We are working on imx8qm-mek platform running on Android 9 automotive. I was going through menuconfig and i found that none of the compression methods are enabled :
HAVE_KERNEL_GZIP || HAVE_KERNEL_BZIP2 || HAVE_KERNEL_LZMA || HAVE_KERNEL_XZ || HAVE_KERNEL_LZO || HAVE_KERNEL_LZ4
I checked these configs and i found (n) to each of them.
What does this mean ?
How can change compression method ?
How can i use decompressed kernel instead of compressed one ?
Is it good idea to use decompressed kernel for boot time optimization ?
Request you to provide some light here.
