Re: Using Virtio-gpio in guest VM
shibi590268@...
Hi Geoffroy,
I checked in the latest version of kernels(i.e., 5.18) which included the driver in question. I compiled the kernel with CONFIG_GPIO_VIRTIO=y. I see the same behavior as before. The virtio-gpio gets emulated as a PCI device. Should there be some examples or some references that was used while evaluating the virtio gpio, please share that. Thanks in Advance

Re: Using Virtio-gpio in guest VM
Yes, that’s the driver in question. I do not know if we have a version of it for the latest kernel, let’s see what the kernel team has to say about it.

Re: Using Virtio-gpio in guest VM
I don’t see this anywhere in the 5.10 version, while it was there in the 4.19/preempt-rt. I suspect that means it’s a driver that was never upstreamed (or is still in the process of being upstreamed).
Is using the 4.19 kernel an option for you?
Does anyone from the kernel team know if there is a version of that driver for the 5.10 preempt-rt kernel?
Thanks, Geoffroy

Hi
I am using the ACRN patched rt kernel from https://github.com/projectacrn/acrn-kernel.git with 5.10/prempt-rt branch to use it in RTVM. I am unable to locate CONFIG_VIRTIO_GPIO=Y in the config. Is there any separate patch available for this? Attached is the .config file

Using Virtio-gpio in guest VM
shibi590268@...
Hello,
I need to use two gpio pins from a VM. I used -s 10,virtio-gpio,@gpiochip0{11=pin0:12=pin1} \ in the launch scripts. The kernel boots up successfully with a new pci device added 00:0a.0 PIC: Intel Corporation Device 8609. The device is getting listed as PIC: Intel Corporation Device 8609. is this correct? But i couldn't find the gpio device listed under /dev/ ls /dev/gpio
ls: cannot access '/dev/gpio': No such file or directory
or in /sys/class/gpio ls /sys/class/gpio/
export unexport
ls /sys/bus/gpio/devices/
ubunturt@ubunturt-Standard-PC-i440FX-PIIX-1996:~$
I couldn't find virtio-gpio module in kernel. So I used a patch from https://lkml.iu.edu/hypermail/linux/kernel/2108.1/01975.html. But still i am not successful in this. Is there anything that i am missing? Is there any patch recommendation available that could be used. User VM: ubuntu Service VM : ubuntu I am using ACRN hypervisor: v2.8
