Bootargs in RPI not working

[Sai Kiran Kumar Reddy Y]

Hi,

I have U-Boot 2022.10 version. I am trying to boot Raspberry Pi(Model 3B+)
using U-Boot. In the U-Boot terminal when I set kernel command-line
arguments, using "setenv bootargs root=/dev/mmblk0p3 ro rootwait
console=serial0,115200 console=tty1", the Kernel is not loaded. Following
are the messages I get on the U-boot terminal

" EFI stub: Booting Linux Kernel...
EFI stub: EFI_RING_PROTOCOL unavailable
EFI stub: Using DTB from configuration table
EFI stub: exiting boot services..."

When I do not add any bootargs variables to U-Boot environment, Pi boots
with Linux. Am I missing something? I am not able to figure out the reason
for this. Could you help me with this?

Create a Virtual NVME Disk

[Sai Kiran Kumar Reddy Y]

Hi,

I am Sai Kiran. I have built qemu from source on a Linux based machine. I
want to create a virtual NVME disk on my system, using QEMU. The
documentation I have seen in QEMU so far discusses providing a virtual nvme
disk to a VM. I do not want to give the virtual nvme to a VM. I want it on
my host. In other words, I want to see the virtual NVME disk under /dev
folder.

I could not create the virtual nvme disk using the qemu-img command. I have
just started working with QEMU, to create virtual disks. I am not quite
sure how to create a virtual nvme disk on the host itself, using qemu. It
would be of great help to me if someone could show me how to do this.

Thanks in advance for your help and support.

Virt-Viewer libspice-client-glib dependency

[Sai Kiran Kumar Reddy]

Hi,

I am Sai Kiran. I am trying to build virt-viewer-11.0, on my LInux From
Scratch(LFS) machine. I have installed all the dependencies of virt-viewer.
I have built the virt-viewer, with spice enabled. When I run the
virt-viewer command, I get the following error
"libspice-client-glib-2.0.so.8: cannot open shared object file: No such
file or directory. " But the shared object is present in "/usr/lib64".

I am not sure what the issue is. It would be of great help to me if someone
could help me out here.

Thanks in advance.

I have looked at all .pc files in my system. I have included the
appropriate paths in PKG_CONFIG_PATH. I am not able to find
gstreamer-app-1.0.pc in my system. Could it be some problem with my
gstreamer installation? I had resolved all the dependencies and installed
it properly, though.

Installing Gstreamer for SPICE

[Sai Kiran Kumar Reddy]

Hi,

I am Sai Kiran. I am trying to install virt-viewer on my Linux From
Scratch(LFS) machine. I see that one of the dependencies is Gstreamer. I
have built and installed Gstreamer. When I compile spice-gtk, I get the
error saying "Dependency "gstreamer-app-1.0" not found". I am not sure if
this is part of gstreamer or it is a different one. I am not able to find
the source code for gstreamer-app-1.0.

Could someone help me with this?

Thanks in advance for the help and support.

Hi Peter,

Thanks for your inputs. I have looked at all the dependencies and built
libvirt with the appropriate dependencies enabled. I am able to run
virt-manager also, without any errors. I am trying to create a VM using

Re: libvirtd daemon missing in LFS

[Sai Kiran Kumar Reddy]

Hi,

There was some issue with pkg-config-path. I have fixed it. I see that it
looks for wireshark and other dependencies. I get an error saying "remote
driver is required for libvirtd daemon". I am not sure what this error
means. Does it mean that I have to install wireshark or is it looking for
something else. Could you please help me out here.

Hi,

Thanks for your inputs. I have compiled with -Ddriver_libvirtd=enabled
option. As you have mentioned, it shows missing dependencies. Let me
install them and try to get libvirtd up and running.

