Vmalloc.h implicit functions

Vmalloc.h implicit functions

[Omar Mustafa]

Hi all,

I’m trying to install some modules but yet I fail with those errors:

error: too many arguments to function ‘__vmalloc’   157 |   
    __vmalloc(load_driver->sys_files[i].size,

./include/linux/vmalloc.h:132:14: note: declared here
      132 | extern void *__vmalloc(unsigned long size, gfp_t gfp_mask);

Hence, make fails every time.

I was hoping whether there is any solution to this problems since Bluetooth driver build for example fails and I need it working for some IoT projects I am currently working on.

And if someone could mention Linus Torvalds I’d very much appreciate it.

What out-of-tree drivers are you trying to build?  Please fix them up to
handle the new api changes.

Then fix the drivers, they are under your control :)

What exact driver is failing?

thanks,

It’s the RTL8822BE Bluetooth which I have tried each and every solution online ever existed and failed

What specific solutions did you try that failed?

And where is the code you are trying to build?  Why are you relying on
an out-of-tree driver?

thanks,

Looks like the PCI card variant has been supported for a while:

https://linux-hardware.org/index.php?id=usb:0bda-b023  says
the USB flavor is supported by drivers/bluetooth/btusb.c
with config symbols CONFIG_BT CONFIG_BT_HCIBTUSB/

There's an apparently abandoned github driver: https://github.com/lwfinger/rtl8723au_bt
that hasn't been touched in 7 years, and has a Readme that says:

> In this document, we introduce how to support rtk 8723AE/AU BT driver in Linux system.
> Support kernel version 2.6.32~3.13.0

So for us to help you, you're going to have to be a *lot* more detailed about
what kernel release you're using, what the USB/PCI/whatever device you're
working with, and where you got the driver you're trying to get working.

First, Linux kernel email conventions are that you do a "reply all", so that others
can comment even if I'm busy or don't know the answer. I've re-added kernelnewbies
to the cc: list.

Second, you still haven't said what driver you were trying to fix. The rest of us
can't help with an out-of-tree driver unless we know where it's from.

Also, can you give us what lspci or lsusb says  your widget is?

That's not what I asked for. And that's not the *driver*, that's
the *device*.

For example, this laptop has an Ethernet and a wireless card:
[~] lspci -nn |grep -i net
01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL810xE PCI Express Fast Ethernet controller [10ec:8136] (rev 07)
02:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01)

and there's no RTL810xE or QCA8565 driver.  The first actually uses the r8169
driver, and the second uses the ath9k driver. Both those drivers support a
wide range of devices.  iwlwifi is another driver that supports a whole bunch
of devices.

Meanwhile, a USB trackball I use is:

[~] lsusb | grep Track
Bus 001 Device 002: ID 045e:0023 Microsoft Corp. Trackball Optical

And those [10ec:8136], [168c:0036], and [045e:0023] are actually important, as
that is what the *HARDWARE* device identifies itself as, and what the kernel
uses to identify which driver should be used to support the device.. There are
many actual instances where the hardware device has both a USB and PCI variant
- and only one or the other is actually supported by an in-tree driver.

And you still haven't told us what driver source you're trying to compile, or
where it came from.

That is some sort of id.

We need a link to the exact source code that you are trying to build
and having problems with, in order to determine how to help you.

But step back, why are you trying to build a driver out of the kernel
tree?  Why does the latest kernel release not support your device
already?
