Reserve a 2 MiB memory region to record kmsg dumps, console, ftrace and userspace messages. The implemented memory split allows capturing and reading corresponding ring buffers: * dmesg: 6 dumps, 128 KiB each * console: 128 KiB * ftrace: 128 KiB for each of 8 CPUs (1 MiB total) * userspace messages: 128 KiB Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org> --- arch/arm64/boot/dts/exynos/exynos850-e850-96.dts | 15 +++++++++++++++ 1 file changed, 15 insertions(+)