Once again, thanks for your help.

libvirtd daemon missing in LFS

[Sai Kiran Kumar Reddy]

Hi,

I am Sai Kiran. I am trying to build libvirt from source on my Linux From
Scratch(LFS) system. I have successfully installed libvirt and its
dependencies. When I start virt-manager, there is a prompt in GUI saying
that "libvirtd service is not installed".  I also do not see any libvirtd
in my system. I would like to install the libvirtd service(build from
source). But I am not able to find the source code for it and also, I am
not sure about the build process for the daemon. Could you please help me
out here.

Thanks in advance for your time and support.

Xen on LFS

[Sai Kiran Kumar Reddy]

Hi,

I am Sai Kiran. I am currently working on installing xen on Linux From
Scratch(LFS) system. One of the dependencies of xen is "xorg" package. This
package is present in Beyond
 Linux From
Scratch(BLFS) 
manual. But, there are a lot of packages to be installed. I am not sure if
all these packages are required for Xen. Also, is xorg a must, to build and
install xen?

Kindly help me out here. Thanks in advance, for the support.

Sai Kiran.

Re: Xen Booting Problem on ARM Machine

[Sai Kiran Kumar Reddy Y]

Hi,

Thanks for your inputs. As you have mentioned, I tried to boot Xen directly
from EFI, thereby skipping GRUB. I made sure that kernel, xen.cfg and
ramdisk are on the first FAT partition. I still get "All 128 bootinfo
membanks exhausted error". The following link has my grub.cfg config. file
and also the snapshot of the error.

Link:
https://drive.google.com/drive/folders/1o7WT5oB7UsaZBeY5m4mWSidT5NalzvvJ?usp=sharing

I feel that even with EFI bootloader, there's some issue with bootinfo mem
banks and it maynot be a bug in GRUB. Let me know your thoughts on this.

Thanks in advance,

Regards,
Sai Kiran.

Hi

I got the code from Gitlab and installed it, enabling ACPI support in Xen.
As I reboot the system, I am able to see 2 options like before.
Option 1: Debian with latest kernel
Option 2 : Debian with Xen

I have selected Option 2. I did not see any bootinfo membanks error.
However, there is the following error in GRUB(just for a fraction of a
second).

"Using modules provided by boot loader in FDT
  Xen 4.16-unstable (c/s Wed Oct 13 13 13:28:43 2021 -0700 git:4cfab4425d)
EFI Loader
  Couldn't obtain the File System Protocol Interface: ErrCode:
0x8002"

I have enabled earlyprintk. I do not see any messages in the Serial. There
seems to be some problem with the gitlab version of Xen.

also tried to get DT info, from "/sys/firmware/devicetree/base" . But,
there's no info. under devicetree folder. I am not quite sure how to get
the DT info, if the Linux is booting from ACPI. I am attaching .dsl files,
that contain the acpi info.

[git-users] GIT Private Server on FreeBSD

[Sai Kiran Kumar Reddy Y]

Hii

I am trying to set up a private git server on FreeBSD Machine. I am trying 
to use smart-http to authenticate. I am attaching apache configuration 
file(httpd.conf) in "/usr/local/etc/apache24/". My git repos are present 
inside the folder: /home/git/repos/
test.git is a bare repository.

I have set http.receivepack to true in my repo. I am able to clone the repo 
from another host. But when I try to push the changes, I get the following 
error:

"error: Cannot access URL http://192.168.1.9:80/git/test.git/, return code 
22
fatal: git-http-push failed 
error: failed to push some refs to 'http://192.168.1.9:80/git/test.git/;

I have spent several days, editing the Apache config. settings, but with no 
use. Can someone help with this?

-Thanks
Sai Kiran.

Re: Xen Booting Problem on ARM Machine

[Sai Kiran Kumar Reddy Y]

Hi,

Sorry about the delay. We have been trying to access the serial of the
machine. Tried with couple of JTAG connectors. There's still no debug
messages on the serial. Is there any other way of figuring this out?

Sai >> Yes, I have enabled earlyprintk.
I tried changing NR_MEM_BANKS(in xen/include/asm-arm/setup.h) value to 256,
from 128. The error message is no longer seen, but the device is stuck in
the boot process.
