====================
Local vmtest enhancement and RV64 enabled
Patch 1-3 fix some problem about bpf selftests. Patch 4 add local rootfs
image support for vmtest. Patch 5 enable cross-platform testing for
vmtest. Patch 6-10 enable vmtest on RV64.
We can now perform cross platform testing for riscv64 bpf using the
following command:
PLATFORM=riscv64 CROSS_COMPILE=riscv64-linux-gnu- \
tools/testing/selftests/bpf/vmtest.sh \
-l <path of local rootfs image> -- \
./test_progs -d \
\"$(cat tools/testing/selftests/bpf/DENYLIST.riscv64 \
| cut -d'#' -f1 \
| sed -e 's/^[[:space:]]*//' \
-e 's/[[:space:]]*$//' \
| tr -s '\n' ',' \
)\"
For better regression, we rely on commit [0]. And since the work of riscv
ftrace to remove stop_machine atomic replacement is in progress, we also
need to revert commit [1] [2].
The test platform is x86_64 architecture, and the versions of relevant
components are as follows:
QEMU: 8.2.0
CLANG: 17.0.6 (align to BPF CI)
ROOTFS: ubuntu noble (generated by [3])

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
