[PATCH V0] linux-yocto-efi-test: Use custom LINUX_VERSION_EXTENSION
by Megha Dey
Poky has recently made the LINUX_VERSION_EXTENSION weaker in commit
9cc5cf0a64d("linux-yocto: Make LINUX_VERSION_EXTENSION weaker").
Use the custom LUV kernel extension in the LUV kernel recipe to remove
the actual nvdimm drivers and keep only the testing drivers.

[PATCH 2/3] AArch64: Build grub-efi v2.02 for AArch64
by Naresh Bhat
We are trying to build and use grub across x86/ARM64 architecture.
Earlier there was no support of AArch64 in grub-efi, Hence AArch64
was dependent on upstream grub git repository. The LUV project use
to pull and build grub git repository whenever we build the project
for AArch64. But recently poky updated meta layer with grub v2.02
and LUV is rebased on top of poky. Hence we can use a common grub
across all the architecture. The luv-netboot-image also depends on
the _RDEPENDS variable.

[PATCH] linux-yocto-efi-test: Increase number of CPUS
by Naresh Bhat
Increase number of CPUs in linux yocto efi test kernel. The
Dual socket server machines will be having more number of CPUs
i.e for example 296, 224..etc. Hence increase the number of CPUs to
512. Without this patch all CPUs can't bought up while booting the
machine. Testing the LUV on those machines will be a weired behaviour
i.e. you can also possibly observe some crash, repeated messages
printing on console..etc.

[PATCH v2] bits_git.bb: Add a new file that includes the new unittest in BITS
by Gayatri Kammela
Machine Check Errors (MCE) test is added to BITS to find any errors
generated by the hardware or any specific subsystem(s). These errors
are often referred as a bank and number of banks is CPU dependent.
Each bank consists of a group of four MSRs(that we are interested
in)such as CTRL, STATUS, ADDR, MISC registers. CTRL MSR allows to
enable/disable the reporting of certain errors. STATUS MSR contains the
bits such as VAL(63)if set to 1 i.e., error occurred in this group and
if the third or fourth MSRs contain valid values.
The ADDR MSR contains the address of the failure. The value read out of
the MSR is only valid if only the status MSR reports valid. The
fourth(MISC) MSR contains misc information. It contains model specific
error codes which may vary even between the CPU models.
The tests focus on verifying if these bits in STATUS MSR are valid:
Bit 63 VAL — MCi_STATUS register valid
Bit 59 MISCV — MCi_MISC register valid
Bit 58 ADDRV — MCi_ADDR register valid (i is cpu dependent)
whereas the test results will log these details:
Physical CPU number
Global status register(also known as capability register)
Bank number(i)
Bank status register
Bank address register
Bank miscellaneous register
The Bank address register and bank miscellaneous register will be logged
only in case of occurrence of errors(mce).
The unittest reports "passed" always and reports "failure" in case of
occurrence of errors. This unittest is very unlikely to "skip" unless
the architecture does not support it.

[PATCH v6 0/3] Configure LUV to enable/disable testsuites independently
by Gayatri Kammela
Hi,
This patch series will configure all the testsuites which will leave the user
a choice of running only specific testsuite(s) if needed. Since all the
testsuites are enabled by default, user needs to explicitly remove the
keyword(s) in luv.cfg file representing the target testsuite(s) to disable.
Changes since v1:
1)Added patch that configure the bits testsuite
Changes since v2:
1)Added support for ARM architecture as well.
Changes since v3:
1)Rebased against luv-2.2-rc2
Changes since v4:
1)Fixed bug in bits patch
Changes since v5:
1)Fixed the issue of missing 'pstore-tests' in append_aarch64 line
2)Updated README file
Gayatri Kammela (3):
luv-tests: Design/build LUV such that each testsuite is enabled or
disabled independently.
Bits: Skip the BITS testsuite if and when needed
Meta-luv/README: Update the README file on the new parameter
"LUV_TESTS"

[PATCH] linux-yocto-efi-test: Add Cavium Saber config
by Naresh Bhat
The linux-yocto-efi-test kernel by default config CONFIG_NR_CPUS=64
Because of this kernel is bringings up only 64 CPUs. But the Cavium's
Saber machine has 28 physical cores on each node with 4 hyperthreads
to each physical core. So, basically kernel should bring up 224 CPUs.

[PATCH] grub: Change default tsc calibration method to pmtimer on EFI systems
by Sai Praneeth Prakhya
From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com>
The following grub patch is needed because presently grub hangs on Intel
Soc systems which use 8254 timer to calibrate TSC. This patch makes
pmtimer default instead of 8254 timer. This patch has already been
upstreamed to grub but is not a part of grub 2.02 (present version of
grub used by LUV). So, let's carry this patch in LUV until it's
released in some newer grub version.

+Subject: [PATCH] tsc: Change default tsc calibration method to pmtimer on EFI
+ systems
+
+On efi systems, make pmtimer based tsc calibration the default over the
+pit. This prevents Grub from hanging on Intel SoC systems that power gate
+the pit.

[PATCH] fwts: Fix build warning installed-vs-shipped files
by Sai Praneeth Prakhya
From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com>
FWTS-V17.11.00 adds "bash-completion" support. As a result a new
directory structure (usr/share/bash-completion) is created under FWTS
build directory after building FWTS and thus bitbake warns (as shown
below) that these files are installed and are not being shipped. There
are 3 possible solutions to fix this issue:
1. Build FWTS _without_ bash-completion feature
2. Ship this feature as a part of LUV
3. Remove this directory structure after FWTS is built
FWTS does not support disabling this feature and hence we are left with
option 2 or 3. Shipping this feature might make sense hoping that some
developer (disables splash screen) and might use this feature to debug
ACPI issues with FWTS.
WARNING: fwts-V17.11.00+gitAUTOINC+0ec5075e19-r0 do_package: QA Issue:
fwts: Files/directories were installed but not shipped in any package:
/usr/share/bash-completion
/usr/share/bash-completion/completions
/usr/share/bash-completion/completions/fwts
Please set FILES such that these items are packaged. Alternatively if
they are unneeded, avoid installing them or delete them within
do_install.
fwts: 3 installed and not shipped files. [installed-vs-shipped]
