[PATCH] recipe-core/images: Disable LUV_NETCONSOLE parameter by default in luv.cfg
by Gayatri Kammela
LUV_NETCONSOLE in luv.cfg has a default value which meant to
indicate the format of this parameter to be given by user. However, when
this feature is not in use, it complains about netconsole not being
configured and it kind of misleading that luv_netconsole feature is
absolute necessary.
Thus, it makes sense to disable this parameter by default value "none",
leaving the script run only if user provides the netconsole parameters.
luv_netconsole feature can be configured by simply changing the none
to <ipaddress, port> format when the user wishes to use this feature.

[RESULTS] [2.1-rc1] Dell Inspiron 14R 5420, A19
by Mateus Rodrigues Costa
So, I discovered about this project in 2014 and sent some results of it for
my laptop at that time.
Today, I remembered about it and decided to test luv again and send the new
results.
The results are from a Dell Inspiron 14R 5420, BIOS version is A19 (same
laptop as before).
luv version is 2.1-rc1.
The Legacy Boot Option to load from the USB device didn't work this time
too (got a Operating System Not Found message), Matt Fleming did send me a
fix for that when I reported this a long time ago, which I'm not sure if I
tested. So, I had to manually add a UEFI boot option again.
Thanks,

[v1 PATCH 0/3] Automate retrieval of Linux defconfig
by Naresh Bhat
The set of patches fix the issue github.com/01org/luv-yocto/issues/116
The first patch use KBUILD_DEFCONFIG variable to set default kernel
defconfig from kernel source path arch/TARGET_ARCH/config
Other 2 patches remove the x86, arm64 defconfig which were created/copied
manually under file/arch directory.
I did a build for x86/x86-64 and ARM64 architectures and tested for ARM64.
You can clone and extract the patches from below git repository link
https://git.linaro.org/people/naresh.bhat/luvOS/luv-yocto.git/log/?h=issu...
Changes v0->v1
* Set KBUILD_DEFCONFIG variable for x86/x86-64 and remove defconfig.
* Remove kernel-yocto.bbclass changes.
* Add do_kernel_configme_append() function in yocto linux kernel recipe
to merge kernel fragments.

+Usage in Bits
+------------
+Implementation of luv_netconsole in BITS helps us capture the BITS log, thus
+achieving fully automated network debugging support in LUV. However, the usage
+of netconsole in BITS varies slightly as luv-netconsole in LUV provides the
+support by sending the messages via UDP, whereas BITS only
+supports sending the debug info via TCP socket.
+
+on the remote machine, use netcat as usual and since UDP is not supported, get

[PATCH v4 1/2] bits_git.bb: Add patch that enables network debug in BITS
by Gayatri Kammela
Include a patch that enables the debugging via network feature using
TCP/IP protocol in the bits recipe.
The luv_netconsole feature is utilized only to get kernel logs leaving
BITS alone. With this patch, it is possible to collect BITS logs as
well, thus LUV will have fully functional network debugging feature.
The usage of netconsole in BITS is similar to netconsole in luv except,
that BITS does not have UDP support yet.
example(on the remote side): $ netcat -l <port number>

Changes since v3:
1)Initilaized/imported netconsole module before importing luv so as to capture
every time stamp on the remote side.
2) Updated the README according to the comments
Changes since v2:
1)Renamed and modified luv_netconsole_log.py to be more readable
Changes since v1:
1) Included the patch that actually enables the netconsole in bits in one single patch.
2) Updated the README to include the steps to use netconsole in bits.

[PATCH] pmtools: Add recipe for pmtools, so that we get acpidump working
by Sai Praneeth Prakhya
From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com>
LUV runs FWTS and usually FWTS reports numerous failures related to
ACPI. To debug these failures, a BIOS engineer will most probably want
to look at contents in the ACPI tables and hence we should support
acpidump tool. "acpidump", dumps a system's ACPI tables to an ASCII file
and typically this ASCII acpidump output is converted to raw binary
tables using "acpixtract". Both these tools are part of pmtools, so
let's include pmtools in LUV.

[PATCH v3 1/2] bits_git.bb: Add patch that enables network debug in BITS
by Gayatri Kammela
Include a patch that enables the debugging via network feature using
TCP/IP protocol in the bits recipe.
The testsuites that run after the kernel boots have debug via network
feature(also known as netconsole)already, leaving BITS alone. With this
patch LUV will have fully functional network debugging feature.
The usage of netconsole in BITS is similar to netconsole in luv except,
that BITS does not have UDP support yet.
example(on the remote side): $ netcat -l <port number>

Changes since v2:
1)Renamed and modified luv_netconsole_log.py to be more readable
Changes since v1:
1) Included the patch that actually enables the netconsole in bits in one single patch.
2) Updated the README to include the steps to use netconsole in bits.

+Subject: [PATCH] Bits-init.py: Enable logging/debugging in bits via network
+
+BITS has socket module implemented, with which the host machine(where
+the BITS testsuite is running) can now, able to communicate with the
+remote machine via TCP/IP protocol.
+
+Leveraging the feature of communication with the remote machine for our
+debugging purposes can be useful especially, when there is no serial
+cable available.
