Linux kernel source tree
855ad0f7a1
Nam Cao <namcao@linutronix.de> says: The debug_pagealloc feature is not functional on RISCV. With this feature enabled (CONFIG_DEBUG_PAGEALLOC=y and debug_pagealloc=on), kernel crashes early during boot. QEMU command that can reproduce this problem: qemu-system-riscv64 -machine virt \ -kernel Image \ -append "console=ttyS0 root=/dev/vda debug_pagealloc=on" \ -nographic \ -drive "file=root.img,format=raw,id=hd0" \ -device virtio-blk-device,drive=hd0 \ -m 4G \ This series makes debug_pagealloc functional. * b4-shazam-merge: riscv: rewrite __kernel_map_pages() to fix sleeping in invalid context riscv: force PAGE_SIZE linear mapping if debug_pagealloc is enabled Link: https://lore.kernel.org/r/cover.1715750938.git.namcao@linutronix.de Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> |

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.
