. Until then using your patch and "hpnv21.bin" at least works to some extent. I could connect to one bluetooth speaker without noticing any problems, but I did indeed get some garbled output when connecting to another. I have not tried the .b8c file yet though, so this could possibly be some other incompatibility issue. > I think, > ideally, we get v6+ in, and then we can figure out what to do about > the bits that Tim's patch adds.

Your patch is more complete in that it adds supports for managing power. Adding support for more fine grained loading of "NVM configuration" files could be done on top. > > > > With power-off handling fixed, this seems to work as quite well on my > > > > X13s with 6.3-rc1.

Yeah, I don't think that message during probe should be a show stopper here. Johan

I just tried with the hpnv21.b8c from the (somewhat old) windows installation on my x13s, but the bluetooth speaker that produced garbled output with the firmware from linux-firmware still does so with the windows file.
