AArch64: Use ARM64 machines for LUV project compilation
by Naresh Bhat
Hi,
The LUV project is successfully compiled on ThunderX Workstation
natively. The native compilation issue is fixed long time ago and I
am really quite surprised to see nothing has been broken for both LIVE
and NETBOOT/PXE images.
Logs of LIVE/NETBOOT compilation on ThunderX2 workstation :

[PATCH] meta-luv/utils: Introduce a script that creates bootable USB stick with LUV
by Sai Praneeth Prakhya
Commit 34d5d0cbce11 ("luv-live-image: Support both MBR and GPT type live
images") introduced luv-live-image-gpt.img. When a bootable USB stick is
created by dd'ing luv-live-image-gpt.img the following warning messages are
seen in dmesg
GPT:Primary header thinks Alt. header is not at the end of the disk
GPT:Alternate GPT header not at the end of the disk
Kernel spits these warning messages because luv-live-image recipe creates
GPT headers (Primary and Alternate) on luv-live-image-gpt.img file and not
on the real disk that was flashed with luv-live-image-gpt.img file. To fix
these errors the GPT headers should be created at the beginning and ending
of the real disk. This issue cannot be fixed with the present setup because
prior to creating luv-live-image-gpt.img file there is no way to know the
size of block device that LUV would be flashed onto. Hence, introduce
flash_luv.sh that can be used by a user to create a bootable USB stick with
LUV after he has decided upon the block device.
Please note that only GPT image is affected with this issue and
flash_luv.sh is not needed if booting luv-live-image-mbr.img or
luv-netboot-image.

+
+X. Create bootable GPT LUV USB stick
+====================================
+
+What is flash_luv.sh?
+---------------------
+flash_luv.sh is a bash script that creates a bootable block device (Eg: USB
+stick) with LUV. It takes 3 arguments as inputs and the third argument is
+optional.
+
+Why do we need flash_luv.sh when we already have luv-live-image-gpt.img?
+------------------------------------------------------------------------
+When a bootable USB stick is created by dd'ing luv-live-image-gpt.img the
+following warning messages are seen in dmesg
+
+ GPT:Primary header thinks Alt. header is not at the end of the disk.
+ GPT:Alternate GPT header not at the end of the disk
+
+These errors happen because luv-live-image recipe creates GPT headers (Primary
+and Alternate) on luv-live-image-gpt.img file and not on the real disk that was
+flashed with luv-live-image-gpt.img file. To fix these errors the GPT headers
+should be created at the beginning and ending of the real disk. This issue
+cannot be fixed with the present setup because prior to creating
+luv-live-image-gpt.img file there is no way to know the size of block device
+that LUV would be flashed into. Hence, have a script do that when the user has
+decided upon the block device.
+
+How to run?
+-----------
+sudo ./flash_luv.sh sdX relative-path-to-luv-boot-image [LUV_results_size]
+
+Please note that only a sudoer could run this script because it flashes LUV onto
+a block device.
+
+Detailed explanation about arguments:
+-------------------------------------
+The first argument is a block device. Typically it's denoted as sdX. "lsblk" can
+be used to find out the name of block device. Please note that it's user's
+responsibility to give the right block device. Giving a wrong block device (eg:
+HDD/SSD that has OS) would overwrite that device with LUV.
+
+The second argument is relative path to *LUV boot image* and not luv-live-image.
+The latter has both boot and results partition packed into a single .img file
+while the former has only boot partition. Typically, after building LUV, the
+boot image can be found at
+build/tmp/deploy/images/qemux86-64/luv-live-image-qemux86-64.hddimg.
+
+The third argument is the size of LUV results partition in MiB. If the requested
+size is invalid (Eg: greater than block device size) or if the argument is not
+given then all the available space i.e. the space left after boot partition is
+allocated to LUV results partition. A valid LUV results partition size is
+between 1MiB and space left after boot partition is allocated.

[PATCH] meta-luv/utils/: Update script to modify LUV parameters
by Megha Dey
The existing modify_luv_netboot_efi.py script only helps the user modify
the netconsole parameters in the luv netboot image. This patch updates
the script to help users modify the other LUV parameters.

[PATCH] luv-test: Do not use tty as standard output for x86
by Megha Dey
Commit b12bf16 "luv-test: update standard output for luv" updated
the default standard output of LUV to ttyS0 for x86 and ttyAMA0
for ARM architectures. However, after this change it was observed that
on some x86 systems, systemd fails to use ttyS0 as Standard Output and
the system appears to hang.
By reverting the above commit, we no longer see this issue, but we do
not see test-suite logs for ARM architecture on the serial console.
Hence, selectively revert the above patch for x86 architecture.
This patch resolves the issue:
